Description

Technical Field

[0001] The invention relates to the technical field of desulfurizing agent drying, in particular to a desulfurizing agent drying device and a use method thereof. Background Art

[0002] Desulfurizer refers to a class of chemicals or materials used to remove sulfides in various industrial processes. The production and processing procedures of desulfurizers vary depending on the raw materials and technical routes used. Taking the common calcium-based desulfurizer as an example, such as limestone as the raw material, its basic production and processing procedures include raw material calcination, raw material cooling, grinding and mixing, granulation, drying and packaging and storage. When drying the desulfurizer, drying equipment such as a belt dryer is required. The belt dryer is a continuously working drying equipment that realizes heat exchange of the material in the reverse heat flow by transferring the material to the transmission mesh belts arranged in layers, thereby achieving a drying effect.

[0003] For example, a mesh belt dryer disclosed in the patent with the current announcement number CN103486836A includes a chassis, a shunt pipe is provided at the top of the side wall of the chassis along the horizontal extension direction of the side wall, the shunt pipe is provided with a hot air inlet and a plurality of hot air outlets evenly distributed on the shunt pipe along the axial direction of the shunt pipe, each of the hot air outlets is connected to a vertical hot air channel, and the lower end of each vertical hot air channel is located at the bottom of the chassis and communicates with the interior of the chassis. The hot air outlets are evenly arranged on the shunt pipe, so the vertical hot air channels are also evenly distributed, so the hot air transported by the bottom of the vertical hot air channel is relatively uniform, so that the temperature distribution at the same horizontal height in the chassis is uniform, ensuring that the grain on the conveyor mesh belt is evenly heated, and has a good drying effect. The mesh belt dryer has the advantages of scientific design, uniform hot air distribution, and good drying effect.

[0004] Although the above device solves the problem of uneven drying, it still has the following shortcomings: As the heat source in the drying box rises from bottom to top, the conveyor belts are multi-layered and each conveyor belt is double-layered. The material is located on the top surface. As the hot air gradually rises from the bottom to the top, it will be blocked once by the bottom of each conveyor belt. Although the mesh conveyor belt has mesh, it will also block part of the hot air. When part of the heat source is blocked, the heat exchange efficiency of the upper material will be poor. Although the mesh belt can transfer the material to the bottom layer, this will also cause the problem of extending the drying time, further reducing the drying efficiency. Summary of the invention

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-Figure 10 A desulfurizing agent drying device comprises a dryer body 1, a feeding unit 2 connected to one side of the dryer body 1, a heating unit 13 connected to the inner side of the bottom of the dryer body 1 and a multi-layer conveying structure connected to the dryer body 1, wherein the multi-layer conveying structure comprises a plurality of conveying mesh belts, each of which comprises a chain 3 symmetrically arranged on both sides and a plurality of rollers 22 connected to the chain 3, a fixed shaft 28 is fixedly connected between two symmetrically arranged rollers 22, a sleeve 29 is sleeved on the outer side of the fixed shaft 28, and two symmetrically arranged clamping grooves 30 are provided on the top of the sleeve 29, one of which is clamped A rotating mesh belt 16 is fixedly connected to the groove 30, and the other end of the rotating mesh belt 16 is overlapped with the clamping groove 30 on the adjacent sleeve 29. The rotation direction of the multiple rotating mesh belts 16 corresponds to the transmission direction of the conveyor mesh belt. The inner sides of both ends of the chains 3 on both sides of each conveyor mesh belt are meshed and connected with the first gear shaft 14 and the second gear shaft 15. A motor 19 is installed on the back of the dryer body 1, and the output end of the motor 19 is fixedly connected to the rotating shaft 20. One end of the rotating shaft 20 passes through the dryer body 1 and is fixedly connected to the first gear shaft 14. A blocking component is provided at the end of each layer of the conveyor mesh belt in the conveying direction.

[0024] The desulfurizer drying equipment of the present invention starts the dryer body 1 when the desulfurizer needs to be dried, so that the feeding unit 2 and the heating unit 13 work, and the desulfurizer (hereinafter referred to as the material) enters the first layer of conveyor mesh belt through the feeding unit 2. The first layer of conveyor mesh belt transfers the material to the end and allows the material to naturally fall to the second layer of conveyor mesh belt. The material on the upper layer will naturally fall to the lower layer, and is dried in the process and transferred out of the dryer body 1. Figure 2 As shown, when the rotating mesh belt 16 is meshed and transmitted by the second gear shaft 15 after passing through the chain 3, the rotating mesh belt 16 is transmitted from the top surface to the bottom surface. Under the action of gravity, the rotating mesh belt 16 that rotates to the bottom surface will drive the sleeve 29 to rotate outside the fixed shaft 28 between the two rollers 22. At this time, one of the sleeves 29 rotates under the action of the rotating mesh belt 16, so that the end of the rotating mesh belt 16 is separated from the clamping groove 30 on the outer wall of the other sleeve 29. At this time, the multiple rotating mesh belts 16 located on the bottom surface of the conveyor mesh belt are all in a vertical state. When the rotating mesh belt 16 passes one end of the first gear shaft 14, that is, it rotates upward and reciprocates, it will automatically return to a flat state when it rotates to the top surface under the rotation of the sleeve 29, and the end of the rotating mesh belt 16 will overlap with the clamping groove 30 on the other sleeve 29. The top surface of each layer of conveyor mesh belt is always in a flat state, receiving the transmission and drying of materials, and the multiple rotating mesh belts 16 on the bottom are all in a vertically open state. At this time, a cavity is formed between each rotating mesh belt 16, so that the heat source can be directed upward without obstruction, thereby achieving high heat exchange efficiency.

[0025] The rotating mesh belt 16 on each layer of the conveyor mesh belt should rotate in the same direction as the transmission direction to ensure that the rotating mesh belt 16 rotates smoothly.

[0026] By modularizing the original conveyor mesh belt, and utilizing the cooperation of the fixed shaft 28, the sleeve 29, the rotating mesh belt 16 and the clamping groove 30, the top surface of the conveyor mesh belt can remain horizontal to receive the conveyed materials, and the multiple rotating mesh belts 16 rotated to the bottom surface are opened under the action of gravity and are in a vertical state, thereby forming cavities between the multiple rotating mesh belts 16. The multiple cavities can facilitate the unimpeded passage of the heat source, so that the heat source can directly exchange heat with the material contact surface, thereby accelerating the time for the heat source to be transmitted upward. This design can achieve good heat exchange effect, high drying efficiency, and reduce drying time.

[0027] As a preferred technical solution of the present invention, the blocking assembly includes a baffle 12, the back of the baffle 12 is fixedly connected to a mounting rod 17, the mounting rod 17 is connected to the inner wall of the dryer body 1, the back side of the baffle 12 is connected to a collecting piece, and the front side of the baffle 12 is connected to a limiting piece.

[0028] Specifically, when the upper material is transmitted to the lower layer through the upper conveyor mesh belt, in order to prevent the material from splashing into the box of the dryer body 1, the baffle 12 will receive the material. When the baffle 12 contacts the material, since the baffle 12 is arranged in an arc shape as a whole and is located above the lower conveyor mesh belt, the material will slide from the inner wall of the baffle 12 to the lower conveyor mesh belt, which can effectively prevent the material from spilling.

[0029] As a preferred technical solution of the present invention, the collecting part includes a dust accumulation plate 25, which is fixedly connected to the back side of the baffle 12, and a collecting chamber 34 is opened in the dust accumulation plate 25. A sieve hole 24 is opened on the baffle 12. A fan mechanism is fixedly connected to the back of the dryer body 1, and the fan mechanism includes a suction fan 7. The front end of the suction fan 7 is fixedly connected to a plurality of pipes 6, and the ends of the plurality of pipes 6 are fixedly connected to sealing tubes 26. A through groove 33 is opened on the outer wall of the box body of the dryer body 1. The sealing tube 26 is sealed and connected in the through groove 33 and is connected to the collecting chamber 34 of the dust accumulation plate 25. The dust accumulation plate 25 is inclined and has a bell-mouth cross-section. A recovery box 8 is fixedly connected to the end of the suction fan 7 away from the pipe 6.

[0030] Specifically, when the material contacts the baffle 12, since the desulfurizer uses limestone as raw material, dust will be generated when the material falls from the upper layer to the lower layer. At this time, the mesh holes 24 on the baffle 12 can play a certain degree of filtering effect. The filtered dust will directly pass through the mesh holes 24 and fall directly into the collection chamber 34 in the dust accumulation plate 25. When the dust accumulates to a certain extent, the suction fan 7 can be started to make the suction fan 7 work and suck it out through the pipe 6 into the recovery box 8, which is convenient for subsequent dust recovery and cleaning.

[0031] By setting the screen holes 24 on the baffle 12, the dust in the material can be filtered to a certain extent when the material passes through the baffle 12. The filtered dust is collected by the collection chamber 34 in the dust accumulation plate 25. When the dust accumulates to a certain extent, the dust can be sucked out and collected by the suction fan 7.

[0032] As a preferred technical solution of the present invention, the limiting member includes an arc-shaped piece 18, the inner wall of the arc-shaped piece 18 is infinitely close to the rotating mesh belt 16 of the conveyor mesh belt, the outer wall of the arc-shaped piece 18 is fixedly connected to a connecting rod 27, and the end of the connecting rod 27 is installed with a telescopic member connected to the baffle 12.

[0033] Specifically, when the desulfurizer naturally falls from the end of the upper conveyor mesh belt to the upper surface of the lower conveyor mesh belt, the inner wall of the arc-shaped sheet 18 will be infinitely close to the rotating mesh belt 16. This arrangement allows the arc-shaped sheet 18 to limit the rotating mesh belt 16, so that the rotating mesh belt 16 can rotate smoothly without directly flipping, which would prevent the material from falling smoothly to the lower conveyor mesh belt.

[0034] As a preferred technical solution of the present invention, the telescopic member includes a horizontal plate 35, a horizontal groove 36 is opened in the horizontal plate 35, a movable groove 37 connected to the horizontal groove 36 is opened on the top surface of the horizontal plate 35, the connecting rod 27 is slidably connected in the horizontal groove 36, a threaded rod 38 fixedly connected to the top surface of the connecting rod 27 is slidably connected in the movable groove 37, a threaded ring 39 is threadedly connected to the outer side of the top of the threaded rod 38, the bottom surface of the threaded ring 39 is abutted against the top surface of the horizontal plate 35, and the outer wall of the threaded ring 39 is fixedly connected to the support rod 40.

[0035] Specifically, in order to make the telescopic position of the arc piece 18 adjustable at any time, the connecting rod 27 on the back of the arc piece 18 can be inserted into the transverse groove 36 in the transverse plate 35, and at the same time drive the threaded rod 38 to slide into the movable groove 37. The sliding of the connecting rod 27 and the transverse plate 35 can make the arc piece 18 easy to install and adjust, and the threaded ring 39 can threadably connect the threaded rod 38 to fix the connecting rod 27 in the transverse plate 35, thereby ensuring the fixed position of the arc piece 18 after adjustment; the setting of the support rod 40 can facilitate the rotation of the threaded ring 39.

[0036] As a preferred technical solution of the present invention, conveyor belt mounting plates 11 are installed on both sides of each conveyor mesh belt, and the conveyor belt mounting plates 11 are fixedly connected to the inner wall of the dryer body 1. A loading port 23 corresponding to the loading unit 2 is opened on the top of the dryer body 1, and a plurality of operating ports 4 are opened on the side of the dryer body 1 away from the motor 19. An operating door 5 is hingedly provided on the operating port 4. One end of the dryer body 1 away from the loading unit 2 is fixedly connected to two discharge side panels 10, and the bottom conveyor mesh belt is fixedly installed in the two discharge side panels 10.

[0037] Specifically, the arrangement of the conveyor belt mounting plate 11 is inherently provided and is for the convenience of installing the conveyor belt; When the material needs to be transported and dried, it enters the loading port 23 through the loading unit 2 and enters the first layer of the conveyor belt for drying; the setting of the operating port 4 is to facilitate opening the operating door 5 to inspect and maintain the conveyor belt; the operating door 5 should be sealed and closed between the operating port 4, so as to reduce the probability of heat dissipation.

[0038] As a preferred technical solution of the present invention, a second mounting plate 21 is fixedly installed at the bottom of the motor 19, and a first mounting plate 9 is fixedly installed at the bottom of the suction fan 7. The first mounting plate 9 and the second mounting plate 21 are both fixedly connected to the outer wall of the dryer body 1.

[0039] Specifically, by using the coordinated arrangement of the second mounting plate 21 and the first mounting plate 9 , the motor 19 and the suction fan 7 can be installed and fixed on the outer wall of the dryer body 1 .

[0040] As a preferred technical solution of the present invention, a slider 31 is fixedly connected to the end of the mounting rod 17 , and a slide groove 32 corresponding to the position of the slider 31 is formed on the inner wall of the dryer body 1 .

[0041] Specifically, when the baffle 12 needs to be installed or removed, the slider 31 can be slid so that the slider 31 drives the installation rod 17 and the baffle 12 to move out of the slide groove 32, that is, out of the dryer body 1, so as to facilitate the installation and adjustment of the baffle 12.

[0042] Among them, the above-mentioned motor 19 and suction fan 7 are both existing mature technologies and have been fully disclosed, so they are not fully described in the specification; the power supplies of the motor 19 and the suction fan 7 should be equipped with power connection cables, and they are electrically connected to the external main controller and 220V phase voltage through the power lines, and the main controller can be a conventional known device such as a computer that plays a control role.

[0043] In addition, the chain 3, the roller 22 and the fixed shaft 28 are driven and transmitted by the gear shaft, which is also basically similar to the existing mesh belt conveyor structure, so no further details will be given here.

[0044] A method for using a desulfurizing agent drying device comprises the following steps: Step 1: Start the dryer body 1, the multi-layer conveyor belt on the dryer body 1 starts to run, and the feeding unit 2 and the heating unit 13 work at the same time. The granular desulfurizer enters the first layer of conveyor mesh belt through the feeding port 23. When the first layer of conveyor mesh belt conveys the desulfurizer to the end, the desulfurizer naturally falls into the second layer of conveyor mesh belt, and the multiple rotating mesh belts 16 on the conveyor mesh belt rotate at the same time.

[0045] Step 2: When the rotating mesh belt 16 rotates from the top surface of the conveyed material to the bottom surface, the sleeve 29 outside the fixed shaft 28 between the two rollers 22 drives the rotating mesh belt 16 to rotate, and rotates to a vertical state due to gravity.

[0046] Step 3: When the desulfurizer naturally falls from the end of the upper conveyor mesh belt to the upper surface of the lower conveyor mesh belt, the baffle 12 remains stationary; at the same time, the sieve holes 24 on the baffle 12 cooperate with the collection cavity 34 in the dust accumulation plate 25 to collect the dust.

[0047] Step 4: When the dust is collected to a certain extent, the suction fan 7 can be started, and the suction fan 7 collects the dust into the recovery box 8 through the pipeline 6.

[0048] Step 5: When the desulfurizer naturally falls from the end of the upper conveyor mesh belt to the upper surface of the lower conveyor mesh belt, the inner wall of the arc sheet 18 will be infinitely close to the rotating mesh belt 16, so that the rotating mesh belt 16 rotated to the end can smoothly rotate to the lower surface.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

A loading port (23) corresponding to the loading unit (2) is provided on the top of the dryer body (1). A plurality of operating ports (4) are provided on a side of the dryer body (1) away from the motor (19), and an operating door (5) is hingedly provided on the operating port (4). One end of the dryer body (1) away from the loading unit (2) is fixedly connected to two discharge side plates (10), and the conveyor mesh belt at the bottom layer is fixedly installed in the two discharge side plates (10).

7. The desulfurizing agent drying equipment according to claim 1, characterized in that: A second mounting plate (21) is fixedly mounted on the bottom of the motor (19), a first mounting plate (9) is fixedly mounted on the bottom of the suction fan (7), and both the first mounting plate (9) and the second mounting plate (21) are fixedly connected to the outer wall of the dryer body (1).

8. The desulfurizing agent drying equipment according to claim 2, characterized in that: The end of the mounting rod (17) is fixedly connected to a sliding block (31), and the inner wall of the dryer body (1) is provided with a sliding groove (32) corresponding to the position of the sliding block (31).

9. A method for using a desulfurizing agent drying device, comprising the following steps: Step 1: Start the dryer body (1), the multi-layer conveyor belt on the dryer body (1) starts to run, and the feeding unit (2) and the heating unit (13) work at the same time, and the granular desulfurizer enters the first layer of conveyor mesh belt through the feeding port (23). When the first layer of conveyor mesh belt conveys the desulfurizer to the end, the desulfurizer naturally falls into the second layer of conveyor mesh belt, and at the same time, the multiple rotating mesh belts (16) on the conveyor mesh belt rotate; Step 2: When the rotating mesh belt (16) rotates from the top surface of the conveyed material to the bottom surface, the sleeve (29) outside the fixed shaft (28) between the two rollers (22) drives the rotating mesh belt (16) to rotate, and rotates to a vertical state due to the action of gravity; Step 3: When the desulfurizer naturally falls from the end of the upper conveyor mesh belt to the upper surface of the lower conveyor mesh belt, the baffle (12) remains stationary; at the same time, the sieve holes (24) on the baffle (12) cooperate with the collection cavity (34) in the dust accumulation plate (25) to collect dust; Step 4: When the dust has been collected to a certain extent, the suction fan (7) can be started, and the suction fan (7) collects the dust into the recovery box (8) through the pipeline (6); Step 5: When the desulfurizer naturally falls from the end of the upper conveyor mesh belt to the upper surface of the lower conveyor mesh belt, the inner wall of the arc-shaped sheet (18) will be infinitely close to the rotating mesh belt (16), so that the rotating mesh belt (16) that has rotated to the end can smoothly rotate to the lower surface.
