The utility model relates to the technical field of hoppers, in particular to a lateral feeding hopper of a plastic shredder, which comprises a feeding hopper, the top end of the feeding hopper is fixedly connected with a first fixing frame, a telescopic square pipe is arranged above the first fixing frame, and the upper end and the lower end of the telescopic square pipe are fixedly connected with second fixing frames which are symmetrically arranged. Through the arrangement of a telescopic square pipe, a second fixing frame, a rubber pad, a fixing plate, a pneumatic device, a connecting pipe, an air pipe and an air pump, before the device is used, the air pump is started, and the telescopic square pipe stretches out till the top end of the rubber pad is tightly attached to the bottom end of a discharging port of a discharging device; the telescopic square pipe can isolate plastic popped out of the plastic shredding machine, after the device is used, the air pump can be started to enable the connecting rod to retract so as to clean the feeding hopper and the plastic shredding machine, and due to the design, the plastic can be prevented from popping out, and cleaning of the feeding hopper and the plastic shredding machine is not affected.

The invention belongs to the technical field of sewage treatment, particularly relates to an anti-pollution graphene flat sheet membrane assembly and water treatment equipment, and aims to solve the problems that a membrane assembly is easily polluted, large-particle impurities damage a membrane and a supporting mechanism and hinder sludge cleaning in the water treatment equipment, the assembly comprises a top seat, a base, a mounting frame, the membrane and a first cleaning mechanism, the device is composed of a gas injection box, a Venturi tube and the like and generates gas-liquid mixed turbulent flow to clean a diaphragm. The second cleaning mechanism comprises a cleaning ball and is driven by turbulent flow to clean; the protective grid frame body preliminarily filters large-particle impurities, the backwashing mechanism can remove impurities on the assembly, the water treatment equipment comprises the assembly and the sewage pool, the supporting mechanism in the pool facilitates placement and taking of the membrane assembly, sludge cleaning is not affected, the assembly is resistant to pollution, the membrane is protected, and the equipment is convenient to maintain.
