Description

Technical Field

[0001] The utility model relates to the technical field of underground filtering equipment, in particular to a full-automatic underground precision filter device. Background Art

[0002] In underground mining operations, such as coal mining and metal mining, a large amount of liquid containing sediment, minerals, suspended matter and other impurities is produced;

[0003] If these impurities are directly discharged or reused without effective filtration, they may cause underground pipeline blockage, increased equipment wear, reduced mining efficiency, and even affect underground production safety. For example, when mine water is discharged, if the impurity content in the water is too high, it will pollute the surface water environment; when fracturing return fluid is reused, impurities may block the fracturing cracks and affect the fracturing effect;

[0004] Traditional downhole filters have low filtering accuracy and a split structure between filter cartridges. During disassembly and maintenance, they are easily stuck between the shell and the filter cartridge due to impurities, causing technical problems such as inconvenience in disassembly.

[0005] Therefore, the utility model proposes a fully automatic downhole precision filter device. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a fully automatic downhole precision filter device.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solution: a fully automatic downhole precision filter device, comprising:

[0008] A filter assembly, the filter assembly is composed of a lower cylinder and an upper shell, the upper shell is arranged at the top opening of the lower cylinder, the top of the upper shell is fixedly connected with a water inlet pipe, the bottom side of the lower cylinder is fixedly connected with a water outlet pipe, and the inner wall of the lower cylinder is provided with an annular limit frame;

[0009] The filter assembly is composed of a filter element, a mounting frame and a connecting frame arranged inside the lower cylinder. The mounting frame is clamped on the annular limiting frame, a placement hole is opened on the mounting frame, and a filter cartridge penetrating the placement hole is arranged on the connecting frame.

[0010] Furthermore, the filter element is provided with an insertion hole, and the diameter of the insertion hole is matched with the diameter of the filter cartridge.

[0011] The beneficial effect of adopting the above further scheme is: under the action of the jack, the filter cartridge is limited to avoid deformation and tilting of the filter cartridge under the impact of water flow during use, and the gap between the handle and the filter element is reduced, thereby improving the filtering effect.

[0012] Furthermore, a handle is provided on the connecting frame, and two handles are provided in total, and the two handles are symmetrical to each other at the center of the connecting frame.

[0013] The beneficial effect of adopting the above further scheme is that when the filter assembly is disassembled, the connecting frame can be directly pulled out from the filter assembly through the handle, avoiding the technical problem of impurities getting stuck and making it difficult to pull the filter assembly out of the lower cylinder.

[0014] Furthermore, the mounting frame is provided with springs, the springs are distributed in a ring shape, and the angles between two adjacent springs are equal.

[0015] The beneficial effect of adopting the above further scheme is: under the action of the spring, when the upper shell is threadedly connected to the top of the lower cylinder, it will drive the spring to squeeze and contract, so that the spring drives the mounting frame to squeeze downward to limit the position, thereby avoiding the mounting frame from moving up and down in the lower cylinder during use.

[0016] Furthermore, a mounting plate is provided at the bottom of the lower cylinder, and a mounting hole is provided on the mounting plate.

[0017] The beneficial effect of adopting the above further solution is that the lower cylinder is fixed at a specified position by bolts under the action of the mounting plate, thereby preventing the lower cylinder from tilting or shifting during use.

[0018] Furthermore, a first connection disk is disposed at one end of the lower cylinder close to the upper shell, and a second connection disk is disposed at one end of the upper shell close to the lower cylinder, and the first connection disk and the second connection disk are in contact with each other.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that a first connecting plate and a second connecting plate are arranged on the lower cylinder and the upper shell, so that the lower cylinder and the upper shell are not only connected by threads, but also have a flange connection, thereby avoiding the technical problem of excessive water pressure in the filter assembly causing separation between the lower cylinder and the upper shell.

[0020] Furthermore, a threaded sleeve is provided on the inner wall of one end of the upper shell body located at the lower cylinder body, the threaded sleeve is threadedly connected to the inner wall of the lower cylinder body, and the bottom of the threaded sleeve is in contact with the top of the spring.

[0021] The beneficial effect of adopting the above further scheme is: under the action of the threaded sleeve, the upper shell can be threadedly connected to the lower cylinder through the threaded sleeve for simple limiting fixation, and the top of the spring is further squeezed by the threaded sleeve, so that the spring squeezes and limits the mounting frame, thereby avoiding displacement of the mounting frame during use.

[0022] Compared with the prior art, the advantages and positive effects of the utility model are:

[0023] 1. In the utility model, by setting the filter assembly, the device can perform graded filtration during use. When the liquid enters the upper shell through the water inlet pipe, it first contacts the filter cartridge. Under the action of the filter cartridge, the liquid is filtered for the first time, and the larger impurities in the water are collected in the filter cartridge. The filtered liquid passes through the filter cartridge and enters the filter element, and is further filtered by the filter element, so that the smaller impurities in the water are adsorbed by the filter element, thereby improving the filtering effect of the device.

[0024] 2. In the utility model, since the filter cartridge is responsible for filtering larger impurities, it is necessary to clean and maintain the filter cartridge regularly during use to avoid the filter cartridge being blocked during use, resulting in inability to filter. During maintenance, after separating the upper shell body from the lower cylinder body, the connecting frame and the mounting frame are separated by pulling the handle, and multiple filter cartridges can be pulled out from the socket at the same time, thereby improving the work efficiency when replacing the filter cartridge.

[0032] 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.

[0033] like Figure 1-4 As shown, the utility model provides a technical solution: a fully automatic downhole precision filter device, comprising:

[0034] The filter assembly 1 is composed of a lower cylinder 11 and an upper shell 12. The upper shell 12 is arranged at the top opening of the lower cylinder 11. The top of the upper shell 12 is fixedly connected with a water inlet pipe 121, and the bottom side of the lower cylinder 11 is fixedly connected with a water outlet pipe 111. The inner wall of the lower cylinder 11 is provided with an annular limit frame 113.

[0035] The filter assembly 2 is composed of a filter element 21, a mounting frame 22 and a connecting frame 23 arranged inside the lower cylinder 11. The mounting frame 22 is clamped on the annular limiting frame 113. A placement hole 221 is provided on the mounting frame 22. A filter cartridge 232 penetrating the placement hole 221 is provided on the connecting frame 23. A plug hole 211 is provided on the filter element 21. The diameter of the plug hole 211 matches the diameter of the filter cartridge 232. A mounting plate 112 is provided at the bottom of the lower cylinder 11. A mounting hole is provided on the mounting plate 112. A first connecting plate 114 is provided at one end of the lower cylinder 11 close to the upper shell 12. A second connecting plate 122 is provided at one end of the upper shell 12 close to the lower cylinder 11. The first connecting plate 114 and the second connecting plate 122 are in contact with each other. A threaded sleeve 123 is provided on the inner wall of one end of the upper shell 12 located at the lower cylinder 11. The threaded sleeve 123 is threadedly connected to the inner wall of the lower cylinder 11, and the bottom of the threaded sleeve 123 contacts the top of the spring 222. Through the setting of the filter component 2, the device can perform graded filtration during use. When the liquid enters the interior of the upper shell 12 through the water inlet pipe 121, it first contacts the filter cartridge 232. Under the action of the filter cartridge 232, the liquid is filtered for the first time, and larger impurities in the water are collected in the filter cartridge 232. The filtered liquid passes through the filter cartridge 232 and enters the filter element 21, and is further filtered by the filter element 21, so that smaller impurities in the water are adsorbed by the filter element 21, thereby improving the filtering effect of the device.

[0036] Furthermore, Figure 2 - Figure 4As shown: a handle 231 is provided on the connecting frame 23, and there are two handles 231 in total, and the two handles 231 are symmetrical to each other at the center of the connecting frame 23. Since the filter cartridge 232 is responsible for filtering larger impurities, the filter cartridge 232 needs to be cleaned and maintained regularly during use to avoid the filter cartridge 232 being blocked during use, resulting in the inability to filter. During maintenance, after the upper shell body 12 and the lower cylinder body 11 are separated, the connecting frame 23 and the mounting frame 22 are separated by pulling the handle 231, so that multiple filter cartridges 232 can be pulled out from the jack 211 at the same time, thereby improving the work efficiency when replacing the filter cartridge 232.

[0037] The above solution also has the problem that the mounting frame 22 may be displaced during use. Figure 4 As shown: In the present embodiment, springs 222 are arranged on the mounting frame 22, and the springs 222 are distributed in a ring shape, and the angles between two adjacent springs 222 are equal. Under the action of the springs 222, when the upper shell 12 is threadedly connected to the top of the lower cylinder 11, the springs 222 are squeezed and contracted, so that the springs 222 drive the mounting frame 22 to be squeezed downward to limit the position, thereby avoiding the mounting frame 22 from moving up and down in the lower cylinder 11 during use.

[0038] Working principle: Figure 1-4 As shown, first, the lower cylinder 11 is fixed at the specified position through the mounting plate 112, and then the water inlet pipe 121 and the water outlet pipe 111 are externally fixed to the external connecting pipe. After the fixing is completed, water is poured into the water inlet pipe 121. At this time, under the action of the filter cartridge 232, the liquid is primarily filtered to block larger impurities in the water. The filtered liquid passes through the filter cartridge 232 and enters the filter element 21. At this time, under the action of the filter element 21, smaller impurities in the water are adsorbed. At this time, the impurities filtered by the filter element 21 are discharged through the water outlet pipe 111.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
