Description

Technical Field

[0001] The utility model relates to the field of direct drinking water disinfection equipment, in particular to a direct drinking water terminal disinfection device. Background Art

[0002] Direct drinking water is prone to breeding bacteria, algae, physical, chemical or biological secondary pollution during its long-term movement in the pipe. Existing equipment will install a filter frame inside the terminal water storage tank to filter out debris caused by pipe damage, but the installation and replacement of existing filter frames are relatively cumbersome.

[0003] According to the patent document with the existing publication number CN215924465U, a direct drinking water terminal disinfection device is disclosed, which includes a device body, a filter frame is installed inside the device body, a fixing rod is provided at one end of the top of the filter frame, a block is vertically provided at one end of the fixing rod, a fixing plate is provided on the inner wall surface of the device body, a slot is provided on the top surface of the fixing plate, a handle is provided at one end of the top of the filter frame, an inlet pipe is installed through the surface of the device body, and the end of the inlet pipe is located directly above the filter frame. When in use, this technical solution facilitates the removal and installation of the filter frame by coordinating the fixing rod, the block, the fixing plate, the slot and the handle. When the filter frame needs to be removed for maintenance, the staff grasps the pull rod through the inspection port, then lifts it upward, and then disengages the block from the slot, and then removes the filter frame from the inspection port. With respect to the above technical solution, although this solution realizes the rapid removal of the filter frame, the disinfection lamp can only complete the disinfection and sterilization of the top water surface when water is inflowing, and cannot quickly and comprehensively disinfect the water inside the water tank, which is inconvenient during use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a terminal disinfection device for direct drinking water to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. When in use, a circulation pump extracts and circulates the water inside the water tank. During the circulation, ozone enters the water and is sprayed upward through the nozzle. After the nozzle sprays water, the water inside the water tank rolls. During the rolling, the water is fully disinfected again through disinfection to avoid the generation of disinfection dead corners. In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a terminal disinfection device for direct drinking water, comprising a base, a water tank is fixed on the base, a circulation box is fixed between the water tank and the base, a disinfection box is fixedly installed between the circulation box and the water tank, a pipe is fixed on the side of the water tank, a water inlet pipe and a sewage pipe are fixedly installed on the pipe, a motor box is fixed on the top of the water tank, and a water outlet pipe is fixed on the side of the motor box.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a direct drinking water terminal disinfection device, comprising a base 1, a water tank 2 is fixed on the base 1, a circulation box 3 is fixed between the water tank 2 and the base 1, a disinfection box 4 is fixedly installed between the circulation box 3 and the water tank 2, a pipe 5 is fixed on the side of the water tank 2, a water inlet pipe 6 and a sewage pipe 7 are fixedly installed on the pipe 5, a motor box 10 is fixed on the top of the water tank 2, a water outlet pipe 11 is fixed on the side of the motor box 10, a ventilation pipe 8 is fixed on the top of the water tank 2, a ventilation hole 9 is opened on the ventilation pipe 8, a filter assembly 14 is fixed on the inner wall of the ventilation hole 9, and the filter assembly 14 is a filter plate. The filter plate prevents external bacteria from entering the interior of the water tank 2 and realizes the ventilation use of the interior of the water tank 2.

[0022] In this embodiment, a fixed block 12 is fixed to the top of the inner wall of the water tank 2, and a disinfection lamp 13 is fixedly installed between the fixed blocks 12. A water pump 15 is fixedly installed inside the motor box 10, and an extraction pipe 16 is fixed on the water pump 15. The extraction pipe 16 is installed inside the water tank 2, and one end of the outlet pipe 11 is installed on the water pump 15. An ozone generator 23 is fixedly installed inside the disinfection box 4, and a circulating pump 25 is fixedly installed inside the circulation box 3. A fixed pipe 26 is installed between the circulating pump 25 and the water tank 2, and the fixed pipe 26 is connected to the ozone generator 23. A one-way valve 24 is fixedly installed between the generators 23. The ozone generator 23 is an existing mature equipment and can be used directly inside the device. Ozone is a strong oxidant with a broad-spectrum and highly efficient bactericidal effect. Its bactericidal speed is 600 to 3000 times faster than chlorine. It is mainly used for disinfection of drinking water, air disinfection and food preservation. Generally, 0.5 to 1.5 mg / L of ozone is added for 5 minutes, and the residual ozone concentration in the water should be maintained at 0.1 to 0.5 mg / L. For severely polluted water, the amount of ozone added should be 3 to 6 mg / L, which can be directly used for drinking water disinfection.

[0023] In this embodiment, a support pipe 22 is fixed on the circulation pump 25, a connecting pipe 19 is fixed on one end of the support pipe 22, a cross pipe 20 is fixedly installed on the connecting pipe 19, a nozzle 21 is fixedly installed on the cross pipe 20, a filter cover 27 is fixed on one end of the water inlet pipe 6, one end of the sewage pipe 7 is installed on the filter cover 27, a control valve 28 is fixedly installed on one end of the pipe 5, a partition plate 17 is fixed inside the water tank 2, an opening 18 is opened on the partition plate 17, and the filter cover 27 filters the water entering the water inlet pipe 6 to prevent larger impurities from entering the interior of the water tank 2.

[0024] When the device is in use, the water inlet pipe 6 is connected to the external water supply pipe. The water supply pipe injects water into the water tank 2 through the water inlet pipe 6. Before the water inlet pipe 6 enters the water tank 2, the impurities in the water are filtered through the filter cover 27. The filtered water enters the water tank 2 through the control valve 28. After the water enters the water tank 2, the circulation pump 25 is started to circulate the water in the water tank 2. When the water enters the circulation pump 25 through the fixed pipe 26, a small amount of ozone generated by the ozone generator 23 enters the ozone generator through the one-way valve 24. The ozone enters the support pipe 22 along with the water. The ozone inside the support pipe 22 After the water enters the interior of the connecting pipe 19, it flows to the horizontal pipe 20 respectively, and is sprayed upward through the nozzle 21 on the horizontal pipe 20. The water rolls upward, and the rolling water realizes the up and down flow of the internal water. When rolling up and down, it is disinfected again through the disinfection lamp 13, and the water pump 15 is started to discharge the disinfected water through the outlet pipe 11. When the water has been inhaled for a long time, the filter cover 27 needs to be cleaned regularly. When cleaning, the control valve 28 is closed to stop the water inlet. The water entering the water inlet pipe 6 flushes the filter cover 27, and the impurities on the surface are flushed off and discharged from the sewage pipe 7 for cleaning, so as to facilitate reuse in the future.
