Description

Technical Field

[0001] This utility model relates to the field of screw press technology, specifically to a screw press that is easy to clean. Background Technology

[0002] Screw press sludge dewatering machines are widely used in the sludge dewatering process of sewage treatment. When the screw press sludge dewatering machine is working, the sludge enters from the sludge inlet hopper. As the screw rotates inside the machine, the sludge passes through the thickening section and the dewatering section, and is squeezed out between the end of the screw and the back pressure plate, falling out of the sludge outlet.

[0003] A search revealed existing technology (application number: CN202323306969.5), which describes "an easy-to-clean screw press dewatering machine, comprising a screw press dewatering machine body with a dewatering chamber, a spray plate disposed on the right side inside the dewatering chamber, a baffle plate disposed on the left side of the spray plate and rotatably and sealingly connected to the dewatering chamber, the baffle plate being circular and having multiple water outlets on its axial side, a circular hole disposed on the left side of the spray plate corresponding to the left and right water outlets, and the circular hole not communicating with the right side of the spray plate, a nozzle being sealed and inserted into the circular hole, with the spraying end of the nozzle facing the baffle plate, a water storage chamber disposed on the spray plate and communicating with the right end of the circular hole, the water storage chamber being connected to a water supply pipe, the other end of the water supply pipe being connected to a water pump, and the other end of the water pump being connected to a water tank, the screw press machine body having an adjustment port located on the right side of the baffle plate, and the baffle plate having a lever disposed within the adjustment port; this utility model has the advantage of being easy to clean."

[0004] While existing screw press dewatering machines that are easy to clean achieve the effect of easy cleaning, they still have some shortcomings: the spraying range of the spray plate involved in the existing screw press dewatering machine is small at one time, resulting in low cleaning efficiency; secondly, the gap between the fixed ring and the moving ring of the screw press is small, and the single spraying of water results in poor cleaning effect; in addition, the intermittent spraying of water by the spray plate leads to a waste of a lot of water.

[0010] Furthermore, an inclined tube is connected to the outside of the air blowing pipe, and an intermediate tube is connected to the upper end of the inclined tube, and the intermediate tube is connected to the outer edge of the turntable.

[0011] Furthermore, the lower end of the air pump is connected to an air collection pipe, which is fixed to the lower side of the cleaning rack, and the air collection pipe is connected to the intermediate pipe through a second flexible hose.

[0016] 2. By connecting the second housing and the drain pipe included in the filter assembly, the water filtered by the screw press can be filtered again through the filter screen, polyester fiber filter cotton and ceramic filter element inside the second housing, which facilitates the recycling of water source. In addition, the spray head can also be used as a spray device when the main body of the screw press is running, achieving the dual purpose of use and cleaning. Attached Figure Description

[0024] In this embodiment, the main body 1 of the screw press also includes a water filter tank and an internal screw, with a fixed ring and a movable ring connected to the outside of the screw, and the cleaning rack 2 is placed on the upper side of the water filter tank.

[0025] Specifically, the lower end of the water collection tank 11 is connected to a base, and the water collection tank 11 is connected to the second box 61 mentioned below through a drain pipe 111. The water collection tank 11 flows downward into the second box 61 by its own weight.

[0026] like Figure 2 In the middle, the dosing assembly 13 includes a first housing 131, and a dosing tube 134 is inserted into the inside of the first housing 131. The outer wall of the dosing tube 134 has a through hole 135. The upper end of the dosing tube 134 is connected to an expansion hopper 133, and the upper end of the expansion hopper 133 is connected to a dosing tube 132. The expansion hopper 133 is located on the upper side of the first housing 131.

[0027] As a preferred implementation, by setting up the expansion hopper 133, the flocculant can be simultaneously output downward into the delivery pipe 134. Through the pipe pressure inside the dosing pipe 132, the flocculant is then uniformly delivered to the second box 61 through multiple through holes 135, thereby achieving the effect of uniform dosing.

[0028] like Figure 1 , Figure 3 and Figure 4In the cleaning assembly 3, a turntable 31 is included, and a rotating shaft 41 is inserted and fixed at the center of the turntable 31. An air blowing pipe 33 and a nozzle 34 are connected to the lower side of the turntable 31.

The cleaning rack 2 has side plates at both ends, the motor 4 is fixed to the outer wall of the side plate, and the rotating shaft 41 is rotatably connected between the side plates.

[0031] In use, wastewater is pumped into the dosing tank, and then flocculant is added through the dosing pipe. After mixing, the mixture enters the flocculation tank for stirring, and then overflows into the filter tank of the screw press. The rotation of the screw drives the rotation of the moving ring and the fixed ring to squeeze and filter the wastewater. The filtered water then enters the collection tank, while the sludge cake is discharged through the sludge discharge hopper. The filtered water is then filtered through the filter material inside the second box of the filter assembly, and then pumped into the nozzle for recycling.

[0032] During cleaning, the cleaning components, including the turntable, connecting pipe, collecting pipe, first hose, and nozzle, facilitate the output of filtered water from the second housing to the nozzle via a water pump. The turntable is driven to reciprocate by a motor and rotating shaft, thereby achieving a wide-area cleaning. Simultaneously, while the nozzle is spraying water, the air pump, air collecting pipe, and second hose are activated. This allows high-pressure air to be blown through the air blowing pipe into the gap between the fixed ring and the movable ring on the screw during the water spray intervals, thus improving the cleaning effect.

[0033] The easy-to-clean screw press of this utility model can effectively solve the problems mentioned in the background technology. It has the advantages of enhanced cleaning effect and improved cleaning efficiency on the basis of existing easy-to-clean screw press technology, and also has the effect of water recycling.
