Description

Technical Field

[0001] The utility model belongs to the field of biopharmaceutical wastewater treatment equipment, in particular to a wastewater inactivation tank. Background Art

[0002] A lot of live toxic wastewater is generated in the biopharmaceutical process, which contains a large number of viruses, bacteria and other biological toxins, or chemical toxins. It cannot be discharged directly and must be treated before being discharged. Therefore, it needs to be disinfected and sterilized before being transferred to the sewage treatment process. During disinfection and sterilization, an inactivation tank is used for operation, and the inner wall of the inactivation tank is prone to dirt and impurities, which will affect the subsequent inactivation and sterilization effect. Therefore, the inactivation tank needs to be cleaned. In the existing inactivation tank, a cleaning brush or a cleaning plate is set to clean the side wall, but the structure and function are relatively simple. For example, there are many impurities in the tank body that accumulate in clusters, which will cause drainage blockage. Therefore, there is an urgent need for an inactivation tank that can efficiently treat live toxic wastewater. Utility Model Content

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] As shown in the figure, a wastewater inactivation tank includes a tank body 1, and a connecting pipe 2 that is interconnected is vertically connected to the upper side of the tank body 1, a connecting plate 3 is fixedly connected to the upper opening of the connecting pipe 2, a filter frame 4 is provided at the bottom of the connecting plate 3 and is located in the connecting pipe 2 and is spaced between the circumferential outer wall and the inner wall of the connecting pipe 2, a water inlet 301 that is connected to the internal space of the filter frame 4 is provided on the upper side of the connecting plate 3, a water outlet 5 is provided at the bottom of one side wall of the tank body 1, and a cleaning mechanism is provided in the tank body 1. In this embodiment, the filter frame 4 is arranged in the connecting pipe 2, so that the wastewater is first filtered through the filter frame 4 and then enters the tank body 1, thereby reducing impurities in the tank body 1 and preventing the filter frame 4 from affecting the cleaning work of the cleaning mechanism on the inner wall of the tank body 1; at the same time, the circumferential outer wall of the filter frame 4 is spaced apart from the inner wall of the connecting pipe 2 to increase the filtering surface, that is, to increase the speed of the wastewater entering the tank body 1; and the connecting pipe 2 also serves as a manhole, saving the cost of processing a manhole on the tank body 1; when cleaning is required, the operator only needs to stand outside the connecting pipe 2, remove the connecting plate 3 and the filter frame 4, and then clean the inner wall of the connecting pipe 2, while the inner wall of the tank body 1 can be directly cleaned by the cleaning mechanism.

[0028] The upper surface of the tank body 1 is arranged as a horizontal structure, so that the operator can climb to the top of the tank body 1 through a ladder and stand on the horizontal surface of the top of the tank body 1 to operate the connecting plate 3 and the filter frame 4.

[0029] A connecting edge 302 is fixedly connected to the bottom of the connecting plate 3 along the outer side of the filter frame 4 in the circumferential direction, and two L-shaped slots 3021 are oppositely provided on the inner side wall of the connecting edge 302. A clamping block 401 is fixedly connected to the outer side of the upper edge of the filter frame 4 corresponding to the slot 3021, and the clamping block 401 is clamped into the horizontal section of the slot 3021 along the opening of the slot 3021 on the inner side wall of the connecting edge 302. In this embodiment, the filter frame 4 and the connecting plate 3 are set as a clamping structure, which is convenient for disassembly and replacement of the filter frame 4 later.

[0030] The bottom of the filter frame 4 is higher than the connection between the connecting pipe 2 and the tank body 1, or is flush with the connection between the connecting pipe 2 and the tank body 1. This arrangement can ensure that the filter frame 4 does not affect the cleaning operation of the cleaning mechanism on the inner wall of the tank body 1.

[0031] The cleaning mechanism includes a motor 6, a screw rod 7, a guide rod and a cleaning disk 8. The screw rod 7 and the guide rod are horizontally arranged between the left and right ends of the tank body 1. The motor 6 is fixed to the outside of the tank body 1, and the output shaft of the motor 6 is fixed to the screw rod 7. The cleaning disk 8 is screwed on the vertical screw rod 7 and is sleeved with the guide rod.

[0032] The shape of the cleaning disc 8 is consistent with the vertical cross-sectional shape of the inner wall of the tank body 1, and a scraper bar 801 with a triangular cross-section is fixedly connected to the outer walls around the cleaning disc 8. The scraper bar 801 contacts the inner wall of the tank body 1. When the motor 6 drives the screw rod 7 to rotate, the cleaning disc 8 moves horizontally along the screw rod 7, so that the scraper bar 801 scrapes and cleans the impurities attached to the inner wall of the tank body 1.

[0033] A flange 201 is fixedly connected to the outer side of the upper opening of the connecting pipe 2, and the connecting plate 3 is connected to the upper side of the connecting pipe 2 and is fixedly connected to the flange 201 through a plurality of bolt and nut pairs. In this embodiment, a sealing gasket is also provided at the contact surface between the connecting plate 3 and the connecting pipe 2 to play a sealing role.

[0034] A support block 9 is fixedly connected to the bottom of the tank body 1 .

[0035] The working process of this embodiment is as follows:

[0036] Wastewater enters the filter frame 4 from the water inlet 301 for preliminary filtration, and then enters the tank body 1 after filtration. When the inner wall of the tank body 1 needs to be cleaned, the motor 6 is started to drive the screw 7 to rotate, and the cleaning disk 8 moves horizontally along the screw 7, so that the scraper 801 scrapes and cleans the impurities attached to the inner wall of the tank body 1.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
