However, after the water pressure regulating device is adjusted, the adjusting bolts cannot be fixed. After being impacted by water for a long time, the pressure regulating bolts will inevitably become slightly loose.

[0017] To achieve the above object, the present invention also provides the following technical solution: a method for using a constant pressure water treatment device, according to the constant pressure water treatment device, the steps are: (1) First, the staff discharges the sewage into the treatment pool; (2) When the sewage enters the treatment tank, the filter plate performs preliminary filtration on the sewage; (3) Then, the staff put the medicine into the treatment pool; (4) Before the drug is administered, the motor is started to drive the screw to rotate. During the rotation of the screw, the threads on the surface drive the slider to slide; (5) Because the gear and the rack mesh with each other, when the slider moves, the gear and the stirring rod will rotate under the action of the rack, thereby improving the dispersion effect of the drug; (6) When the sewage is discharged into the treatment tank for a period of time, the filter plate needs to be treated. The staff uses the handle to take the filter plate out of the treatment tank 1, and then treats or replaces the filter plate; (7) In the process of step (5), when the sewage in the treatment pool reaches a certain height, the water level sensor detects that the water level meets the preset height, and the water pump starts; (8) The water pump sends the treated sewage in the treatment tank to the constant pressure device; (9) Water flows from the input pipe into the main pipe. At this time, the water flows to impact the closing pad, which opens the closing pad and moves upward, driving the slide rod. The slide rod then slides upward in the water pressure regulating screw, and the water flows out from the output pipe. (10) The outflowing water passes through a one-way valve and enters the filtering device for filtration, and then the filtered water that meets the requirements is discharged; (11) When the water flow is output through the constant pressure device, the staff can observe the water pressure in the main pipe in real time through the water pressure gauge; (12) When the water pressure is too high and needs to be reduced: turn the operating handle clockwise, the operating handle drives the telescopic rod to rotate, the telescopic rod drives the swivel to rotate, and the operating handle drives the water pressure adjustment screw at the bottom to rotate. When the water pressure adjustment screw rotates, it drives the extrusion plate at the bottom to move downward. The extrusion plate squeezes the spring to reduce the water pressure. When the water pressure displayed on the water pressure gauge meets the requirements, stop the operation; (13) When the water pressure is too low and needs to be increased: by turning the operating handle counterclockwise, the operating handle drives the telescopic rod to rotate, the telescopic rod drives the swivel to rotate, and at the same time the operating handle drives the water pressure regulating screw at the bottom to rotate. When the water pressure regulating screw rotates, the extrusion plate at the bottom moves upward. At this time, the spring 8 rebounds and the water pressure is increased. When the water pressure displayed on the water pressure gauge meets the requirements, stop the operation; (14) After the water pressure is adjusted according to step (12) or (13), in order to make the water pressure more stable, the hand wheel is turned to drive the locking screw to rotate. The locking screw moves inward while rotating and drives the connecting block to move. The movement of the connecting block drives the T-shaped slider, and the T-shaped slider slides on the L-shaped seat. The movement of the connecting block drives the fixing ring, so that the rubber ball on the fixing ring tightly squeezes the rotating ring, effectively preventing the water pressure adjustment screw from moving slightly up or down due to long-term water impact, thereby causing the water pressure to change and resulting in unstable water pressure.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention cooperates with the treatment tank, the motor, the displacement assembly and the stirring structure so that when the device is in use, the stirring structure can be used to stir the treatment tank, so that the sprayed medicine can be distributed more evenly, thereby solving the problem of uneven drug dispersion in existing devices and reduced treatment effect.

[0019] 2. The present invention cooperates with the driving mechanism and the filter component so that the device can preliminarily filter the impurities in the sewage when in use, and the filter component can be easily disassembled and cleaned, thereby increasing the practicality of the device; 3. The locking screw is driven to rotate by the hand wheel, and the locking screw moves inward while rotating, and drives the connecting block to move. The movement of the connecting block drives the T-shaped slider, and the T-shaped slider slides on the L-shaped seat. The movement of the connecting block drives the fixing ring, so that the rubber ball on the fixing ring tightly squeezes the swivel, so that the water pressure adjusting bolt can be fixed, the stability of the water pressure is improved, and it is effectively prevented that the water pressure adjusting screw will move slightly up or down due to long-term water impact, thereby causing the water pressure to change and resulting in unstable water pressure.

[0020] 4. By turning the operating handle clockwise, the operating handle drives the telescopic rod to rotate, the telescopic rod drives the swivel to rotate, and the operating handle drives the water pressure adjusting screw at the bottom to rotate. When the water pressure adjusting screw rotates, the extrusion plate at the bottom moves downward, and the extrusion plate squeezes the spring to reduce the water pressure; by turning the operating handle counterclockwise, the operating handle drives the telescopic rod to rotate, the telescopic rod drives the swivel to rotate, and the operating handle drives the water pressure adjusting screw at the bottom to rotate. When the water pressure adjusting screw rotates, the extrusion plate at the bottom moves upward, and the spring rebounds to increase the water pressure, so that the water pressure can be easily adjusted and used; 5. Through the cooperation of the water level sensor and the water pump, the water level in the treatment pool can be monitored in real time to prevent the water level from being too low and affecting the stable output of the water pressure at the constant pressure device, and to avoid the situation where the water pump is overloaded due to lack of water; 6. The one-way valve is set to prevent the water pressure in the filter device from flowing back to the constant pressure device after there is no water in the treatment pool and the water pump, so that the water flows in one direction and cross contamination is avoided.

A sealing ring 221 is arranged at the bottom of the closing pad 207, and the sealing ring 221 matches the annular groove 220. After the water is cut off, the closing pad 207 is subjected to the elastic force of the spring 2088 and is inserted into the closing seat 219 to complete the sealing. Through the technical solution of the present application, in actual use, the method for using the constant pressure water treatment device comprises the following steps: (1) First, the staff discharges the sewage into the treatment pool 11; (2) When the sewage enters the treatment tank 11, the filter plate 1601 performs preliminary filtration on the sewage; (3) Then, the staff puts drugs into the treatment pool 11; (4) Before the drug is administered, the motor 12 is started to drive the screw 1301 to rotate. During the rotation of the screw 1301, the threads on the surface drive the slider 1401 to slide; (5) Since the gear 1501 and the rack 1502 are meshed with each other, when the slider 1401 moves, the gear 1501 and the stirring rod 1402 will rotate under the action of the rack 1502, thereby improving the dispersion effect of the drug; (6) When the sewage is discharged into the treatment tank 11 for a period of time, the filter plate 1601 needs to be processed. The staff uses the handle 1602 to take the filter plate 1601 out of the treatment tank 111, and then processes or replaces the filter plate 1601; (7) In the process of step (5), when the sewage in the treatment tank 11 reaches a certain height, the water level sensor detects that the water level meets the preset height, and the water pump 4 starts; (8) The water pump 4 delivers the treated wastewater in the treatment tank 11 to the constant pressure device 2; (9) Water flows from the input pipe 202 into the main pipe 201. At this time, the water flows to impact the closing pad 207. After the closing pad 207 is opened, the closing pad 207 moves upward, driving the slide bar 206. The slide bar 206 then slides upward in the water pressure regulating screw 204, and the water flows out from the output pipe 203. (10) The outflowing water flows through the one-way valve 5 and enters the filtering device 3 for filtration, and then the filtered water that meets the requirements is discharged; (11) When the water flow is output through the constant pressure device 2, the staff can observe the water pressure in the main pipe 201 in real time through the water pressure gauge; (12) When the water pressure is too high and needs to be reduced: by rotating the operating handle 212 clockwise, the operating handle 212 drives the telescopic rod 211 to rotate, and the telescopic rod 211 drives the swivel 210 to rotate. At the same time, the operating handle 212 drives the water pressure regulating screw 204 at the bottom to rotate. When the water pressure regulating screw 204 rotates, it drives the squeezing plate 205 at the bottom to move downward. The squeezing plate 205 squeezes the spring 208 to reduce the water pressure. When the water pressure displayed on the water pressure gauge meets the requirements, stop the operation. (13) When the water pressure is too low and needs to be increased: by rotating the operating handle 212 counterclockwise, the operating handle 212 drives the telescopic rod 211 to rotate, and the telescopic rod 211 drives the swivel 210 to rotate. At the same time, the operating handle 212 drives the water pressure regulating screw 204 at the bottom to rotate. When the water pressure regulating screw 204 rotates, it drives the squeezing plate 205 at the bottom to move upward. At this time, the spring 2088 rebounds to increase the water pressure. When the water pressure displayed on the water pressure gauge meets the requirements, stop the operation. (14) After the water pressure is adjusted according to step (12) or (13), in order to make the water pressure more stable, the hand wheel 218 is turned, and the hand wheel 218 drives the locking screw 214 to rotate. The locking screw 214 moves inward while rotating and drives the connecting block 215 to move. The movement of the connecting block 215 drives the T-shaped slider 222, and the T-shaped slider 222 slides on the L-shaped seat 213. The movement of the connecting block 215 drives the fixing ring 216, so that the rubber ball 217 on the fixing ring 216 tightly squeezes the rotating ring 210, effectively preventing the water pressure adjustment screw 204 from moving slightly up or down due to long-term water impact, thereby causing the water pressure to change, resulting in unstable water pressure.

13. A method for using a constant pressure water treatment device, characterized in that: The constant pressure water treatment device according to any one of claims 1 to 12, wherein the steps are: (1) First, the staff discharges the sewage into the treatment pool (11); (2) When the sewage enters the treatment tank (11), the filter plate (1601) performs preliminary filtration on the sewage; (3) Then, the staff puts the medicine into the treatment pool (11); (4) Before the drug is administered, the motor (12) is started to drive the screw (1301) to rotate. During the rotation of the screw (1301), the threads on the surface drive the slider (1401) to slide; (5) Since the gear (1501) and the rack (1502) mesh with each other, when the slider (1401) moves, the gear (1501) and the stirring rod (1402) rotate under the action of the rack (1502), thereby improving the dispersion effect of the drug; (6) When sewage is discharged into the treatment tank (11) for a period of time, the filter plate (1601) needs to be processed. The staff uses the handle (1602) to take the filter plate (1601) out of the treatment tank (11) 1, and then processes or replaces the filter plate (1601); (7) In the process of step (5), when the sewage in the treatment tank (11) reaches a certain height, the water level sensor detects that the water level meets the preset height, and the water pump (4) starts; (8) The water pump (4) delivers the treated wastewater in the treatment tank (11) to the constant pressure device (2); (9) Water flows from the input pipe (202) into the main pipe (201). At this time, the water flows impact the closing pad (207). After the closing pad (207) is opened, the closing pad (207) moves upward, driving the slide bar (206). The slide bar (206) then slides upward in the water pressure regulating screw (204), and the water flows out from the output pipe (203). (10) The outflowing water flows through the one-way valve (5) into the filtering device (3) for filtration, and then the filtered water that meets the requirements is discharged; (11) When the water flow is output through the constant pressure device (2), the staff can observe the water pressure in the main pipe (201) in real time through the water pressure gauge; (12) When the water pressure is too high and needs to be reduced: by rotating the operating handle (212) clockwise, the operating handle (212) drives the telescopic rod (211) to rotate, and the telescopic rod (211) drives the rotating ring (210) to rotate. At the same time, the operating handle (212) drives the water pressure regulating screw (204) at the bottom to rotate. When the water pressure regulating screw (204) rotates, it drives the squeezing plate (205) at the bottom to move downward. The squeezing plate (205) squeezes the spring (208) to reduce the water pressure. When the water pressure displayed on the water pressure gauge meets the requirements, stop the operation. (13) When the water pressure is too low and needs to be increased: by rotating the operating handle (212) counterclockwise, the operating handle (212) drives the telescopic rod (211) to rotate, and the telescopic rod (211) drives the rotating ring (210) to rotate. At the same time, the operating handle (212) drives the water pressure regulating screw (204) at the bottom to rotate. When the water pressure regulating screw (204) rotates, it drives the squeezing plate (205) at the bottom to move upward. At this time, the spring (208) 8 rebounds to increase the water pressure. When the water pressure displayed on the water pressure gauge meets the requirements, the operation is stopped. (14) After the water pressure is adjusted according to step (12) or (13), in order to make the water pressure more stable, the hand wheel (218) is rotated, and the hand wheel (218) drives the locking screw (214) to rotate. The locking screw (214) moves inward while rotating and drives the connecting block (215) to move. The connecting block (215) moves and drives the T-shaped slider (222). The T-shaped slider (222) slides on the L-shaped seat (213). The connecting block (215) moves and drives the fixing ring (216) so that the rubber ball (217) on the fixing ring (216) tightly squeezes the rotating ring (210), effectively preventing the water pressure adjustment screw (204) from moving slightly up or down due to long-term water impact, thereby causing the water pressure to change and resulting in unstable water pressure.
