Abstract

The utility model relates to the field of lime production, in particular to an impurity separation device for lime production. When an existing device is used for separating impurities, quicklime is easily accumulated at one position of a filter screen, so that meshes are blocked by the quicklime, and the separation efficiency is low.

The rotary discharging pipe rotates to drive the sliding pipe to rotate, the sliding pipe rotates to drive the contact frame to slide along the wave-shaped groove, and under the action of the wave-shaped groove, the contact frame drives the sliding pipe to slide on the rotary discharging pipe in a reciprocating mode, so that quicklime containing impurities is more evenly distributed on the filter screen, and lime powder can more smoothly fall off from the filter screen; and the separation efficiency is improved.

Description

Technical Field

[0001] The utility model relates to the field of lime production, in particular to an impurity separation device for lime production. Background Art

[0002] Natural rock is also called quicklime. In actual production, in order to speed up the decomposition, the calcination temperature is often increased by 1 to 10°C. Due to the large size of the limestone raw material or the uneven temperature distribution in the kiln during calcination, the lime often contains under-fired lime and over-fired lime. The two are small particles of calcium carbonate that have not been completely decomposed. They are small in size and numerous in number, and the impurities need to be separated.

[0003] During the separation process of the traditional separation device, quicklime with impurities falls onto the filter through the lower hopper. The quicklime tends to accumulate in one place of the filter, causing the quicklime to block the mesh and resulting in low separation efficiency. Utility Model Content

[0004] In order to overcome the disadvantage that quicklime is easily accumulated in one place of the filter screen, causing the quicklime to block the mesh and resulting in low separation efficiency, the utility model provides an impurity separation device for lime production, which can evenly distribute the quicklime on the filter screen to improve the separation efficiency.

[0005] The technical solution of the utility model is: an impurity separation device for lime production, comprising a separation cylinder, an opening is opened on the side of the separation cylinder, a sealing cover is covered on the opening of the separation cylinder, a top cover is fixedly connected to the top of the separation cylinder, a feed hopper is arranged on the top cover, and a rotating discharge pipe is rotatably connected to the lower part of the feed hopper.

[0006] As a preferred technical solution of the utility model, it also includes a rotating shaft, the rotating shaft is fixedly connected to the rotating discharge pipe, a filter screen is slidably connected to the inside of the separation cylinder, the filter screen is slidably connected to the rotating shaft, six contact shafts are fixedly connected to the bottom surface of the filter screen, and the six contact shafts are evenly spaced.

[0007] As a preferred technical solution of the utility model, it also includes a rotating frame, the lower end of the rotating shaft is fixedly connected to the rotating frame, the rotating frame is located below the filter screen, six protrusions are fixedly connected to the top of the rotating frame, the six protrusions are evenly spaced, the protrusions are in contact with the contact shaft, a motor is provided on the top of the top cover, the output shaft of the motor passes through the top cover, a transmission assembly is connected between the bottom end of the output shaft of the motor and the rotating discharge pipe, and a dust valve is provided at the lower part of the separation cylinder.

[0008] As a preferred technical solution of the utility model, the transmission assembly includes a driving pulley, a passive pulley and a transmission belt, the driving pulley is fixedly connected to the bottom end of the output shaft of the motor, the passive pulley is fixedly connected to the rotating discharge pipe, and a transmission belt is wound between the driving pulley and the passive pulley.

[0009] As a preferred technical solution of the utility model, it also includes a sliding tube, which is slidably connected to the rotating discharge tube, and the sliding tube is communicated with the rotating discharge tube. A contact frame is fixedly connected to the lower part of the sliding tube, and a corrugated groove is opened on the bottom surface of the top cover, and the upper end of the contact frame is located in the corrugated groove.

[0010] Beneficial effects: 1. The rotating frame is driven to rotate by the rotation of the rotating shaft, and the rotation of the rotating frame drives the protrusion to rotate. The rotation of the protrusion pushes the contact shaft upward, and the upward movement of the contact shaft drives the filter to move upward. The protrusion continues to rotate and disengages from the contact shaft. The filter and the contact shaft will fall under the action of gravity, and the quicklime containing impurities on the filter will be shaken. The quicklime powder will fall off the filter, and small particles of calcium carbonate impurities will remain on the filter, making it more convenient to remove the calcium carbonate impurities in the quicklime.

[0011] 2. The sliding tube is driven to rotate by rotating the discharge tube, and the rotation of the sliding tube drives the contact frame to slide along the corrugated groove. Under the action of the corrugated groove, the contact frame drives the sliding tube to slide back and forth on the rotating discharge tube, so that the quicklime containing impurities is more evenly distributed on the filter net, allowing the lime powder to fall from the filter net more smoothly, thereby improving the separation efficiency.

[0024] Initially, the staff pours quicklime containing small particles of calcium carbonate impurities into the feed hopper 21, and then starts the motor 9.

The rotation of the transmission component 10 drives the rotating discharge pipe 3 to rotate clockwise around the rotating shaft 4. During the rotation of the rotating discharge pipe 3, the quicklime containing impurities will be sprinkled on the filter screen 5. The rotation of the rotating discharge pipe 3 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the rotating frame 7 to rotate. The rotation of the rotating frame 7 drives the protrusion 8 to rotate. The rotation of the protrusion 8 pushes the contact shaft 6 upward. The upward movement of the contact shaft 6 drives the filter screen 5 to move upward. , the protrusion 8 continues to rotate and disengages from the contact shaft 6, the filter screen 5 and the contact shaft 6 will fall under the action of gravity, and the quicklime containing impurities on the filter screen 5 will be shaken, and the quicklime powder will be shaken off the filter screen 5, and small particles of calcium carbonate impurities will remain on the filter screen 5, making it more convenient to remove the calcium carbonate impurities in the quicklime.
