Description

Technical Field

[0001] The present invention relates to the technical field of gypsum preparation, and in particular to a gypsum preparation production line assembly. Background Art

[0002] Gypsum is widely used in many industries, including building materials and chemicals. For example, in the construction sector, plaster of Paris is a key raw material for the production of lightweight wall materials such as gypsum board and gypsum blocks, as well as building decoration materials. Natural dihydrate gypsum, as raw gypsum, undergoes a series of processing steps, including calcination and drying, before use to convert it into forms such as hemihydrate gypsum. At present, the existing gypsum drying methods have many disadvantages. Traditional gypsum drying often uses a simple drying drum, in which the wet gypsum is transported to the feed hopper by a roller conveyor belt, and then enters the drying drum to be dried in contact with the hot air flow. During this process, the wet gypsum is in a relatively simple contact with the hot air flow in the drying drum, and mainly relies on the temperature difference between the hot air flow and the wet gypsum to evaporate moisture. The heat exchange efficiency is low, resulting in long drying time and high energy consumption. Although there is a scooping plate inside the drying drum, which can scoop up the gypsum and sprinkle it down to promote heat exchange, due to the limitations of the scooping plate structure and layout, the gypsum is unevenly distributed in the drum, and some gypsum is difficult to fully contact with the hot air flow, resulting in poor drying effect and uneven product quality. Existing belt-type gypsum drying equipment typically dries the material by blowing hot air from above or from the side. The contact area and contact time between the hot air and the gypsum material are limited, and a large amount of hot air is discharged before it can fully transfer heat to the material, resulting in low heat exchange efficiency. The time required for wet gypsum to be dried after entering the equipment is long, making it difficult to meet the demand for efficient drying in large-scale production. For example, in some construction gypsum powder production companies, the low drying efficiency has restricted the improvement of overall production capacity. In addition, belt-type gypsum drying equipment is generally set to a longer time to increase the heating time of the material, which places great demands on the site. Summary of the Invention

[0003] The purpose of the present invention is to provide a gypsum preparation production line assembly in order to solve the above problems, as described in detail below.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: The present invention provides a gypsum production line assembly, comprising a box and a rotary kiln device, wherein a multi-layer belt conveyor is horizontally installed in the box, and the conveying directions of two adjacent multi-layer belt conveyors are opposite, and the belt conveyor on the lower layer is used to receive materials from the upper belt conveyor; A drying and blowing assembly is fixedly mounted on the box body, and is used to blow high-temperature airflow to the upper side of all belt conveyors. A high-efficiency drying assembly 1 is fixedly mounted in the box body, and is used to guide the airflow of the drying and blowing assembly so that the airflow covers the upper side of the belt conveyor and stirs the material on the surface of the belt conveyor so that the material can be evenly contacted with the high-temperature airflow. A scattering assembly is fixedly installed between two adjacent belt conveyors to scatter and turn over the materials on the upper belt conveyor so that the parts of the materials that fall to the lower belt conveyor that have not yet been exposed to the high-temperature airflow face upwards; Several high-efficiency drying components 2 connected to the drying and blowing components are fixedly installed in the box body, which are used to stir the materials on the upper side of the belt conveyor and transport the high-temperature airflow into the material; The rotary kiln device is connected to the bottom of the box through a discharge hopper, and is used to receive the materials transported by the belt conveyor at the bottom. The rotary kiln device includes a rotating kiln body, and a vibrating screen assembly is provided in the kiln body. When the kiln body rotates, it cooperates with the vibrating screen assembly to lift and vibrate the materials, thereby further breaking up some agglomerated materials.

[0005] Using the above-mentioned gypsum production line assembly, the gypsum raw materials to be dried are put into the feeding hopper of the box body, and the raw materials will fall onto the belt conveyor on the top layer. As the belt conveyor rotates, the raw materials will fall one by one from the top layer of the belt conveyor to the belt conveyor on the next layer, and finally enter the rotary kiln device through the discharge hopper; By stacking multiple belt conveyors, the length of the device can be effectively shortened, while the time for the material to be dried can be increased. In addition, when the material falls from the upper belt conveyor to the lower belt conveyor, it passes through the dispersing assembly, which can break up the agglomerated material, so that the material can be more dispersed on the lower belt conveyor, thereby improving the drying efficiency. After the material falls to the lower belt conveyor, it can be turned over, so that the material that was not directly exposed to the high-temperature airflow can be directly dried.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 22As shown, the present invention provides a gypsum preparation production line assembly, including a box body 1 and a rotary kiln device 3. A multi-layer belt conveyor 27 is horizontally installed in the box body 1. The conveying directions of two adjacent multi-layer belt conveyors 27 are opposite, and the belt conveyor 27 on the lower layer is used to receive materials from the belt conveyor 27 on the upper layer. The belt conveyor 27 is a prior art. The material of the conveyor belt of the belt conveyor 27 is not limited, as long as it can withstand the temperature in the box body 1. The motor of the belt conveyor 27 is arranged outside the box body 1 to prevent the high temperature in the box body 1 from damaging the motor; A drying and blowing assembly 5 is fixedly mounted on the housing 1 and is used to blow high-temperature air to the upper side of all the belt conveyors 27. A high-efficiency drying assembly 29 is fixedly mounted inside the housing 1 and is used to guide the airflow of the drying and blowing assembly 5 so that the airflow covers the upper side of the belt conveyors 27 and stirs the material on the surface of the belt conveyors 27 so that the material can be evenly contacted with the high-temperature airflow. A breaking assembly 28 is fixedly installed between two adjacent belt conveyors 27 to break up and flip the materials on the upper belt conveyor 27 so that the parts of the materials that fall to the lower belt conveyor 27 and have not yet been exposed to the high-temperature airflow face upwards. By stacking multiple belt conveyors 27, the length of the device can be effectively shortened, while the time for the material to be dried can be increased. In addition, when the material falls from the upper belt conveyor 27 to the lower belt conveyor 27, it passes through the dispersing assembly 28. The dispersing assembly 28 can disperse the agglomerated material, so that the material can be more dispersed on the lower belt conveyor 27, thereby improving the drying efficiency. After the material falls to the lower belt conveyor 27, it can be turned over, so that the material that was not directly exposed to the high-temperature airflow can be directly dried. Several high-efficiency drying components 2 30 connected to the drying and blowing components 5 are fixedly installed in the box 1, which are used to stir the materials on the upper side of the belt conveyor 27 and transport the high-temperature air flow into the material; The material laid on the belt conveyor 27 has a certain thickness. Considering the actual situation, the temperature of the high-temperature airflow is difficult to penetrate into the material, so the flat material is stirred and the high-temperature airflow is output into the material, which can accelerate the drying efficiency of the material; The rotary kiln device 3 is connected to the bottom of the box body 1 through the discharge hopper 4, which is used to receive the materials transported by the lowest belt conveyor 27. The rotary kiln device 3 includes a rotating kiln body 7, and a vibrating screen assembly 15 is provided in the kiln body 7. When the kiln body 7 rotates, it cooperates with the vibrating screen assembly 15 to lift and vibrate the materials, thereby further breaking up some agglomerated materials.

[0021] As an optional embodiment, the rotary kiln device 3 has a base 11, and a kiln tail 9 and a kiln head 10 are fixedly connected on both sides of the base 11. The kiln body 7 is rotatably connected between the kiln tail 9 and the kiln head 10. A rotating component 8 is fixedly connected to the base 11 for rotating the kiln body 7. The smoke exhaust of the kiln tail 9 is connected to a bag dust collector 12. A burner 13 is installed on the kiln head 10, and the burner 13 penetrates the kiln body 7. As a prior art, the rotary kiln device 3 is distinguished from the existing rotary kiln only in the various components in the kiln body 7. The heat source of the rotary kiln device 3 is not limited to the burner 13, and other equivalent methods can also be used instead, such as an electric heating device surrounding the kiln body 7. A waving assembly 36 is fixedly connected to the kiln body 7, which is used to increase the contact time between the unit material and the inner wall of the kiln body 7, and at the same time can pour the material downward from the top of the inner wall of the kiln body 7. A heat dissipation assembly 6 is fixedly installed on the kiln body 7. From the kiln tail 9 to the kiln head 10, the heat dissipation assembly 6, the vibrating screen assembly 15 and the waving assembly 36 are arranged in sequence in the kiln body 7. The heat dissipation assembly 6 can dissipate heat from the material and further stir the material.

[0022] The heat dissipation assembly 6 includes a plurality of heat dissipation pipes 34, which pass through the kiln body 7. Both ends of the heat dissipation pipes 34 are open and sealed with the surface of the kiln body 7. The plurality of heat dissipation pipes 34 are distributed in the kiln body 7 in a spiral shape. Baffles 35 are fixedly connected to both sides of the heat dissipation pipes 34 on the sides corresponding to the rotation direction of the kiln body 7, which are used to gather materials. The length of the baffles 35 is shorter than that of the heat dissipation pipes 34. A blower 33 is fixedly connected to the base 11. The air outlet of the blower 33 is fixedly connected to an air hood 31. The air hood 31 wraps around the kiln body 7 and all the heat dissipation pipes 34. The air hood 31 is connected to the kiln head 10 through the return air pipe 32, so that the gas that absorbs the heat from the heat dissipation pipes 34 enters the kiln body 7. The blower 33 inputs air flow into the heat dissipation pipe 34. The heat dissipation pipe 34 contacts with the material and absorbs the heat of the material, which will be reduced by the blower 33, thereby realizing slow cooling of the material. The slow cooling meets the process requirements of gypsum cooling. The relevant specific content is the existing technology and will not be repeated here. The air flow generated by the blower 33 absorbs heat after passing through the heat dissipation pipe 34 and will enter the kiln body 7 through the air hood 31 and the return air duct 32 to avoid heat waste. In addition, the air hood 31 will not interfere with the rotation of the kiln body 7. The air hood 31 and the surface of the kiln body 7 are clearance-matched or rotationally connected.

[0023] The heat source of the rotary kiln device 3 is located away from the heat pipe 34, so its heat will not directly act on the heat pipe 34. In practice, the heat output of the heat source can be adjusted according to specific circumstances to avoid energy waste caused by excessive drying.

[0024] The vibrating screen assembly 15 includes a baffle 14 and a mounting column 40. The baffle 14 is fixedly connected to the base 11 along the length direction of the kiln body 7. The mounting column 40 is fixedly connected to the kiln body 7 along the axis of the kiln body 7 through two fixing rods 41. The two fixing rods 41 are fixedly connected to the two ends of the mounting column 40 respectively. A plurality of sieve plates 37 are rotatably connected to the surface of the mounting column 40, and the side of the sieve plate 37 away from the mounting column 40 is arc-shaped and contacts the inner wall of the kiln body 7. A plurality of fixing seats 43 corresponding to the plurality of sieve plates 37 are fixedly connected to the inner wall of the kiln body 7. A sliding rod 44 is slidably connected to the fixing seat 43. The curvature of the sliding rod 44 matches the swinging trajectory of the sieve plate 37. A spring 45 is sleeved on the surface of the sliding rod 44. The two ends of the spring 45 are fixedly connected to the sieve plate 37 and the fixing seat 43 respectively. The side of the sieve plate 37 facing away from the sliding rod 44 A guide block 47 is fixedly connected, and a slope is provided on the side of the guide block 47 facing away from the sieve plate 37. A plurality of polygonal rods 48 are radially slidably connected along the mounting column 40 on the kiln body 7. The plurality of polygonal rods 48 correspond to the plurality of guide blocks 47 respectively. Semicircular plates 46 and rollers 49 are fixedly connected at both ends of the polygonal rod 48 respectively. The rollers 49 contact the slope of the guide block 47. A spring 2 50 is sleeved on the surface of the polygonal rod 48. The two ends of the spring 2 50 are fixedly connected to the semicircular plate 46 and the surface of the kiln body 7 respectively. A plurality of baffles 2 42 matching the sieve plate 37 are fixedly connected to the inner wall of the kiln body 7, and the side of the sieve plate 37 facing away from the slide rod 44 contacts the baffle 2 42. When the semicircular plate 46 is blocked when passing through the baffle rod 14, it will drive the polygonal rod 1 48 and the roller 49 to push the guide block 47, so that the sieve plate 37 is away from the baffle 2 42. The sieve plate 37 rotates with the kiln body 7. When the material passes through the sieve plate 37, it can be lifted by the sieve plate 37. At the same time, the sieve plate 37 can vibrate the material. If the material is lumped, it can be shaken away by the sieve plate 37. When the semicircular plate 46 passes through the baffle 14 and is blocked, it will drive the polygonal rod 1 48 and the roller 49 to push the guide block 47, so that the sieve plate 37 is away from the baffle 2 42. After the semicircular plate 46 passes through the baffle 14, it loses its obstruction, and the spring 1 45 pushes the sieve plate 37 to return to its original position, so that the sieve plate 37 hits the baffle 2 42 to generate vibration.

[0025] The swinging assembly 36 includes a plurality of inclined plates 38 equidistantly connected to the inner wall of the kiln body 7 along the length direction of the kiln body 7. A fixed plate 39 is fixedly connected to the side of the inclined plate 38 corresponding to the kiln tail 9. The space formed between the inclined plate 38 and the inner wall of the kiln body 7 is used to accommodate the material. In the prior art, the degree of tumbling of the material in the kiln body 7 is limited. The greater the tumbling degree, the better the drying effect, and vice versa. In the prior art, the reason why the material tumbles less is that the material cannot slide down as the kiln body 7 rotates to a higher height. The inclined plate 38 can rotate the material to the top of the inner wall of the kiln body 7. As the kiln body 7 continues to rotate, the material will slide down to the lowest point in the kiln body 7. In this way, the material can be lifted up in the kiln body 7, so that the material is fully in contact with the heat, thereby improving the drying efficiency.

The nozzle 77 and the paddle 76 rotate with the disc-shaped shell 79 to stir the material. In addition, the material contains a lot of moisture before drying, so the airflow will not blow the material away, causing it to float away from the belt conveyor 27 in the box 1. In addition, even if the material is not dusty, by controlling the wind speed of the drying and blowing assembly 5, the material on the belt conveyor 27 can be prevented from being completely blown away.

In this process, the material will be rearranged, so that after the material falls to the belt conveyor 27 on the lower layer, the undried part faces upward to be directly dried by the airflow.

[0030] A feeding hopper is provided on the top of the box body 1. The side of the box body 1 corresponding to the rotary kiln device 3 is connected to the kiln body 7 of the rotary kiln device 3 through the air guide 16.

[0031] The temperature range in the kiln body 7 is between 150 and 200 degrees, which is in line with the gypsum processing standards. Within this temperature range, the components arranged in the kiln body 7 can be made of conventional metal materials, thereby reducing costs.

In addition, when the material falls from the upper belt conveyor 27 to the lower belt conveyor 27, it passes through the dispersing assembly 28. The dispersing assembly 28 can disperse the agglomerated material, so that the material can be more dispersed on the lower belt conveyor 27, thereby improving the drying efficiency. After the material falls to the lower belt conveyor 27, it can be turned over, so that the material that was not directly exposed to the high-temperature airflow can be directly dried. The drying and blowing assembly 5 is used to blow a high-temperature airflow toward the material on the upper side of the belt conveyor 27. The high-efficiency drying assembly 1 29 can guide the airflow so that the airflow swings back and forth and blows toward the upper side of the belt conveyor 27, so that the high-temperature airflow fully covers the belt conveyor 27.

The high-efficiency drying assembly 1 29 cooperates with the belt conveyor 27 to stir the material laid on the surface of the belt conveyor 27 into a plurality of wavy shapes, so that the material can fully contact the high-temperature airflow. The material can be further stirred by the high-efficiency drying assembly 2 30, and the high-temperature airflow of the drying and blowing assembly 5 is simultaneously introduced into the material. After the preliminary drying treatment, most of the moisture of the material is removed and then enters the rotary kiln device 3 for further drying. When the kiln body 7 rotates, it cooperates with the vibrating screen component 15, the waving component 36 and the heat dissipation component 6 to continuously lift the material, so that the material is fully in contact with the high-temperature air in the kiln body 7 and the material is fully dried. The vibrating screen component 15 can also vibrate the material to further vibrate the larger particles to disperse them. Depending on the type of material, the heat dissipation component 6 can be used to reduce the temperature of the material to be discharged.
