Description

Technical Field

[0001] The present invention relates to the technical field of oxytetracycline hydrochloride processing, and in particular to an integrated device for separating and drying oxytetracycline hydrochloride particles with an air selection structure. Background Art

[0002] As we all know, oxytetracycline hydrochloride has inhibitory effects on a variety of Gram-positive and Gram-negative bacteria. It is widely used in the veterinary field to treat respiratory infections in livestock. During processing and preparation, after the separation operation of oxytetracycline hydrochloride particles is completed, they are immediately dried efficiently to remove impurities and reduce the moisture content of the particles, and then screen out granular materials that meet specific particle size requirements.

[0003] In the process of oxytetracycline hydrochloride processing, drying equipment is required to reduce the moisture content of the particles. The existing technology has the following problems: generally, hot air drying is adopted, and the separated oxytetracycline hydrochloride particles are placed in a drying chamber. Hot air enters the drying chamber through a special air inlet and fully contacts the particles. The hot air takes away the moisture on the surface of the particles. In this processing process, a material tray is mostly used as a container to dry the particles. During the process, the moisture on the top of the material tray is taken away first, while the drying efficiency at the bottom is low, and the material tray needs to be replaced repeatedly, which is more troublesome in the continuous processing process. In the later stage, the particle size screening is mostly completed by equipment such as a vibrating screen. Although this equipment can screen a large number of particles through the mesh, due to the large number of particles when dumped into the equipment, they stick to each other and when the upper material pushes the lower material to move when put into the equipment, it will reduce the retention time of the material in the vibrating screen, which is easy to cause screening errors.

[0004] Based on the above-mentioned situation, we found that it is difficult to avoid the above problems at the same time when drying oxytetracycline hydrochloride in the existing technology. Therefore, we proposed an integrated equipment for drying oxytetracycline hydrochloride particles after separation, which can limit the material retention rate, dry the particles more evenly during the processing and production process, and control the single sorting amount of particles by air separation after drying, so as to improve the efficiency and screening effect. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the shortcomings of the prior art, the present invention provides an integrated device for drying oxytetracycline hydrochloride particles after separation with an air separation structure, which has the advantages of limiting the material retention rate, drying the particles more evenly during the processing and production process, and controlling the single sorting amount of particles by air separation after drying, so as to improve efficiency and screening effect.

[0007] (II) Technical solution

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: an integrated device for drying oxytetracycline hydrochloride particles after separation with an air selection structure, comprising an inlet cylinder, a drying box is fixedly connected to the bottom of the inlet cylinder, a wind selection cylinder is fixedly connected to the bottom of the drying box, a screening box is provided on the inner side of the inlet cylinder, a drying component is provided on the inner side of the drying box, and an auxiliary component is provided on the inner side of the wind selection cylinder;

[0009] The drying assembly includes a connecting shaft, a movable plate is rotatably connected to the outer side of the connecting shaft, a fixed plate is fixedly connected to the inner side of the drying box, a sealing shell is fixedly connected to the bottom of the movable plate, a hose is fixedly connected to the bottom of the sealing shell, an air duct is fixedly connected to the top of the fixed plate, a flow slot used in conjunction with the air duct is provided on the inner side of the fixed plate, and an air hole used in conjunction with the sealing shell is provided on the inner side of the movable plate;

[0010] The auxiliary component includes a material drop bowl, a hollow frame is fixedly connected to the inner side of the material drop bowl, a wind selection tube is fixedly connected to the inner side of the hollow frame, an air flow channel is fixedly connected to the inner side of the wind selection tube, an outer material tray, a middle material tray and an inner material tray are fixedly connected to the bottom of the wind selection tube, the outer material tray, the middle material tray and the inner material tray are integrally formed, and the bottoms of the outer material tray and the inner material tray are both inclined;

[0011] A control motor is fixedly connected to the rear side of the drying box, and the output end of the control motor passes through the drying box and is fixedly connected to a crankshaft, the bottom of the crankshaft is rotatably connected to a limiting cylinder, the inner side of the limiting cylinder is slidably connected to a wind selection tube, the outer side of the output end of the control motor is fixedly connected to a force frame, the outer side of the force frame is fixedly connected to a collision frame, and the bottom of the moving plate is fixedly connected to a contact frame used in conjunction with the collision frame.

[0012] By adopting the above technical solution, an inlet cylinder is provided for directly inputting the separated granular materials. After passing through the inlet cylinder, the materials will fall into the drying box and directly contact with the moving plate of the internal drying component. The control motor provided at the rear side of the drying box is started, and the control motor can drive the force frame and the collision frame connected thereto to rotate. When the collision frame and the contact frame rotate, a collision will occur, so that the moving plate in contact with the contact frame rotates along the connecting shaft and vibrates. At this time, the materials falling on the moving plate will be vibrated, and the top position of the materials will be limited by the fixed plate to bounce up. Therefore, the wet materials will bounce repeatedly between the moving plate and the fixed plate, and the fan will pass through The air duct blows the air into the interior of the drying component, and enters the material activity space through the circulation slot, and contacts the continuously oscillating material to remove surface moisture, and can also push the material to move from the left side of the moving plate to the right side, so that the material always keeps in motion, and the airflow will also enter the inner side of the sealing shell through the hose, and be discharged from the air hole, and together with the airflow discharged from the circulation slot, it will purge the material, and the mutual purge of the airflow can also avoid the situation where the fixed plate and the moving plate themselves are too wet. After the granular material is dried in the drying box, it will continue to fall into the inside of the air separation cylinder, and the airflow will also be discharged from the gap between the drying box and the air separation cylinder. The granular material will first enter the dropping bowl, and under the restriction of the shape of the dropping bowl, it will approach the air separation tube from the hollow part of the hollow frame and fall down. The airflow will be swept out through the air separation tube and the air flow channel, and the lighter granular material and impurities with a small radius will be blown to a farther distance from the air separation tube and fall down, and fall into the outer material tray for collection. The heavier and larger granular impurities are difficult to be blown away and will fall into the inner material tray. After the material enters the dropping bowl, it will not fall on the surface of the restriction cylinder, but will slide along the restriction cylinder to between the restriction cylinder and the dropping bowl. Since the distance between the dropping bowl and the restriction cylinder is limited, the amount of granular material that falls will also be controlled. When the machine rotates, the crankshaft connected to its output shaft will repeatedly push and pull the limiting cylinder, and make it move vertically repeatedly along the air separation tube to evenly shake off the granular material on the top of the limiting cylinder, and at the same time press the blocking material at the bottom to promote its falling for air separation. During the operation, materials can be continuously added to the inlet cylinder to reduce the trouble of repeatedly replacing the material tray, and the granular material is dried more evenly, and continuous operation can be carried out. After the operation, the dried material can be directly air separated. Since the uniformity of the material falling is controlled, it is not easy for the operation process to fail to achieve the desired effect due to excessive single-time falling of materials.

[0013] The present invention is further configured as follows: the screening box comprises a frame plate, the inner side of the frame plate is clamped with a drop box, the inner side of the drop box is fixedly connected with an upper layer net, and the bottom of the upper layer net is provided with a lower layer net.

[0014] By adopting the above technical solution, by setting a frame piece to cooperate with the drop box, the material will be put into the inlet cylinder when in use, and will slide along the frame piece to the bottom of the drop box, pass through the upper net and the lower net and leak out. The material will be intercepted by the upper net and the lower net when passing through, and the falling speed of the material will be prolonged to prevent too much material from entering the drying box too quickly. Rotating the lower net can stagger the mesh holes between the upper net and the lower net to reduce the space for the material to pass through, further prolong the retention time of the material, and can also filter out larger impurities in the process.

[0015] The present invention is further configured as follows: an extension section is fixedly connected to the bottom of the drop box, a net ring is slidably connected between the extension section and the drop box, the inner side of the net ring is fixedly connected to the lower net, and a hand-held portion is provided at the bottom of the lower net.

[0016] By adopting the above technical solution, by setting an extension ring, the net ring can be easily clamped in the extension section and the inside of the drop box. The net ring is used to install the lower net, and it is convenient to rotate the lower net through the handheld part to stagger the mesh holes between the upper net and the lower net.

[0017] The present invention is further configured as follows: the bottom of the hose is fixedly connected to a bottom pipe, the top of the bottom pipe is fixedly connected to an air duct, a fan is installed on the left side of the drying box, and the output end of the fan is fixedly connected to the air duct.

[0018] By adopting the above technical solution, a bottom pipe is provided to connect the hose and the air duct, and the air flow is uniformly input through the fan, so that the air flow input to the inner side of the fixed plate and the moving plate can be consistent.

[0019] The present invention is further configured as follows: an air pipe is fixedly connected to the top of the air separation tube, and a side of the air pipe away from the air separation tube is fixedly connected to an output end of the fan.

[0020] By adopting the above technical solution and setting an air pipe, it is convenient to connect the output end of the air separation tube and the air fan providing the air flow, so as to achieve the effect of supplying air flow into the interior of the air separation tube for air separation.

[0021] The present invention is further configured as follows: a shielding sheet used in conjunction with the air hole is fixedly connected to the top of the moving plate, and a guide plate used in conjunction with the flow slot is fixedly connected to the bottom of the fixed plate.

[0022] By adopting the above technical solution, a shielding plate is set to prevent granular materials from falling into the air hole and becoming difficult to handle when air flow is injected into the air hole. The set guide plate can prevent the granular materials from being bounced into the top of the fixed plate through the circulation groove, and can also guide the direction of the air flow.

[0023] The present invention is further configured as follows: a bottom frame is fixedly connected to the bottom of the drying box, the inner side of the bottom frame is fixedly connected to the air separation cylinder, and a shielding cover is rotatably connected to the left side of the top of the inlet cylinder.

[0024] By adopting the above technical solution, by setting up a base frame, the structure can be easily installed and placed stably, and the shielding cover can shield the top when no material is put in, preventing external impurities from entering the interior of the drying box.

[0025] The present invention is further configured as follows: a cross bar is fixedly connected to the inner wall of the drying box, and the top of the cross bar is in contact with the bottom of the moving plate.

[0026] By adopting the above technical solution, by setting a cross bar, the top of the moving plate can be easily placed to limit the extreme position of the bottom of the moving plate, and when the moving plate falls, contact with the cross bar will also cause the top material to vibrate.

[0027] The present invention is further configured as follows: a baffle is fixedly connected to the inner wall of the drying box, the left side of the top of the drying box is open, and a matching section is fixedly connected to the bottom of the inlet tube.

[0028] By adopting the above technical solution, by setting the baffle, it is convenient to guide the incoming materials to prevent the materials from falling on the top of the fixed plate and making it difficult to clean them up later.

[0029] The present invention is further configured as follows: the interior of the limiting cylinder is configured to be hollow, the top of the limiting cylinder is configured to be inclined, and the bottom of the limiting cylinder is configured to be arc-shaped.

[0030] By adopting the above technical solution, a hollow limiting cylinder with a lighter weight is set, and the inclined top can facilitate the material to fall along the top of the limiting cylinder to avoid blockage of the structure. The arc-shaped bottom can fit the position of the blanking bowl to assist the material to enter the interior of the air separation cylinder.

[0031] (III) Beneficial effects

[0032] Compared with the prior art, the present invention provides an integrated device for separating and drying oxytetracycline hydrochloride particles with an air selection structure, which has the following beneficial effects:

[0033] The integrated equipment for drying granules after separation of oxytetracycline hydrochloride with an air selection structure is provided with an inlet cylinder for directly inputting the separated granular materials. After passing through the inlet cylinder, the materials will fall into the drying box and directly contact with the moving plate of the internal drying component. The control motor arranged at the rear side of the drying box is started, and the control motor can drive the force frame and the collision frame connected thereto to rotate. When the collision frame and the contact frame rotate, a collision will occur, so that the moving plate in contact with the contact frame rotates along the connecting shaft and vibrates. At this time, the materials falling on the moving plate will be vibrated, and the top position of the materials will be limited by the fixed plate to bounce up to a certain height. The plates bounce repeatedly, and the fan blows the air into the interior of the drying component through the air duct, and enters the material activity space through the circulation slot, and contacts with the continuously oscillating material to remove surface moisture, and can also push the material to move from the left side of the moving plate to the right side, so that the material always keeps in motion, and the airflow will also enter the inner side of the sealing shell through the hose, and be discharged from the air hole, and blow the material together with the airflow discharged from the circulation slot. The mutual blowing of the airflow can also avoid the situation where the fixed plate and the moving plate themselves are too wet. After the granular material is dried in the drying box, it will continue to fall into the interior of the air separation cylinder, and the airflow will also pass between the drying box and the air separation cylinder. The granular materials will first enter the dropping bowl, and under the restriction of the shape of the dropping bowl, they will approach the air separation tube from the hollow part of the hollow frame and fall down. The airflow will sweep out through the air separation tube and the air flow channel, and can blow the lighter granular materials and impurities with a small radius to fall farther away from the air separation tube and fall into the outer material tray for collection. The heavier and larger granular impurities are difficult to be blown away and will fall into the inner material tray. After the materials enter the dropping bowl, they will not fall on the surface of the restriction tube, but will slide along the restriction tube to between the restriction tube and the dropping bowl. Since the distance between the dropping bowl and the restriction tube is limited, the amount of granular materials that fall will also be controlled. When the motor is controlled to rotate, the crankshaft connected to its output shaft will repeatedly push and pull the limiting cylinder, and make it move vertically repeatedly along the air separation tube to evenly shake off the granular material on the top of the limiting cylinder, and at the same time press the blocking material at the bottom to promote its falling for air separation. During the operation, materials can be continuously added to the inlet cylinder to reduce the trouble of repeatedly replacing the material tray, and the granular material is dried more evenly, and continuous operation can be carried out. After the operation, the dried material can also be directly air separated. Since the uniformity of the falling material is controlled, it is not easy for the operation process to fail to achieve the desired effect due to excessive single-time falling of material.

The inner side of the mesh ring 14 is fixedly connected to the lower net 404, and a hand-held portion is provided at the bottom of the lower net 404. By setting the extension ring, the mesh ring 14 can be easily stuck in the extension section 13 and the inside of the drop box 402. The mesh ring 14 is used to install the lower net 404, and it is convenient to rotate the lower net 404 through the hand-held portion so that the mesh holes between the upper net 403 and the lower net 404 are staggered. The bottom of the hose 505 is fixedly connected to the bottom of the hose 505, and the top of the bottom pipe 15 is fixedly connected to the air duct 506. A fan 1 is installed on the left side of the drying box 2. 6. The output end of the fan 16 is fixedly connected to the air duct 506. A bottom tube 15 is provided to connect the hose 505 and the air duct 506, and the airflow is uniformly input through the fan 16, so that the airflow input from the inner side of the fixed plate 503 and the movable plate 502 can be consistent.

The guide plate 20 provided can prevent granular materials from being bounced into the top of the fixed plate 503 through the flow slot, and can also guide the airflow direction. The bottom of the drying box 2 is fixedly connected with a bottom frame 21, and the bottom The inner side of the frame 21 is fixedly connected to the air separation cylinder 3, and the left side of the top of the inlet cylinder 1 is rotatably connected with a shielding cover 22.

[0050] The working principle of this embodiment is as follows: when in use, granular materials are directly put into the inlet tube 1. After passing through the inlet tube 1, the materials will fall into the drying box 2 and directly fall on the top of the moving plate 502. The control motor 7 arranged at the rear side of the drying box 2 is started, and the control motor 7 can drive the force frame 10 and the collision frame 11 connected thereto to rotate. When the collision frame 11 and the contact frame 12 rotate, a collision will occur, so that the moving plate 502 in contact with the contact frame 12 rotates along the connecting shaft 501 and oscillates. At this time, the materials falling on the moving plate 502 will be vibrated, and the top position of the materials will be limited by the fixed plate 503 to the bouncing height. Therefore, the wet materials will bounce repeatedly between the moving plate 502 and the fixed plate 503. The fan 16 blows the airflow into the interior of the drying component 5 through the air duct 506, and also inputs the airflow into the sealing shell 504 through the bottom pipe 15, and enters the material activity space through the flow slot and the air hole, and contacts with the continuously vibrated materials to take away the surface moisture, thereby achieving the drying effect.

[0051] Example 2

[0052] refer to Figure 1-7 , an integrated device for separating and drying oxytetracycline hydrochloride particles with an air selection structure also includes an auxiliary component 6, wherein the auxiliary component 6 includes a blanking bowl 601, a hollow frame 602 is fixedly connected to the inner side of the blanking bowl 601, an air selection tube 603 is fixedly connected to the inner side of the hollow frame 602, an air flow channel 604 is fixedly connected to the inner side of the air selection tube 603, an outer material tray 605, a middle material tray 606 and an inner material tray 607 are fixedly connected to the bottom of the air selection cylinder 3, the outer material tray 605, the middle material tray 606 and the inner material tray 607 are integrally formed, and the bottoms of the outer material tray 605 and the inner material tray 607 are both inclined;

[0053] The rear side of the drying box 2 is fixedly connected with a control motor 7, the output end of the control motor 7 passes through the drying box 2 and is fixedly connected with a crankshaft 8, the bottom of the crankshaft 8 is rotatably connected with a limiting cylinder 9, and the inner side of the limiting cylinder 9 is slidably connected with the air selection tube 603;

[0054] After the granular material is dried in the drying box 2, it will continue to fall into the interior of the air separation cylinder 3, and the air flow will also be discharged from the gap between the drying box 2 and the air separation cylinder 3. The granular material will first enter the drop bowl 601, and under the restriction of the shape of the drop bowl 601, it will approach the air separation tube 603 from the hollow part of the hollow frame 602 and fall. The air flow is swept out through the air separation tube 603 and the air flow channel 604, and the lighter small-radius granular material and impurities can be blown to a farther distance from the air separation tube 603 and fall into the outer material tray 605 for collection. The heavier large-particle impurities are difficult to be blown and will fall into the inner material tray 607. After the material enters the drop bowl 601, it will not fall on the surface of the limiting cylinder 9, and will slide along the limiting cylinder 9 to between the limiting cylinder 9 and the drop bowl 601. The distance between the material bowl 601 and the limiting cylinder 9 is limited, so it will also have a control effect on the amount of particulate material that falls. When the control motor 7 rotates, the crankshaft 8 connected to its output shaft will repeatedly push and pull the limiting cylinder 9, and make it repeatedly move vertically along the air separation tube 603 to evenly shake off the particulate material on the top of the limiting cylinder 9, and at the same time, it can press the blocking material at the bottom to promote its falling for air separation. During the operation, material can be continuously added to the inlet cylinder 1 to reduce the trouble of repeatedly replacing the material tray, and the drying of the particulate material is more uniform, and continuous operation can be carried out. After the operation, the dried material can also be directly air-separated. Since the uniformity of the falling material is controlled, it is not easy for the operation process to fail to achieve the desired effect due to excessive single-time falling of material.

[0055] Among them, the top of the air separation tube 603 is fixedly connected with an air pipe 17, and the side of the air pipe 17 away from the air separation tube 603 is fixedly connected to the output end of the fan 16. By setting the air pipe 17, it is convenient to connect the air separation tube 603 and the output end of the fan 16 that provides airflow, so as to achieve the effect of supplying airflow to the inside of the air separation tube 603 for air separation. The interior of the limiting cylinder 9 is set to be hollow, the top of the limiting cylinder 9 is set to be inclined, and the bottom of the limiting cylinder 9 is set to be arc-shaped. By setting the hollow limiting cylinder 9, the weight is lighter, and the inclined top can facilitate the material to fall along the top of the limiting cylinder 9 to avoid blockage of the structure. The arc-shaped bottom can fit the position of the blanking bowl 601 to assist the material to enter the inside of the air separation cylinder 3.

[0056] Working principle of this embodiment: When in use, the particulate material will continue to fall into the interior of the air separation cylinder 3 after finishing drying in the drying box 2. The particulate material will first enter the drop bowl 601, and under the restriction of the shape of the drop bowl 601, it will fall from the hollow part of the hollow frame 602 close to the air separation tube 603. After the material enters the drop bowl 601, it will not fall on the surface of the restriction cylinder 9, and will slide along the restriction cylinder 9 to between the restriction cylinder 9 and the drop bowl 601. Since the distance between the drop bowl 601 and the restriction cylinder 9 is limited, it will also have a control effect on the amount of particulate material that falls. When the braking motor 7 rotates, the crankshaft 8 connected to its output shaft will repeatedly push and pull the limiting cylinder 9, and make it repeatedly move vertically along the air separation tube 603, so as to evenly shake off the granular material on the top of the limiting cylinder 9, and at the same time, it can press the blocking material at the bottom to promote its falling for air separation. The airflow is swept out through the air separation tube 603 and the air flow channel 604, and the lighter small-radius granular material and impurities can be blown to a farther distance from the air separation tube 603 and fall into the outer material tray 605 for collection. The heavier large-granular impurities that are difficult to be blown will fall into the inner material tray 607 for separate collection and processing.
