Technical Field

[0001] This utility model relates to the field of florfenicol production technology, specifically to a screw feeder for the florfenicol fluorination process. Background Technology

[0002] Florfenicol is a synthetic monofluorinated derivative of thiamphenicol, with the molecular formula C12H14Cl2FNO4S. It is a white or grayish-white crystalline powder, odorless, very slightly soluble in water and chloroform, slightly soluble in glacial acetic acid, and soluble in methanol and ethanol. It is a new veterinary-grade broad-spectrum antibacterial drug, a type of chloramphenicol, successfully developed in the late 1980s. The screw feeder used in the fluorination process of florfenicol is almost identical to common screw feeders.

[0003] Chinese Patent 202420237972.1 proposes a screw feeder for florfenicol powder production. By pushing a moving frame above the feed hopper for intermediate feeding, the material's contact with the outside environment is reduced, and spillage-free transfer feeding is achieved. It also reduces the hassle of intermediate feeding. However, when the transfer tank is filled with raw materials, a lot of raw materials will adhere to the inner wall, which requires manual cleaning and reduces the practicality of the device. Therefore, a screw feeder for the florfenicol fluorination process is proposed to solve the above problems. Utility Model Content

[0006] Furthermore, the striking mechanism includes a rotating rod, a striking block, a dual-axis cylinder, a through hole, and a sliding rod. The rotating rod is rotatably installed on the inner top wall of the moving platform and on both sides of the storage tank. The striking block is fixedly installed on the rear end of the opposite side of the two rotating rods. The dual-axis cylinder is fixedly installed on the inner top wall of the moving platform and between the two rotating rods. The front end of the opposite side of the two rotating rods is provided with a through hole. The output end of the dual-axis cylinder is provided with a sliding rod that extends into the through hole.

[0007] Furthermore, the top of the feeding hopper is provided with a top plate, and a feeding hole is opened at the center of the top of the top plate. U-shaped blocks are fixedly installed at both the front and rear ends of the top of the top plate.

[0008] Furthermore, a discharge pipe is connected to the center of the bottom of the storage hopper, a discharge valve is provided on the outer peripheral wall of the discharge pipe, and a snap-fit ​​block is fixedly installed at the bottom of the outer peripheral wall of the discharge pipe, the snap-fit ​​block matching the U-shaped block.

[0009] Furthermore, L-shaped plates are fixedly installed on the front and left sides of the base, and support legs are fixedly installed at the four corners of the bottom of the moving platform. The support leg on the right side extends into the L-shaped plate, and a fixing bolt with one end penetrating the L-shaped plate and contacting the support leg is threaded to the outside of the L-shaped plate.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] 1.

[0021] In this embodiment, the striking mechanism 5 includes a rotating rod 51, a striking block 52, a dual-axis cylinder 53, a through hole 54, and a sliding rod 55. The rotating rod 51 is rotatably installed on the inner top wall of the moving platform 3 and on both sides of the storage tank 4. The striking block 52 is fixedly installed on the rear end of the opposite side of the two rotating rods 51. The dual-axis cylinder 53 is fixedly installed on the inner top wall of the moving platform 3 and between the two rotating rods 51. The front end of the opposite side of the two rotating rods 51 is provided with a through hole 54.

[0025] Specifically, the position of the feed pipe 41 can be restricted by the snap-fit ​​block 43 and the U-shaped block 72, so that the feed pipe 41 is aligned with the feed hole 73, making it easier for the raw material to fall into the feed hopper 7 and enter the screw conveyor body 2.

[0026] In this embodiment, L-shaped plates 31 are fixedly installed on the front and left sides of the base 1, and support legs are fixedly installed at the four corners of the bottom of the moving platform 3. Casters are provided at the bottom of the support legs, and the right support leg extends into the L-shaped plate 31. A fixing bolt 32 with one end penetrating through the L-shaped plate 31 and in contact with the support leg is threaded to the outside of the L-shaped plate 31.

[0027] Specifically, tighten the fixing bolts 32 to secure the support leg, thus preventing displacement when the storage bucket 4 is struck.

[0028] The working principle of the above embodiments is as follows:

[0029] (1) When in use, first move the screw conveyor body 2 to the feeding position, loosen the fixing bolts 32, move the moving table 3 to the discharge point of the previous process of the raw material, and the storage bucket 4 to hold the raw material. After the raw material is loaded, cover the bucket 6 and move the storage bucket 4 to the top of the screw conveyor body 2.

[0030] (2) Move the feeding tube 41 to drive the snap-fit ​​block 43 into the U-shaped block 72. When the feeding tube 41 is aligned with the feeding hole 73, the right support leg is snapped into the L-shaped plate 31. Tighten the fixing bolt 32 to fix the support leg.

[0031] (3) Open the discharge valve 42, and the raw material in the storage tank 4 can enter the screw conveyor body 2 through the discharge pipe 41. Operate the screw conveyor body 2 to carry out the raw material conveying operation.

[0032] (4) Connect the air outlet of the air compressor to the cylinder 53, operate the cylinder 53 to extend and retract intermittently, the cylinder 53 drives the sliding rod 55 to rotate the rotating rod 51 back and forth, when the rotating rod 51 approaches the storage barrel 4, the striking block 52 can strike its outside, causing the storage barrel 4 to vibrate, thereby shaking off the raw materials attached to the inner wall, without the need for manual cleaning.
