Description

Technical Field

[0001] This application belongs to the field of filter technology, specifically a filter. Background Technology

[0002] A filter is a common barrier device used to filter fluids. In the liquid flow path, filters are usually installed in the upper and lower passages of the valve block to filter the liquid entering and leaving the valve, thereby protecting the valve block.

[0003] Because the valve block and filter are two separate units in the existing technology, they occupy a lot of space during installation, which increases the overall volume of the passage and the overall cost of setting up the passage. In addition, the installation requires two separate installations, which is also inconvenient and further increases the cost. Therefore, it is necessary to design a filter to solve the above problems. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies by designing a filter that combines the valve block and filter assembly, thus solving the problem that "the separate existence of valve blocks and filters in existing technologies leads to increased costs for pathway installation".

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A filter, including

[0007] Valve block one is used to support the overall device. Valve block two is fixedly connected to the upper end of valve block one. A filter assembly is provided on the inner wall of valve block two. A filter sleeve is fixedly connected to the lower surface of valve block one. A backflushing assembly is provided on the inner wall of valve block one. A pressure gauge is installed on the front surface of valve block one.

[0008] Preferably, the filter assembly includes a water inlet pipe that passes through the front end of the second valve block. The inner walls of the second valve block and the first valve block are provided with a drainage groove, and the water inlet pipe is disposed on the inner wall of the drainage groove.

[0009] Preferably, a filter pipe is installed at the left end of the water inlet pipe, and a drainage cavity is provided on the inner wall of the filter sleeve, with the filter pipe inserted into the inner wall of the drainage cavity.

[0010] Preferably, a drain pipe is installed at the upper end of the valve block two, the lower end of the drain pipe is connected to the drain trough, and a sealing cap is threaded onto the upper surface of the valve block one.

[0011] Preferably, the backflushing assembly includes a drain trough, which is disposed at the left end of the valve block one, and the right end of the drain trough is connected to the inner wall of the drainage chamber. A backflushing pipe is installed at the left end of the valve block one.

[0012] Preferably, a sealing block is fixedly connected to the inner wall of the valve block one, and a movable block is slidably connected to the inner wall of the valve block one.

[0013] Preferably, a transmission rod is fixedly connected to the right end of the movable block, and the transmission rod passes through and is slidably connected to the right end of the valve block.

[0014] Preferably, a transmission block is fixedly connected to the right end of the transmission rod, and an adjusting screw is rotatably connected to the right end of the valve block. The transmission block is threadedly connected to the outer wall of the adjusting screw.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] 1. This application adopts a method of setting valve block one, valve block two and filter assembly as an integrated structure, which greatly reduces the size of the overall device, and only requires one installation to achieve connection, making the overall device less expensive to set up and easier to install and disassemble.

[0017] 2. This application uses backwashing to clean the filter tube. When the filter tube becomes clogged, the movable block can be adjusted to cooperate with the sealing block to close the drain tank. Then the backwash pipe can be opened, and pure water can be injected into the backwash pipe. The water flows in the opposite direction through the filter path and carries the impurities out of the inlet pipe. This can clean the filter tube. The whole device is relatively easy to clean.

[0022] Reference Figure 1 - Figure 3 A filter, including

[0023] Valve block 1 supports the entire device. Valve block 2 is fixedly connected to the upper end of valve block 1. A filter assembly 3 is installed on the inner wall of valve block 2. The filter assembly 3 can be used to filter the fluid passing through valve block 1 and valve block 2. A filter sleeve 4 is fixedly connected to the lower surface of valve block 1. The filter sleeve 4 can provide a place to accommodate the filter assembly 3. A backflushing assembly 5 is installed on the inner wall of valve block 1. The backflushing assembly 5 can cooperate with the internal filtration path of the device to achieve reverse cleaning. A pressure gauge 6 is installed on the front surface of valve block 1 to detect the internal pressure of the device. When the internal pressure of the device is detected to be too high, it means that the filter assembly 3 is blocked.

[0024] In this embodiment, when using the filter, the fluid to be filtered first enters the device through the inlet pipe 31 in the filter assembly 3. Since the left end of the inlet pipe 31 is equipped with a filter pipe 34, and the filter pipe 34 is inserted into the drain cavity 36 on the inner wall of the filter sleeve 4, the fluid will pass through the filter pipe 34. During this process, impurities in the fluid are intercepted by the filter pipe 34, thus achieving filtration. The filtered pure fluid enters the drain cavity 36. Since the drain cavity 36 is connected to the drain groove 33 jointly provided on the inner walls of valve block 1 and valve block 2, the pure fluid then flows into the drain groove 33 and is finally discharged from the device through the drain pipe 32 connected to the drain groove 33, completing the normal filtration process.

[0025] During the filtration process, the pressure gauge 6 installed on the front surface of valve block 1 can detect the internal pressure of the device in real time. When the pressure is too high, it indicates that the filter tube 34 is blocked, and the backwash assembly 5 needs to be activated for cleaning. During cleaning, first rotate the adjusting screw 54 in the backwash assembly 5. Since the transmission block 53 is threaded to the outer wall of the adjusting screw 54, and the transmission block 53 is fixedly connected to the transmission rod 55, the rotation of the adjusting screw 54 will drive the transmission block 53 to move to the left, which in turn drives the transmission rod 55 to move to the left synchronously. Since the left end of the transmission rod 55 is fixedly connected to the movable block 56, the movable block 56 slides on the inner wall of valve block 1. The movable block 56 moves to the left with the transmission rod 55 until it is fixed to the inner wall of valve block 1. The sealing block 57 fits in place, sealing the drain trough 33 to prevent pure fluid from flowing into the drain trough 33 during subsequent rinsing, which would cause a drop in water pressure. Then, the external rinsing channel is connected to the backwash pipe 52. The pure rinsing water flows through the backwash pipe 52 into the drain trough 51, and the right end of the drain trough 51 is connected to the drain chamber 36. The rinsing water then enters the drain chamber 36 and flows back through the filter pipe 34, causing the impurities trapped in the filter pipe 34 to flow back into the inlet pipe 31 and finally out of the device from the inlet pipe 31, thus achieving backwashing and cleaning of the filter pipe 34. When the filter pipe 34 needs to be replaced, the sealing cap 35 connected to the thread on the upper surface of the valve block 1 can be unscrewed, and the filter pipe 34 can be directly removed from the device for replacement.

[0026] As a preferred embodiment, the filter assembly 3 includes an inlet pipe 31, which is mainly used to guide the liquid to be filtered into the device. The inlet pipe 31 passes through the front end of the valve block 2. The inner walls of the valve block 2 and the valve block 1 are jointly provided with a drain groove 33, which is mainly used for the filtered fluid to pass through. The inlet pipe 31 is located on the inner wall of the drain groove 33.

[0027] As a preferred method, a filter pipe 34 for filtering fluid is installed at the left end of the inlet pipe 31. The drain pipe 32 can directly guide the fluid into the filter pipe 34. The fluid can pass through the filter pipe 34, while impurities in the fluid will be left inside the filter pipe 34. The inner wall of the filter sleeve 4 is provided with a drain chamber 36 for discharging the filtered fluid. The filter pipe 34 is inserted into the inner wall of the drain chamber 36.

[0028] As a preferred embodiment, a drain pipe 32 is installed at the upper end of valve block 2, and the lower end of the drain pipe 32 is connected to the drain trough 33. During filtration, the fluid enters the device from the inlet pipe 31, then passes through the filter pipe 34, and returns to the inside of the drain trough 33 through the drain chamber 36. Finally, it is discharged from the device through the drain pipe 32. A sealing cover 35 is threaded onto the upper surface of valve block 1. When the filter pipe 34 needs to be replaced, the sealing cover 35 can be removed directly, and then the filter pipe 34 can be taken out from the device.

[0029] As a preferred embodiment, the backwash assembly 5 includes a drain trough 51 for discharging flushing water. The drain trough 51 is located at the left end of the valve block 1, and the right end of the drain trough 51 is connected to the inner wall of the drain chamber 36. When fluid enters the interior of the filter tube 34 from the outside, it will cause the impurities inside the filter tube 34 to flow back into the interior of the drain pipe 32. The left end of the valve block 1 is equipped with a backwash pipe 52, which is used to connect to the external flushing channel.

[0030] As a preferred method, a sealing block 57 is fixedly connected to the inner wall of valve block 1, and a movable block 56 is slidably connected to the inner wall of valve block 1. When the sealing block 57 and the movable block 56 are in contact, the drain trough 33 can be sealed, thus preventing pure fluid from flowing into the interior of the drain trough 33 and causing a drop in water pressure.

[0031] As a preferred embodiment, the right end of the movable block 56 is fixedly connected to a transmission rod 55 for moving the movable block 56. The transmission rod 55 passes through and is slidably connected to the right end of the valve block 1. By pushing the transmission rod 55, the movable block 56 can be moved to the left to close the drainage groove 33.

[0032] As a preferred embodiment, a transmission block 53 is fixedly connected to the right end of the transmission rod 55, and an adjusting screw 54 is rotatably connected to the right end of the valve block 1. The transmission block 53 is threadedly connected to the outer wall of the adjusting screw 54. By rotating the adjusting screw 54, the transmission block 53 can be moved to the left, which in turn can drive the transmission rod 55 and the movable block 56 to move to the left synchronously, thereby closing the drainage trough 33.
