Description

Technical Field

[0001] This utility model relates to the field of emulsion filtration and purification technology, specifically to a filtration and purification device for a high-stability emulsion drilling rig. Background Technology

[0002] Emulsion drilling rigs are drilling machines that use emulsion as their working medium, primarily for drilling operations in mines such as coal mines. They are powered by an emulsion hydraulic pump station, converting hydraulic energy into mechanical energy to perform drilling and anchor bolt installation. The emulsion is a high-performance semi-synthetic metalworking fluid, particularly suitable for processing aluminum and its alloys, but not for lead-containing materials such as some brass and tin metals. The product has a long service life and is completely unaffected by oil leaks or contamination; it is best prepared with soft water. The emulsion uses a chlorine-free, specially formulated solution to address various problems encountered during the processing of aluminum and its alloys (such as chip adhesion, tool wear, poor workpiece surface finish, and surface contamination).

[0003] The emulsion contains solid contaminants, which are removed by a filtration and purification device to ensure that the emulsion maintains stable physicochemical properties. The original emulsion filtration device has a single effect and first filters large particles when filtering the emulsion. After long-term use, the filter screen becomes clogged, resulting in poor filtration effect. The filter structure cannot be quickly disassembled and replaced when filtering the emulsion, resulting in excessive replacement time and affecting subsequent use. Utility Model Content

[0014] The beneficial effects of the embodiments of this utility model are as follows:

[0015] In this invention, a double-layer filter element is used, employing multiple sets of second filter elements to filter the emulsion separately, reducing the distribution of impurities on the filter elements and increasing their lifespan while achieving dual filtration of the emulsion. A fixing ring is added to the outer layer of the first filter element, which is inserted into the connecting groove for quick disassembly and fixation. The second filter element is inserted through holes and fixed to the mounting plate by snap-fit ​​rings. The above configuration uses a double filter element to purify the emulsion, and the fixing ring and snap-fit ​​ring allow for quick fixation and disassembly of the filter elements. In addition, a sliding strip is added to the side of the double-layer filter screen, which slides the filter screen in the sliding groove for easy disassembly and installation. A reverse air jet pipe is installed on the partition plate, which sprays out impurities from the upper part of the filter screen, reducing the concentration of impurities on the upper part of the filter screen and increasing its lifespan. The above configuration uses the reverse air jet pipe to clean the upper part of the filter screen, reducing the concentration of impurities. Attached Figure Description

[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-3 As shown, it illustrates a filtration and purification device for a high-stability emulsion drilling rig according to an embodiment of the present invention, comprising: a storage tank 1, connecting grooves 2 fixedly provided on both sides of the inner wall of the storage tank 1, and a connecting hole 3 fixedly provided at the rear end of the storage tank 1.

[0029] The first filter element 11 is fixedly connected inside the storage tank 1. A fixing ring 12 is fixedly installed on the upper end of the first filter element 11. A support plate 13 is fixedly connected inside the first filter element 11, and a mounting plate 14 is fixedly connected to the upper end of the support plate 13. A hole 15 is fixedly opened inside the mounting plate 14. A second filter element 16 is fixedly connected inside the hole 15, and a snap ring 17 is fixedly installed on the upper end of the second filter element 16.

[0030] For example, a connecting pipe 4 is fixedly installed at the front end of the storage tank 1, and an emulsion tank 5 is fixedly installed at the front end of the connecting pipe 4. A drain pipe 6 is fixedly installed at the front end of the emulsion tank 5. A conveying pipe 7 is fixedly connected inside the storage tank 1. A sealing cover 8 is fixedly connected to the top of the storage tank 1, and a pressure gauge 9 is fixedly installed above the sealing cover 8. A switch screw 10 is fixedly installed at the front end of the sealing cover 8.

[0031] For example, such as Figure 3 As shown, the connecting groove 2 is symmetrically installed on the left and right sides of the inner wall of the storage tank 1 with the storage tank 1 as the center reference, and the fixing ring 12 is symmetrically installed on the left and right sides of the first filter element 11 with the first filter element 11 as the center reference.

[0032] For example, such as Figure 3 As shown, the support plate 13 and the mounting plate 14 are fixedly connected. There are four holes 15. The second filter element 16 is interlocked with the holes 15. The second filter element 16 is interlocked with the holes 15 through the snap ring 17.

[0033] For example, such as Figure 2 As shown, four drain pipes are fixedly installed at the lower end of the conveying pipe 7, the connecting groove 2 and the fixing ring 12 form an interlocking connection, and a handle is fixedly installed at the upper end of the sealing cover 8.

[0034] In some examples, the delivery pipe 7 is connected to the connecting pipe 21 via a flange. The emulsion enters the storage tank 1 through the delivery pipe 7. Four pipes branch off from the lower end of the delivery pipe 7, corresponding to four second filter elements 16 respectively. The emulsion enters each second filter element 16 through the branches of the delivery pipe 7. The emulsion undergoes initial filtration and purification within the second filter element 16. The second filter element 16 is covered by a first filter element 11, and the emulsion then flows through the first filter element 11 for a second filtration and purification (double filtration). The filtered and purified emulsion falls to the bottom of the storage tank 1. The emulsion flows from the bottom of the storage tank 1 into the emulsion tank 5 through the side connecting pipe 4. When removing and replacing the filter element, the switch screw 10 is opened, then the sealing cover 8 is opened, and the delivery pipe 7 is rotated to allow the emulsion to flow from the connecting pipe 21. The flange connection of 1 is removed, and the mounting plate 14 is pulled outward. Pulling the mounting plate 14 will cause the retaining ring 12 to come out of the connecting groove 2 inside the storage tank 1. The bottom of the connecting groove 2 is equipped with a magnetic plate for additional magnetic fixation of the retaining ring 12. This magnetic force needs to be overcome during disassembly. The retaining ring 12 is installed at the outer end of the first filter element 11. When the retaining ring 12 is pulled out, the entire first filter element 11 assembly (including its internal support plate 13 and mounting plate 14) will be removed from the storage tank 1 at the same time. The first filter element 11 has a support plate 13 inside for fixing the position of the mounting plate 14. The second filter element 16 is located inside the first filter element 11 and is independent of the first filter element 11. Pull the second filter element 16 directly upward to disassemble the second filter element 16.

[0035] For example, such as Figure 4 As shown, this invention illustrates a filtration and purification device for a high-stability emulsion drilling rig, comprising a storage tank 1 with a housing 18 fixedly connected to its rear end, an input pipe 19 fixedly installed on the top of the housing 18, outlets 20 fixedly opened on both sides of the housing 18, and a connecting pipe 21 fixedly installed at the lower end of the outlets 20, partitions 22 fixedly installed on both sides inside the housing 18, and a sliding groove 23 fixedly opened at the upper end of the partitions 22, an air pump 24 fixedly installed on the inner wall of the partitions 22, and an air jet pipe 25 fixedly installed at the upper end of the air pump 24, a frame 26 fixedly connected to the inner side of the air jet pipe 25, and sliding strips 27 fixedly installed on both sides of the frame 26, and a filter screen 28 fixedly installed inside the frame 26.

[0036] For example, such as Figure 4 As shown, the outlet 20 is symmetrically installed on the front and rear sides of the housing 18 with the housing 18 as the center reference, and the partition 22 is symmetrically installed on the front and rear sides of the interior of the housing 18 with the interior of the housing 18 as the center reference. The partition 22 is L-shaped.

[0037] For example, such as Figure 4 As shown, the upper end of the partition 22 is inclined, the slide groove 23 and the slide bar 27 form a sliding connection, the jet pipe 25 is inclined upward, and the filter screen 28 is a double-layer structure.

[0038] In some examples, the input pipe 19 is connected to the emulsion tank, and the emulsion is input into the tank 18 through the input pipe 19. Two partitions 22 are vertically installed inside the tank 18, dividing the internal space of the tank 18 into three areas (a central filtration area and two impurity collection areas on both sides). Each partition 22 has a groove 23 at its upper end. Sliding strips 27 are installed on both sides of the frame 26 (with built-in filter 28). A dynamic connection is achieved by embedding the sliding strips 27 on both sides of the frame 26 into the grooves 23 at the upper end of the partition 22, thereby installing the double-layer filter 28 above the central filtration area of ​​the tank 18. The emulsion enters the tank 18 through the input pipe 19 and falls directly into the central filtration area. On the double-layer filter screen 28 of the filter zone, the filter screen 28 performs preliminary filtration of large impurities in the emulsion. In order to reduce the accumulation of impurities on the filter screen 28 and extend its service life, an air pump 24 is installed on the inner side of each partition 22 (the side facing the filter screen 28). The air pump 24 is connected to a jet pipe 25. The jet pipe 25 is designed at an inclined angle, and its nozzle faces the filter screen 28. When working, the air pump 24 blows air to the filter screen 28 through the inclined jet pipe 25. The inclined airflow blows up the impurities intercepted on the filter screen 28 and blows them off to both sides (the partition area formed by the partition 22 and the side wall of the box 18). The blown-off impurities are finally stored in the collection areas on both sides of the box 18.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
