Description
Technical Field
[0001] The utility model relates to the technical field of lime kilns and relates to a dust-free lime kiln feeding device. Background Art
[0002] In the existing lime production process, materials are generally fed into the lime kiln chamber through a belt conveyor and a rotary hopper. However, due to the height difference, dust is generated at the feed port of the rotary hopper, causing serious environmental pollution on site. Therefore, a Chinese patent application with publication number CN216103857U discloses a rotary hopper with dust suppression function, which includes a material bell, a hopper, a cantilever, a motor, a hydraulic cylinder, a lifting frame and a fixed frame. The hydraulic cylinder is installed on the fixed frame through the cantilever, and a lifting frame capable of reciprocating up and down is installed on the piston rod of the hydraulic cylinder. A motor is installed at the bottom of the lifting frame, and the motor is connected to the material bell through a connecting shaft. The hopper is supported on the material bell. The rotary hopper is characterized in that Brackets are provided on the left and right sides of the hopper, and a dust cover is fixedly installed on the bracket corresponding to the position above the feed port of the hopper. A connecting shaft through hole is provided in the middle of the dust cover, and the connecting shaft is inserted into the connecting shaft through hole. A drop-out port is penetrated on the dust cover, and a cylindrical dust cover covering the outside of the hopper is fixedly connected to the bottom surface of the dust cover. Although this patent reduces dust flying out by providing a dust cover, the hopper will rotate and rise and fall during the feeding process. In order to ensure that the rotating hopper can work normally, the dust cover cannot fit tightly with the hopper. This results in some dust flying out from the gap between the dust cover and the hopper during actual use, thereby polluting the on-site environment. Summary of the invention
[0003] The utility model provides a dust-free lime kiln feeding device, which overcomes the shortcomings of the prior art and can effectively solve the problems of large dust and pollution of the working environment during the feeding process of the prior lime kiln feeding device.
[0004] The technical solution of the utility model is realized by the following measures: A dust-free lime kiln feeding device includes a rotary hopper, a belt conveyor, a dust removal pipeline, a dust removal fan and a dust collector. The rotary hopper includes a feed bell, a hopper, a motor, a hydraulic cylinder, a lifting frame and a fixed frame. The hydraulic cylinder is installed on the fixed frame. A lifting frame capable of reciprocating up and down is installed on the piston rod of the hydraulic cylinder. A motor is installed at the bottom of the lifting frame. The motor is connected to the feed bell through a connecting shaft. A hopper is supported on the feed bell. A floor partition is provided above the hopper. A material dropping port is provided on the floor partition corresponding to the position of the hopper. A belt conveyor is provided at the top of the floor partition corresponding to the position of the material dropping port. A connecting shaft through hole is provided on the floor partition. The connecting shaft passes through the connecting shaft through hole. A cylindrical dust-proof cover covering the outside of the hopper is fixedly connected to the bottom surface of the floor partition. The outer side wall of the hopper and the inner side wall of the dust-proof cover are in clearance fit. A dust removal pipeline is fixedly connected to the outer side wall of the dust-proof cover. A dust removal port communicating with the dust removal pipeline is provided through the dust-proof cover inside and outside. The dust removal pipeline is connected to the dust collector through the dust removal fan.
[0005] The following is a further optimization and / or improvement of the above utility model solution:

The other end of the connecting pipe is connected to the dust removal fan. The cross section of the annular pipe is in a "C" shape with the opening facing the dust-proof cover. The upper and lower side walls of the open end of the annular pipe respectively extend upward and downward to form annular connecting edges. The connecting edges and the dust-proof cover are fixedly installed together by bolts. A plurality of dust removal ports are provided at intervals in the circumferential direction on the dust-proof cover corresponding to the position of the annular pipe.
[0007] The above dust-proof cover can be a rubber cover.
[0008] The structure of the utility model is reasonable. By setting a dust-proof cover, a dust removal pipeline, a dust removal fan and a dust collector, during the process of the belt conveyor conveying materials into the hopper, the dust flying out from the feeding port of the hopper is directly sucked into the dust removal pipeline and sent to the dust collector for treatment, thus preventing the dust from flying out from the gap between the dust-proof cover and the hopper and protecting the on-site environment.

DETAILED DESCRIPTION
[0012] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.
[0013] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached manual. Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.
[0014] The present invention is further described below in conjunction with the embodiments and drawings:
[0015] As attached Figure 1-2 As shown, the dust-free lime kiln feeding device includes a rotary hopper 5, a belt conveyor 1, a dust removal pipeline, a dust removal fan 2 and a dust collector 3. The rotary hopper 5 includes a material bell 4, a hopper 5, a motor 6, a hydraulic cylinder 7, a lifting frame 8 and a fixed frame 9. The hydraulic cylinder 7 is installed on the fixed frame 9. The piston rod of the hydraulic cylinder 7 is installed with a lifting frame 8 that can reciprocate up and down. The bottom of the lifting frame 8 is installed with a motor 6, and the motor 6 is connected to the material bell 4 through a connecting shaft. The material bell 4 supports the hopper 5. A floor partition 10 is provided above the hopper 5, corresponding to the position of the hopper 5. A material dropping port is provided on the floor partition 10, and a belt conveyor 1 is provided on the top of the floor partition 10 corresponding to the position of the material dropping port. A connecting shaft through hole is provided on the floor partition 10, and the connecting shaft is passed through the connecting shaft through hole. A cylindrical dust cover 11 covering the outside of the hopper 5 is fixedly connected to the bottom surface of the floor partition 10, and the outer wall of the hopper 5 and the inner wall of the dust cover 11 are gap-matched. A dust removal duct is fixedly connected to the outer wall of the dust cover 11, and a dust removal port 12 connected to the dust removal duct is provided inside and outside the dust cover 11, and the dust removal duct is connected through the dust removal fan 2 and the dust collector 3.
[0016] According to requirements, the dust cover 11 is a rubber cover, the dust collector 3 is a bag filter, the gap between the outer side wall of the hopper 5 and the inner side wall of the dust cover 11 is 0.5 to 1 centimeter. During installation and use, the hopper 5 is installed above the lime kiln. When feeding, the material is added into the hopper 5 through the belt conveyor 1, and the bell 4 is driven to rotate by the motor 6. Since the hopper 5 is supported by the bell 4, the hopper 5 can be driven to rotate when the bell 4 rotates, thereby ensuring that the height of the material surface in the hopper 5 is uniform. After the feeding is completed, the hopper 5 stops rotating, and the hydraulic cylinder 7 drives the lifting frame 8 to descend. Thus, the bell 4 drives the hopper 5 to descend. When the bell 4 drives the hopper 5 to descend to a certain position, at this time, the hopper 5 sits on the top of the lime kiln and does not move, and then the bell 4 continues to descend into the kiln chamber, and the material enters the kiln chamber along the gap between the bell 4 and the hopper 5. After the feeding is completed, the lifting frame 8 rises and resets. In this application, by setting the dust cover 11, the dust removal pipeline, the dust removal fan 2 and the dust collector 3, during the process of the belt conveyor 1 transporting the material into the hopper 5, the dust blown out from the feeding port of the hopper 5 is directly sucked into the dust removal pipeline and sent to the dust collector 3 for treatment, thereby avoiding the dust from blowing out through the gap between the dust cover 11 and the hopper 5 and protecting the on-site environment.
[0017] According to actual needs, the above embodiments can be further optimized or / and improved as follows:
[0018] As shown in the attached Figure 1-2 figure, the dust removal pipeline includes an annular pipe 13 arranged on the outer side wall of the dust cover 11 and a connecting pipe 14 fixedly connected to one end of the annular pipe 13. The other end of the connecting pipe 14 is connected to the dust removal fan 2. The cross-section of the annular pipe 13 is in a "C" shape with the opening facing the dust cover 11. The upper and lower side walls of the open end of the annular pipe 13 extend upward and downward respectively to form an annular connecting edge 15. The connecting edge 15 and the dust cover 11 are fixedly installed together by bolts 16. A plurality of dust removal ports 12 are arranged at intervals along the circumference on the dust cover 11 corresponding to the position of the annular pipe 13. By setting the annular pipe 13 and arranging a plurality of dust removal ports 12 at intervals along the circumference on the dust cover 11 corresponding to the position of the annular pipe 13, the dust suction effect on the dust in the dust cover 11 is ensured, and the annular pipe 13 and the dust cover 11 are fixedly installed together by bolts 16, which is convenient for installation.
[0019] The above technical features constitute the best embodiment of the present utility model, which has strong adaptability and the best implementation effect. Non-essential technical features can be added or subtracted according to actual needs to meet the requirements of different situations.
