Description

Filter tightness detection device Technical Field The invention relates to the field of filter production, in particular to a filter tightness detection device. Background The patent application No. CN201721104397.4 discloses a filter air tightness detection device which comprises a water tank, a water level sensor, a support frame, a controller, an air cylinder, a sealing cover, a water inlet cylinder, a support plate, a fixed cylinder and a top frame, and is characterized in that the water level sensor is stuck on the inner wall of the water tank, the support frame is fixed on the upper plane of the water tank through bolts, the controller and the air cylinder are arranged on the upper plane of the support frame through bolts, the air cylinder is communicated with the sealing cover through an air pipe, the sealing cover is communicated with an oil outlet of the filter during detection, then the air cylinder is placed in the support plate, the filter is filled in water, the water level rises, and when the water level reaches the water level sensor, the air cylinder is stopped in the filter, and then workers observe whether air bubbles exist or not, but the detection device can detect whether the air cylinder has air bubbles once, so that the detection efficiency is low. The invention is researched and proposed for overcoming the defects of the prior art. Disclosure of Invention The invention aims to overcome the defects of the prior art and provides a filter tightness detection device. The invention can be realized by the following technical scheme: The invention discloses a filter tightness detection device which comprises a bottom plate, wherein a water tank is fixed on the bottom plate, a sliding plate is arranged above the bottom plate, the sliding plate is driven to move by a test motor, a plurality of test cylinders are fixed on the sliding plate, a fixing plate is arranged below the sliding plate, the tail ends of piston rods of the test cylinders are fixed with the fixing plate, fixing blocks are symmetrically fixed on the two sides below the fixing plate, rotating shafts which are rotationally connected with the fixing blocks are arranged on the fixing blocks, the rotating shafts are driven to rotate by corresponding rotating motors, a supporting plate is fixed between the two rotating shafts, supporting grooves are uniformly arranged on the supporting plate, a positioning plate is further arranged on one side of the supporting plate, positioning grooves are uniformly arranged on the positioning plate, a plurality of electromagnets are uniformly fixed on the supporting plate, metal blocks are uniformly fixed on the positioning plate, limiting plates are uniformly fixed on the positions corresponding to the electromagnets, limiting rods are uniformly fixed on the two ends of the positioning plate, the limiting plates penetrate through and are in sliding connection with the fixing plates, a plurality of connecting blocks are fixedly connected with the connecting blocks, a water tank is fixedly arranged between the limiting plates and the lifting plates, and the connecting plates are fixedly connected with the lifting plates.
