Description

Technical Field

[0001] The utility model relates to the technical field of roller kilns, and specifically relates to a roller kiln for calcining talcum powder production. Background Technique

[0002] Calcined talcum powder is a powdery substance sintered from talc ore, which has high thermal stability and wear resistance, and is commonly used in the manufacture of ceramics, coatings, plastics, rubber and other products. When calcining talcum powder, a roller kiln is usually used. A roller kiln is a tunnel kiln with a long and narrow cross-section. Different from a kiln car tunnel kiln, it does not use a kiln car loaded with products to run, but consists of a series of parallel arranged spokes that cross the cross-section of the kiln working channel to form a mixing channel. The products are placed on the mixing channel and are transported into the kiln as the sticks rotate, and the firing process is completed in the kiln, so it is called a roller kiln. Before calcining, the powdery talcum powder needs to be pressed into blocks for easy calcination;

[0003] For example, in the utility model patent with the publication number of CN214892543U, a high-efficiency roller kiln is disclosed. The high-efficiency roller kiln includes a roller kiln, and two first hollow grooves are opened at the lower end of the roller kiln; two second hollow grooves are respectively opened on the upper inner walls of the two first hollow grooves, and baffles are arranged inside the two second hollow grooves; two groups of lifting mechanisms, each group of lifting mechanisms includes a thread groove, a threaded rod, a worm and a worm gear. The thread groove is opened at the upper end of the baffle, and the lifting mechanism can be used to drive the baffle to move up and down, so that when a larger ceramic product passes through the kiln mouth of the roller kiln, the baffle can rise to facilitate the passage of the larger ceramic product, and when a smaller ceramic product passes through the kiln mouth of the roller kiln, the baffle can be lowered through the lifting mechanism;

[0004] However, the pressed block-shaped talcum powder often adheres to dust, and these dusts entering the kiln body will cause pollution, while the existing roller kiln does not have a dust cleaning function and does not meet the existing requirements. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a roller kiln for calcining talcum powder production to solve the problems raised in the above background technique.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A roller kiln for calcining talcum powder production includes a kiln body and a calcining chamber. A cleaning chamber and a dust blowing chamber are arranged on one side of the feeding end of the calcining chamber in the kiln body. Partition plates are arranged between the calcining chamber, the dust blowing chamber and the cleaning chamber, and openings are opened on the partition plates. A lower brush roller and an upper brush roller capable of cleaning the talcum powder blocks are arranged in the cleaning chamber. A plurality of pairs of air blowing cylinders facing the talcum powder blocks are arranged on the upper and lower sides of the talcum powder blocks in the dust blowing chamber, and an air suction cylinder is arranged outside the air blowing cylinder.

[0007] Preferably, an air suction pipe is arranged in the dust blowing cavity, a blowing pipe is arranged in the air suction pipe, the blowing cylinder is connected to the blowing pipe, and the air suction cylinder is connected to the air suction pipe.

[0008] Preferably, one end of the upper brush roller extends to the outside of the kiln body and is fixedly provided with a first gear, one end of the lower brush roller extends to the outside of the kiln body and is fixedly provided with a second gear, and the second gear meshes with the first gear.

[0009] Preferably, a motor is fixedly arranged on the outside of the kiln body, and the other end of the lower brush roller extends to the outside of the kiln body and is connected to the power output end of the motor.

[0010] Preferably, the total air suction volume in the dust blowing cavity is greater than the total air blowing volume.

[0011] The utility model provides a roller hearth kiln for calcining talcum powder production, which has the following beneficial effects: when the talcum powder block moves between the upper brush roller and the lower brush roller, the upper and lower surfaces of the talcum powder block can be cleaned, so as to clean the impurities that are difficult to blow off on the talcum powder block. When the talcum powder block moves to the blowing cylinder, the blowing cylinder can blow off the dust attached to the talcum powder block, and the air suction cylinder outside the blowing cylinder can timely suck out the air with dust, reducing the dust attached to the talcum powder and ensuring the cleanliness inside the kiln body.

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a roller hearth kiln for the production of calcined talc powder, including a kiln body 1 and a calcination chamber 2. A cleaning chamber 3 and a dust blowing chamber 4 are arranged on one side of the feeding end of the calcination chamber 2 inside the kiln body 1. After the talc powder blocks enter the kiln body 1, they pass through the cleaning chamber 3 and the dust blowing chamber 4 in sequence and then enter the calcination chamber 2. Partition plates 5 are provided between the calcination chamber 2, the dust blowing chamber 4, and the cleaning chamber 3. Openings 6 are formed on the partition plates 5 to reduce the air flow between the chambers. A lower brush roller 7 and an upper brush roller 8 capable of cleaning the talc powder blocks are arranged in the cleaning chamber 3. The impurities that are difficult to blow off on the talc powder blocks are cleaned by means of cleaning. A plurality of pairs of air blowing cylinders 9 facing the talc powder blocks are arranged on the upper and lower sides of the talc powder blocks in the dust blowing chamber 4. The dust on the talc powder blocks can be blown off through the air blowing cylinders 9. An air suction cylinder 10 is arranged outside the air blowing cylinder 9, and the gas with dust can be sucked out in time through the air suction cylinder 10.

[0018] As an embodiment of the present utility model, an air suction pipe 12 is arranged in the dust blowing chamber 4. An air blowing pipe 11 is arranged in the air suction pipe 12. The air blowing cylinder 9 is connected to the air blowing pipe 11, and the air suction cylinder 10 is connected to the air suction pipe 12.

[0019] As an embodiment of the present utility model, one end of the upper brush roller 8 extends to the outside of the kiln body 1 and is fixedly provided with a first gear 13. One end of the lower brush roller 7 extends to the outside of the kiln body 1 and is fixedly provided with a second gear 14. The second gear 14 and the first gear 13 are meshed with each other to realize the opposite rotation directions of the upper brush roller 8 and the lower brush roller 7.
