Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment chlorine dioxide disinfection machine. Background Technology
[0002] A chlorine dioxide disinfection machine, also known as a chlorine dioxide generator, is a device that produces chlorine dioxide on-site. It generates chlorine dioxide by reacting sodium chlorate, sodium chlorite, or a mixture of the two with hydrochloric acid. In wastewater treatment, it has functions of sterilization, disinfection, deodorization, and decolorization. It not only ensures the safe discharge of wastewater but also improves the overall quality of water, providing strong support for environmental protection and resource recycling.
[0003] In existing chlorine dioxide disinfection machines, when used in cold weather or during seasons with low temperatures, the raw material liquid medium inside the equipment may freeze or condense when the temperature is below 5℃. Especially during shutdown, the internal temperature of the equipment will gradually decrease. If no effective insulation measures are taken, the medium is more likely to freeze, leading to pipe blockage, valve malfunction, and other faults, affecting the normal operation of the equipment. Utility Model Content
[0004] The purpose of this invention is to provide a chlorine dioxide disinfection machine for wastewater treatment. It uses a dual-head temperature sensor to monitor the temperature inside and outside the dual-chamber regulating column. The control module controls the opening and closing of the heating tube via sensor signals, enabling the water inside the dual-chamber regulating column to be heated according to the external ambient temperature. Once the water temperature reaches a preset value, the heating tube circuit is shut off. This keeps the raw materials inside the raw material tank warm, preventing them from freezing due to low temperatures and maintaining the normal operation of the equipment. Furthermore, the dual-chamber regulating column can be slid out of the raw material tank for easy replacement if the tank is damaged.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0023] like Figures 1-3 As shown, a chlorine dioxide disinfection machine for wastewater treatment includes raw material tanks 102 symmetrically and fixedly assembled on both sides of a chlorine dioxide disinfection machine 1. The raw material tanks 102 are fixedly connected to the chlorine dioxide disinfection machine 1 via a base 101 at the bottom. A double-cavity adjusting column 103 is movably sleeved on the outer wall of the raw material tanks 102. A cover 108 is fixedly connected to the bottom of the double-cavity adjusting column 103. The double-cavity adjusting column 103 is configured as a hollow annular column. A heating tube 106 is symmetrically and fixedly connected to the top of the cover 108 and inside the double-cavity adjusting column 103. A heat dissipation pipe 107 is symmetrically fixedly connected to the middle of the 6. A control module 104 for controlling the opening and closing of the heating pipe 106 is electrically connected to one side of the cover 108. The control module 104 includes a microcontroller and a relay. A dual-head temperature sensor 121 for monitoring the internal and external temperatures of the dual-cavity regulating column 103 is fixedly assembled on the top of the dual-cavity regulating column 103. The dual-head temperature sensor 121 is electrically connected to the control module 104. A water inlet 119 is opened on the top of the dual-cavity regulating column 103, and a drain outlet 120 is opened on one side of the bottom of the dual-cavity regulating column 103.
[0024] According to the above structure, water is injected into the dual-cavity regulating column 103 through the water inlet 119, and the drain outlet 120 is used for periodic drainage. The external probe of the dual-head temperature sensor 121 monitors the external ambient temperature and transmits the sensing signal to the microcontroller of the control module 104. The microcontroller determines whether to turn the heating tube 106 on or off based on the preset temperature threshold and control algorithm. When the water temperature is lower than the set value, the dual-head temperature sensor 121 monitors the temperature through its internal probe located in the dual-cavity regulating column 103 and transmits the sensing signal to the microcontroller. The microcontroller closes the circuit of the heating tube 106 through a relay to start heating the water in the dual-cavity regulating column 103. When the set water temperature is reached, the microcontroller then controls the circuit of the heating tube 106 to open and stop heating. The heat dissipation pipes 107 are distributed inside the dual-cavity regulating column 103 to evenly distribute heat and accelerate the rise of water temperature. The dual-cavity regulating column 103 wraps around the outside of the raw material tank 102 to maintain the temperature of the raw material tank 102, reduce heat loss, and play a role in heat preservation.
[0025] Reference Appendix Figures 2-6The control module 104 is electrically connected to the chlorine dioxide sterilizer 1 via a plug 105 on one side. A protruding plate 123 is fixedly connected to the inner side of the dual-cavity adjusting column 103. A limiting groove 122 for movably engaging with the protruding plate 123 is provided on one side of the raw material tank 102. Several inner pipes 109 are fixedly connected to the side wall of the raw material tank 102 extending inward. A sealing groove 110 is provided on the outer wall of the raw material tank 102 at one end of the inner pipe 109. Several outer pipes 111 are fixedly connected to the outer wall of the dual-cavity adjusting column 103 extending outward. A sealing groove 112 is provided at one end of the outer pipe 111. A connecting pipe 113 is movably engaged with the inner wall of the outer pipe 111. A sealing groove 112 is movably sleeved on the outer wall of the connecting pipe 113 for engaging with the sealing groove. The sealing ring 116 is fitted into the groove 112. One end of the connecting pipe 113 is fixedly connected to the screw pipe 114. The side wall of the double-cavity adjusting column 103 is provided with a through hole for the screw pipe 114 to pass through. The screw pipe 114 is threadedly connected to the inner pipe 109. One end of the outer wall of the screw pipe 114 is movably fitted with a sealing ring 115 for movably fitting with the sealing groove 110. A liquid level pipe 117 is provided on the outside of the double-cavity adjusting column 103. The two ends of the liquid level pipe 117 are rotatably connected to the two connecting pipes 113 respectively. A pump suction pipe 118 is provided on one side of the double-cavity adjusting column 103. One end of the pump suction pipe 118 is rotatably connected to one of the connecting pipes 113. The other end of the pump suction pipe 118 is fixedly connected to the chlorine dioxide disinfection machine 1.
[0026] According to the above structure, when the raw material tank 102 is damaged after long-term use and needs to be replaced, first unplug the plug 105 and drain the water inside the double-chamber regulating column 103 through the drain port 120. Then, rotate the connecting pipes 113 at both ends of the liquid level pipe 117 to separate the screw pipe 114 from the inner pipe 109, thereby removing the liquid level pipe 117. In the same way, remove the connecting pipe 113 at one end of the pump suction pipe 118. Then slide it upwards to remove the double-chamber regulating column 103 along with the cover 108 from the outer wall of the raw material tank 102. The engagement of the sealing ring 115 with the sealing groove 110 and the engagement of the sealing ring 116 with the sealing groove 112 can maintain the sealing performance of the connecting pipe 113 when screwed with the inner pipe 109, preventing the leakage of raw materials or water. The limiting groove 122 and the protrusion 123... The sliding fit ensures that when the dual-cavity regulating column 103 is connected to the raw material tank 102, the center of the outer pipe 111 can be aligned with the center of the inner pipe 109, facilitating the screw connection of the connecting pipe 113. This invention monitors the internal and external temperatures of the dual-cavity regulating column 103 using a dual-head temperature sensor 121. The control module 104 controls the opening and closing of the heating tube 106 through sensor signals, thereby heating the water inside the dual-cavity regulating column 103 according to the external environment and controlling the circuit of the heating tube 106 to shut off after the water temperature reaches the preset value. This can keep the raw materials inside the raw material tank 102 warm, preventing them from freezing due to low temperatures and maintaining the normal operation of the equipment. It can also slide the dual-cavity regulating column 103 off the raw material tank 102 for easy replacement if the raw material tank 102 is damaged.
[0027] The working principle of this utility model is as follows: water is injected into the dual-cavity regulating column 103 through the water inlet 119, and the drain outlet 120 is used for periodic drainage. The external probe of the dual-head temperature sensor 121 monitors the external ambient temperature and transmits the sensing signal to the microcontroller of the control module 104. The microcontroller determines whether to turn the heating tube 106 on or off according to the preset temperature threshold and control algorithm. When the water temperature is lower than the set value, the dual-head temperature sensor 121 monitors the temperature through its internal probe located inside the dual-cavity regulating column 103 and sends the sensing signal to the microcontroller. The microcontroller then closes the circuit of the heating tube 106 via a relay, starting to heat the water inside the dual-cavity regulating column 103. When the set water temperature is reached, the microcontroller then controls the heating tube 106 circuit to open, stopping the heating. The heat dissipation pipes 107 distributed inside the dual-cavity regulating column 103 can evenly distribute heat and accelerate the rise in water temperature. The dual-cavity regulating column 103 surrounds the raw material tank 102, maintaining the temperature of the raw material tank 102, reducing heat loss, and playing a role in heat preservation. When the raw material tank 102 is damaged after long-term use and needs to be replaced, first unplug the plug 105 and drain the contents of the dual-cavity regulating column 103 through the drain port 120. Water, then rotate the connecting pipes 113 at both ends of the level pipe 117 to separate the screw pipe 114 from the inner pipe 109, thereby removing the level pipe 117. In the same way, remove the connecting pipe 113 at one end of the pump suction pipe 118. Then slide it upwards to remove the double-chamber adjusting column 103 along with the cover 108 from the outer wall of the raw material tank 102. The engagement of the sealing ring 115 with the sealing groove 110 and the engagement of the sealing ring 116 with the sealing groove 112 can maintain the sealing performance of the connecting pipe 113 when it is screwed with the inner pipe 109, preventing the raw material or water from leaking out. The sliding engagement of the limiting groove 122 with the protrusion 123 can ensure that when the double-chamber adjusting column 103 is sleeved with the raw material tank 102, the center of the outer pipe 111 can be aligned with the center of the inner pipe 109, so as to facilitate the screwing of the connecting pipe 113.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
