Description

Technical Field

[0001] The present invention relates to the technical field of gypsum preparation, and particularly relates to a static belt drying device for gypsum. Background Art

[0002] In many industries such as building materials and chemical industry, gypsum is widely used. For example, in the construction field, calcined gypsum is a key raw material for producing lightweight wall materials such as gypsum boards and gypsum blocks, as well as building decoration materials. And natural dihydrate gypsum, as raw gypsum, needs to undergo a series of processing treatments such as calcination and drying before use, and is transformed into forms such as hemihydrate gypsum. Existing belt drying devices for gypsum usually dry by blowing hot air from above or the side of the material. The heat source distribution is not uniform enough, resulting in some areas of the gypsum being overheated during the drying process, showing phenomena such as cracking and yellowing, while some areas are insufficiently dried. 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 without fully transferring the heat to the material, resulting in low heat exchange efficiency. The time required for wet gypsum to complete drying from entering the device is relatively long, and it is difficult to meet the demand for efficient drying in large-scale production. For example, in some building gypsum powder production enterprises, due to the low drying efficiency, the overall production capacity is restricted, and the belt drying device for gypsum generally has a relatively long setting for the material heating time, so the requirement for the site is very large. Summary of the Invention

[0019] To make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present invention.

[0020] See Figures 1 - 15 As shown, the present invention provides a gypsum static belt drying device, which includes a box body 1. Inside the box body 1, multiple belt conveyors 14 are horizontally installed. The conveying directions of two adjacent belt conveyors 14 are opposite, and the belt conveyor 14 located at the lower layer is used to receive the materials from the upper belt conveyor 14. The belt conveyor 14 is a prior art, and the material of the conveyor belt of the belt conveyor 14 is not limited as long as it can withstand the temperature inside the box body 1. The motor of the belt conveyor 14 is arranged outside the box body 1 to avoid damage to the motor caused by the high temperature inside the box body 1. A drying air-blowing assembly 3 is fixedly installed on the box body 1, which is used to blow high-temperature air flow to the upper side of all the belt conveyors 14. An efficient drying assembly I 11 is fixedly installed inside the box body 1, which is used to guide the air flow of the drying air-blowing assembly 3 so that the air flow covers the upper side of the belt conveyor 14, and at the same time stir the materials on the surface of the belt conveyor 14 to enable the materials to be in uniform contact with the high-temperature air flow. A dispersing assembly 12 is fixedly installed between two adjacent belt conveyors 14, which is used to disperse and turn over the materials on the upper belt conveyor 14 so that the part of the materials that has not corresponded to the high-temperature air flow and falls onto the lower belt conveyor 14 faces upward. By stacking multiple belt conveyors 14, the length of the device can be effectively reduced, and at the same time, the time for the materials to receive drying treatment can be increased. And when the materials fall from the upper belt conveyor 14 to the lower belt conveyor 14, they pass through the dispersing assembly 12. The dispersing assembly 12 can disperse the agglomerated materials so that the materials can be more dispersed on the lower belt conveyor 14, improving the drying efficiency. And after the materials fall onto the lower belt conveyor 14, they can be turned over so that the materials that were not directly corresponding to the high-temperature air flow can be directly dried. A number of efficient drying assemblies II 15 communicated with the drying air-blowing assembly 3 are fixedly installed inside the box body 1, which are used to stir the materials on the upper side of the belt conveyor 14 and transport the high-temperature air flow into the materials. The materials laid on the belt conveyor 14 have a certain thickness. Considering the actual situation, it is difficult for the temperature of the high-temperature air flow to penetrate into the interior of the materials. Therefore, stirring the laid materials and outputting the high-temperature air flow into the materials can accelerate the drying efficiency of the materials.

[0021] As an alternative embodiment, a feeding hopper 6 and a discharging hopper 4 are fixedly connected and communicated with the top and bottom of the box body 1 respectively. The feeding hopper 6 and the discharging hopper 4 correspond to the belt conveyors 14 on the top layer and the bottom layer respectively. A base 7 is fixedly connected to the bottom of the box body 1, and an air guiding hopper 5 is fixedly communicated with the side surface of the box body 1. The drying air flow in the box body 1 passes through the air guiding hopper 5.

[0022] The high-efficiency drying component II 15 includes a track 46, which is fixedly connected inside the box body 1 and horizontally arranged above the belt conveyor 14. A movable plate 47 is slidably connected in the track 46. A fixed pipe 48 is vertically rotatably connected to the movable plate 47. The lower end of the fixed pipe 48 is fixedly communicated with a disc-shaped shell 49. The lower end of the disc-shaped shell 49 is fixedly communicated with a plurality of jet nozzles 51, and the lower end of the jet nozzle 51 is arc-shaped. An opening is formed in the side wall of the jet nozzle 51, and a dust-proof net 52 is fixedly connected in the opening. A plurality of blades 50 are fixedly connected to the disc-shaped shell 49. The blades 50 and the jet nozzles 51 are both in contact with the upper side of the belt conveyor 14. A gear II 45 is fixedly connected to the surface of the fixed pipe 48. A rack II 44 is horizontally fixedly connected above the track 46. The gear II 45 meshes with the rack II 44. The reciprocating movement mechanism 2 drives the movable plate 47 to reciprocate. The fixed pipe 48 can be rotated through the cooperation of the rack II 44 and the gear II 45. The fixed pipe 48 conveys the high-temperature gas of the drying air blowing component 3 to the disc-shaped shell 49 and introduces it into the material through the jet nozzles 51. The jet nozzles 51 and the blades 50 can stir the material following the rotation of the disc-shaped shell 49. In addition, before the material is dried, it contains a large amount of moisture. Therefore, the air flow will not blow the material away, causing it to disperse and separate from the belt conveyor 14 inside the box body 1. In addition, even if the material is not in powder form, by controlling the wind speed of the drying air blowing component 3, it is also possible to prevent all the materials on the belt conveyor 14 from being blown away.

[0023] The drying air blowing component 3 includes a plurality of air guiding covers 10 fixedly connected inside the box body 1. The air guiding covers 10 are in an inverted convex shape. The air guiding covers 10 are provided with openings on both the side and the bottom passing through the box body 1. Each air guiding cover 10 corresponds to the upper side of a belt conveyor 14. A hot air blower 8 is fixedly connected to the surface of the box body 1. The output end of the hot air blower 8 is communicated with all the air guiding covers 10 through an air duct 9. A strip-shaped shell 16 is arranged above the track 46. The upper end of the fixed pipe 48 is rotatably communicated with the strip-shaped shell 16, and all the strip-shaped shells 16 are communicated with the air duct 9 through an air guiding hose 13.

[0024] The high-efficiency drying component 11 includes a T-shaped slide rail 28 with the same number as the belt conveyor 14. The T-shaped slide rail 28 is fixedly connected to the box body 1 along the length direction of the belt conveyor 14. A T-shaped slide bar 27 is slidably connected in the T-shaped slide rail 28. A rack 30 is fixedly connected to the T-shaped slide bar 27. A horizontal strip groove 29 is provided on the rack 30.

The movable end of the telescopic rod 33 is fixedly connected to the end of the T-shaped slide bar 27. A spring 34 is sleeved on the surface of the telescopic rod 33. The two ends of the spring 34 are respectively fixedly connected to the two ends of the telescopic rod 33. A plurality of polygonal rods 31 are equidistantly connected to the width direction of the belt conveyor 14 in the air guide cover 10.

A windshield 35 is fixedly connected to the top of the belt conveyor 14, and a plurality of fixed sleeves 38 are fixedly connected to the windshield 35 along a linear array. A lever 36 is slidably connected in the fixed sleeve 38. The lever 36 slides downward under the action of gravity and contacts the upper side of the belt conveyor 14. A pushing assembly 39 is arranged on the surface of the multi-faceted rod 31. The multi-faceted rod 31 rotates alternately forward and reversely while cooperating with the pushing assembly 39 to drive the sleeve 37 to move back and forth. The pushing assembly 39 includes a spring 2 41, an arc plate 1 42 and an arc plate 2 43. The arc plate 1 42 and the arc plate 2 43 are respectively fixedly connected to the inner wall of the wind guide cover 10 and the surface of the sleeve 37. The opposite surfaces of the arc plate 1 42 and the arc plate 2 43 are both arranged as inclined surfaces, and the directions of the two inclined surfaces are opposite to each other. A retaining ring 40 is fixedly connected to the multi-faceted rod 31 and the sleeve 37. A spring 2 41 is sleeved on the surface of the multi-faceted rod 31, and the two ends of the spring 2 41 are respectively in contact with the opposite surfaces of the two retaining rings 40. The reciprocating mechanism 2 cooperates with the telescopic rod 33 and the spring 1 34 to drive the rack 1 30 to move back and forth. The rack 1 30 cooperates with the gear 1 32, the multi-faceted rod 31 and the sleeve 37 to drive the windshield 35 to swing back and forth. Several windshields 35 can change the wind direction and make the airflow swing left and right, so that the entire upper surface of the belt conveyor 14 can be covered. The lever 36 can follow the windshield 35 to reciprocate and push away the material. The lever 36 can always be in contact with the material under the action of gravity. At the same time, the pushing component 39 can drive the sleeve 37 to move back and forth, so that the lever 36 pushes the material in an S shape. The lever 36 can be used to push the material away from several wavy boundaries, so that the high-temperature airflow can fully contact the material. The arc plate 2 43 rotates, and the arc plate 1 42 is stationary. With the cooperation of the two inclined surfaces, the arc plate 2 43 is gradually pushed away by the arc plate 1 42. At this time, the spring 2 41 is compressed. After the arc plate 1 42 is separated from the arc plate 2 43, the spring 2 41 pushes the sleeve 37 to return to its original position. The arc plate 1 42, the arc plate 2 43 and the spring 2 41 cooperate with each other to enable the sleeve 37 to reciprocate along the length direction of the polygonal rod 31.

[0025] The material breaking component 12 includes a material receiving housing 22, which is fixedly connected inside the box body 1. The upper side of the material receiving housing 22 is open and corresponds to one side of the belt conveyor 14. Two chutes 24 are fixedly connected to the opposite inner walls of the material receiving housing 22. A grille plate 23 is slidably connected between the two chutes 24. A rotating shaft 26 is rotatably connected inside the material receiving housing 22, and the rotating shaft 26 is located below the grille plate 23. A plurality of turning plates 25 distributed in a circular array are fixedly connected to the rotating shaft 26; The grille plate 23 reciprocates along with the reciprocating movement mechanism 2. When the material passes through the grille plate 23, it can be evenly dispersed, and the agglomerated blocks can also be broken up. When the material falls downward, it can push the turning plate 25 to rotate. During this process, the material will be rearranged, so that after the material falls onto the lower-layer belt conveyor 14, the undried part faces upward and can directly receive the airflow for drying.

[0026] A reciprocating movement mechanism 2 is fixedly connected to the surface of the box body 1, which is used to simultaneously drive the material breaking component 12, the high-efficiency drying component I 11, and the high-efficiency drying component II 15.

A pulley is arranged at the side wall of the strip-shaped groove 29, and the pulley corresponds to the arc surface of the arc-shaped top plate 17, which can reduce the kinetic energy lost due to friction; The power source of the reciprocating movement mechanism 2 is not limited to the cylinder 19, and can be replaced with an electric cylinder, a reciprocating motor, a crank and connecting rod reciprocating mechanism, etc. according to requirements. When the arc-shaped top plate 17 is inserted into the strip-shaped groove 29, it can push the first rack 30 to move. At this time, the first spring 34 is compressed. The arc-shaped top plate 17 moves along with the fixed frame 18 and disengages from the strip-shaped groove 29. The first spring 34 reversely pushes the first rack 30, enabling the first rack 30 to reciprocate.

[0027] With the above structure, the gypsum raw material to be dried is put into the feeding hopper 6 of the box body 1, and the raw material will fall onto the topmost belt conveyor 14. As the belt conveyor 14 operates, the raw material will fall from the topmost belt conveyor 14 to the lower-layer belt conveyor 14 one by one; By stacking multiple belt conveyors 14, the length of the device can be effectively reduced. At the same time, the time for the material to receive drying treatment is increased. And during the process of the material falling from the upper belt conveyor 14 to the lower belt conveyor 14, it passes through the dispersion assembly 12. The dispersion assembly 12 can disperse the agglomerated material, making the material more dispersed on the lower belt conveyor 14, improving the drying efficiency. And after the material falls onto the lower belt conveyor 14, it can be turned over, enabling the material that was not directly facing the high-temperature air flow originally to be directly dried; The drying air blowing assembly 3 is used to blow high-temperature air flow towards the material on the upper side of the belt conveyor 14. The first high-efficiency drying assembly 11 can guide the air flow, making the air flow swing back and forth and blow towards the upper side of the belt conveyor 14, enabling the high-temperature air flow to fully cover the belt conveyor 14. While guiding the air flow, the first high-efficiency drying assembly 11 can agitate the material on the surface of the belt conveyor 14. The first high-efficiency drying assembly 11 and the belt conveyor 14 cooperate to stir the material spread on the surface of the belt conveyor 14 into several wavy shapes, enabling the material to be in full contact with the high-temperature air flow. Through the second high-efficiency drying assembly 15, the material can be further stirred, and at the same time, the high-temperature air flow of the drying air blowing assembly 3 is introduced into the interior of the material.
