Description

Multifunctional equipment for sludge hopper of secondary sedimentation tank Technical Field The utility model relates to the technical field of sewage treatment equipment, in particular to multifunctional equipment capable of being used for a sludge hopper of a secondary sedimentation tank. Background The secondary sedimentation tank is a core structure in the sewage treatment system and is mainly used for separating sludge and water through gravity sedimentation. The sludge hopper is used as an important structure at the bottom of the secondary sedimentation tank and is responsible for collecting and temporarily storing settled sludge. However, the conventional sludge hopper has the following problems in actual operation: 1. Sludge deposition and blockage, namely, sludge is easy to harden in a bucket due to poor fluidity or accumulation of fiber impurities, so that sludge discharge is smooth and even blocked, frequent manual cleaning is needed, and the treatment efficiency is affected; 2. The maintenance is difficult, the traditional crusher is usually fixedly arranged in the sludge hopper, and the sludge is required to be emptied and enters a narrow hopper for operation during maintenance, so that potential safety hazards exist and time is consumed; 3. the structural stability is insufficient, part of equipment is installed in a suspension mode, and the equipment is easy to deviate under the condition of sludge impact or mechanical vibration, so that the crushing effect is affected, and the service life of the equipment is prolonged. In order to solve the above problems, some improvements have been made in the prior art, such as adding a stirring device in the sludge hopper or using a screw conveyor to assist in sludge discharge. However, these solutions still have the drawbacks of low functional integration, high energy consumption or inability to simultaneously solve clogging of the sludge hopper and difficult maintenance. Therefore, development of a multi-effect device integrating crushing and lifting functions and being convenient to maintain is needed to optimize the secondary sedimentation tank sludge treatment process. Disclosure of utility model Based on the problems, the utility model provides multifunctional equipment for a sludge hopper of a secondary sedimentation tank, which aims to solve the problems of sludge blockage, low treatment efficiency, difficult equipment maintenance and the like in the sludge hopper, and realizes efficient sludge treatment and convenient equipment maintenance by integrating crushing, lifting and quick positioning functions. The multifunctional equipment for the sludge hopper of the secondary sedimentation tank comprises a crusher and a hoister, wherein the hoister is arranged on the upper part of a central upright post of the secondary sedimentation tank, the sludge hopper is arranged close to the upright post, the crusher is arranged on the upper part of the sludge hopper, a lifting rod on the hoister is vertically connected with the crusher, a pair of crushing rollers are arranged in the crusher and driven by a motor, a filter screen box is arranged at the lower outlet of the crushing rollers, and the filter screen box is arranged on the lower part of the sludge hopper. Preferably, the upper portion of the sludge bucket is provided with a mounting platform, four corners of the mounting platform are respectively provided with a positioning pin, the crusher is matched with the upper portion of the sludge bucket, so that the crusher can be firmly clamped on the upper portion of the sludge bucket, and four corners of the crusher are provided with positioning holes corresponding to the positioning pins.
