Description

Technical Field

[0001] This utility model relates to the field of tobacco drying equipment technology, and in particular to a feeding device for a tobacco power plant dryer. Background Technology

[0002] The tobacco power workshop is an important auxiliary workshop in the tobacco production workshop, mainly providing energy supply for the entire workshop, such as cold water, compressed air, steam, negative pressure, etc. When providing compressed air for the entire workshop, a corresponding adsorption dryer is usually connected downstream of the air compressor to remove moisture from the compressed air generated by the air compressor. The adsorption dryer usually contains an adsorbent, which uses its properties to capture and absorb moisture in the compressed air. However, the adsorption capacity of the adsorbent is limited. When the adsorption capacity reaches its limit, the moisture in the compressed air cannot be removed, and the adsorbent in the adsorption dryer must be replaced. However, because the feed port of the adsorption dryer is small, when refilling the adsorbent, the adsorbent may become clogged at the feed port or fall off, making feeding inconvenient.

[0003] The desiccant feeding device for an adsorption dryer provided in the related technology includes a storage tank, a straight pipe, and a connecting flange. The top of the storage tank has an opening, and the bottom of the storage tank is connected to the straight pipe, which is connected to the flange. The flange is fixedly connected to the feeding port of the adsorption tower. The packaging of the adsorbent is opened and then placed into the storage tank. It enters the adsorption tower by gravity through the straight pipe and the flange. However, during the feeding process, the adsorbents rub against each other, causing the adsorbents to clog the storage tank, preventing the adsorbents from entering the adsorption tower.

[0004] Therefore, there is an urgent need for a feeding device for a dryer used in tobacco power plants to solve the above problems. Utility Model Content

[0014] A driving component, connected to the other end of the main body, is configured to drive the main body to rotate on the support assembly, thereby causing the agitator to agitate the adsorbent in the feeding tank.

[0015] As a preferred embodiment, multiple agitators are provided, and the multiple agitators are spaced apart along the extension direction of the main body.

[0016] As a preferred embodiment, the feeding tank includes:

[0029] The beneficial effects of this utility model are:

[0030] This utility model provides a feeding device for a dryer used in a tobacco power plant, used to add adsorbent to the dryer. The feeding device for the dryer includes a feeding barrel, a support assembly, and a stirring assembly. The feeding barrel is detachably fixed to the dryer. A discharge port is provided at the bottom of the feeding barrel, which can communicate with the feed inlet of the dryer. A discharge port is provided at the top of the feeding barrel, through which the adsorbent enters the feeding barrel.

The operator pours the adsorbent into the feeding bucket through the discharge port at the top. The adsorbent falls naturally into the feeding bucket under gravity and moves towards the bottom. The inner spiral structure on the inner wall of the bucket guides the adsorbent to slide down in an orderly manner along the spiral direction, reducing accumulation of adsorbent on the inner wall. Simultaneously, the stirring component rotates around its axis on the support component, stirring and dispersing the adsorbent within the feeding bucket. This ensures that the adsorbent is always in a dynamic environment, allowing it to fall as evenly as possible to the discharge port. The stirring component and the inner spiral structure prevent the adsorbent poured into the feeding bucket from clogging the discharge port, thus increasing the filling speed of the adsorbent in the dryer.

[0043] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] This embodiment provides a feeding device for a tobacco power dryer, used to add adsorbent to the dryer. The feeding device for the tobacco power dryer includes a feeding tank 1, a support assembly 2, and a stirring assembly 3. The feeding tank 1 is detachably fixed to the dryer. The bottom end of the feeding tank 1 has a discharge port 131, which can communicate with the feed inlet of the dryer. The top end of the feeding tank 1 has a discharge port 111, through which the adsorbent enters the feeding tank 1. A portion of the inner wall of the feeding tank 1 is provided with an inner spiral structure 4, which extends axially along the feeding tank 1. The support assembly 2 is fixedly connected to the inner wall of the feeding tank 1, and the stirring assembly 3 is rotatably connected to the support assembly 2. The stirring assembly 3 extends toward the bottom end of the feeding tank 1, and can stir the adsorbent in the feeding tank 1.

[0045] When adding adsorbent to the feed inlet, the feeding tank 1 is fixed to the dryer, ensuring that the discharge port 131 at the bottom of the feeding tank 1 is aligned with the feed inlet of the dryer. The operator pours the adsorbent into the feeding tank 1 through the discharge port 111 at the top. The adsorbent falls naturally into the feeding tank 1 under gravity and moves towards the bottom. At this time, the inner spiral structure 4 on the inner wall of the feeding tank 1 comes into play, guiding the adsorbent to slide down in an orderly manner along the spiral direction, reducing the accumulation of adsorbent on the inner wall of the feeding tank 1. Simultaneously, the stirring component 3 rotates around its axis on the support component 2, stirring and dispersing the adsorbent in the feeding tank 1. This ensures that the adsorbent poured into the feeding tank 1 is always in a dynamic environment, allowing it to fall as evenly as possible to the discharge port 131. Through the stirring component 3 and the inner spiral structure 4, the adsorbent poured into the feeding tank 1 simultaneously is prevented from clogging the discharge port 131, thus improving the filling speed of the adsorbent in the dryer.

[0046] Specifically, in this embodiment, the adsorbent is alumina particles. In other embodiments, the adsorbent is montmorillonite desiccant or silica gel desiccant, etc. No limitations are imposed here.

[0047] Optionally, such as Figure 1 As shown, the stirring assembly 3 includes a main body 31, a stirring element 32, and a driving element 33. The main body 31 is rotatably connected to the support assembly 2. One end of the main body 31 extends toward the bottom of the feeding tank 1. The stirring element 32 is connected to one end of the main body 31 extending toward the bottom of the feeding tank 1. The driving element 33 is connected to the other end of the main body 31. The driving element 33 is configured to drive the main body 31 to rotate on the support assembly 2, so as to drive the stirring element 32 to stir the adsorbent in the feeding tank 1.

[0048] The power of the drive component 33 can be transmitted to the agitator 32 through the main body component 31 to agitate the adsorbent, ensuring that the adsorbent is in a dynamic state in the feeding tank 1. This allows a large amount of adsorbent to fall into the discharge port 131 in batches under the agitation of the agitator 32, preventing the adsorbent from being blocked in the discharge port 131 due to friction. At the same time, if the adsorbent is blocked in the discharge port 131, the rotation of the agitator 32 can disperse the adsorbent at the discharge port 131, thereby reducing the friction between the adsorbents and allowing the adsorbent to fall from the discharge port 131 into the feed port of the dryer.

[0049] Specifically, in this embodiment, the main body 31 is a rotating rod. In other embodiments, the main body 31 is a rotating plate or a rotating frame, etc. No limitations are imposed here.

[0050] Specifically, in this embodiment, the agitator 32 is a blade. In other embodiments, the agitator 32 is a stirring rod, etc. No limitation is made here. More specifically, the agitator 32 is a twisted blade. When the adsorbent falls onto the agitator 32, it is dispersed in different directions, further improving the uniformity of the adsorbent falling into the discharge port 131.

[0051] Specifically, in this embodiment, the driving component 33 is a driving handle. In other embodiments, the driving component 33 is a rotary motor or a rotary cylinder, etc. No limitation is made here.

[0052] Optionally, such as Figure 1 As shown, multiple agitators 32 are provided, and the multiple agitators 32 are spaced apart along the extension direction of the main body 31. By providing multiple spaced agitators 32 along the extension direction of the main body 31, the adsorbent is always in a dynamic state from being poured into the feeding tank 1 to entering the feed inlet of the dryer from the discharge port 131, further preventing the adsorbent from clogging the discharge port 131.

[0053] Specifically, such as Figure 1 As shown, in this embodiment, agitators 32 are connected to opposite sides of the main body 31 in the radial direction. The agitators 32 on both sides of the main body 31 form a symmetrical agitation effect, thereby improving the uniformity of stirring the adsorbent.

[0054] More specifically, such as Figure 1 As shown, in this embodiment, ten agitators 32 are provided, divided into five groups. The five groups of agitators 32 are arranged at intervals along the extending direction of the main body 31, and each group of agitators 32 is welded to opposite sides of the main body 31 along the radial direction of the main body 31. In other embodiments, eight agitators 32 are provided, divided into four groups, or twelve agitators 32 are provided, divided into six groups, etc. No limitation is made here.

[0055] Optionally, such as Figure 1 As shown, the feeding tank 1 includes a tank body 11, a conical tube 12 and a connecting tube 13. The top of the tank body 11 is provided with a discharge port 111. The conical tube 12 is connected to the tank body 11. The conical tip of the conical tube 12 extends in a direction away from the tank body 11. The connecting tube 13 is fixedly connected to the conical tip of the conical tube 12. The connecting tube 13 is provided with a discharge port 131 and is detachably and fixedly connected to the dryer.

[0056] The adsorbent enters from the discharge port 111, passes through the barrel body 11, enters the conical tube 12, and is guided by the tapered shape of the conical tube 12 to smoothly pass through the discharge port 131 of the connecting pipe 13 into the feed port of the dryer. Through the conical tube 12, combined with the gravity of the adsorbent, it is ensured that the adsorbent flows towards the feed port of the dryer without any stagnation. At the same time, the conical tube 12 serves as a transition section connecting the barrel body 11 and the connecting pipe 13. The conical structure guides the inner wall cavity of the feeding barrel 1 from the discharge port 111 to the discharge port 131, thus solving the size matching problem between the barrel body 11 and the connecting pipe 13.

[0057] Specifically, in this embodiment, the material barrel body 11, the tapered tube 12, and the connecting tube 13 are all welded together. In other embodiments, the material barrel body 11, the tapered tube 12, and the connecting tube 13 are all threaded together, etc. No limitations are imposed here.

[0058] Specifically, such as Figure 1 As shown, in this embodiment, the angle α between the sidewall of the tapered tube 12 and the horizontal direction is 60°. In other embodiments, the angle α between the sidewall of the tapered tube 12 and the horizontal direction is 45°, 50°, or 70°, etc. No limitation is imposed here.

[0059] Specifically, such as Figure 1 As shown, in this embodiment, the outer wall of the connecting pipe 13 is threaded, and the connecting pipe 13 is connected to the dryer via the thread. In other embodiments, the connecting pipe 13 is connected to the dryer via a snap-fit ​​structure, etc. No limitations are imposed here.

[0060] Optionally, such as Figure 1 and Figure 2 As shown, the support assembly 2 includes a first support member 21, which is connected to the inner wall of the feeding tank 1. The first support member 21 has a rotation hole 211 through which the agitator 3 passes and is rotatably connected to the first support member 21. The first support member 21 provides support for the rotation of the agitator 3, preventing issues with the reliability and stability of the agitator 3's rotation within the feeding tank 1. Specifically, the first support member 21 provides support for the rotation of the main body 31.

[0061] Further optional, such as Figure 2As shown, the support assembly 2 also includes a second support member 22, which is connected to the inner wall of the feeding barrel 1. The second support member 22 is arranged crosswise with the first support member 21, and the rotating hole 211 is opened at the intersection of the first support member 21 and the second support member 22. The crosswise arrangement of the first support member 21 and the second support member 22 enhances the stability of the support assembly 2, while the location of the rotating hole 211 at the intersection of the two support members ensures the smooth operation of the main body 31. Specifically, in this embodiment, the first support member 21 and the second support member 22 are crosswise, and the center of the rotating hole 211 and the center of the discharge port 131 are on the same axis.

[0062] Specifically, the support assembly 2 also includes a bearing, with the outer ring of the bearing embedded in the rotating hole 211, and the agitator assembly 3 interference-fitted to the inner ring of the bearing. By placing the bearing between the agitator assembly 3 and the rotating hole 211, friction during relative rotation is reduced, further ensuring the rotational flexibility between the agitator assembly 3 and the rotating hole 211. Specifically, the main body 31 is interference-fitted to the inner ring of the bearing.

[0063] Specifically, such as Figure 3 As shown, the inner spiral structure 4 includes multiple arc-shaped protrusions 41 spaced apart along the circumferential direction of the feeding barrel 1. Since the arc-shaped protrusions 41 extend along the axial direction of the feeding barrel 1 and are spaced apart along the circumferential direction of the feeding barrel 1, the spiral structure helps to enhance the stirring effect and promotes the flow of the adsorbent on the inner wall of the feeding barrel 1 or improves the uniformity of mixing.

[0064] Specifically, such as Figure 3 As shown, in this embodiment, the inner spiral structure 4 is disposed on the inner wall surface of the conical tube 12. The guidance of the conical tube 12, combined with the spiral guidance, can further increase the dispersion of the adsorbent on the inner wall surface of the feeding tank 1.

[0065] Specifically, a handle is attached to the outer wall of the feeding hopper 1. The handle facilitates placing the feeding hopper 1 onto the dryer.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
