Description

Liquid injection mechanism for sewage treatment device Technical Field The utility model belongs to the technical field of sewage treatment, and particularly relates to a liquid injection mechanism for a sewage treatment device. Background The water treatment may also be referred to as wastewater treatment. The latter is a broad term and may also refer to industrial waste water. For most cities, sewer systems also discharge a portion of sewage to sewage treatment plants, which have typically been pre-treated at the plant itself to reduce the pollutant load. If the sewer system is a combined sewer it will also bring urban runoff (rain water) to the sewage treatment plant. Sewage can flow to a sewage treatment plant by the assistance of pipes and gravity and pumps. The sewage treatment is carried out by a sewage treatment plant, at present, the common sewage treatment mode is a mode of combining physics and chemistry, the sewage is mostly introduced into a reaction tank, chemical reaction is carried out by adding medicament, or a series of operations such as electrolysis are carried out, and then impurities are filtered; In the existing sewage treatment process, sewage and a reaction reagent are directly added into a reaction tank through a pipeline, and the sewage and the reaction reagent are not fully mixed and cannot react fully, so that the sewage treatment effect is affected. Disclosure of utility model The utility model aims to provide a liquid injection mechanism for a sewage treatment device, which aims to solve the problems in the background technology. The technical scheme adopted by the utility model is as follows: The utility model provides a sewage treatment plant is with annotating liquid mechanism, includes the liquid mixing jar, liquid mixing jar bottom exit intercommunication has the transfer line, both ends distribution is equipped with liquid filling opening and charge mouth about liquid mixing jar top, be equipped with in the liquid mixing jar and mix the liquid board, it locates liquid filling opening and charge mouth below to mix the liquid board, it is equipped with the buffer board to mix liquid board below center department. Preferably, the liquid mixing plate adopts a circular ring-shaped structure, an annular baffle is arranged at the center of the liquid mixing plate, and a plurality of liquid outlets are formed in the baffle. Preferably, the liquid mixing plate adopts a structure with gradually reduced height from the upper position to the lower position. Preferably, the buffer plate is arranged below the central through hole of the liquid mixing plate, adopts a structure that the heights of the buffer plate from the center to the two ends gradually decrease, and is arranged above the outlet of the liquid mixing tank. Preferably, the upper end of the infusion tube is connected with the outlet of the liquid mixing tank in a sealing way, and a spiral liquid mixing channel is arranged in the infusion tube. Preferably, the top of the liquid mixing tank is also provided with an exhaust port. In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: According to the utility model, the liquid mixing plate is arranged in the liquid mixing tank, and the spiral liquid mixing channel is arranged in the liquid conveying pipe, so that the sewage and the reaction agent are fully mixed, the full reaction of impurities in the sewage is realized, and the sewage treatment effect is improved. Drawings FIG. 1 is a schematic diagram of the overall structure of the present utility model; FIG. 2 is a cross-sectional view of a liquid blend tank of the present utility model; FIG. 3 is a cross-sectional view of an infusion tube in accordance with the present utility model; FIG. 4 is a top view of the interior of the infusion tube of the present utility model; in the figure, 31 parts of liquid mixing tank, 311 parts of medicine adding port, 312 parts of liquid adding port, 313 parts of air outlet, 314 parts of liquid mixing plate, 315 parts of baffle plate, 316 parts of liquid outlet, 317 parts of buffer plate, 32 parts of liquid conveying pipe, 321 parts of spiral liquid mixing channel. Detailed Description The following detailed description of specific embodiments of the utility model.
