Description

Technical Field

[0001] The present application relates to the technical field of veterinary drug granule drying, and specifically discloses veterinary drug granule drying equipment. Background Art

[0002] Veterinary drugs refer to substances used to prevent, treat and diagnose animal diseases or purposefully regulate animal physiological functions. In the field of veterinary drug production and preparation technology, there are many granular drugs in veterinary drugs. The processed veterinary drugs generally have a high temperature, and there is still a certain amount of moisture left on the drugs. Since the granular drugs need to be packaged in the later stage, if the veterinary drug particles are not dried but directly packaged and stored, the veterinary drug particles will deteriorate faster, thereby reducing the effect of the veterinary drugs. Therefore, the processed veterinary drug particles need to be dried through drying equipment;

[0003] At present, the drying technology of veterinary drug granules usually adopts stirring drying or clamping and drying the veterinary drug granules using a heating plate with sieve holes, both of which are to solve the problem of uneven drying;

[0004] However, the above-mentioned means or methods to solve the uneven drying are not effective overall. Taking stirring drying as an example, for veterinary drug granules, there is always a long-term contact surface that is heated, and the heating of this long-term contact surface and the non-long-term contact surface is not uniform enough. For the heating plate with sieve holes, the principle of the heating plate with sieve holes is nothing more than clamping the particles for heating. The clamping point position and the non-clamping point position are also not uniform enough. Therefore, the inventor proposed a veterinary drug granule drying device in view of this. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that when traditional veterinary drug granules are dried, there is always a contact surface between the veterinary drug granules, and thus the drying is not sufficient due to the contact surface.

[0006] In order to achieve the above object, the present invention provides the following basic scheme:

[0007] Veterinary drug granule drying equipment comprises a base, a mounting cylinder arranged on the base, an extension cylinder detachably connected to the mounting cylinder, and an end cover detachably connected to the extension cylinder;

[0008] The end cover is provided with a plurality of feed ports penetrating the end cover, a hot air generating assembly is provided inside the end cover, the hot air of the hot air generating assembly is directed toward the extension tube, a trampoline assembly for suspending veterinary drug particles is provided inside the extension tube, and a stirring assembly for dispersing veterinary drug particles is provided on the end cover in coordination with the trampoline assembly;

[0009] Trampoline assembly: a trampoline body slidably connected to the inner wall of the extension tube, a traction assembly arranged at the bottom of the installation tube for pulling and placing the trampoline body, and a return spring arranged at the sliding connection between the trampoline body and the inner wall of the long tube;

[0010] The hot air generated by the hot air generating assembly has an action range covering the upper section of the extension tube, and the reset position of the trampoline body is at the lower section of the extension tube.

[0011] The principles and effects of this basic solution are:

[0012] 1. Compared with the prior art, the present device has a simple structure and an ingenious design. The present device rationally utilizes the characteristic of veterinary drug particles having a stable shape and is provided with a trampoline assembly. The trampoline assembly is used to give the veterinary drug particles an initial upward velocity, thereby making the veterinary drug particles move upward, that is, the veterinary drug particles overcome their own gravity to do work. In this process, the veterinary drug particles are in a suspended state, and the veterinary drug particles in the suspended state are used to achieve non-contact drying of the veterinary drug particles, thereby eliminating the contact surface of the veterinary drug particles. This ultimately solves the problem that when traditional veterinary drug particles are dried, there is always a contact surface of the veterinary drug particles, and the drying is not sufficient due to the contact surface.

[0013] 2. Compared with the prior art, the core point of this device is that it simulates the traditional manual use of a dustpan to throw the veterinary medicine particles upward, so that the veterinary medicine particles briefly enter a suspended state, and the device is provided with a hot air generating component, which can limit the hot air power and hot air range of the hot air generating component, thereby realizing that the veterinary medicine particles enter the hot air range for a drying state. When the upward acceleration of the hot air range is zero, the hot air range is away from the hot air range due to the influence of gravity, and then leaves the drying state. For the veterinary medicine particles, the entire state is an alternating state of cold-hot-cold-hot-cold. Although this drying state does not have good drying efficiency for some veterinary medicine particles that need to be dried, because it is an alternating state of cold-hot, however, because it is an alternating state of cold-hot-cold-hot-cold, it is more beneficial for some veterinary medicine particles that are more sensitive to drying temperature, because the failure of veterinary medicine particles due to excessive drying will be greatly reduced.

[0014] 3. Compared with the prior art, this device simulates the traditional manual use of a dustpan to throw the veterinary drug particles upwards, and is equipped with a hot air generating component to achieve suspended drying. When the veterinary drug particles are thrown upwards, there is a phenomenon of veterinary drug particles sticking together. If the veterinary drug particles with the veterinary drug particle phenomenon come into contact with the hot air range, the hot air cannot fully act on the veterinary drug particles, and then there is a problem of uneven drying. Therefore, this device is equipped with a stirring component, which can not only reduce the phenomenon of veterinary drug particles sticking together, but also act on the feed port, so that the veterinary drug particles falling through the feed port can be more dispersed.

[0015] 4. Compared with the prior art, the present device is provided with a trampoline assembly to realize that the veterinary drug particles are thrown upward. The veterinary drug particles can be thrown upward only after the trampoline assembly is compressed. Before the trampoline assembly is compressed, the trampoline assembly is used in conjunction with the stirring assembly. After the stirring assembly is started, there will be slight mechanical vibrations. After the stirring assembly is connected to the trampoline assembly, the slight mechanical vibrations will be transmitted to the trampoline assembly, so that the veterinary drug particles falling on the trampoline assembly through the feed port can be dispersed as much as possible, which is conducive to the suspended drying of the veterinary drug particles thrown upward after the trampoline assembly is compressed.

[0034] Implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown:

[0035] Veterinary drug granule drying equipment comprises a base, a mounting cylinder arranged on the base, an extension cylinder detachably connected to the mounting cylinder, and an end cover detachably connected to the extension cylinder;

[0036] On the whole:

[0037] The mounting tube is fixedly connected to the base, the outer diameter of the base is larger than the outer diameter of the mounting tube, fixing holes are opened around the base, one end of the extension tube is threadedly connected to the end cover, and the other end of the extension tube is threadedly connected to the mounting tube, the bottom of the end cover is provided with a first external thread, and the bottom of the extension tube is provided with a second external thread.

[0038] Specifically: a fixing hole is provided for the fixed installation of the device to improve the stability of the device, and the separable state between the installation cylinder, the end cover and the extension cylinder is realized through the first external thread and the second external thread. Since the device is a mechanical device, there is maintenance or daily maintenance, etc., and the threaded connection method can facilitate the maintenance or daily maintenance of the staff.

[0039] The end cover is provided with a plurality of feed ports penetrating the end cover, a hot air generating assembly is provided inside the end cover, the hot air of the hot air generating assembly is directed toward the extension tube, a trampoline assembly for suspending veterinary drug particles is provided inside the extension tube, and a stirring assembly for dispersing veterinary drug particles is provided on the end cover in coordination with the trampoline assembly;

[0040] Trampoline assembly: a trampoline body slidably connected to the inner wall of the extension tube, a traction assembly arranged at the bottom of the installation tube for pulling and placing the trampoline body, and a return spring arranged at the sliding connection between the trampoline body and the inner wall of the long tube;

[0041] The hot air generated by the hot air generating assembly has an action range covering the upper section of the extension tube, and the reset position of the trampoline body is at the lower section of the extension tube.

[0042] About the trampoline:

[0043] First, the trampoline body includes a frame, sliding blocks arranged around the frame, an elastic pad arranged inside the frame, a front connecting block and a rear connecting block passing through and fixed to the elastic pad, a sliding groove is opened on the inner wall of the extension tube at the position corresponding to the sliding block, the return spring is installed at the bottom of the sliding groove, the traction assembly includes a traction motor, a traction wheel coaxially connected to the traction motor, and a traction rope wound around the traction wheel, a pull ring is provided at one end of the traction rope, the pull ring is fixed to the rear connecting block, and the other end of the traction rope is connected to the traction wheel.

[0044] Specifically: the traction motor works to realize the winding of the traction rope, and pulls the trampoline body downward. When the trampoline body is pulled downward, the reset spring begins to compress. As long as the traction motor stops working, the trampoline body will quickly move upward under the action of the reset spring, thereby realizing the subsequent suspended drying of veterinary drug particles.

[0045] Regarding the trampoline body: it also includes an auxiliary component for assisting the pulling and placing of the trampoline component, the auxiliary component includes a plurality of mounting points arranged on the elastic pad, a plurality of auxiliary ropes and a plurality of fixed points arranged on the inner bottom of the mounting tube, one end of the auxiliary rope is fixedly connected to the mounting point, and the other end of the auxiliary rope is fixedly connected to the fixed point on the inner bottom of the mounting tube, the length of the auxiliary rope is greater than the length of the traction rope, the outer diameter of the frame is equal to the inner diameter of the extension tube, and the mounting points are evenly distributed on the elastic pad.

[0046] Specifically: Since the trampoline body will move upward rapidly, in order to achieve the stability of the trampoline body, an auxiliary rope is set, the length of the auxiliary rope is much longer than the length of the traction rope, and the outer diameter of the frame is equal to the inner diameter of the extension tube to prevent the veterinary drug particles from falling and no longer being affected by the trampoline body;

[0047] The end cover includes an upper end body and a lower end body, the feed port passes through the upper end body and the lower end body, an extrusion cover plate is provided at the connection between the feed port and the lower end body, and the extrusion cover plate is provided with a plurality of compression springs. When the compression springs are in an initial state, the extrusion cover plate seals the feed port on the lower end body, and the feed port on the upper end body is flush with the upper surface of the upper end body.

[0048] Specifically: when the feed port no longer discharges material, the compression spring no longer stretches, and the compression spring resets. After the compression spring resets, the extrusion cover plate can seal the feed port on the lower end body. Therefore, for the extrusion cover plate, the inner side surface of the extrusion cover plate needs to be an inclined surface.

[0049] The hot air generating assembly includes a plurality of through cavities installed through the upper end body and the lower end body, an air outlet machine arranged outside the upper end body and a plurality of electric heating resistance wire groups, the through cavity includes an air outlet duct and a heating duct, the heating duct is located in the upper end body, the air outlet duct is located in the lower end body, the inner walls of the air outlet duct and the heating duct are both inclined surfaces, the electric heating resistance wire group is arranged in the heating duct, and the air outlet of the air outlet machine is connected to the heating duct.

[0050] Specifically: the air outlet machine exhausts air, starts the electric heating resistance wire group, and then generates hot air, and the hot air is used to achieve drying. When the device is used normally, an air outlet hole is provided at the bottom of the extension tube, and the air outlet hole is used to ensure the internal and external air pressure balance of the device.

[0051] The stirring assembly includes a sleeve installed through the upper end body and the lower end body, an output motor arranged on the sleeve located outside the upper end body, a stirring shaft coaxially connected to the output motor and a contact block arranged at the free end of the stirring shaft, the stirring shaft is symmetrically fixed with stirring rods on both sides close to the contact block, when the return spring is in an uncompressed state, the contact block contacts the front connecting block, the stirring shaft passes through the sleeve located outside the lower end body and a rotating bearing is provided at the connection with the sleeve, and a rubber pad is provided at the free end of the contact block.

[0052] After the stirring component is started, there will be slight mechanical vibration. After the stirring component is connected to the trampoline component, the slight mechanical vibration will be transmitted to the trampoline component, so that the veterinary drug particles falling on the trampoline component through the feed port can be dispersed as much as possible, which is conducive to the suspended drying of the veterinary drug particles after the trampoline component is compressed.

[0053] The extension tube includes a cold section and a hot section. The hot section is the action range of the hot air generating component, and the action range acts on the extension tube to form a hot section. The cold section is the invalid action range of the hot air generating component. The cold section and the hot section are welded, and non-metallic parts are provided at the welding point between the cold section and the hot section.

[0054] Specifically: a cold section and a hot section are used to distinguish the scope of action of hot air, and non-metallic parts are provided to reduce the impact of metal heat transfer. In order to ensure the drying effect, the initial position of the trampoline assembly is located in the cold section.

[0055] Specific implementation process:

[0056] In the first step, the veterinary drug particles fall from the feed port onto the elastic pad. When no more veterinary drug particles fall from the feed port, the extrusion cover cannot be opened due to the action of the compression spring. At this time, the outlet position of the feed port is in a closed state. Then the output motor is started to rotate the stirring rod. The stirring rod causes the veterinary drug particles falling on the elastic pad to begin to disperse, thereby reducing the accumulation and sticking of veterinary drug particles.

[0057] In the second step, the output motor is then turned off; the traction motor is started to move the elastic pad downward, the reset spring is compressed, and the trampoline assembly is now located in the cold section, and then the hot air generating assembly is started to generate hot air. For the extension tube, the extension tube forms a cold section and a hot section, and the hot air has an action range of the hot section. Then the traction motor no longer does work, the force restricting the reset spring disappears, the reset spring begins to reset, and the elastic pad begins to move upward to the initial state of the reset spring. At this time, the contact block contacts the front connection block, that is, the stirring rod in the first step causes the veterinary drug particles falling on the elastic pad to begin to disperse.

[0058] In the third step, the elastic pad still makes a quick emergency stop in the cold section at this time, but for the veterinary drug particles, due to inertia, they continue to move upward and move to the range of action of the hot air generating component, that is, the hot section, and the suspended drying begins. For the veterinary drug particles, the kinetic potential energy begins to decrease, and the direction of movement is opposite to the action direction of the hot air generating component. Therefore, the veterinary drug particles cannot enter the end cover. Even if a small amount of veterinary drug particles enter the end cover, the veterinary drug particles cannot stay in the end cover because the interior of the end cover is all designed with inclined surfaces; when the kinetic potential energy drops to zero, the action of the hot air generating component will re-act on the veterinary drug particles to the elastic pad, that is, the cold section. For the veterinary drug particles, it is a drying state of alternating cold-hot-cold-hot-cold, and it is suspended drying. In addition, in order to further reduce the sticking phenomenon of the veterinary drug particles, after a cold-heat cycle is completed, the output motor needs to be restarted so that the stirring rod acts on the veterinary drug particles that have been dried once again, thereby reducing the sticking phenomenon of the veterinary drug particles again.

[0059] The device solves the problem that when drying traditional veterinary drug particles, there is always a contact surface between the veterinary drug particles, which leads to insufficient drying.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
