Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a magnesium ore feeding device. Background Technology

[0002] Magnesium ore is mainly used in metallurgy, building materials, chemical industry, light industry, agriculture and animal husbandry. In the current technology, magnesium ore needs to go through a gas vertical kiln and a mud-stone separator before it can be used. The cleaned magnesium ore needs to be transported to the next work station, which increases the fatigue of workers and labor costs, and affects subsequent processing and use.

[0003] A search revealed that existing technology CN222086609U describes a magnesium ore feeding device, comprising a gas vertical kiln, a mud-stone separator, and a conveying assembly. The conveying assembly includes two guide rails, a plate chain conveyor belt, two rolling rollers, a rotating shaft, driven teeth, a driving teeth, a drive motor, and a support plate. The other end of the rotating shaft is fixedly connected to the driven teeth, and the driving teeth mesh with each other. When the gas vertical kiln is opened and magnesium ore is added, it falls onto the plate chain conveyor belt after being screened by the mud-stone separator. The drive motor above the support plate is started, causing the driving teeth to rotate, which in turn causes the rotating shaft to rotate the rolling rollers. Since the rolling rollers and the plate chain conveyor belt are in a meshing state, the screened magnesium ore is moved in this way. By conveying the screened magnesium ore in this manner, the fatigue intensity of the workers is reduced, and the labor costs are also reduced, which facilitates subsequent processing.

[0004] However, the above equipment has the following problems when used: when magnesium ore is fed into the gas vertical kiln, the falling ore cannot be buffered and slowed down, which will cause great impact on the gas vertical kiln and seriously reduce the service life of the gas vertical kiln. Utility Model Content

[0005] The purpose of this utility model is to provide a magnesium ore feeding device, which aims to solve the problem that when magnesium ore is fed into a gas vertical kiln, the falling ore cannot be buffered and slowed down, which will cause great impact on the gas vertical kiln and seriously reduce the service life of the gas vertical kiln.

[0006] To achieve the above objectives, this utility model provides a magnesium ore feeding device, including a chain conveyor and a buffer assembly;

[0007] The buffer assembly includes a hopper, a first rotating plate, a second rotating plate, a rotating seat, a positioning block, a first support, a second support, a buffer spring, a guiding component, a dust removal component, and a reinforcing component. The hopper is located below the discharge side of the chain conveyor and is fixed above the receiving hopper of the gas vertical kiln by the support. The first rotating plate is rotatably mounted inside the hopper via the rotating seat, and the second rotating plate is rotatably mounted inside the hopper via the rotating seat. The second rotating plate is connected to the first rotating plate via the positioning block to form an integral rotating plate structure. The first support is detachably installed at the bottom of the first rotating plate and the second rotating plate, respectively. The second support is symmetrically installed on the inner side wall of the hopper. The buffer spring is welded between the first support and the second support. The guiding component is located on the hopper and cooperates with the dust removal component. The reinforcing component is located on the side of the second rotating plate near the first rotating plate.

[0008] The conveyor chain of the chain conveyor is provided with side plates on both sides.

[0009] The guiding component includes a guiding tube and a blocking component. The guiding tube is detachably connected to the hopper, with one end extending into the hopper. The blocking component is disposed on the stepped end of the guiding tube located inside the hopper.

[0010] The blocking component includes a blocking cover and a retaining spring. The blocking cover is detachably connected to the guide tube and is limited by the retaining spring.

[0011] The dust removal component includes a vacuum cleaner and a connecting pipe. The vacuum cleaner is installed on the ground on one side of the gas vertical kiln. The connecting pipe is connected to the inlet of the vacuum cleaner and the outlet of the guide pipe.

[0012] The reinforcing member includes a first reinforcing column and a second reinforcing column. The first reinforcing column and the second reinforcing column are arranged in a line on the second rotating plate and are slidably connected to the first rotating plate. They are also integrally formed with the second rotating plate.

[0013] The buffer assembly further includes a threaded cover, which is threadedly connected to the rotating seat and located outside the rotating seat.

[0014] The magnesium ore feeding device further includes an auxiliary dust removal component, which includes a fixing plate and a cooperating component. The fixing plate is detachably connected to the hopper and is located on the top side of the hopper. The auxiliary dust removal component is disposed on one side of the fixing plate and can cooperate with the vacuum cleaner.

[0015] The mating components include an installation tube and a suction tube. The installation tube is detachably connected to the fixing plate and is located at the top of the hopper. A plurality of suction tubes are threadedly connected to the installation tube and are located at the bottom of the installation tube.

[0016] When the mounting tube is installed, the symmetrical rectangular protrusion on the front side of the limiting plate passes through the mating rectangular cavity on the fixing plate, and a shaft retaining spring is set on the side away from the limiting plate for installation limiting.

[0017] This utility model discloses a magnesium ore feeding device. The hopper can be installed above the receiving hopper of a gas vertical kiln via a bracket. Furthermore, after installation, the first and second rotating plates are symmetrically arranged with the center line of the hopper as the center of symmetry, achieving a buffering effect while sealing the hopper to prevent some dust from floating to the outside. During feeding, the ore is transported by a chain conveyor and falls onto the two symmetrical integral rotating plate structures formed by the assembly of the first and second rotating plates. At this time, buffer springs can buffer the impact. Then, the first and second rotating plates are impacted, opening the feed port, and the buffered and decelerated ore falls into the receiving hopper. This solves the problem in existing feeding devices where the falling ore cannot be buffered and decelerated when magnesium ore is fed into the gas vertical kiln, causing great impact to the gas vertical kiln and seriously reducing its service life.

Furthermore, after installation, the first rotating plate 103 and the second rotating plate 104 are symmetrically arranged with the center line of the hopper 102 as the center of symmetry, achieving a buffering effect while simultaneously sealing the hopper 102 to prevent some dust from floating to the outside. During feeding, the ore is transported via the chain conveyor 101, and the ore falls onto the... On the two symmetrical integral rotating plate structures formed by assembling the first rotating plate 103 and the second rotating plate 104, the buffer spring 109 can provide buffering. Then, the first rotating plate 103 and the second rotating plate 104 are impacted, opening the feed port. The ore, after being buffered and slowed down, falls into the receiving hopper. The dust collector 114 is turned on, and the internal dust can be extracted through the guide pipe 111 and the connecting pipe 115. This solves the problem that when magnesium ore is fed into the gas vertical kiln, the falling ore cannot be buffered and slowed down, which will cause great impact to the gas vertical kiln and seriously reduce the service life of the gas vertical kiln.
