Description

Technical Field

[0001] This utility model relates to the technical field of tubular chain conveying equipment, specifically a tubular chain conveying device. Background Technology

[0002] A tubular chain conveyor is a continuous conveying device for transporting bulk materials such as powders, small materials, and small lumps. It can transport materials horizontally, inclined, and vertically in combination. Inside a closed pipe, the chain links drive the material to move along the pipe. When conveying horizontally, the material is pushed by the chain links in the direction of movement. When the internal friction between the material layers is greater than the external friction between the material and the pipe wall, the material moves forward with the chain links, forming a stable material flow. When conveying vertically, the material inside the pipe is pushed upward by the chain links. Because the lower feeding prevents the upper material from sliding down, lateral pressure is generated, which increases the internal friction of the material. When the internal friction between the materials is greater than the external friction between the material and the inner wall of the pipe and the weight of the material itself, the material is conveyed upward with the chain links, forming a continuous material flow.

[0003] Traditional tubular chain conveyors, while simple in structure and easy to operate, often have some problems during the conveying process. When conveying materials, the particle size is inconsistent, and they are prone to crossing each other, forming clumps or accumulations, which affects the flowability of the materials, causing local blockages and affecting the conveying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a tubular chain conveying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tubular chain conveyor device, comprising:

[0007] A tubular chain conveyor includes a conveying pipe, the outer wall of which is provided with an inlet and an outlet, and a number of chain pieces are arranged at equal intervals inside the conveying pipe, with a chain fixedly connected between each two adjacent chain pieces;

[0008] A screening mechanism includes a feeding hopper, a dividing hopper on the bottom surface of the feeding hopper, a screen plate between the feeding hopper and the dividing hopper, the screen plate having half large and half small screen holes, the dividing hopper being divided into two areas by a partition, and each area having a discharge port at its bottom, the feeding hopper having a fixed frame fixedly connected to its outer wall, a top plate fixedly connected to the top of the fixed frame, a rotating rod rotatably connected to the bottom surface of the top plate, a servo motor fixedly connected to the top surface of the top plate, the motor shaft of the servo motor passing through the top surface of the top plate and drivingly connected to the top of the rotating rod, a pusher plate fixedly connected to the bottom surface of the rotating rod, a connecting plate sleeved and fixedly connected to the outer wall of the rotating rod, stirring rods rotatably connected to the bottom surfaces of both ends of the connecting plate, and motors fixedly connected to the top surfaces of both ends of the connecting plate, the motor shafts of the two motors passing through the top surface of the connecting plate and drivingly connected to the tops of the two stirring rods respectively.

[0009] Furthermore, an arc-shaped groove is provided at the position where the bottom surface of the feeding bucket and the top surface of the separating bucket are in contact.

[0010] Furthermore, the outer wall of the sieve disc is fixedly connected with a protrusion, which fits into the arc-shaped groove.

[0011] Furthermore, a second fixing ring is fixedly fitted onto the outer wall of the separator, and three supporting legs are fixedly connected at equal angles to the bottom surface of the second fixing ring.

[0012] Furthermore, a fixing ring is fixedly fitted onto the outer wall of the feeding bucket.

[0013] Furthermore, the top surfaces of the first and second fixing rings are perforated with several circular holes at equal angles, and studs are inserted into each of the circular holes, with nuts screwed onto both ends of each stud.

[0014] Furthermore, a discharge mechanism is provided at the bottom of the discharge port. The discharge mechanism includes a discharge box, the top surface of which is connected to the bottom of the discharge port. A second motor is fixedly connected to the side wall of the discharge box, and the motor shaft of the second motor extends through and into the interior of the discharge box to drive and connect a second stirring rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the coordinated arrangement of the feeding bucket, fixed frame, top plate, rotating rod, dividing bucket, discharge port, partition plate and screen plate, and the different apertures on the left and right sides of the screen plate, excessively large materials can be effectively intercepted, ensuring that the materials entering the conveying pipeline are relatively uniform in size. This reduces the cross-linking, clumping or accumulation of materials due to size differences, lowers the risk of blockage, and makes the flow of screened materials in the conveying pipeline smoother. This reduces downtime and maintenance costs caused by blockages, not only improving production efficiency but also extending the service life of the equipment.

[0017] 2. By fixing a first fixing ring to the outer wall of the feeding bucket and a second fixing ring to the outer wall of the separating bucket, and by providing several round holes at equal angles on the surfaces of the first and second fixing rings that mate with the studs, disassembly and replacement are facilitated, simplifying the maintenance process and reducing maintenance costs.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 In this embodiment of the utility model, a tubular chain conveying device includes a tubular chain conveyor 100, which includes a conveying pipe 110. The outer wall of the conveying pipe 110 is provided with an inlet 111 and an outlet 112. A plurality of chain links 113 are evenly spaced inside the conveying pipe 110. A chain 114 is fixedly connected between each pair of adjacent chain links 113. A screening mechanism 200 is provided above the inlet 111. The screening mechanism 200 includes a feeding hopper 210. A dividing hopper 220 is provided on the bottom surface of the feeding hopper 210. A screen plate 230 is provided between the feeding hopper 210 and the dividing hopper 220. The screen holes on the surface of the screen plate 230 are of varying sizes. The interior of the dividing hopper 220 is divided into two areas by a partition 222. Each of the two feeders has a discharge port 221 at its bottom. A fixed frame 211 is fixedly connected to the outer wall of the feeding hopper 210. A top plate 212 is fixedly connected to the top of the fixed frame 211. A rotating rod 213 is rotatably connected to the bottom surface of the top plate 212. A servo motor is fixedly connected to the top surface of the top plate 212. The motor shaft of the servo motor passes through the top surface of the top plate 212 and is connected to the top of the rotating rod 213. A pusher plate 214 is fixedly connected to the bottom surface of the rotating rod 213. A connecting plate 215 is sleeved and fixed to the outer wall of the rotating rod 213. A stirring rod 216 is rotatably connected to the bottom surface of both ends of the connecting plate 215. A motor 217 is fixedly connected to the top surface of both ends of the connecting plate 215. The motor shafts of the two motors 217 pass through the top surface of the connecting plate 215 and are connected to the top of the two stirring rods 216 respectively.

[0028] Specifically, the screen holes on the surface of the screen plate 230 are not the same size on the left and right sides, with the left screen holes being larger than the right screen holes. The bottom surface of the pusher plate 214 is in contact with the surface of the screen plate 230. The screen plate 230 divides the inside of the feeding hopper 210 into two halves. The material is first fed into the side of the feeding hopper 210 where the small screen holes are located, so that the material of similar particle size falls through the small screen holes into the separating hopper 220. The inside of the separating hopper 220 is divided into two halves by the partition plate 222, so that the material with the small diameter falls into the feed inlet 111 through its corresponding discharge port 221, and then into the conveying pipe 110, where it is pushed and conveyed by the chain 113. During the material falling process... Start motor 217. The motor shaft of motor 217 is driven by stirring rod 216. Stirring rod 216 rotates and stirs the accumulated material, accelerating the screening. Material with excessively large particle size is intercepted by screen plate 230. After all the material of suitable particle size in feeding bucket 210 enters conveying pipe 110, servo motor is started to rotate rotating rod 213. The rotating rotating rod 213 drives the pusher plate 214 to rotate, so that the pusher plate 214 pushes the material accumulated in the small aperture area to the large aperture position on the surface of screen plate 230, and the large aperture material is discharged and collected through another discharge port 221 for subsequent conveying.

[0029] like Figure 2 , Figure 5 and Figure 7 As shown, in this embodiment, an arc-shaped groove is provided at the position where the bottom surface of the feeding hopper 210 and the top surface of the separating hopper 220 are in contact, and a protrusion 231 is fixedly connected to the outer wall of the screen plate 230, and the protrusion 231 fits into the arc-shaped groove.

[0030] In this embodiment, when it is necessary to process the larger particle size material that has been intercepted and collected, the protrusion 231 is moved to move along the arc groove, causing the screen plate 230 to rotate. The surface of the screen plate 230 is set to the position of the large aperture, which corresponds to the position of the feed inlet 111. At this time, the larger particle size material is put into the corresponding area in the feeding bucket 210, so that the material passes through the screen plate 230 and enters the conveying pipe 110 through the discharge port 221.

[0031] like Figure 2 , Figure 4 and Figure 7 As shown, in this embodiment, a second fixing ring 223 is fixedly fitted onto the outer wall of the separator 220. Three supporting legs 224 are fixedly connected at equal angles to the bottom surface of the second fixing ring 223. A first fixing ring 218 is fixedly fitted onto the outer wall of the feeding hopper 210. Several circular holes are passed through the top surfaces of the first fixing ring 218 and the second fixing ring 223 at equal angles. A stud 240 is inserted into each of the several circular holes. Nuts 241 are screwed onto both ends of the stud 240.

[0032] In practice, when it is necessary to maintain or replace the screen plate 230, the nut 241 can be unscrewed and the stud 240 can be removed. At this time, the feeding bucket 210 and the dividing bucket 220 can be separated, so that the screen plate 230 embedded between the two can be directly removed, which improves the efficiency of disassembly and installation.

[0033] like Figure 6 As shown, in this embodiment, a discharge mechanism 300 is also provided at the bottom of the discharge port 112. The discharge mechanism 300 includes a discharge box 310. The top surface of the discharge box 310 is connected to the bottom end of the discharge port 112. A second motor 320 is fixedly connected to the side wall of the discharge box 310. The motor shaft of the second motor 320 extends through the discharge box 310 and is connected to a second stirring rod 330.

[0034] In practice, when the material is pushed and conveyed to the discharge port 112 by the chain 113, the material will fall with gravity, start the motor 320, and the motor shaft of the motor 320 is driven by the stirring rod 330, causing the stirring rod 330 to rotate, breaking up the falling material and preventing it from accumulating and sticking together after being conveyed.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
