Description

Technical Field

[0001] The utility model relates to the technical field of kilns, and in particular to a bottom discharging mechanism of a vertical kiln. Background Art

[0002] As roasting processes and technologies continue to improve and perfect, vertical roasting kilns have also come into being. Vertical roasting kilns no longer have long kiln bodies like flat kilns, and there is no excessive building occupation. Vertical kilns use double-layer kiln bodies, which completely separate the combustion layer and the insulation layer. A fire channel is used between the two layers, and the raw materials are burned with a bottom fire. After the raw materials are burned through, they are unloaded to the insulation layer below for insulation. Vertical kilns require fewer skilled roasting technicians, and the output is 8-10 times greater than that of flat kilns with the same effective area. The kiln is equipped with a thermocouple, and the temperature can be directly observed by a temperature controller. It is a more feasible and ideal roasting kiln.

[0003] The application number in the existing public technology is: CN202021088014.0. An automatic unloading device for a light-fired kiln adopts a simple flat-push structure. Under the action of an external hydraulic cylinder or other driving force, it can realize the switching of the two states of blocking or discharging the discharge port, and realize the frequency and discharge amount of the unloading operation controlled by process parameters, thereby solving the problem of automatic unloading of the light-fired kiln. This structure is widely suitable for promotion and use in industrial kilns with vertical bottom discharge.

[0004] However, the above patent still has certain disadvantages when used: it uses a hydraulic cylinder to drive a push rod to move the material stop head, thereby realizing the sealing and discharging operation of the kiln. At this time, the high-temperature kiln will transfer heat to the material stop head, and transfer it to the push rod along the material stop head, and then transfer it to the hydraulic cylinder by the push rod. Long-term contact will cause the hydraulic cylinder and the push rod to be damaged due to high temperature, thereby affecting the normal operation and subsequent use of the structure, and in the process of back and forth friction, the material stop head is prone to wear, which will cause a gap between the top of the material stop head and the discharge port, thereby causing the flow of materials inside and outside the kiln when it is used, resulting in poor overall sealing effect and reducing the overall use effect.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model provides a bottom discharging mechanism for a vertical kiln, which has the following beneficial effects:

[0020] (1) The utility model adopts a first electromagnet, a second electromagnet, and a third electromagnet. During operation, the repulsive force generated by the operation of the first electromagnet at different positions can be used to perform a corresponding moving operation on the moving box, and then the repulsive force generated by the third electromagnet can be used to insert the blocking head into the discharge port to achieve a blocking operation. When the material is subsequently unloaded, the suction force generated by the second electromagnet can be used to adsorb and fix the moving rod at the bottom of the blocking head, thereby opening the discharge port.

[0021] (2) The utility model adopts a third electromagnet. After the moving box moves into place, the first electromagnet stops energizing and no magnetic force is generated, thereby ensuring that the moving box does not move. Then, the energized mutual repulsion of the third electromagnet on the top of the support seat inside the moving box can drive the blocking head as a whole to move upward under the action of repulsion, and then the whole head is inserted into the discharge port. Since the blocking head is sealed by entering and exiting the discharge port, it can still be effectively sealed when the top of the blocking head is worn, thereby ensuring the use effect of the vertical kiln furnace body and having the advantage of good sealing effect.

[0030] According to an embodiment of the utility model, a bottom discharging mechanism of a vertical kiln is provided.

[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, a bottom discharge mechanism of a vertical kiln according to an embodiment of the utility model comprises a vertical kiln body 1, fixed plates 4 are symmetrically installed at both sides of the bottom of the vertical kiln body 1, a bearing plate 7 is welded between the fixed plates 4, a moving box 10 is slidably connected to the top surface of the bearing plate 7, a support seat 18 is fixedly installed inside the moving box 10, a plurality of groups of first electromagnets 6 are symmetrically installed at the surface positions of the fixed plates 4 on both sides and the surface positions of the moving box 10 on both sides, an adsorption groove 12 is provided at the middle position of the top surface of the support seat 18, and the support seat The moving rod 3 is symmetrically and slidably connected to the two sides of the top of 18, and the second spring 20 is sleeved on the outer periphery of the bottom of the moving rod 3 and the inner top surface of the support seat 18, and the two ends of the second spring 20 are respectively fixed to the bottom surface of the moving rod 3 and the inner top surface of the support seat 18, and a blocking head 19 is fixedly installed at the top of the moving rod 3, and a third electromagnet 13 is installed at the bottom surface of the blocking head 19 and the inner position of the adsorption groove 12, and a second electromagnet 11 is installed at the bottom end of the moving box 10, and the second electromagnet 11 is located directly below the moving rod 3.

[0032] In one embodiment, ejection grooves 14 are symmetrically provided inside the carrier plate 7, one end of the ejection groove 14 is located inside the carrier plate 7 and an adjustment groove 8 is provided, the ejection groove 14 is slidably connected to a limit block 16, and one end of the limit block 16 passes through one side of the adjustment groove 8 and is slidably connected thereto, the bottom of the limit block 16 is located inside the ejection groove 14 and a first spring 15 is fixedly installed thereon, one side of the limit block 16 is located at the top position inside the adjustment groove 8 and is abutted against an electric push rod 9, the electric push rod 9 is arranged to drive the limit block 16 to move downward through its own operation when unloading is required, so that it can be disengaged from the limit groove 17, thereby ensuring that the moving box 10 can move smoothly, so that the bottom position of the unloading port 2 is exposed, which is convenient for unloading operation.

[0033] In one embodiment, limiting grooves 17 are symmetrically provided on both sides of the bottom of the moving box 10. The limiting grooves 17 are provided to cooperate with the limiting blocks 16, so as to limit and fix the moving box 10 after it is moved into place to prevent movement and ensure the sealing effect of the material blocking head 19 above.

[0034] In one embodiment, a discharge port 2 is provided in the middle of the bottom surface of the vertical kiln body 1. The size of the discharge port 2 is the same as that of the material blocking head 19. The size is set to ensure that the material blocking head 19 can smoothly block the discharge port 2, thereby ensuring that external substances will not invade during the firing process and internal heat will not leak out, thereby improving the use effect of the equipment.

[0035] In one embodiment, a controller 5 is fixedly installed on the surface of one side of the fixed plate 4. The controller 5 is configured to control the operation of multiple groups of internal electromagnets. Since the types of controllers 5 are diverse and the application technology is mature, they will not be described in detail. In order to ensure that multiple groups of electromagnets can smoothly generate the required repulsive or adsorption forces, the direction and line of the current used by each group of electromagnets can be set separately. This can avoid interference between each other and ensure that the equipment can be used normally.

[0036] In one embodiment, slopes are symmetrically provided on both sides of the bottom of the moving box 10 .

[0037] In one embodiment, the top of the limit block 16 is a trapezoidal structure, and the trapezoidal structure is set to cooperate with the slope at the bottom of the moving box 10. Through the mutual slope setting, the moving box 10 can be squeezed when it contacts the limit block 16, so that the limit block 16 can move down smoothly, and finally be ejected and reset under the drive of the first spring 15, thereby realizing the fixing operation of the moving box 10.

[0038] In one embodiment, a groove is provided between the mobile box 10 and the support seat 18 for inserting the material stop head 19. The groove is provided to facilitate the material stop head 19 to be received and adsorbed therein during unloading, thereby ensuring that the material stop head 19 does not protrude into the discharge port 2, thereby ensuring that the mobile box 10 can move smoothly from under the discharge port 2, so that the material inside can be discharged normally.

[0039] Working principle: In actual use, the vertical kiln body 1 can be used for normal firing operations. Before firing, the first electromagnet 6 on the surface of the fixed plate 4 on one side (when the two electromagnets change the polarity of the power supply, if the two electromagnet windings are connected in the same way, such as clockwise or counterclockwise windings, they will repel each other; if the two electromagnet windings are connected in different ways, one clockwise and the other counterclockwise, they will attract each other. Therefore, the two electromagnets can repel each other. In this application, the first electromagnet 6 and the third electromagnet 13 are provided with multiple groups, and the two groups are designed to repel each other) can push the moving box 10 to the middle position. At this time, the moving box 10 that moves due to the repulsive force can The limit block 16 protruding from the top of the plate 7 is squeezed, and as the moving box 10 continues to move, the limit groove 17 on its bottom surface will move to the upper position of the limit block 16. At this time, the limit block 16 loses the limit of squeezing, and the limit block 16 can be lifted upward as a whole through the deformation reset of the first spring 15 at its bottom, and then inserted into the limit groove 17, thereby realizing the fixed restriction operation of the moving box 10, so that it can accurately act on the position just below the discharge port 2, and the size of the moving box 10 is larger than the size of the opening opened by the two groups of supporting plates 7, so that it can ensure that the moving box 10 will not fall off from the opening when sliding on the surface of the supporting plate 7, thereby ensuring the safety of the structure, and the surface of the supporting plate 7 is also provided with a space for the moving box 1 0 movement, can further limit its movement trajectory and improve the movement effect. Then, after the moving box 10 moves into place, the first electromagnet 6 stops energizing, and no magnetic force is generated at this time, thereby ensuring that the moving box 10 does not move. Then, the energized mutual repulsion of the third electromagnet 13 on the top of the support seat 18 inside the moving box 10 can drive the blocking head 19 to move up as a whole under the action of repulsion, and then be inserted into the discharge port 2 as a whole. Since the blocking head 19 is blocked by entering and exiting the discharge port 2, it can still be effectively blocked when the top of the blocking head 19 is worn, thereby ensuring the use effect of the vertical kiln main body 1. Then, when discharging is required in the future, the third electromagnet is used to 13 is powered off and the second electromagnet 11 is turned on. At this time, the stopper head 19 loses the support of the repulsive force and falls under the deformation reset of the second spring 20 and its own weight, and the moving rod 3 at the bottom is made of a material that can be adsorbed by a magnet, such as iron, so that the moving rod 3 can be adsorbed when it falls, thereby ensuring that the stopper head 19 can be adsorbed and fixed inside the adsorption groove 12 when it falls to the bottom, so that the stopper head 19 will not remain in the internal position of the discharge port 2, ensuring that it can move smoothly in the future, and then turn on the first electromagnet 6 on the other side to generate repulsive force, so that the moving box 10 shows a tendency to move as a whole, and then the electric push rod 9 can be ejected to drive the limit block 16 to move downward as a whole.At this time, the limit block 16 can be moved out of the limit groove 17. At this time, under the action of repulsion, the mobile box 10 can be smoothly moved out, so that the bottom of the discharge port 2 is open to realize the discharge operation. During the overall operation, the suction and repulsion of multiple sets of electromagnets are used to realize the operation between the structures, avoiding the heat contact transfer between the components, which can improve the safety of the corresponding equipment, reduce the problem of high temperature damage to the equipment caused by heat transfer, and improve the overall use effect. The device as a whole has the advantages of heat conduction blocking, equipment heat damage prevention, and good blocking effect.
