[0029] a support frame 100;

[0030] Cleaning assembly, the cleaning assembly includes a liquid storage tank 211, a water storage tank 212, a first cleaning tank 213 and a second cleaning tank 214; the liquid storage tank 211, the water storage tank 212, the first cleaning tank 213 and the second cleaning tank 214 are all arranged on the support frame 100; the liquid storage tank 211 stores cleaning liquid; several first flushing pipes 215 are arranged in the first cleaning tank 213, several second flushing pipes 216 are arranged in the second cleaning tank 214, and several water spraying nozzles 226 are arranged on the surfaces of the first flushing pipes 215 and the second flushing pipes 216 along the axial direction; one end of the first flushing pipe 215 is communicated with the liquid storage tank 211, and the second flushing pipe 216 is communicated with the water storage tank 212; two groups of ultrasonic transmitters are arranged on the inner wall surfaces of the two opposite sides of the first cleaning tank 213, and the two groups of ultrasonic generators 223 are arranged opposite to the first flushing pipe 215.

[0031] Specifically, the cleaning assembly in the present utility model is arranged on the support frame 100, wherein the first cleaning tank 213 and the second cleaning tank 214 are used for cleaning the stainless steel filter element 300. Specifically, the first cleaning tank 213 and the second cleaning tank 214 are respectively provided with a first flushing pipe 215 and a second flushing pipe 216. During the cleaning process, the stainless steel filter element 300 is sleeved outside the first flushing pipe 215 and the second flushing pipe 216, and backwashing is carried out from the inside of the stainless steel filter element 300. As a preferred solution of the present utility model, the first flushing pipe 215 is communicated with the liquid storage tank 211, and the liquid storage tank 211 is used for storing cleaning liquid (the medicine water used in the wet process). The multiple water spraying nozzles 226 on the surface of the first flushing pipe 215 flush the stainless steel filter element 300, dissolve the sediment attached to the surface of the stainless steel filter element 300 and then flush it away. Secondly, ultrasonic generators 223 are arranged in the first cleaning tank 213. Relying on the cleaning liquid as a medium, ultrasonic cleaning is carried out, and the sludge and sediment in each dead corner of the stainless steel filter element 300 can be cleaned. After the stainless steel filter element 300 in the first cleaning tank 213 is flushed, it is put into the second cleaning tank 214. The second flushing pipe 216 is communicated with the water storage tank 212. Similar to the first cleaning tank 213, the second flushing pipe 216 performs secondary water washing on the cleaned stainless steel filter element 300 to ensure that the stainless steel filter element 300 is completely cleaned.

[0032] The present utility model performs reverse flushing with medicine water and ultrasonic cleaning on the stainless steel filter element 300 through the first cleaning tank 213, and all the sediment and sludge attached to the stainless steel filter element 300 are cleaned. Secondly, the second cleaning tank 214 performs secondary water washing on the stainless steel filter element 300 to completely remove the medicine water and water stains inside and on the surface of the stainless steel filter element 300. The utility model can greatly clean the dirt attached to the surface of the filter element, greatly improve the filtering capacity of the filter element, extend the replacement cycle of the filter element at the same time, and effectively improve the quality.

[0033] Furthermore, a heating rod 219 is disposed inside the liquid storage tank 211. The heating rod 219 extends into the cleaning liquid, and a temperature sensor 220 is disposed on the liquid storage tank 211. The temperature sensor 220 is electrically connected to the heating rod 219.

[0034] Specifically, the heating rod 219 is disposed in the liquid storage tank 211 for heating the cleaning liquid in the liquid storage tank 211. The temperature of the cleaning liquid is detected by the temperature sensor 220. When the temperature reaches the set temperature, the heating rod 219 stops heating. After the heated cleaning liquid enters the first cleaning tank 213, the reaction rate of the precipitation is accelerated, the dissolution efficiency of the precipitation is improved, and thus it is ensured that the filter can be quickly rinsed clean.

[0035] Furthermore, plug heads 227 are disposed at the ends of the first flushing pipe 215 and the second flushing pipe 216, and a locking nut is disposed at one end of the plug head 227.

[0036] Specifically, the ends of the first flushing pipe 215 and the second flushing pipe 216 are blocked by the plug heads 227, so that the cleaning liquid and water are ejected from the water spraying ports 226. During actual operation, after the stainless steel filter element 300 is sleeved outside the first flushing pipe 215 and the second flushing pipe 216, the locking nut is then locked to ensure the stability of the stainless steel filter element 300 and prevent it from shaking during the flushing process.

[0037] Furthermore, a first spray pump 217 is disposed between the liquid storage tank 211 and the plurality of first flushing pipes 215. The first spray pump 217 provides power to pump out the cleaning liquid in the liquid storage tank 211 and spray it out from the first flushing pipe 215.

[0038] Furthermore, a second spray pump 218 is disposed between the water storage tank 212 and the plurality of second flushing pipes 216. Similarly, the function of the second spray pump 218 is to pump out the water in the water storage tank 212 and spray it out from the second flushing pipe 216.

[0039] Since the cleaning liquid contains corrosive substances, as a preferred embodiment of the present invention, the main components such as the first spray pump 217, the second spray pump 218, the temperature sensor 220, and the heating rod 219 are all made of corrosion-resistant materials.

[0040] Furthermore, a drain pipe 224 is disposed at the top of the first cleaning tank 213. The drain pipe 224 communicates with the liquid storage tank 211; and a first throttle valve 221 is disposed on the drain pipe 224. A drain pipe 225 is disposed at the top of the second cleaning tank 214. The drain pipe 225 communicates with the water storage tank 212; and a second throttle valve 222 is disposed on the drain pipe 225.

[0041] Specifically, in the present utility model, the cleaning liquid for rinsing the thickness is returned to the liquid storage tank again through the drain pipe 224, and returned to the water storage tank 212 through the drain pipe 225, so that the whole cleaning liquid and water form a cycle. As a preferred solution of the present utility model, filters can be added between the drain pipe 225 and the water storage tank 212 and between the drain pipe 224 and the liquid storage tank to filter the precipitated particles washed out, and extend the usage frequency of the cleaning liquid and water.

[0042] Furthermore, the lengths of the first flushing pipe 215 and the second flushing pipe 216 are equal to the length of the stainless steel filter element 300. During the flushing process, the whole filter element can be flushed to avoid the dead angle of repeated flushing.

[0045] In summary, the present utility model introduces a cleaning device and equipment for a stainless steel filter element. The present utility model uses the first cleaning tank 213 to perform reverse flushing and ultrasonic cleaning of the stainless steel filter element 300 with liquid medicine, and washes away all the precipitates and sludge attached to the stainless steel filter element 300. Secondly, the second cleaning tank 214 is used to perform secondary water washing on the stainless steel filter element 300 to completely remove the liquid medicine and water stains inside and on the surface of the stainless steel filter element 300. The utility model can clean the dirt attached to the surface of the filter element to a great extent, greatly improve the filtering capacity of the filter element, extend the replacement cycle of the filter element at the same time, and effectively improve the quality.
