A methylbenzoyl chloride finished product transfer tank

Abstract

This utility model discloses a methylbenzoyl chloride product transfer tank, relating to the technical field of benzoyl chloride equipment. The utility model includes a tank body with an adjustment mechanism in the middle for convenient storage and transfer of the methylbenzoyl chloride product. The adjustment mechanism includes a scraping assembly comprising an outer shell fixedly installed at the bottom of the tank body. During drainage, an external pumping device draws liquid through a pipeline. As the liquid level drops, the PLC control system activates an electric actuator, whose drive end retracts, causing the connecting plate, connecting rod, and piston to descend synchronously and smoothly. The piston edge remains in close contact with the inner wall of the tank, acting like a "scraper" as the liquid level descends, scraping off the methylbenzoyl chloride adhering to the tank wall and pushing it to the bottom for complete discharge through the pipeline. This avoids waste of raw materials caused by liquid adhering to the wall, reduces residue, lowers the difficulty of subsequent cleaning, and improves the efficiency and economy of the transfer tank.

Description

Technical Field

[0001] This utility model relates to the technical field of equipment for benzoyl chloride, specifically a methylbenzoyl chloride finished product transfer tank. Background Technology

[0002] Benzoyl chloride is an organic compound with the chemical formula C7H5ClO. It is a colorless, fuming liquid that is soluble in ether, chloroform, benzene, and carbon disulfide. It is generally used as a dye intermediate, initiator, ultraviolet absorber, rubber and plastic additive, and in pharmaceuticals. Benzoyl chloride is a colorless liquid with an irritating odor. It is soluble in ether, chloroform, and benzene. It gradually decomposes in water or ethanol to produce benzoic acid or ethyl benzoate and hydrogen chloride. Inhalation of leaked benzoyl chloride poses a significant health hazard.

[0003] Referring to the patent document: Patent Publication No. CN222539441U, Patent Publication Date 2025-02-28, a high-efficiency storage tank for benzoyl chloride is disclosed, including a tank body. A rubber stopper is snapped into the top inlet of the tank body, and a rotary joint is installed at the top outlet of the tank body. An output pipe is provided inside the tank body, and the top end of the output pipe is connected to the rotary joint. A corrugated telescopic tube is connected to the rubber stopper, and the top end of the corrugated telescopic tube is connected to the rotary joint via a connecting pipe. The rubber stopper is hollow inside, with an open bottom. The rubber stopper is connected to the inside of the output pipe through the corrugated telescopic tube, the connecting pipe, the rotary joint, and the output pipe. The rubber stopper, corrugated telescopic tube, connecting pipe, rotary joint, and output pipe bridge between two tank bodies, allowing adjacent tanks to communicate with each other. This ensures that multiple tanks are arranged sequentially and interconnected during filling operations, enabling filling of multiple tanks without moving the initial tank positions, effectively improving the efficiency of tank filling.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found: Existing storage tanks for storing p-methylbenzoyl chloride often leave some liquid adhering to the inner surface of the tank during extraction, leading to liquid waste and increased cleaning burden. Furthermore, the existing storage tanks have limitations in their support structure design. Fixed supports make tank movement difficult, while casters at the bottom, though facilitating relocation, may cause accidental movement due to accidental contact or external vibrations while stationary, increasing the risk of collision.

[0005] Therefore, this utility model provides a methylbenzoyl chloride finished product transfer tank. Utility Model Content

[0006] To address the issues of material waste caused by residue on the inner wall of current methylbenzoyl chloride transfer tanks, and the inability of the support design to balance ease of movement and stability at rest, the purpose of this utility model is to provide a methylbenzoyl chloride finished product transfer tank.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a methylbenzoyl chloride product transfer tank, comprising a tank body, wherein an adjustment mechanism is provided in the middle of the tank body for facilitating the storage and transfer of the methylbenzoyl chloride product, the adjustment mechanism comprising: The scraping assembly includes an outer shell fixedly installed at the bottom of the tank, two symmetrically distributed electric push rods fixedly installed at the top of the outer shell, a connecting plate at the top of the tank, the bottom of the connecting plate fixedly installed at the drive end of the electric push rods, a pipe fixedly installed in the middle of the tank, a piston slidably mounted in the middle of the tank, the outer side of the piston contacting the inner surface of the tank, and two symmetrically distributed connecting rods fixedly installed at the top of the piston, the tops of the two connecting rods being fixedly installed at the bottom center of the connecting plate; A movable component, located at the bottom of the tank, is used to facilitate the movement and transportation of the finished methylbenzoyl chloride product.

[0008] Preferably, the moving component includes four fixed frames rotatably mounted on the bottom of the outer casing. Each of the four fixed frames has two symmetrically distributed connecting rods rotatably mounted on its lower part. A roller is rotatably mounted on the middle of one side of each pair of connecting rods. Cylinders are mounted on both sides of the four fixed frames via fisheye bearings. The drive ends of the multiple cylinders are mounted on one side of the connecting rods via fisheye bearings.

[0009] Preferably, the connecting plate has a groove in the middle, and the upper part of the pipe is fitted with a sealing plug.

[0010] Preferably, a pressure valve is fixedly installed at the top of the tank, and the sensor of the pressure valve passes through one side of the piston.

[0011] Preferably, two symmetrically distributed bases are fixedly installed at the bottom of the outer shell, and both bases are provided with shock-absorbing pads at their bottom ends.

[0012] Preferably, the roller is made of high-strength nylon material in one piece, and its shape is a drum-shaped structure with the center protruding outward, and the outer peripheral surface is provided with anti-slip texture.

[0013] Beneficial effects This invention provides a transfer tank for methylbenzoyl chloride products. Compared with the prior art, it has the following advantages: 1. This application enables an external pumping device to draw liquid through a pipeline during drainage. As the liquid level drops, the PLC control system activates the electric actuator, whose drive end retracts to drive the connecting plate, connecting rod, and piston to descend synchronously and smoothly. The piston edge remains in close contact with the inner wall of the tank, acting like a "scraper" as the liquid level drops, scraping off the methylbenzoyl chloride adhering to the tank wall and pushing it to the bottom for complete discharge through the pipeline. This avoids waste of raw materials caused by liquid adhering to the wall, reduces residue, lowers the difficulty of subsequent cleaning, and improves the efficiency and economy of the transfer tank.

[0014] 2. When the tank is being moved, the cylinder extends and pushes the connecting rod downwards to rotate, causing the four rollers to touch the ground simultaneously and lift the tank, allowing the base to detach from the ground. The operator can then use the rotational characteristics of the rollers to easily and flexibly move the tank to the target work position. When it needs to be fixed after arrival, the cylinder retracts the connecting rod in the opposite direction, the rollers are lifted off the ground, and the tank is stably supported by the base, making it easy to move while also being stable and secure during storage.

[0020] 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.

[0021] Please see Figure 1-4This utility model provides a technical solution: a methylbenzoyl chloride product transfer tank, including a tank body 1, which is welded from 316L stainless steel and has an overall cylindrical structure. An adjustment mechanism 2 is provided in the middle of the tank body 1 to facilitate the storage and transfer of the methylbenzoyl chloride product. The adjustment mechanism 2 includes: The scraping assembly 21 includes an outer shell 216 fixedly installed at the lower part of the tank body 1. Two symmetrically distributed electric actuators 211 are fixedly installed at the top of the outer shell 216. A connecting plate 212 is provided at the top of the tank body 1. The bottom end of the connecting plate 212 is fixedly installed at the drive end of the electric actuators 211. A pipe 214 is fixedly installed in the middle of the tank body 1. The pipe 214 is fixed to the middle of the tank body 1 by welding, and the bottom end of the pipe 214 is located at the bottom end of the tank body 1. It can be connected to an external water pump to extract methylbenzoyl chloride through the pipe 214. At the same time, during filling, methylbenzoyl chloride is also poured into the tank through the pipe 214. Inside the tank 1, a piston 215 is slidably mounted in the middle of the tank 1. The outer side of the piston 215 is in contact with the inner surface of the tank 1. Two symmetrically distributed connecting rods 213 are fixedly installed on the top of the piston 215. The tops of the two connecting rods 213 are fixedly installed in the middle of the bottom of the connecting plate 212. When extracting methylbenzoyl chloride, the liquid level gradually drops. At the same time, the electric push rod 211 is gradually driven by the PLC control system. Through the transmission of the connecting plate 212 and the connecting rods 213, the piston 215 moves down synchronously with the liquid level to scrape the inner surface of the tank 1, so as to avoid the liquid sticking to the wall, which would cause waste and affect subsequent cleaning. The movable component 22 is located at the bottom of the tank 1 to facilitate the movement and transportation of the finished methylbenzoyl chloride product.

[0022] The moving assembly 22 includes four fixed brackets 221 rotatably mounted on the bottom of the outer casing 216. Each of the four fixed brackets 221 has two symmetrically distributed connecting rods 223 rotatably mounted on its lower part. A roller 224 is rotatably mounted on the middle of one side of each pair of connecting rods 223. Cylinders 222 are mounted on both sides of the four fixed brackets 221 via fisheye bearings. The drive ends of the multiple cylinders 222 are mounted on one side of the connecting rods 223 via fisheye bearings. When moving, the cylinders 222 can drive the connecting rods 223 to move downward so that the rollers 224 contact the ground downward, thereby supporting the tank 1. At this time, by pulling the tank 1, the tank 1 can be easily moved under the rotation of the rollers 224.

[0023] A groove 2141 is provided in the middle of the connecting plate 212, and a sealing plug 2142 is movably mounted on the upper part of the pipe 214. The groove 2141 facilitates the connection between the pipe 214 and the external liquid extraction equipment. The sealing plug 2142 is made of polytetrafluoroethylene and has a round handle on the top for easy insertion and removal by the operator. At the same time, a fluororubber sealing ring is provided at the contact point between the sealing plug 2142 and the pipe 214 to ensure a sealing effect and prevent the volatilization and leakage of methylbenzoyl chloride during storage. A pressure valve 218 is fixedly installed at the top of the tank 1. The sensor of the pressure valve 218 passes through one side of the piston 215. The pressure valve 218 can detect the pressure of the lower cavity storing methylbenzoyl chloride through the sensor at the bottom. When the pressure exceeds the threshold, an early warning can be issued to remind the staff to check. At the same time, the pressure valve 218 can adjust the pressure of the upper cavity of the piston 215 that does not store methylbenzoyl chloride.

[0024] Two symmetrically distributed bases 217 are fixedly installed at the bottom of the outer shell 216. Both bases 217 are equipped with shock-absorbing pads at their bottom ends. When the tank is in place, the cylinder 222 can reverse the direction to move its rollers 224 upward, causing the bases 217 and shock-absorbing pads to contact the ground. The shock-absorbing pads are made of nitrile rubber, which can reduce the vibration generated during the placement or movement of the transfer tank.

[0025] The roller 224 is made of high-strength nylon material in one piece. Its shape is a drum-shaped structure that bulges outward from the center, and the outer circumference is provided with anti-slip texture.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] During operation, when it is necessary to fill the tank 1 with methylbenzoyl chloride, the operator first removes the sealing plug 2142 at the top of the pipe 214 using the handle, and connects the external filling pipe to the pipe 214. During the filling process, the liquid level in the tank rises, and the piston 215 moves upward synchronously driven by the electric push rod 211. After filling is completed, the sealing plug 2142 is reinserted to ensure a seal. During storage, the cylinder 222 retracts, driving the connecting rod 223 to rotate upward, causing the roller 224 to lift off the ground. At this time, the entire tank 1 is stably supported on the ground by the base 217 at the bottom of the outer shell 216 and its shock-absorbing pads, preventing accidental movement. The pressure valve 218 at the top of the tank 1 monitors the pressure in the lower cavity in real time. If the pressure exceeds the limit due to temperature changes or abnormal reactions, an early warning will be issued immediately to ensure storage safety. When it is necessary to drain the liquid through pipe 214, the external pumping equipment is connected to pipe 214 and starts working. As the liquid level in the tank drops, the control system synchronously starts two electric actuators 211. The drive end of the electric actuator 211 slowly retracts, driving the connecting plate 212, connecting rod 213 and piston 215 fixed thereto to descend synchronously and smoothly. The edge of piston 215 always keeps in close contact with the inner wall of tank 1, like a moving "scraper". As the liquid level drops, this process can scrape off the residual methyl benzoyl chloride liquid adhering to the inner wall of tank 1 and push it to the bottom, where it is completely discharged through pipe 214. When tank 1 needs to be moved, cylinder 222 extends, pushing connecting rod 223 downwards, ultimately causing all four rollers 224 to simultaneously contact the ground, lifting the entire tank 1 and raising base 217 off the ground. At this point, the operator can easily push tank 1, utilizing the omnidirectional rotation of rollers 224 to flexibly move the transfer tank to the target workstation. Upon reaching the designated position, cylinder 222 reverses its movement, retracting connecting rod 223, lifting rollers 224 off the ground, and tank 1 is once again stably supported by base 217, completing the movement process.
