Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon production equipment, and in particular to a crushing and conveying device for activated carbon production. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials (such as fruit shells, coal, and wood) are heated in the absence of air to reduce non-carbon components (a process called carbonization). They then react with gases, causing surface erosion and creating a highly porous structure (a process called activation). Because activation is a microscopic process, involving numerous point-like erosions of molecular carbides, activated carbon has countless tiny pores on its surface.

[0003] When producing activated carbon, we need to first crush the raw materials for making activated carbon, and then transport these crushed raw materials to the activated carbon activation equipment for further production. However, the current crushing equipment directly uses grinding devices to crush activated carbon, which has low working efficiency and poor grinding uniformity. At the same time, most of the existing crushing equipment has only one discharge pipe, which cannot realize multi-station conveying of activated carbon, reducing the practicality of the equipment. Utility Model Content

[0004] The purpose of this application is to provide a crushing and conveying device for activated carbon production, in order to solve the problems of current crushing equipment directly using grinding devices to crush activated carbon, resulting in low working efficiency and poor grinding uniformity during the grinding process. At the same time, most existing crushing equipment has only one discharge pipe, which cannot realize multi-station conveying of activated carbon, thus reducing the practicality of the device.

[0005] To address the aforementioned technical problems, this application provides a crushing and conveying device for activated carbon production, comprising a crushing cylinder, a crushing motor fixedly installed at the top of the crushing cylinder, a rotating shaft connected to the output shaft of the crushing motor, a pre-crushing assembly inside the crushing cylinder, a guide hopper fixedly connected to the side wall of the crushing cylinder below the pre-crushing assembly, a crushing box connected to the bottom of the guide hopper via a discharge tank, a discharge screw fixedly connected to the bottom of the rotating shaft and located inside the discharge tank, a crushing roller inside the crushing box, a feeding pipe fixedly connected to the bottom of the crushing cylinder, an upper connecting plate welded to the bottom of the feeding pipe, a lower connecting plate at the bottom of the upper connecting plate, a conveying shell connected to the bottom of the lower connecting plate via a feed pipe, and multiple discharge pipes fixedly connected to the bottom of the conveying shell, each of the multiple discharge pipes being equipped with a control valve.

[0006] Preferably, the pre-crushing component includes a filter basket fixedly disposed on the inner wall of the crushing cylinder, the filter basket having a plurality of evenly distributed filter holes, and a crushing blade fixedly disposed on the rotating shaft, the crushing blade being located above the filter basket.

[0007] Preferably, a conveying motor is fixedly installed on one side of the conveying shell, the output shaft of the conveying motor is connected to a rotating rod, and a spiral blade is fixedly installed on the surface of the rotating rod.

[0008] Preferably, the bottom of the conveying shell is connected to three discharge pipes.

[0009] Preferably, a feed hopper is connected to the top of the crushing cylinder.

[0010] Preferably, the lower surface of the upper connecting plate is provided with a fixing groove, and the upper surface of the lower connecting plate is fixed with a fixing plate, wherein the fixing groove and the fixing plate are fitted together.

[0011] Preferably, threaded holes are provided inside the fixing plate and the upper connecting plate, and fixing bolts are threaded into the threaded holes.

[0012] Compared with the prior art, the crushing and conveying device for activated carbon production provided by this utility model has at least the following beneficial effects:

[0013] 1. A pre-crushing component is installed inside the crushing cylinder to pre-crush the activated carbon. The pre-crushed activated carbon falls into the feed hopper, and then the crushing motor drives the discharge screw to rotate, conveying the pre-crushed activated carbon to the grinding box for grinding. This allows qualified materials to pass through the grinding roller quickly, avoiding the accumulation of a large amount of material at the grinding roller and improving the grinding efficiency. At the same time, the cooperation between the pre-crushing component and the grinding roller can improve the grinding effect of activated carbon.

[0014] 2. After being crushed, the activated carbon enters the discharge shell and is then discharged through multiple discharge pipes at the bottom of the shell, achieving multi-station conveying of activated carbon. At the same time, the conveying motor drives the rotating rod and spiral blades to rotate, which can accelerate the discharge speed of activated carbon and further improve the conveying efficiency.

[0024] Example 1

[0025] A crushing and conveying device for activated carbon production includes a crushing cylinder 2. A crushing motor 8 is fixedly installed on the top of the crushing cylinder 2. The output shaft of the crushing motor 8 is connected to a rotating shaft 9, which extends into the interior of the crushing cylinder 2. A pre-crushing assembly is installed inside the crushing cylinder 2. Below the pre-crushing assembly, a guide hopper 5 is fixedly connected to the side wall of the crushing cylinder 2. Activated carbon processed by the pre-crushing assembly falls onto the guide hopper 5. The bottom of the guide hopper 5 is connected to a crushing box 7 via a discharge tank 6. The guide hopper 5, discharge tank 6, and crushing box 7 are interconnected. The activated carbon falling onto the guide hopper 5 falls into the discharge tank 6 and then into the crushing box 7. Inside the crushing box 7, a discharge screw 11 is fixedly connected to the bottom end of the rotating shaft 9. The discharge screw 11 is located inside the discharge tank 6. In actual use, the crushing motor 8 drives the rotating shaft 9 and the discharge screw 11 to rotate, thereby driving the activated carbon downward to be conveyed into the crushing box 7. A crushing roller 12 is installed inside the crushing box 7. A drive shaft is connected to the middle of the crushing roller 12. One end of the drive shaft is fixedly connected to an external motor (the external motor is not shown in the figure). The external motor drives the drive shaft to rotate, thereby causing the crushing roller 12 to rotate. The activated carbon is finely crushed by the crushing roller 12, which improves the crushing efficiency of the activated carbon.

[0026] A feed pipe 13 is fixedly connected to the bottom of the crushing cylinder 2. An upper connecting plate 14 is welded to the bottom of the feed pipe 13. A lower connecting plate 15 is provided at the bottom of the upper connecting plate 14. A discharge hole is opened between the upper connecting plate 14 and the lower connecting plate 15. The bottom of the lower connecting plate 15 is connected to a conveying shell 21 through a feed pipe 16. The activated carbon in the crushing cylinder 2 enters the conveying shell 21 at the bottom through the feed pipe 13 and the feed pipe 16. Multiple discharge pipes 25 are fixedly connected to the bottom of the conveying shell 21. Each of the multiple discharge pipes 25 is equipped with a control valve 26. When conveying activated carbon, the material is quickly conveyed to multiple workstations for processing through the multiple discharge pipes 25 at the bottom of the conveying shell 21, which improves the conveying efficiency.

[0027] In this embodiment, preferably, the pre-crushing component includes a filter basket 3 fixedly installed on the inner wall of the crushing cylinder 2. The activated carbon added to the crushing cylinder 2 first falls onto the filter basket 3. The filter basket 3 is provided with several evenly distributed filter holes 4. The activated carbon particles are filtered through the filter holes 4. Small particles smaller than the filter holes 4 fall into the feed hopper 5, eliminating the need for repeated crushing and improving crushing efficiency. A crushing blade 10 is fixedly installed on the rotating shaft 9. The crushing blade 10 is located above the filter basket 3. The crushing motor 8 drives the rotating shaft 9 and the crushing blade 10 to rotate. The rotating crushing blade 10 performs preliminary crushing of large activated carbon particles until the activated carbon particles can pass through the filter basket 3, and then pass through the crushing roller 12 for further crushing and grinding.

[0028] To further improve the conveying efficiency of activated carbon, preferably, a conveying motor 22 is fixedly installed on one side of the conveying shell 21. The output shaft of the conveying motor 22 is connected to a rotating rod 23. A spiral blade 24 is fixedly installed on the surface of the rotating rod 23. When the crushed activated carbon enters the conveying shell 21, the conveying motor 22 is started. The conveying motor 22 drives the rotating rod 23 to rotate, which in turn causes the spiral blade 24 to rotate, thereby accelerating the discharge speed of the activated carbon.

[0029] In this embodiment, preferably, the bottom of the conveying shell 21 is connected to three discharge pipes 25, which are used to transport activated carbon to three workstations for further processing, thereby improving the conveying efficiency.

[0030] In this embodiment, preferably, a feed hopper 1 is connected to the top of the crushing cylinder 2, and the material to be crushed is quickly added into the crushing cylinder 2 by using the feed hopper 1 at the top of the crushing cylinder 2.

[0032] Based on the above embodiment 1, a crushing and conveying device for activated carbon production has a fixing groove 17 on the lower surface of the upper connecting plate 14 and a fixing plate 18 fixed on the upper surface of the lower connecting plate 15. The fixing groove 17 and the fixing plate 18 fit together, and the fixing plate 18 is snapped into the fixing groove 17, so that the upper connecting plate 14 and the lower connecting plate 15 can be connected together. Preferably, threaded holes 19 are provided inside the fixing plate 18 and the upper connecting plate 14. Fixing bolts 20 are threaded into the threaded holes 19, and the fixing bolts 20 are fixed in the threaded holes 19, which can fix the fixing plate 18 in the upper connecting plate 14, thereby fixing the upper connecting plate 14 and the lower connecting plate 15. In actual use, when it is necessary to disassemble the conveying shell 21, the fixing bolts 20 in the threaded holes 19 are removed, and the conveying shell 21 is pulled down, so that the fixing plate 18 is disengaged from the fixing groove 17, the upper connecting plate 14 and the lower connecting plate 15 are separated, and the lower conveying shell 21 can be disassembled for maintenance.

[0033] The activated carbon production crushing and conveying device provided in this application operates as follows: Large-particle activated carbon is fed into the crushing cylinder 2 through the feed hopper 1. The activated carbon first falls onto the filter basket 3. The crushing motor 8 is started, driving the rotating shaft 9 and the crushing blades 10 to rotate. The rotating crushing blades 10 perform preliminary crushing of the large-particle activated carbon until the activated carbon particles can pass through the filter basket 3. The activated carbon, after being processed by the pre-crushing component, falls onto the guide hopper 5. The crushing motor 8 drives the rotating shaft 9 and the discharge screw 11 to rotate, thereby conveying the activated carbon downwards into the crushing box 7. The motor installed on the outside of the crushing cylinder 2 operates, driving the rotating drive shaft to rotate, thereby causing the crushing roller 12 to rotate, and the activated carbon is finely crushed by the crushing roller 12. The activated carbon in the crushing cylinder 2 enters the conveying shell 21 at the bottom through the discharge pipe 13 and the feed pipe 16. The conveying motor 22 is started, driving the rotating rod 23 to rotate, thereby causing the spiral blades 24 to rotate, thus accelerating the discharge speed of the activated carbon.
