Description

Technical Field

[0001] This application relates to the field of building material processing equipment technology, and in particular to an energy-saving building material drying equipment and its usage method. Background Technology

[0002] During the production and processing of building boards, drying is often required to remove internal moisture and improve their stability and performance. Currently, the most common building board drying equipment usually uses electric heating plates to dry the boards. Its structure generally includes a drying chamber, heating elements and board support frame. During drying, the boards are sent into the drying chamber and the moisture is evaporated by heating with electric heating plates. However, the aforementioned existing equipment has the problem of high energy consumption in actual use; First, the existing drying ovens generally lack sufficient sealing. In order to ensure that water vapor can be discharged in time, the oven usually needs to have a constantly open exhaust port or ventilation structure, which causes a large amount of hot air to escape with the water vapor during the heating process, resulting in low heat energy utilization. The heating plate needs to operate at high power continuously to make up for the heat loss. Secondly, after the drying process is completed and the heating device is turned off, the high-temperature water vapor remaining inside the chamber will quickly condense into liquid water when it encounters the cold. However, the existing equipment lacks an effective condensate collection and treatment structure. This condensate is easily reabsorbed by the dried board, causing the moisture content of the board to rise again, requiring secondary drying and resulting in repeated energy consumption. In addition, some drying equipment is equipped with fans to blow out water vapor and prevent it from being reabsorbed by the dried boards. However, the introduction of fans not only increases the power consumption of the equipment itself, but also the forced ventilation will further accelerate the loss of hot air inside the chamber, resulting in more serious heat loss and exacerbating the energy consumption problem. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide an energy-saving building material drying equipment and its usage method to solve the problem of excessive energy consumption of existing building material drying equipment.

[0004] To solve the above-mentioned technical problems, this application provides the following technical solution: An energy-saving building material drying device includes: a drying chamber, a chute, a mounting plate, a hydraulic rod, a sealing door, a connecting block, and a material support plate. The drying chamber has chutes on both sides inside. A mounting plate is fixedly installed on the left end of the bottom surface of the drying chamber. A hydraulic rod is mounted on the mounting plate, and a connecting block is fixedly installed at the output end of the hydraulic rod. A sealing door is fixedly installed on the top of the connecting block. A material support plate is fixedly installed below the right side surface of the sealing door and slides within the two chutes. Heating plates are installed on the top and sides of the inner side of the drying chamber. A mounting groove is fixedly installed on the bottom inner side of the drying chamber, and an absorbent sponge is fixedly installed within the mounting groove. A scraper is fixedly installed at the right end of the absorbent sponge. An extrusion strip is fixedly installed on the right side of the bottom surface of the material support plate.

[0005] Preferably, the plate support plate is a grating plate, and the thickness of the plate support plate is the same as the height of the chute.

[0006] Preferably, the bottom horizontal height of the plate support is equal to the inner bottom horizontal height of the drying oven, the upper surface horizontal height of the absorbent sponge is equal to the bottom surface horizontal height of the drying oven, and the upper surface horizontal height of the scraper is equal to the inner bottom horizontal height of the drying oven.

[0007] Preferably, the width of the extrusion strip is equal to the width of the mounting groove, and the extrusion strip extends into the mounting groove. The extrusion strip is located on the right side of the scraper. When the hydraulic rod is extended to its maximum length, the water-absorbing sponge is in a state of maximum compression.

[0008] Preferably, a drainage groove is provided at the lower left end of the drying oven, and a sealing plug is fixedly provided at the bottom right side surface of the sealing door. The sealing plug matches the drainage groove. When the sealing door is attached to the left end of the drying oven, the sealing door and the left end opening of the drying oven are airtightly connected. At this time, the sealing plug on the sealing door is embedded in the drainage groove to seal the drainage groove.

[0009] Preferably, the bottom surface of the scraper is attached to the bottom surface of the mounting groove, and the scraper and the mounting groove are connected in an airtight manner.

[0010] Preferably, support bars are fixedly installed on both the inner and outer sides of the bottom surface of the drying oven, and wheels are fixedly installed on both the inner and outer sides of the bottom surface of the sealing door. The bottom horizontal height of the support bars is equal to the bottom horizontal height of the wheels, and the bottom horizontal height of the support bars is lower than the bottom horizontal height of the hydraulic rod.

[0011] Preferably, multiple board support plates are fixedly arranged on the upper surface of the board support plate from left to right, and the distance between two adjacent board support plates is adapted to the thickness of the board to be dried.

[0012] Preferably, a vacuum pump is installed through the center of the upper surface of the drying oven, and a pressure detection sensor is installed inside the drying oven.

[0013] A method for using an energy-saving building material drying equipment includes the following steps: S1: Activate the hydraulic rod to extend it, causing the sealing door and the plate support plate to extend out of the drying chamber. Then, place the plate to be dried vertically on the plate support plate and insert it between two adjacent plate support plates. Then, the hydraulic rod is activated to retract, causing the sealing door to move towards the drying chamber. At the same time, the plate support plate slides along the slide groove until the plate is completely inside the drying chamber. At this point, the sealing door closes the left opening of the drying chamber, and the sealing plug blocks the drainage groove. S2: The inside of the drying oven is evacuated to a sub-vacuum state by a vacuum pump, and then the electric heating plate is activated to heat and dry the board. S3: After drying is complete, turn off the heating plate and vacuum pump. The steam in the drying chamber will condense and be quickly absorbed by the water-absorbing sponge. Start the hydraulic rod again to extend it, which will move the sealing door and the plate support plate to the left. The sealing plug will disengage from the drainage groove. At the same time, the extrusion strip will move to the left with the plate support plate and squeeze the water-absorbing sponge, so that the water absorbed in the sponge will be squeezed out. The squeezed-out water is discharged through the drainage channel under the obstruction and guidance of the scraper. After the board support plate is completely removed from the drying oven, the dried board is taken off.

[0014] Compared with the prior art, this application has at least the following advantages: In this invention, by incorporating an absorbent sponge and installing it in a mounting groove at the bottom inner side of the drying chamber, the residual high-temperature water vapor in the drying chamber condenses upon cooling after the heating plate is turned off. This effectively prevents the condensate from being reabsorbed by the dried board, thus avoiding a rebound in the board's moisture content. This eliminates the need for secondary drying, reducing repeated energy consumption and ensuring the drying quality of the board.

[0015] In this invention, by setting a sealing door and a sealing plug, when the sealing door is attached to the left end of the drying oven, the sealing door and the left end opening of the drying oven are connected in an airtight manner. At the same time, the sealing plug is embedded in the drainage groove to seal the drainage groove, so that the drying oven forms a completely sealed space during the heating and drying process of the electric heating plate. Heat and water vapor cannot overflow and dissipate to the outside. The heat is fully utilized inside the oven, avoiding the problem of large amounts of hot air escaping due to the opening of exhaust vents or poor sealing in traditional equipment. This significantly improves the thermal energy utilization rate and further enhances the energy-saving effect of the equipment.

[0016] In this invention, by incorporating a scraper and an extrusion strip, when the hydraulic rod drives the sealing door and the plate support plate to move to the left for material discharge, the extrusion strip moves synchronously to the left along with the plate support plate and extrudes the absorbent sponge, squeezing out the condensate adsorbed in the sponge. The scraper blocks the right end of the absorbent sponge, allowing the squeezed-out condensate to be discharged through the drainage trough. The extrusion and dehydration of the absorbent sponge and the material discharge are synchronously completed by the same hydraulic rod, eliminating the need for separate extrusion and drainage mechanisms and improving the continuous operation efficiency of the equipment.

[0017] In this invention, multiple support plates are fixedly installed on the upper surface of the board support plate, allowing the boards to be dried to be placed vertically between adjacent support plates. The support plates independently separate and support each board, preventing multiple boards from stacking or sticking together during the drying process. This avoids problems such as obstructed steam discharge and uneven heating caused by the accumulation of boards, ensuring that the surface of each board is fully exposed to the thermal environment inside the drying chamber. This results in uniform heating of all parts of the board and smooth evaporation of moisture, thereby improving drying efficiency and drying quality.

[0018] In this invention, by incorporating a vacuum pump and a pressure sensor, before activating the heating plate to heat the material, the vacuum pump first evacuates the drying chamber to a sub-vacuum state based on the feedback signal from the pressure sensor. This reduces the pressure inside the drying chamber and consequently lowers the boiling point of water. Then, the heating plate is activated for heating and drying, allowing the moisture in the material to evaporate rapidly at a lower temperature. This achieves low-temperature rapid drying, avoiding the problems of cracking, deformation, or surface damage to some heat-sensitive materials caused by high-temperature drying, thus ensuring the drying quality of the material. Furthermore, because the evaporation temperature is lowered, the heating plate does not need to be heated to a high temperature to achieve effective drying, further reducing energy consumption and improving the energy-saving effect of the equipment.

Detailed Implementation

[0022] The following describes in detail an energy-saving building material drying device and its usage method provided in this application, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this application.

[0023] like Figures 1-6 As shown, an embodiment of this application provides an energy-saving building material drying device, including: a drying chamber 1, a chute 101, a mounting plate 3, a hydraulic rod 4, a sealing door 5, a connecting block 7, and a material support plate 8. The drying chamber 1 has chute 101 on both sides inside. The mounting plate 3 is fixedly installed on the left side of the bottom surface of the drying chamber 1. The hydraulic rod 4 is installed on the mounting plate 3. The output end of the hydraulic rod 4 is fixedly provided with a connecting block 7. The top of the connecting block 7 is fixedly installed with a sealing door 5. The lower right side surface of the sealing door 5 is fixedly provided with a material support plate 8, and the material support plate 8 slides in the two chute 101. The top and sides of the inner side of the drying chamber 1 are both equipped with heating plates 11. The bottom of the inner side of the drying chamber 1 is fixedly provided with a mounting groove 102. The mounting groove 10 is fixedly installed in the mounting groove 102. The right end of the water-absorbing sponge 10 is fixedly provided with a scraper 1001. The right side of the bottom surface of the material support plate 8 is fixedly installed with an extrusion strip 9.

[0024] In this embodiment, the plate support plate 8 is a grid plate, and the thickness of the plate support plate 8 is the same as the height of the chute 101, so that the steam generated by the drying of the plate on the plate support plate 8 can pass through the grid plate and be absorbed by the water-absorbing sponge 10.

[0025] By incorporating a water-absorbing sponge 10 and installing a mounting groove 102 at the bottom inner side of the drying chamber 1, the water-absorbing sponge 10 is fixedly installed in the mounting groove 102. After the drying process is completed and the heating plate 11 is turned off, the condensate formed by the condensation of the residual high-temperature water vapor in the drying chamber 1 can be absorbed by the water-absorbing sponge 10 in a timely manner. This effectively avoids the problem of the condensate being reabsorbed by the dried board, which would cause the moisture content of the board to rise again. There is no need to perform secondary drying on the board, thereby reducing repeated energy consumption and ensuring the drying quality of the board.

[0026] In this embodiment, the bottom horizontal height of the board support plate 8 is equal to the inner bottom horizontal height of the drying oven 1, and the upper surface horizontal height of the absorbent sponge 10 is equal to the bottom surface horizontal height of the drying oven 1. The upper surface horizontal height of the scraper 1001 is equal to the inner bottom horizontal height of the drying oven 1. This ensures that the board support plate 8 blocks the top of the absorbent sponge 10, preventing the absorbent sponge 10 from protruding from the top of the mounting groove 102 when squeezed, thus ensuring the stability of the absorbent sponge 10 within the mounting groove 102.

[0027] In this embodiment, the width of the extrusion strip 9 is equal to the width of the mounting groove 102, and the extrusion strip 9 extends into the mounting groove 102. The extrusion strip 9 is located on the right side of the scraper 1001. When the hydraulic rod 4 extends and retracts to its maximum length, the water-absorbing sponge 10 is in a state of maximum compression, which facilitates the extrusion of water adsorbed in the water-absorbing sponge 10.

[0028] like Figure 6 and Figure 7 As shown in this embodiment, a drainage groove 103 is provided at the lower left end of the drying oven 1, and a sealing plug 501 is fixedly provided at the bottom right side surface of the sealing door 5. The sealing plug 501 matches the drainage groove 103. When the sealing door 5 is attached to the left end of the drying oven 1, the sealing door 5 and the left end opening of the drying oven 1 are connected in an airtight manner. At this time, the sealing plug 501 on the sealing door 5 is embedded in the drainage groove 103 to seal the drainage groove 103.

[0029] By setting a sealing door 5 and a sealing plug 501, when the sealing door 5 is attached to the left end of the drying chamber 1, the sealing door 5 and the left end opening of the drying chamber 1 are connected in an airtight manner. At the same time, the sealing plug 501 is embedded in the drainage groove 103 to seal the drainage groove 103. This makes the drying chamber 1 form a completely sealed space during the heating and drying process of the electric heating plate 11. Heat and water vapor cannot overflow and dissipate to the outside. The heat is fully utilized inside the chamber, avoiding the problem of large amounts of hot air escaping due to the opening of exhaust vents or poor sealing in traditional equipment. This significantly improves the thermal energy utilization rate and further enhances the energy-saving effect of the equipment.

[0030] In this embodiment, the bottom surface of the scraper 1001 is attached to the bottom surface of the mounting groove 102, and the scraper 1001 and the mounting groove 102 are airtightly connected, so that the scraper 1001 can prevent water in the absorbent sponge 10 from entering the mounting groove 102 on the right side of the scraper 1001, and facilitate the water adsorbed in the absorbent sponge 10 to be discharged from the drain groove 103.

[0031] With the scraper 1001 and extrusion strip 9 installed, when the hydraulic rod 4 drives the sealing door 5 and the plate support plate 8 to move to the left for material discharge, the extrusion strip 9 moves to the left synchronously with the plate support plate 8 and squeezes the water-absorbing sponge 10, causing the condensate absorbed in the water-absorbing sponge 10 to be squeezed out. The scraper 1001 blocks the right end of the water-absorbing sponge 10, so that the squeezed condensate is discharged through the drainage groove 103. The squeezing, dehydration and drainage actions of the water-absorbing sponge 10 and the material discharge action of the plate are completed synchronously by the same hydraulic rod 4, without the need for additional independent squeezing and drainage mechanisms, thus improving the continuous operation efficiency of the equipment.

[0032] In this embodiment, support bars 2 are fixedly installed on both the inner and outer sides of the bottom surface of the drying oven 1, and traveling wheels 6 are fixedly installed on both the inner and outer sides of the bottom surface of the sealing door 5. The bottom horizontal height of the support bars 2 is equal to the bottom horizontal height of the traveling wheels 6, and the bottom horizontal height of the support bars 2 is lower than the bottom horizontal height of the hydraulic rod 4. This facilitates the support bars 2 to support the drying oven 1 and the traveling wheels 6 to support the sealing door 5. When the hydraulic rod 4 extends or retracts, and when the sealing door 5 moves, the traveling wheels 6 roll on the ground to ensure the smooth opening and closing of the sealing door 5.

[0033] like Figure 8 As shown in this embodiment, multiple board support plates 801 are fixedly arranged on the upper surface of the board support plate 8 from left to right, and the distance between two adjacent board support plates 801 is adapted to the thickness of the board to be dried.

[0034] By setting up board support plates 801, multiple board support plates 801 are fixedly installed on the upper surface of the board support plate 8, so that the boards to be dried can be placed vertically between two adjacent board support plates 801. The board support plates 801 independently separate and support each board, preventing multiple boards from stacking or sticking together during the drying process. This avoids the problems of water vapor being blocked and uneven heating caused by the accumulation of boards, ensuring that the surface of each board can be fully exposed to the thermal environment inside the drying chamber 1, so that all parts of the board are heated evenly and the moisture evaporates smoothly, thereby improving drying efficiency and drying quality.

[0035] In this embodiment, a vacuum pump 12 is installed through the center of the upper surface of the drying oven 1, and a pressure detection sensor is installed inside the drying oven 1.

[0036] Equipped with a vacuum pump 12 and a pressure sensor, before the heating plate 11 is activated to heat the board, the vacuum pump 12 first evacuates the interior of the drying chamber 1 to a sub-vacuum state based on the feedback signal from the pressure sensor. This reduces the pressure inside the drying chamber 1 and consequently lowers the boiling point of water. Then, the heating plate 11 is activated for heating and drying, allowing the moisture in the board to evaporate quickly at a lower temperature. This achieves low-temperature rapid drying, which not only avoids the problems of cracking, deformation, or surface damage to some heat-sensitive boards caused by high-temperature drying, thus ensuring the drying quality of the boards, but also reduces the need for the heating plate 11 to reach a higher temperature for effective drying due to the lower evaporation temperature, further reducing energy consumption and improving the energy-saving effect of the equipment.

[0037] A method for using an energy-saving building material drying equipment includes the following steps: S1: Activate the hydraulic rod 4 to extend it, causing the sealing door 5 and the plate support plate 8 to extend out of the drying chamber 1. Then, place the plate to be dried vertically on the plate support plate 8 and insert it between two adjacent plate support plates 801. Then, the hydraulic rod 4 is activated to retract, which moves the sealing door 5 toward the drying chamber 1. At the same time, the plate support plate 8 slides along the slide groove 101 until the plate is completely inside the drying chamber 1. At this time, the sealing door 5 closes the left opening of the drying chamber 1, and the sealing plug 501 blocks the drainage groove 103. S2: The inside of the drying chamber 1 is evacuated to a sub-vacuum state by the vacuum pump 12, and then the electric heating plate 11 is started to heat and dry the board. S3: After drying is completed, turn off the electric heating plate 11 and vacuum pump 12. The steam in the drying box 1 condenses and is quickly absorbed by the water-absorbing sponge 10. Start the hydraulic rod 4 again to extend it, which drives the sealing door 5 and the plate support plate 8 to move to the left. The sealing plug 501 is removed from the drain trough 103. At the same time, the extrusion strip 9 moves to the left with the plate support plate 8 and squeezes the water-absorbing sponge 10, so that the water absorbed in the sponge is squeezed out. The squeezed-out water is blocked and guided by the scraper 1001 and discharged through the drainage channel 103. After the board support plate 8 is completely removed from the drying oven 1, the dried board is removed.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
