Description

Technical Field

[0001] The present invention relates to the technical field of pure water filtration, and specifically relates to a detachable down-press type pure water filtration device. Background Art

[0002] Existing pure water filtration devices are widely used in industrial fields, the food and beverage industry, and the automotive field. In the electronics industry, they are used for pre-filtration of reverse osmosis water systems and deionized water systems; in the chemical industry, they are used for filtration of organic solvents, inks, etc.; in the pharmaceutical industry, they are used for filtration of pharmaceuticals, biological, and plasma products, filtration of compressed air and gases, etc.; in the food and beverage industry, they can be used for filtration of beverages, beers, mineral waters, etc. to ensure the taste and quality of products; in the automotive field, automotive filter elements include air filters, oil filters, and air conditioner filters, etc., which respectively undertake important functions such as filtering the air entering the engine, impurities in the oil, and purifying the air inside the vehicle.

[0003] In the prior art, the filter element structure is mostly directly installed inside the filtration device, and most of them are fixedly installed. On the one hand, this installation form is not convenient for disassembly and replacement. Since the filter element itself is a consumable, when the filter element is used for too long, the impurities intercepted and filtered inside will increase significantly, and it is very easy to cause the filter element to be blocked, which will seriously affect the filtration efficiency and quality. Therefore, it is necessary to disassemble and clean or directly replace it according to the usage situation.

[0004] Moreover, even if some technical devices can achieve the replacement and disassembly of the filter element, usually some mechanical structures are designed to achieve disassembly, and complex operations are also required during replacement and disassembly, and the specific implementation is also more troublesome.

[0005] On the other hand, after the water body is put into the device in the prior art, the natural filtration of the water body is mostly achieved by the gravity of the water body. This filtration form has relatively low efficiency and can only rely on the gravity of the water body to achieve filtration. This form is convenient to achieve when the weight of the water body is large, but when the flow rate of the water body becomes small, the efficiency will become very poor, seriously affecting the filtration efficiency and quality.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a detachable down-press type pure water filtration device with a reasonable structure, improved filtration quality and efficiency. Summary of the Invention

[0007] The purpose of the present invention is to provide a detachable down-press type pure water filtration device aiming at the deficiencies of the prior art; the technical solution is as follows:

[0008] A detachable downward pressure pure water filtration device, including a filtration tank. The upper end of the filtration tank is open, and a fixed plate is provided at the middle part of the filtration tank. A plurality of detachable filter elements are installed on the fixed plate. And a downward pressure mechanism is also installed at the bottom of the filtration tank. The main shaft of the downward pressure mechanism passes upward through the fixed plate, and a lower pressing plate is installed at the shaft end. The size of the lower pressing plate is the same as the inner diameter size of the filtration tank. The lower pressing plate can be correspondingly pressed downward on the fixed plate under the action of the downward pressure mechanism, and can be correspondingly extended out of the filtration tank upward.

[0009] And a water inlet pipe is also provided on the left side of the upper end of the filtration tank, and a water outlet pipe is correspondingly provided on the right side of the lower end of the filtration tank. The water body entering from the water inlet pipe is filtered by the filter element after passing through the filter element under the downward pressure of the upper lower pressing plate above, and then discharged from the water outlet pipe.

[0010] Furthermore, pump bodies are installed on both the water inlet pipe and the water outlet pipe.

[0011] Furthermore, the filter element is in a long strip structure. An intermediate area is provided in the middle part of the filter element. The upper end of the intermediate area is open. And a circumferential clamping plate extending laterally outward is provided at the upper end of the filter element. And a stepped hole corresponding to the position of the circumferential clamping plate is provided on the fixed plate. A circumferential clamping groove corresponding to the position of the circumferential clamping plate is provided on the stepped hole. When the filter element is correspondingly placed in the stepped hole, the circumferential clamping plate at the upper end of the filter element is correspondingly embedded in the circumferential clamping groove of the stepped hole.

[0012] And when the water body enters from the water inlet pipe, the water body enters the intermediate area in the middle part of the filter element, and the filter element is fixed by the gravity of the water body.

[0013] Furthermore, the stepped holes are evenly distributed on the fixed plate. When the water filtration is completed, the filter element can be directly taken out from the stepped holes.

[0014] Furthermore, a lifting mechanism is also installed at the bottom of the filtration tank. The main shaft of the lifting mechanism extends upward into the filtration tank and a lifting mesh plate is installed at the shaft end. The lifting mesh plate can correspondingly support the bottom of the filter element upward, jacking up the filter element, so that the filter element is separated from the stepped hole.

[0015] Furthermore, a through hole corresponding to the position of the main shaft of the downward pressure mechanism is also provided on the lifting mesh plate, and the main shaft of the downward pressure device correspondingly passes through the through hole.

[0016] Furthermore, a sealing ring is also installed between the main shaft of the downward pressure mechanism and the fixed plate, and a sealing ring is also provided on the outer circumference of the lower pressing plate. Three lifting mechanisms are provided at the bottom of the filtration tank in total.

[0017] Beneficial effects: The present invention has the following beneficial effects:

[0018] 1) In the present invention, a separable and detachable filter element is provided. On the one hand, it can realize the water filtration function of the overall structure. On the other hand, it can realize the disassembly and replacement of the filter element, and the structural design is very reasonable.

[0019] 2) In the present invention, a pressing mechanism and a lower pressing plate are correspondingly provided. Through the cooperation of the pressing mechanism and the lower pressing plate, the rapid filtration of water is realized, effectively improving the filtration efficiency and quality, and the overall structural design is relatively ingenious.

[0020] 3) In the present invention, the filter element is detachable and replaceable. The upper end of the filter element is provided with a circumferential clamping plate, and a hollow area is arranged inside. And the fixing plate is provided with a step hole corresponding to the position of the circumferential clamping plate, and the detachable installation is realized through the cooperation of the two.

[0021] 4) During the specific filtration in the present invention, after the filter tank is filled with water, the water above will press on the circumferential clamping plate, and the water directly enters the middle area of the filter element. Therefore, the filter element is pressed by the gravity of water as a whole, and the filter element is fixed as a whole during filtration, and the structure is stable.

[0022] 5) In the present invention, a lifting mechanism and a lifting net plate are also provided. When the lifting mechanism drives the lifting net plate to move upward, all the filter elements can be driven to move upward, so that the filter elements can be more conveniently lifted upward, and it is more convenient to cooperate with the staff to replace the filter elements correspondingly. The structural design is very ingenious and reasonable. Description of the Drawings

Detailed implementation mode

[0030] The present invention will be further clarified below in conjunction with the accompanying drawings and specific embodiments. These embodiments are implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0031] As Figure 1 shown, a detachable downward pressure pure water filtration device includes a filtration tank 1. The upper end of the filtration tank 1 is open, and a fixing plate 2 is provided at the middle part of the filtration tank 1. A plurality of detachable filter cores 3 are installed on the fixing plate 2; and a downward pressure mechanism 4 is also installed at the bottom of the filtration tank 1. The main shaft of the downward pressure mechanism 4 passes upward through the fixing plate 2, and a lower pressing plate 5 is installed at the shaft end. The size of the lower pressing plate 5 is the same as the inner diameter size of the filtration tank 1. The lower pressing plate 5 can be correspondingly pressed against the fixing plate 2 downward under the action of the downward pressure mechanism 4 and can correspondingly extend out of the filtration tank 1 upward.

[0032] As Figure 2 shown, a water inlet pipe 6 is also provided on the left side of the upper end of the filtration tank 1, and a water outlet pipe 7 is correspondingly provided on the right side of the lower end of the filtration tank 1; the water body entering from the water inlet pipe 6 passes through the filter core 3 under the downward pressure of the upper lower pressing plate 5 above and is filtered by the filter core 3 and then discharged from the water outlet pipe 7.

[0033] Pump bodies are installed on both the water inlet pipe 6 and the water outlet pipe 7.

[0034] As Figure 3 shown, the filter core 3 is in a long strip structure. An intermediate area 8 is provided in the middle part of the filter core 3. The upper end of the intermediate area 8 is open, and a circumferential clamping plate 9 extending laterally outward is provided at the upper end of the filter core 3. And a stepped hole 10 corresponding to the position of the circumferential clamping plate 9 is provided on the fixing plate 2, and a circumferential clamping groove 11 corresponding to the position of the circumferential clamping plate 9 is provided on the stepped hole 10. When the filter core 3 is correspondingly placed in the stepped hole 10, the circumferential clamping plate 9 at the upper end of the filter core 3 is correspondingly embedded in the circumferential clamping groove 11 of the stepped hole 10;

[0035] And when the water body enters from the water inlet pipe 6, the water body enters the intermediate area 8 in the middle part of the filter core 3, and the filter core 3 is fixed by the gravity of the water body.

[0036] As Figure 6 shown, the stepped holes 10 are evenly distributed on the fixing plate 2. When the water filtration is completed, the filter core 3 can be directly taken out from the stepped holes 10.

[0037] As Figure 4 and Figure 5As shown, a lifting mechanism 12 is also installed at the bottom of the filter box 1. The main axis of the lifting mechanism 12 extends upward into the filter box 1 and a lifting mesh plate 13 is installed at the end of the axis. The lifting mesh plate 13 can support the bottom of the filter element 3 upward and lift the filter element 3 upward, thereby separating the filter element 3 from the step hole 10.

[0038] The lifting mesh plate 13 is further provided with a through hole 14 corresponding to the position of the main shaft of the pressing mechanism 4 , and the main shaft of the pressing mechanism passes through the through hole 14 accordingly.

[0039] A sealing ring is installed between the main shaft of the pressing mechanism 4 and the fixed plate 2 , and a sealing ring is also provided on the outer circle of the pressing plate 5 ; there are three lifting mechanisms 12 at the bottom of the filter box 1 .

[0040] The specific working process of the present invention is as follows: the filter element in this device is placed in the stepped hole of the fixed plate, and is installed through the cooperation of the annular clamping plate and the annular clamping groove. The filter element itself is a long strip structure and can extend downward to the bottom of the fixed plate. Before the water inlet pipe enters the water, the lower pressure plate is first lifted upward to the upper position of the water inlet pipe of the filter box through the downward pressure mechanism so as not to hinder the water inlet of the water inlet pipe. After that, the water inlet pipe injects water into the filter box, and the injected water enters the middle area of the middle part of the filter element accordingly. After being filtered by the filter element, the water flows downward and is then discharged through the outlet pipe. In the above process, if filtration is only carried out by relying on the gravity of the water body, the filtration efficiency is very low. Therefore, the technical solution of the present invention is correspondingly provided with a downward pressure mechanism and a downward pressure plate.

[0041] When the filter box is filled with water, the downward pressure mechanism can be used to drive the downward pressure plate to gradually pressurize the water below from top to bottom, thereby speeding up the process of water passing through the filter element. The water can flow downward through the filter element more quickly. The specific downward pressure speed of the lower pressure plate is set according to actual conditions. The downward pressure speed should be moderate and will not cause damage to the filter element. It can also speed up the filtration of the water and effectively improve the filtration efficiency of the water. The structural setting is also relatively clever and reasonable.

[0042] The filter element of the present invention is removable and replaceable. First of all, the filter element in the present invention is not fixedly installed, but directly detachably installed. An annular clamping plate is provided on the upper end of the filter element, and a hollow area is provided inside. A step hole corresponding to the position of the annular clamping plate is provided on the fixed plate, and an annular clamping groove is provided on the step hole. Therefore, the installation of the filter element itself is that the annular clamping plate is directly placed in the annular clamping groove. The filter element is long and directly hung downward. During actual filtering, after the filter box is filled with water, the water body above will be pressed on the annular clamping plate, and the water body will directly enter the middle area of the filter element. Therefore, the filter element is pressed down by the gravity of the water as a whole. The filter element is fixed as a whole during filtering, and the structure is stable.

[0043] And when the lower pressing plate presses downward, the filter element is also fixed by the pressure of the lower pressing plate. Therefore, after the filtration is completed, the filter element of the present invention can be directly taken out of the stepped hole as a whole through the separated structure setting for cleaning or replacement, and the structure setting is reasonable.

[0044] In order to cooperate with the disassembly, replacement and cleaning of the filter element in the present invention, a lifting mechanism is also provided at the bottom, and a lifting mesh plate is installed on the main shaft of the lifting mechanism. On the one hand, the lifting mesh plate is a mesh structure, and on the other hand, the range of the mesh plate covers all the filter elements above. When the lifting mechanism drives the lifting mesh plate to move upward, all the filter elements can be driven to move upward, so that the filter elements can be more conveniently lifted upward, and it is more convenient to cooperate with the staff to replace the filter elements accordingly. The structure setting is very ingenious and reasonable.

[0045] And the lifting mesh plate itself is a mesh structure. During the specific filtration process, when the water flows down from above, it will not affect the flow of the water at all. The water can directly flow through the lifting mesh plate, and the overall structure is very reasonable.

[0046] The above specific implementation manners are only a preferred embodiment of the present invention, and are not used to limit the implementation and the scope of the claims of the present invention. Any equivalent changes and modifications made in accordance with the scope of the patent application protection of the present invention should be included within the scope of the patent application of the present invention.
