Description

Technical Field

[0001] This utility model relates to the field of wet spraying technology for refractory materials, and in particular to a wet spraying device for refractory materials. Background Technology

[0002] A wet spraying device for refractory materials is a specialized device for spraying mixed refractory materials onto the surface of equipment. This device typically includes components such as a mixer, silo, and air compressor. It enables efficient and low-dust construction, and the refractory materials can quickly solidify on the equipment surface under the action of a accelerator, avoiding material rebound, thereby saving materials and reducing costs.

[0003] Common wet spraying devices for refractory materials have relatively simple structures and limited nozzle length, making them unsuitable for spraying the inner walls of tubular objects and lacking practicality. Therefore, we propose a wet spraying device suitable for refractory materials. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Common wet spraying devices for refractory materials have relatively simple structures and limited nozzle length, making them unsuitable for spraying the inner walls of tubular objects and thus lacking practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wet spraying device for refractory materials includes an operating table, a storage tank installed on the top of the operating table near the back, and a wet spraying component installed on the top of the operating table near the front.

[0007] The spraying assembly includes a bracket, which is fixedly installed on the top of the operating table. A first roller is rotatably connected to the inner side of the bracket near the bottom. A second roller is installed on the inner side of the bracket and at the top of the first roller. A drive assembly is installed on the left side of the bracket. A flexible hose is sleeved around the first roller, and a cable is sleeved around the second roller. The spraying assembly is installed at the end of the flexible hose and cable away from the bracket. A counterweight assembly is installed at the top of the spraying assembly near the back.

[0008] As a preferred embodiment of this utility model, a support bracket is slidably connected to the inside of the operating table near the front, and a fixing rod is threadedly connected to the bottom of the operating table corresponding to the support bracket.

[0009] The technical advantages of adopting the above-mentioned further solution are: the support bracket can support the inclined tubular object, improving the ease of use; and the support bracket can be fixed by rotating the fixing rod, improving the stability of use.

[0010] As a preferred embodiment of this utility model, an air inlet pipe is installed at the top of the storage tank, and the end of the hose away from the humidification component is connected to the storage tank.

[0011] The technical effect of adopting the above-mentioned further solution is that the external air pump inputs high-pressure gas into the storage tank through the air inlet pipe, and uses the principle of air pressure to push the material in the storage tank into the hose.

[0012] As a preferred embodiment of this utility model, the bracket is made of metal and is U-shaped.

[0013] As a preferred embodiment of this utility model, the driving assembly includes a driving gear, which is rotatably connected to the bracket. Both the top and bottom of the driving gear are meshed with driven gears, and the two driven gears are fixedly connected to the first roller shaft and the second roller shaft, respectively.

[0014] The technical effect of adopting the above-mentioned further solution is that by rotating the drive gear, the driven gear can be driven to rotate, thereby driving the first roller shaft and the second roller shaft to rotate, so as to tighten or loosen the hose and cable.

[0015] As a preferred embodiment of this utility model, the spraying assembly includes a fixed base, which is connected to a hose. Several sliding rods are slidably connected to the periphery of the fixed base. A roller assembly is rotatably connected to the end of each sliding rod away from the fixed base. A screw is threadedly connected to the bottom of the fixed base corresponding to the sliding rod. A spray head is installed near the center of the bottom of the fixed base.

[0016] The technical effect of adopting the above-mentioned further solution is that the slide rod can drive the roller assembly to fit against the inner wall of the tubular object according to the diameter of the tubular object, which can reduce the friction between the fixed seat and the tubular object. The slide rod can be positioned by rotating the screw, which improves the ease of use.

[0017] As a preferred embodiment of this utility model, the cable is fixedly connected to the second roller shaft, and the end of the cable away from the second roller shaft is fixedly connected to the fixed base.

[0018] The technical advantage of adopting the above-mentioned further solution is that by fixing the cable to the second roller shaft, the fixed seat can be pulled to move inside the tubular object, thereby achieving the purpose of mobile spraying and improving ease of use.

[0019] As a preferred embodiment of this utility model, the counterweight assembly includes a sleeve rod, which is welded to a fixed base, and a plurality of counterweight blocks are sleeved around the sleeve rod.

[0020] The technical effect of adopting the above-mentioned further solution is that the weight of the fixed seat can be increased by the counterweight, so that it can slide from the top of the tube to the bottom more easily, thus improving the ease of use.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] In this invention, the design of the operating table, storage tank, and spraying assembly allows the tubular object to be placed at an angle against the support. The fixing seat is then inserted from the top of the tubular object and allowed to slowly slide down to the bottom. The sliding rod is pulled out, causing the roller assembly to fit against the inner wall of the tubular object. Finally, the drive gear is rotated, causing the first and second roller shafts to rotate via the driven gear, slowly pulling the fixing seat upwards and spraying moisture during the process. This effectively continues the spraying operation on the inner wall of the tubular object, greatly improving its practicality. Attached Figure Description

[0032] Example 1

[0033] like Figure 1-4 As shown, this utility model provides a technical solution: a wet spraying device for refractory materials, including an operating table 1, a storage tank 2 installed at the top of the operating table 1 near the back, a spraying mechanism 3 installed at the top of the operating table 1 near the front, the spraying mechanism 3 including a bracket 301, the bracket 301 being fixedly installed at the top of the operating table 1, a first roller 302 being rotatably connected to the inner side of the bracket 301 near the bottom, a second roller 303 being installed on the inner side of the bracket 301 and at the top of the first roller 302, a drive assembly 304 being installed on the left side of the bracket 301, a hose 305 being sleeved around the first roller 302, a cable 306 being sleeved around the second roller 303, a spraying assembly 307 being installed at the end of the hose 305 and the cable 306 away from the bracket 301, and a counterweight assembly 308 being installed at the top of the spraying assembly 307 near the back.

[0034] Example 2

[0035] like Figure 1-4As shown, a support bracket 101 is slidably connected to the inside of the operating table 1 near the front. A fixing rod 102 is threadedly connected to the bottom of the operating table 1 corresponding to the support bracket 101. The support bracket 101 can support tilted tubular objects, improving ease of use. The support bracket 101 can be fixed by rotating the fixing rod 102, improving stability. An air inlet pipe 201 is installed at the top of the storage tank 2. The end of the hose 305 away from the spraying component 307 is connected to the storage tank 2. An external air pump inputs high-pressure gas into the storage tank 2 through the air inlet pipe 201, and uses air pressure to force the material in the storage tank 2 into the hose 305. The bracket 301 is... Made of metal and U-shaped, the drive assembly 304 includes a drive gear 3041 rotatably connected to the bracket 301. Driven gears 3042 are meshed at both the top and bottom of the drive gear 3041. The two driven gears 3042 are fixedly connected to the first roller shaft 302 and the second roller shaft 303, respectively. Rotating the drive gear 3041 drives the driven gears 3042, which in turn drives the first roller shaft 302 and the second roller shaft 303, thus tightening or loosening the hose 305 and cable 306. The spraying assembly 307 includes a fixing seat 3071, which is connected to the hose 305. A series of sliding rods 3072 are slidably connected to the periphery of the fixed base 3071. A roller assembly 3073 is rotatably connected to the end of each sliding rod 3072 away from the fixed base 3071. A screw 3074 is threadedly connected to the bottom of the fixed base 3071 corresponding to the sliding rods 3072. A nozzle 3075 is installed near the center of the bottom of the fixed base 3071. The sliding rods 3072 can drive the roller assembly 3073 to conform to the inner wall of the tubular object according to its diameter, reducing the friction between the fixed base 3071 and the tubular object. Rotating the screw 3074 can position the sliding rods 3072, improving ease of use. The nozzle 3075 can spray water from the hose 305. Material is sprayed out, and cable 306 is fixedly connected to the second roller shaft 303. The end of cable 306 away from the second roller shaft 303 is fixedly connected to the fixed seat 3071. Through the fixed connection between cable 306 and the second roller shaft 303, the fixed seat 3071 can be pulled to move inside the tubular object, thereby achieving the purpose of moving and spraying, improving ease of use. The counterweight component 308 includes a sleeve rod 3081, which is welded to the fixed seat 3071. Several counterweight blocks 3082 are sleeved around the sleeve rod 3081. The counterweight blocks 3082 can increase the weight of the fixed seat 3071, allowing it to slide smoothly from the top of the tubular object to the bottom, improving ease of use.

[0036] The working process of this utility model is as follows: When using a wet spraying device suitable for refractory materials to spray the inner wall of a tubular structure that is open at both ends, firstly, the tubular structure is leaned against the support 101. The fixing seat 3071 is inserted into the tubular structure from the top, and under the action of the counterweight 3082, the fixing seat 3071 slides down to the bottom of the tubular structure. The slider is pushed outward from one end of the bottom of the tubular structure to make it fit against the inner wall of the tubular structure. Then, the screw 3074 is rotated to complete the fixing of the slider 3072. At this time, the external air pump delivers air through the air inlet pipe 201. High-pressure gas enters the storage tank 2, and the gas pressure forces the material inside the storage tank 2 into the hose 305. The material is then sprayed out through the nozzle 3075 to wet the inner wall of the tubular object. During this process, the drive gear 3041 is rotated, which in turn drives the first roller shaft 302 and the second roller shaft 303 to rotate through the driven gear 3042. This simultaneously tightens the hose 305 and the cable 306, causing the fixed base 3071 to slowly move upwards for mobile spraying. This effectively continues to wet the inner wall of the tubular object, greatly improving its practicality.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
