Abstract
Description
Technical Field
[0001] This utility model relates to the field of benzyl chloride turnover tank technology, specifically a quantitative interlocking device for benzyl chloride turnover tank. Background Technology
[0002] A benzyl chloride transfer tank is a container used for storing and transporting benzyl chloride, an important organic chemical intermediate with the chemical formula C7H7Cl. It is a colorless or slightly yellow transparent liquid with a pungent odor. It is insoluble in water but miscible with most organic solvents such as ethanol, chloroform, and ether.
[0003] Benzyl chloride is highly corrosive and toxic. If the filling volume exceeds the safe capacity of the storage tank, it may cause material overflow or abnormal increase in tank pressure, which may lead to leakage or even explosion. Existing benzyl chloride turnover filling lacks a quantitative interlocking structure and cannot automatically stop feeding when the set value is reached. Manual filling is prone to overfilling problems.
[0004] Therefore, it is particularly important to design a quantitative interlocking device for benzyl chloride turnover tanks to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:
[0024] A quantitative interlocking device for a benzyl chloride turnover tank includes a turnover tank body 1. A fixed inlet pipe 2 is connected to the left end of the top of the outer side of the turnover tank body 1. An outer pipe 3 is inserted into the top of the fixed inlet pipe 2. A lower liquid level sensor 4 is installed on the right side wall inside the turnover tank body 1 near the top. An upper liquid level sensor 5 is installed on the right side wall inside the turnover tank body 1 above the lower liquid level sensor 4. A connecting sleeve 6 is installed at the top of the fixed inlet pipe 2. Folding brackets 601 are installed on both the left and right sides of the connecting sleeve 6. An internal thread seat 602 is installed inside the folding bracket 601. A locking screw 603 is connected to the internal thread of the internal thread seat 602. A pipe clamp 604 that works with the outer pipe 3 is connected to the end of the locking screw 603 facing the outer pipe 3. A buzzer alarm 7 is installed on the outer side of the turnover tank body 1.
[0025] The fixed inlet pipe 2 and the external pipe 3 are connected by plugging and unplugging, and the two are designed to be separable. The tank body 1 and the fixed inlet pipe 2 are both made of special stainless steel. The other end of the locking screw 603 is connected to a handwheel, and the inner side of the pipe clamp 604 is fitted with a rubber sheet to make the clamping more stable and tight.
[0026] In this embodiment, please refer to Figure 3 A sealing valve plate 201 is rotatably connected inside the fixed inlet pipe 2 and located in the middle section. A fixed housing 202 is provided on the right side of the fixed inlet pipe 2. A drive shaft 203 is rotatably connected inside the fixed housing 202. A driven gear 204 is fixedly sleeved on the outside of the drive shaft 203. A rotary motor 205 is installed at the bottom of the inner side of the fixed housing 202. The output end of the rotary motor 205 is connected to a drive gear 206 that meshes with the driven gear 204. A flow monitoring sensor 207 is installed on the inner side wall of the fixed inlet pipe 2 and below the sealing valve plate 201.
[0027] The outer side of the turnover tank 1 is equipped with a control switch, which is connected to the lower liquid level sensor 4, the upper liquid level sensor 5, the rotary motor 205, the flow monitoring sensor 207, and the buzzer alarm 7 by wires, and the connection is electrical. The left end of the drive shaft 203 passes through the fixed housing 202 and extends into the interior of the fixed liquid inlet pipe 2 and is connected to the sealing valve plate 201.
[0028] The working process of this utility model is as follows: The outer connecting pipe 3 is inserted into the inlet of the fixed inlet pipe 2. Then, the locking screw 603 is rotated by turning the handwheel in the internal threaded seat 602 inside the folding bracket 601 until the two sets of pipe clamps 604 clamp and fix the outer connecting pipe 3, preventing leakage at the inlet during filling. A lower liquid level sensor 4 and an upper liquid level sensor 5 are installed inside the container body 1. During filling, the two sets of liquid level sensors monitor the level in real time. When the liquid level reaches the position of the lower liquid level sensor 4, it indicates that the container is about to be full. At this time, a signal is sent... The rotary motor 205 is started, causing the drive gear 206 to mesh with the driven gear 204, thereby driving the shaft 203 to partially close the sealing valve plate 201. Under the monitoring of the flow monitoring sensor 207, the filling flow rate is reduced to avoid the inlet not closing in time when the filling is full. When the filling reaches the position of the upper liquid level sensor 5, the sealing valve plate 201 is driven to fully close and the buzzer alarm 7 is sounded to remind the user, thus completing the sealing. When the preset value is reached, the interlocking structure is triggered, automatically closing the fixed liquid inlet pipe and sounding an alarm to prevent over-storage and over-filling, greatly improving the safety of filling.
