Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an ozone oxidation tank. Background Technique

[0002] As a strong oxidant, ozone can oxidize organic substances including olefins, amines, carbocycles, aromatic compounds, etc. Compared with other oxidants, ozone has the advantages of strong oxidation ability and fast reaction speed; moreover, after the reaction, ozone decomposes by itself without residue and is pollution-free to the environment. Therefore, ozone is widely used in the fields of wastewater treatment, disinfection and sterilization, and chemical synthesis.

[0003] An ozone oxidation tank provided by the publication number "CN219636961U" is equipped with an ultraviolet germicidal lamp, so that the oxidation tank has the function of disinfection and sterilization. The purple light emitted by the ultraviolet germicidal lamp can disinfect the sewage in the oxidation tank. By setting a nut seat and a lead screw, the rotating lead screw will drive the ultraviolet germicidal lamp to move horizontally. The horizontally moving ultraviolet germicidal lamp can disinfect the sewage evenly.

[0004] However, the above technical solutions and the existing technologies have the following defects:

[0005] First, the bottom pipe and the air outlet pipe in this ozone oxidation tank are of a fixed structure, resulting in that the air outlet pipe can only discharge ozone gas upward during actual use and cannot discharge ozone gas around, so that the ozone gas cannot quickly perform comprehensive ozone oxidation treatment on the sewage. And when the air pump does not work, the sewage inside the oxidation tank is likely to flow into the air pump through the air outlet pipe, the bottom pipe and the first air pipe. Once the sewage flows into the air pump, it will cause damage to it. Secondly, when the ultraviolet germicidal lamp in this ozone oxidation tank moves horizontally left and right, it needs the staff to repeatedly control the forward and reverse rotation of the motor to achieve, and the practicability is poor. Content of the Utility Model

[0006] The purpose of the utility model is to provide an ozone oxidation tank to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] An ozone oxidation tank includes an oxidation tank body, a water inlet valve and a drain valve. The water inlet valve is installed on the upper side of the front end face of the oxidation tank body, and the drain valve is installed on the lower side of the front end face of the oxidation tank body. An auxiliary disinfection component is arranged on the upper end face of the oxidation tank body, and the auxiliary disinfection component is used for ultraviolet disinfection of the sewage inside the oxidation tank body.

[0010] Preferably, the auxiliary disinfection component includes a driving pulley, a driven pulley, a reciprocating lead screw, a displacement seat, an ultraviolet disinfection lamp, and a support plate. A driving pulley is arranged on the right side of the circumferential side of the transmission shaft. The upper end surface of the oxidation tank body is fixedly connected to a support plate. A driven pulley is installed above the driving pulley. A reciprocating lead screw is arranged on the left end surface of the driven pulley. A displacement seat is installed on the circumferential side of the reciprocating lead screw. An ultraviolet disinfection lamp is installed on the lower end surface of the displacement seat.

[0011] Preferably, a limiting cross beam is fixedly connected to the upper side of the inner wall of the support plate.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By operating the ozone generator and the air pump, the air pump can blow the ozone gas produced by the ozone generator into the conveying cavity. Then, the ozone gas will enter the aeration head through the connecting pipe and the check valve. Finally, the aeration head will discharge the ozone gas into the sewage for ozone oxidation treatment. By driving the transmission shaft to rotate slowly by the low-speed motor, the transmission shaft can drive the aeration head to rotate together through the connecting pipe and the check valve, thereby further increasing the range of the ozone gas discharged by the aeration head, so that the ozone gas can quickly perform comprehensive ozone oxidation treatment on the sewage, and the check valve can also prevent the sewage from flowing back into the connecting pipe;

And during this process, there is no need for the staff to repeatedly control the forward and reverse rotation of the motor, which has good practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] An auxiliary disinfection component 3 is arranged on the upper end face of the oxidation tank body 1, and the auxiliary disinfection component 3 is used for ultraviolet disinfection of the sewage inside the oxidation tank body 1. A treatment component 4 is arranged on the lower side inside the oxidation tank body 1, and the treatment component 4 is used for ozone oxidation treatment of the sewage inside the oxidation tank body 1. A control panel is installed on the left side of the front end face of the oxidation tank body 1, and the control panel is respectively connected with a low-speed motor 45, an air pump 47, an ozone generator 48 and an ultraviolet disinfection lamp 37 through wires. The control panel facilitates the staff to control the operation of the low-speed motor 45, the air pump 47, the ozone generator 48 and the ultraviolet disinfection lamp 37 respectively according to requirements. Since the internal detailed structure and working principle of the control panel are both relatively mature technologies in the prior art, no further elaboration will be made here.

[0029] The treatment component 4 includes an aeration head 41, a check valve 42, a connecting pipe 43, a transmission shaft 44, a delivery cavity 46, an air pump 47 and an ozone generator 48. The transmission shaft 44 is installed on the lower side inside the oxidation tank body 1. The transmission shaft 44 is connected with the connecting pipe 43 and the driving pulley 31 by welding. The transmission shaft 44 can support the connecting pipe 43. An axial seal retaining ring is embedded on the left end face of the transmission shaft 44, and the axial seal retaining ring matches the outlet of the air pump 47. The axial seal retaining ring makes the seal between the outlet of the air pump 47 and the transmission shaft 44 better. A delivery cavity 46 is opened inside the transmission shaft 44. The delivery cavity 46 can deliver the ozone gas conveyed by the air pump 47 into the connecting pipe 43. The left end of the transmission shaft 44 is butted against the air pump 47. The inlet of the air pump 47 is communicated with the outlet of the ozone generator 48. The outlet of the air pump 47 is communicated with the inlet of the delivery cavity 46. When the air pump 47 is working, it can actively blow the ozone produced by the ozone generator 48 into the delivery cavity 46. The inlet of the air pump 47 is connected with the ozone generator 48. When the ozone generator 48 is working, it can produce ozone gas. Since the internal detailed structure and working principle of the air pump 47 and the ozone generator 48 are both relatively mature technologies in the prior art, no further elaboration will be made here.

[0030] On the upper and lower sides of the annular side surface of the transmission shaft 44, connecting pipes 43 are symmetrically arranged. There are multiple connecting pipes 43, and the specifications of the multiple connecting pipes 43 are the same. The connecting pipes 43 are respectively connected to the inlets of the check valves 42 and the communication cavity. The connecting pipes 43 can not only support the check valves 42, but also convey the ozone gas inside the communication cavity to the check valves 42. The upper ends of the connecting pipes 43 are equipped with check valves 42. There are multiple check valves 42, and the specifications of the multiple check valves 42 are the same. The check valves 42 prevent sewage from flowing back into the connecting pipes 43 through the aeration heads 41. The outlets on the upper end faces of the check valves 42 are equipped with aeration heads 41. There are multiple aeration heads 41, and the specifications of the multiple aeration heads 41 are the same. The multiple aeration heads 41 can spray the ozone gas outwards, so that the ozone gas is fully mixed with the surrounding sewage. The right end of the transmission shaft 44 is equipped with a low-speed motor 45. When the low-speed motor 45 is working, it can drive the transmission shaft 44 to rotate at a low speed. On the left and right sides of the inner wall of the oxidation tank body 1, mechanical seals 11 are symmetrically installed, and the mechanical seals 11 match the transmission shaft 44. The mechanical seals 11 make the sealing between the transmission shaft 44 and the oxidation tank body 1 better. The lower side of the left end face of the oxidation tank body 1 is fixedly connected with a first support platform 12, and the first support platform 12 can support the ozone generator 48 and the air pump 47. The lower side of the right end face of the oxidation tank body 1 is fixedly connected with a second support platform 13, and the second support platform 13 can support the low-speed motor 45.

[0031] Embodiment 2:

[0032] On the basis of Embodiment 1, in this embodiment, when the transmission shaft 44 rotates at a low speed, it will also drive the driving pulley 31 to rotate together, so that the driving pulley 31 drives the reciprocating lead screw 34 to rotate at a low speed through the transmission belt 32 and the driven pulley 33, so that the reciprocating lead screw 34 drives the ultraviolet disinfection lamp 37 to move left and right reciprocally through the displacement seat 35 to uniformly assist in disinfecting the sewage inside the oxidation tank body 1.

[0033] The auxiliary disinfection component 3 includes a driving pulley 31, a driven pulley 33, a reciprocating lead screw 34, a displacement seat 35, an ultraviolet disinfection lamp 37 and a support plate 39. A driving pulley 31 is arranged on the right side of the circumferential side of the transmission shaft 44. A transmission belt 32 is connected between the driving pulley 31 and the driven pulley 33. The driving pulley 31 can drive the driven pulley 33 to rotate through the transmission belt 32. The upper end surface of the oxidation tank body 1 is fixedly connected with a support plate 39. The support plate 39 can support the reciprocating lead screw 34 and the limit cross beam 38. A driven pulley 33 is installed above the driving pulley 31. The driven pulley 33 is connected with the reciprocating lead screw 34 by welding. The driven pulley 33 can drive the reciprocating lead screw 34 to rotate. The reciprocating lead screw 34 is arranged on the left end surface of the driven pulley 33. A displacement seat 35 is installed on the circumferential side of the reciprocating lead screw 34. A sliding cavity is formed inside the displacement seat 35, and the sliding cavity matches the reciprocating lead screw 34. The reciprocating lead screw 34 can drive the displacement seat 35 to move left and right reciprocally through the sliding cavity without changing the rotation direction, so that the displacement seat 35 can drive the ultraviolet disinfection lamp 37 to move left and right reciprocally together. Since the internal detailed structure and working principle of the reciprocating lead screw belong to relatively mature technologies in the prior art, no more details will be described here.

[0034] An ultraviolet disinfection lamp 37 is installed on the lower end surface of the displacement seat 35. The short-wave sterilizing ultraviolet rays radiated outward by the ultraviolet disinfection lamp 37 during power-on can disinfect the surrounding sewage. A limit cross beam 38 is fixedly connected to the upper side of the inner wall of the support plate 39. A limit groove 381 is formed on the lower end surface of the limit cross beam 38, and the limit groove 381 matches the displacement seat 35. The limit cross beam 38 and the limit groove 381 can limit and guide the displacement seat 35 to prevent the displacement seat 35 from shaking or shifting during use. A transparent protective cover 36 is installed on the lower end surface of the displacement seat 35. The material of the transparent protective cover 36 is transparent acrylic. The transparent protective cover 36 made of transparent acrylic can protect the ultraviolet disinfection lamp 37 while ensuring that the ultraviolet disinfection lamp 37 can radiate sterilizing ultraviolet rays outward, and prevent the ultraviolet disinfection lamp 37 from being eroded by sewage. A limit ring 341 is arranged on the right side of the circumferential side of the reciprocating lead screw 34. The limit ring 341 is connected with the reciprocating lead screw 34 by welding. A circular cover 391 is installed on the right end surface of the support plate 39. The limit ring 341 and the circular cover 391 prevent the reciprocating lead screw 34 from displacing or shaking during use. A wire passing hole is formed in the lower side inside the displacement seat 35. The wire passing hole facilitates the external wire to penetrate inside the displacement seat 35 to electrically connect the ultraviolet disinfection lamp 37.

[0035] Working principle: First, the staff opens the water inlet valve 2 to introduce an appropriate amount of sewage into the oxidation tank body 1. During this process, the water level of the sewage inside the oxidation tank body 1 should not exceed the height of the outlet of the water inlet valve 2. Then, the ozone generator 48 and the air pump 47 can be operated through the control panel. The ozone generator 48 is used to produce ozone gas, and the air pump 47 blows the ozone gas into the delivery chamber 46. Then, the ozone gas passes through the connecting pipe 43 and the check valve 42 and enters the aeration head 41. Finally, the aeration head 41 discharges the ozone gas into the sewage, thereby performing ozone oxidation treatment on the sewage inside the oxidation tank body 1. When it is necessary to provide the exhaust range of the aeration head 41, the staff only needs to start the low-speed motor 45 through the control panel, and the low-speed motor 45 can drive the transmission shaft 44 to rotate at a low speed. The transmission shaft 44 drives the aeration head 41 to rotate together through the connecting pipe 43 and the check valve 42, thereby further increasing the exhaust range of the ozone gas discharged by the aeration head 41. While the transmission shaft 44 rotates at a low speed, it also drives the driving pulley 31 to rotate together, and the driving pulley 31 drives the reciprocating lead screw 34 to rotate at a low speed through the transmission belt 32 and the driven pulley 33. At this time, the reciprocating lead screw 34 rotating at a low speed drives the displacement seat 35 to move left and right reciprocally, and the displacement seat 35 drives the ultraviolet disinfection lamp 37 to move left and right reciprocally. At the same time, the ultraviolet disinfection lamp 37 is powered on through the control panel to work, so that the short-wave sterilizing ultraviolet rays radiated outward by the working lamp can disinfect the surrounding sewage, and the ultraviolet disinfection lamp 37 moving left and right reciprocally can disinfect the sewage inside the oxidation tank body 1 comprehensively. When the sewage disinfection treatment reaches the required time, the staff first turns off the ultraviolet disinfection lamp 37 and the low-speed motor 45 respectively, and then turns off the air pump 47 and the ozone generator 48 respectively. At this time, opening the drain valve 5 can discharge the treated sewage inside the oxidation tank body 1.
