Description

Technical Field

[0001] This utility model relates to the technical field of equipment for kiln maintenance, and in particular to a kiln mechanical maintenance tool. Background Technology

[0002] Sand sealing troughs are set at the bottom of both sides of the kiln. The length of the sand sealing troughs is set along the length of the kiln. The sand sealing troughs are filled with sand, which can effectively prevent air leakage and heat loss at the bottom of both sides of the kiln. As the kiln is used, impurities generated during the firing process may enter the sand sealing troughs. The impurities mix with the sand and reduce the sealing effect of the sand sealing troughs.

[0003] The patent document with publication number "CN218223385U" discloses a kiln maintenance tool that uses a motor to drive a screening machine to screen sand and impurities, thereby improving the screening effect of sand.

[0004] The above-mentioned documents require additional motors and power supplies, which consumes more energy. Furthermore, the sand needs to be screened during maintenance, and the sand can only be refilled into the sand sealing trough after screening. This requires a long waiting time for the screening to be completed, which affects the normal operation of the kiln. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the prior art: the above-mentioned documents require additional motors and power supplies, which consumes more energy, and the sand needs to be screened during maintenance. After the screening is completed, the sand can be refilled into the sand sealing trough, which requires a long time to wait for the screening to be completed, affecting the normal use of the kiln. Therefore, a kiln mechanical maintenance tool is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A kiln mechanical maintenance tool includes a kiln body and a housing disposed on the ground, the housing being disposed below the kiln body;

[0008] An adjustment mechanism is provided inside the housing. The adjustment mechanism includes a sealing box, a sealing block, a fixing column, an L-shaped plate, and an inclined plate. The sealing box is fixedly connected to the side wall of the housing. An air outlet is opened on the lower end face of the sealing box. The sealing block is slidably connected to the inner side wall of the sealing box. The fixing column is fixedly connected to the end of the sealing block near the housing. The sliding rod is fixedly connected to the end of the fixing column near the housing. The L-shaped plate is fixedly connected to the end of the sliding rod away from the fixing column. The inclined plate is fixedly connected to the inner side wall of the sealing box. The L-shaped plate and the inclined plate are slidably connected. Both the side walls of the L-shaped plate and the inclined plate have discharge ports.

[0009] Preferably, mounting blocks are fixedly connected to both ends of the inner sidewall of the housing, and limit rods are slidably connected to the sidewalls of the two mounting blocks, with a screen fixedly connected to the upper end face of the limit rods.

[0010] Preferably, the sidewall of the fixed column is fixedly connected with round rods in a ring array, and the sidewall of the sealing box is fixedly connected with a limiting ring, and the round rods are slidably connected to the limiting ring.

[0011] Preferably, the upper surface of the screen is equipped with a plurality of triangular blocks in a linear array, the L-shaped plate is slidably connected to the triangular blocks, and an impact head is fixedly connected to the side wall of the L-shaped plate, the impact head being slidably connected to the housing.

[0012] Preferably, a water storage ring is fixedly connected to the side wall of the furnace body, and a conduit is fixedly connected between the water storage ring and the sealing box.

[0013] Preferably, a return spring is fixedly connected between the fixed column and the sealing box, and a vibration spring is fixedly connected between the mounting block and the screen.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By circulating and sieving two portions of sand alternately, when the sand in the sand sealing trough contains a large number of impurities and leaks air, it can be directly replaced with the sieved sand. There is no need to wait for the sand to be sieved and then resealed. The furnace can continue to fire, saving a lot of sieving time. There is no need to interrupt the firing of the furnace to sieve the sand, which improves the firing efficiency.

[0016] 2. The energy released from the furnace opening during firing heats the water, generating steam that drives the sealing block to move. In conjunction with the round rod and the limiting ring, the sealing block can move a longer distance, causing the L-shaped plate to release sand in a measured amount and driving the screen to sieve it. The sand is sieved using the energy lost from the furnace itself, requiring no additional energy supply, making it more energy-efficient and environmentally friendly. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0024] Reference Figures 1-4 A kiln mechanical maintenance tool includes a kiln body 2 and a shell 1 set on the ground. The shell 1 is set below the kiln body 2, and the kiln body 2 is fixed in the factory or other workplace by a simple support frame.

[0025] An adjustment mechanism is provided inside the housing 1. The adjustment mechanism includes a sealing box 3, a sealing block 4, a fixing post 5, an L-shaped plate 7, and an inclined plate 8. The sealing box 3 is fixedly connected to the side wall of the housing 1, and an air outlet is opened on the lower end face of the sealing box 3. The sealing block 4 is slidably connected to the inner side wall of the sealing box 3. The fixing post 5 is fixedly connected to the end of the sealing block 4 near the housing 1. A return spring 18 is fixedly connected between the fixing post 5 and the sealing box 3. A slide rod 6 is fixedly connected to the end of the fixing post 5 near the housing 1. The L-shaped plate 7 is fixedly connected to... Connected to the end of the slide rod 6 away from the fixed column 5, the inclined plate 8 is fixedly connected to the inner wall of the sealing box 3. The L-shaped plate 7 is slidably connected to the inclined plate 8. Both the L-shaped plate 7 and the inclined plate 8 have discharge ports on their side walls. The discharge ports are set to be small, so less sand flows out at a time, avoiding accumulation on the screen 11. The inclined plate 8 is set at an inclination and has a relatively smooth inner wall, which makes it easy for sand to slide down. At the same time, it and the shell 1 enclose a storage container. The inclined plate 8 stores a portion of sand equal to that in the sand sealing groove, which is used to replace it.

[0026] Mounting blocks 9 are fixedly connected to both ends of the inner sidewall of the housing 1. Limiting rods 10 are slidably connected to the sidewalls of the two mounting blocks 9. A screen 11 is fixedly connected to the upper end face of the limiting rod 10. The edge of the screen 11 is a rigid fixed edge. A vibration spring 19 is fixedly connected between the mounting blocks 9 and the screen 11.

[0027] A circular array of round rods 12 are fixedly connected to the side wall of the fixed column 5. The round rods 12 are made of highly elastic material and will bend and deform when subjected to a certain external force. They will quickly return to their shape after the external force is removed. A limiting ring 13 is fixedly connected to the side wall of the sealing box 3. The round rods 12 are slidably connected to the limiting ring 13. Multiple triangular blocks 14 are installed in a linear array on the upper end face of the screen 11. The L-shaped plate 7 is slidably connected to the triangular blocks 14. An impact head 15 is fixedly connected to the side wall of the L-shaped plate 7. The impact head 15 is made of highly elastic material such as rubber to avoid damage to the device during impact. The impact head 15 is slidably connected to the shell 1.

[0028] A water storage ring 16 is fixedly connected to the side wall of the furnace body 2. The water storage ring 16 is hollow inside and connected to an external water pipe. The water storage ring 16 is located at the furnace opening and is made of heat-resistant and heat-conducting material. A conduit 17 is fixedly connected between the water storage ring 16 and the sealing box 3.

[0029] In this invention, during routine firing, the heat escaping from the furnace opening of the furnace body 2 heats the water in the water storage ring 16, generating steam. The steam enters the sealing box 3 through the conduit 17. As the pressure increases, it continuously pushes the sealing block 4 to move and compresses the return spring 18. The sealing block 4 drives the fixed column 5 and the sliding rod 6 to move. The fixed column 5 drives the round rod 12 to move. The round rod 12 is limited by the limiting ring 13 and cannot move forward. The pressure continues to increase until it is sufficient to bend and deform the round rod 12. After the round rod 12 passes the limiting ring 13, it quickly returns to its shape. The round rod 12 is again limited by the limiting ring 13. At this time, the sealing block 4 is no longer sealing the air outlet, and the high-pressure steam flows out from the air outlet. The sliding rod 6 moves to push the L-shaped plate 7. At this time, the discharge port on the L-shaped plate 7 coincides with the discharge port on the inclined plate 8. The sand stored in the inclined plate 8 slowly flows out from the discharge port onto the screen 11. When the steam continues to flow out, the pressure decreases to the point where the return spring 18 minus the steam pressure is sufficient to bend and deform the round rod 12. The round rod 12 passes the limiting ring 13, and the sealing block 4 is reset under the elastic force of the return spring 18. Sand no longer flows out of the discharge port. Because the discharge port is relatively small, the amount of sand flowing out at one time is also small. The resetting of the sealing block 4 causes the fixed column 5 and slide rod 6 to reset. The slide rod 6 then causes the L-shaped plate 7 to reset. When the L-shaped plate 7 contacts the triangular block 14, it squeezes the triangular block 14. Combined with the vibration spring 19, the squeezing of the triangular block 14 causes the screen 11 and the limiting rod 10 to vibrate up and down, thus sieving the sand. The L-shaped plate 7 causes the impact head 15 to strike the housing 1. Under the action of vibration and shaking, a small amount of sand is fully sieved on the screen 11, while the sand accumulated in the inclined plate 8 is... Under the action of vibration, the sand will gather near the discharge port. As the furnace body 2 runs, the sand is continuously and evenly screened into the shell 1. When a lot of impurities enter the sand sealing trough in the furnace body 2 and the sand inside needs to be screened and replaced, the sand screened by the shell 1 is directly used to replace the sand in the sand sealing trough. The sand containing impurities is poured into the inclined plate 8, and the furnace body 2 can continue to fire. The furnace body 2 automatically screens the sand containing impurities in the inclined plate 8 during firing, saving a lot of screening time. There is no need to interrupt the firing of the furnace body 2 to screen the sand, which improves the firing efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
