[0001] The utility model relates to the technical field of mesh belt furnaces, in particular to an air intake and exhaust device for a mesh belt furnace. Background Art

[0002] The air intake and exhaust of traditional mesh belt furnaces are designed directly on the muffle furnace. After a period of use, the precipitates from the product sintering process will adhere to the inlet and exhaust ports and the inner wall of the furnace, causing the diameter of the inlet and exhaust pipes to become smaller, affecting the consistency of the products sintered in the furnace. Utility Model Content

DETAILED DESCRIPTION

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] Example

[0024] This embodiment provides a mesh belt furnace air intake and exhaust device, such as Figure 1As shown, the air intake and exhaust device includes a movable part that can enter and exit the interior of the furnace body, and the movable part is evenly distributed with air intake ports 9 and exhaust ports 8 that are connected to the interior of the furnace body. The movable part is provided with an air intake mechanism connected to the air intake port 9 and an exhaust mechanism connected to the exhaust port 8. In this embodiment, the air intake port 9 and the exhaust port 8 are installed on the movable part, and the movable part can slide in and out of the furnace body like a drawer structure, thereby completing the structure of separating the air intake and exhaust device from the furnace body. When the air intake and exhaust device is dirty, it is convenient to pull out and take care of it. Since the previous air intake and exhaust pipes 4 are all fixedly installed on the furnace body, the use of this air intake and exhaust device can facilitate replacement of the entire device, ensuring work efficiency. In addition, independent air intake mechanisms and exhaust mechanisms are respectively used on the movable part to complete the air intake and exhaust work. The air intake and exhaust device can be separated from the furnace body through the movable part, ensuring the reliability of the air intake and exhaust work, and thus ensuring the consistency of the product.

[0025] Specifically, the moving part of this embodiment is selected as the moving bed 1, such as Figure 2 As shown, a bed pillow 2 is provided at one end of the movable bed 1. An air inlet 9 and an exhaust port 8 are provided on the movable bed 1. The air inlet mechanism includes an air inlet pipe 3, and the exhaust mechanism includes an exhaust pipe 4. The air inlet 9 and the exhaust port 8 are arranged alternately. One end of the air inlet pipe 3 is connected to the air inlet 9, and one end of the exhaust pipe 4 is connected to the exhaust port 8. The other ends of the air inlet pipe 3 and the exhaust pipe 4 both extend from the bed pillow 2. In this embodiment, the movable bed 1 is selected as the carrier of the air inlet and exhaust device. The position of the air inlet and exhaust device is changed by sliding the movable bed 1, thereby transporting the air inlet and exhaust device designed in this scheme into or out of the furnace body. The bed pillow 2 is used for limiting or moving the position, and the four air inlet and exhaust pipes are integrated therein. Since the bed pillow 2 is arranged outside the furnace body, the air inlet pipe 3 and the exhaust pipe 4 extend from the bed pillow 2, ensuring the rational arrangement of the four air inlet and exhaust pipes.

[0026] During operation, the moving bed 1 has a length and a width, and an air intake mesh cover and an exhaust box are provided on the bottom end face of the moving bed 1. Side mesh covers 5 are provided on both sides of the bottom of the moving bed 1, and the front and rear ends of the moving bed 1 are respectively provided with a front mesh cover 6 and a rear end mesh cover 7. The side mesh cover 5 includes a first side mesh cover 5a and a second side mesh cover 5b. The air intake mesh cover, the exhaust box, the front mesh cover 6 and the rear end mesh cover 7 are all arranged along the width direction of the moving bed 1, and the first side mesh cover 5a and the second side mesh cover 5b are both set along the length direction of the moving bed 1, wherein the air intake mesh cover, the first side mesh cover 5a, the second side mesh cover 5b, the front mesh cover 6 and the rear end mesh cover 7 are all provided with an air intake port 9, and the exhaust box is provided with an exhaust port 8.

[0027] In this embodiment, the first side mesh cover 5a and the second side mesh cover 5b are both pipes with elliptical cross sections, and the air inlets 9 are densely distributed on the pipes.

[0028] It can be further seen that in this embodiment, a variety of mesh covers are installed at the bottom of the movable bed 1 for uniform air intake and exhaust. In addition to the air inlet 9 at the bottom end face of the movable bed 1, air inlets 9 are set on both sides and front and back of the movable bed 1, which increases the air intake area and can replenish air to the contact surface between the product and the furnace body, thereby improving the consistency of the product.

[0029] In order to meet the production needs, Figure 2 and 3 As shown, the movable bed 1 can also be provided with a sampling mechanism and a sampling port 15. The sampling port 15 is provided on the bottom end surface of the movable bed 1. The sampling mechanism includes a sampling tube 12. One end of the sampling tube 12 is connected to the sampling port 15, and the other end extends from the bed pillow 2.

[0030] Since a sampling mechanism is designed on the movable bed 1, sampling is achieved by adding a sampling port 15 on the movable bed 1 and connecting the sampling tube 12 to the sampling port 15. The sampling tube 12 is also integrated into the bed pillow 2. The structural arrangement is reasonable, which also improves the use effect of the device.

[0031] Specifically, an exhaust port 11 is provided on the upper end surface of the pillow 2, to which one end of the exhaust pipe 4 is connected. An air inlet port 13 and a sampling port 14 are provided on one side of the pillow 2. One end of the air inlet pipe 3 is connected to the air inlet port 13, and one end of the sampling tube 12 is connected to the sampling port 14. The sampling device used has a simple structure and is easy to maintain.

[0032] For example Figure 1 As shown, the exhaust pipe 4 in the pillow 2 adopts a three-way structure, one end of which is connected to the exhaust interface 11, and the other end is provided with an exhaust inspection port 10, which can minimize the exhaust blockage.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
