Description

Technical Field

[0001] The present disclosure relates to the technical field of battery production and recycling, and in particular to a carbon column unloading mechanism and an activated carbon unloading device. Background Art

[0002] In the process of battery recycling, activated carbon columns are usually used to remove oil from waste battery materials. After the activated carbon in the activated carbon column is saturated with oil, it needs to be replaced in time. The industry usually digs out the activated carbon in the activated carbon column manually. However, with the continuous improvement of battery production capacity, the frequency of replacement of activated carbon in the activated carbon column also increases. This will not only greatly increase the labor intensity of the operators, but also cause carbon powder to fly. Therefore, some manufacturers have carried out further research and development.

[0003] For example, Chinese patent document CN216072192U discloses an activated carbon unloading mechanism including a storage barrel, a conical cover is fixedly connected to the bottom of the storage barrel, a vertical pipe is fixedly connected to the bottom of the conical cover, a discharge pipe is fixedly connected to the bottom of the vertical pipe, a box body is fixedly connected to the right side of the vertical pipe, a second rotating rod is provided in the inner cavity of the box body, a plurality of baffles are fixedly connected to the outer edge of the second rotating rod, a vertical plate is provided on the front side of the box body, and a second bearing is fixedly connected to the vertical plate near the bottom.

[0004] However, the design of the above-mentioned activated carbon unloading mechanism has the following problems:

[0005] Although the above-mentioned activated carbon unloading mechanism can reduce the labor intensity by continuously removing the activated carbon through the rotation of the toggle rod, the activated carbon in the activated carbon column is difficult to be quickly removed due to the combined effect of factors such as the difficulty of the toggle rod to extend in the activated carbon column and the poor fluidity of the activated carbon in the activated carbon column after being saturated with oil. Ultimately, the activated carbon column's material replacement efficiency is still low. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0036] Combine 1 with Figure 2 As shown, a charcoal column unloading mechanism 100 of an embodiment includes a loose material feeding assembly 110 and a spiral unloading paddle 120; the loose material feeding assembly 110 includes a loose material feeding cover 1110, a connecting pipe 1120 and a material extraction conduit 1130 connected in sequence; a bulk material cavity 1116 is provided in the loose material feeding cover 1110, and the bulk material cavity 1116 is connected to the tube cavity of the material extraction conduit 1130 through the tube cavity of the connecting pipe 1120; the spiral unloading paddle 120 is respectively provided in the bulk material cavity 1116, the tube cavity of the connecting pipe 1120 and the material extraction conduit 1130; a plurality of carbon inlets 1115 are provided on the loose material cover 1110, and each carbon inlet 1115 is connected to the bulk material chamber 1116; the spiral material digging paddle 120 is divided into a material shaking section 1210 and a material feeding section 1220 which are connected to each other; the material shaking section 1210 is rotatably arranged in the bulk material chamber 1116, and is respectively arranged opposite to each carbon inlet 1115 to stir and disperse the activated carbon; the material feeding section 1220 is rotatably arranged in the cavity of the extraction conduit 1130 to drive the activated carbon to be transmitted along the extraction conduit 1130.

[0037] It can be understood that by connecting each charcoal inlet 1115 to the bulk material chamber 1116, the activated carbon can enter the bulk material chamber 1116 through the charcoal inlet 1115. Because the shaking section 1210 is rotatably arranged in the bulk material chamber 1116 and is respectively arranged opposite to each charcoal inlet 1115, when the spiral digging paddle 120 rotates, the shaking section 1210 rotates in the bulk material chamber 1116, and the activated carbon is loosened and dispersed due to the shaking action of the shaking section 1210. The loosened activated carbon has enhanced fluidity and can be driven by the spiral digging paddle 120 to enter the lumen of the extraction conduit 1130, and the feeding section 1220 synchronously rotates in the lumen of the extraction conduit 1130, so that the activated carbon can be rapidly transported along the extraction conduit 1130 driven by the feeding section 1220. Compared with the activated carbon unloading mechanism in the prior art, the carbon column discharging mechanism 100 of this embodiment can extend into the interior of the carbon column. At the same time, the shaking of the spiral discharging paddle 120 can effectively improve the fluidity of the activated carbon, thereby enabling the activated carbon to be quickly transported along the extraction conduit 1130, thereby increasing the efficiency of replacing the activated carbon in the carbon column.

[0038] Combination Figure 2 and Figure 3 As shown, in the present embodiment, the loose material cover 1110 is further provided with a charcoal outlet 1117, and both ends of the connecting tube 1120 are respectively provided with an embedded feeding portion 1121 and an embedded discharging portion 1122; the embedded feeding portion 1121 is embedded in the charcoal outlet 1117, and the bulk material cavity 1116 is connected to the tube cavity of the connecting tube 1120 through the embedded feeding portion 1121; the embedded discharging portion 1122 is embedded in the feeding port 1131 of the extraction duct 1130, and the tube cavity of the connecting tube 1120 is connected to the tube cavity of the extraction duct 1130 through the embedded feeding portion 1121. It can be understood that by embedding the embedded feed part 1121 in the charcoal outlet 1117, and by embedding the embedded discharge part 1122 in the feed port 1131 of the extraction duct 1130, it can be connected to the loose material cover 1110 and the extraction duct 1130 respectively through the connecting pipe 1120, and the structure is compact, simple and easy to assemble.

[0039] In one embodiment, a dispersion auxiliary paddle 1230 is further provided in the bulk material chamber 1116; the dispersion auxiliary paddle 1230 extends along the side wall of the shaking material section 1210 and is radially protruding. It can be understood that by providing the dispersion auxiliary paddle 1230 in the bulk material chamber 1116, because the bulk material chamber 1116 is radially protruding from the shaking material section 1210, the radial acting area of ​​the shaking material section 1210 on the activated carbon is increased. When the spiral digging paddle 120 rotates, the dispersion auxiliary paddle 1230 can rotate synchronously with the shaking material section 1210 of the spiral digging paddle 120 to shake and disperse the activated carbon, so that the activated carbon can be dispersed more finely, and finally the fluidity of the activated carbon is further improved.

[0040] Combination Figure 2As shown, in this embodiment, the material shaking section 1210 extends in an axial spiral and forms a plurality of first matching bends 1211; the dispersion auxiliary paddle 1230 extends in an axial spiral and forms a plurality of second matching bends 1231; each first matching bend 1211 is adapted and connected to each second matching bend 1231 one by one. It can be understood that because each first matching bend 1211 is adapted and connected to each second matching bend 1231 one by one, a tight connection structure can be formed between the material shaking section 1210 and the dispersion auxiliary paddle 1230, which is not easy to fall apart during the material shaking process and is more durable.

[0041] Combination Figure 2 As shown, in one embodiment, the material loosening cover 1110 includes a locking ring 1111, a plurality of support guardrails 1112 and a connecting ring 1113; the locking ring 1111, the connecting ring 1113 and the spiral digging paddle 120 are located on the same axis O, the locking ring 1111 is close to and directly opposite to the material shaking section 1210, and the inner ring of the connecting ring 1113 forms a charcoal outlet 1117; a plurality of support guardrails 1112 are arranged around the outer circumference of the material shaking section 1210, the first ends of the support guardrails 1112 converge and are embedded in the locking ring 1111, and the second ends of the support guardrails 1112 are spaced apart on the outer ring wall of the connecting ring 1113, and a charcoal inlet 1115 is formed between two adjacent support guardrails 1112. It can be understood that by making the first ends of the support guardrails 1112 converge and embed in the locking ring 1111, the first ends of the support guardrails 1112 can be tightly gathered and locked together through the locking ring 1111, and by making the second ends of the support guardrails 1112 spaced apart on the outer ring wall of the connecting ring 1113, multiple support guardrails 1112 are arranged around the outer periphery of the shaking material segment 1210, so that the shaking material segment 1210 can be protected by the support guardrails 1112 to prevent the shaking material segment 1210 from directly contacting the activated carbon, thereby effectively preventing the shaking material segment 1210 from being damaged during the process of extending into the carbon column. At the same time, because the carbon inlet 1115 is formed between two adjacent support guardrails 1112, the activated carbon is less likely to flow into the bulk material chamber 1116 through the carbon inlet 1115 at one time and cause blockage under the restriction of the support guardrails 1112.

[0042] Combination Figure 2As shown, specifically, the support guardrail 1112 includes a gathering and embedding portion 111a, an expansion section 111b, a gathering section 111c and a connecting portion 111d which are arranged in sequence; the gathering and embedding portion 111a is embedded in the locking ring 1111, and the expansion section 111b extends obliquely from the gathering and embedding portion 111a to the gathering section 111c; the gathering section 111c is arranged on the side of the shaking material section 1210, and extends and connects to the connecting portion 111d; the connecting portion 111d is fixed on the outer ring wall of the connecting ring 1113. It can be understood that by embedding the gathering embedded part 111a in the locking ring 1111, the gathering embedded part 111a can be firmly fixed and not easy to fall apart, and by making the expansion section 111b extend obliquely from the gathering embedded part 111a to the gathering section 111c, the expansion section 111b can be stretched to the side of the shaking material section 1210, so that the bulk material cavity 1116 has a wider space, and by extending the gathering section 111c to connect to the connecting part 111d, and fixing the connecting part 111d on the outer ring wall of the connecting ring 1113, the gathering section 111c can be better gathered to the connecting part 111d and cover the periphery of the shaking material section 1210, thereby playing a better protective role.

[0043] Combination Figure 3 As shown, in one embodiment, the connecting ring 1113 extends into the bulk material cavity 1116 and is formed with a compression material ring 1114; the compression material ring 1114 surrounds the circumference of the material shaking section 1210; the bulk material cavity 1116 is connected to the lumen of the connecting tube 1120 through the compression material ring 1114. It can be understood that because the compression material ring 1114 surrounds the circumference of the material shaking section 1210, the bulk material cavity 1116 is connected to the lumen of the connecting tube 1120 through the compression material ring 1114, so that the activated carbon dispersed in the bulk material cavity 1116 can enter the extraction conduit 1130 through the compression material ring 1114 under the shaking action of the material shaking section 1210, and the dispersed activated carbon will be compressed and gathered under the action of the compression material ring 1114, and can enter the extraction conduit 1130 more smoothly.

[0044] In one embodiment, the inner ring of the compression feeding ring 1114 is divided into a wide-mouth feeding chamber 111e and a variable-diameter pressing chamber 111f, which are connected along the axis O; the shaking section 1210 is sequentially arranged in the wide-mouth feeding chamber 111e and the variable-diameter pressing chamber 111f; the wide-mouth feeding chamber 111e is connected to the bulk material chamber 1116; the variable-diameter pressing chamber 111f is close to the connecting ring 1113 and is connected to the tube cavity of the connecting tube 1120. It can be understood that because the shaking section 1210 is sequentially arranged in the wide-mouth feeding chamber 111e and the variable-diameter pressing chamber 111f, and the wide-mouth feeding chamber 111e is connected to the bulk material chamber 1116, the scattered activated carbon can enter the compression feeding ring 1114 more and faster through the wide-mouth feeding chamber 111e, further improving the transmission efficiency of the activated carbon unloading device 10 of this embodiment.

[0045] Specifically, the cross section of the variable diameter pressing cavity 111f is gradually reduced from the wide-mouth feeding cavity 111e to the connecting tube 1120. It can be understood that by gradually reducing the cross section of the variable diameter pressing cavity 111f from the wide-mouth feeding cavity 111e to the connecting tube 1120 to form a conical structure, when the scattered activated carbon passes through the variable diameter pressing cavity 111f, it can be compressed and gathered along the cavity wall of the variable diameter pressing cavity 111f, so that the scattered activated carbon flows more closely and is more convenient for the transmission of the spiral digging paddle 120.

[0046] The present disclosure also provides an activated carbon unloading device 10 including a waste storage bin 200, a rotating driver 300 and a carbon column discharging mechanism 100 of any of the above-mentioned embodiments; the carbon column discharging mechanism 100 is arranged on the outside of the waste storage bin 200, and the rotating driver 300 is arranged in the inner cavity of the waste storage bin 200; the discharge port 1132 of the extraction conduit 1130 is connected to the inner cavity of the waste storage bin 200, and is arranged opposite to the rotating driver 300; the end of the feeding section 1220 extends out of the discharge port 1132 of the extraction conduit 1130, and is fixedly connected to the power output end 310 of the rotating driver 300. It can be understood that, because the discharge port 1132 of the extraction conduit 1130 is connected to the inner cavity of the waste storage bin 200, the end of the feed section 1220 is fixedly connected to the power output end 310 of the rotary driver 300, so that the feed section 1220 can be driven to rotate by the rotary driver 300, and the feed section 1220 synchronously drives the dispersion section to rotate, and finally the entire spiral digging paddle 120 rotates in the loose feeding assembly 110. When the loose cover 1110 extends into the carbon column, the spiral digging paddle 120 can automatically disperse and transport the activated carbon, and transfer the dug out activated carbon to the inner cavity of the waste storage bin 200, and facilitate centralized processing, so that the use of the activated carbon unloading device 10 of this embodiment is more intelligent, labor-saving, and practical, and finally the activated carbon in the carbon column can be efficiently replaced. Specifically, the rotary driver 300 can be an electric motor or a hydraulic motor, etc., which is not limited here, and those skilled in the art can also replace it as needed.

[0047] In one embodiment, for better understanding, the activated carbon unloading device 10 of the above embodiment is described as follows:

[0048] When in use, first extend the dispersing section of the loose material hood 1110 and the spiral digging paddle 120 into the carbon column, then start the rotary driver 300, which drives the feeding section 1220 to rotate, and the feeding section 1220 synchronously drives the dispersing section to rotate, and finally the entire spiral digging paddle 120 rotates in the loose material feeding assembly 110, and the activated carbon enters the dispersing chamber from the carbon inlet 1115 of the loose material hood 1110, where it is broken up, and the broken up activated carbon is transported along the extraction conduit 1130 driven by the spiral digging paddle 120, and finally is transported from the discharge port 1132 of the extraction conduit 1130 to the inner cavity of the waste storage bin 200.

[0049] Compared with the prior art, the present invention has at least the following advantages:

[0050] 1) By making each carbon inlet 1115 connected to the bulk material chamber 1116, the activated carbon can enter the bulk material chamber 1116 through the carbon inlet 1115. Because the shaking section 1210 is rotatably arranged in the bulk material chamber 1116 and is respectively arranged opposite to each carbon inlet 1115, when the spiral digging paddle 120 rotates, the shaking section 1210 rotates in the bulk material chamber 1116, and the activated carbon is loosened and dispersed by the shaking action of the shaking section 1210. The loosened activated carbon has enhanced fluidity and can be driven by the spiral digging paddle 120 to enter the lumen of the extraction conduit 1130, and the feeding section 1220 synchronously rotates in the lumen of the extraction conduit 1130, so that the activated carbon can be quickly transported along the extraction conduit 1130 under the drive of the feeding section 1220.

[0051] 2) Compared with the activated carbon unloading mechanism in the prior art, the carbon column discharging mechanism 100 disclosed in the present invention can extend into the interior of the carbon column, and at the same time, the shaking of the spiral discharging paddle 120 can effectively improve the fluidity of the activated carbon, thereby enabling the activated carbon to be quickly transported along the extraction conduit 1130, thereby increasing the efficiency of replacing the activated carbon in the carbon column.

[0052] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
