[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The utility model discloses a capacity expansion drainer, such as Figure 1 As shown, it includes a tank body 1, and a drainage pipe 2 is fixedly installed on the outer bottom surface of the tank body 1, so that the treated waste water can be discharged.

[0024] A sewage pipe 3 is fixedly installed on one side of the outer surface of the tank body 1, and sewage can enter the tank body 1 through the sewage pipe 3. A filter box 4 is fixedly installed on the outer surface of the sewage pipe 3. When sewage enters the sewage pipe 3, it will enter the filter box 4.

[0025] A water inlet pipe 5 is fixedly installed on one side of the outer bottom surface of the tank body 1 to facilitate the transmission of cooling water to the heat exchanger 101 through the water inlet pipe 5, and a water outlet pipe 6 is fixedly installed on the other side of the outer bottom surface of the tank body 1 to facilitate the discharge of cooling water.

[0026] A steam pipe 7 is fixedly mounted on the outer top surface of the tank body 1 , and steam can be discharged through the steam pipe 7 .

[0027] like Figure 2 As shown, a heat exchanger 101 is fixedly installed inside the tank body 1 , one end of the heat exchanger 101 is fixedly connected to the water inlet pipe 5 , and the other end of the heat exchanger 101 is fixedly connected to the water outlet pipe 6 .

[0028] Two support rods 102 are fixedly installed inside the tank body 1, and one end of the two support rods 102 is fixedly connected to a steam-water separator 103. When hot sewage enters the tank body 1, the steam-water separator 103 can separate it into secondary steam and discharge it from the steam pipe 7, while the hot wastewater will be inside the tank body 1.

[0029] A slide bar 104 is fixedly mounted on the outer top surface of the tank body 1 , and a rack 105 is movably connected to the outer surface of the slide bar 104 , and the rack 105 can be raised and lowered along the slide bar 104 .

[0030] A first spring 106 is fixedly mounted on the outer surface of the slide bar 104 , and the first spring 106 is fixedly connected to the rack 105 . When the rack 105 rises, it can compress the first spring 106 .

[0031] Fixed rods 107 are fixedly installed on both sides of the rack 105. When the rack 105 is raised or lowered, the two fixed rods 107 can be driven to be raised or lowered.

[0032] A connecting rod 108 is fixedly mounted on one side of the two fixing rods 107 , and a cleaning plate 109 is disposed on one end of the two connecting rods 108 away from the fixing rod 107 . When the rack 105 is raised or lowered, the cleaning plate 109 can be raised or lowered.

[0033] A first motor 111 is fixedly mounted on one side of the outer top surface of the tank body 1 , and a gear 110 is fixedly mounted on the output end of the first motor 111 . The first motor 111 can drive the gear 110 to rotate.

[0034] It should be noted that one side of the gear 110 is provided with teeth. When the first motor 111 drives the gear 110 to rotate, when the side of the gear 110 provided with teeth is engaged with the rack 105, the rack 105 can be pushed to rise to squeeze the first spring 106. As the rack 105 rises, the cleaning plate 109 can be raised. When the side of the gear 110 provided with teeth is not engaged with the rack 105, under the action of the first spring 106, the rack 105 can be pushed to descend, so that the cleaning plate 109 can be lowered. As the gear 110 continues to rotate, the rack 105 can be repeatedly raised and lowered, so that the cleaning plate 109 can clean the dirt on the inner wall.

[0035] like Figure 3 As shown, the cleaning plate 109 includes a mounting sleeve 1091 and a mounting block 1092 , and the connecting rod 108 is fixedly connected to the mounting sleeve 1091 .

[0036] A mounting groove 1096 is provided on the bottom surface of the mounting sleeve 1091, mounting holes 1093 are provided on both sides of the mounting groove 1096, a connecting hole 1094 is provided on one side of the mounting block 1092, bristles 1095 are fixedly installed on one side of the mounting block 1092, and the size of the connecting hole 1094 is the same as that of the mounting hole 1093. When the mounting block 1092 is inserted into the mounting groove 1096, the connecting hole 1094 will coincide with the mounting hole 1093, and then, the bolts are inserted to connect the mounting sleeve 1091 to the mounting block 1092.

[0037] like Figure 4 As shown, the filter box 4 is movably connected to a filter plate 401 inside. When sewage enters the filter box 4, the filter plate 401 can filter the impurities therein, so as to effectively prevent the impurities in the sewage from clogging the drain pipe 2 when the sewage is discharged.

[0038] Hanging rings 402 are movably installed on both sides of the outer surface of the filter box 4, and extension sleeves 403 are fixedly installed on both sides of the filter plate 401. Second springs 404 are fixedly installed inside the two extension sleeves 403, and movable rods 406 are fixedly installed at one end of the two second springs 404. Hooks 405 are fixedly installed at one end of the two movable rods 406 away from the second springs 404. When the filter plate 401 is inserted into the filter box 4, the hooks 405 are hung in the hanging rings 402 to prevent the filter plate 401 from falling during filtering.

[0039] like Figure 5 As shown, a spiral transmission rod 202 is movably installed inside the drain pipe 2, a second motor 201 is fixedly installed on one side of the outer surface of the drain pipe 2, and the output end of the second motor 201 is fixedly connected to the spiral transmission rod 202. The second motor 201 can drive the threaded transmission rod to rotate, and a drain outlet 203 is provided on one side of the outer surface of the drain pipe 2.

[0040] The working principle of the utility model is as follows: hot sewage will enter the tank body 1 through the sewage pipe 3. When the hot sewage enters the filter box 4, the filter plate 401 can filter it to effectively prevent its internal impurities from entering the tank body 1. When the hot sewage enters the tank body 1, the steam-water separator 103 can separate it into secondary steam and discharge it from the steam pipe 7, and the hot waste water will be inside the tank body 1. Then, the cooling water is transmitted to the heat exchanger 101 through the water inlet pipe 5, and the cooling water can be discharged through the outlet pipe 6. When the temperature of the hot sewage drops, the valve 204 can be opened to discharge it from the drain pipe 2, and then the first motor 111 can be started, and the first motor 111 drives the The movable gear 110 rotates, and when the side of the gear 110 with teeth is meshed with the rack 105, the rack 105 can be pushed to rise, and then the rack 105 will squeeze the first spring 106. As the rack 105 rises, the cleaning plate 109 can be raised. When the gear 110 continues to rotate, when the side with teeth is not meshed with the rack 105, under the action of the first spring 106, the rack 105 can be pushed to descend, and then the cleaning plate 109 can be descended. As the gear 110 continues to rotate, the rack 105 can be reciprocated, so that the cleaning plate can reciprocate up and down, which is convenient for cleaning the dirt attached to the inner wall.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
