[0008] A water-soluble monoammonium phosphate filtrate pump includes a filtrate pump for extracting and filtering water-soluble monoammonium phosphate; and a filter assembly disposed at the extraction end of the filtrate pump for filtering the water-soluble monoammonium phosphate. The filter assembly includes a treatment tank, a drive wheel, a cleaning brush, a filter cartridge, and a drive motor. The treatment tank is fixedly connected to the extraction end of the filtrate pump, the drive motor is installed in a corresponding position, the drive wheel is rotatably connected to the treatment tank, and there is a transmission connection between the drive motor and the drive wheel. The filter cartridge is installed inside the treatment tank, and an array of cleaning brushes is disposed on the drive wheel, with the drive wheel abutting against the wall of the filter cartridge.

[0009] In a preferred embodiment of this utility model, each of the cleaning brushes is fixedly connected to the transmission wheel, the wall surface of the cleaning brush is chamfered, and support rods are arranged in an array on the transmission wheel, with each support rod fixedly connected to the transmission wheel.

[0010] In a preferred embodiment of the present invention, each of the support rods is provided with an array of guide blocks, each guide block is inclined, and the bottom of each cleaning brush and support rod is fixedly connected to the same ring block.

[0011] In a preferred embodiment of this utility model, each of the cleaning brushes and support rods is staggered, and the ring block rotates with the inner wall of the treatment tank.

[0012] In a preferred embodiment of this utility model, a mounting base is rotatably connected to the transmission wheel, and a filter cartridge is connected to the mounting base by fasteners. An inlet pipe is fixedly connected to the upper end of the mounting base.

[0013] In a preferred embodiment of this utility model, the mounting base is provided with abutment rods, and each abutment rod is provided with an array of guide rings, each guide ring being fixedly connected to the corresponding abutment rod.

[0014] In a preferred embodiment of the present invention, each of the guide rings is annular in shape, and an annular protrusion is provided in the middle of each guide ring. The annular protrusions are arranged opposite each other, and there is a gap between the annular protrusions.

[0015] In a preferred embodiment of this utility model, the processing tank is provided with an array of support rods, each support rod is fixedly connected to the processing tank, a bracket is slidably connected to the support rod, an abutment roller is rotatably connected to the bracket, a spring is provided between each support rod and the bracket, and the end of each spring is fixedly connected to the corresponding support rod and bracket respectively.

[0016] In a preferred embodiment of this utility model, the bottom of the drive motor is fixedly connected to a base, and a transmission belt is used to drive the drive motor and the transmission wheel.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. This water-soluble ammonium phosphate filtrate pump, through the cooperation of internal components of the filter assembly, drives the cleaning brush to rotate and continuously rub against the wall of the filter cartridge. During the friction, the impurities accumulated on the filter cartridge are removed, preventing the impurities from clogging the filter cartridge and affecting the filtration effect and filtration rate.

[0019] 2. This water-soluble ammonia phosphate filtrate pump, during the rotation of the transmission wheel, drives the support rod to rotate, and the support rod drives the guide ring to rotate, guiding the water-soluble ammonia phosphate liquid inside the treatment tank. In the guiding process, the flow velocity of the water-soluble ammonia phosphate after filtration is increased, forming a vortex. The filtered water-soluble ammonia phosphate liquid is quickly discharged through the vortex, thereby improving the filtration rate.

[0020] 3. This water-soluble ammonia phosphate filtrate pump, when the water-soluble ammonia phosphate liquid passes through the narrow gap between the annular protrusions between the guide rings, local turbulence is generated due to shearing action. The generation of turbulence increases the flow rate of the water-soluble ammonia phosphate liquid, thereby improving the filtration effect. In addition, the annular protrusions disperse the water-soluble ammonia phosphate liquid, ensuring uniform contact between the water-soluble ammonia phosphate liquid and the filter cartridge wall. Under the action of providing acceleration force, the water-soluble ammonia phosphate liquid fully contacts the filter cartridge wall, thereby improving the filtration effect.

[0021] 4. This water-soluble ammonium phosphate filtrate pump applies force to the bottom of the filter cartridge via an abutment roller, which supports the filter cartridge and prevents it from loosening and detaching from the mounting base under the impact of liquid flow. Furthermore, the roller-shaped design of the abutment roller reduces wear on the bottom of the filter cartridge during installation and movement, thus preventing damage to the bottom of the filter cartridge from affecting the filtration effect.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0031] Please see Figure 1-5 A water-soluble monoammonium phosphate filtrate pump includes a filtrate pump 21 for drawing water-soluble monoammonium phosphate for filtration; and a filtration assembly disposed at the extraction end of the filtrate pump 21 for filtering the water-soluble monoammonium phosphate. The filtration assembly includes a treatment tank 2, a drive wheel 3, cleaning brushes 31, a filter cartridge 5, and a drive motor 11. The treatment tank 2 is fixedly connected to the extraction end of the filtrate pump 21, the drive motor 11 is installed in a corresponding position, the drive wheel 3 is rotatably connected to the treatment tank 2, and the drive motor 11 is connected to the drive wheel 3 for transmission. The filter cartridge 5 is installed inside the treatment tank 2, and the cleaning brushes 31 are arranged in an array on the drive wheel 3, with the drive wheel 3 abutting against the wall of the filter cartridge 5. Through the cooperation of the internal components of the filtration assembly, the cleaning brushes 31 are driven to rotate and continuously rub against the wall of the filter cartridge 5, removing impurities accumulated on the filter cartridge 5 during friction, preventing impurities from clogging the filter cartridge 5 and affecting the filtration effect and filtration rate.

[0032] Each cleaning brush 31 is fixedly connected to a drive wheel 3. The wall surface of the cleaning brush 31 is chamfered. Support rods 32 are arranged in an array on the drive wheel 3, and each support rod 32 is fixedly connected to the drive wheel 3. Guide blocks 33 are arranged in an array on each support rod 32, and each guide block 33 is inclined. The bottom of each cleaning brush 31 and support rod 32 is fixedly connected to the same ring block 34. Each cleaning brush 31 and support rod 32 are staggered, and the ring block 34 rotates against the inner wall of the treatment tank 2. The drive wheel 3 rotates, driving the cleaning brush 31 to rotate. During rotation, the filter element 31 continuously rubs against the filter cartridge 5, removing impurities accumulated on the filter cartridge 5 and preventing it from clogging and affecting the filtration efficiency and rate. Furthermore, as the drive wheel 3 rotates, it drives the support rod 32 to rotate, which in turn drives the guide block 33 to rotate, guiding the water-soluble ammonium phosphate liquid inside the treatment tank 2. This increased flow velocity of the filtered water-soluble ammonium phosphate liquid during the guiding process, creating a vortex. This vortex then rapidly discharges the filtered water-soluble ammonium phosphate liquid, improving the filtration rate.

[0033] The drive wheel 3 is rotatably connected to a mounting base 4. The mounting base 4 is connected to a filter cartridge 5 by fasteners, including but not limited to bolts. The upper end of the mounting base 4 is fixedly connected to an inlet pipe 41. The mounting base 4 is surrounded by abutment rods 43. Each abutment rod 43 is arranged in an array of guide rings 42. Each guide ring 42 is fixedly connected to the corresponding abutment rod 43. Each guide ring 42 is annular in shape. Each guide ring 42 has an annular protrusion in the middle. Each annular protrusion is arranged opposite to each other and there is a gap between the annular protrusions. After the corresponding filter cartridge 5 is installed between the mounting base 4 and the fasteners, the mounting base 4 is rotatably installed between the drive wheel 3.

[0034] It is worth noting that after the processing tank 2, transmission wheel 3, mounting base 4 and other components are assembled, the processing tank 2 and transmission wheel 3 are fixed to the same plane to ensure that the positions of the processing tank 2 and mounting base 4 remain unchanged during the operation of this device. In order to intuitively show the internal structure, this solution is not shown in the figure and will not be described in detail here.

[0035] Water-soluble monoammonium phosphate liquid enters the filter cartridge 5 through the inlet pipe 41. Under the action of the filtrate pump 21, when the water-soluble monoammonium phosphate liquid passes through the narrow gap between the annular protrusions between the guide rings 42, local turbulence is generated due to shearing action. The generation of turbulence increases the flow rate of the water-soluble monoammonium phosphate liquid, thereby improving the filtration effect. In addition, the annular protrusions disperse the water-soluble monoammonium phosphate liquid, ensuring uniform contact between the water-soluble monoammonium phosphate liquid and the wall surface of the filter cartridge 5. Under the action of the acceleration force, the water-soluble monoammonium phosphate liquid fully contacts the wall surface of the filter cartridge 5, thereby improving the filtration effect.

[0036] The treatment tank 2 is equipped with an array of support rods 22, each of which is fixedly connected to the treatment tank 2. A bracket 24 is slidably connected to the support rod 22, and an abutment roller 25 is rotatably connected to the bracket 24. A spring 23 is provided between each support rod 22 and the bracket 24. The end of each spring 23 is fixedly connected to the corresponding support rod 22 and bracket 24. When the bottom of the filter cartridge 5 contacts the abutment roller 25, the abutment roller 25 presses down on the bracket 24 and the spring 23. The spring 23 is deformed and generates an opposite force, which is applied to the bracket 24 and the abutment roller 25. The force is applied to the bottom of the filter cartridge 5 through the abutment roller 25, which supports the filter cartridge 5 and prevents the filter cartridge 5 from loosening and detaching from the mounting base 4 under the impact of liquid flow. In addition, the roller-shaped design of the abutment roller 25 reduces the wear on the bottom of the filter cartridge 5 during installation and contact with the abutment roller 25, and avoids damage to the bottom of the filter cartridge 5, which would affect the filtration effect.

[0037] The drive motor 11 is fixedly connected to the base 1 at its bottom. A transmission belt 12 is connected between the drive motor 11 and the transmission wheel 3. The output end of the drive motor 11 drives the transmission belt 12 to rotate, and the transmission belt 12 drives the transmission wheel 3 to rotate. The rotation of the transmission wheel 3 drives the internal components to work.

[0038] Working principle: The output of the drive motor 11 drives the transmission belt 12 to rotate, which in turn drives the transmission wheel 3 to rotate. The rotation of the transmission wheel 3 drives the internal components to work. After the corresponding filter cartridge 5 is installed between the fastener and the mounting base 4, the mounting base 4 is rotated between the transmission wheel 3. Water-soluble ammonia phosphate liquid enters the filter cartridge 5 through the inlet pipe 41. Under the action of the filtrate pump 21, when the water-soluble ammonia phosphate liquid passes through the narrow gap between the annular protrusions between the guide rings 42, local turbulence is generated due to shearing action. The generation of turbulence increases the flow rate of the water-soluble ammonia phosphate liquid, thereby improving the filtration effect. In addition, the annular protrusions disperse the water-soluble ammonia phosphate liquid, ensuring that the water-soluble ammonia phosphate liquid is in uniform contact with the wall surface of the filter cartridge 5. Under the action of providing acceleration force, the water-soluble monoammonium phosphate liquid is fully contacted with the wall surface of the filter cartridge 5, improving the filtration effect. The drive wheel 3 drives the cleaning brush 31 to rotate during rotation. The cleaning brush 31 continuously rubs against the filter cartridge 5 during rotation, removing the impurities accumulated on the filter cartridge 5 during friction, preventing impurities from clogging the filter cartridge 5 and affecting the filtration effect and filtration rate. During the rotation of the drive wheel 3, the drive wheel 3 drives the support rod 32 to rotate. The support rod 32 drives the guide block 33 to rotate, guiding the water-soluble monoammonium phosphate liquid inside the treatment tank 2. In the guidance, the flow velocity of the water-soluble monoammonium phosphate after filtration is increased, forming a vortex. The filtered water-soluble monoammonium phosphate liquid is quickly discharged through the vortex, improving the filtration rate.
