Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a single-core cylindrical filter. Background Technology

[0002] Single-core cylindrical filters are a common type of industrial filtration equipment, widely used in solid-liquid separation and particle filtration of liquids or gases.

[0003] A single-core cylindrical filter typically consists of a base, a cylinder, and a filter element. The filter element is mounted on the base, and the cylinder covers the filter element. After a period of filtration, the surface of the filter element will absorb a large amount of contaminants, leading to clogging. At this point, the filter element needs to be cleaned or replaced.

[0004] Especially in some high-pressure fluid systems, when the filter element becomes clogged and is not dealt with in time, the internal pressure of the cylinder will rise rapidly. When the internal pressure of the cylinder is too high, it can easily cause the filter element or even the cylinder to explode. This will not only cause a lot of economic losses, but also pose a great safety hazard.

[0005] To address the above problems, this utility model provides a single-core cylindrical filter. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a single-core cylindrical filter.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A single-core cylindrical filter includes a base, a cylinder, and a filter element. The base is fixedly connected to an inlet pipe and an outlet pipe. An adjusting pipe is fixedly connected to the upper end of the cylinder. A pressure relief pipe is provided on the side wall of the adjusting pipe. A protective assembly is installed inside the adjusting pipe. The protective assembly includes a piston, a pressure spring, and a fixed seat. The piston and the adjusting pipe are in a sealed sliding fit. The fixed seat is fixedly installed at the upper end of the adjusting pipe. The pressure spring is disposed between the piston and the fixed seat, with its two ends connected to the piston and the fixed seat respectively. When the system pressure exceeds a set value, the piston compresses the pressure spring and moves upward. When the piston is higher than the pressure relief pipe, the pressure relief pipe can promptly discharge some fluid, quickly reducing the pressure and preventing damage to the filter and related components due to overpressure. This ensures operator safety and normal equipment operation, reduces operator workload and error risk, and improves equipment automation and operating efficiency.

[0009] As a further improvement of this utility model, a sleeve rod is fixedly connected to the bottom of the fixed seat; a guide rod is fixedly connected to the upper end of the piston, and the guide rod is movably connected inside the sleeve rod. The guide rod can move flexibly inside the sleeve rod, which not only ensures the smooth movement of the piston, but also limits the piston.

[0010] As a further improvement of this utility model, a downwardly extending connecting sleeve is formed on the edge of the fixed seat, and an internal thread is formed on the inner wall of the connecting sleeve. The connecting sleeve is sleeved on the outside of the adjusting pipe and engages with the threaded engagement of the adjusting pipe. Through the threaded engagement between the fixed seat and the adjusting pipe, the height position of the fixed seat can be easily adjusted, thereby achieving the adjustment of different pressure levels and meeting different working requirements.

[0011] As a further improvement of this utility model, a threaded hole is provided on one side of the upper surface of the base. A threaded pipe that matches the threaded hole is fixedly connected to the lower end of the filter element, and the upper end of the water outlet pipe is connected to the threaded hole. The filter element is fixedly installed on the base by a threaded connection, which ensures a reliable seal and makes the connection more secure and reliable, thereby avoiding filter element displacement and leakage caused by the impact of high-pressure fluid passing through.

[0012] As a further improvement of this utility model, an inlet valve is connected to the inlet pipe and an outlet valve is connected to the outlet pipe. Both the inlet valve and the outlet valve are regulating valves, which can control the flow rate and on / off of the incoming water, making it convenient for operators to adjust the amount of liquid entering the filter according to actual needs.

[0013] As a further improvement of this utility model, a lower flange is fixedly connected to the upper end of the base, and an upper flange is fixedly connected to the lower end of the cylinder. Several threaded holes are opened on the upper surface of the lower flange, and several through holes are opened on the upper surface of the upper flange. Fixing bolts that are compatible with the threaded holes are inserted into the interior of each of the through holes. A handle is fixedly connected to the upper end of the fixing bolt. The handle is designed to facilitate the operator to tighten the fixing bolt, making the installation and disassembly of the cylinder and the base more convenient.

[0014] As a further improvement of this utility model, a sealing groove is provided on the upper surface of the upper flange, and a sealing gasket adapted to the sealing groove is fixedly connected to the lower surface of the lower flange. The sealing gasket can effectively fill the gap between the upper flange and the lower flange, prevent liquid leakage, and ensure the sealing performance of the filter.

[0015] As a further improvement of this utility model, a sealing ring is fixedly connected to the lower end of the filter element surface. The sealing ring can further enhance the sealing between the filter element and the base, prevent unfiltered liquid from flowing directly out around the filter element, and ensure the filtration effect.

[0016] As a further improvement of this utility model, a pressure gauge is fixedly connected to one side of the upper surface of the cylinder. The pressure gauge can display the pressure inside the filter in real time, so that the operator can understand the working status of the filter in a timely manner and take corresponding measures when the pressure is abnormal.

[0017] As a further improvement of this utility model, several support seats are fixedly connected to the lower surface of the base. The support seats can stably support the filter on the ground, prevent the filter from shaking or tilting during use, and ensure the normal operation of the filter.

[0018] The beneficial effects of this utility model are:

[0019] By incorporating protective components, the piston and pressure spring work together to ensure the filter operates under stable pressure during use. The guide rod and sleeve provide precise guidance for the piston's movement, effectively preventing it from deviating. When the system pressure exceeds the set value, the pressure relief pipe can promptly discharge some fluid, quickly reducing the pressure and preventing damage to the filter and related components due to overpressure. This ensures operator safety and normal equipment operation, reduces operator workload and error risk, and improves the automation level and operating efficiency of the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-3A single-core cylindrical filter includes a base 1, a cylinder 2, and a filter element 3. The base 1 is fixedly connected to an inlet pipe 6 and an outlet pipe 7. An adjusting pipe 8 is fixedly connected to the upper end of the cylinder 2. A pressure relief pipe 23 is provided on the side wall of the adjusting pipe 8. A protective component is provided inside the adjusting pipe 8. The protective component includes a piston 9, a pressure spring 10, and a fixed seat 11. The piston 9 and the adjusting pipe 8 are in a sealed sliding fit. The fixed seat 11 is fixedly installed at the upper end of the adjusting pipe 8. The pressure spring 10 is located between the piston 9 and the fixed seat 11, and its two ends are respectively connected to the piston 9 and the fixed seat 11.

[0026] In this embodiment, a sleeve rod 24 is fixedly connected to the bottom of the fixed base 11; a guide rod 25 is fixedly connected to the upper end of the piston 9. The guide rod 25 is movably connected inside the sleeve rod 24. The sleeve rod 24 provides a precise guide track for the movement of the guide rod 25, ensuring that the guide rod 25 can move along a predetermined direction, thus ensuring the smoothness and accuracy of the piston 9's movement. Of course, the sleeve rod can also be omitted, and the guide rod 25 can be directly installed through the fixed base.

[0027] The fixed seat 11 has a downwardly extending connecting sleeve 26 formed on its edge. The inner wall of the connecting sleeve 26 has an internal thread. The connecting sleeve 26 is fitted over the adjusting pipe 8 and threadedly engages with the adjusting pipe 8. This threaded engagement facilitates the installation and disassembly of the fixed seat 11 and the adjusting pipe 8, thereby simplifying the maintenance of the protective components. It also provides a stable connection after installation and allows for easy adjustment of the position of the fixed seat 11 according to actual needs, enabling the adjustment of different pressure levels to meet various working requirements. For example, the piston and the fixed seat can be connected as a single unit using a pressure spring. By adjusting the height of the fixed seat 11, the pressure spring / piston can be moved synchronously, thereby changing the distance between the piston and the pressure relief pipe, and thus changing the pressure required for pressure relief. Alternatively, a limiting step can be formed at the lower end of the adjusting pipe to accommodate the piston. By adjusting the height of the fixed seat 11, the initial compression of the pressure spring can be changed, thereby changing the initial elastic force of the pressure spring and thus changing the pressure required for pressure relief.

[0028] A mounting threaded hole 4 is provided on one side of the upper surface of the base 1. The lower end of the filter element 3 is fixedly connected to a threaded tube 5 that matches the mounting threaded hole 4. The upper end of the water outlet pipe 7 is connected to the mounting threaded hole 4. A water inlet valve 12 is connected to the water inlet pipe 6. The water inlet valve 12 can effectively control the water inlet flow. A water outlet valve 13 is connected to the water outlet pipe 7. The water outlet valve 13 can quickly adjust the water outlet flow according to actual needs to ensure the normal operation of the filtration system.

[0029] A lower flange 14 is fixedly connected to the upper end of the base 1, and an upper flange 15 is fixedly connected to the lower end of the cylinder 2. Several threaded holes are opened on the upper surface of the lower flange 14, and several through holes are opened on the upper surface of the upper flange 15. Fixing bolts 16 that are compatible with the threaded holes are inserted into the through holes. The thread specifications of the fixing bolts 16 are consistent with the threaded holes, so they can be screwed in and firmly fixed to ensure a reliable connection between the cylinder 2 and the base 1. A handle 17 is fixedly connected to the upper end of the fixing bolt 16. The shape of the handle 17 is convenient for the operator to grip and exert force, making it easy to install and remove the fixing bolts 16.

[0030] A sealing groove 18 is provided on the upper surface of the upper flange 15, and a sealing gasket 19 that matches the sealing groove 18 is fixedly connected to the lower surface of the lower flange 14. The sealing gasket 19 is made of rubber material, which has good elasticity and sealing performance, and can effectively prevent water from leaking from the flange connection. A sealing ring 20 is fixedly connected to the lower end of the surface of the filter element 3. The sealing ring 20 fits tightly with the filter element 3 and can form a seal with the relevant parts of the base 1 after installation, ensuring that the water must be filtered by the filter element 3 before it can flow out, thus ensuring the filtration effect. A pressure gauge 21 is fixedly connected to one side of the upper surface of the cylinder 2, and several support seats 22 are fixedly connected to the lower surface of the base 1. The pressure gauge 21 can display the pressure inside the cylinder 2 in real time and accurately.

[0031] During installation, the threaded tube 5 at the lower end of the filter element 3 is first screwed into the installation threaded hole 4 on one side of the upper surface of the base 1 to complete the installation of the filter element 3. Then, the fixing bolts 16 on the upper surface of the upper flange 15 are used to cooperate with the fixing threaded holes on the upper surface of the lower flange 14 to fix the upper flange 15 at the lower end of the cylinder 2 to the lower flange 14 at the upper end of the base 1. During this process, the sealing gasket 19 on the lower surface of the lower flange 14 is embedded in the sealing groove 18 on the upper surface of the upper flange 15, and the sealing ring 20 at the lower end of the surface of the filter element 3 also plays a sealing role to ensure the sealing of the connection. During filtration, water flows into the cylinder 2 through the inlet pipe 6. The inlet valve 12 at the middle of the inlet pipe 6 can control the water flow rate. After the water is filtered by the filter element 3, it flows out from the outlet pipe 7 on one side of the lower surface of the base 1. The outlet valve 13 at the middle of the outlet pipe 7 can control the water flow rate. The upper end of the outlet pipe 7 is connected to the installation threaded hole 4 to ensure that the water flows out after being filtered by the filter element 3.

[0032] During filter operation, a pressure gauge 21 fixedly connected to one side of the upper surface of the cylinder 2 monitors the pressure inside the cylinder 2 in real time. As the system pressure gradually increases, the piston 9 moves upward under the pressure. During the upward movement of the piston 9, the pressure spring 10 fixedly connected to one end is squeezed, and the pressure spring 10 undergoes elastic deformation, generating a spring force opposite to the direction of pressure. At the same time, during the movement of the piston 9, the guide rod 25 moves within the sleeve 24, guiding the movement of the piston 9 and ensuring the smoothness and accuracy of the piston 9's movement. When the system pressure exceeds the set value, the position of the piston 9 will be higher than the pressure relief pipe, allowing some fluid to be discharged through the pressure relief pipe 23, thereby reducing the pressure inside the system and preventing damage to the filter and related components due to excessive pressure. When the system pressure gradually decreases, the spring force of the pressure spring 10 will push the piston 9 downward, allowing the piston 9 to return to its initial position.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
