[0040] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0041] The following describes the noun part of the waterproof coating heating barrel 100 and the waterproof coating spraying equipment according to the present application with reference to the accompanying drawings.

[0042] like Figures 1 to 4 As shown, a specific embodiment of the present application provides a waterproof coating heating barrel 100, comprising a barrel body 2 and a heating element 1, wherein a barrel cavity for accommodating the waterproof coating is formed inside the barrel body 2 and is provided with a feed port 3 and a discharge port 4; the heating element 1 is arranged in the barrel cavity and divides the barrel cavity into a first cavity 5 and a second cavity 6, and a feed hole 7 is provided on the heating element 1, the feed hole 7 connects the first cavity 5 and the second cavity 6, the feed port 3 is connected to the first cavity 5, and the discharge port 4 is connected to the second cavity 6.

[0043] When spraying waterproof coatings for waterproof construction in winter, it is usually necessary to heat the waterproof coatings to increase fluidity so that they can be smoothly sprayed to the waterproof construction area, especially for polyurethane coatings with poor fluidity at low temperatures. In the present application, first, the polyurethane coating is poured into the first cavity 5 from the feed port 3, and then the polyurethane coating passes through the feed hole 7 on the heating element 1 and enters the second cavity 6, while being heated by the heating element 1 to increase fluidity, and finally, the polyurethane coating with greater fluidity flows out from the discharge port 4. In this process, the polyurethane coating must be heated by the heating element 1 before being sprayed out from the discharge port 4, so as to ensure that the waterproof coating flowing out of the discharge port 4 is evenly heated, thereby avoiding overburning of part of the polyurethane coating and affecting the performance of the polyurethane coating.

[0044] Among them, the waterproof coating includes polyurethane coating and other coatings used for waterproof construction with low fluidity in cold areas. Those skilled in the art can selectively apply the waterproof coating heating barrel 100 to the winter construction of various waterproof coatings.

[0045] Preferably, the discharge port 4 is located at the bottom end of the barrel body 2, and the feed port 3 is located at the top end of the barrel body 2, so that the waterproof coating flows from the feed port 3 to the discharge port 4 under the action of gravity and passes through the heating element 1, thereby avoiding the situation where the waterproof coating has low fluidity and cannot flow from the feed port 3 to the discharge port 4.

[0046] Preferably, the heating element 1 is arranged close to the discharge port 4 so that the volume of the first cavity 5 is larger than the volume of the second cavity 6, so that the first cavity 5 can temporarily store more waterproof coating, thereby reducing the frequency of adding waterproof coating to the waterproof coating heating barrel 100 in a single construction.

[0047] In some embodiments, the barrel body 2 includes a vertical portion 21 and a funnel portion 22, wherein the vertical portion 21 extends in a vertical direction, and the top and bottom ends of the vertical portion 21 are both open, and the top of the vertical portion 21 serves as a feed port 3; the large diameter end of the funnel portion 22 is connected to the bottom end of the vertical portion 21, and the small diameter end of the funnel portion 22 serves as a discharge port 4, and the heating element 1 is disposed in the funnel portion 22.

[0048] Specifically, the vertical portion 21 is a cylindrical member with upper and lower openings, and the funnel portion 22 is a semi-elliptical member. The outer peripheral wall of the large diameter end of the funnel portion 22 is formed with an annular groove, and the inner peripheral wall of the bottom end of the vertical portion 21 is plugged into the annular groove, thereby realizing a detachable connection between the vertical portion 21 and the funnel portion 22, and thus facilitating disassembly and assembly for transportation and cleaning. By arranging the heating element 1 at a position close to the discharge port 4 to directly contact the waterproof coating, it is not only beneficial to the lightweight and simplification of the mechanism in the barrel, but also because the heating element 1 is surrounded by the waterproof coating, it is more conducive to heat conduction than the heating element 1 arranged on the periphery of the waterproof coating.

[0049] Furthermore, the heating element 1 is a disc-shaped component, and the outer diameter of the heating element 1 matches the inner diameter of the funnel portion 22, so as to prevent the waterproof coating from flowing from the gap between the heating element 1 and the funnel portion 22 into the second cavity 6. There are multiple feeding holes 7 on the heating element 1 and they are arranged at intervals. The size and number of the feeding holes 7 can be set as needed. The size and number of the feeding holes 7 determine the amount of feeding through the feeding holes 7 per unit time. In fact, the amount of feeding needs to match the heating speed of the heating element 1, so as to ensure that the waterproof coating passing through the feeding holes 7 has good fluidity. As for the detailed parameters, they need to be set according to actual operations or multiple experiments. This setting process is well known to those skilled in the art and does not belong to the core improvement part of this application, so it will not be repeated here.

[0050] Those skilled in the art will appreciate that the present application is not limited to the above-mentioned structural forms of the barrel body 2 and the heating element 1, but may also be other structural forms such as a cube and a special-shaped body, and other structural forms should also fall within the protection scope of the present application.

[0051] Preferably, the center of the heating plate is located on the axis of the funnel portion 22, the feed hole 7 is a strip hole, and the central axes of the multiple feed holes 7 are parallel to each other, and the length of the feed hole 7 near the center of the heating element 1 is greater than the length of the feed hole 7 far from the center of the heating element 1. After passing through the feed hole 7 near the center of the heating element 1, the waterproof coating can directly fall to the discharge port 4 for discharge, while after passing through the feed hole 7 far from the center of the heating element 1, it needs to slide to the discharge port 4 to be discharged. Therefore, the above-mentioned setting is used to reduce the amount of the feed hole 7 far from the center of the heating element 1, thereby preventing the waterproof coating from accumulating at the center far from the heating element 1 due to slow sliding, thereby affecting the discharge speed of the discharge port 4.

[0052] Furthermore, the area of ​​the cross section of the feed hole 7 parallel to the horizontal plane decreases toward the discharge port 4, that is, the hole wall of the feed hole 7 is inclined in the vertical direction, thereby slowing down the falling speed of the waterproof coating, thereby ensuring that the waterproof coating can be fully heated when passing through the feed hole 7.

[0053] In some embodiments, a mounting seat 8 is provided in the barrel body 2, and the mounting seat 8 is used to install the heating element 1. A line tube 9 passing through the barrel wall of the barrel body 2 is provided at the bottom of the mounting seat 8. A line hole connected to the line tube 9 is opened on the mounting seat 8, and the line of the heating element 1 passes through the line hole and the line tube 9 to be connected to the power supply.

[0054] Specifically, there are two mounting seats 8 and they are arranged symmetrically, the top surfaces of the two mounting seats 8 form a mounting horizontal plane, and the bottom surface of the heating element 1 is placed on the mounting horizontal plane and is fastened. The line pipe 9 passes through the bottom wall of the barrel 2 in the vertical direction, and an electrode is provided at the bottom of the heating element 1. When installing the heating element 1, the electrode is inserted into the line pipe 9 to facilitate the connection between the line and the power supply. After the line of the heating element 1 passes through the line pipe 9 and is connected to the power supply, a sealing member is filled in the line pipe 9 for heat insulation, thereby preventing the external environment from affecting the heating efficiency.

[0055] In some embodiments, the waterproof coating heating barrel 100 also includes an electrical control box 16, which is equipped with a temperature controller, a voltage and current display light, and a hydraulic circuit breaker. The temperature controller is electrically connected to the heating element 1 and is used to adjust the heating temperature of the heating element 1.

[0056] Specifically, the electric control box 16 is arranged at the bottom of the barrel body 2, the electrodes of the heating element 1 are connected to the electric control box 16, and the thermostat is electrically connected to the heating element 1 through the electric control box 16 to automatically adjust the temperature of the heating element 1, thereby avoiding the heating temperature being too high to affect the performance of the waterproof coating, or avoiding the heating temperature being too low to increase the fluidity of the waterproof coating.

[0057] Furthermore, the electric control box 16 is provided with a voltage and current display light and a hydraulic circuit breaker, thereby increasing leakage protection to improve the safety of the waterproof coating heating barrel 100.

[0058] It should be noted that the structures and principles of the temperature controller, voltage and current display lights and hydraulic circuit breaker are well known to people in this field, and do not belong to the core improvement part of this application, so they will not be repeated here.

[0059] Preferably, the discharge port 4 is sequentially connected with a quick-release joint 10, a material guide tube 11 and a quick-release tube 12, and the quick-release tube 12 is used to connect a high-pressure airless sprayer. The quick-release joint 10, the material guide tube 11 and the quick-release tube 12 facilitate the disassembly and cleaning of the waterproof coating heating barrel 100 and the high-pressure airless sprayer.

[0060] Preferably, the outer wall of the barrel body 2 is provided with a handle 13 and a pallet 14 for assembling a high-pressure airless sprayer. The handle 13 is provided to facilitate the transportation of the barrel body 2, and the pallet 14 is provided to facilitate the assembly of the high-pressure airless sprayer, thereby increasing the convenience of using the waterproof coating heating barrel 100.

[0061] Preferably, a base frame 15 with a plurality of universal wheels is provided at the bottom of the barrel body 2, and the barrel body 2 is moved by providing the universal wheels, thereby facilitating the overall movement of the waterproof coating heating barrel 100.

[0062] The specific embodiment of the present application also provides a waterproof coating spraying device, including a waterproof coating heating barrel 100 and a high-pressure airless sprayer, wherein the waterproof coating heating barrel 100 is used to heat the waterproof coating, and the high-pressure airless sprayer is used to communicate with the discharge port 4 of the waterproof coating heating barrel 100 and spray the heated waterproof coating. Since the waterproof coating spraying device adopts all embodiments of the waterproof coating heating barrel 100, the waterproof coating spraying device has all the beneficial effects brought by the waterproof coating heating barrel 100.
