Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, specifically an automatic water glass filtration device. Background Technology

[0002] In the production and processing of water glass, filtration is a key step in ensuring product quality, directly affecting the purity and performance stability of the finished product.

[0003] Currently, most mainstream water glass filtration equipment on the market is based on technologies such as mechanical filtration, centrifugal separation, or chemical treatment. However, existing equipment generally suffers from high structural complexity, high maintenance costs, and high energy consumption. For example, mechanical filtration devices often require frequent cleaning or replacement due to easy clogging of the filter screen, leading to increased downtime. While centrifugal separation equipment can effectively remove some impurities, its high energy consumption and wear of precision components raise long-term operating costs. In addition, some equipment has low efficiency in handling impurities, especially in separating micron-sized particles or colloidal contaminants, resulting in the risk of residual impurities in the filtered water glass, which in turn affects the performance requirements of downstream applications (such as precision casting and coating preparation). Existing technologies also face the challenge of insufficient adaptability. Equipment is often designed for water glass with specific viscosities or compositions, and the filtration effect is prone to deviation when raw material parameters fluctuate, making it difficult to meet diversified production needs.

[0004] Therefore, there is a need to develop an automated filtration device that is structurally simplified, energy-efficient, and highly adaptable. Through technological innovation, we can overcome the bottlenecks in efficiency, cost, and compatibility of existing equipment and provide a more efficient and reliable production solution for the water glass industry.

Detailed Implementation

[0024] 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.

[0025] This utility model provides an automatic water glass filtration device, the overall structure of which is as follows: Figure 1 As shown, the system mainly comprises two parts: a filter body 1 and a drive mechanism 2. The filter body 1 consists of a multi-stage filter assembly 3 and a separation chamber 4. The multi-stage filter assembly 3 is positioned above and communicates with the separation chamber 4. A sludge discharge port 8 is located at the bottom of the separation chamber 4 and is connected to an external sewage pipe via an elastic seal 9. The drive mechanism 2 includes a rotating shaft 10 and a drive motor 11. The rotating shaft 10 passes through the separation chamber 4 and extends into the multi-stage filter assembly 3. The drive motor 11 is fixedly installed on one side of the separation chamber 4 and is connected to the rotating shaft 10 via a coupling. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] The multi-stage filtration assembly 3 includes a first filter screen 5, a second filter screen 6, and a third filter screen 7, arranged sequentially from top to bottom and fixed to the top inner wall of the separation chamber 4 via a snap-fit ​​structure. The first filter screen 5 has a pore size of 10-20 mesh, used for initial interception of larger particulate impurities; the second filter screen 6 has a pore size of 30-50 mesh, used for further filtration of medium-sized particulate impurities; and the third filter screen 7 has a pore size of 60-80 mesh, used for fine filtration of tiny particulate impurities. Sealing rings are provided at the edges of the first filter screen 5, the second filter screen 6, and the third filter screen 7. These sealing rings are embedded in an annular groove on the inner wall of the separation chamber 4 to prevent liquid leakage from the filter screen edges. The specific structure of the multi-stage filtration assembly 3 is as follows: Figure 2 As shown, the three filter screens are fixed by a snap-fit ​​structure, which makes them easy to disassemble and replace. At the same time, the design of the sealing ring ensures that liquid will not leak from the edge of the filter screen during the filtration process, thereby improving the filtration efficiency.

[0027] The separation chamber 4 includes an upper chamber and a lower chamber, which are connected by threads. The inner wall of the upper chamber is equipped with guide plates arranged in a spiral pattern to guide the water glass tangentially into the lower chamber. The bottom of the lower chamber has a conical slag collection area 12, with a slag discharge port 8 at its center for collecting impurities filtered from the filter screen. The specific structure of the separation chamber 4 is as follows: Figure 3 As shown, the design of the guide plate enables the water glass to form a vortex motion after entering the separation chamber 4, which accelerates the settling of impurities. The design of the conical slag collection area 12 can effectively concentrate impurities and discharge them through the slag discharge port 8, avoiding the impact of impurity accumulation on filtration efficiency.

[0028] The rotating shaft 10 includes a main shaft and multiple stirring blades 13. The two ends of the main shaft are connected to the upper and lower ends of the separation chamber 4 via bearings. The stirring blades 13 are evenly distributed on the outer circumference of the main shaft, and their length gradually decreases from top to bottom to accommodate different filtration heights. The surface of the stirring blades 13 is coated with a wear-resistant coating to improve their service life. The specific structure of the rotating shaft 10 and the stirring blades 13 is as follows: Figure 3 As shown, the design of the stirring blades 13 causes the water glass to form a vortex motion within the separation chamber 4, thereby accelerating the separation and sedimentation of impurities. The length of the stirring blades 13 gradually decreases from top to bottom, which can better adapt to the filtration requirements of different heights, while the wear-resistant coating design extends the service life of the stirring blades 13.

[0029] The drive motor 11 is connected to the rotating shaft 10 via a coupling. Keyways are provided at both ends of the coupling, and flat keys are inserted into the keyways to achieve synchronous rotation of the drive motor 11 and the rotating shaft 10. The housing of the drive motor 11 is fixed to the outside of the separation chamber 4 with four bolts evenly distributed around the drive motor 11. The drive motor 11 drives the rotating shaft 10 to rotate via the coupling, thereby causing the stirring blades 13 to perform stirring operations within the separation chamber 4, further accelerating the separation and sedimentation of impurities in the water glass.

[0030] The elastic seal 9 includes a rubber sleeve and a spring. The rubber sleeve is fitted onto the outside of the slag discharge port 8. One end of the spring is fixedly connected to the inner wall of the rubber sleeve, and the other end is fixedly connected to the outer wall of the slag discharge port 8, providing a certain buffering effect during the slag discharge process. The specific structure of the elastic seal 9 is as follows: Figure 4 As shown, the design of the rubber sleeve and spring can provide a buffering effect during the slag discharge process, while ensuring the seal between the slag discharge port 8 and the external sewage pipe to prevent liquid leakage.

[0031] The upper chamber has an inlet 14 at its top, with threads on its inner wall for connection to an external feed pipe. The lower chamber has an outlet 15 on its side, with a flow meter below the outlet 15 to monitor the flow rate of the filtered water glass. The inlet 14 allows water glass to smoothly enter the separation chamber 4, while the outlet 15 facilitates the outflow of filtered water glass. The flow meter allows for real-time monitoring of the filtered water glass flow rate, ensuring the stability and reliability of the filtration process.

[0032] The outer wall of the separation chamber 4 is equipped with an observation window 16, which is made of transparent and corrosion-resistant material and is used to observe the working status inside the separation chamber 4 in real time. Its edges are bonded and fixed to the outer wall of the separation chamber 4 with sealant. The design of the observation window 16 allows the operator to observe the working status inside the separation chamber 4 in real time, thereby promptly detecting and handling abnormal situations.

[0033] Vibrators 17 are installed below the first filter screen 5, the second filter screen 6, and the third filter screen 7. The vibrators 17 are fixed to the inner wall of the separation chamber 4 by screws to prevent the filter screens from clogging. The design of the vibrators 17 can effectively prevent the filter screens from clogging, thereby improving filtration efficiency and the operational stability of the equipment.

[0034] In actual use, water glass enters the separation chamber 4 through the inlet 14 and is first filtered by the multi-stage filtration components 3. The first filter screen 5 initially intercepts larger particles of impurities, the second filter screen 6 further filters medium-sized particles, and the third filter screen 7 performs fine filtration of tiny particles. The filtered water glass enters the upper chamber of the separation chamber 4 and is guided tangentially into the lower chamber by the guide plate, forming a vortex motion. The drive motor 11 drives the rotating shaft 10 to rotate through the coupling, causing the stirring blades 13 to stir within the separation chamber 4, further accelerating the separation and sedimentation of impurities. Impurities are concentrated in the conical slag collection area 12 and discharged through the slag discharge port 8, while the filtered water glass flows out through the discharge port 15. The flow meter monitors the flow rate of the filtered water glass in real time. The entire filtration process is highly efficient and stable, and the connection between the components is simple and reliable, facilitating disassembly and maintenance, significantly reducing the manufacturing cost and operating energy consumption of the equipment.

[0035] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific operating principle and implementation steps of this utility model is provided in conjunction with a specific application scenario.

[0036] Initially, water glass enters the separation chamber 4 through the external feed pipe and inlet 14. A threaded structure is provided on its inner wall to ensure a tight connection with the external feed pipe and prevent liquid leakage. After entering the separation chamber 4, the water glass first reaches the multi-stage filtration assembly 3. Figure 2As shown, the multi-stage filtration assembly 3 includes a first filter screen 5, a second filter screen 6, and a third filter screen 7, arranged sequentially from top to bottom and fixed to the top inner wall of the separation chamber 4 via a snap-fit ​​structure. The first filter screen 5 has a pore size of 10-20 mesh, used to intercept larger particulate impurities; the second filter screen 6 has a pore size of 30-50 mesh, further filtering medium-sized particulate impurities; and the third filter screen 7 has a pore size of 60-80 mesh, used for fine filtration of tiny particulate impurities. Each filter screen has a sealing ring embedded in its edge, which is fitted into an annular groove in the inner wall of the separation chamber 4 to prevent liquid leakage from the filter screen edges. This staged filtration design significantly improves filtration efficiency while facilitating filter screen disassembly and replacement.

[0037] After preliminary treatment by the multi-stage filtration assembly 3, the water glass flows into the upper chamber of the separation chamber 4. The inner wall of the upper chamber is equipped with spirally distributed guide plates, which guide the water glass tangentially into the lower chamber, creating a vortex motion within the lower chamber. This vortex motion helps accelerate the sedimentation of impurities, thereby improving the separation effect. The drive motor 11 drives the rotating shaft 10 to rotate via a coupling. The rotating shaft 10 passes through the separation chamber 4 and extends into the multi-stage filtration assembly 3. The stirring blades 13 on the rotating shaft 10 are evenly distributed on the outer circumference of the main shaft, with their length gradually decreasing from top to bottom to accommodate different filtration heights. The surface of the stirring blades 13 is coated with a wear-resistant coating, effectively extending their service life during stirring. The rotation of the stirring blades 13 further enhances the vortex motion of the water glass within the separation chamber 4, thereby accelerating the separation and sedimentation of impurities.

[0038] A conical slag collection area 12 is provided at the bottom of the lower cavity of the separation chamber 4, such as... Figure 3 As shown, the conical slag collection zone 12 is designed to concentrate impurities near the slag discharge port 8, preventing impurity accumulation from affecting filtration efficiency. It is connected to the external drain pipe via an elastic seal 9. The elastic seal 9 includes a rubber sleeve and a spring. The rubber sleeve is fitted onto the outside of the slag discharge port 8, one end of the spring is fixedly connected to the inner wall of the rubber sleeve, and the other end is fixedly connected to the outer wall of the slag discharge port 8. This design provides a buffering effect during slag discharge while ensuring a tight seal between the slag discharge port 8 and the external drain pipe, preventing liquid leakage.

[0039] During the filtration process, the vibrator 17 is fixed to the inner wall of the separation chamber 4 with screws. The design of the vibrator 17 effectively prevents clogging of the first filter screen 5, the second filter screen 6, and the third filter screen 7, thereby improving filtration efficiency and equipment operational stability. Furthermore, the outer wall of the separation chamber 4 is equipped with an observation window 16, made of transparent, corrosion-resistant material, whose edges are bonded to the outer wall of the separation chamber 4 with sealant. Operators can observe the working status inside the separation chamber 4 in real time through the observation window 16, promptly identifying and addressing any abnormalities.

[0040] After being processed in separation chamber 4, the water glass flows out through outlet 15, below which a flow meter is installed to monitor the flow rate of the filtered water glass. The flow meter allows for real-time monitoring of the filtered water glass flow rate, ensuring the stability and reliability of the filtration process. The entire filtration process is highly efficient and stable, with simple and reliable connections between components, facilitating disassembly and maintenance, and significantly reducing equipment manufacturing costs and operating energy consumption.

[0041] As can be seen from the above steps, this device achieves efficient separation and sedimentation of impurities in water glass through the multi-stage filtration assembly 3, the vortex motion within the separation chamber 4, and the auxiliary stirring of the stirring blades 13. The design of the conical slag collection zone 12 and the elastic seal 9 further optimizes the centralized discharge of impurities and the sealing performance, while the application of the vibrator 17 effectively prevents filter screen clogging and improves the overall operational stability of the equipment. These designs work together to ensure the high efficiency, reliability, and economy of the water glass filtration process.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
