Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, specifically to a rapid drying device for waterproof construction substrates and waterproof coatings. Background Technology

[0002] Mortar is commonly used as a waterproofing material in basements. When mortar is applied to the basement floor, the basement is often dark and damp due to insufficient lighting, making it difficult for the mortar to dry and solidify quickly. To enable the mortar to dry and solidify quickly and form a waterproof layer, a heated dryer is usually required to heat the basement floor. The principle is to use a blower to blow heated air onto the floor to heat it, and the hot air accelerates the evaporation of moisture in the mortar, allowing it to dry and solidify.

[0003] In the existing technology, because mortar is fluid, if the wind speed is high during the process of spraying hot air onto the mortar surface, the mortar is prone to flow, causing part of the waterproof layer to fall off and resulting in uneven waterproof layer thickness. If the wind speed is low, the mortar is difficult to dry quickly, reducing the drying efficiency and thus increasing the difficulty of drying the mortar.

[0004] Based on this, the present invention designs a rapid drying device for waterproof construction substrates and waterproof coatings to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid drying device for waterproof construction substrates and waterproof coatings, in order to solve the problems mentioned in the background art. Due to the fluidity of mortar, if the air velocity is high during the process of spraying hot air onto the mortar surface, the mortar is prone to flow, causing part of the waterproof layer to fall off and resulting in uneven waterproof layer thickness. If the air velocity is low, the mortar is difficult to dry quickly, reducing the drying efficiency and thus increasing the difficulty of drying the mortar.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid drying device for waterproof construction substrate and waterproof coating, comprising:

[0013] During the startup of the pumping component, air enters the heating chamber through the channel. As the air circulates, it carries away the moisture on the surface of the waterproof layer, thus assisting in drying the surface of the waterproof layer and accelerating its solidification.

[0023] A connecting plate is fixedly connected to the partition plate, with its bottom end extending to the bottom of the housing, and is also fixedly connected to the heating box.

[0024] Two sealing plates are symmetrically and slidably connected to the two side walls of the partition.

[0025] A pushing assembly for pushing a sealing plate to move it downwards to insulate the hot air between the two L-shaped extension plates.

[0026] As a further aspect of the present invention, the driving component includes:

[0027] A drive plate, which is fixedly connected to the side wall of the sealing plate;

[0028] A drive slot is formed on the drive plate;

[0029] A pusher frame, the top end of which is fixedly connected to the top end of an L-shaped extension plate, and the bottom end of which is slidably connected within the drive groove.

[0030] As a further aspect of the present invention, the pumping assembly includes:

[0031] The suction pipe has one end fixedly connected to the right side wall of the heating box, and the other end fixedly connected to the suction end of the pump body inside the trolley.

[0032] An exhaust pipe, one end of which is fixedly connected to the exhaust end of the pump body inside the trolley, and the other end of which is fixedly connected to a diversion box, the diversion box being fixedly connected to the left side wall of the trolley;

[0033] Several diversion pipes, one end of which is fixedly connected to the diversion box, and the other end of which is fixedly connected to the housing corresponding to the position of the L-shaped extension plate.

[0034] As a further embodiment of the present invention, the drive groove has an inclined groove and a straight groove.

[0035] As a further aspect of the present invention, it also includes:

[0036] An L-shaped drain plate is fixedly connected inside the heating box, with its bottom end positioned above the heating plate.

[0037] As a further aspect of the present invention, it also includes:

[0038] Upper corrugated plate, which is fixedly connected to the bottom of the L-shaped drainage plate;

[0039] The lower wave plate is fixedly connected to the top of the heating plate, and the lower wave plate is offset from the upper wave plate.

[0040] As a further embodiment of the present invention, the shell is a trapezoidal shell.

[0041] As a further embodiment of the present invention, the length between the wheel hubs on both sides of the trolley is less than the length of the shell.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] 1. This invention, by setting up an arc-shaped guide plate and an arc-shaped baffle, allows air to enter the heating box along the arc-shaped guide plate, which is conducive to promoting air circulation at the mortar and allowing the moisture on the mortar surface to evaporate quickly. Furthermore, by setting up a heating plate, on the one hand, the air inside the heating box is heated to provide a hot air source for the jet box, and on the other hand, the air at the location of the mortar is heated to increase the air temperature, thereby facilitating the drying of the wet mortar, causing the mortar surface to solidify, reducing the fluidity of the mortar, and thus helping to reduce the problem of uneven waterproof layer thickness caused by hot air blowing on the mortar.

[0044] 2. This invention uses a reflective sensor. If the reflectivity of the detected area is lower than a specified value, the L-shaped extension plate moves closer to the heating box to increase the nozzle diameter and reduce the wind speed of the hot air. When the wet mortar enters directly below the L-shaped extension plate, the nozzle diameter at the corresponding position is at its maximum and the wind speed is at its minimum. This reduces the problem of uneven waterproof layer thickness caused by the hot air blowing on the mortar. As the trolley moves, the mortar gradually moves to the right side of the shell. During the movement, the mortar surface gradually dries, reducing its fluidity. At the same time, the nozzle diameter gradually decreases and the wind speed of the hot air gradually increases, improving airflow and thus allowing the mortar to dry quickly.

[0045] 3. By setting up partitions and sealing plates, the present invention activates the pushing component during the movement of the L-shaped extension plates toward the side wall of the heating box, causing the sealing plate at the corresponding position to move downward, thereby isolating the hot air between the two L-shaped extension plates, thus benefiting the concentration of hot air to dry the humid area.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Please see Figures 1-6 This invention provides a rapid drying device for waterproof construction substrates and waterproof coatings, comprising:

[0056] A trolley 1, with a heating box 2 fixedly connected to the left end of the trolley 1;

[0057] Heating plate 3 is fixedly connected to the bottom port of heating box 2;

[0058] The jet box is fixedly connected to the right side wall of the heating box 2;

[0059] The pumping assembly is used to pump the hot air in the heating box 2 into the jet box, so that the jet box sprays hot air onto the road surface to accelerate the drying of the waterproof layer.

[0060] The arc-shaped diversion plate 4 is fixedly connected to the left end of the bottom port of the heating box 2. The arc-shaped diversion plate 4 has a horizontal section and an arc-shaped section.

[0061] Arc-shaped baffle 5 is fixedly connected to the left end of the bottom port of the heating box 2. The side wall of the arc-shaped baffle 5 is fixedly connected to the heating plate 3. A gap is left between the arc-shaped baffle 5 and the arc-shaped guide plate 4 to form a channel 6.

[0062] During the startup of the pumping component, air enters the heating chamber 2 through channel 6. During the air circulation, the moisture on the surface of the waterproof layer is carried away to assist in drying the surface of the waterproof layer and accelerate the solidification of the surface of the waterproof layer.

[0063] Specifically, in the existing technology, due to the fluidity of mortar, if the wind speed is high during the process of spraying hot air onto the mortar surface, the mortar is prone to flow, causing some of the waterproof layer to fall off and resulting in uneven waterproof layer thickness. If the wind speed is low, the mortar is difficult to dry quickly, reducing the drying efficiency and thus increasing the difficulty of drying the mortar. This technical solution can solve the above problems. The specific operation is as follows: After the mortar is applied to the basement, the trolley 1 is pushed so that the heating box 2 at the left end of the trolley 1 passes through the mortar area first. By activating the pumping component, the air pressure of the heating box 2 is increased, allowing outside air to enter from the left end of the heating box 2. Under the action of the arc-shaped diversion plate 4, the air first flows along the horizontal section to promote air flow at the mortar, which is conducive to promoting the evaporation of moisture on the mortar surface.

[0064] Then the air enters the heating box 2 through the channel 6. Under the action of the heating plate 3, the air temperature rises to form hot air, which is finally sent into the jet box by the pumping component.

[0065] As the trolley 1 continues to move, the heating plate 3 moves into the mortar area. The heating effect of the heating plate 3 heats the air at the location of the mortar, increases the air temperature, and thus helps to dry the wet mortar, causing the mortar surface to solidify.

[0066] Next, the jetting box moves to the mortar and blows hot air onto the mortar surface. As the moisture on the mortar surface decreases and solidifies, the fluidity of the mortar is reduced, which helps to reduce the problem of uneven waterproof layer thickness caused by hot air blowing on the mortar.

[0067] As a further embodiment of the present invention, the jet box includes:

[0068] The shell 7 is fixedly connected to the right side wall of the heating box 2 by brackets on both sides;

[0069] Two mounting plates 8 are symmetrically and fixedly connected to the two side walls of the housing 7, and the mounting plates 8 are fixedly connected to the heating box 2;

[0070] Several L-shaped extension plates 9 are slidably connected to the inner wall of the housing 7 in an array;

[0071] Several sealing components are located between two L-shaped extension plates 9 to separate the hot air between the two L-shaped extension plates 9;

[0072] Several reflective sensors 10 are fixedly connected to the bottom right end of the heating box 2, corresponding to the positions of the L-shaped extension plate 9.

[0073] Several push cylinders 11 are arrayed and fixedly connected to the top of the housing 7, and the ends of the telescopic rods of the push cylinders 11 are fixedly connected to the L-shaped extension plates 9 at the corresponding positions.

[0074] Yes, due to the unevenness of the ground during the mortar application process, the mortar thickness varies in different locations. The thicker the mortar, the more moisture it contains, and the more difficult it is to dry. If the mortar surface still has a lot of moisture when the air jet passes through it, the mortar is prone to flow when the hot air blows it, causing parts of the waterproof layer to peel off and resulting in uneven waterproof layer thickness. This technical solution can solve the above problems. The specific operation is as follows: Since water is translucent, the wetter the mortar, the lower its reflectivity, and vice versa. By setting a reflective sensor 10, after the mortar leaves the heating plate 3 area, the reflective sensor 10 performs zone detection on the mortar. If the reflectivity of the detected area is lower than the specified value, the corresponding push cylinder 11 is activated, so that the extension rod of the push cylinder 11 pushes the L-shaped extension plate 9, so that the L-shaped extension plate 9 moves closer to the heating box 2 to increase the spray nozzle diameter and reduce the wind speed of the hot air. On the one hand, this helps to reduce the problem of uneven waterproof layer thickness when the hot air blows on the mortar, and on the other hand, it prolongs the time when the hot air passes through.

[0075] After the mortar with high humidity enters directly below the L-shaped extension plate 9, the push cylinder 11 is activated, causing the extension rod of the push cylinder 11 to pull the L-shaped extension plate 9, which moves the L-shaped extension plate 9 into the housing 7 to reduce the nozzle diameter and gradually increase the wind speed of the hot air. Since the trolley 1 is always in a moving state, by adjusting the pulling speed of the push cylinder 11, the pulling speed of the push cylinder 11 is made to be the same as the pushing speed, so that the wet mortar will always be in the L-shaped extension plate 9.

[0076] In other words, after the wet mortar enters directly below the L-shaped extension plate 9, the nozzle diameter at the corresponding position is at its maximum and the wind speed is at its minimum to reduce the problem of uneven waterproof layer thickness caused by hot air blowing on the mortar. As the trolley 1 moves, the mortar gradually moves to the right side of the shell 7. During the movement, the mortar surface gradually becomes drier, which reduces its fluidity. At the same time, the nozzle diameter gradually decreases and the wind speed of the hot air gradually increases, which improves airflow and allows the mortar to dry quickly.

[0077] It should be noted that the casing 7 is trapezoidal in order to increase the injection speed.

[0078] As a further embodiment of the present invention, the sealing assembly includes:

[0079] The partition 12 is fixedly connected to the inner wall of the housing 7. The bottom end of the partition 12 is away from the bottom end of the housing 7. The two sides of the partition 12 are slidably connected to two L-shaped extension plates 9 at corresponding positions.

[0080] Connecting plate 13 is fixedly connected to partition plate 12. The bottom end of connecting plate 13 extends to the bottom of housing 7. Connecting plate 13 is fixedly connected to heating box 2.

[0081] Two sealing plates 14 are symmetrically and slidably connected to the two side walls of the partition plate 12.

[0082] A pushing component is used to push the sealing plate 14 to move the sealing plate 14 downward to isolate the hot air between the two L-shaped extension plates 9;

[0083] Specifically, by setting a sealing component, as the L-shaped extension plate 9 moves toward the side wall of the heating box 2, the pushing component is activated, causing the sealing plate 14 at the corresponding position to move downward, thereby isolating the hot air between the two L-shaped extension plates 9, thus benefiting the concentration of hot air to dry the humid area.

[0084] As one possible implementation of the driving component, the driving component includes:

[0085] Drive plate 15, drive plate 15 is fixedly connected to the side wall of sealing plate 14;

[0086] Drive slot 16 is formed on drive board 15;

[0087] The top end of the push frame 17 is fixedly connected to the top end of the L-shaped extension plate 9, and the bottom end of the push frame 17 is slidably connected in the drive groove 16.

[0088] Specifically, by setting up the drive plate 15 and the drive groove 16, as the L-shaped extension plate 9 moves toward the side wall of the heating box 2, the pusher 17 slides along the drive groove 16. Under the action of the drive groove 16, the sealing plate 14 moves downward, thereby isolating the hot air between the two L-shaped extension plates 9, thus benefiting the concentration of hot air to dry the humid area.

[0089] The drive groove 16 has an inclined groove 1601 and a straight groove 1602. During the process of the L-shaped extension plate 9 moving towards the side wall of the heating box 2, the push frame 17 first moves along the inclined groove 1601, causing the sealing plate 14 to move downward, isolating the hot air between the two L-shaped extension plates 9, so that the wind speed in other parts remains unchanged. Then the push frame 17 slides along the straight groove 1602, causing the spray nozzle diameter to continue to increase, and the wind speed to decrease, so as to reduce the problem of uneven thickness of the waterproof layer when the hot air blows the mortar.

[0090] As a further embodiment of the present invention, the pumping assembly includes:

[0091] The suction pipe 18 has one end fixedly connected to the right side wall of the heating box 2, and the other end fixedly connected to the suction end of the pump body inside the trolley 1.

[0092] The exhaust pipe 19 has one end fixedly connected to the exhaust end of the pump body inside the trolley 1, and the other end fixedly connected to the diversion box 20, which is fixedly connected to the left side wall of the trolley 1.

[0093] Several diversion pipes 21, one end of which is fixedly connected to the diversion box 20, and the other end is fixedly connected to the housing 7 at the position corresponding to the L-shaped extension plate 9;

[0094] Specifically, by setting up a distribution box 20, the pump body in the trolley 1 sends the hot air from the heating box 2 into the distribution box 20. The hot air is then evenly distributed to the space where each L-shaped extension plate 9 is located through the distribution box 20 and the distribution pipe 21, which helps to make the wind speed more uniform and the mortar drying more evenly.

[0095] As a further embodiment of the present invention, it also includes:

[0096] L-shaped guide plate 22, the L-shaped guide plate 22 is fixedly connected inside the heating box 2, and the bottom end of the L-shaped guide plate 22 is located above the heating plate 3;

[0097] Specifically, by setting up an L-shaped air guide plate 22, the air can move along the surface of the heating plate 3 after entering the heating box 2, thereby improving the conversion efficiency, making full use of the heating efficiency of the heating plate 3, and ensuring that the air is fully heated.

[0098] As a further embodiment of the present invention, it also includes:

[0099] Upper wave plate 23 is fixedly connected to the bottom of L-shaped drainage plate 22;

[0100] The lower wave plate 24 is fixedly connected to the top of the heating plate 3, and the lower wave plate 24 is offset from the upper wave plate 23.

[0101] Specifically, by setting up an upper wave plate 23 and a lower wave plate 24, air is allowed to flow along the wave groove formed by the upper wave plate 23 and the lower wave plate 24, thereby allowing the air to be fully heated.

[0102] As a further embodiment of the present invention, the length between the wheel hubs on both sides of the trolley 1 is less than the length of the housing 7;

[0103] Specifically, since the length between the wheel hubs on both sides of the trolley 1 is less than the length of the shell 7, the wheel hubs are always in the already dry area, preventing the wheel hubs from driving into the undried area and causing damage to the waterproof layer.

[0104] Working principle: After the mortar is applied to the basement, the trolley 1 is pushed so that the heating box 2 at the left end of the trolley 1 passes through the mortar area. By activating the pumping component, the air pressure in the heating box 2 is increased, allowing outside air to enter from the left end of the heating box 2. Under the action of the arc-shaped diversion plate 4, the air flows along the horizontal section first to promote air flow in the mortar area, which is conducive to promoting the evaporation of moisture on the mortar surface.

[0105] Then the air enters the heating box 2 through the channel 6. Under the action of the heating plate 3, the air temperature rises to form hot air, which is finally sent into the jet box by the pumping component.

[0106] As the trolley 1 continues to move, the heating plate 3 moves into the mortar area. The heating effect of the heating plate 3 heats the air at the location of the mortar, increases the air temperature, and thus helps to dry the wet mortar, causing the mortar surface to solidify.

[0107] Next, the jetting box moves to the mortar and blows hot air onto the mortar surface. As the moisture on the mortar surface decreases and solidifies, the fluidity of the mortar is reduced, which helps to reduce the problem of uneven waterproof layer thickness caused by hot air blowing on the mortar.
