Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device for a multi-chamber cleaning machine. Background Art

[0002] A multi-chamber cleaning machine refers to an automatic cleaning device with multiple independent cleaning areas or functional areas. In a medical environment, multi-chamber cleaning machines are particularly important because they can help ensure that medical devices and equipment are thoroughly cleaned, thereby reducing the risk of hospital-acquired infections. After the multi-chamber cleaning machine is used, sewage will be generated. Generally, the sewage needs to be treated before it can be discharged to avoid environmental pollution.

[0003] Currently, when treating the sewage discharged from a multi-chamber cleaning machine, generally, the sewage is first filtered, then chemically and biologically treated, and finally, operations such as activated carbon adsorption are carried out. In actual use, solid substances will gradually adhere to the filter plate or filter mesh during filtration. After a long time, the gaps in the filter plate or filter mesh will shrink, which will affect the filtration effect. Summary of the Utility Model

[0031] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the drawings.

[0032] Figure 1 This is a schematic structural diagram of the present utility model, and in combination with Figure 2 As shown, the sewage treatment device of this multi-compartment cleaning machine includes a treatment tank 1, the top of which is provided with a top cover 9. A sewage inlet pipe 10 is connected on the top cover 9 and at the outlet of the filtration chamber 2. A drain pipe 11 is connected to the treatment tank 1 and at the end of the adsorption chamber 4. The inside of the treatment tank 1 is divided into a filtration chamber 2, a treatment chamber 3 and an adsorption chamber 4 in sequence by a partition board according to the treatment sequence. A filter screen 5 is installed in the filtration chamber 2, a biological treatment layer 6 is provided in the treatment chamber 3, and an activated carbon adsorption layer 12 is provided in the adsorption chamber 4. The biological treatment layer 6 uses microorganisms (such as bacteria, algae and other microorganisms) to decompose and transform organic pollutants in the sewage. In addition, a chemical treatment chamber can be set up during the treatment process as needed to use chemical reagents to neutralize or remove harmful substances. It also includes a purging component 7 and a reciprocating motion component 8. The purging component 7 includes a vertical purging pipe 71. The purging pipe 71 is located in the treatment chamber 3 and is close to the filter screen 5. A plurality of vertical air outlet nozzles 73 are equidistantly installed on the purging pipe 71. A wiping pad 74 is fixed between the upper and lower air outlet nozzles 73. The protruding length of the air outlet nozzle 73 does not exceed the protruding length of the wiping pad 74. The reciprocating motion component 8 is used to drive the purging pipe 71 to reciprocate along the back of the filter screen 5, so as to use the air outlet nozzle 73 to backflush the filter screen 5 to blow off the solids adhered to the front of the filter screen 5, and use the wiping pad 74 to reciprocally wipe the back of the filter screen 5 to improve the permeability.

[0033] Among them, in the specific implementation of the present utility model, referring to Figure 1 and Figure 3 as shown, the reciprocating motion assembly 8 includes:

[0034] A connecting seat 84, which is installed at the top end of the purging pipe 71;

[0035] A rack 83, one end of the rack 83 is fixed to the connecting seat 84, and the other end of the rack 83 extends outside the top cover 9;

[0036] A servo motor 81, which is installed outside the processing box 1. The servo motor 81 is a motor whose shaft can rotate forward and backward, and a gear 82 is installed at the output end of the servo motor 81. The gear 82 is meshed with the rack 83.

[0037] In addition, referring to Figure 3 and Figure 4 as shown, a convex strip 85 is fixed to the top end of the wire frame of the filter net 5. A guide groove 87 is formed in the convex strip 85 along the length direction. A guide block 86 that is slidably matched with the guide groove 87 is fixed to the surface of the connecting seat 84 facing the convex strip 85.

[0038] Referring to Figure 1 and Figure 2 as shown, the top end of the purging pipe 71 is connected with a blowing air hose 72. The blowing air hose 72 penetrates through the connecting seat 84 and also penetrates through the top cover 9.

[0039] Through the above technical solutions: during specific use, the sewage after cleaning the multi-compartment cleaning machine to be processed can be sent to the sewage inlet pipe 10 through a pipeline. The sewage first enters the filtering chamber 2 and is processed through the filter net 5, and then passes through the processing chamber 3 and the adsorption chamber 4 for processing again. The processed water is discharged from the drain pipe 11.

[0040] Among them, after using for a period of time, when the filtering effect of the filter net 5 becomes poor, at this time, air can be introduced through the blowing air hose 72. The air is blown to the back of the filter net 5 through the plurality of air outlets 73 on the purging pipe 71, and the servo motor 81 can be started. By using the forward and reverse alternating operation of the output end of the servo motor 81, the gear 82 can be driven to rotate, and then the reciprocating extension and retraction of the rack 83 meshed with the gear 82 can be driven. Thus, the back of the filter net 5 can be reciprocally purged by the purging pipe 71 to blow off the solids on the front of the filter net 5. And at the same time, the plurality of wiping pads 74 can move synchronously to wipe the back of the filter net 5. The synchronous processing of the front and the back can quickly clean it, thereby ensuring the filtering effect and without manual brushing, which is more convenient and labor-saving.

[0041] In addition, when the rack 83 extends or retracts, the guide block 86 slides linearly along the guide groove 87, which can ensure the stability of the movement of the rack 83 and the purging pipe 71.

[0042] In addition, when purging is not required, the reciprocating motion assembly 8 is used to move the purge pipe 71 to one side for storage, so as to reduce obstruction.

[0043] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
