Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical raw material pulverizing and sieving devices, specifically, to a raw material pulverizing and sieving device for compound sulfamethoxypyrimidine sodium. Background Technology

[0002] Compound sulfamethoxypyrimidine sodium is a sulfonamide antibacterial drug that exerts its antibacterial effect by inhibiting bacterial folic acid metabolism. It has inhibitory effects on most Gram-positive and Gram-negative bacteria, such as streptococci, pneumococci, Salmonella, and Escherichia coli, exhibiting good antibacterial activity. During the production of compound sulfamethoxypyrimidine sodium, a pulverizing and sieving device is required to pulverize and sieve the raw material.

[0003] However, existing technologies still have many shortcomings in practical use. For example, the general method for preparing compound sulfamethoxypyrimidine sodium raw materials is to first crush them with a pulverizer and then sieve them with a sieve. This method cannot perform multiple sieves of the compound sulfamethoxypyrimidine sodium raw materials, resulting in insufficient sieve fineness of the raw materials, which affects the quality of subsequent processing and reduces the fineness of the equipment in sieving the compound sulfamethoxypyrimidine sodium raw materials. Utility Model Content

[0004] The purpose of this invention is to provide a raw material crushing and screening device for compound sulfamethoxypyrimidine sodium, which solves the problem in the prior art that the raw material for compound sulfamethoxypyrimidine sodium cannot be screened multiple times, resulting in insufficient screening of the raw material and affecting the quality of subsequent processing.

[0005] This utility model provides the following technical solution: a raw material crushing and screening device for compound sulfamethoxypyrimidine sodium, including a crushing mechanism, a primary screening mechanism for preliminary screening of the compound sulfamethoxypyrimidine sodium raw material is provided at the bottom of the crushing mechanism, a box for receiving the compound sulfamethoxypyrimidine sodium raw material after preliminary screening is provided at the bottom of the primary screening mechanism, and a secondary screening mechanism for secondary screening of the compound sulfamethoxypyrimidine sodium raw material is provided inside the box.

[0006] As a preferred embodiment of the above technical solution, the crushing mechanism includes a tank, and a feed inlet is provided on one side of the top of the tank, with a top cover snapped into the inside of the feed inlet.

[0007] The above technical solution involves pulling the top cover out of the inlet and then feeding the raw material of compound sulfamethoxypyrimidine sodium into the tank through the inlet. Once the feeding is complete, the top cover is re-snatched into the inlet to facilitate sealing the tank.

[0008] As a preferred embodiment of the above technical solution, a crushing motor is fixedly installed on the side of the tank near the feed inlet. The bottom end of the crushing motor is fixedly connected to a first rotating rod via a shaft. The first rotating rod is located inside the tank. Crushing blades are equidistantly sleeved on the surface of the first rotating rod. A mounting frame is fixedly installed at the bottom of the tank. The bottom end of the first rotating rod is rotatably installed inside the mounting frame.

[0009] The above technical solution involves starting a pulverizing motor to drive the first rotating rod to rotate inside the mounting frame. The rotating first rotating rod drives several sets of pulverizing blades to rotate inside the tank. These rotating pulverizing blades pulverize the raw material of compound sulfamethoxypyrimidine sodium, thus facilitating the pulverization of the raw material of compound sulfamethoxypyrimidine sodium.

[0010] As a preferred embodiment of the above technical solution, the primary screening mechanism includes a connecting pipe, the top end of which is connected to the bottom end of the tank. A baffle is slidably installed inside the connecting pipe near the lower side of the tank. Springs are installed on both sides of the inner wall of the connecting pipe through mounting plates. A primary screen is fixedly installed on the top of several sets of springs. The primary screen is located on the lower side of the baffle.

[0011] The above technical solution allows the baffle to be pulled out of the connecting pipe, making it easier to open the connection port between the tank and the connecting pipe. This allows the crushed raw material inside the tank to enter the connecting pipe through the connection port, facilitating the accumulation of the raw material inside the connecting pipe on the surface of the primary screen.

[0012] As a preferred embodiment of the above technical solution, a drive motor is mounted on one side of the outer wall of the connecting pipe via a mounting plate. The output end of the drive motor is fitted with an eccentric wheel via a shaft. The eccentric wheel is located inside the connecting pipe. A striking block is fixedly connected to the end of the eccentric wheel away from the drive motor. The top of the striking block contacts the bottom of the primary screen. A first outlet is opened on the outer wall of the connecting pipe on the side away from the drive motor. A sealing cover is slidably installed on the outer wall of the connecting pipe near the first outlet.

[0013] Using the above technical solution, the drive motor is then started, which drives the eccentric wheel to rotate via the shaft. The rotating eccentric wheel causes the striking block to move up and down at the bottom of the primary screen. The striking block, which moves up and down, strikes the bottom of the primary screen. The striking of the striking block, combined with the elastic force of the spring, causes the primary screen to vibrate. The vibrating primary screen vibrates and screens the raw material accumulated on top of the primary screen, thus achieving the function of preliminary screening of the raw material of compound sulfamethoxypyrimidine sodium. After screening by the primary screen, there are still large particles remaining on the top of the primary screen. By pulling the sealing cover upward, the first outlet can be opened. The larger particles of raw material remaining on the top of the primary screen can be cleaned out through the first outlet and fed back into the tank for further crushing.

[0014] As a preferred embodiment of the above technical solution, the top of the box body is connected to the bottom of the connecting pipe. A second outlet is provided on the outer wall of one end of the box body. Vertical grooves are provided at both ends of the upper side of the second outlet. Vertical sliders are slidably installed inside the two sets of vertical grooves. A partition is fixedly installed between the two sets of vertical sliders. The partition is inserted into the interior of the upper side of the second outlet. Horizontal grooves are provided on both sides of the inner wall of the box body. A collection frame is slidably installed inside the second outlet. The collection frame extends to the bottom of the box body.

[0015] Through the above technical solution, by pulling the partition, the two sets of vertical sliders can move upward inside the vertical chute. The two sets of upward-moving vertical sliders drive the partition to move upward and disengage from the interior of the second outlet, thereby opening the second outlet. By pulling the collection frame out of the box, it is convenient to transfer the raw material of compound sulfamethoxypyrimidine sodium that has been screened inside the collection frame to the next processing procedure.

[0016] As a preferred embodiment of the above technical solution, the secondary screening mechanism includes a secondary screen, which is disposed inside the housing. Horizontal sliders are fixedly installed on both sides of the outer wall of the secondary screen. Several sets of horizontal sliders are slidably installed inside the horizontal slide groove. A connector is fixedly installed at the bottom end of the secondary screen away from the horizontal slide groove.

[0017] With the above technical solution, the raw materials after preliminary screening fall directly into the inside of the box through the connection port between the connecting pipe and the box. After screening by the primary screen, there are still large particles of the raw materials remaining on the top of the primary screen.

[0018] As a preferred embodiment of the above technical solution, a servo motor is mounted on the side of the housing away from the second outlet via a mounting plate. The output end of the servo motor is fixedly connected to a second rotating rod via a shaft. A crank is fitted onto the surface of the second rotating rod. A connecting rod is fixedly connected to the end of the crank away from the second rotating rod. The end of the connecting rod away from the crank is fitted onto the surface of a connecting piece.

[0019] Through the above technical solution, the raw material of compound sulfamethoxypyrimidine sodium that falls into the box accumulates on top of the secondary screen. Then, the servo motor is started, which drives the second rotating rod to rotate via the shaft. The rotating second rotating rod drives the crank to rotate, and the rotating crank drives the connecting rod to rotate. The rotating connecting rod drives the secondary screen to reciprocate inside the box through the connecting part. The sliding of the horizontal slider inside the horizontal groove facilitates the smooth sliding of the secondary screen inside the box. Through the reciprocating movement of the secondary screen, the raw material accumulated on top of the secondary screen is screened a second time, realizing the function of secondary screening of the raw material of compound sulfamethoxypyrimidine sodium.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention utilizes a pulverizing mechanism to pulverize the raw material of compound sulfamethoxypyrimidine sodium, a primary sieving mechanism to perform preliminary sieving of the pulverized raw material, and a secondary sieving mechanism to perform secondary sieving of the preliminary sieving of the raw material. This achieves multiple sieving of the raw material, avoiding the problem of insufficient sieving affecting the quality of subsequent processing, and improving the precision of the device in sieving the raw material.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figures 1-7As shown, this utility model provides a technical solution: a raw material crushing and screening device for compound sulfamethoxypyrimidine sodium, including a crushing mechanism 1. The crushing mechanism 1 includes a tank 101, with a feed inlet 102 on one side of the top of the tank 101. A top cover 103 is snapped into the inside of the feed inlet 102. By pulling the top cover 103 out of the feed inlet 102, the raw material of compound sulfamethoxypyrimidine sodium is fed into the tank 101 through the feed inlet 102. When the feeding is complete, the top cover 103 is snapped back into the feed inlet 102 to facilitate sealing of the tank 101. A crushing motor 104 is fixedly installed on the side of the tank 101 near the feed inlet 102. The bottom end of component 4 is fixedly connected to a first rotating rod 105 via a shaft. The first rotating rod 105 is located inside the tank body 101. Crushing blades 106 are equidistantly sleeved on the surface of the first rotating rod 105. A mounting frame 107 is fixedly installed at the bottom end inside the tank body 101. The bottom end of the first rotating rod 105 is rotatably installed inside the mounting frame 107. By starting the crushing motor 104, the first rotating rod 105 is driven to rotate inside the mounting frame 107. The rotating first rotating rod 105 drives several sets of crushing blades 106 to rotate inside the tank body 101. The several sets of rotating crushing blades 106 crush the raw material of compound sulfamethoxypyrimidine sodium, thereby realizing the function of crushing the raw material of compound sulfamethoxypyrimidine sodium.

[0032] As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the bottom end of the crushing mechanism 1 is equipped with a primary screening mechanism 2 for preliminary screening of compound sulfamethoxypyrimidine sodium raw material. The primary screening mechanism 2 includes a connecting pipe 201, the top end of which is connected to the bottom end of the tank 101. A baffle 202 is slidably installed inside the connecting pipe 201 near the lower side of the tank 101. Springs 203 are installed on both sides of the inner wall of the connecting pipe 201 through mounting plates. A primary screen 204 is fixedly installed on the top of several sets of springs 203. The primary screen 204 is located below the baffle 202. One side of the outer wall of the connecting pipe 201 is connected to a primary screen 204 through mounting plates. A drive motor 205 is mounted on the mounting plate. The output end of the drive motor 205 is mounted on an eccentric wheel 206 via a shaft. The eccentric wheel 206 is located inside the connecting pipe 201. A striking block 207 is fixedly connected to the end of the eccentric wheel 206 away from the drive motor 205. The top of the striking block 207 contacts the bottom of the primary screen 204. A first outlet 208 is opened on the outer wall of the connecting pipe 201 on the side away from the drive motor 205. A sealing cover 209 is slidably installed on the outer wall of the connecting pipe 201 near the first outlet 208. The connecting pipe 201 can be opened by pulling out the baffle 202. The connection port between the tank body 101 and the connecting pipe 201 allows the crushed raw material inside the tank body 101 to enter the interior of the connecting pipe 201 through the connection port. The raw material entering the connecting pipe 201 accumulates on the surface of the primary screen 204. Then, the drive motor 205 is started, which drives the eccentric wheel 206 to rotate via the shaft. The rotating eccentric wheel 206 drives the striking block 207 to move up and down at the bottom of the primary screen 204. The striking block 207, which moves up and down, strikes the bottom of the primary screen 204. The striking of the striking block 207, combined with the elastic force of the spring 203, drives the primary screen 204 to enter the primary screen. The primary screen 204 vibrates and screens the raw material piled on top of the primary screen 204, thus performing preliminary screening of the raw material of compound sulfamethoxypyrimidine sodium. After screening by the primary screen 204, there are still large particles remaining on the top of the primary screen 204. By pulling the sealing cover 209 upward, the first outlet 208 can be opened. The larger particles of raw material remaining on the top of the primary screen 204 can be cleaned out through the first outlet 208 and fed back into the tank 101 for further crushing.

[0033] As one implementation method in this embodiment, such as Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the bottom of the primary screening mechanism 2 is equipped with a box 3 for receiving the pre-screened compound sulfamethoxypyrimidine sodium raw material. The top of the box 3 is connected to the bottom of the connecting pipe 201. A second outlet 301 is opened on the outer wall of one end of the box 3. Vertical grooves 302 are opened at both ends of the upper side of the second outlet 301. Vertical sliders 303 are slidably installed inside the two sets of vertical grooves 302. A partition 304 is fixedly installed between the two sets of vertical sliders 303. The partition 304 is inserted into the upper side of the second outlet 301. Horizontal grooves 305 are opened on both sides of the inner wall of the box 3. A collection frame 306 is slidably installed inside the second outlet 301. The collection frame 306 extends to the bottom of the box 3. After the pre-screening... After separation, the raw material falls directly into the interior of the box 3 through the connection port of the connecting pipe 201 and the box 3. Pulling the partition 304 allows the two sets of vertical sliders 303 to move upward inside the vertical chute 302. The two sets of upward-moving vertical sliders 303 drive the partition 304 to move upward and detach from the interior of the second outlet 301, thereby opening the second outlet 301. This allows workers to clean out a portion of the raw material particles remaining at the top of the secondary screen 401. The cleaned raw material particles are then fed back into the interior of the tank 101 for further crushing. By pulling the collection frame 306 out of the interior of the box 3, the raw material of compound sulfamethoxypyrimidine sodium that has been screened inside the collection frame 306 can be transferred to the next processing procedure.

[0034] As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 7As shown, the interior of the housing 3 is equipped with a secondary screening mechanism 4 for secondary screening of compound sulfamethoxypyrimidine sodium raw material. The secondary screening mechanism 4 includes a secondary screen 401, which is disposed inside the housing 3. Horizontal sliders 402 are fixedly installed on both sides of the outer wall of the secondary screen 401. Several sets of horizontal sliders 402 are slidably installed inside horizontal grooves 305. A connector 403 is fixedly installed at the bottom end of the secondary screen 401 away from the horizontal grooves 305. A servo motor 404 is mounted on the side of the housing 3 away from the second outlet 301 via a mounting plate. The output end of the servo motor 404 is fixedly connected to a second rotating rod 405 via a shaft. A crank 406 is fitted onto the surface of the second rotating rod 405. A connecting rod 407 is fixedly connected to the end of the crank 406 away from the second rotating rod 405. The end of the connecting rod 407 away from the crank 406 is fitted with a connecting rod 407. The raw material of compound sulfamethoxypyrimidine sodium, which falls into the housing 3, is mounted on the surface of the connector 403 and accumulates on top of the secondary screen 401. Then, the servo motor 404 is started, which drives the second rotating rod 405 to rotate via the shaft. The rotating second rotating rod 405 drives the crank 406 to rotate, and the rotating crank 406 drives the connecting rod 407 to rotate. The rotating connecting rod 407 drives the secondary screen 401 to reciprocate inside the housing 3 via the connector 403. The sliding of the transverse slider 402 inside the transverse groove 305 facilitates the smooth sliding of the secondary screen 401 inside the housing 3. The reciprocating movement of the secondary screen 401 performs secondary screening of the raw material accumulated on top of the secondary screen 401. The screened raw material falls into the collection frame 306, realizing the function of secondary screening of the raw material of compound sulfamethoxypyrimidine sodium.

[0035] It should be noted that the mesh size of the secondary screen 401 is smaller than that of the primary screen 204.

[0036] Working principle: In use, first pull the top cover 103 out of the feed inlet 102, then feed the raw material of compound sulfamethoxypyrimidine sodium into the tank 101 through the feed inlet 102. When the raw material feeding is completed, re-snap the top cover 103 into the feed inlet 102 to facilitate sealing of the tank 101. Then, start the crushing motor 104 to drive the first rotating rod 105 to rotate inside the mounting frame 107. The rotating first rotating rod 105 drives several sets of crushing blades 106 to rotate inside the tank 101. The several sets of rotating crushing blades 106 crush the raw material of compound sulfamethoxypyrimidine sodium, realizing the function of crushing the raw material of compound sulfamethoxypyrimidine sodium.

[0037] When the raw material for compound sulfamethoxypyrimidine sodium is pulverized, the baffle 202 is pulled out of the connecting pipe 201 to facilitate opening the connection port between the tank 101 and the connecting pipe 201. This allows the pulverized raw material inside the tank 101 to enter the connecting pipe 201 through the connection port. The raw material inside the connecting pipe 201 accumulates on the surface of the primary screen 204. Then, the drive motor 205 is started, which drives the eccentric wheel 206 to rotate via the shaft. The rotating eccentric wheel 206 drives the striking block 207 to move up and down at the bottom of the primary screen 204. The moving striking block 207 strikes the bottom of the primary screen 204. The striking of the striking block 207, combined with the elastic force of the spring 203, drives the primary screen 204 to rotate. 4. Vibration is performed. The vibrating primary screen 204 vibrates and screens the raw material piled on top of the primary screen 204, realizing the function of preliminary screening of the raw material of compound sulfamethoxypyrimidine sodium. After preliminary screening, the raw material falls directly into the interior of the box 3 through the connection port of the connecting pipe 201. After screening by the primary screen 204, there are still large particles remaining on the top of the primary screen 204. By pulling the sealing cover 209 upward, the first outlet 208 can be opened. The larger particles of raw material remaining on the top of the primary screen 204 are cleaned out through the first outlet 208 and the larger particles of raw material are put back into the tank 101 for further crushing.

[0038] The raw material of compound sulfamethoxypyrimidine sodium, which falls into the box 3, accumulates on top of the secondary screen 401. Then, the servo motor 404 is started, which drives the second rotating rod 405 to rotate through the shaft. The rotating second rotating rod 405 drives the crank 406 to rotate, and the rotating crank 406 drives the connecting rod 407 to rotate. The rotating connecting rod 407 drives the secondary screen 401 to reciprocate inside the box 3 through the connecting piece 403. The sliding of the horizontal slider 402 inside the horizontal slide groove 305 facilitates the smooth sliding of the secondary screen 401 inside the box 3. The reciprocating movement of the secondary screen 401 performs secondary screening of the raw material accumulated on top of the secondary screen 401. The screened raw material falls into the collection frame 306, realizing the function of secondary screening of the raw material of compound sulfamethoxypyrimidine sodium.

[0039] After screening, some raw material particles remain on the top of the secondary screen 401. By pulling the partition 304, the two sets of vertical sliders 303 move upward inside the vertical chute 302. The two sets of upward-moving vertical sliders 303 drive the partition 304 to move upward and exit from the interior of the second outlet 301, thereby opening the second outlet 301. This allows workers to clean out the remaining raw material particles on the top of the secondary screen 401. The cleaned raw material particles are then fed back into the tank 101 for further crushing. By pulling the collection frame 306 out of the box 3, the raw material of compound sulfamethoxypyrimidine sodium that has been screened inside the collection frame 306 can be transferred to the next processing step.

[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
