Description

Technical Field

[0001] The invention belongs to the technical field of benzoyl chloride storage, and in particular relates to a storage tank for benzoyl chloride. Background Art

[0002] Benzoyl chloride is an important organic chemical commonly used in organic synthesis and industrial production. It is a colorless liquid with a strong, pungent odor. It is readily soluble in organic solvents such as alcohols, ethers, and chloroform, but insoluble in water. Benzoyl chloride is primarily used to prepare compounds such as benzoic acid, benzaldehyde, and benzoic acid esters, and is widely used in synthetic dyes, fragrances, pharmaceuticals, and agricultural chemicals. Its high reactivity with water, alcohols, and amines makes it a key acylating agent in many organic reactions.

[0003] When storing benzoyl chloride, a dedicated storage tank is used for the storage process. Conventional storage tanks are composed of a sealing tank and a sealing device. When filling and unloading, the sealing device needs to be manually operated to open the feed channel to realize the injection process of benzoyl chloride. However, when operating this type of device, the operating steps must be strictly followed, and the thread locking and flange locking must be kept tight to realize the sealing process. When not in use, quick sealing cannot be achieved. At the same time, more preparation steps are required for filling, and quick filling cannot be achieved.

[0004] When storing benzoyl chloride in a conventional benzoyl chloride storage tank, the air inside the storage tank needs to be evacuated before filling. However, due to the limitations of the exhaust and air intake methods, a small amount of air may be brought into the storage tank when injecting benzoyl chloride, resulting in a decrease in the purity of benzoyl chloride and affecting its storage process. Improvement is urgently needed. Summary of the Invention

[0005] The object of the present invention is to provide a storage tank for benzoyl chloride, to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical scheme: a storage tank for benzoyl chloride, comprising a tank body, a feed port is fixedly connected in the middle of the top end of the tank body, a feed port is fixedly connected at the top end of the feed port, a feed pipe is fixedly connected at the top end of the feed pipe, a second sleeve is fixedly connected at the top end of the second sleeve, a feeding assembly is movably sleeved inside the first sleeve, the feeding assembly moves up and down relative to the first sleeve, a reset assembly is installed at the middle position of the bottom end of the inner cavity of the second sleeve, the top end of the reset assembly is connected to the bottom end of the feeding assembly, limiting holes are provided on the left and right sides of the first sleeve near the top end, a limiting assembly is installed in the middle of the feeding assembly, the left and right sides of the limiting assembly pass through the left and right sides of the feeding assembly, the top end of the feeding assembly is fixedly connected to a No. 1 three-way valve, the top end of the No. 1 three-way valve is connected to an external high-pressure inert gas delivery pipe, and the bottom end of the No. 1 three-way valve is connected to the top end of the limiting assembly; When the reset component is subjected to the ultimate pulling force, the feeding component is at the highest point, and the left and right ends of the limit component are movably connected with the limit hole. The high-pressure inert gas output by the No. 1 three-way valve acts on the limit component and releases the limit between the limit component and the limit hole. The reset component automatically resets and drives the feeding component to move downward, completing the feeding process.

[0007] Before injecting benzoyl chloride, it is necessary to maintain the connection between the top of the No. 1 three-way valve and the external high-pressure inert gas delivery device, and at the same time, maintain the locking relationship between the limit assembly and the limit hole. At this time, the feeding assembly is at the highest point position, completing the preparation before the injection of benzoyl chloride.

[0008] As a further technical solution of the present invention, an air intake valve is fixedly connected to the position near the left side of the top of the tank body, an exhaust valve is fixedly connected to the position near the right side of the top of the tank body, and a protective gas input pipe is fixedly connected to the top of the air intake valve. The end of the protective gas input pipe away from the air intake valve is connected to one side of the No. 1 three-way valve.

[0009] As a further technical solution of the present invention, the intake valve and the exhaust valve are both one-way valves, and the directions of the valves are inward conduction and outward blockage, and outward conduction and inward blockage, respectively, and both are in a normally closed state in the initial state.

[0010] When benzoyl chloride is injected, that is, external high-pressure inert gas is input into the interior of the No. 1 three-way valve, that is, after the gas is input into the limit assembly and the connection between the limit assembly and the limit hole is released, the valve on one side of the No. 1 three-way valve can be opened. At this time, the high-pressure inert gas can be discharged through the protective gas input pipe. At this time, the valves of the air inlet valve and the exhaust valve are opened. At this time, the high-pressure inert gas can enter the interior of the tank body. At this time, the air inside the tank body can be pressed out and discharged through the exhaust valve until there is no air inside the tank body and the filled protective gas overflows through the exhaust valve. The valve of the air inlet valve is closed. At this time, the inert gas can be filled into the interior of the tank body to complete the protection.

[0011] By utilizing the cooperation between the No. 1 three-way valve and the limit assembly as well as the air inlet valve and the exhaust valve, the device can quickly fill the interior of the tank with high-pressure inert gas after switching to the filling state, and discharge the air inside it. After all the air is discharged, the filling process is carried out, which can ensure that the device will not carry air when injecting benzoyl chloride, and ensure the cleanliness of the interior of the tank, avoid the purity of benzoyl chloride from decreasing, and improve the storage quality.

[0012] As a further technical solution of the present invention, the material delivery assembly includes a first material delivery pipe, the bottom end of the first material delivery pipe is fixedly connected to the second material delivery pipe, the outer side surface of the second material delivery pipe is axially evenly spaced with material delivery holes, and the first material delivery pipe and the first sleeve are movably connected.

[0013] As a further technical solution of the present invention, handles are fixedly installed on the left and right sides of the top of the first material delivery pipe, a limiting component is installed in the middle of the first material delivery pipe, and a rubber sealing plate located inside the second sleeve is fixedly installed at the bottom end of the second material delivery pipe. The diameter of the second material delivery pipe is the same as the inner diameter of the first sleeve, and the inner diameter of the second sleeve is larger than the diameter of the second material delivery pipe.

[0014] When the first delivery pipe is at the highest point, the discharge end of the delivery hole is blocked, and the rubber sealing plate seals the bottom end of the first sleeve. At this time, the device is in an automatic sealing state, and the tank body is not connected to the external environment. When the first delivery pipe is at the lowest point, the second delivery pipe descends to the inside of the second sleeve, and the discharge end of the delivery hole is no longer blocked. Benzoyl chloride can be discharged through the first delivery pipe, the second delivery pipe and the delivery hole, and the benzoyl chloride then enters the inside of the second sleeve, and is input into the interior of the tank body through the feed pipe and the feed port, completing the filling process.

[0015] As a further technical solution of the present invention, the reset assembly includes a fixed sleeve, the bottom end of the fixed sleeve is connected to the middle of the bottom end of the inner cavity of the second sleeve, the internal movably sleeve of the fixed sleeve is connected to a limit plate, the top of the limit plate is fixedly installed with a limit rod, the top of the limit rod passes through the top of the fixed sleeve and is connected to the bottom end of the rubber sealing plate, the outer side surface of the limit rod is movably sleeved with a reset spring, and the upper and lower ends of the reset spring are respectively connected to the top of the inner cavity of the fixed sleeve and the top of the limit plate.

[0016] As a further technical solution of the present invention, when the return spring is in the initial state, the second feed pipe is at the lowest point, and at this time all the feed holes are located inside the second sleeve; when the return spring is in the extreme compression state, the second feed pipe is at the highest point, and all the feed holes are located inside the first sleeve and blocked by the first sleeve, and the top end of the rubber sealing plate contacts the bottom end of the first sleeve and seals the bottom end of the first sleeve.

[0017] After the injection of benzoyl chloride is completed, the input of inert gas into the interior of the limit assembly can be stopped. At this time, both ends of the limit assembly have a reset tendency, but are blocked by the inner wall of the first sleeve. At this time, the handle can be lifted upward to move the first feed pipe upward as a whole, and drive the second feed pipe upward. At this time, the limit rod moves upward accordingly, and the reset spring is compressed. When the reset spring is compressed to the limit position and the rubber sealing plate seals the bottom end of the first sleeve, the limit assembly just corresponds to the limit hole and completes the clamping. At this time, the device returns to the sealed state, completing the rapid sealing process.

[0018] By utilizing the cooperation between the feeding component and the reset component, as well as the cooperation between the limit component and the limit hole, the sealing process can be quickly achieved by simply lifting the feeding component upward. The entire sealing process does not require thread locking and flange connection. The entire process is completed quickly, which can significantly shorten the sealing preparation time of traditional devices, reduce the occurrence of leakage, and improve overall practicality.

[0019] As a further technical solution of the present invention, the limiting assembly includes an air storage pipe, a locking frame is fixedly installed on the outer side of the air storage pipe, the locking frame is connected to the first material delivery pipe, and the top of the air storage pipe near the left and right sides are fixedly connected with air guide holes, and the top of the air storage pipe is provided with a No. 2 three-way valve, the top of the No. 2 three-way valve is connected to the bottom end of the No. 1 three-way valve, and the left and right sides of the No. 2 three-way valve are connected to the two air guide holes.

[0020] As a further technical solution of the present invention, piston plates are movably connected on both sides of the inner cavity of the gas storage tube, and limiting columns are fixedly installed on the relatively far ends of the two piston plates. The side of the limiting column away from the piston plate passes through one side of the gas storage tube and one side of the first feed pipe in sequence, and the outer side surface of the limiting column is movably connected to a limiting spring, and the left and right sides of the limiting spring are connected to one end of the piston plate and one end of the inner cavity of the gas storage tube.

[0021] As a further technical solution of the present invention, when the limit spring is in the initial state and the feeding assembly is at the highest point, the limit column and the limit hole are movably engaged, and when the limit spring is in the stretched state, the limit column and the limit hole are not movably engaged.

[0022] When injecting benzoyl chloride, the external high-pressure inert gas delivery device can be opened, and the high-pressure inert gas can be injected into the interior of the No. 1 three-way valve, and the valve at the bottom end of the No. 1 three-way valve can be opened, while the side valve of the No. 1 three-way valve is kept in a closed state. At this time, the high-pressure gas water enters the interior of the No. 2 three-way valve, and enters the air guide hole and the left and right ends of the air storage tube cavity after being distributed by the No. 2 three-way valve. At this time, the limit spring is stretched by the force, and drives the two limit posts to be relatively close. At this time, the clamping connection between the limit post and the limit hole is released, the limit fixation is released, and the reset component is automatically reset at this time, and drives the feeding component to descend as a whole, and the injection process is completed through the feeding component.

[0023] By utilizing the coordination between the feeding component, the reset component and the limit component, the device only needs to input high-pressure inert gas to automatically release the limit fixation and quickly switch the device to the injection state. The entire process can be completed automatically, which can significantly shorten the preparation time, reduce the waiting time before injection, and improve the overall storage efficiency.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the cooperation between the No. 1 three-way valve and the limit assembly as well as the air inlet valve and the exhaust valve, so that after the device is switched to the filling state, the interior of the tank body can be quickly filled with high-pressure inert gas, and the air inside the tank body can be discharged. After all the air is discharged, the filling process can be carried out, which can ensure that the device does not carry air when injecting benzoyl chloride, and ensure the cleanliness of the interior of the tank body, avoid the purity of benzoyl chloride from decreasing, and improve the storage quality.

[0025] (2) The present invention utilizes the coordination between the feeding component, the reset component and the limit component, so that the device can automatically release the limit fixation and quickly switch the device to the injection state by simply inputting high-pressure inert gas. The entire process can be completed automatically, which can significantly shorten the preparation time, reduce the waiting time before injection, and improve the overall storage efficiency.

[0026] (3) The present invention utilizes the cooperation between the feeding component and the reset component, as well as the cooperation between the limit component and the limit hole, so that the sealing process can be quickly achieved by simply lifting the feeding component upward. The entire sealing process does not require thread locking and flange connection. The entire process is completed quickly, which can significantly shorten the sealing preparation time of traditional devices, reduce the occurrence of leakage, and improve overall practicality.

The middle part of the feeding component 11 is installed with a limit component 13. The left and right sides of the limit component 13 pass through the left and right sides of the feeding component 11. The top of the feeding component 11 is fixedly connected to the No. 1 three-way valve 4. The top of the No. 1 three-way valve 4 is connected to the external high-pressure inert gas delivery pipe, and the bottom end of the No. 1 three-way valve 4 is connected to the top of the limit component 13; When the reset component 12 is subjected to the ultimate pulling force, the feeding component 11 is at the highest point, and the left and right ends of the limit component 13 are movably connected with the limit hole 10. The high-pressure inert gas output by the No. 1 three-way valve 4 acts on the limit component 13 and releases the limit between the limit component 13 and the limit hole 10. The reset component 12 automatically resets and drives the feeding component 11 to move downward, completing the feeding process.

[0031] Before injecting benzoyl chloride, it is necessary to maintain the connection between the top end of the No. 1 three-way valve 4 and the external high-pressure inert gas delivery device, and at the same time, maintain the engagement between the limit assembly 13 and the limit hole 10. At this time, the feeding assembly 11 is at the highest point position, completing the preparation before the injection of benzoyl chloride.

[0032] like Figure 1 and Figure 2 as well as Figure 3 As shown, an air intake valve 2 is fixedly connected to a position near the left side of the top of the tank body 1, and an exhaust valve 3 is fixedly connected to a position near the right side of the top of the tank body 1. The top of the air intake valve 2 is fixedly connected to a protective gas input pipe 5, and the end of the protective gas input pipe 5 away from the air intake valve 2 is connected to one side of the No. 1 three-way valve 4. The air intake valve 2 and the exhaust valve 3 are both one-way valves and the directions of the valves are inward conduction and outward blocking, and outward conduction and inward blocking, respectively, and both are in a normally closed state in the initial state.

[0033] Embodiment: When benzoyl chloride is injected, that is, external high-pressure inert gas is input into the interior of the No. 1 three-way valve 4, that is, after the gas is input into the limit assembly 13 and the connection between the limit assembly 13 and the limit hole 10 is released, the valve on one side of the No. 1 three-way valve 4 can be opened. At this time, the high-pressure inert gas can be exported through the protective gas input pipe 5. At this time, the valves of the air inlet valve 2 and the exhaust valve 3 are opened. At this time, the high-pressure inert gas can enter the interior of the tank body 1. At this time, the air inside the tank body 1 can be squeezed out and exported through the exhaust valve 3 until there is no air inside the tank body 1 and the filled protective gas overflows through the exhaust valve 3. The valve of the air inlet valve 2 is closed. At this time, the inert gas can be filled into the interior of the tank body 1 to complete the protection.

[0034] By utilizing the cooperation between the No. 1 three-way valve 4 and the limit assembly 13 as well as the air inlet valve 2 and the exhaust valve 3, after the device is switched to the filling state, the interior of the tank body 1 can be quickly filled with high-pressure inert gas, and the air inside it can be discharged. After all the air is discharged, the filling process is carried out, which can ensure that the device does not carry air when injecting benzoyl chloride, and ensure the cleanliness of the interior of the tank body 1, avoid the purity of benzoyl chloride from decreasing, and improve the storage quality.

[0035] like Figure 1 and Figure 4 as well as Figure 5 and Figure 6 As shown, the material delivery component 11 includes a first material delivery pipe 111, the bottom end of the first material delivery pipe 111 is fixedly connected to the second material delivery pipe 112, the outer side surface of the second material delivery pipe 112 is axially equidistantly provided with material delivery holes 113, the first material delivery pipe 111 and the first sleeve 7 are movably connected, and handles 115 are fixedly installed on the left and right sides of the top of the first material delivery pipe 111, a limiting component 13 is installed in the middle of the first material delivery pipe 111, and a rubber sealing plate 114 located inside the second sleeve 8 is fixedly installed at the bottom end of the second material delivery pipe 112, the diameter of the second material delivery pipe 112 is the same as the inner diameter of the first sleeve 7, and the inner diameter of the second sleeve 8 is larger than the diameter of the second material delivery pipe 112.

[0036] When the first delivery pipe 111 is at its highest point, the discharge end of the delivery hole 113 is blocked, and the rubber sealing plate 114 seals the bottom end of the first sleeve 7. At this time, the device is in an automatic sealing state, and the tank body 1 is not connected to the external environment. When the first delivery pipe 111 is at its lowest point, the second delivery pipe 112 drops to the inside of the second sleeve 8, and the discharge end of the delivery hole 113 is no longer blocked. Benzoyl chloride can be discharged through the first delivery pipe 111, the second delivery pipe 112 and the delivery hole 113, and the benzoyl chloride then enters the inside of the second sleeve 8, and is input into the inside of the tank body 1 through the feed pipe 9 and the feed port 6, completing the injection process.

[0037] like Figure 4 and Figure 5 As shown, the reset assembly 12 includes a fixed sleeve 121, the bottom end of the fixed sleeve 121 is connected to the middle of the bottom end of the inner cavity of the second sleeve 8, the internal movable sleeve of the fixed sleeve 121 is connected to the limit plate 122, the top of the limit plate 122 is fixedly installed with a limit rod 123, the top of the limit rod 123 passes through the top of the fixed sleeve 121 and is connected to the bottom end of the rubber sealing plate 114, the outer side surface of the limit rod 123 is movably sleeved with a reset spring 124, the upper and lower ends of the reset spring 124 are respectively connected to the top of the inner cavity of the fixed sleeve 121 The end is connected to the top of the limit plate 122. When the return spring 124 is in the initial state, the second material delivery pipe 112 is at the lowest point, and at this time the material delivery holes 113 are all located inside the second sleeve 8. When the return spring 124 is in the extreme compression state, the second material delivery pipe 112 is at the highest point, and the material delivery holes 113 are all located inside the first sleeve 7 and blocked by the first sleeve 7, and the top end of the rubber sealing plate 114 contacts the bottom end of the first sleeve 7 and seals the bottom end of the first sleeve 7.

[0038] After the injection of benzoyl chloride is completed, the input of inert gas into the interior of the limit assembly 13 can be stopped. At this time, both ends of the limit assembly 13 have a reset tendency, but are blocked by the inner wall of the first sleeve 7. At this time, the handle 115 can be lifted upward to make the first feed pipe 111 move upward as a whole, and drive the second feed pipe 112 to move upward. At this time, the limit rod 123 moves upward accordingly, and the reset spring 124 is compressed. When the reset spring 124 is compressed to the limit position and the rubber sealing plate 114 seals the bottom end of the first sleeve 7, the limit assembly 13 just corresponds to the limit hole 10 and completes the clamping. At this time, the device is restored to a sealed state, completing the rapid sealing process.

[0039] By utilizing the cooperation between the feeding component 11 and the reset component 12, as well as the cooperation between the limiting component 13 and the limiting hole 10, the sealing process can be quickly achieved by simply lifting the feeding component 11 upward. The entire sealing process does not require thread locking and flange connection. The entire process is completed quickly, which can significantly shorten the sealing preparation time of traditional devices, reduce the occurrence of leakage, and improve overall practicality.

The outer side surface of the limit column 135 is movably sleeved with a limit spring 136, and the left and right sides of the limit spring 136 are connected to one end of the piston plate 134 and one end of the inner cavity of the gas storage pipe 131. When the limit spring 136 is in the initial state and the material delivery assembly 11 is at the highest point, the limit column 135 is movably engaged with the limit hole 10. When the limit spring 136 is in the stretched state, the limit column 135 is not movably engaged with the limit hole 10.

[0041] Embodiment: When benzoyl chloride is injected, the external high-pressure inert gas delivery device can be opened, and the high-pressure inert gas is injected into the interior of the No. 1 three-way valve 4, and the valve at the bottom end of the No. 1 three-way valve 4 is opened, while the side valve of the No. 1 three-way valve 4 is kept in a closed state. At this time, the high-pressure gas water enters the interior of the No. 2 three-way valve 132, and enters the air guide hole 133 and the left and right ends of the inner cavity of the air storage pipe 131 after being distributed by the No. 2 three-way valve 132. At this time, the limit spring 136 is stretched by the force, and drives the two limit columns 135 to be relatively close. At this time, the clamping connection between the limit column 135 and the limit hole 10 is released, the limit fixation is released, and the reset component 12 is automatically reset at this time, and drives the feeding component 11 to descend as a whole, and the injection process is completed through the feeding component 11.

[0042] By utilizing the coordination between the feeding component 11, the reset component 12 and the limit component 13, the device only needs to input high-pressure inert gas to automatically release the limit fixation and quickly switch the device to the injection state. The entire process can be completed automatically, which can significantly shorten the preparation time, reduce the waiting time before injection, and improve the overall storage efficiency.

[0043] Working principle and usage process: Before the injection of benzoyl chloride, the top of the No. 1 three-way valve 4 must be connected to the external high-pressure inert gas delivery device, and the engagement between the limit assembly 13 and the limit hole 10 must be maintained. At this time, the feeding assembly 11 is at the highest point, completing the preparations before the injection of benzoyl chloride; When benzoyl chloride is injected, the external high-pressure inert gas delivery device can be opened, and the high-pressure inert gas can be injected into the interior of the No. 1 three-way valve 4, and the valve at the bottom end of the No. 1 three-way valve 4 can be opened, while the side valve of the No. 1 three-way valve 4 is kept in a closed state. At this time, the high-pressure gas enters the interior of the No. 2 three-way valve 132, and enters the air guide hole 133 and the left and right ends of the inner cavity of the gas storage pipe 131 after being distributed by the No. 2 three-way valve 132. At this time, the limit spring 136 is stretched by the force, and drives the two limit posts 135 to be relatively close. At this time, the clamping connection between the limit post 135 and the limit hole 10 is released, and the limit fixation is released. At this time, the reset assembly 12 automatically resets, and drives the feeding assembly 11 to descend as a whole, and the injection process is completed through the feeding assembly 11; When the first delivery pipe 111 is at its highest point, the discharge end of the delivery hole 113 is blocked, and the rubber sealing plate 114 seals the bottom end of the first sleeve 7. At this time, the device is in an automatic sealing state, and the tank body 1 is not connected to the external environment. When the first delivery pipe 111 is at its lowest point, the second delivery pipe 112 descends to the inside of the second sleeve 8, and the discharge end of the delivery hole 113 is no longer blocked. Benzoyl chloride can be discharged through the first delivery pipe 111, the second delivery pipe 112, and the delivery hole 113, and then enters the inside of the second sleeve 8 and is input into the interior of the tank body 1 through the feed pipe 9 and the feed port 6; When benzoyl chloride is injected, that is, when external high-pressure inert gas is input into the inside of No. 1 three-way valve 4, after the gas is input to the limit assembly 13 and the clamping connection between the limit assembly 13 and the limit hole 10 is released, the valve on one side of No. 1 three-way valve 4 can be opened, and now the high-pressure inert gas can be exported through the protective gas input pipe 5. At this time, the valves of the air inlet valve 2 and the exhaust valve 3 are opened, and now the high-pressure inert gas can enter the interior of the tank body 1, and now the air inside the tank body 1 can be squeezed out and exported through the exhaust valve 3, until there is no air inside the tank body 1, and the filled protective gas overflows through the exhaust valve 3, the valve of the air inlet valve 2 is closed, and now the inert gas can be filled into the interior of the tank body 1 to complete the protection; After the injection of benzoyl chloride is completed, the input of inert gas into the interior of the limit assembly 13 can be stopped. At this time, both ends of the limit assembly 13 have a reset tendency, but are blocked by the inner wall of the first sleeve 7. At this time, the handle 115 can be lifted upward to make the first feed pipe 111 move upward as a whole, and drive the second feed pipe 112 to move upward. At this time, the limit rod 123 moves upward accordingly, and the reset spring 124 is compressed. When the reset spring 124 is compressed to the limit position and the rubber sealing plate 114 seals the bottom end of the first sleeve 7, the limit assembly 13 just corresponds to the limit hole 10 and completes the clamping. At this time, the device is restored to a sealed state, completing the rapid sealing process.
