Description

Technical Field

[0001] This utility model relates to a screening device for the production of florfenicol powder, belonging to the field of florfenicol powder screening technology. Background Technology

[0002] Florfenicol powder is a veterinary antibiotic primarily used to treat bacterial infections in poultry, pigs, and other animals. Its chemical name is florfenicol, belonging to the amide alcohol class of antibiotics. Its mechanism of action is similar to chloramphenicol, inhibiting bacterial growth by interfering with bacterial protein synthesis. In the production of florfenicol powder, screening equipment is crucial for ensuring product quality and particle size uniformity. This equipment is mainly responsible for separating the pulverized florfenicol raw material powder according to a specific particle size range, removing excessively large particles and any impurities.

[0003] Chinese utility model patent CN218963241U discloses a screening device for the production of florfenicol powder. The cleaning mechanism can clean the florfenicol powder on the top of the screen, reducing the possibility of florfenicol powder residue on the top of the screen causing blockage. By setting an observation window, the staff can see the florfenicol powder stored inside the silo, reducing the accumulation of florfenicol powder on the top of the screen after the silo is full.

[0004] However, the above-mentioned patent has the following inconveniences in actual production and application: First, the cleaning mechanism is complex and affects the screening work during the cleaning process. After the florfenicol powder falls onto the stationary filter screen, it cannot flow and is not easy to pass through the mesh, resulting in poor screening effect; Second, it is not convenient to collect larger particles and the screened finished product separately.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a screening device for the production of florfenicol powder, which can prevent clogging of the sieve holes during the screening process, improve the screening effect, and facilitate the separate collection of larger particles and the screened finished product.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A screening device for producing florfenicol powder includes a tank, with a sieve plate inclined inside the tank. An upper connecting rod is hinged to both sides of the front end of the sieve plate, and a lower connecting rod is hinged to both sides of the rear end of the sieve plate.

[0009] The upper end of the upper connecting rod is hinged to the top wall of the tank. A platform support plate is provided directly above the rear end of the screen plate inside the tank. The upper end of the lower connecting rod is hinged to the lower surface of the platform support plate.

[0010] A reciprocating drive device is provided on one side of the screen plate; a storage bucket is provided directly below the rear end of the screen plate; and a guide plate is provided inclined on the lower side of the screen plate.

[0011] Furthermore, the reciprocating drive device includes a drive motor mounted on the outer wall of the tank, a rotating wheel mounted on the drive shaft of the drive motor, a pull rod connected between the rotating wheel and the screen plate, one end of the pull rod being mounted on the edge of the rotating wheel, and the other end of the pull rod being hinged to one side of the screen plate.

[0012] Furthermore, the sieve plate is provided with sieve holes, and side plates are provided on both sides of the sieve plate. An inclined front baffle is provided at the upper front end of the sieve plate.

[0013] Furthermore, the upper surface of the sieve plate is provided with multiple rows of material distribution baffles from front to back, and each material distribution baffle is composed of multiple spaced-apart material blocking pieces.

[0014] Furthermore, a conveying auger is horizontally provided on the top of the tank body, a feed hopper is provided at the top of the input end of the conveying auger, a feed pipe is provided at the bottom of the output end of the conveying auger, and the outlet of the feed pipe is directly opposite the front end of the screen plate.

[0015] Furthermore, the outer wall of the tank is provided with a holding groove, and the storage bucket is placed in the space formed by the holding groove and the outer wall of the tank.

[0016] Furthermore, the bottom of the container is hinged to the outer wall of the tank, and a locking buckle is provided at the upper end of the outer wall of the container, so that the container is fixed to the outer wall of the tank by the locking buckle.

[0017] Furthermore, the two sides of the guide plate are folded upward at a certain angle, so that the cross-section of the guide plate is groove-shaped, and a feeding vibrator is provided at the bottom of the guide plate.

[0018] Furthermore, the outer wall of the tank is provided with a discharge port, which corresponds to the outlet at the lower end of the guide plate.

[0019] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0020] The feed pipe at the bottom of the conveying auger discharges material to the front end of the screen plate, and the reciprocating drive pulls one side of the screen plate to make it swing back and forth; this achieves a good screening effect, and the shaking can prevent the screen holes from clogging.

[0021] Large particles and impurities fall into the storage bin, while the finished florfenicol powder that passes through the sieve falls onto the guide plate and flows out automatically along the guide plate, thus automatically separating the large particles from the finished florfenicol powder.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0029] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0030] like Figure 1-2 As shown, this utility model provides a screening device for the production of florfenicol powder, including a tank 1, a sieve plate 8 is inclinedly arranged inside the tank 1, an upper connecting rod 6 is hinged to both sides of the front end of the sieve plate 8, and a lower connecting rod 7 is hinged to both sides of the rear end of the sieve plate 8.

[0031] The upper end of the upper connecting rod 6 is hinged to the top wall of the tank body 1. A platform support plate 5 is provided directly above the rear end of the screen plate 8 inside the tank body 1. The upper end of the lower connecting rod 7 is hinged to the lower surface of the platform support plate 5.

[0032] A reciprocating drive device is provided on one side of the sieve plate 8; a storage tank 11 is provided directly below the rear end of the sieve plate 8; and a guide plate 9 is inclined on the lower side of the sieve plate 8.

[0033] like Figure 2The reciprocating drive device includes a drive motor 16 disposed on the outer wall of the tank body 1. A rotating wheel 15 is mounted on the drive shaft of the drive motor 16. A pull rod 14 is connected between the rotating wheel 15 and the screen plate 8. One end of the pull rod 14 is installed at the edge of the rotating wheel 15, and the other end of the pull rod 14 is hinged to one side of the screen plate 8.

[0034] The sieve plate 8 is provided with sieve holes, and side plates 801 are provided on both sides of the sieve plate 8. The upper front end of the sieve plate 8 is provided with an inclined front baffle 802.

[0035] like Figure 3 The upper surface of the sieve plate 8 is provided with multiple rows of uniform material baffles 803 from front to back, and each uniform material baffle 803 is composed of multiple spaced-apart baffles. Florfenicol powder is sprinkled into the sieve plate 8 from the front end. Under the blocking effect of the multiple rows of uniform material baffles 803, the powder can flow evenly through the sieve plate 8, while also blocking the downward flow velocity of the powder and enhancing the screening effect.

[0036] The top of the tank 1 is horizontally equipped with a conveying auger 2. The top of the input end of the conveying auger 2 is equipped with a feed hopper 3, and the bottom of the output end of the conveying auger 2 is equipped with a feed pipe 4. The outlet of the feed pipe 4 is directly opposite the front end of the screen plate 8. The spiral blades of the conveying auger 2 play a role in crushing the powder during the material conveying process, preventing the powder from agglomerating.

[0037] The outer wall of the tank 1 is provided with a holding groove 10, and the storage bucket 11 is placed in the space formed by the holding groove 10 and the outer wall of the tank 1.

[0038] The bottom of the holding trough 10 is hinged to the outer wall of the tank body 1. A locking buckle 12 is provided at the upper end of the outer wall of the holding trough 10, which fixes the holding trough 10 to the outer wall of the tank body 1.
