Description

Technical Field

[0001] The utility model relates to the field of liquid filtering equipment, in particular to a filtering equipment for removing impurities from liquid. Background Art

[0002] Liquid impurity removal filtration equipment is used to remove suspended matter, particulate matter and other impurities from liquids. However, fertilizer additives may contain various impurities such as dust, microorganisms, unreacted raw materials, etc. during the production process. These impurities may affect the quality, effect and safety of fertilizer additives. Therefore, it is crucial to use liquid impurity removal filtration equipment to treat fertilizer additives to ensure product quality. For example, bag filters use two layers of bag filter media inside and outside, disc filters flow between multiple discs, paperboard filters filter through porous paperboard, and activated carbon filters use the adsorption properties of activated carbon to remove impurities. As the filtration process progresses, the filter media will gradually become saturated or damaged and need to be replaced regularly. If it is not disassembled, the filter media cannot be replaced, which will lead to a decrease in the filtration effect.

[0003] Before using traditional filtration equipment for liquid impurity removal, it is necessary to ensure that the equipment is clean and intact, and select the appropriate filter medium according to the needs. During the installation process, the filter medium is placed correctly and the inlet and outlet pipes are connected. The drive device and control system are debugged to achieve the ideal filtering effect. During operation, the filtering speed and pressure are adjusted according to the properties of the liquid and the filtering accuracy requirements. At the same time, the filter element is regularly disassembled and installed, the filter medium is replaced, and the equipment is cleaned and maintained to ensure its long-term stable operation and adapt to different production needs. Through these steps, the filtration equipment for liquid impurity removal can effectively remove impurities and improve product quality.

[0004] When disassembling and assembling the filter device, only the entire filter device can be disassembled and assembled, and it is difficult to disassemble and assemble the internal filter element alone, resulting in the inability to quickly clean the internal filter element. During long-term use, a large amount of dirt and sediment will accumulate, which will reduce the filtration efficiency and affect product quality. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 - Figure 3, an embodiment provided by the utility model: a filtering device for removing impurities from liquid, comprising an outer shell 1, a sealing top cover 2 is slidably connected to the top of the outer shell 1, an external threaded sleeve 4 is internally threadedly connected to the sealing top cover 2, a filter element 3 is fixedly connected to the bottom of the external threaded sleeve 4, an outer wall of the filter element 3 is slidably connected to the inner wall of the outer shell 1, a positioning hole 10 is provided inside the outer shell 1, a positioning rod 9 is fixedly connected to the lower surface of the sealing top cover 2, a rotating sleeve 5 is rotatably connected to the outer wall of the sealing top cover 2, a gear ring 6 is fixedly connected to the inner wall of the rotating sleeve 5, a gear 7 is rotatably connected to the inside of the sealing top cover 2, the gear ring 6 is meshed with the gear 7, a screw 8 is internally threadedly connected to the gear 7, and an outer wall of the screw 8 is threadedly connected to the inside of the sealing top cover 2 and the outer shell 1, a lifting assembly is provided on the top of the sealing top cover 2, and the lifting assembly includes a handle 11, and the lower surface of the handle 11 is fixedly connected to the upper surface of the sealing top cover 2;

[0026] Specifically, first, the liquid starts from the external water pipe 15, is transported to the inside of the connecting pipe 12, and then flows into the inside of the filter element 3 for filtration. In this process, the debris and impurities in the liquid are intercepted and retained by the filter element 3, and the clean liquid flows out through the filter element 3. As time goes by, more and more debris will accumulate inside the filter element 3. By driving the rotating sleeve 5 to rotate on the outer wall of the sealing top cover 2, the gear ring 6 will rotate inside the sealing top cover 2. Due to the meshing of the gear ring 6 with multiple gears 7, the gear 7 will rotate with the rotation of the gear ring 6. The gear 7 is connected to the screw 8, so when the gear 7 rotates, it will drive the screw 8 to rotate. The rod 8 moves inside the sealing top cover 2 and the outer shell 1. When the screw rod 8 is completely moved to the inside of the sealing top cover 2, the filter element 3 can be easily pulled out by the handle 11. Then, by rotating the filter element 3, the external threaded sleeve 4 is rotated inside the sealing top cover 2, and the filter element 3 can be easily removed. During installation, the positioning rod 9 at the bottom of the sealing top cover 2 needs to be inserted into the positioning hole 10 inside the outer shell 1 to ensure that the inlet of the filter element 3 is accurately fitted with the connecting pipe 12, thereby achieving the effect of efficient impurity removal, which not only improves the filtration efficiency, but also greatly simplifies the replacement process of the filter element 3, bringing great convenience to the user.

[0027] Reference Figure 1 , Figure 4 and Figure 5The outer shell 1 is fixedly connected with a connecting pipe 12, which fits with the filter element 3. The bottom of the outer shell 1 is fixedly connected with a drain pipe 13, the outer wall of the connecting pipe 12 is fixedly connected with a connecting flange 14, the outer wall of the connecting flange 14 fits with an external water pipe 15, the inner part of the connecting flange 14 is fixedly connected with a positioning sleeve 17, the inner part of the connecting flange 14 is threadedly connected with a threaded rod 16, one end of the threaded rod 16 is rotatably connected with a push block 18, the outer wall of the push block 18 is slidably connected to the inner wall of the positioning sleeve 17, the inner part of the positioning sleeve 17 is slidably connected with a clamping block 19, the clamping block 19 and the positioning sleeve 17 are both slidably connected to the inside of the external water pipe 15, the outer wall of the clamping block 19 is fixedly connected with a telescopic rod 20, the outer wall of the telescopic rod 20 is provided with a spring 21, and both ends of the spring 21 are fixedly connected to the outer wall of the clamping block 19;

[0028] Specifically, first drive the threaded rod 16 to rotate, which will drive the push block 18 to move on the inner wall of the positioning sleeve 17, and the push block 18 will further push the two clamping blocks 19 to move inside the positioning sleeve 17 and the external water pipe 15. In this process, the spring 21 is stretched and stores huge elastic potential energy. When the filter device needs to be disassembled, it is only necessary to rotate the threaded rod 16 in the opposite direction, and at the same time release the elastic potential energy in the spring 21 to make it rebound, driving the clamping block 19 to quickly return to the inside of the positioning sleeve 17. At this time, the fixed relationship between the filter device and the connecting structure is released, and the filter device can be easily removed.

[0029] Working principle: When it is necessary to use the filtering equipment for removing impurities from liquid, first, the external water pipe 15 transports the liquid to the inside of the filter element 3 through the connecting pipe 12 for filtration, and the impurities in the liquid are left inside the filter element 3, and then the rotating sleeve 5 is driven on the outer wall of the sealing top cover 2, thereby driving the gear ring 6 to rotate inside the sealing top cover 2, so that multiple gears 7 rotate with the rotation of the gear ring 6, thereby driving the screw 8 to move inside the sealing top cover 2 and the outer shell 1 through the rotation of the gear 7. When the screw 8 is completely moved to the inside of the sealing top cover 2, the filter element 3 can be pulled out through the handle 11, and then the filter element 3 is rotated to make the external threaded sleeve 4 rotate inside the sealing top cover 2, so as to facilitate the removal of the filter element 3 and then clean the filter element 3. During installation, it is necessary to first insert the positioning rod 9 at the bottom of the sealing top cover 2 into the positioning hole 10 inside the outer shell 1 for positioning, so that the inlet of the filter element 3 can fit with the connecting pipe 12, thereby achieving the effect of efficient impurity removal, and then drive the threaded rod 16 to rotate inside the connecting flange 14, thereby driving the push block 18 to move on the inner wall of the positioning sleeve 17, and then push the two clamping blocks 19 to move inside the positioning sleeve 17 and the external water pipe 15, and at the same time stretch the spring 21 to achieve the installation of the filter device. When disassembling, it is only necessary to rotate the threaded rod 16 in the opposite direction. At this time, the spring 21 is no longer subjected to force and rebounds, driving the clamping block 19 back to the inside of the positioning sleeve 17, and then the filter device can be removed, thereby facilitating the disassembly and assembly of the filter device.
