Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a sand-water separation device used in a sewage pump station. Background Art

[0002] The sand-water filter is an integrated device for separating and lifting organic sand in sewage. It can separate particles with a particle size of ≥0.2mm and has a high separation efficiency. The equipment usually uses a shaftless spiral. The spiral sand-water separator consists of a shaftless spiral, lining strips, U-shaped troughs, water tanks, guide plates, outlet weirs and drive devices. The working process is generally as follows: the sand-water mixture is input into the water tank from the top of one end of the separator. The heavier particles in the mixed liquid, such as sand particles, will be deposited at the bottom of the trough. Driven by the spiral, the sand particles are lifted along the inclined bottom of the trough, and continue to move a distance after leaving the liquid surface. After the sand particles are fully dehydrated, they are unloaded into the sand bucket through the sand discharge port, and the water separated from the sand and water is discharged from the overflow port and sent to the water inlet pool in the factory.

[0003] A current sewage pump station sand-water separation device, as described in the patent with publication number CN219722204U, comprises: an outer barrel and an inner barrel; the inner barrel is fixedly connected to the inner center of the outer barrel; a plurality of filter holes are provided on the side wall of the inner barrel; the center of the inner barrel is rotatably connected to a shaft; a stirring blade is fixedly connected to the bottom of the shaft; a transmission assembly is fixedly connected to the upper part of the shaft, and the transmission assembly is used for rotating and stirring the shaft; a connected drain pipe is fixedly connected to the bottom of the side wall of the outer barrel; a filter cloth is arranged at a position corresponding to the drain pipe inside the outer barrel; a filter layer is arranged between the filter cloth and the inner barrel; a cone bottom is fixedly connected to the bottom of the outer barrel, and the bottom of the inner barrel is fixedly connected to the cone bottom.

[0004] With respect to the above-mentioned related technologies, the applicant believes that when a sand and water separation device of a sewage pump station is working, sand and water are added to the barrel inside the box, and a vortex is formed by stirring by the rotating shaft. The sand and gravel in the sand and water will be concentrated by the vortex and fall to the bottom, and be discharged outward by the shaftless spiral blades. However, when the actual sewage station treats sand and water, the sand and water treatment is carried out continuously, and the continuous addition of a large amount of sand and water falling from the top into the inner barrel will destroy the formation of the vortex, resulting in a decrease in the rotation speed of the vortex, reducing the speed at which sand and gravel gather and settle to the center, thereby affecting the speed of separating a large amount of sand and water for a long time. Utility Model Content

[0005] The purpose of the utility model is to provide a sand-water separation device for a sewage pump station to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sand-water separation device for a sewage pump station, comprising a base frame, an outer pipe, a separation pipe, and a drive assembly.

[0007] The outer wall of the outer tube is welded to the top of the bottom frame; a drain pipe is welded to the outer wall of the bottom of the outer tube, and the drain pipe is communicated with the inside of the outer tube;

[0008] The outer wall of the separation tube is rotatably connected to the inside of the outer tube, and a part of the separation tube extends out of the outer tube; a filter hole is opened on the inner wall of the separation tube, and the filter hole is opened on the separation tube located inside the outer tube; spiral blades are also welded and arranged on the inner wall of the separation tube;

[0009] The driving assembly is arranged on the base frame and is in driving connection with the portion of the separation tube extending out of the outer tube through a transmission mechanism, so as to drive the separation tube to rotate in the outer tube.

[0010] By adopting the above technical solution, the driving component is assembled on the base frame, and the driving component can drive the extended part of the separation pipe to rotate. When sand and water are continuously added into the separation pipe, the sewage flows into the outer pipe through the filter holes and is discharged from the drain pipe, while the sand and gravel filtered by the filter holes are moved forward by the spiral blades and discharged from the other end of the separation pipe. The device separates sand and water by rotating the separation pipe to separate sewage and sand and gravel, reducing the influence of continuous addition of sand and water on separation, thereby maintaining a relatively stable separation speed to process sand and water, so as to ensure daily sand and water treatment in the sewage station.

[0011] Preferably, teeth are welded circumferentially on the outer wall of one end of the separation tube extending out of the outer tube;

[0012] The driving assembly comprises a fixing frame, a sprocket shaft, a transmission gear, a motor and a chain.

[0013] One end of the fixing frame is welded to one side of the base frame; the two ends of the sprocket shaft are rotatably connected to the outer tube and the fixing frame respectively; the transmission gear is clamped on the outer wall of the sprocket shaft, and one side of the transmission gear is meshed with the teeth; the motor is fixed to the bottom of the base frame through a mounting seat, and a sprocket is fixed on the motor shaft; the two ends of the chain are meshed on the sprocket shaft and the sprocket of the motor.

[0014] By adopting the above technical solution, a gear structure can be formed by welding circumferential teeth on the outer wall of the separation tube. The motor provides power to drive the chain to make the sprocket shaft rotate rapidly on the fixed frame. The sprocket shaft also drives the transmission gear to rotate together. The transmission gear meshes with the gear structure formed by the rotating teeth, thereby causing the separation tube to rotate together to separate sand and water.

[0015] Preferably, a sand-water separation device for a sewage pumping station also includes: a pipe cover and a buckle.

[0016] A tube cover, one side of which is rotatably connected to the top of the outer tube through a hinge;

[0017] The buckle is fixed on the outer wall of the outer tube by screws, and the buckle can be buckled on the tube cover.

[0018] By adopting the above technical solution, a rotatable tube cover is installed on the top of the outer tube and fastened with a buckle. After the filter hole separates sand and water for a long time, the tube cover can be opened to facilitate maintenance and cleaning of the outer wall of the separation tube to ensure the normal filtering and separation efficiency of the filter hole.

[0019] Preferably, sealing strips are attached to the four edges of the tube cover, and the sealing strips on the tube cover can fit tightly with the top of the outer tube.

[0020] By adopting the above technical solution, by sticking sealing strips around the pipe cover, it can fit tightly with the outer pipe after closing to ensure its sealing, avoid sewage flowing out of the gaps generated after closing to pollute the environment, and improve the sealing inside the outer pipe.

[0021] Preferably, a circular ring plate is welded to an opening at one end of the separation tube, and a central opening of the circular ring plate is smaller than an opening at the other end of the separation tube.

[0022] By adopting the above technical solution, by inserting the water pipe of the sewage station into the separation pipe with one end of the circular ring plate, the added sand and water will enter the separation pipe and be blocked by the circular ring plate to avoid flowing out from the end where the sand and water are added. At the same time, the sand and gravel can be smoothly discharged from the interior of the separation pipe by the spiral blades after being filtered through the filter holes.

[0023] Preferably, the filter holes are opened on the separation tube inside the outer tube.

[0024] By adopting the above technical solution, filtering holes are opened on the outer wall of the separation tube to ensure filtering inside the outer tube, separate sand and water, and avoid sewage leakage from the filtering holes into the environment to cause pollution.

[0025] Preferably, bearings are clamped on the fixing frame and the outer tube, and two ends of the sprocket shaft are respectively inserted into the inner walls of the bearings.

[0026] By adopting the above technical solution, installing the sprocket shaft through bearings can reduce the resistance on both ends of the rotation, improve the efficiency of the sprocket shaft in transmitting the motor power to the separation tube, reduce the load on the motor when it is working, and increase the service life of the motor.

[0027] Compared with the prior art, the beneficial effects of the utility model are:

[0028] (1) The motor can rotate the separation tube under the action of the chain, sprocket shaft and transmission gear. The filter holes inside the separation tube separate the sand and water. The sewage is filtered to the outer tube and discharged from the drain pipe. The sand and gravel are pushed out by the rotating spiral blades. During the separation process, a large amount of sand and water can be added continuously for separation, which reduces the impact of the continuous addition of sand and water on the separation, thereby maintaining a relatively stable separation speed to treat the sand and water, so as to ensure the daily sand and water treatment of the sewage station.

[0029] (2) By installing a rotatable pipe cover on the top of the outer pipe and fastening it with a buckle, the pipe cover can be opened after the filter hole separates sand and water for a long time, so as to facilitate the maintenance and cleaning of the outer wall of the separation pipe to ensure the normal filtering and separation efficiency of the filter hole.

At the same time, the sand and gravel can be smoothly discharged from the interior of the separation tube 3 by the spiral blade 5 after filtering through the filter hole 4. The filter hole 4 is opened on the separation tube 3 inside the outer tube 2. By opening the filter hole 4 inside the separation tube 3, it is ensured that the sand and water are filtered inside the separation tube 3 to separate the sand and water.

Bearings are clamped on the fixing frame 7 and the outer tube 2, and the two ends of the sprocket shaft 8 are respectively inserted into the inner wall of the bearing. The sprocket shaft 8 is installed by the bearing to reduce the resistance of the two ends of the rotation, improve the efficiency of the sprocket shaft 8 transmitting the power of the motor 10 to the separation tube 3, reduce the load of the motor 10 when working, and improve the service life of the motor 10.

[0054] Working principle: When in use, first insert the opening of the separation tube 3 with one end of the circular ring plate into the pipe mouth for conveying sand and water to add sand and water inward, and place the sand and gravel conveyor under the outlet of the other end. The motor 10 drives the sprocket shaft 8 to rotate under the transmission of the chain 11, and the transmission gear 9 on the sprocket shaft 8 rotates to drive the separation tube 3 to rotate. When sand and water are continuously added to the separation tube 3, the sewage flows into the outer tube 2 through the filter hole 4 and is discharged from the drain pipe 12. The sand and gravel filtered by the filter hole 4 are moved forward by the rotating spiral blade 5, discharged from the other end of the separation tube 3, fall onto the conveyor and are transported to the sand and gravel collection pit.
