Description

Technical Field

[0001] This utility model belongs to the technical field of dust collection devices, and in particular relates to a dust collection system for loading crushed electrolyte materials. Background Technology

[0002] Dust collection systems are equipment systems used to capture, filter, and remove dust or particulate matter generated during industrial production processes. They are widely used in industries such as metallurgy, building materials, chemicals, power, and machinery processing to ensure a clean production environment, meet environmental protection requirements, and protect worker health.

[0003] In the aluminum electrolysis industry, for example, in the anode assembly workshop, dust collection pipes are used for the dust collection system of crushed material loading and unloading. During the material loading process, the rotating feed tank of the tanker generates a swirling airflow, causing a large amount of dust to overflow and fly, resulting in a significant dust problem. At the same time, the dust collection pipe has a negative pressure suction inside, and there are no obstruction measures to prevent the suction of lumpy and large particles. As a result, some material is drawn away by the dust collection system when the material is unloaded, leading to material waste and a significant increase in the load on the dust collection system. Utility Model Content

[0004] In view of the technical problems existing in the background art, this utility model provides an electrolyte crushed material loading and dust collection system.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] An electrolyte crushing material loading and dust collection system includes a dust collection pipe and a feeding pipe assembly. The feeding pipe assembly includes a first feeding pipe and a second feeding pipe. The first feeding pipe is inclined and inserted into the interior of the dust collection pipe. The second feeding pipe is coaxially arranged with the dust collection pipe and is disposed inside the dust collection pipe. The upper end of the second feeding pipe is connected to the lower end of the first feeding pipe.

[0007] Optionally, a dust collection hood is detachably connected to the bottom end of the dust collection pipe, and a filter disc is provided on the inner wall of the dust collection hood, with the second discharge pipe passing through the inside of the filter disc.

[0008] Optionally, the filter disc has an internal mounting groove, and the outer wall of the second feed pipe has a first flange, which is located in the mounting groove. The first flange and the filter disc are connected by bolts.

[0009] Optionally, the upper end of the second feeding pipe is provided with a conical feeding hopper, and the bottom side of the first feeding pipe is provided with a conical feeding port, which is located in the feeding hopper.

[0010] Optionally, a semi-circular baffle block is provided on the upper side of the hopper, and a conical flow channel and a circular channel are provided on the inner wall of the baffle block from bottom to top. The upper side of the discharge port is located near the flow channel and the circular channel, and the lower side of the discharge port is located near the hopper.

[0011] Optionally, a connecting pipe is inclinedly arranged on the outer side of the dust collection pipe, the first discharge pipe is arranged close to the inner wall of the connecting pipe, a second flange is arranged at the upper end of the first discharge pipe, a third flange is arranged at the upper end of the connecting pipe, and the second flange and the third flange are mated and connected by bolts.

[0012] Optionally, a fourth flange is provided on the bottom side of the dust collection pipe, and a fifth flange is provided on the upper side of the dust collection hood. The fourth flange and the fifth flange are mated and connected by bolts.

[0013] Optionally, the upper inner wall of the dust collection hood is provided with a limiting groove, the filter disc is disposed in the limiting groove, and the bottom side of the dust collection pipe is pressed against the filter disc.

[0014] This utility model has the following advantages and beneficial effects:

[0015] In this invention, the feeding pipe assembly includes a first feeding pipe and a second feeding pipe. The first feeding pipe is inclined and inserted into the interior of the dust collection pipe, while the second feeding pipe is disposed inside the dust collection pipe, with its upper end connected to the lower end of the first feeding pipe. By introducing the feeding pipe into the dust collection pipe for feeding, dust generated during feeding can be accurately collected by the dust collection pipe directly above, reducing the possibility of large amounts of dust overflowing and flying due to the swirling air generated by the rotating feeding of the tanker truck.

[0016] Secondly, by utilizing a filter disc, lumpy and large particles can be blocked from being sucked into the dust collection pipe when dust is collected by the dust collection hood. Furthermore, the second discharge pipe features an optimized upper structure. A hopper is installed on the upper side of the second discharge pipe, corresponding to the discharge port on the bottom side of the first discharge pipe. A semi-circular baffle is placed on one side of the hopper. When material is discharged from the first discharge pipe, lumpy and large particles are blocked, preventing them from being sucked upwards into the dust collection pipe. Simultaneously, the discharge hopper is cone-shaped, extending towards the inner wall of the dust collection pipe. With the first discharge pipe and the baffle above, small particles of powder and dust are effectively blocked on the circumferential surface, reducing the amount of pulverized material drawn into the dust collection pipe, minimizing material waste, and reducing the load on the dust collection system.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Example

[0030] like Figures 1-9As shown, an electrolyte crushed material loading and dust collection system includes a dust collection pipe 1 and a feeding pipe assembly. The feeding pipe assembly includes a first feeding pipe 4 and a second feeding pipe 3. The first feeding pipe 4 is inclined and inserted into the interior of the dust collection pipe 1. The second feeding pipe 3 is coaxially arranged with the dust collection pipe 1 and is located inside the dust collection pipe 1. The upper end of the second feeding pipe 3 is connected to the bottom end of the first feeding pipe 4.

[0031] In this invention, the material is fed into the dust collection pipe 1 through a feeding pipe. The material is fed in at an angle from the first feeding pipe 4 and then vertically discharged into the second feeding pipe 3. When dust is generated during feeding, it can be accurately collected by the dust collection pipe 1 directly above, reducing the possibility of a large amount of dust overflowing and flying due to the swirling wind generated by the rotating feeding of the tanker.

[0032] In this invention, a dust collection hood 5 is detachably connected to the bottom end of the dust collection pipe 1. A filter disc 6 is installed on the inner wall of the dust collection hood 5, with a central hole 61 inside the filter disc 6. A second feeding pipe 3 passes through the central hole 61 of the filter disc 6. The bottom end of the second feeding pipe 3 extends from the bottom side of the dust collection hood 5. During feeding, the dust collection hood 5 covers the feeding position, achieving dust suction during feeding. In this invention, the filter disc 6, when the dust collection hood 5 collects dust, can block lumpy and large particulate materials, preventing them from being sucked into the dust collection pipe 1.

[0033] Furthermore, the filter disc 6 has an internal mounting groove 63, and the outer wall of the second feed pipe 3 has a first flange 31. The first flange 31 is located in the mounting groove 63, and the first flange 31 and the filter disc 6 are connected by bolts. This structure enables the second feed pipe 3 and the filter disc 6 to be detachably connected.

[0034] Furthermore, a vertical section 32 is provided at the upper end of the second discharge pipe 3, and a conical discharge hopper 33 is provided on the vertical section 32. The discharge hopper 33 gradually increases in size upwards, and there is a certain gap between the outer wall of the discharge port 41 and the inner wall of the dust collection pipe 1, allowing dust to be drawn upwards. A conical discharge port 41 is provided on the bottom side of the first discharge pipe 4, and the discharge port 41 gradually decreases in size downwards. The discharge port 41 is located in the discharge hopper 33. Through the cooperation of the discharge port 41 and the discharge hopper 33, the flow direction of the material is changed. After being inclined from the first discharge pipe 4 into the second discharge pipe 3, the material is discharged vertically downwards. Moreover, the discharge hopper 33 is located above the filter plate 6. The conical discharge hopper 33 can block dust and powder, further restrict the flow of powder, prevent fine powder from being drawn away, and reduce resource waste.

[0035] In this invention, a semi-circular baffle block 34 is provided on the upper side of the hopper 33, forming a notch 35 between the baffle block 34 and the hopper 33, and a discharge port 41 is disposed in the notch 35. The inner wall of the baffle block 34 is provided with a conical guide groove 36 and a circular groove 37 from bottom to top. The upper side of the discharge port 41 is located near the guide groove 36 and the circular groove 37, and the lower side of the discharge port 41 is located near the hopper 33. This design allows the baffle block 34 to block the discharge from the second discharge pipe 3, preventing large particles from being sucked upwards during discharge.

[0036] In this invention, by optimizing the structure of the second feeding pipe 3, a feeding hopper 33 is provided on the upper side of the second feeding pipe 3, corresponding to the feeding port 41 on the bottom side of the first feeding pipe 4. A semi-circular baffle block 34 is provided on one side of the feeding hopper 33. When the first feeding pipe 4 discharges material, it blocks blocky and large-particle materials, preventing them from being sucked upward into the dust collection pipe 1. At the same time, the feeding hopper 33 is designed in a conical shape, extending towards the inner wall of the dust collection pipe 1. With the first feeding pipe 4 and the baffle block 34 blocking it on the upper side, it can fully block small-particle powder dust on the circumferential surface, reducing the amount of crushed material sucked into the dust collection pipe, reducing material waste, and reducing the load on the dust removal system.

[0037] Furthermore, a connecting pipe 2 is inclinedly arranged on the outer side of the dust collection pipe 1, and a first feeding pipe 4 is arranged close to the inner wall of the connecting pipe 2. A second flange 42 is provided at the upper end of the first feeding pipe 4, and a third flange 21 is provided at the upper end of the connecting pipe 2. The second flange 42 and the third flange 21 are connected by bolts. This structure facilitates the disassembly and assembly of the first feeding pipe 4.

[0038] Furthermore, a fourth flange 11 is provided on the bottom side of the dust collection pipe 1, and a fifth flange 51 is provided on the upper side of the dust collection hood 5. The fourth flange 11 and the fifth flange 51 are connected by bolts to achieve a detachable connection between the dust collection pipe 1 and the dust collection hood 5.

[0039] Furthermore, a limiting groove 52 is provided on the upper inner wall of the dust collection hood 5, and the filter disc 6 is placed in the limiting groove 52. The filter disc 6 has several filter holes 62 around its circumference, and the bottom side of the dust collection pipe 1 is pressed against the filter disc 6 to fix the filter disc 6.

[0040] This invention not only achieves efficient dust removal during material feeding but also reduces the amount of material being drawn away by the dust collection system, thereby reducing the load on the dust collection system while avoiding resource waste. Furthermore, the first feeding pipe 4, the second feeding pipe 3, and the dust collection pipe 1 all employ a detachable connection structure, making the overall structure easy to disassemble and replace, facilitating replacement when the feeding pipes wear out.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
