Description

Technical Field

[0001] The invention relates to the technical field of waste collection and mixing, in particular to a waste collection box for chemical testing. Background Art

[0002] A large amount of waste, waste water, waste gas and waste residue will be generated in the process of chemical testing. In order to achieve reasonable treatment and utilization, it is necessary to adopt corresponding collection and treatment methods for different types of three wastes. In particular, the waste water generated in chemical testing contains a large amount of toxic and harmful substances, such as heavy metals, organic matter, acid and alkali, etc. These substances cause great harm to the environment and human health.

[0003] Chemical wastewater needs to be collected separately according to its acidity and alkalinity, and needs to be neutralized in time to prevent the strong corrosiveness of the wastewater from damaging the storage container and causing leakage. On the other hand, long-term storage may react with other waste liquids or impurities to produce toxic gases, increasing the difficulty and cost of subsequent treatment. Environmental regulations also require that chemical waste liquids must be neutralized and meet safety standards before they can be stored or discharged.

[0004] The existing waste collection box simply holds the chemical waste liquid when collecting it. Generally, the waste liquid is neutralized and transferred after it is full in the collection box. However, the chemical waste liquid is collected multiple times and dispersedly. It takes a certain amount of time before the collection box is full of waste liquid. Storage during this period also poses a great safety hazard. Moreover, it is not easy to control the degree of reaction when a large amount of waste liquid is concentrated together for neutralization, and it is also easy to have incomplete neutralization. Therefore, the existing collection box has the defect of not being able to neutralize the waste liquid in time and completely when collecting the waste liquid generated by chemical testing. Based on this, a waste collection box for chemical testing is proposed. Summary of the invention

[0016] Preferably, the diameters of both the semi-gear and the second toothed ring are 1 / 2 of the diameter of the first toothed ring.

[0024] (2) In the present invention, by setting a controller, when the pH value of the liquid in the collection box changes, the controller controls the pH sensor to detect the pH value of the waste liquid. When the detected pH value exceeds the range, the controller feeds back to the electromagnetic control valve and the driving motor. The electromagnetic control valve is opened so that the neutralizing reagent in the reagent box flows to the dosing pipe.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] As Figure 1-7 shown, a waste collection box for chemical inspection includes a collection box 1, and further includes:

[0035] A liquid inlet hopper 2, which is fixedly arranged on one side of the top of the collection box 1. A sealing cover is provided on the top of the liquid inlet hopper 2, and the liquid inlet hopper 2 is fixedly installed on the top of the collection box 1. A liquid outlet pipe is fixedly provided on one side of the bottom of the collection box 1, and a control valve is provided on the liquid outlet pipe;

[0036] An intermittent liquid discharging assembly, which is arranged on the lower side of the liquid inlet hopper 2 and is used to control the intermittent flow of the waste liquid in the liquid inlet hopper 2 into the collection box 1;

[0037] A reagent box 3, which is fixedly arranged on the other side of the top of the collection box 1. A medicine feeding pipe 4 is fixedly provided at the bottom of the reagent box 3. The medicine feeding pipe 4 penetrates and extends into the collection box 1. An electromagnetic control valve 5 is arranged inside the medicine feeding pipe 4, and the electromagnetic control valve 5 is used to control the opening and closing of the medicine feeding pipe 4;

[0038] An intermittent dosing assembly is provided on the dosing pipe 4 for controlling the intermittent input of the neutralizing reagent in the reagent tank 3 into the collection tank 1;

[0039] A stirring assembly is fixedly arranged in the collection tank 1 for stirring and mixing the waste liquid and the neutralizing reagent in the collection tank 1 evenly;

[0040] A pH sensor 6 is fixedly arranged at the bottom of the collection tank 1 for detecting the pH value of the mixed liquid in the collection tank 1.

[0041] The intermittent dosing assembly includes a control cavity 7 opened in the collection tank 1. One side of the bottom of the control cavity 7 is rotatably connected with a rotating column 8. The top of the rotating column 8 is fixedly connected with a first sealing circular plate 9. One side of the first sealing circular plate 9 penetrates through the dosing pipe 4 and is slidably connected with the dosing pipe 4. The dosing pipe 4 is divided into upper and lower sections. The side of the first sealing circular plate 9 away from the center passes through the middle of the upper and lower sections of the dosing pipe 4, and the surface of the first sealing circular plate 9 is attached to the dosing pipes 4 on both the upper and lower sides, which not only does not affect the rotation of the first sealing circular plate 9 but also can seal the dosing pipe 4. Two dosing holes 10 are symmetrically opened on the first sealing circular plate 9. The positions of the dosing holes 10 correspond to the dosing pipe 4. The inner diameter of the dosing holes 10 is smaller than the inner diameter of the dosing pipe 4. When the dosing holes 10 of the first sealing circular plate 9 rotate to correspond to the dosing pipe 4, the dosing pipe 4 is communicated. Through the continuous rotation of the first sealing circular plate 9, the dosing holes 10 are intermittently communicated with the dosing pipe 4, achieving the effect of intermittently adding the neutralizing reagent into the collection tank 1.

[0042] A driving motor 11 is fixedly arranged on the top of the collection tank 1. The output shaft of the driving motor 11 is fixedly connected with a rotating shaft 12. The rotating shaft 12 penetrates and extends into the control cavity 7 and is fixedly connected with a semi-gear 13. A first toothed ring 14 is fixedly sleeved on the outer wall of the first sealing circular plate 9. The first toothed ring 14 is meshed with the semi-gear 13. The diameter sizes of the semi-gear 13 are all 1 / 2 of the diameter size of the first toothed ring 14.

[0043] By driving the driving motor 11 to drive the rotating shaft 12 and the semi-gear 13 to rotate, the semi-gear 13 meshes with the first toothed ring 14 to rotate, and the first toothed ring 14 drives the first sealing plate 9 to rotate. Since the diameter sizes of the semi-gear 13 are all half of the diameter size of the first toothed ring 14, and the teeth on the semi-gear 13 are only arranged on half of the outer circumference of the semi-gear 13, when the semi-gear 13 rotates one week, the first toothed ring 14 is driven to rotate 1 / 4 week, so that the first sealing circular plate 9 rotates 90° each time and can stay for a certain time, ensuring that when the dosing holes 10 of the first sealing circular plate 9 rotate to correspond to the dosing pipe 4 each time, the neutralizing reagent in the reagent tank 3 can be fully added into the collection tank 1.

[0044] The intermittent liquid discharging assembly includes a liquid guide plate 15 fixedly arranged below the liquid inlet hopper 2. The top of the liquid guide plate 15 is arranged in an inclined plane. A first liquid guide hole 16 is formed on the downward inclined side of the liquid guide plate 15. A second sealing circular plate 17 is rotatably connected below the liquid guide plate 15. The liquid inlet hopper 2, the liquid guide plate 15 and the second sealing circular plate are all circular, and their centers are on the same vertical axis. A second liquid guide hole 18 is formed on the second sealing circular plate 17. The positions of the first liquid guide hole 16 and the second liquid guide hole 18 correspond to each other. The side wall of the second sealing circular plate 17 penetrates through the liquid inlet hopper 2 and is fixedly sleeved with a second gear ring 19. The second gear ring 19 is meshed with the half gear 13. When the half gear 13 meshes with the second gear ring 19, it is separated from the first gear ring 14. The diameter size of the half gear 13 is the same as the diameter size of the second gear ring 19.

[0045] When the half gear 13 rotates to be separated from the first gear ring 14, the half gear 13 meshes with the second gear ring 19 and drives the second gear ring 19 to rotate. The second gear ring 19 drives the second sealing circular plate 17 to rotate. And each time the half gear 13 meshes with the second gear ring 19, it rotates 180°, so that the first liquid guide hole 16 and the second liquid guide hole 18 correspond intermittently. Thus, the liquid in the liquid inlet hopper 2 falls into the collection box 1 intermittently. And when the first liquid guide hole 16 and the second liquid guide hole 18 correspond to each other, the first sealing plate 9 seals the medicine adding pipe 4, so that the waste liquid and the neutralizing reagent are added alternately.

[0046] A controller is fixedly arranged on the outer wall of the collection box 1. The controller is respectively connected with the electromagnetic control valve 5, the pH sensor 6 and the driving motor 11, responsible for data processing and control logic, and used for automatically adjusting the pH value of the waste liquid in the collection box 1. The final range of the pH value adjustment is 7 - 9.

[0047] The controller is used to perform the following steps. Before the driving motor 11 operates and after it stops operating, the first liquid guiding hole 16 and the second liquid guiding hole 18 in the liquid inlet hopper 2 are in a communicating state, facilitating the addition of waste liquid into the collection tank 1. As the waste liquid is continuously added, when the pH value of the liquid in the collection tank 1 changes, the controller controls the pH sensor 6 to detect the pH value of the waste liquid. When the detected pH value exceeds the range, the controller feeds back to the electromagnetic control valve 5 and the driving motor 11. The electromagnetic control valve 5 is opened so that the neutralizing reagent in the reagent tank 3 flows into the medicine adding pipe 4. At the same time, the driving motor 11 starts to drive the rotating shaft 12 and the semi-gear 13 to rotate. The semi-gear 13 meshes with the first gear ring 14 and the second gear ring 19 on both sides to rotate alternately, causing the first sealing circular plate 9 and the second sealing circular plate 17 to rotate alternately. Furthermore, the waste liquid and the neutralizing reagent are added alternately. When the pH sensor 6 detects that the pH value reaches the set range, the controller controls the electromagnetic control valve 5 and the driving motor 11 to close, automatically stopping the addition of the neutralizing reagent, achieving the effect of automatically adjusting the pH value every time waste liquid is poured in.

[0048] An annular sliding groove 20 is formed on the side wall of the liquid inlet hopper 2. The annular sliding groove 20 is formed above the side wall of the liquid inlet hopper 2 at the bottom of the second sealing circular plate 17. A slider 21 is slidably connected in the annular sliding groove 20. The slider 21 is fixedly connected to the bottom of the second sealing circular plate 17, ensuring that when the semi-gear 13 meshes with the second gear ring 19 and rotates, the second gear ring 19 drives the second sealing circular plate 17 to rotate around the center, ensuring that the first liquid guiding hole 16 and the second liquid guiding hole 18 can accurately correspond.

[0049] The stirring assembly includes a rotating shaft 12 rotatably connected to the top of the collection tank 1. The rotating shaft 12 penetrates and extends into the collection tank 1 and is fixedly provided with stirring blades 22. While the driving motor 11 drives the rotating shaft 12 and the semi-gear 13, the stirring blades on the rotating shaft 12 continuously stir the liquid in the collection tank 1, enabling the waste liquid and the neutralizing reagent to be added alternately while being continuously stirred, improving the mixing effect of the two and enhancing the stability of the pH value measured by the pH sensor 6.

[0050] A filter screen 23 is fixedly provided in the liquid inlet hopper 2 to filter solid impurities in the waste liquid, preventing the impurities from affecting the neutralization of the waste liquid and also preventing the impurities from reacting with the neutralizing reagent.

[0051] A liquid level sensor 24 is fixedly provided above the collection tank 1. A buzzer 25 is fixedly provided on an outer wall of one side of the collection tank 1. The liquid level sensor 24 and the buzzer 25 are electrically connected, and both the liquid level sensor 24 and the buzzer 25 are connected to the controller.

[0052] When the liquid level sensor 24 detects that the waste liquid in the collection tank 1 reaches a relatively high liquid level, accounting for 80% of the capacity of the collection tank 1, the buzzer gives an alarm to remind the staff to transfer the waste liquid in the collection tank 1 in time and perform subsequent processing to avoid waste liquid overflow or leakage.

[0053] During use, the waste liquid is added into the collection tank 1 from the feed hopper 2. The filter screen 23 preliminarily filters the larger impurities in the waste liquid. After the waste liquid enters the collection tank 1, the pH sensor 6 detects the pH value of the waste liquid. When the detected pH value exceeds the range, the controller feeds back to the electromagnetic control valve 5 and the drive motor 11. The electromagnetic control valve 5 opens, causing the neutralizing reagent in the reagent tank 3 to flow towards the dosing pipe 4. At the same time, the drive motor 11 starts to drive the rotating shaft 12 and the semi-gear 13 to rotate. The semi-gear 13 meshes with the first gear ring 14 and the second gear ring 19 on both sides to rotate alternately, causing the first sealing circular plate 9 and the second sealing circular plate 17 to rotate alternately. The dosing holes 10 on the first sealing circular plate 9 are intermittently connected to the dosing pipe 4, and the second liquid guiding holes 18 on the second sealing circular plate 17 are intermittently connected to the first liquid guiding holes 16, achieving intermittent addition of the waste liquid and the neutralizing reagent, and the waste liquid and the neutralizing reagent are added alternately. Along with the continuous stirring of the stirring blade 22, the waste liquid added into the collection tank 1 is neutralized in time. And adding in small amounts multiple times can make the two mix more evenly and be neutralized more completely. When the pH sensor 6 detects that the pH value reaches the set range, the controller controls the electromagnetic control valve 5 and the drive motor 11 to close, automatically stopping the addition of the neutralizing reagent, achieving the effect of automatically adjusting the pH value every time the waste liquid is poured, and reducing manual operation, thereby reducing the harm of the waste liquid to the human body.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
