Energy-saving drying equipment for refractory bricks

Abstract

This utility model discloses an energy-saving drying device for refractory bricks, including a dryer and a base. By employing a support plate and a connecting plate, the refractory bricks are stacked one by one on a rack on top of the support plate during the drying process. Since the rack is open in the middle, the bottom surface of the refractory bricks is exposed, allowing heat to be directly applied to it. After placement, the rotation of the connecting plate causes it and the drying pipe to move in a circular motion along the support plate. Simultaneously, the drying pipe sprays hot air onto the upper and lower surfaces of the support plate, ensuring uniform heating of different positions and surfaces of the refractory bricks. This improves overall heating uniformity and drying effect, facilitating faster and better drying operations. It offers advantages such as good drying effect and uniform heating.

Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and more specifically, to an energy-saving drying equipment for refractory bricks. Background Technology

[0002] The production process of refractory bricks mainly includes four steps: raw material proportioning, grinding, pressing and sintering. Refractory bricks after pressing usually contain a certain amount of moisture. If they are sintered directly, the moisture inside the brick will quickly vaporize, which may cause the brick to crack or deform. Therefore, the pressed bricks need to be placed in a drying equipment to dry them first, so that the moisture inside the brick can gradually evaporate, in order to avoid cracks or explosions during the subsequent sintering process.

[0003] The existing publicly available technology, application number CN202322157798.8, describes a refractory brick drying device. Through the multi-layer design of the pusher plate, small heating compartments are formed between the partitions, which increases the contact between hot air and refractory bricks, making it easier to dry the refractory bricks. At the same time, the multi-layer design can also hold more refractory bricks, improving work efficiency.

[0004] However, the aforementioned patent still has certain drawbacks in its use: although it can dry refractory bricks, the bottom surface of the refractory bricks is obstructed when placed on the clamps, and the fixed position of the air outlet pipe results in a fixed position of the subsequently discharged hot air. Consequently, the heating effect between the top and bottom surfaces, as well as between the refractory bricks near and away from the hot air, is not uniform during subsequent drying. This leads to problems such as the top surface being dried completely while the bottom surface still has a high moisture content, and the outer refractory bricks not drying in time. This results in a delayed drying time, poor overall drying uniformity and quality, and increased energy consumption. Furthermore, the water vapor generated during drying also contains some heat, and direct discharge of this heat energy leads to a waste of thermal energy, which is not conducive to more energy-efficient and environmentally friendly use. Therefore, the effect of the device is not ideal.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0011] Furthermore, a circulation chamber is provided inside the surface of the dryer near the connecting arm.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides an energy-saving drying equipment for refractory bricks, which has the following beneficial effects:

[0020] (1) This utility model adopts a support plate and a connecting plate. When drying refractory bricks, the refractory bricks can be stacked one by one on the placement rack on the top of the support plate. Since the middle of the placement rack is open, the bottom surface of the refractory bricks can be exposed. In this way, the heat can be directly applied to the bottom surface of the refractory bricks, expanding the drying area and improving the drying effect. After the placement is completed, the rotation of the connecting plate can drive the connecting plate on its surface and the drying pipe on the connecting plate to move in a circle along the support plate. The drying pipe can spray hot air onto the upper and lower surfaces of the support plate at the same time, so that the refractory bricks in different positions and different surfaces of the refractory bricks can be heated evenly and synchronously during the operation, thereby improving the overall heating uniformity and drying effect. It is convenient to carry out the drying operation faster and better, and has the advantages of good drying effect and uniform heating.

[0021] (2) This utility model adopts a circulation chamber. When drying refractory bricks, the heat-containing moisture generated during drying will enter the circulation chamber through the air outlet. Since the circulation chamber is located inside the dryer, heat can be transferred to the circulation chamber when the moisture is discharged through the circulation chamber, thereby realizing the heat preservation and heating operation inside the dryer, reducing the consumption required to maintain the internal temperature, thus achieving a certain degree of heat energy reuse and energy saving effect, making it easier to use and having the advantage of heat energy reuse.

With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, an energy-saving drying device for refractory bricks is provided.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, an energy-saving drying device for refractory bricks according to an embodiment of the present invention includes a dryer 1 and a base 21. A fixing rod 17 is welded to the middle of the bottom of the dryer 1. Several sets of bearing plates 18 are uniformly fixedly installed on the surface of the fixing rod 17. Several sets of placement racks 19 are installed around the surface of the bearing plates 18. An open groove 22 is opened in the middle of the surface of the placement racks 19. Drying pipes 15 are symmetrically arranged at both ends of the bearing plates 18. A connecting arm 14 is connected to one end of the drying pipe 15. A connecting plate 13 is connected to the top of the connecting arm 14. A drive shaft 8 is fixedly installed at the middle of the top of the connecting plate 13 and is rotatably connected to the surface of the dryer 1. A motor 11 is fixedly installed on one side of the top of the drive shaft 8 at the surface of the dryer 1. Transmission gears 10 are installed at the output end of the motor 11 and at the surface of the drive shaft 8. A transmission chain 9 is connected between the transmission gears 10. A heat conduction pipe 7 is rotatably connected to the top of the drive shaft 8. A hot air blower 6 is connected to one end of the heat conduction pipe 7. Several sets of hot air nozzles 16 are uniformly installed on the surface of the drying pipes 15.

[0032] In one embodiment, a circulation chamber 3 is provided inside the surface of the dryer 1 near the connecting arm 14. An air outlet pipe 12 is connected to the top of one side of the circulation chamber 3, and the other end of the air outlet pipe 12 is connected to the middle of the interior of the dryer 1. The top of the other side of the circulation chamber 3 is connected to the exhaust pipe 4 through one side of the dryer 1. The purpose of the air outlet pipe 12 is to introduce the heat-containing moisture generated during the drying of refractory bricks into the circulation chamber 3, so that the circulation chamber 3 can reuse the heat contained in the moisture, thereby maintaining the temperature of the drying area, reducing the rate of heat loss, and improving the drying effect.

[0033] In one embodiment, the inner and outer surfaces of the dryer 1 are filled with a heat insulation layer 2. The purpose of the heat insulation layer 2 is to insulate the interior of the dryer 1, reduce the rate of heat loss, and thus reduce the consumption of maintaining the temperature, thereby achieving the effect of energy saving. At the same time, the heat insulation layer 2 can be adjusted according to the needs of personnel, such as using heat insulation cotton, heat insulation board, etc. Since the setting of the heat insulation layer 2 is a common measure, it will not be described in detail.

[0034] In one embodiment, a pressure relief valve 5 is installed on one side of the top of the dryer 1. The pressure relief valve 5 is set to prevent excessive internal pressure in the dryer 1 and ensure the safe use of the device. Since the pressure relief valve 5 is a common structure, it will not be described in detail.

[0035] In one embodiment, a base 21 is fixedly installed at the bottom of the dryer 1. The base 21 can fix the entire device, thereby enhancing the overall stability of use.

[0036] In one embodiment, cavities for hot air flow are provided inside the drive shaft 8, the connecting plate 13, and the exhaust pipe 4. The cavities are designed to facilitate the flow of hot air, so that the hot air can be smoothly discharged from the hot air nozzle 16, which facilitates the subsequent drying operation of the refractory bricks.

[0037] In one embodiment, a drain pipe 20 is installed through one side of the bottom of the circulation chamber 3. The drain pipe 20 is provided to discharge the water generated after the condensation of the hot and humid air flowing inside the circulation chamber 3, so as to avoid clogging inside the circulation chamber 3 and affecting the circulation of hot air.

[0038] In one embodiment, the size of the open groove 22 is smaller than the size of the refractory brick. The size of the open groove 22 is set to ensure that the bottom surface of the refractory brick can be exposed smoothly, while preventing the refractory brick from falling off. This ensures that the bottom surface of the refractory brick can fully contact the hot air during subsequent drying, thereby expanding the drying area and improving the drying effect.

[0039] Working Principle: In actual use, personnel can place the refractory bricks to be dried one by one onto the placement rack 19 on top of the support plate 18. Since the placement rack 19 has a through structure, the bottom surface of the refractory bricks will be exposed after placement. Then, during subsequent drying, the operation of the motor 11 drives the drive shaft 8 to rotate through the transmission gear and transmission chain 9. The rotation of the drive shaft 8 drives the connecting plate 13 connected to its bottom to rotate, and the connecting plate 13 drives the connecting arm 14 connected to its bottom to rotate. At this time, the connecting arm 14 can rotate around the support plate 18. Moreover, the surface of the connecting arm 14 is equipped with drying pipes 15 on both the upper and lower sides of the support plate 18. Therefore, the hot air sprayed through the drying pipes 15 can act on the refractory bricks respectively. The upper and lower surfaces of the bricks are dried to expand the overall drying range, thereby improving drying efficiency. The drying structure rotates along the bearing plate 18, which can evenly apply the drying to the refractory bricks at different locations, thereby improving the uniformity of the drying operation and enhancing the overall drying quality. The heat-containing moisture generated during drying enters the circulation chamber 3 through the exhaust pipe 12. Since the circulation chamber 3 is located inside the dryer 1, heat can be transferred to the circulation chamber 3 when the moisture is discharged through it, thereby achieving heat preservation and heating of the inside of the dryer 1, reducing the consumption required to maintain the internal temperature, and thus achieving a certain degree of heat energy reuse and energy saving. This facilitates better use. The device as a whole has the advantages of good drying effect, heat energy reuse, and uniform heating.
