Description

Technical Field

[0001] The present invention relates to the technical field of refractory material processing, in particular to a drying system and process for refractory material processing. Background Art

[0002] Refractory materials are used in various fields of the national economy, such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, and military industry. Most of the refractory materials commonly seen in daily life are refractory bricks, and the raw materials of refractory bricks are various refractory particles. The existing process is to process the raw materials prepared on the batching line through a mixer, conveyor, and dryer in sequence. The use of multiple devices not only occupies a large area, but also takes a long time to change molds and clean the equipment, and has high labor costs. After the refractory powder is dried and mixed, there will be powder that is not completely dried in the powder, and these powders will clump together, affecting subsequent processing. Patent documents are now available to improve this.

[0003] For example, Chinese patent CN217698959U discloses a refractory material powder processing device that integrates drying and mixing, comprising a processing box, a mixing device fixedly installed through the lower right end of the processing box, a drying device fixedly installed through the upper end of the processing box, support legs fixedly connected to the four corners of the lower end of the processing box, a filter assembly movably connected through the four support legs, a feed pipe fixedly connected through the middle of the lower end of the processing box, a box door provided at the left front end of the processing box, a safety sensor fixedly installed through the right front end of the processing box, a feed pipe fixedly connected through the middle of the upper end of the processing box, and a feed hopper fixedly connected to the upper end of the feed pipe. The refractory material powder processing device that integrates drying and mixing described in the utility model improves the drying effect while achieving uniform powder mixing by using a drying device and a stirring device, thereby achieving uniform drying and improving processing efficiency.

[0004] Although the above documents improve the drying effect, they still have obvious defects in actual use, such as:

[0005] 1. This equipment dries the material evenly by stirring it, but it also shows that a large amount of material needs to be put into the equipment at one time, otherwise the stirring function will be extremely ineffective. However, a large amount of material input also prolongs the stirring and drying time, reduces efficiency, and cannot form continuous production.

[0006] 2. After the equipment completes drying, the material is discharged through the discharge pipe. However, the discharge pipe is fixed, and a large amount of material will accumulate in the middle to form a slope, which is easy to cause blockage and cannot be effectively screened. Manual spreading of the material is required, with a high failure rate and cumbersome use.

[0007] Therefore, a drying system for refractory material processing with high-efficiency drying and screening functions is now designed to solve such defects. Summary of the Invention

[0013] Preferably, a feeding hopper is fixedly connected to the left side of the top of the drying box through an opening, and a discharge frame is fixedly connected to the right side of the bottom of the drying box through an opening.

[0014] Preferably, the screening and dust removal mechanism includes a screening box, and the screening box is installed at the lower part of the drying mechanism through a bracket.

A spray plate is fixedly connected between the two connecting pipes and located on the inner side of the dust box.

[0017] The present invention also discloses a drying process for refractory material processing, which specifically comprises the following steps:

[0018] S1. Before use, connect the water inlet pipe of the water pump to the water source, then start the motor, and transport the refractory particles through the feeding device and feed them into the drying box through the feeding hopper, and then go to step S2 for the drying process;

[0019] S2, after the motor is started, it drives the second reciprocating screw to rotate. Under the limit of the two second slide plates, the material pump drives the two groups of retraction frames on both sides to move back and forth through the connecting frame. When the retraction frame moves back and forth, the two arc-shaped tooth plates in the same group will mesh with the second gear column and the first gear column in turn during the reciprocating process. Since the upper and lower arc-shaped tooth plates are set in opposite directions, when the retraction frame moves to the left, it is only driven by the lower arc-shaped tooth plate to rotate, and the upper arc-shaped tooth plate retracts to the inside of the retraction frame without driving it to rotate. When moving to the right, the lower arc-shaped tooth plate retracts to the inside of the retraction frame and is only driven to rotate by the upper arc-shaped tooth plate. The upper and lower arc-shaped tooth plates respectively drive the second gear column and the first gear column to rotate The motor will only rotate in one direction, and the three conveyor belts inside the drying box are driven by the cooperation of the pulley and the belt. The refractory particles move when they fall on the top of the conveyor belt. At the same time, the threaded cylinder is driven by the pulley to make the two first reciprocating screws drive the two scrapers to reciprocate and extend under the limit of the slide to flatten the refractory particles. The heating plate increases the temperature to dry them. The refractory particles will first contact the vibration plate when they are handed over at the top of the three conveyor belts. When the vibration plate is contacted, it is vibrated by the first spring so that it has completed the reverse side when it falls on the top of the next conveyor belt, thereby achieving a uniform drying effect. After drying is completed, it drops to the inside of the blanking frame at the bottom, and then goes to step S3 for dust reduction and screening process;

[0020] S3. When the refractory particles fall on the inner side of the discharge frame, the extraction pump extracts the refractory particles through the telescopic material pipe and sprays the dried refractory particles evenly on the top of the screening plate through the reciprocating movement of the extraction pump. During the reciprocating movement, the extraction pump also drives the circular seat to squeeze several round-headed rods. Through the continuous squeezing of several round-headed rods, the screening plate can vibrate back and forth with the third spring under the limit of the sliding seat to screen the refractory particles. When the particles fall under the screening plate, the vacuum pump starts to absorb the dust generated by the screening and spray it on the inside of the dust box. The spray plate sprays water to reduce the dust, and the remaining particles flow out from the bottom of the screening box to complete the drying.

[0021] Preferably, in step S2, the upper and lower arc-shaped tooth plates are arranged oppositely.

[0022] The present invention provides a drying system and process for refractory material processing. Compared with existing technologies, it has the following advantages:

[0023] (1) The drying system for refractory material processing is equipped with a retracting frame and an arc-shaped tooth plate at the front and rear of the drying box, and is connected to the extraction pump through a connecting frame. The extraction pump, driven by the motor, links the screening and dust removal mechanism with the drying mechanism. The arrangement of these structures can quickly dry the refractory material in small amounts and evenly at a time, while forming continuous production to improve efficiency. The subsequent equipment can evenly spray the particles on the top of the screening plate and screen them through linkage, and can also remove dust at the same time, so that the function of the equipment is extended and the amount of dust is reduced, which is satisfactory for current use.

[0024] (2) The drying system for refractory material processing uses only a motor to drive the second reciprocating screw to rotate, and is equipped with two sets of oppositely arranged arc-shaped tooth plates and round-head rods. It can simultaneously complete the movement, screening and spreading of particles during drying, reducing the installation of drive equipment, avoiding excessive damage to energy, and saving production costs.

[0025] (3) The drying system for refractory material processing is provided with a plurality of equidistant round-headed rods on one side of the screening plate and extending to the rear of the screening box through the telescopic opening, and is used in conjunction with a circular seat. The coordinated use of these two structures can make the circular seat hit the round-headed rods while the material pump moves back and forth, thereby achieving a continuous and rapid vibration effect.

[0026] (4) The drying system for processing refractory materials is provided with a vibration plate installed on both sides of the inner cavity of the drying box, and a first spring is installed between one side of the vibration plate and the inner wall of the drying box, and is used in conjunction with a first slider. The arrangement of these structures can vibrate and turn over the refractory particles when they are converted, so that they can be dried evenly and the drying quality is improved.

A spray plate (219) is fixedly connected between the two connecting pipes (218) and located on the inner side of the dust box (215).

6. A drying process for refractory material processing, characterized in that: The drying system for refractory material processing according to claim 1 is used, and the drying process includes the following steps: S1, connect the water inlet pipe of the water pump (217) to the water source, then start the motor (203), and transport the refractory particles through the feeding device and feed them into the drying box (101) through the feeding hopper (126), and then go to step S2 to perform the drying process; S2, after the motor (203) is started, it drives the second reciprocating screw (204) to rotate. Under the limit of the two second slide plates (123), the material pump (206) drives the two groups of retraction frames (118) on both sides to reciprocate through the connecting frame (125). When the retraction frame (118) reciprocates, the two arc-shaped tooth plates (121) of the same group will engage and rotate with the second gear column (127) and the first gear column (112) in the reciprocating process. The arc-shaped toothed plate (121) is arranged opposite to the lower arc-shaped toothed plate (121), so that when the retraction frame (118) moves to the left, it is only driven to rotate by the lower arc-shaped toothed plate (121), and the upper arc-shaped toothed plate (121) retracts into the inner side of the retraction frame (118) without driving rotation. When the retraction frame (118) moves to the right, the lower arc-shaped toothed plate (121) retracts into the inner side of the retraction frame (118) and is only driven to rotate by the upper arc-shaped toothed plate (121). The upper and lower arc-shaped toothed plates (121) respectively drive the second gear column (127) and the first gear column (127). When a gear column (112) rotates, it will only rotate in one direction. Through the cooperation of the pulley (110) and the belt (111), the three conveyor belts (103) inside the drying box (101) are driven. When the refractory particles fall on the top of the conveyor belt (103), they move. At the same time, the threaded cylinder (105) is driven by the pulley (110) to drive the two first reciprocating screw rods (106) to drive the two scrapers (109) to reciprocate and extend under the limit of the slide (108) to move the refractory particles. The refractory particles are flattened, and the heating plate (104) increases the temperature to dry them. When the refractory particles are connected at the top of the three conveyor belts (103), they first contact the vibration plate (115). When the vibration plate (115) is contacted, it is vibrated by the first spring (116), so that when it falls on the top of the next conveyor belt (103), it has completed the reverse side, thereby achieving a uniform drying effect. After the drying is completed, it descends to the inside of the blanking frame (117) at the bottom, and then goes to step S3 for dust reduction and screening process; S3, when the refractory particles fall on the inner side of the discharge frame (117), the extraction pump (206) extracts the refractory particles through the telescopic material pipe (207). The dried refractory particles are evenly sprayed on the top of the screening plate (210) by the reciprocating movement of the extraction pump (206). In the process of reciprocating movement, the extraction pump (206) also drives the circular seat (220) to squeeze the multiple round rods (213). 3) continuous extrusion can make the screening plate (210) vibrate back and forth in combination with the third spring (211) under the limit of the sliding seat (209), so as to screen the refractory particles. When the particles fall under the screening plate (210), the vacuum pump (214) starts to absorb the dust generated by the screening and sprays it on the inside of the dust box (215). The spray plate (219) sprays water to reduce the dust, and the remaining particles flow out from the bottom of the screening box (201) to complete the drying.

7. The drying process for refractory material processing according to claim 6, characterized in that: In the step S2, the upper and lower arc-shaped tooth plates (121) are arranged oppositely.
