Description

Technical Field

[0001] The utility model relates to the technical field of cement production, and more specifically to a clinker dust collecting device used for energy-saving cement production. Background Art

[0002] In the process of cement production, a large amount of dust will be generated when the clinker is shipped out of the warehouse. In order to prevent the dust from floating into the air and affecting the workshop environment, if the dust is not handled in time, it will not only pollute the natural environment but also cause harm to the human body. Therefore, a dust collection device is needed to collect the dust generated when the material is transported out of the warehouse to prevent the dust from spreading.

[0003] Most of the existing clinker dust collection devices use negative pressure fans to extract dust and discharge the extracted dust through dust collection pipes. However, during the dust emission process, as the dust falls from the dust collection pipe, some dust will spread outside the dust collection device, causing secondary pollution to the workshop environment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a clinker dust collecting device for cement energy-saving production, so as to avoid dust flying when the dust collecting pipe drops materials, and improve the dust collecting efficiency.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present utility model are as follows.

[0006] A clinker dust collecting device for energy-saving cement production comprises a dust collecting pipe arranged on a negative pressure fan, a feed pipe for conveying collected dust is arranged at the bottom of the dust collecting pipe, and a dust collecting box for collecting dust conveyed by the feed pipe is arranged at the end of the feed pipe; a conveyor belt for conveying dust is arranged inside the feed pipe, the bottom end of the dust collecting pipe extends into the feed pipe and is located above the conveyor belt, and baffles for preventing dust from flying out are arranged between the bottom end of the dust collecting pipe and the conveyor belt except on one side of the running direction of the conveyor belt; a plurality of buffer plates for buffering falling dust are arranged obliquely and cross-wise on the inner wall of the dust collecting pipe.

[0007] To further optimize the technical solution, baffles for protecting the conveyed dust are provided on both sides of the conveyor belt in the conveying pipe.

[0008] To further optimize the technical solution, a through groove is opened on a side wall of the feed pipe below the conveyor belt, a push plate is provided at the bottom of the feed pipe for pushing the dust at the bottom of the feed pipe into the dust collecting box, and a handle connected to the push plate is provided in the through groove.

[0009] To further optimize the technical solution, accordion-type rubber pads are provided between the two sides of the handle and the two ends of the through groove to prevent dust from flying out of the conveying pipe.

[0010] To further optimize the technical solution, the buffer plate is an elastic steel plate.

[0011] Due to the adoption of the above technical scheme, the technical progress achieved by the present invention is as follows.

[0012] The utility model provides a clinker dust collecting device for energy-saving cement production, which can buffer the dust falling from the dust collecting pipe, reduce the falling speed of the dust, reduce the flying of dust, and make the dust fall directly onto the conveyor belt through the baffle, so as to prevent the dust from flying out of the conveyor pipe, thereby preventing the dust from flying out and polluting the workshop environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model.

[0014] Among them: 1. Dust collecting pipe, 2. Buffer plate, 3. Feeding pipe, 4. Conveyor belt, 5. Baffle, 6. Dust collecting box, 7. Through slot, 8. Accordion rubber pad, 9. Push plate, 10. Handle. DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] A clinker dust collecting device for cement energy-saving production, combined with Figure 1 As shown, it includes a dust collecting pipe 1 arranged on a negative pressure fan, a conveying pipe 3 is arranged at the bottom of the dust collecting pipe 1 for conveying the collected dust, and an ash collecting box 6 is arranged at the end of the conveying pipe 3 for collecting the dust conveyed by the conveying pipe.

[0017] A plurality of buffer plates 2 are arranged crosswise and obliquely downward on the inner wall of the dust collecting pipe 1. The buffer plates are elastic steel plates that can produce elastic deformation when subjected to dust pressure to buffer the dust falling in the dust collecting pipe, so that the dust slowly falls into the conveying pipe and reduces dust flying.

[0018] A conveyor belt 4 is provided inside the feed pipe 3 for conveying dust. The bottom end of the dust collecting pipe 1 extends into the feed pipe 3 and is located above the conveyor belt 4. A baffle 5 is provided between the bottom end of the dust collecting pipe 1 and the conveyor belt 4. The baffle 5 is provided on three sides except one side in the running direction of the conveyor belt to prevent dust from flying out during the falling process and make the falling dust fall on the conveyor belt.

[0019] Baffles 5 are provided on both sides of the conveyor belt 4 in the conveying pipe 3 to protect the dust transported on the conveyor belt and prevent the dust from flying out of the conveyor belt during the dust transportation process. The top end of the baffle 5 is set on the conveying pipe 3, and the bottom end of the baffle 5 does not contact the conveyor belt and will not affect the operation of the conveyor belt.

[0020] A through groove 7 is provided on a side wall of the feed pipe 3 below the conveyor belt 4, and a push plate 9 is provided at the bottom of the feed pipe 3 for pushing the dust at the bottom of the feed pipe into the dust collecting box 6. A handle 10 is provided in the through groove 7, and the inner side of the handle 10 is connected to the push plate 9, and the outer side of the handle 10 extends out of the through groove, so that the staff can hold the handle and push the push plate forward to push the dust at the bottom of the feed pipe into the dust collecting box to avoid dust accumulation at the bottom of the feed pipe.

[0021] In order to prevent dust from flying out of the through slot and polluting the workshop environment when the push plate pushes the dust, accordion-type rubber pads 8 are arranged between the two sides of the handle and the two ends of the through slot. The accordion-type rubber pads can move left and right with the handle to prevent dust from flying out of the conveying pipe when the push plate pushes the dust.

[0022] When the utility model is working, the negative pressure fan absorbs the dust generated when the clinker is discharged from the warehouse, and the dust enters the dust collecting pipe. When the dust is discharged in the dust collecting pipe, the buffer plate is used for buffering, so as to reduce the speed of the dust falling, so that the dust slowly falls on the conveyor belt below. When the dust falls and is transported, the baffle plates on both sides and the rear of the conveyor belt are used for protection, so that the dust is transferred to the dust collecting box through the conveyor belt, and the dust is prevented from flying to the outside of the conveying pipe. In the process of conveying, the handle can be pushed forward to drive the push plate at the bottom of the conveying pipe to push the dust falling on the bottom of the conveying pipe forward, and the dust is pushed into the dust collecting box, so as to avoid the accumulation of dust at the bottom of the conveying pipe.
