Description

Technical Field

[0001] This utility model relates to the field of food and beverage production, and in particular to a multi-stage precision filtration device for the production of strontium-rich water. Background Technology

[0002] As people's living standards improve and their awareness of health deepens, the requirements for drinking water quality are becoming increasingly stringent. Strontium-rich water, as a type of drinking water rich in strontium and with various health benefits, has received widespread attention in the market and is favored by consumers. Strontium plays an important role in human physiological processes, such as helping bone development and maintaining cardiovascular health. Therefore, the production and supply of strontium-rich water has become an important link in meeting people's health needs.

[0003] In the production process of strontium-rich water, filtration is a key step to ensure that the water quality meets the standards. Raw water often contains impurities of various particle sizes, such as silt, algae, suspended solids, and some tiny particles. These impurities not only affect the taste and appearance of the water, but may also pose a potential threat to human health. In order to remove these impurities and ensure the purity and quality of strontium-rich water, reliable filtration devices are required.

[0004] Traditional filtration devices have certain limitations in design and function. Some filtration devices have few filtration stages and usually only use a single or simple filtration method, which is difficult to effectively remove impurities of different particle sizes, resulting in poor filtration effect. Moreover, some filtration devices are usually installed by bolts, so installation and disassembly require removing each bolt one by one, which is not convenient. When maintenance, repair or replacement of filter elements is required, the operation process is cumbersome, which consumes a lot of time and manpower, affecting production efficiency and normal use of equipment, and has poor practicality. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a multi-stage precision filtration device for the production of strontium-rich water, which aims to solve the problem in the prior art that "traditional filtration devices have few filtration stages and a single filtration method, making it difficult to effectively remove impurities of different particle sizes, resulting in poor filtration effect".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage precision filtration device for strontium-rich water production, comprising a filter cylinder and a detachable mounting cover installed at the bottom of the filter cylinder. The filter cylinder contains a filter assembly for multi-stage filtration. An inlet pipe connecting to the interior is located near the upper end of the front outer wall of the filter cylinder, and an outlet pipe is located near the lower end of the front outer wall of the filter cylinder. The filter assembly includes a first filter cylinder, with two sets of mounting slots symmetrically opened on the top left and right sides. A third filter cylinder is movably inserted into the middle of the first filter cylinder. Mounting blocks are fixedly connected to the left and right sides of the third filter cylinder near its top. The two sets of mounting blocks are respectively inserted into the inner walls of the two sets of mounting slots. The top of the third filter cylinder also has two sets of mounting slots symmetrically opened. A second filter cylinder is movably inserted into the middle of the third filter cylinder. The mounting cover is fixedly installed to the filter cylinder via a limiting component.

[0007] As a further description of the above technical solution: The limiting component includes two sets of guide frames and two sets of limiting grooves. The two sets of limiting grooves are symmetrically opened on the left and right outer walls of the filter cylinder near the bottom. The bottom of the filter cylinder is provided with positioning grooves on both the front and rear sides. Positioning blocks are fixedly connected to the front and rear outer walls of the mounting cover. The two sets of positioning blocks are respectively inserted into the inner walls of the two sets of positioning grooves to achieve the initial positioning of the mounting cover and the filter cylinder.

[0008] As a further description of the above technical solution: The upper surface of the mounting cover has a sealing groove near the periphery, and a sealing ring is installed on the inner wall of the sealing groove.

[0009] As a further description of the above technical solution: The left and right sides of the filter cartridge two are also fixedly connected to the top of the filter cartridge two. The two sets of mounting blocks at the top of the filter cartridge two are respectively inserted into the inner walls of the two sets of mounting slots at the top of the filter cartridge three. The middle part of the filter cartridge two is inserted through the outer wall of the water inlet pipe.

[0010] As a further description of the above technical solution: Both sets of guide frames are designed in an L-shape.

[0011] As a further description of the above technical solution: Both sets of guide frames have fixed limit blocks on their opposite faces near the top. The two sets of limit blocks are respectively inserted into the inner walls of the two sets of limit grooves. The bottom of the mounting cover is symmetrically fixed with two sets of fixing blocks in the left-right direction. A bidirectional screw is rotatably connected between the two sets of fixing blocks, and both ends of the bidirectional screw extend to the outside of the fixing blocks.

[0012] As a further description of the above technical solution: Both ends of the bidirectional screw are fixedly connected to anti-slip knobs, and the outer wall of the anti-slip knobs is provided with anti-slip texture.

[0013] As a further description of the above technical solution: The outer wall of the bidirectional screw is symmetrically threaded with two sets of guide blocks along its axial direction. The two sets of guide frames form sliding contact with the lower surface of the mounting cover, and the opposite ends of the bottom of the two sets of guide frames are fixedly connected to the top of the two sets of guide blocks.

[0015] 2. In this utility model, initial positioning is achieved by aligning the positioning block with the positioning groove and inserting it. Then, the anti-slip knob is rotated to drive the bidirectional screw, which in turn drives the guide frame and the limiting block to insert into the limiting groove, thus completing the installation and fixing. When disassembling, the mounting cover can be easily removed by reversing the operation. This makes maintenance or replacement quick and convenient, saves maintenance time and labor costs, improves the efficiency of subsequent equipment maintenance and production efficiency, and ensures the continuity and stability of the strontium-rich water production process.

[0018] 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.

[0019] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a multi-stage precision filtration device for producing strontium-rich water. It includes a filter cylinder 1 for providing a strontium-rich water filtration chamber and supporting the installation of various components, and a detachable mounting cover 2 installed at the bottom of the filter cylinder 1. The filter cylinder 1 contains a multi-stage filtration assembly 4, which performs multi-stage progressive filtration of the raw water to remove impurities of different particle sizes, ensuring the purity of the strontium-rich water. An inlet pipe 23, connecting to the interior of the filter cylinder 1, is located near the upper end of the front outer wall of the filter cylinder 1. The inlet pipe 23 transports the raw water to be filtered into the filter cylinder 1. An outlet pipe, located near the lower end of the front outer wall of the filter cylinder 1, discharges the qualified strontium-rich water after multi-stage filtration by the filtration assembly 4. The filtration assembly 4 includes a filter cylinder... 41. Filter cartridge 1 is used for preliminary filtration of larger suspended particles in the raw water, such as silt and algae. The top of filter cartridge 1 has two sets of mounting grooves 42 symmetrically provided on the left and right sides to provide installation positioning reference and adapt to the installation of filter cartridge 3 45. Filter cartridge 3 45 is movably inserted into the middle of filter cartridge 1 41 for secondary fine filtration of the water after preliminary filtration by filter cartridge 1 41 and interception of medium-sized impurities. On the left and right sides near the top of filter cartridge 3 45, mounting blocks 43 are fixedly connected to cooperate with the mounting grooves 42 of filter cartridge 1 41 to achieve precise positioning and installation of filter cartridge 3 45 in filter cartridge 1 41. The two sets of mounting blocks 43 are respectively inserted into the inner walls of the two sets of mounting grooves 42, and the radial rotation and axial displacement of filter cartridge 3 45 in filter cartridge 1 41 are restricted by the insertion and cooperation.

[0020] Furthermore, the top of filter cartridge 3 45 is also symmetrically provided with two sets of mounting grooves 42 for fitting filter cartridge 2 44 and providing the same positioning reference. Filter cartridge 2 44 is movably inserted into the middle of filter cartridge 3 45 for final precision filtration of the water filtered by filter cartridge 3 45, ensuring that the impurity content of the effluent meets the strontium-rich water standard. The upper surface of the mounting cover 2 is provided with a sealing groove 22 near the outer periphery to accommodate the sealing ring 21 and provide installation space for the sealing ring 21. The inner wall of the sealing groove 22 is equipped with a sealing ring 21 to fill the gap between the filter cartridge 1 and the mounting cover 2 and prevent the filtered water inside the device from leaking from the bottom gap. The left and right sides of filter cartridge 2 44 are also fixedly connected with mounting grooves 42 for mounting with filter cartridge 3 45 near the top. The mounting blocks 43 are used to precisely position and install filter cartridge 2 44 inside filter cartridge 3 45. The two sets of mounting blocks 43 at the top of filter cartridge 2 44 are respectively inserted into the inner walls of the two sets of mounting grooves 42 at the top of filter cartridge 3 45. The insertion and cooperation ensures the installation stability of filter cartridge 2 44 inside filter cartridge 3 45. The middle part of filter cartridge 2 44 is inserted through the outer wall of water inlet pipe 23 to transport raw water into filter cartridge 2 44 for the first filtration. The size of the filter holes of filter cartridge 2 44, filter cartridge 3 45 and filter cartridge 1 41 gradually decreases from the inside to the outside, so that precise multi-stage filtration can be performed from the inside to the outside. The mounting cover 2 is fixedly installed with the filter cartridge 1 through the limiting component 3 used to realize the quick fixing and disassembly of the mounting cover 2 and the filter cartridge 1 and to ensure the sealing stability of the mounting cover 2.

[0021] Reference Figure 1 , Figure 4 and Figure 5 The limiting component 3 includes two sets of guide frames 31 that drive two sets of limiting blocks 32 to move, and two sets of limiting grooves 33 that cooperate with the two sets of limiting blocks 32 for quick installation and limiting. The two sets of limiting grooves 33 are symmetrically opened on the left and right outer walls of the filter cylinder 1 near the bottom. The axial separation of the mounting cover 2 from the filter cylinder 1 is limited by the cooperation of the limiting blocks 32 and the limiting grooves 33. The bottom end of the filter cylinder 1 has positioning grooves 34 on both the front and rear sides to provide a preliminary positioning reference and assist the mounting cover 2 in quickly finding the installation position. The front and rear outer walls of the cover 2 are fixedly connected with positioning blocks 35 for cooperating with positioning grooves 34 to achieve initial positioning of the cover 2 and the filter cylinder 1. The two sets of positioning blocks 35 respectively form an insertion fit with the inner walls of the two sets of positioning grooves 34 to achieve initial positioning of the cover 2 and the filter cylinder 1, so that the limiting block 32 and the limiting groove 33 can be quickly connected. The two sets of guide frames 31 are both set in L shape. The L shape setting can realize the connection between the guide frame 31 and the guide block 36 and drive the limiting block 32 to be inserted into the limiting groove 33.

[0022] Furthermore, each of the two sets of guide frames 31 has a fixedly connected limiting block 32 near its top surface, which is used to insert into the limiting groove 33 and fix the mounting cover 2 to the filter cylinder 1. The two sets of limiting blocks 32 respectively form an insertion fit with the inner wall of the two sets of limiting grooves 33. The bottom end of the mounting cover 2 is symmetrically fixedly connected with two sets of fixing blocks 38 in the left-right direction to provide support. The two sets of fixing blocks 38 are rotatably connected to each other, and a bidirectional screw 37 is used to transmit rotational power and drive the guide block 36 to move. Both ends of the bidirectional screw 37 extend to the outside of the fixing block 38. Both ends of the bidirectional screw 37 are fixedly connected to anti-slip knobs 39. The outer wall of the anti-slip knobs 39 is provided with anti-slip texture. The anti-slip knobs 39 can easily drive the bidirectional screw 37 to rotate. The outer wall of the bidirectional screw 37 is symmetrically threaded along its axis with two sets of guide blocks 36 for converting the rotational motion of the bidirectional screw 37 into linear motion and driving the guide frame 31 to move. The two sets of guide frames 31 respectively form sliding contact with the lower surface of the mounting cover 2. The opposite ends of the bottom of the two sets of guide frames 31 are fixedly connected to the top ends of the two sets of guide blocks 36 respectively.

[0023] Working principle: In use, first align the positioning block 35 with the positioning grooves 34 on the front and rear sides of the bottom of the filter cylinder 1 and insert it to achieve initial positioning. Then, rotate the anti-slip knob 39 to drive the bidirectional screw 37 to rotate. The bidirectional screw 37 is threadedly connected to the two sets of guide blocks 36, so that the guide blocks 36 move inward synchronously, converting the rotational motion of the bidirectional screw 37 into linear motion. At the same time, it drives the two sets of L-shaped guide frames 31 to move relative to each other synchronously, so that the two sets of limiting blocks 32 are inserted into the two sets of limiting grooves 33 respectively, completing the quick installation and fixing of the mounting cover 2 and the filter cylinder 1. At this time, the sealing ring 21 in the sealing groove 22 on the outer surface of the mounting cover 2 fills the gap between the two to prevent leakage.

[0024] During filtration, the raw water to be filtered is delivered to the interior through the inlet pipe 23 at the upper front of the filter cylinder 1. The outer wall of the inlet pipe 23 is inserted through the middle of the filter cylinder 2 44. The raw water first enters the filter cylinder 2 44. The filter cylinder 2 44 is positioned by the mounting blocks 43 on the left and right sides of the top and the mounting groove 42 at the top of the filter cylinder 3 45, which performs the final precision filtration of the raw water. Then the water flows into the filter cylinder 3 45. The filter cylinder 3 45 is positioned by the mounting blocks 43 on the left and right sides of the top and the mounting groove 42 at the top of the filter cylinder 1 41, which performs the secondary fine filtration of the water filtered by the filter cylinder 2 44. Then the water flows into the filter cylinder 1 41, which performs the final filtration of the water. The filter holes of the filter cylinder 2 44, filter cylinder 3 45 and filter cylinder 1 41 gradually decrease from the inside to the outside, realizing precision multi-stage filtration. Finally, the filtered water that meets the strontium-rich water standard is discharged through the outlet pipe at the lower front of the filter cylinder 1, completing the filtration.

[0025] When maintenance is required, the anti-slip knob 39 is rotated in the opposite direction, which drives the bidirectional screw 37 to rotate in the opposite direction. This causes the two sets of guide blocks 36 to move the guide frame 31 in the opposite direction in sync. The limit block 32 disengages from the limit groove 33, allowing the installation cover 2 to be removed for inspection or replacement of the filter assembly 4. The operation is convenient and improves the efficiency and convenience of subsequent maintenance.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
