Description
Technical Field
[0001] This utility model relates to the field of methylthioacetaldehyde oxime production technology, specifically to chlorine gas control equipment for methylthioacetaldehyde oxime production. Background Technology
[0002] Carbamate pesticides are a type of organic pesticide widely used in my country. They have advantages such as strong killing power, good penetration, fast effect, broad insecticidal spectrum, low residue, applicability to many crops, and safe use. They are widely used on more than 30 crops such as cotton, cabbage, soybean, tobacco, peanut, and citrus.
[0003] Methomyl oxime, or methomyl for short, is an economically valuable intermediate used in the synthesis of carbamate insecticides such as methomyl, thiodicarb, and fenvalerate. The key to methomyl synthesis lies in the preparation of the intermediate methomyl oxime; different synthetic routes lead to significant differences in the yield and cost of methomyl oxime.
[0004] Chlorine gas poses serious health risks, irritating the eyes, nose, throat, and upper respiratory tract. Existing chlorine control equipment used in the production of methylthioacetaldehyde oxime is ill-suited for timely detection of chlorine leaks. When leaks occur in this equipment, they cannot be detected and addressed promptly, potentially leading to further chlorine contamination and harm. Utility Model Content
[0005] The purpose of this invention is to overcome the problem that existing technologies make it difficult to detect and protect against chlorine leaks, and to provide a chlorine control device for the production of methylthioacetaldehyde oxime.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A chlorine gas control device for the production of methylthioacetaldehyde oxime includes: a sealed box, a one-way valve installed at the bottom of the sealed box, a vacuum pump installed at the top of the sealed box, a chlorine gas tank installed on one side of the vacuum pump, a switch valve installed on one side of the chlorine gas tank, an outlet pipe transversely connected to one side of the interior of the sealed box, a control valve installed on one side of the outlet pipe, a regulating valve installed on one side of the control valve, a regulating device installed at the bottom of the regulating valve, a flow detector installed on one side of the regulating valve, and two chlorine gas sensors fixedly installed on both sides of the top interior of the sealed box.
[0008] In a preferred embodiment, a chlorine gas pipe is installed on one side of the flow detector, and an electronic valve is installed on the other side of the chlorine gas pipe. The electronic valve is a structure for controlling the chlorine gas switch.
[0009] In a preferred embodiment, a manual valve is installed at the bottom of the electronic valve, and a chlorine tank is installed at the bottom of the manual valve. The chlorine tank is a structure for storing chlorine.
[0010] In a preferred embodiment, a support frame is fixedly installed on the outer bottom of the chlorine tank, the support frame being a structure for supporting the chlorine tank.
[0011] In a preferred embodiment, a connecting frame is installed on one side of the sealing box, and a sealing frame is fixedly installed inside the connecting frame. The sealing frame is a structure for fitting and sealing with the sealing plate.
[0012] In a preferred embodiment, a card plate is fixedly installed on the right side of the connecting frame, and a sealing door is rotatably connected to one side of the connecting frame. The sealing door is a structure used to seal one side of the sealing box.
[0013] In a preferred embodiment, a rotating handle is rotatably connected to one side of the sealing door, and a sealing plate is fixedly installed on the other side of the sealing door. The rotating handle is a structure for fitting and connecting with the plate.
[0014] As can be seen from the above, compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This chlorine gas control equipment for the production of methylthioacetaldehyde oxime uses a chlorine gas sensor to detect chlorine gas. When a chlorine gas leak occurs, the sensor detects the leak and triggers an alarm. Simultaneously, it controls the electronic valve and control valve to close, thereby blocking the flow of chlorine gas. After the chlorine gas is shut off, an air pump extracts the chlorine gas from the sealed box and stores it in a chlorine tank. A one-way valve allows outside air to enter the sealed box, preventing chlorine gas from flowing out. This improves the protection effect of the chlorine gas control equipment for the production of methylthioacetaldehyde oxime against chlorine gas leaks and avoids the problem of chlorine gas leakage.
[0016] 2. The chlorine gas control equipment for the production of methylthioacetaldehyde oxime uses a rotating sealing door to close, which causes the sealing plate and sealing frame to fit together, thus sealing the gap. By rotating the handle, the handle and the clamping plate are engaged, thus fixing the sealing door. This improves the sealing effect of the chlorine gas control equipment for the production of methylthioacetaldehyde oxime and avoids the danger of chlorine gas leakage. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Combined with appendix Figures 1-4 In this embodiment, the chlorine gas control equipment for the production of methylthioacetaldehyde oxime includes: a sealed box 1, a one-way valve 11 installed at the bottom of the sealed box 1, a vacuum pump 12 installed at the top of the sealed box 1, a chlorine gas tank 13 installed on one side of the vacuum pump 12, a switch valve 14 installed on one side of the chlorine gas tank 13, an outlet pipe 15 transversely connected to one side of the interior of the sealed box 1, a control valve 16 installed on one side of the outlet pipe 15, a regulating valve 17 installed on one side of the control valve 16, a regulating device 18 installed at the bottom of the regulating valve 17, a flow detector 19 installed on one side of the regulating valve 17, and two chlorine gas sensors 110 fixedly installed on both sides of the top of the interior of the sealed box 1.
[0024] Specifically, the connection is sealed by the sealing box 1 to prevent chlorine gas from leaking into the air. The chlorine gas sensor 110 facilitates the detection of chlorine gas leaks and controls the electronic valve 21 and control valve 16 to close, thereby preventing continuous chlorine gas leakage. The operation of the air pump 12 draws the chlorine gas inside the sealing box 1 into the chlorine tank 13 for storage. The one-way valve 11 sends outside air into the sealing box 1 to maintain pressure balance. The design of the one-way valve 11 also prevents chlorine gas leakage.
[0025] Among them, the control device 18 is a "C8051F020 single-chip microcomputer", the flow detector 19 is a "TUF-1" electronic gas flow meter, and the chlorine sensor 110 is a "ME4-Cl2".
[0026] A chlorine pipe 2 is installed on one side of the flow detector 19, an electronic valve 21 is installed on one side of the chlorine pipe 2, a manual valve 22 is installed at the bottom of the electronic valve 21, a chlorine tank 23 is installed at the bottom of the manual valve 22, and a support frame 24 is fixedly installed on the outer bottom of the chlorine tank 23.
[0027] Specifically, the chlorine tank 23 is supported by the support frame 24, and the chlorine is controlled by a dual-layer system of manual valve 22 and electronic valve 21. This avoids the problem of chlorine leakage that cannot be shut off due to damage to a single valve, thus improving the leak prevention effect of the chlorine control equipment for the production of methylthioacetaldehyde oxime. When the chlorine sensor 110 detects a chlorine leak, the electronic valve 21 is closed, thereby preventing continuous chlorine leakage.
[0028] A connecting frame 3 is installed on one side of the sealed box 1. A sealing frame 31 is fixedly installed inside the connecting frame 3. A card plate 32 is fixedly installed on the right side of the connecting frame 3. A sealing door 33 is rotatably connected to one side of the connecting frame 3. A rotating handle 34 is rotatably connected to one side of the sealing door 33. A sealing plate 35 is fixedly installed on the other side of the sealing door 33.
[0029] Specifically, by rotating and closing the sealing door 33, the sealing plate 35 and the sealing frame 31 are brought into contact, thereby sealing the gap between the sealing door 33 and the connecting frame 3. This prevents chlorine gas from leaking out of the gap and causing a dangerous situation in the event of a chlorine gas leak. By rotating the rotating handle 34, the rotating handle 34 and the clamping plate 32 are fitted together, thereby fixing the sealing door 33 and improving the sealing effect of the chlorine gas control equipment for the production of methylthioacetaldehyde oxime.
[0030] Working Principle: First, the chlorine tank 23 is supported by the support frame 24. The chlorine pipe 2 is connected to the flow detector 19, which facilitates the detection of chlorine flow. The flow detector 19 is connected to the control valve 17, and the control device 18 controls the control valve 17 to regulate the chlorine flow. The control valve 16 can open or close the chlorine flow, improving the convenience of the chlorine control equipment for methylthioacetaldehyde oxime production. During use, when a chlorine leak occurs, the sealing box 1 seals the chlorine, preventing dangerous leakage. Two chlorine sensors 110 on both sides of the top inside the sealing box 1 detect the chlorine leak. Upon detection, the control valve 16 and electronic valve 21 are closed, blocking the chlorine flow and preventing continuous leakage. If the electronic valve 21 malfunctions and cannot close the chlorine, the manual valve 22 manually closes the chlorine, improving the safety of the chlorine control equipment for methylthioacetaldehyde oxime production. Once the chlorine leak is blocked... By operating the vacuum pump 12, the leaked chlorine gas inside the sealed container 1 is extracted and sent to the chlorine tank 13 for storage, thus collecting the chlorine gas. A one-way valve 11 allows outside air to be introduced into the sealed container 1 while the vacuum pump 12 is extracting air, maintaining pressure balance inside the sealed container 1 and preventing chlorine leakage. The storage tank is connected to a switching valve 14, which allows the gas inside the chlorine tank 13 to be released when the valve is opened, improving the efficiency of chlorine gas production for methylthioacetaldehyde oxime. The gas control equipment is convenient. When the equipment needs to be tested, the sealing door 33 can be opened by rotating the handle 34. When closed, the sealing door 33 can be rotated to make the sealing plate 35 on one side of the sealing door 33 fit with the sealing frame 31 inside the connecting frame 3, thereby sealing the gap between the sealing door 33 and the connecting frame 3 and preventing chlorine leakage. Rotating the handle 34 can make the handle 34 and the clamping plate 32 fit together to fix and seal the sealing door 33.
[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
