Description

Technical Field

[0001] This utility model relates to the technical field of pressure curved screen cleaning devices, specifically a pressure curved screen cleaning nozzle. Background Technology

[0002] A pressure curved screen is a filtration device used for solid-liquid separation. Its screen is curved or arc-shaped and operates within a closed pressure vessel. By applying pressure, the liquid is forced through the screen, while solid particles are trapped. This design improves filtration efficiency and throughput, making it suitable for industrial applications requiring high-pressure operation, such as papermaking, food processing, and wastewater treatment.

[0003] The pressure curved screen cleaning nozzle is a device specifically designed for cleaning curved screens. It uses high-pressure water jets to impact the screen surface, removing accumulated impurities and blockages, ensuring the screen's high-efficiency filtration performance. This nozzle is typically equipped with multiple adjustable-angle high-pressure nozzles and can fully cover the screen through rotation or reciprocating motion. It is widely used in industries such as papermaking, food processing, and wastewater treatment.

[0004] Existing pressure curved screen cleaning nozzles typically lack pressure regulation capabilities, resulting in unstable output pressure during the cleaning process. Due to this instability, some areas may be subjected to excessively high pressure and over-cleaned, while other areas may be under-cleaned due to insufficient pressure, leading to poor cleaning performance. Utility Model Content

[0005] The purpose of this invention is to provide a pressure curved screen cleaning nozzle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure curved screen cleaning spray pipe, comprising a three-way pipe, a pressure control mechanism fixedly connected to the top of the three-way pipe, a pressure stabilizing mechanism fixedly connected to one side of the three-way pipe, a connecting pipe fixedly connected to one side of the three-way pipe, and a nozzle mechanism fixedly connected to one end of the connecting pipe. The pressure control mechanism includes a first mounting shell, an inlet at the bottom of the first mounting shell, a baffle movably mounted on the top of the inlet, a turntable rotatably mounted on the top of the first mounting shell, a screw threadedly connected to the inside of the turntable, a mounting bracket fixedly connected to the bottom of the screw, the mounting bracket slidably mounted inside the first mounting shell, the baffle slidably mounted on the bottom of the mounting bracket, a first spring fixedly mounted on the bottom of the mounting bracket, the first spring being disposed on the top of the baffle, and an outlet at one side of the first mounting shell.

[0007] Preferably, a plurality of control levers are fixedly installed on the outer wall of the turntable.

[0008] Preferably, a water pressure sensor is fixedly installed on one side of the connecting pipe.

[0009] Preferably, a flow sensor is fixedly installed on one side of the connecting pipe.

[0010] Preferably, the voltage stabilizing mechanism includes a second mounting housing, a mounting column is slidably mounted inside the second mounting housing, a sliding plate is fixedly mounted at the bottom of the mounting column, the sliding plate is slidably mounted inside the second mounting housing, and a second spring is sleeved on the outer wall of the mounting column, the second spring being disposed inside the second mounting housing.

[0011] Preferably, a sealing ring is fixedly installed on the outer wall of the slide.

[0012] Preferably, the nozzle mechanism includes a third mounting housing, the interior of which is provided with a main channel and a secondary channel, the secondary channel being located on one side of the main channel, and a one-way valve being fixedly connected to one end of the secondary channel.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the pressure curved screen cleaning nozzle;

[0014] 1. The first spring provides a downward pressure to the baffle towards the top of the inlet, ensuring that water can only enter the first mounting shell when the water pressure is greater than the spring force of the first spring. The water then flows out through the outlet and is sprayed out through the connection pipe and nozzle mechanism to clean the pressure screen. This achieves the purpose of limiting the minimum pressure of the output water flow and preventing the output water pressure from being too low to effectively clean the screen. During this process, the cooperation between the turntable, screw, and mounting bracket allows the operator to adjust the tension of the first spring by rotating the turntable, thereby changing the output threshold of the pressure control mechanism.

[0015] 2. The second spring provides a downward pressure to the slide plate, causing a portion of the water flow at the front end of the pressure stabilizing mechanism to flow into the second mounting housing when the pressure is too high, thus reducing the internal water pressure. After the pressure decreases, the water is squeezed back into the three-way pipe by the slide plate, increasing the internal water pressure. This balances the water flow pressure at the front end of the pressure control mechanism, ensuring the stability of the water flow output from the nozzle mechanism. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This utility model provides a technical solution: a pressure curved screen cleaning spray pipe, including a three-way pipe 1, a pressure control mechanism 2 fixedly connected to the top of the three-way pipe 1, a pressure stabilizing mechanism 3 fixedly connected to one side of the three-way pipe 1, a connecting pipe 4 fixedly connected to one side of the three-way pipe 1, and a nozzle mechanism 7 fixedly connected to one end of the connecting pipe 4. The pressure control mechanism 2 includes a first mounting shell 201, an inlet 202 opened at the bottom of the first mounting shell 201, a baffle 203 movably mounted on the top of the inlet 202, a turntable 204 rotatably mounted on the top of the first mounting shell 201, a screw 205 threadedly connected inside the turntable 204, and a mounting bracket 206 fixedly connected to the bottom of the screw 205. The mounting bracket 206 is slidably installed inside the first mounting shell 201. The baffle 203 is slidably installed at the bottom of the mounting bracket 206. A first spring 207 is fixedly installed at the bottom of the mounting bracket 206. The first spring 207 is located at the top of the baffle 203. A liquid outlet 208 is opened on one side of the first mounting shell 201. Several operating levers 209 are fixedly installed on the outer wall of the turntable 204. The operating levers 209 facilitate the user to rotate the turntable 204. A water pressure sensor 5 is fixedly installed on one side of the connecting pipe 4 to detect the water pressure inside the connecting pipe 4. A flow sensor 6 is fixedly installed on one side of the connecting pipe 4 to detect the flow rate inside the connecting pipe 4.

[0023] The specific implementation method is as follows: the first spring 207 provides a downward pressure to the baffle 203 towards the top of the inlet 202, so that the water flow inside the inlet 202 can only enter the interior of the first mounting shell 201 when the water pressure is greater than the elastic force of the first spring 207, and then flow out through the outlet 208. Then, through the cooperation between the connecting pipe 4 and the nozzle mechanism 7, the water is sprayed to clean the pressure curved screen, thereby achieving the purpose of limiting the minimum pressure of the output water flow and preventing the output water pressure from being too low to effectively clean. During this process, through the cooperation between the turntable 204, the screw 205, and the mounting bracket 206, the operator can adjust the tension of the first spring 207 by rotating the turntable 204, thereby changing the output threshold of the pressure control mechanism 2.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a pressure curved screen cleaning nozzle, wherein the pressure stabilizing mechanism 3 includes a second mounting shell 301, a mounting column 302 is slidably mounted inside the second mounting shell 301, a sliding plate 303 is fixedly mounted at the bottom of the mounting column 302, the sliding plate 303 is slidably mounted inside the second mounting shell 301, a second spring 304 is sleeved on the outer wall of the mounting column 302, the second spring 304 is disposed inside the second mounting shell 301, and a sealing ring 305 is fixedly mounted on the outer wall of the sliding plate 303, the sealing ring 305 ensuring the sliding plate 303 is securely mounted. 3. The sealing between the second mounting housing 301 prevents leakage. The nozzle mechanism 7 includes a third mounting housing 701. The third mounting housing 701 has a main channel 702 and a secondary channel 703. The secondary channel 703 is located on one side of the main channel 702. One end of the secondary channel 703 is fixedly connected to a one-way valve 704. The main channel 702 serves as the main output channel, and the cooperation between the secondary channel 703 and the one-way valve 704 facilitates the user to inject auxiliary cleaning agent into the main channel 702, thereby improving cleaning efficiency.

[0025] The specific implementation method is as follows: the second spring 304 provides a downward pressure to the slide plate 303, so that when the pressure is too high, part of the water flow at the front end of the pressure stabilizing mechanism 3 overcomes the elastic force of the second spring 304 and flows into the interior of the second mounting shell 301, reducing the water pressure inside the equipment. After the pressure decreases, the water flow is squeezed back into the interior of the three-way pipe 1 by the slide plate 303, increasing the water pressure inside the equipment. This balances the water flow pressure at the front end of the pressure control mechanism 2 and ensures the stability of the water flow output by the nozzle mechanism 7.

[0026] Working principle: When using the pressure curved screen cleaning nozzle, the first spring 207 provides a downward pressure to the baffle 203 towards the top of the inlet 202, so that the water flow inside the inlet 202 can only enter the interior of the first mounting shell 201 when the water pressure is greater than the elastic force of the first spring 207, and then flow out through the outlet 208. Then, through the cooperation between the connecting pipe 4 and the nozzle mechanism 7, the water is sprayed to clean the pressure curved screen, thus achieving the purpose of limiting the minimum pressure of the output water flow and preventing the output water pressure from being too low to effectively clean. During this process, through the cooperation between the turntable 204, the screw 205, and the mounting bracket 206, the operator can adjust the tension of the first spring 207 by rotating the turntable 204, thereby changing the output threshold of the pressure control mechanism 2.

[0027] The joystick 209 allows the user to easily rotate the turntable 204. The water pressure sensor 5 detects the water pressure inside the connecting pipe 4, and the flow sensor 6 detects the flow rate inside the connecting pipe 4.

[0028] The second spring 304 provides a downward pressure to the slide plate 303, so that when the pressure is too high, part of the water flow at the front end of the pressure stabilizing mechanism 3 flows into the second mounting shell 301 to overcome the elastic force of the second spring 304, thereby reducing the water pressure inside the equipment. After the pressure decreases, the water flow is squeezed back into the three-way pipe 1 by the slide plate 303, thereby increasing the water pressure inside the equipment. This balances the water flow pressure at the front end of the pressure control mechanism 2 and ensures the stability of the water flow output from the nozzle mechanism 7.

[0029] The sealing ring 305 ensures a tight seal between the slide plate 303 and the second mounting housing 301 to prevent leakage. The main channel 702 serves as the main output channel, and the cooperation between the secondary channel 703 and the one-way valve 704 facilitates the user to inject auxiliary cleaning agent into the main channel 702, thereby improving cleaning efficiency.
