Description

Technical Field

[0001] The utility model belongs to the technical field of propionyl chloride production, and particularly relates to a discharging device for propionyl chloride production. Background Technique

[0002] Propionyl chloride is an organic compound, a colorless transparent liquid with a pungent odor, and can be used as a propionylation agent for organic synthesis and an introducing agent for propionic anhydride, a raw material for spices and pharmaceuticals, a raw material for pesticide herbicides, etc. As a production raw material, propionyl chloride often needs to be sampled and detected.

[0003] The Chinese utility model patent with the publication number of CN216918599U discloses a discharging device for propionyl chloride production, including a storage barrel and a support frame outside the storage barrel. A material distribution device is arranged at the bottom of the storage barrel. The material distribution device includes a material distribution barrel and a material distribution pipe. The bottom of the material distribution barrel is provided with a material distribution pipe in an array. A time relay is arranged at the bottom end of the material distribution pipe. A discharging device is arranged at the bottom of the material distribution device. The discharging device includes a discharging disc. A first discharging pipe is arranged at the central position of the discharging disc. Second discharging pipes are arranged in an array on the outer circumference of the first discharging pipe. The volume of the first discharging pipe is three times that of the second discharging pipe. A driving device is connected to the bottom of the discharging device. The material distribution barrel and the material distribution pipe are used for discharging and distributing propionyl chloride. The driving device drives the discharging device to rotate by different angles and then move upward to distribute the propionyl chloride in the first discharging pipe and all the second discharging pipes on the surface of the discharging disc, so as to realize automatic non-contact distribution of different volumes at the same time under the same material distribution device, and increase the discharging adaptability.

[0004] However, there are still some deficiencies in the above-mentioned utility model:

[0005] During the use of the above-mentioned utility model, the discharging pipe is placed in the placement groove to receive the propionyl chloride raw material separated in the material distribution pipe. When the discharging pipe is placed in the placement groove, its edge is clamped on the top of the discharging disc. This requires the operator to push the discharging pipe out of the placement groove from the bottom of the placement groove when taking out the discharging pipe to facilitate the operator to take the discharging pipe. This makes the operator can only take the discharging pipes on the discharging disc one by one, increasing the time for taking all the discharging pipes. In addition, propionyl chloride has a certain volatility. If all the discharging pipes cannot be quickly removed from the discharging disc, it will prolong the volatilization time of propionyl chloride in the air;

[0006] On the other hand, when placing the discharging pipe in the placement groove, a discharging pipe with a size matching that of the placement groove needs to be selected to ensure that the pipe orifice of the discharging pipe can be clamped on the top of the discharging disc, reducing the practicability of the discharging disc.

The top of the general base 1 is fixedly connected with an installation base 4. A lifting assembly 10 is installed on the installation base 4. The lifting assembly 10 is connected with a placing disc 6 through a connecting block 7. A plurality of placing grooves 9 are opened through the top of the placing disc 6. A clamping assembly 11 is installed in each placing groove 9. And directly below each placing groove 9 and on the top of the installation base 4, a fixed base 8 is fixedly connected.

[0031] Specifically, the upper and lower ends of the support column 2 are fixedly connected to the ring top plate 3 and the total base 1 respectively; a sampling tube 13 is placed in each storage slot 9, and the side wall of the sampling tube 13 is clamped by a clamping assembly 11; the lifting assembly 10 can control the storage disc 6 to move in the vertical direction. When the storage disc 6 moves upward, it drives the sampling tube 13 to move upward synchronously and approach the discharging assembly 12, facilitating sampling. When the storage disc 6 moves downward, the fixed base 8 will eject the sampling tube 13 from the storage slot 9, facilitating the operator to take the sampling tube 13; a rubber pad is bonded to the top of the fixed base 8 to protect the bottom of the sampling tube 13.

[0032] Further, the lifting assembly 10 includes threaded rods 101 arranged oppositely left and right. Rotating bases 5 are installed oppositely left and right on the top of the mounting base 4.

[0034] Specifically, the motor 102 controls the connecting rod 103 to drive the bevel gear one 104 to rotate, and the bevel gear two 105 drives the corresponding threaded rod 101 to rotate accordingly, so that the connecting block 7 can drive the storage disc 6 to move in the vertical direction to drive the sampling tube 13 to approach the discharging assembly 12 or approach the fixed base 8.

[0035] Further, the clamping assembly 11 includes elastic telescopic cylinders 112. Mounting grooves 111 are oppositely opened on the side walls of each storage slot 9.

[0038] Specifically, the number of the discharge pipes 122 is consistent with the number of the sampling pipes 13; the electromagnetic valve 123 is set to control the opening and closing of the channel of the discharge pipe 122, so that the propionyl chloride to be sampled in the storage tank 121 drips into the sampling pipe 13 through the discharge pipe 122.

[0039] The working principle and use process of the utility model: After the utility model is installed, the operator inserts the sampling tubes 13 into the storage groove 9 one by one and clamps the side wall of the sampling tube 13 through the elastic telescopic cylinder 112 and the clamping block 113 to maintain the stability of the sampling tube 13 during sampling, and the tube mouth of the sampling tube 13 is clamped on the top of the truncated cone semi-ring block 115;

[0040] The motor 102 controls the connecting rod 103 to drive the bevel gear 1 104 to rotate, and the bevel gear 2 105 drives the corresponding threaded rod 101 to rotate accordingly, so that the connecting block 7 can drive the placement disc 6 and the sampling tube 13 to move upward until the tube mouth of the sampling tube 13 stops near the outlet end of the discharge pipe 122;

[0041] The operator controls the solenoid valve 123 to open the channel of the discharge pipe 122, so that the propionyl chloride to be sampled enters the sampling pipe 13 through the discharge pipe 122 to complete the sampling;

[0042] The motor 102 then controls the placement disc 6 and the sampling tube 13 to move downward, so that the bottom of the sampling tube 13 touches the top of the fixed base 8. At this time, the placement disc 6 moves downward again, and the sampling tube 13 is pushed out of the placement slot 9 with the assistance of the ball 114, which makes it convenient for the operator to quickly take the sampling tube 13 out of the placement slot 9, thereby reducing the volatilization time of propionyl chloride.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
