Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, specifically to an electric heating forced-air drying oven for brick and slab production. Background Technology

[0002] Bricks are small, man-made building blocks, typically made from raw materials such as clay, shale, and coal gangue through molding, drying, and firing. Brick slabs are a type of brick, and they require drying in a drying oven during production.

[0003] For example, Chinese patent application CN222069133U discloses an electric heating drying oven, including a box body, an electric blower fixedly installed inside the box body; a tray rotatably installed inside the box body, on which materials are placed; a heating chamber fixedly installed inside the box body, the heating chamber being fixedly connected to the air outlet of the electric blower; multiple air outlets evenly opened on the heating chamber, and multiple ventilation holes evenly opened on the tray; the multiple air outlets on the heating chamber all face the tray and correspond to the ventilation holes on the tray; and a motor is fixedly installed inside the box body.

[0004] Chinese patent application CN222123736U discloses an electric heating drying oven, including a drying oven, a cooling chamber fixedly installed on the left side of the drying oven, a cooling pipe fixedly installed in the inner cavity of the cooling chamber, a water pump fixedly installed at the bottom of the cooling pipe, a cooling box fixedly connected to the bottom end of the cooling pipe, a support frame fixedly installed in the inner cavity of the cooling chamber, a servo motor fixedly installed on the left side of the support frame, and a fan blade fixedly mounted on the output shaft of the servo motor.

[0005] In summary, the aforementioned electric heating drying ovens all involve placing the items to be dried inside the oven for drying, and then removing them after a period of drying. Furthermore, the quantity dried is limited. This batch drying method requires going through the entire process of heating, maintaining a constant temperature, and cooling, which not only leads to low production efficiency but also reduces flexibility.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] In view of the problems in the related technologies, this utility model proposes an electric heating forced-air drying oven for brick and slab production, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] Therefore, the specific technical solution adopted by this utility model is as follows:

[0009] An electric heating drying oven for brick production includes: a drying chamber body with a partition at the bottom and openings on both sides of the bottom; a heating chamber located at the top center of the drying chamber body; a blower located on one side of the heating chamber body, with its output port connected to the interior of the heating chamber; an air outlet mechanism located at the top of the drying chamber body and connected to the bottom of the heating chamber; a brick conveying mechanism symmetrically arranged on both sides of the partition for conveying bricks; a stop plate symmetrically arranged at the top of the partition; a control box located on one side of the drying chamber body; and an electric telescopic rod located at the top of one end of the drying chamber body, with one end of the piston rod penetrating one side wall of the drying chamber body and having a push plate.

[0010] Furthermore, in order to heat the air and provide a sufficient heat source for drying the bricks, ensuring that the bricks can be dried in a suitable temperature environment, the heating chamber is equipped with several heating rods, which are evenly arranged inside the heating chamber.

[0011] Furthermore, in order to allow the hot air entering the air outlet plate to diffuse naturally to both sides, the guide blocks, inclined plates, and guide vanes inside the air outlet plate work together to help distribute the airflow, so that the hot air is evenly output in the width direction at the bottom of the air outlet plate, thereby achieving the heating and drying of the brick plate. The air outlet mechanism includes a vent pipe connected to the bottom of the heating box, and an air outlet plate is set at the bottom of the vent pipe. The cross-section of the air outlet plate is a trapezoidal structure. Guide blocks are symmetrically arranged on the top side wall inside the air outlet plate. Several inclined plates are symmetrically arranged in the middle of the air outlet plate. Several evenly arranged guide vanes are set at the bottom of the air outlet plate. The inclination of the several inclined plates located at one end inside the air outlet plate gradually increases along the direction away from the vent pipe.

[0012] Furthermore, to facilitate the conveying of bricks, a lifting assembly can lift and convey the brick placement boxes. Then, with the assistance of a stacking assembly, the brick placement boxes are stacked together, allowing them to automatically enter the high-temperature drying zone and be conveyed out after drying. This significantly improves production flexibility and efficiency. The brick conveying mechanism includes a support plate at the bottom of the drying chamber, with a lifting assembly running through the center of the bottom end of the support plate. Support frames are symmetrically arranged on both sides of the top of the support plate, and a conveyor belt is installed on one side of each support frame. A stacking assembly is located at the bottom of each support frame, and limit frames are installed on both sides of the support frames. The two sets of support frames are equipped with several brick placement boxes inside; the lifting assembly includes sleeves symmetrically inserted at the bottom of the support plate, with a mounting plate at the bottom of the sleeve, and a first hydraulic telescopic rod at the top center of the mounting plate. The piston rod of the first hydraulic telescopic rod passes through the top of the support plate and is equipped with a top plate; the stacking assembly includes a connecting seat at the bottom of the support frame, with a second hydraulic telescopic rod at the top of the connecting seat, and a connecting rod at the top of the piston rod of the second hydraulic telescopic rod. A rotating shaft passes through one end of the connecting rod, and stacking rods are symmetrically arranged at both ends of the outer circumference of the rotating shaft, with the cross-section of the stacking rods being L-shaped.

[0013] Furthermore, in order to allow hot air to circulate inside the brick placement box and ensure that all parts of the bricks are fully exposed to the hot air for uniform drying, ventilation holes are provided at the bottom and all four side walls of the brick placement box. Several support strips are provided at the bottom of the brick placement box. Several upright plates are provided at both ends of the top of the brick placement box, and sliding grooves that cooperate with the upright plates are provided at both ends of the bottom of the brick placement box.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model has a reasonable and reliable structure. With the cooperation of the heating box and the blower, it can blow air into the air outlet mechanism and deliver hot air evenly into the drying box, providing a stable and sufficient heat source for brick drying. This ensures that the bricks can be heated and dried quickly and evenly. Furthermore, the bricks are transported in an inverted U-shape, which allows for the initial heating, drying and gradual cooling of the bricks, ensuring the quality of the dried bricks.

[0016] 2. By setting up an air outlet mechanism, the hot air entering the air outlet plate is naturally diffused to both sides. The guide blocks, inclined plates and guide vanes in the air outlet plate work together to help distribute the airflow, so that the hot air is evenly output in the width direction at the bottom of the air outlet plate, thereby achieving the heating and drying of the brick plate.

[0017] 3. By setting up a brick conveying mechanism, the bricks are conveyed. The lifting component can lift and convey the brick placement box, and then the stacking component can stack the brick placement boxes. This allows the brick placement boxes to automatically enter the high-temperature drying zone and be conveyed out after drying, greatly improving the flexibility and efficiency of production.

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. 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.

[0029] According to an embodiment of the present invention, an electric heating forced-air drying oven for brick and slab production is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-7 As shown, the electric heating drying oven for brick production according to an embodiment of the present invention includes: a drying chamber 1, with a partition 2 at the bottom of the drying chamber 1, and openings 3 on both sides of the bottom of the drying chamber 1; a heating chamber 4, located at the top center of the drying chamber 1; a blower 5, located on one side of the heating chamber 4, with the output port of the blower 5 connected to the interior of the heating chamber 4; an air outlet mechanism 6, located at the top of the drying chamber 1, and connected to the bottom of the heating chamber 4; a brick conveying mechanism 7, symmetrically arranged on both sides of the partition 2, for conveying bricks; a stop plate 8, symmetrically arranged at the top of the partition 2; a control box 9, located on one side of the drying chamber 1; an electric telescopic rod 10, located at the top of one end of the drying chamber 1, with one end of the piston rod of the electric telescopic rod 10 penetrating one side wall of the drying chamber 1 and having a push plate 11; and a plurality of heating rods 401 arranged evenly inside the heating chamber 4.

[0031] It should be noted that the control box 9 contains a PLC controller, and the heating box 4, blower 5, brick conveying mechanism 7, and electric telescopic rod 10 are all connected to the PLC controller. By receiving preset program instructions and feedback signals from each component, the PLC controller can precisely control the operating status, action time, and sequence of each component to achieve automation, intelligence, and efficiency in brick drying production. For example, the PLC controller sends a control signal to the first hydraulic telescopic rod 7023 of the lifting assembly 702 in the brick conveying mechanism 7. The PLC controller precisely controls the extension speed and stroke of the piston rod of the first hydraulic telescopic rod 7023, so that it slowly and steadily lifts the top plate 7024 upward according to a predetermined program, thereby driving the brick placement box 707 to gradually rise to the height of the conveyor belt 704.

[0032] In addition, heating rod 401 is an electric heating rod. When heating rod 401 is powered on, the resistance wire inside it will generate heat due to the current passing through it.

[0033] With the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable. With the cooperation of the heating box 4 and the blower 5, air is blown into the air outlet mechanism 6 and hot air is evenly delivered into the drying box 1, providing a stable and sufficient heat source for the drying of bricks and ensuring that the bricks and slabs can be heated and dried quickly and evenly. Moreover, the bricks and slabs are transported in an inverted U-shape, which enables the bricks and slabs to undergo the initial heating, drying and gradual cooling process, ensuring the quality of the dried bricks and slabs.

[0034] In one embodiment, the air outlet mechanism 6 includes a vent pipe 601 connected to the bottom of the heating box 4, and an air outlet plate 602 is provided at the bottom of the vent pipe 601. The air outlet plate 602 has a trapezoidal cross-section. Guide blocks 603 are symmetrically arranged on the top sidewall of the air outlet plate 602, and several inclined plates 604 are symmetrically arranged in the middle of the air outlet plate 602. Several uniformly arranged guide vanes 605 are provided at the bottom of the air outlet plate 602. The inclination of the inclined plates 604 located at one end of the air outlet plate 602 gradually increases along the direction away from the vent pipe 601, so that the hot air entering the air outlet plate 602 naturally diffuses to both sides. The guide blocks 603, inclined plates 604 and guide vanes 605 in the air outlet plate 602 cooperate with each other to help distribute the airflow, so that the hot air is evenly output in the width direction of the bottom of the air outlet plate 602, thereby realizing the heating and drying of the brick.

[0035] The working principle of the air outlet mechanism 6 is as follows: the hot air generated by the heating box 4 enters the air outlet plate 602 through the vent pipe 601 connected to the bottom of the heating box 4. After entering the air outlet plate 602, the hot air first comes into contact with the guide blocks 603 symmetrically arranged on the top side wall of the air outlet plate 602. The guide blocks 603 can initially guide and divert the hot air entering the air outlet plate 602, so that the hot air can be distributed more evenly in the upper space of the air outlet plate 602, avoiding the hot air from concentrating at the inlet. Several inclined plates 604 are symmetrically arranged in the middle of the air outlet plate 602, which can diffuse the hot air to both sides. Then, the guide vanes 605 make the final adjustment and guidance of the hot air, so that the hot air is output at a uniform speed and flow rate in the width direction of the bottom of the air outlet plate 602.

[0036] In one embodiment, the brick conveying mechanism 7 includes a support plate 701 disposed at the bottom of the drying chamber 1, a lifting assembly 702 passing through the middle of the bottom end of the support plate 701, support frames 703 symmetrically disposed on both sides of the top end of the support plate 701, and a conveyor belt 704 disposed on one side of the support frame 703; a stacking assembly 705 is disposed at the bottom inside the support frame 703, and limit frames 706 are disposed on both sides of the support frame 703 (in addition, in specific applications, the height of the limit frame 706 near the partition 2 is...). (The height is lower than the limit frame 706 away from the partition 2), and several brick placement boxes 707 are provided inside the two sets of support frames 703; the lifting assembly 702 includes sleeves 7021 symmetrically inserted at the bottom end of the support plate 701, the bottom end of the sleeve 7021 is provided with a mounting plate 7022, and the top center of the mounting plate 7022 is provided with a first hydraulic telescopic rod 7023, the piston rod of the first hydraulic telescopic rod 7023 passes through the top end of the support plate 701 and is provided with a top plate 7024; the stacking assembly 705 includes a brick placement box 707 provided inside the bottom end of the support frame 703. A connecting seat 7051 has a second hydraulic telescopic rod 7052 at its top. A connecting rod 7053 is located at the top of the piston rod of the second hydraulic telescopic rod 7052. A rotating shaft 7054 is threaded through one end of the connecting rod 7053. Stacking rods 7055 are symmetrically arranged at both ends of the outer circumference of the rotating shaft 7054, and the stacking rods 7055 have an L-shaped cross-section. Ventilation holes 7071 are provided at the bottom and all four side walls of the brick placement box 707. Several support bars 70 are provided at the bottom of the brick placement box 707. 72; Several upright plates 7073 are provided at both ends of the top of the brick placement box 707, and sliding grooves 7074 that cooperate with the upright plates 7073 are provided at both ends of the bottom of the brick placement box 707, thereby realizing the conveying of bricks. The brick placement box 707 can be lifted and conveyed by the lifting component 702, and then the stacking component 705 realizes the stacking process between the brick placement boxes 707, realizing the automatic entry of the brick placement box 707 into the high-temperature drying zone, and conveying it out after drying, which greatly improves the flexibility and efficiency of production.

[0037] In addition, it should be noted that the conveyor belt 704 is composed of a transmission belt, a drive roller, a driven roller, a transmission device, a drive motor, and other components, which can transport and move the brick placement box 707. The working principle and structural composition of the conveyor belt 704 are existing technologies, so they will not be elaborated on here.

[0038] In addition, before conveying the brick placement box 707, multiple brick placement boxes 707 can be pre-arranged on the brick conveying mechanism 7 manually to ensure the continuous conveying of the brick placement box 707.

[0039] The working principle of the brick conveying mechanism 7 is as follows: First, the bricks to be dried are placed in the brick placement box 707. The support strip 7072 at the bottom of the brick placement box 707 provides support for the bricks, creating a certain gap between the bricks and the bottom of the brick placement box 707, allowing hot air to pass through from the bottom and dry the bottom of the bricks. At the same time, the ventilation holes 7071 at the bottom and on the side walls of the brick placement box 707 ensure that the hot air can pass through evenly and heat and dry the bricks from all directions. Then, the brick placement box 707 is placed on the conveyor belt 704 and conveyed to the top plate. Then, the brick placement box 707 is blocked by the limiting frame 706 near the partition 2. Then, the mechanism is started. The first hydraulic telescopic rod 7023 lifts the brick placement box 707. At this time, the stacking rod 7055 is tilted upward. When the brick placement box 707 is lifted to a position higher than the preset position of the rotating shaft 7054, the piston rod of the second hydraulic telescopic rod 7052 moves upward, which drives the rotating shaft 7054 to rotate and drives the stacking rod 7055 to rotate, so that the top of the stacking rod 7055 remains horizontal. Then the first hydraulic telescopic rod 7023 is activated to lower the brick placement box 707, so that the brick placement box 707 lands on the top of the stacking rod 7055. Then the piston rod of the first hydraulic telescopic rod 7023 continues to descend to the initial position to prepare for lifting the next brick placement box 707.

[0040] As the brick placement box 707 gradually rises, they stack one on top of the other. When the topmost brick placement box 707 reaches the push plate 11, the electric telescopic rod 10 moves the push plate 11, pushing the brick placement box 707 towards the stopping plate 8, where it stops. At this point, another brick placement box 707 is stacked on the brick conveying mechanism 7 near the electric telescopic rod 10. After drying for a period of time, the electric telescopic rod 10 then moves the push plate 11 again. 1. Move the brick board placement box 707 at the top of the brick board conveying mechanism 7 near the electric telescopic rod 10. Then, push the brick board placement box 707 on the stop plate 8 to move to the brick board conveying mechanism 7 on the other side. Then, the brick board conveying mechanism 7 on the side away from the electric telescopic rod 10 and the brick board conveying mechanism 7 on the side near the electric telescopic rod 10 operate in opposite directions, so that the brick board placement box 707 gradually moves downward and is conveyed to the next process for subsequent processing by the conveyor belt 704, thereby improving the efficiency of the brick drying process.

[0041] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0042] In practical applications, the bricks to be dried are first conveyed to the interior of the drying chamber 1 by the brick conveying mechanism 7. Then, they are conveyed in an inverted U-shape inside the drying chamber 1. During the conveying process, the blower 5 is started and draws in outside air from its inlet. The air is then blown into the heating chamber 4 at a certain wind speed. The heating rod 401 inside the heating chamber 4 heats the incoming air, raising the air temperature to a set value, forming hot air, which is then conveyed to the air outlet mechanism 6 to achieve uniform dispersion of the hot air and dry the bricks.

[0043] In summary, with the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable. It can, in conjunction with the heating box 4 and the blower 5, blow air into the air outlet mechanism 6 and evenly deliver hot air into the drying chamber 1, providing a stable and sufficient heat source for brick drying. This ensures that the bricks can be heated and dried quickly and evenly. Furthermore, the bricks are transported in an inverted U-shape, allowing for initial heating, drying, and gradual cooling, thus guaranteeing the quality of the dried bricks. By setting the air outlet mechanism 6, the hot air entering the air outlet plate 602 naturally diffuses to both sides, and the air outlet plate 602... The structure, including the guide block 603, inclined plate 604, and guide vane 605, works together to help distribute the airflow, ensuring that hot air is evenly output in the width direction at the bottom of the air outlet plate 602, thus heating and drying the bricks. The brick conveying mechanism 7 is used to convey the bricks. The lifting component 702 can lift and convey the brick placement box 707, and then the stacking component 705 can stack the brick placement boxes 707 together, enabling the brick placement boxes 707 to automatically enter the high-temperature drying zone and be conveyed out after drying, which greatly improves the flexibility and efficiency of production.
