Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical waste liquid treatment technology, and in particular to a pharmaceutical waste liquid treatment device. Background Technology

[0002] Aluminum liquid cooling plates, as high-efficiency heat dissipation components, are widely used in new energy vehicles, electronic servers and other fields. The removal of deposits in their flow channels and the protection of their surface against corrosion directly affect the system's heat dissipation efficiency and service life. Currently, physical and chemical methods are used to clean the flow channels inside aluminum liquid cooling plates. During chemical cleaning, chemicals are usually introduced into the flow channels inside the aluminum liquid cooling plates to remove the internal dirt. Then, the industry generally uses storage tanks to initially collect the waste liquid of the chemicals and then transfers it to professional hazardous waste treatment facilities for further disposal.

[0003] Most storage tanks currently used in the industry have simple structures and only have basic storage functions. They lack protective designs for the characteristics of chemical waste liquids. For example, some aluminum-containing chemical cleaning waste liquids are prone to chemical reactions to generate hydrogen gas during storage. The continuous accumulation of hydrogen gas will cause the gas pressure inside the storage tank to rise sharply. If it cannot be discharged in time, it is very easy to cause the storage tank to expand and deform, or even cause physical explosions, which seriously threaten the safety of personnel and the surrounding environment.

[0004] Therefore, it is necessary to provide a new pharmaceutical waste liquid treatment device to solve the above-mentioned technical problems. Utility Model Content

A vertically arranged vent pipe communicating with the curved hollow handle is fixedly installed inside the storage tank, and multiple annularly distributed annular air inlets are opened on the pipe wall of the vent pipe.

[0007] The vent pipe is equipped with an opening and closing component, and the opening and closing component includes a sealing ring. The sealing ring is sleeved on the vent pipe, and a spring is fixedly installed on the upper ring surface of the sealing ring. The other end of the spring is fixedly connected to an abutment ring fixedly sleeved on the vent pipe.

[0008] The storage tank has a liquid inlet at the top, and a liquid inlet pipe is fixedly installed on the liquid inlet. A piston plate is slidably connected to the liquid inlet pipe, and the piston plate is sleeved on the vent pipe through a through hole and slidably connected to the vent pipe.

[0009] Preferably, a support rod is fixedly installed at the bottom of the vent pipe, and the other end of the support rod is fixedly connected to the inner bottom wall of the storage tank. The diameter of the support rod is larger than the diameter of the vent pipe.

[0010] Preferably, an air guide pipe that communicates with the curved hollow handle is fixedly installed inside the air collecting cylinder, and the air guide pipe is close to the inner bottom wall of the air collecting cylinder.

[0011] Preferably, a piston disc is slidably connected to the air guide pipe, and the air collecting cylinder is divided into upper and lower air chambers by the piston disc. A one-way exhaust valve communicating with the upper air chamber is installed at the top of the air collecting cylinder, and an air nozzle communicating with the lower air chamber is installed on the side wall of the air collecting cylinder near the bottom.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 5 The present invention provides a pharmaceutical waste liquid treatment device, which includes a storage tank 1, a gas collecting cylinder 2, a curved hollow handle 5, a vent pipe 6, and an opening and closing component 7.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 5 A gas collecting cylinder 2 is fixedly installed on the side wall of the storage tank 1. A liquid inlet 11 is opened on the top of the storage tank 1, and a liquid inlet pipe 3 is fixedly installed on the liquid inlet 11. A piston plate 4 with sliding connection is sleeved on the liquid inlet pipe 3. A liquid outlet 12 is opened on the side wall of the storage tank 1 near the bottom, and a sealing cap 13 is installed on both the liquid inlet 11 and the liquid outlet 12.

[0026] It should be noted that the waste liquid used to clean the flow channel of the aluminum liquid cooling plate is collected in the storage tank 1. The waste liquid falls into the storage tank 1 through the liquid inlet pipe 3 and is then stored. The sealing cap 13 of the liquid inlet 11 is then closed. Later, the storage tank 1 is transferred to a qualified hazardous waste treatment company and the waste liquid is discharged through the liquid outlet 12.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 5A curved hollow handle 5, which communicates with the gas collecting cylinder 2, is fixedly installed on the top of the gas collecting cylinder 2. A vertically arranged vent pipe 6, which communicates with the curved hollow handle 5, is fixedly installed inside the storage tank 1. Multiple annularly distributed air inlets 6a are opened on the pipe wall of the vent pipe 6. An opening and closing component 7 is installed on the vent pipe 6. The opening and closing component 7 includes a sealing ring 71, which is sleeved on the vent pipe 6. A spring 72 is fixedly installed on the upper ring surface of the sealing ring 71. The other end of the spring 72 is fixedly connected to the abutment ring 61, which is fixedly sleeved on the vent pipe 6. The piston plate 4 is sleeved on the vent pipe 6 through the opened through hole and is slidably connected to the vent pipe 6. A support rod 62 is fixedly installed at the bottom of the vent pipe 6. The other end of the support rod 62 is fixedly connected to the inner bottom wall of the storage tank 1. The diameter of the support rod 62 is larger than the diameter of the vent pipe 6.

[0028] An air collecting cylinder 2 is fixedly installed with an air guide pipe 8 that communicates with the curved hollow handle 5. The air guide pipe 8 is close to the inner bottom wall of the air collecting cylinder 2. A piston disc 9 that is slidably connected is fitted on the air guide pipe 8. The piston disc 9 divides the air collecting cylinder 2 into upper and lower air chambers. A one-way exhaust valve 21 that communicates with the upper air chamber is installed on the top of the air collecting cylinder 2. An air nozzle 22 that communicates with the lower air chamber is installed on the side wall of the air collecting cylinder 2 near the bottom.

[0029] It should be noted that in the initial state, since the diameter of the support rod 62 is larger than the diameter of the vent pipe 6, the piston plate 4 sits on the end of the support rod 62. At this time, the sealing ring 71 abuts against the piston plate 4 under the action of the spring 72 and seals the annular air inlet 6a.

[0030] When the aluminum-containing chemical cleaning waste liquid stored in storage tank 1 undergoes a chemical reaction to generate hydrogen gas, the gas accumulates continuously in storage tank 1, causing the gas pressure inside storage tank 1 to continuously increase. Therefore, piston plate 4 slides upwards along vent pipe 6 and inlet pipe 3. At this time, sealing ring 71 slides upwards along vent pipe 6 while compressing spring 72. When piston plate 4 passes annular inlet 6a, the hydrogen gas generated in storage tank 1 can enter vent pipe 6 from annular inlet 6a, then enter the curved hollow handle 5 from vent pipe 6, and subsequently enter the gas collecting cylinder 2 from the curved hollow handle 5. In the lower gas chamber, when the amount of hydrogen in the lower gas chamber of the gas collecting cylinder 2 increases, the piston disc 9 slides up along the gas guide pipe 8, thus venting the gas in the upper gas chamber of the gas collecting cylinder 2 through the one-way exhaust valve 21. This allows the hydrogen to be stored smoothly in the gas collecting cylinder 2, avoiding the safety hazard of the storage tank 1 expanding or even physically exploding due to excessive hydrogen accumulation causing a sharp increase in pressure. Therefore, the automatic collection of hydrogen is achieved, and the risk of explosion caused by excessive pressure in the storage tank 1 is avoided. Compared with the existing fixed exhaust structure, the safety is greatly improved.

[0031] Subsequently, professional staff will discharge the hydrogen collected in the gas collecting cylinder 2 through the gas nozzle 22 and carry out safe treatment.

[0032] In addition, the storage tank 1, the gas collecting cylinder 2 and the piston plate 4 of this application are made of high-density polyethylene (HDPE) material, and in order to eliminate the spring 72, stainless steel or titanium alloy springs are used to improve corrosion resistance. At the same time, polytetrafluoroethylene (PTFE) coating is applied to the surface of spring 72 to enhance rust prevention.

[0033] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
