Description

Technical Field

[0001] This utility model relates to the field of mine water treatment technology, specifically to a graded filtration device for mine water treatment. Background Technology

[0002] During the mining process, a large amount of mine water is generated. If the mine water is discharged directly without effective treatment, it will not only waste water resources but also cause serious pollution to the surrounding environment. Therefore, the rational treatment and reuse of mine water has always been an important issue of concern in the mining industry. At present, traditional mine water treatment equipment has many defects. Some simple filtration equipment can only perform single-level filtration, which is difficult to effectively remove various impurities, suspended solids and harmful substances from the mine water, resulting in the treated water quality failing to meet the reuse standards. While some complex treatment equipment can achieve a certain degree of staged filtration, the equipment structure is complex, the cost is high and the maintenance is difficult, which limits its practical application. In addition, existing mine water treatment equipment often relies on external power for filtration operations, which increases energy consumption and operating costs. Utility Model Content

[0003] The purpose of this utility model is to provide a graded filtration device for mine water treatment, so as to solve the problems mentioned in the background art, such as poor filtration effect of traditional filtration devices, high cost and maintenance of complex equipment, high energy consumption and high operating cost due to reliance on external power.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a graded filtration device for mine water treatment, comprising a settling chamber, a switching motor fixedly installed inside the lower end of the settling chamber, the upper end of the output shaft of the switching motor penetrating the inner bottom surface of the settling chamber, and a drive disk fixedly connected to the upper end of the output shaft of the switching motor; a pressure filtration mechanism is provided inside the upper end of the settling chamber, which achieves filtration and reuse of mine water through the underwater pressure of the mine.

[0005] The pressure filtration mechanism includes: a filter cylinder, which is snapped onto the upper surface of the drive disc, and a sealing ring is fixedly provided on the upper outer surface of the filter cylinder. A liquid storage chamber is provided inside the filter cylinder, and a secondary filter disc is provided inside the liquid storage chamber. A second liquid inlet is provided on the upper outer surface of the filter cylinder, and a first liquid inlet is provided on the upper outer surface of the settling chamber. A primary filter screen is fixedly provided on the inner surface of the end of the first liquid inlet facing the outside of the settling chamber.

[0006] The upper end of the sinking chamber is equipped with a suction and filtration mechanism, which further filters the mine water by using the suction force when water is used.

[0007] The suction filtration mechanism includes: a liquid outlet tank, which is located on the lower side surface of the filter cylinder; an upper cover is fixedly installed on the upper end of the settling chamber by bolts; a lifting ring is fixedly installed on the upper surface of the upper cover; a liquid suction pipe is fixedly installed in the center of the lower surface of the upper cover; a connecting pipe is installed in the center of the upper surface of the upper cover; and a three-stage filter element is fixedly installed in the middle section of the connecting pipe.

[0008] Preferably, the sealing ring and the sinking chamber are concentrically arranged, and the outer surface of the sealing ring is in contact with the upper inner surface of the sinking chamber, and the filter cylinder is evenly arranged on the upper surface of the drive disc.

[0009] By adopting the above technical solution, it is possible to effectively prevent mine water from leaking from the connection between the filter cylinder and the settling chamber during the filtration process, ensuring the sealing and stability of the filtration process. At the same time, the filter cylinders are evenly distributed on the drive disc, which is conducive to the drive disc driving the filter cylinders to rotate smoothly, ensuring that each filter cylinder can participate in the filtration work evenly and improving the filtration efficiency.

[0010] Preferably, the secondary filter disc and the liquid storage chamber are connected by sliding friction, and a spring is connected between the secondary filter disc and the filter cylinder, and the first liquid inlet and the second liquid inlet are at the same horizontal height.

[0011] Using the above technical solution, under the pressure of mine water, the secondary filter disc can slide flexibly in the storage chamber. The spring can buffer and regulate the filtration pressure, avoiding damage to the secondary filter disc due to excessive water pressure, and ensuring the effect and stability of secondary filtration. The first and second inlets are at the same level, which is conducive to the mine water flowing smoothly from the first inlet into the settling chamber under pressure, and then smoothly entering the storage chamber of the filter cylinder through the second inlet, reducing water flow resistance and improving filtration efficiency.

[0012] Preferably, the liquid outlet groove is positioned directly opposite the center of the drive disc, and one end of the liquid outlet groove that penetrates the outer surface of the filter cylinder is directly opposite the lower opening of the liquid suction pipe.

[0013] By adopting the above technical solution, when water is used, the equipment generates a suction force, which ensures that the mine water that has undergone preliminary filtration in the filter cartridge flows accurately from the outlet tank into the suction pipe under the action of the suction force, avoiding deviations in water flow that prevent it from entering the suction pipe smoothly, thereby ensuring the smooth progress of the suction filtration process and improving the overall filtration efficiency.

[0014] Preferably, the upper end of the liquid-drawing tube penetrates the upper end face of the upper cover, and the liquid-drawing tube and the connecting tube are threaded together.

[0015] By adopting the above technical solution, the liquid suction pipe passes through the top cover to facilitate the extraction of water from the filter cartridge, and the threaded connection makes it easy to install and disassemble the liquid suction pipe and the connecting pipe. When it is necessary to replace the third-stage filter element or maintain the liquid suction pipe and the connecting pipe, the operation is more convenient, reducing the difficulty and cost of equipment maintenance.

[0016] Preferably, the connecting tube is hollow and the connecting tube and the upper cover are concentrically arranged.

[0017] Using the above technical solution, the hollow-designed connecting pipe can provide a flow channel for mine water, allowing the mine water passing through the suction pipe to pass smoothly through the connecting pipe and be further filtered when flowing through the three-stage filter element. The connecting pipe and the upper cover are concentrically set, ensuring the symmetry and stability of the entire suction and filtration structure, which is conducive to the normal operation and installation of the equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the graded filtration equipment for mine water treatment:

[0019] 1. This equipment is equipped with a pressure filtration mechanism and a suction filtration mechanism. It performs preliminary filtration through a primary filter screen at the first liquid inlet, further filtration through a secondary filter disc in the liquid storage chamber, and filtration again through a tertiary filter element in the middle section of the connecting pipe. This achieves multi-stage filtration of mine water, effectively removing various impurities, suspended solids and harmful substances from the mine water, greatly improving the filtration effect and ensuring that the treated water quality meets the reuse standards.

[0020] 2. Compared with traditional processing equipment with complex structures, this equipment has a clever structural design. The main components such as the sinking chamber, drive plate, and filter cartridge are simple in construction, without too many complicated parts, which reduces the manufacturing cost of the equipment. At the same time, the simple structure greatly reduces the difficulty of equipment maintenance and reduces maintenance costs.

[0021] 3. The pressure filtration mechanism utilizes the underwater pressure of mine water to filter it. The switching motor drives the drive disc, causing the filter cartridges to rotate and alternately connect with the pressure environment of the mine water. This achieves the purpose of performing secondary filtration without the need for additional power equipment to provide pressure, greatly reducing energy consumption, reducing operating costs, and realizing the efficient utilization of the inherent characteristics of mine water.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a graded filtration device for mine water treatment.

[0031] Example 1

[0032] This embodiment discloses: a sinking chamber 1, a switching motor 2 is fixedly installed inside the lower end of the sinking chamber 1, and the upper end of the output shaft of the switching motor 2 penetrates the inner bottom surface of the sinking chamber 1, and a drive disk 3 is fixedly connected to the upper end of the output shaft of the switching motor 2. A pressure filtration mechanism is provided inside the upper end of the sinking chamber 1 to filter and reuse mine water through the underwater pressure of the mine.

[0033] The pressure filtration mechanism includes: a filter cylinder 4, which is snapped onto the upper surface of the drive disk 3, and a sealing ring 5 is fixedly provided on the upper outer surface of the filter cylinder 4. A liquid storage chamber 6 is provided inside the filter cylinder 4, and a secondary filter disk 7 is provided inside the liquid storage chamber 6. A second liquid inlet 10 is provided on the upper outer surface of the filter cylinder 4, and a first liquid inlet 8 is provided on the upper outer surface of the settling chamber 1. A primary filter screen 9 is fixedly provided on the inner surface of the end of the first liquid inlet 8 facing the outside of the settling chamber 1.

[0034] The closed ring 5 and the sinking chamber 1 are concentrically arranged, and the outer surface of the closed ring 5 is in contact with the upper inner surface of the sinking chamber 1. The filter cylinder 4 is evenly arranged on the upper surface of the drive disc 3.

[0035] The secondary filter disc 7 and the liquid storage chamber 6 are connected by sliding friction, and a spring is connected between the secondary filter disc 7 and the filter cylinder 4. The first liquid inlet 8 and the second liquid inlet 10 are at the same horizontal height.

[0036] When mine water flows into the equipment, it first passes through the first inlet 8 on the outer surface of the upper end of the settling chamber 1. The primary filter 9 at the first inlet 8 performs preliminary filtration of the mine water, intercepting larger particles of impurities. Subsequently, under the action of the mine water's own underwater pressure, the water flows through the first inlet 8 into the settling chamber 1, and then flows into the storage chamber 6 inside the filter cylinder 4 through the second inlet 10, which is at the same horizontal height as the first inlet 8. Since the secondary filter disc 7 and the storage chamber 6 are connected by sliding friction and a spring is connected between them, under the action of water pressure and the spring, the secondary filter disc 7 can perform secondary filtration of the mine water entering the storage chamber 6, further removing smaller particles of impurities in the water. At the same time, the switching motor 2 starts, and its output shaft drives the drive disc 3 to rotate, so that multiple filter cylinders 4 can be filled with water that has undergone secondary filtration. The sealing ring 5 is concentrically set with the settling chamber 1 and its outer surface is in contact with the inner surface of the upper end of the settling chamber 1, which can effectively prevent the mine water from leaking during the filtration process and ensure the stable operation of the filtration work.

[0037] Example 2

[0038] This embodiment discloses, based on embodiment 1, that a suction and filtration mechanism is provided at the upper end of the sink 1, which further filters the mine water by using the suction force when water is used;

[0039] The suction filtration mechanism includes: a liquid outlet tank 11, which is located on the lower side surface of the filter cylinder 4; an upper cover 12 is fixedly installed on the upper end of the lower sedimentation chamber 1 by bolts; a lifting ring 13 is fixedly installed on the upper surface of the upper cover 12; a liquid suction pipe 14 is fixedly installed in the middle of the lower surface of the upper cover 12; a connecting pipe 15 is installed in the middle of the upper surface of the upper cover 12; and a three-stage filter element 16 is fixedly installed in the middle section of the connecting pipe 15.

[0040] The liquid outlet 11 is positioned directly opposite the center of the drive disk 3, and one end of the liquid outlet 11 that penetrates the outer surface of the filter cylinder 4 is directly opposite the lower opening of the liquid suction pipe 14.

[0041] The upper end of the liquid-drawing tube 14 penetrates the upper end face of the upper cover 12, and the liquid-drawing tube 14 and the connecting tube 15 are threadedly connected.

[0042] The connecting tube 15 is hollow, and the connecting tube 15 and the upper cover 12 are concentrically arranged;

[0043] When water is used, the equipment generates suction force. At this time, the mine water, which has been initially filtered by the pressure filtration mechanism, will flow out from the liquid outlet 11 opened on the lower side surface of the filter cylinder 4. Since the liquid outlet 11 is set directly opposite the center of the drive disc 3, and one end of it that penetrates the outer surface of the filter cylinder 4 is directly opposite the lower opening of the suction pipe 14, the mine water can flow smoothly into the suction pipe 14 under the action of suction force. The three-stage filter element 16 in the middle section of the connecting pipe 15 will perform a third filtration on the incoming mine water to further improve the water quality. The upper cover 12 is fixedly installed on the upper end of the lower chamber 1 by bolts, which facilitates the installation and disassembly of the equipment. At the same time, the lifting ring 13 on its upper surface facilitates the handling, movement and suspension of the equipment. The entire suction filtration mechanism and the pressure filtration mechanism work together to achieve more comprehensive and efficient graded filtration of mine water.

[0044] When the water in the filter cylinder 4 is drawn out, the secondary filter disc 7 slides downward due to the filtration resistance and compresses the spring. At this time, the external water is drawn into the storage chamber 6. Then, as the drive disc 3 rotates, the other filter cylinder 4 rotates to face the first inlet 8 and continues to be drawn in for tertiary filtration and output water. Meanwhile, the secondary filter disc 7 inside the rotated filter cylinder 4 gradually moves up and down under the support of the compressed spring to filter the mine water, thereby improving the overall filtration efficiency.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
