Description

Technical Field

[0001] The invention relates to the field of kiln replacement chambers, and in particular to a novel industrial kiln replacement chamber with an elastic buffer mechanism. Background Art

[0002] A kiln is a furnace used to fire ceramics, sculptures, or fuse enamel to the surface of metal objects. It is usually made of bricks and stones, and can be made into various sizes. It can be operated by combustible gas, oil or electricity. Electric kilns are easier to control temperature than kilns using combustible gas and oil. The temperature in the kiln is measured by a pyrometer or a temperature cone, which can be seen through a peephole. The kiln usually consists of four parts: the kiln chamber, combustion equipment, ventilation equipment, and conveying equipment. Electric kilns mostly use electric furnace wires, silicon carbon rods or molybdenum disilicide as heating elements. Their structure is relatively simple and easy to operate.

[0003] The kiln car is the transportation equipment of the tunnel kiln. When working, it has to bear the gravity of the items on the car (including lining bricks and material stacks) and the thrust of the car pusher. The kiln car has a high working temperature and has to withstand repeated temperature changes. Therefore, the kiln car should have sufficient strength and heat resistance. The kiln car and the curved seal are two indispensable components of the tunnel kiln. The kiln car is responsible for transporting materials, while the curved seal is responsible for maintaining the temperature and atmosphere in the kiln stable.

[0004] The kiln's displacement chamber is a device used for gas displacement, mainly used for atmosphere control and gas exchange in the kiln. It is usually located at both ends of the kiln to ensure sufficient process atmosphere concentration in the kiln. The sealing of the displacement chamber plays a vital role in ensuring the concentration of the process atmosphere. To ensure the sealing of the displacement chamber, the sealing of the gate of the displacement chamber is the top priority. After the kiln car enters the displacement chamber, the displacement chamber is closed, and after the internal gas is replaced with a protective atmosphere, the gate on the other side of the displacement chamber is opened, and the kiln car in the displacement chamber is pushed into the kiln.

[0005] Chinese patent application CN103292596A discloses an atmosphere replacement chamber sealing door mechanism, including an atmosphere replacement chamber, a first sealing door is provided on one side of the atmosphere replacement chamber, and two side surfaces adjacent to the side surface are respectively provided with a second sealing door and a push plate; the first and second sealing doors respectively include two slide rails, four sliders, a door panel and a first driving device for driving the door panel to move up and down; the door panel is vertically arranged, the first driving device is located above the door panel, the two slide rails are vertically arranged and arranged on both sides of the door panel, the four sliders are arranged in groups of two on two vertical sides of the door panel, and the sliders and the slide rails cooperate with each other; the push plate is vertically arranged, and the push plate is equipped with a second driving device for driving its translational movement, which can seal and isolate the furnace space of the push plate furnace from the outside world, thereby improving the quality of the product;

[0006] Chinese patent application CN117268097A discloses an airtight replacement chamber device for a push plate kiln, which improves airtightness through a first airtight replacement chamber and a second airtight replacement chamber. Sealing strips are provided around the closed door, and the sealing strips are fitted to the inside of the first airtight replacement chamber to form a closed space, thereby improving the airtightness of the first airtight replacement chamber and ensuring that the first airtight replacement chamber and the second airtight replacement chamber are always kept one open and the other closed. At the same time, a first pulling mechanism is used to quickly pull the sagger to meet the needs of efficient production.

[0007] The above patent application and prior art also have the following defects:

[0008] The internal temperature of the existing kiln is relatively high, and it is impossible to install driving components such as motors and hydraulic rods inside. The kiln cart needs to be pushed into the kiln by an external driver. The kiln carts are pushed into the kiln one by one. The kiln carts that are close to each other can block the flame in the kiln from directly rushing to the bottom of the kiln cart and protect the walking structure at the bottom of the kiln cart. However, when the kiln carts that are close to each other enter the replacement chamber, there is no gap between them, which makes the replacement chamber unable to be sealed, or the gate needs to be offset against the kiln car, resulting in poor sealing effect. External driving components also need to extend into the replacement chamber, resulting in poor sealing effect between the replacement chamber and the outside world, and the protective atmosphere in the replacement chamber and the kiln is prone to leakage, affecting the firing and heat treatment effects of the product.

[0009] Therefore, the present application provides a novel industrial kiln replacement chamber with an elastic buffer mechanism to meet the demand. Summary of the invention

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1: Reference Figure 1-Figure 15 A novel industrial kiln replacement chamber with an elastic buffer mechanism is shown, comprising a kiln 1, a kiln car 2 is arranged in the kiln 1, a replacement chamber 3 is arranged at one end of the kiln 1, closing components 4 are arranged on both sides of the replacement chamber 3, the closing components 4 can close both sides of the replacement chamber 3, and a pushing component 5 is also arranged in the replacement chamber 3, and the pushing component 5 can push the kiln car 2 in the replacement chamber 3 into the kiln 1;

[0046] The pushing assembly 5 includes a plurality of pushing units 6, and the pushing unit 6 includes a track plate 61 and a pushing block 62. The track plate 61 is provided with a shallow groove 611, a deep groove 612, a switching groove 613 and an inclined groove 614. The shallow groove 611, the switching groove 613, the deep groove 612 and the inclined groove 614 are connected end to end to each other, and the pushing block 62 can circulate and move along the shallow groove 611, the switching groove 613, the deep groove 612 and the inclined groove 614.

[0047] When the pushing block 62 moves along the shallow groove 611 , the pushing block 62 can abut against the kiln car 2 and push the kiln car 2 to move; when the pushing block 62 moves along the deep groove 612 , the pushing block 62 moves under the kiln car 2 .

[0048] The top of the replacement chamber 3 is connected with an exhaust pipe and an air inlet pipe. The exhaust pipe is connected with an exhaust pump for discharging the gas in the replacement chamber 3 . The air inlet pipe is connected with an air inlet pump for introducing the protective gas into the replacement chamber 3 .

[0049] The closing component 4 seals the replacement chamber 3 and the kiln 1, opens the other end of the replacement chamber 3, places the product on the kiln car 2, and pushes it into the replacement chamber 3. The closing component 4 seals both ends of the replacement chamber 3, and the exhaust pipe exhausts the gas in the replacement chamber 3. Then, the air inlet pipe passes the protective gas into the replacement chamber 3. Then, the closing component 4 releases the seal between the replacement chamber 3 and the kiln 1. Then, the pushing unit 6 drives the kiln car 2 in the replacement chamber 3 and the kiln 1 to move. When the pushing unit 6 drives the kiln car 2 to move, the pushing block 62 moves along the shallow groove 611, and the pushing block 62 and the kiln The kiln car 2 is pushed against and moved by the kiln car 2, and the kiln car 2 in the replacement chamber 3 is pushed into the kiln furnace 1. The pushing block 62 moves from the shallow groove 611 to the switching groove 613, and moves with the switching groove 613 to the deep groove 612. Then the pushing block 62 moves in the opposite direction. Due to the height difference between the bottom of the deep groove 612 and the switching groove 613, the pushing block 62 cannot move into the switching groove 613, and thus moves in the opposite direction in the deep groove 612. The height of the pushing block 62 decreases and cannot contact the kiln car 2. It moves from the bottom of the kiln car 2 to reset, and will not drive the kiln car 2 to retreat when resetting.

[0050] There are two pushing units 6, one is arranged in the displacement chamber 3, and the other is arranged in the kiln 1 near the displacement chamber 3. One of the two pushing units 6 pushes the kiln car 2 in the displacement chamber 3 into the kiln 1, and the other moves the kiln car 2 in the kiln 1 near the displacement chamber 3 into the kiln 1. This kiln car 2 is against the next kiln car 2 in the kiln 1 and pushes the remaining kiln cars 2 in the kiln 1 to move, so that the multiple kiln cars 2 are closed, preventing the flame in the kiln 1 from directly rushing to the bottom of the kiln car 2, protecting the bottom support structure of the kiln car 2 from damage.

[0051] It can push the kiln car 2 in the replacement chamber 3 and the kiln 1 to move, and ensure that there is a certain gap between the kiln car 2 in the replacement chamber 3 and the kiln car 2 in the kiln 1. The closing component 4 can close the replacement chamber 3 through the gap, so that the protective gas can be replaced in the replacement chamber 3. After the kiln car 2 enters the kiln 1, the protective gas in the kiln 1 will not leak, thereby ensuring that the protective gas in the kiln 1 protects the product and the heat treatment quality of the product.

[0052] The shallow groove 611, the switching groove 613, the deep groove 612 and the inclined groove 614 form a parallelogram arrangement. The switching groove 613 in one pushing unit 6 extends to the rear of the end of the inclined groove 614 in another pushing unit 6, so that after one pushing unit 6 pushes the kiln car 2 in the replacement chamber 3 into the kiln 1, the pushing block 62 in the pushing unit 6 in the kiln 1 can move to the side of the corresponding kiln car 2 close to the replacement chamber 3 during the next action, thereby pushing the kiln car 2 to move.

[0053] Example 2, reference Figure 1-Figure 15 , which is different from the above embodiment, is that the pushing unit 6 also includes a moving block 63, a moving frame 64 and two limit plates. The moving block 63 is provided with a moving hole, and the moving frame 64 is slidably fitted in the moving hole. The two limit plates are fixedly installed at both ends of the moving frame 64, and the limit plates are against the moving block 63. The pushing block 62 is inserted in the moving frame 64 and slidably fits with the moving frame 64.

[0054] The moving block 63 drives the moving frame 64 to move, and the moving frame 64 drives the pushing block 62 to move. When the pushing block 62 moves in the switching groove 613 and the inclined groove 614, the moving frame 64 can move in the moving hole on the moving block 63. When the pushing block 62 moves in the deep groove 612 and the shallow groove 611, the heights are different. The pushing block 62 can move vertically in the moving frame 64 to change the height.

[0055] Example 3, reference Figure 1-Figure 15 , which is different from the above-mentioned embodiment, the pushing unit 6 also includes a moving rod 65 and a moving ball. The moving rod 65 is rotatably connected to the bottom of the pushing block 62. A ball groove is opened at the bottom of the moving rod 65, and the moving ball is arranged in the ball groove. The groove diameter of the ball groove is smaller than the diameter of the moving ball. The moving rod 65 can move in the shallow groove 611, the switching groove 613, the deep groove 612 and the inclined groove 614. The depth of the deep groove 612 is greater than the depth of the shallow groove 611. The bottom of the switching groove 613 is in the same plane as the bottom of the shallow groove 611. One end of the switching groove 613 is connected to the deep groove 612, and the other end of the switching groove 613 is connected to the shallow groove 611. One end of the inclined groove 614 is connected to the deep groove 612, and the other end of the inclined groove 614 is connected to the shallow groove 611. The bottom of the inclined groove 614 is inclined from the bottom of the deep groove 612 to the bottom of the shallow groove 611.

[0056] The pushing block 62 drives the moving rod 65 to move, and the moving rod 65 moves in the shallow groove 611, the switching groove 613, the deep groove 612 and the inclined groove 614. When the moving rod 65 moves vertically, it drives the pushing block 62 to move.

[0058] The fixed plate 41 and the closing plate 42 move downward, and after the closing plate 42 abuts against the bottom of the kiln 1, the fixed plate 41 continues to move, and the fixed plate 41 drives the pushing inclined block 43, and the pushing inclined block 43 pushes the extrusion inclined block 44 to move, and the extrusion inclined block 44 pushes the closing plate 42 to move toward the displacement chamber 3, and the closing plate 42 is pressed against the displacement chamber 3 to close the displacement chamber 3.

[0059] The glass fiber strip is deformed and pressed against the replacement chamber 3 to provide a buffer, thereby preventing the closing plate 42 from hitting the replacement chamber 3 and causing damage. At the same time, the closing plate 42 and the replacement chamber 3 are sealed to improve the sealing performance.

[0062] The fixing plate 41 in the sealing assembly 4 located at one side of the kiln 1 is slidably matched with the top of the kiln 1 , and the corresponding sealing shell 47 is fully enclosed to prevent the kiln 1 from leaking.
