Description

Technical Field

[0001] The utility model relates to the technical field of vertical dirt removers, in particular to a vertical dirt remover which is convenient for replacing a screen. Background Art

[0002] In the operation of the heating pipe system, a vertical decontaminator is usually used. The liquid in the heating pipe is transmitted to the vertical decontaminator and filtered by the vertical decontaminator, so that the discharged liquid is relatively clean. This can avoid the phenomenon of clogging of the heating pipe after long-term use. The filter screen used for filtering in the vertical decontaminator needs to be replaced regularly to ensure the smoothness of its infusion. For example, a vertical expansion decontaminator with regular decontamination is disclosed with the publication number CN214344889U. When the motor is working, the threaded rod and the cleaning rod are lowered at the same time. The cleaning rod drives the cleaning wire on the surface of the cleaning ring to grind and clean the inner wall of the filter screen. Then, the threaded rod drives the isolation block to descend while grinding. This method improves the cleaning method of the filter screen, avoids the frequent replacement of the filter screen, and also ensures that the filtering effect of the filter screen is better, reduces the blockage caused by the filter screen not being cleaned for a long time, and improves the convenience of the frequency of cleaning the filter screen surface. However, the vertical expansion decontaminator with regular decontamination still has the following disadvantages in actual use:

[0003] The filter screen inside the traditional vertical dirt remover is mostly inconvenient to disassemble for cleaning or replacement. Usually, a structure for cleaning the filter screen is set inside the dirt remover. However, after a long period of cleaning, dirt still remains around the filter screen, still affecting the smoothness of liquid flow. In view of the above problems, it is urgently necessary to carry out innovative design based on the original vertical dirt remover. Utility Model Content

[0004] The purpose of the utility model is to provide a vertical dirt collector with an easy-to-replace screen, so as to solve the problem that the filter screen inside the traditional vertical dirt collector mentioned in the above background technology is mostly inconvenient to disassemble for cleaning or replacement, and a structure for cleaning the filter screen is usually provided inside the dirt collector, but after a long period of cleaning, dirt still remains around the filter screen, still affecting the smoothness of liquid circulation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vertical dirt remover that is convenient for replacing a screen, provided with a shell, a liquid inlet is provided at the upper left end of the shell, and a liquid outlet is provided at the lower right end of the shell, a sealing cover is covered on the top of the shell, and a fixing cylinder is fixed to the lower end surface of the sealing cover, a support rod is passed through the lower end of the fixing cylinder, and a connecting rod is fixed to the bottom of the support rod, a connecting cylinder is sleeved on the outer side of the connecting rod, and the connecting cylinder is fixed to the inner bottom surface of the shell;

[0010] Preferably, a fixing plate is fixed to the upper end of the movable cylinder, and the fixing plates are distributed at equal angles, and the height of the fixing plate is consistent with that of the liquid inlet. When the liquid enters the shell through the liquid inlet, it can impact the fixing plate and drive it to rotate.

[0011] Preferably, a limit plate is sleeved on the outer side of the fixed plate, and the cross-section of the limit plate is an arc-shaped structure, and the limit plate is slidably arranged on the inner wall of the shell through a rod body. The limit plate converges the liquid and can drive the movable cylinder to rotate synchronously through the fixed plate.

[0012] Preferably, a guide rod is fixed to the side of the movable cylinder, and the end of the guide rod away from the movable cylinder is made of rubber, and a connecting plate is fixed at the angle between the first filter screen and the second filter screen. When the movable cylinder rotates, the guide rod can be driven to rotate synchronously and contact the connecting plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the vertical dirt remover that is easy to replace the screen is convenient for disassembling, cleaning or replacing the filter, avoiding the phenomenon that a large amount of dirt remains around the filter after long-term use, affecting the smoothness of liquid circulation, and after the filter is disassembled, it is also convenient to simultaneously take out the impurities inside the dirt remover. The specific contents are as follows:

[0014] 1. Connect the support rod to the fixed cylinder through threads. After the sealing cover is closed on the top of the shell, the connecting rod at the lower end can be driven to be stuck in the connecting cylinder, thereby ensuring the stability of the filter after it is installed inside the shell. When the filter needs to be removed for cleaning or replacement, the sealing cover can be opened to simultaneously pull the support rod, the movable cylinder and the filter out of the shell. At the same time, the limit plate can also be slid and removed from the inside of the shell, which will not affect the removal of the filter;

[0015] 2. When the liquid flows into the shell from the liquid inlet, it can impact the fixed plate and then drive the movable cylinder to rotate. When the movable cylinder rotates, it can drive the guide rod to rotate synchronously, and then contact and knock the connecting plate, so that the vibration force can be transmitted to the first filter and the second filter respectively. Through the vibration of the filter, the intercepted impurities can slide to its edge, which will not affect the circulation of the liquid. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, this embodiment adopts the following technical solutions, such as Figure 2 and Figure 5-Figure 6As shown, a movable cylinder 9 is sleeved at the break in the middle of the support rod 6, and the movable cylinder 9 and the support rod 6 are rotatably connected, and the movable cylinder 9 rotates and passes through the first filter screen 12 and the second filter screen 14; a fixed plate 10 is fixed to the upper end of the movable cylinder 9, and the fixed plates 10 are distributed at equal angles, and the height of the fixed plate 10 is consistent with that of the liquid inlet 2; a limiting plate 11 is sleeved on the outer side of the fixed plate 10, and the cross-section of the limiting plate 11 is an arc-shaped structure, and the limiting plate 11 is slidably arranged on the inner wall of the outer shell 1 through the rod body; a guide rod 15 is fixed to the side of the movable cylinder 9, and the end of the guide rod 15 away from the movable cylinder 9 is made of rubber, and the first filter screen A connecting plate 16 is fixed at the angle between the first filter screen 12 and the second filter screen 14; when the liquid flows into the shell 1 from the liquid inlet 2, it can impact the fixed plate 10. The liquid is gathered by the limit plate 11, which can ensure that the liquid impacts the fixed plate 10, and then drives the fixed plate 10 and the movable cylinder 9 to rotate. When the movable cylinder 9 rotates, it can drive the guide rod 15 to rotate synchronously. When the guide rod 15 rotates, it can contact and knock the connecting plate 16, so that the vibration force can be transmitted to the first filter screen 12 and the second filter screen 14 respectively. Through the vibration of the filter screen, the intercepted impurities can slide to its edge, which will not affect the circulation of the liquid.
