[0001] The utility model relates to the technical field of filters, in particular to a high-speed filter for preventing the filter screen plate from deforming. Background Art

[0002] The high-speed filter is one of the main devices for modern industrial water treatment. The high-speed filter is very suitable for purifying the turbid water of rolling mills and continuous casting in steel enterprises, as well as side filtration treatment in the circulating system.

[0003] The patent with the publication number CN211513556U discloses a high-speed filter. The filter plate is provided to support the filter material. By arranging a water distribution structure at the upper part of the cylinder body and filter material at the lower part, the sewage is evenly injected into the filter material, improving the utilization area of the filter material and thus enhancing the filtering effect. However, during the use of this high-speed filter, due to the too large area of the filter plate, the gravity of the filter material plus the raw water and the reciprocating impact force on the filter plate during backwashing are likely to cause the filter plate to deform. The deformation of the filter plate causes the filter material to escape from the gap, affecting the filtering effect. Therefore, it can no longer meet the needs of modern people. In view of these defects, it is very necessary to design a high-speed filter for preventing the filter screen plate from deforming. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-speed filter for preventing the filter screen plate from deforming. The high-speed filter for preventing the filter screen plate from deforming can avoid the deformation of the filter screen caused by the gravity of the filter material plus the raw water, which may cause the filter screen to crack over time and affect the filtering effect. By installing the fixing plate on the filter material component through the fixing piece, it can avoid the deviation of the filter screen when it is impacted, and further prevent the filter material in the filter material layer from leaking out, resulting in waste of the filter material and affecting the filtering effect. It can solve the problems in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a high-speed filter for preventing the filter screen plate from deforming, including a high-speed filter body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] After the up-and-down impact force received by the filter net disappears due to the support component provided by the present utility model, the spring loses the extrusion force and restores the elastic force, causing the slider to move downward, driving the connection component to reset, and restoring the filter net, avoiding the deformation of the filter net caused by the gravity of the filter media and raw water. Over time, the filter net may crack, affecting the filtering effect. By installing the fixing plate on the filter media component through the fixing pieces, it can be avoided that the filter net shifts when receiving the impact force, and then the filter media in the filter media layer leaks out, resulting in waste of filter media and affecting the filtering effect.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] In order to solve the technical problem that in the process of using the existing high-speed filter, due to the too large area of the filter plate, the gravity of the filter media and raw water, and the reciprocating impact force on the upper and lower sides of the filter plate during backwashing, it is easy to cause the filter plate to deform, and the deformation of the filter plate causes the filter media to run off from the gap, affecting the filtering effect, please refer to Figures 1 - 6 This embodiment provides the following technical solutions:

[0023] A high-speed filter for preventing the deformation of the filter net plate, including a high-speed filter body 1. An inlet pipe 8 is provided at the top of the high-speed filter body 1. The inlet pipe 8 passes through the top of the high-speed filter body 1 and is communicated with a water distribution plate 2. A plurality of nozzles are provided at the bottom of the water distribution plate 2. A support assembly 3 is installed on the inner wall of the high-speed filter body 1.

[0024] In this embodiment, the support assembly 3 includes a fixed column 31, a sliding groove 32, a connection assembly 33, a pressing piece 34, a first buckle 35, a sliding rod 36, a spring 37, a slider 38 and a second buckle 39. A sliding groove 32 is formed in the fixed column 31, a sliding rod 36 is installed in the sliding groove 32, a slider 38 is movably installed at the bottom of the sliding rod 36, a second buckle 39 is fixed to the outer side of the slider 38, a connection assembly 33 is installed on the second buckle 39, the other end of the connection assembly 33 is installed on the first buckle 35, the first buckle 35 is fixed to the pressing piece 34, the pressing piece 34 is fixed to the filter net 44. The connection assembly 33 includes a connecting rod 331, a first hook 332 and a second hook 333. A first hook 332 is provided at one end of the connecting rod 331, and a second hook 333 is provided at the other end. The first hook 332 is installed on the first buckle 35, and the second hook 333 is installed on the second buckle 39. When the filtering assembly 4 is subjected to an up-and-down reciprocating impact force, the filter net 44 arches upward, the connection assembly 33 moves upward along the sliding rod 36 under the impact of the impact force, the slider 38 moves upward to compress the spring 37. After the up-and-down impact force disappears, the spring 37 loses the extrusion, so that the slider 38 moves downward, and the connection assembly 33 resets, so that the filter net 44 is restored, avoiding the deformation of the filter net 44 caused by the gravity of the filter material plus the raw water. Over time, the filter net 44 cracks, affecting the filtering effect.

[0025] In this embodiment, the filtering assembly 4 includes a fixing plate 41, a reinforcing rib 42 and a filter net 44. The filter net 44 is installed inside the fixing plate 41, and the reinforcing rib 42 is fixed to the filter net 44. The provided reinforcing rib 42 can increase the strength of the filter net 44 and avoid the deformation of the filter net 44 under impact. The fixing plate 41 is installed on the filter material assembly 5 through a fixing member 45, which can prevent the filter net 44 from shifting when subjected to an impact force, and then causing the filter material in the filter material layer 55 to leak out, resulting in waste of the filter material and affecting the filtering effect. An installation hole 43 is formed in the upper surface of the fixing plate 41, and a fixing member 45 is installed in the installation hole 43. The fixing plate 41 is fixed to the filter material assembly 5 through the fixing member 45 passing through the installation hole 43.

[0026] In this embodiment, the filter media assembly 5 includes a cylinder 51, a stirring assembly 52, a cover plate 53, a support plate 54 and a filter media layer 55. A support plate 54 is fixed to the bottom of the cylinder 51. A cover plate 53 is provided above the cylinder 51. A filter media layer 55 is provided between the cover plate 53 and the support plate 54. A stirring assembly 52 is provided in the filter media layer 55. A fixing hole 57 is provided on the upper surface of the cylinder 51. A plurality of mesh holes 56 are provided on both the cover plate 53 and the support plate 54. The filter media layer 55 is composed of quartz sand filter media and pebble filter media. The stirring assembly 52 includes a motor, a stirring shaft and stirring rods. The output end of the motor is equipped with a stirring shaft. A number of stirring rods are equidistantly installed on the stirring shaft. Start the motor to make the stirring shaft rotate and drive the stirring rods to stir, stirring the filter media in the filter media layer 55, so that the filter media can be cleaned more thoroughly and the filtering effect of the filter media layer 55 is ensured.

[0027] Working principle: When in use, sewage enters the high-speed filter body 1 from the water inlet 10 under the action of a water inlet pump. Under a certain pressure and intensity, it sequentially passes through the filter media assembly 5 and the filter screen 44 and is discharged through the water outlet 9. Then, close the water inlet 10, connect the water inlet pipe 8 to receive water, and the water sprays out from the nozzles through the water distribution plate 2 to wash the dirt on the filter screen 44 and the filter media layer 55. When the filter screen 44 is subjected to an up-and-down reciprocating impact force, the filter screen 44 arches upward. The connecting assembly 33 moves upward along the slide rod 36 under the impact of the impact force. The slider 38 moves upward to compress the spring 37. After the upward impact force disappears, the spring 37 loses the compression, causing the slider 38 to move downward and the connecting assembly 33 to reset, so that the filter screen 44 returns to its original state. Start the motor during the flushing process to make the stirring shaft rotate and drive the stirring rods to stir, stirring the filter media in the filter media layer 55. The flushing sewage is discharged through the water outlet pipe 7.

[0028] In summary, for this high-speed filter that prevents the filter screen plate from deforming, through the provided support assembly 3, when the filter screen 44 is subjected to an up-and-down reciprocating impact force, the filter screen 44 arches upward. After the up-and-down impact force disappears, the spring 37 loses the compression, causing the slider 38 to move downward and the connecting assembly 33 to reset, so that the filter screen 44 returns to its original state, avoiding the deformation of the filter screen 44 caused by the gravity of the filter media plus the raw water, which may cause the filter screen 44 to crack over time and affect the filtering effect. By installing the fixing plate 41 on the filter media assembly 5 through the fixing member 45, it can be avoided that the filter screen 44 shifts when subjected to an impact force, thereby causing the filter media in the filter media layer 55 to leak out, resulting in waste of filter media and affecting the filtering effect at the same time. By stirring the filter media in the filter media layer 55 through the stirring assembly 52, the filter media can be cleaned more thoroughly and the filtering effect of the filter media layer 55 is ensured.
