Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, specifically, it relates to an integrally cast filter plate for filter beds. Background Technology

[0002] Integral cast-in-place filter plates are an important component in filter beds. Compared with traditional filter plate forms, they have unique advantages and characteristics, playing a key role in many water treatment and other related filter bed applications. Integral cast-in-place filter plates are formed in one piece on site, avoiding the gaps and loose joints that may exist when splicing traditional precast filter plates. This makes the entire filter plate structure form a stable whole, which can better withstand the impact of water flow and the pressure of filter media in the filter bed.

[0003] Chinese patent CN214808919U discloses an integral filter plate for water treatment, including a filter screen fixing frame, a first filter screen, a second filter screen, filter screen fastening clips, a first filter screen positioning groove, a first scraper, clip force-applying protrusions, and fixing connecting ears. When water flows into the filter screen fixing frame, it first passes through the first filter screen, where larger particles such as sand and gravel are intercepted. The water then continues to pass through the second filter screen, which further intercepts finer floating objects and other impurities. This double-layer filtration effectively removes various types of impurities from the water flow. The device effectively removes impurities, achieving a good primary treatment effect and improving the efficiency and quality of subsequent water treatment processes. However, although it employs a dual-layer filtration system, which theoretically enhances the filtration effect, in reality, some impurities with particle sizes between the two filter screens may not be filtered thoroughly. For example, when there are particles in the water that are slightly smaller than the first filter screen's pore size and slightly larger than the second filter screen's pore size, these particles may accumulate between the two filter screens. Over time, this not only affects the filtration efficiency but may also increase water flow resistance and even damage the filter screen structure.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integral cast filter plate for filter beds, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A monolithic cast filter plate for a filter bed includes: an outer frame, two through slots at the front end of the outer frame, a first filter plate and a second filter plate respectively connected in the two through slots, impact plates connected to the left and right sides of the surfaces of the first filter plate and the second filter plate, and both the first filter plate and the second filter plate are inclined, and vibration mechanisms connected to the left and right sides of the bottom ends of the first filter plate and the second filter plate.

[0008] Optionally, the inner wall of the outer frame is provided with grooves on both the left and right sides, which are located below the first filter plate and the second filter plate, respectively, and the vibration mechanism is located in the grooves.

[0009] Optionally, the vibration mechanism includes a spring fixedly connected to the bottom end of the groove, and a support plate fixedly connected to the top end of the spring, the top end of the support plate abutting against the bottom end of the first filter plate.

[0010] Optionally, the left and right sidewalls of the outer frame are each connected to a fixing block, and the surface of the fixing block is provided with a threaded hole.

[0011] Optionally, a fixing pin is connected to the top of the outer frame, and the fixing pin penetrates the surface of the outer frame.

[0012] Optionally, the fixing pin passes through the outer frame surface, the first filter plate, the support plate below the first filter plate, the second filter plate, and the support plate below the second filter plate in sequence.

[0013] Optionally, the contact portion of the fixing pin with the outer frame is provided with external threads and is threadedly connected to the outer frame.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting the two filter plates to an inclined position, the inclined design further enhances the filtration effect. On the one hand, impurities can slide off naturally under the action of gravity, avoiding accumulation and clogging of the filter plate pores. This allows the filter plates to maintain a high effective filtration area and good pore permeability, allowing water to flow smoothly through for filtration. On the other hand, the inclined position promotes a more even distribution of water flow on the filter plates, ensuring that each area can fully exert its filtration function, thereby improving the overall filtration efficiency and ensuring a stable and efficient impurity interception effect.

[0016] 2. By incorporating an impact plate, the impact plate utilizes the vibration generated by the water flow. This vibration is transmitted to the filter plate, shaking off impurities adhering to the edges and surface of the filter plate pores, preventing clogging. During long-term continuous filtration, this design significantly reduces the occurrence of filter plate clogging due to impurity accumulation, allowing the filter plate to maintain good filtration performance for extended periods. This reduces the frequency of cleaning or replacing the filter plate, ensuring the continuity of the filter bed's filtration operation.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4As shown, this embodiment provides an integral cast filter plate for a filter bed, including: an outer frame 1, with two through slots 3 at the front end of the outer frame 1, and a first filter plate 5 and a second filter plate 7 respectively connected in the two through slots 3. Impact plates 6 are connected to the left and right sides of the surfaces of the first filter plate 5 and the second filter plate 7, and the first filter plate 5 and the second filter plate 7 are both inclined. Vibration mechanisms are connected to the left and right sides of the bottom ends of the first filter plate 5 and the second filter plate 7.

[0029] The outer frame 1 serves as the external support structure for the entire filter plate, fixing and protecting the internal components. Two through slots 3 are located at the front end, specifically designed for installing the first filter plate 5 and the second filter plate 7. The shape and size of the through slots 3 are adapted to the corresponding filter plates, allowing them to be accurately embedded. This ensures a stable connection while allowing water to flow smoothly through the through slots 3 into the filter plates for filtration. After the water flows through the surface of the outer frame 1 and into the two filter plates, impurities are trapped on the plates, while relatively clear water can pass through to continue the subsequent process, thus achieving preliminary filtration and purification. Both filter plates are inclined, and this inclination helps the trapped impurities slide naturally towards the lower end of the filter plates under gravity, preventing excessive accumulation of impurities. The filtration effect and water flow speed are similar to how a sloping surface makes it easier for an object to roll downhill; on the other hand, the inclined setting can also change the flow state of the water on the filter plate to a certain extent, so that the water flow can be more evenly distributed on the surface of the filter plate, improving the filtration efficiency and allowing each area of ​​the filter plate to fully perform its filtration function. When the water flows through the surface of the outer frame 1 and enters the filter plate, the water flow will impact the impact plate 6. The existence of the impact plate 6 can use the impact force of the water flow to generate a certain vibration effect, and this vibration can be transmitted to the filter plate itself, which helps to shake off the impurities attached to the filter plate and prevent them from clogging the pores of the filter plate, thereby maintaining the continuous, stable and efficient filtration capacity of the filter plate. The vibration mechanism is mainly intended to further enhance the vibration effect of the filter plate to better solve the problem of impurities clogging the filter plate during the filtration process.

[0030] In this embodiment, grooves are provided on both the left and right sides of the inner wall of the outer frame 1. These grooves are located below the first filter plate 5 and the second filter plate 7, respectively, and the vibration mechanism is located in the grooves. The grooves provide installation space for the vibration mechanism, allowing the vibration mechanism to be cleverly hidden within them. This avoids occupying extra space outside the filter plates and affecting the overall layout and installation of the filter plates in the filter tank. It also provides a certain degree of protection for the vibration mechanism, preventing it from being disturbed by external factors (such as water flow impact, filter media friction, etc.) and ensuring its stable operation.

[0031] The vibration mechanism includes a spring 9 fixedly connected to the bottom of the groove, and a support plate 8 fixedly connected to the top of the spring 9. The top of the support plate 8 abuts against the bottom of the first filter plate 5. When the water flow impacts the filter plate and the support plate 8 is subjected to a force in the vertical direction, the spring 9 will be compressed or stretched accordingly. Since the spring 9 has the characteristic of restoring its original shape, it will repeatedly extend and retract during the change of force, causing the support plate 8 connected to it to vibrate up and down. This vibration is then transmitted to the first filter plate 5 (and the second filter plate 7 with the same structure) that it abuts against, so that the filter plate produces a vibration effect, which helps to shake off the impurities adsorbed or accumulated on the filter plate, prevents pore blockage, and improves filtration efficiency.

[0032] The outer frame 1 is connected to the left and right side walls with fixing blocks 2. The surface of the fixing blocks 2 is provided with threaded holes. The fixing frame facilitates the connection between the outer frame 1 and other supporting structures in the filter tank. By screwing bolts and other connecting parts into the threaded holes, the filter plate can be accurately and firmly fixed in the predetermined position in the filter tank, ensuring that the filter plate will not shift during operation and maintaining the stability of the overall filtration structure of the filter tank.

[0033] A fixing pin 4 is connected to the top of the outer frame 1. The fixing pin 4 passes through the surface of the outer frame 1 and passes through the surface of the outer frame 1, the first filter plate 5, the support plate 8 below the first filter plate 5, the second filter plate 7, and the support plate 8 below the second filter plate 7 in sequence. The fixing pin 4 has external threads at the contact part with the outer frame 1 and is threadedly connected to the outer frame 1.

[0034] The through-type connection of the fixing pin 4 connects the outer frame 1, the two filter plates and the corresponding support plate 8 together to form a relatively tight overall structure, so that the relative positions of each component in the vertical direction can be fixed. At the same time, the fixing pin 4 and the two filter plates and the corresponding support plate 8 are all through-moving connections, allowing them to move up and down.

[0035] Working principle:

[0036] First, insert the two filter plates into the outer frame 1 along the through groove 3, and then fix them with pins. The fixing pin 4 is connected to the two filter plates and the corresponding support plate 8 through a movable connection. This ensures that the filter plates and support plate 8 will not be obstructed when they move up and down due to water flow impact, vibration mechanism action, etc., and ensures that the vibration mechanism can drive the filter plates to vibrate normally and that the filter plates themselves can slide down with impurities in the tilted state. At the same time, it maintains the integrity and stability of the whole structure, allowing the filter plates to continue to perform filtration work in a stable and reasonable structural state.

[0037] When water containing impurities flows towards the filter plates, suspended solids, particulate matter, and other impurities are trapped on the surface of the first filter plate 5 and the second filter plate 7 due to the filtration effect of the plates. The relatively clear water can then pass through the filter plates to continue the process. Both the first filter plate 5 and the second filter plate 7 are inclined. Impurities trapped on the filter plates will naturally slide down the inclined surface under the influence of gravity. This design simulates the principle of an object sliding down an inclined plane due to gravity, preventing impurities from accumulating excessively on the filter plates. Because if too many impurities accumulate, it will... Not only will it clog the pores of the filter plate, affecting the water flow speed, it will also reduce the effective filtration area of ​​the filter plate, thus affecting the overall filtration effect. Therefore, the inclined setting allows impurities to slide off in time, maintaining the filter plate's good filtration performance. At the same time, the inclined filter plate can also change the flow state of the water on its surface. When the water flows along the inclined surface, it will be more evenly distributed across the entire filter plate surface, allowing each area of ​​the filter plate to fully exert its filtration function and improve filtration efficiency, rather than having local water flow that is too fast and insufficient filtration, or local water flow that is too slow and serious impurity accumulation.

[0038] When water flows through the outer frame 1 into the filter plate, it impacts the impact plates 6 connected to the left and right sides of the surfaces of the first filter plate 5 and the second filter plate 7. The impact force of the water flow acts on the impact plates 6, causing them to vibrate. Since the impact plates 6 are connected to the filter plates, this vibration is transmitted to the filter plates themselves. At the same time, the spring 9 is compressed or stretched according to the force. Because the spring 9 has the characteristic of returning to its original shape, it will repeatedly extend and retract during the change of force, causing the support plate 8 connected to it to vibrate up and down, and then transmit this vibration to the filter plate, further enhancing the vibration effect of the filter plate. The vibration of the filter plate helps to shake off the impurities attached to the edges or surface of the filter plate pores, preventing them from clogging the pores of the filter plate.
