Description

Technical Field

[0001] The invention belongs to the technical field of ceramsite production, and particularly relates to a granulator and process for ceramsite production. Background Art

[0002] Ceramic aggregate is a lightweight aggregate, usually made from fired clay, and is widely used in construction, gardening, civil engineering and other fields. In the production process of ceramsite, it does need to go through processes such as ball milling and granulation. After the raw materials are crushed into smaller particles, the fine powdered raw materials are converted into granular materials, which are convenient for subsequent sintering and use.

[0003] After the granulator squeezes the raw material into small pieces, the granular material is generally squeezed out by a telescopic cylinder and a top block. Since the raw material powder may have a strong adhesion with the inner wall of the molding groove after extrusion, long-term repeated use may cause wear of the internal components of the cylinder and leakage of the seal, increasing the equipment cost. The conventional mechanical extrusion method is difficult to generate a large impact force in the narrow molding groove, and the material may be stuck. The practicality is poor. This phenomenon has become a problem that needs to be solved urgently by people in this field. Summary of the invention

[0004] The purpose of the present invention is to provide a granulator and process for producing ceramsite in accordance with the existing material collection device, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a granulator for ceramsite production, comprising a machine base, a motor is installed on one side of the machine base, the output end of the motor is connected to a rotating shaft through a coupling, the rotating shaft and the machine base are rotatably connected through a bearing, one end of the rotating shaft is connected to a granulating roller, a fixing rod is fixedly installed on the other side of the machine base, one end of the fixing rod extends into the inner wall of the granulating roller, the fixing rod and the inner wall of the granulating roller are movably connected through a bearing, the outer wall of the granulating roller is evenly provided with forming grooves, a feed trough is installed on the top of the machine base, and a discharge trough is installed on the bottom of the machine base. When in use, the motor is started to drive the granulating roller to rotate slowly for granulation, the raw materials are put into the feed trough, and the granular materials are squeezed into the discharge trough after granulation to complete the collection of the finished products.

[0006] The present invention further states that a push block is slidably mounted on the inner wall of the discharge trough, a sliding rod is fixedly mounted on one side of the push block, a connecting rod is slidably sleeved on the outer wall of the sliding rod, the granulation roller is a hollow structure, and guide holes are evenly opened on the inner wall of the granulation roller, and the connecting rod is in sliding contact with the inner wall of the guide hole. The guide hole is used to guide the movement of the connecting rod, and at the same time connects the molding trough with the inner wall of the granulation roller to facilitate the discharge of waste gas and water. The sliding rod is also used to guide the push block.

[0007] The present invention further states that a cam is fixed to the outer wall of the fixing rod by welding, an expansion opening is provided at one end of the guide hole extending outward, an expansion block is connected to one end of the connecting rod, the expansion block and the cam are a matching structure, the expansion block fits with the expansion opening, a spring is sleeved on the outside of the connecting rod, and the two ends of the spring are in contact with the expansion block and the inner wall of the granulating roller respectively. When the expansion block fits with the cam, the connecting rod cannot move, the spring stores energy when compressed, and when the expansion block and the cam are separated from each other, the spring returns to its original state and pops the expansion block upward.

[0008] The present invention further states that a limit block is installed on the inner wall of the molding groove, an electronic igniter is installed on the inner wall of one side of the molding groove, and the electronic igniter is embedded in the interior of the granulating roller. When the hydrogen and oxygen in the molding groove are mixed, the electronic igniter ignites to cause the hydrogen and oxygen to explode in the molding groove, and the thrust generated by the combustion causes the push block to move outward until the limit block and the push block are engaged with each other for limiting.

[0009] The present invention further illustrates that the inner wall of the granulating roller is evenly provided with an air inlet, one end of the air inlet is connected with the forming groove, and the other end of the air inlet is connected with the inner wall of the granulating roller, and the inner wall of the granulating roller is evenly provided with a wall-attached tube, and an electronic valve is connected between the wall-attached tube and the air inlet. When the electronic valve is opened, gas can be introduced, and when the electronic valve is closed, gas leakage can be prevented, and the mixed gas is introduced into the air inlet through the wall-attached tube and then into the forming groove.

[0010] The present invention further illustrates that an annular tube is installed at one end of the granulation roller, one end of the wall-attached tube passes through the outer wall of the granulation roller, and one end of the wall-attached tube is connected to the annular tube, and a hydrogen tank and an oxygen tank are arranged at one end of the granulation roller, and both the hydrogen tank and the oxygen tank are connected to the annular tube. The hydrogen tank and the oxygen tank are used to supply gas to the inside thereof, and the gas will enter the annular tube and then enter the inside of the wall-attached tube to realize the circulation of gas. In this way, gas can be supplied while rotating; one end of the hydrogen tank and the oxygen tank is connected to an air pump to provide power for the supply of gas.

[0011] The present invention further states that the granulating roller is placed at an inclined angle, and a drain pipe is installed at the lower end of the granulating roller, and one end of the drain pipe is connected to the inner wall of the granulating roller. The drain pipe is used to drain excess water when it rotates to the bottom of the granulating roller; the combustion products generated in the forming groove will flow out to the inner wall of the granulating roller along the guide hole.

[0012] The present invention further describes a processing technology of a granulator for producing ceramsite, comprising:

[0013] S1. Start the motor to make the two granulating rollers rotate towards each other, add raw material powder into the feeding trough, close the granulating rollers and squeeze the raw material powder into the forming trough to form granular materials;

[0014] S2, passing the hydrogen and oxygen mixed gas in the hydrogen tank and the oxygen tank into the air inlet duct, and squeezing them into the forming tank;

[0015] S3, when the forming groove rotates to align with the cam, the cam squeezes the expansion block inward, causing the connecting rod to move into the forming groove;

[0016] S4, start the electronic valve to make the mixture of hydrogen and oxygen explode, and the released energy pushes the push block outward to complete the extrusion of the granular material;

[0017] S5. When the forming groove rotates to other positions, the spring returns to its original state and makes the forming groove interpenetrate with the inner wall of the granulating roller. When it rotates to the top, the water produced by the combustion flows out from the guide hole.

[0018] S6. When the forming trough rotates to the horizontal direction, the raw material powder enters the forming trough and causes the push block to slide inward, completing a working cycle.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention uses the instantaneous impact force generated by the explosion of hydrogen and oxygen in the molding groove to push the push block outward to complete the extrusion of the granular material. Compared with the pushing of the traditional telescopic cylinder, it will not cause wear of the internal components of the cylinder and leakage of the seals, and the large impact force can avoid the problem of material jamming. The water generated by the combustion of hydrogen and oxygen can also conveniently moisten and clean the inner wall of the molding groove to avoid the powdered raw material from sticking to the inner wall.
