[0034] The working principle of the device will be described through the working process of the device: first, the object of the device, the waterproof material of the cement, will be briefly described. The waterproof material of the cement has the following characteristics: it often contains solid particles, fibers or fillers, and is easy to deposit at the pipe elbow, causing pipe blockage; it has the characteristics of rapid solidification, and if it stays in the pipe for too long, it will solidify and block the pipe further; it has temperature sensitivity, and the viscosity of the waterproof material of the cement increases sharply at low temperature, which further aggravates the pipe blockage. Pipe blockage greatly affects the spraying efficiency of the waterproof material of the cement, and frequent replacement of the pipe is time-consuming and labor-intensive, which reduces the spraying efficiency and increases the degree of operation complexity. The device is used to significantly reduce the possibility of pipe blockage, thereby improving the spraying efficiency of the waterproof material of the cement.

[0035] Referring to Figures 1-9As shown, when the device is used to spray the waterproof material on the concrete building material, the waterproof material is first poured from the top of the area surrounded by the L-shaped partition plate 11 and the box 1, the power supply of the electric heating frame 2 is turned on to start the electric heating frame 2, the electric heating frame 2 generates heat to heat the waterproof material in the area, thereby reducing the viscosity of the waterproof material, the second pump body 4 is started, the inlet end of the second pump body 4 sucks the waterproof material from the discharge port on the L-shaped partition plate 11 through the third one-way valve 81 and the bottom tee 8, the outlet end of the second pump body 4 pumps out the waterproof material, which passes through the first one-way valve 44, the inner tee 41, the outer straight pipe 5, the outer elbow pipe 51, and finally the outer tee 7 from the spray head 71 to the concrete building material, completing the spraying of the waterproof material.

[0036] It should be noted that the spray head 71 can be opened and closed, which is a prior art and will not be described in detail here. During the spraying process, the worker holds the outer tee 7, opens the spray head 71 and aims it at the concrete building material, and the spraying is completed.

[0037] It should be noted that during the above spraying operation, the electromagnetic valve 43 is in a closed state and the second one-way valve 73 is set, which limits the flow direction of the waterproof material, thereby preventing the waterproof material from flowing out of the inner elbow pipe 42 or the end pipe 72.

[0038] During the above spraying operation, referring to Figure 6 and Figure 7 At this time, the outer straight pipe 5, the outer elbow pipe 51 and the self-cleaning assembly 6 are in normal working condition, that is, the sliding magnetic block 93 is located in the inner ring cavity 53 and the side sliding port 92, thereby limiting the movement of the inner sliding sleeve 9, the waterproof material passes through the inner sliding sleeve 9 in the outer straight pipe 5 and flows normally, at this time, due to the setting of the horizontal stop bar 94, the waterproof material collides with the horizontal stop bar 94 when passing through the inner sliding sleeve 9 and is sheared, breaking the waterproof material that has a tendency to clump due to the increase in viscosity caused by the decrease in temperature, thereby reducing the possibility of subsequent blockage of the outer straight pipe 5 and the outer elbow pipe 51.

[0039] Referring to Figure 8 and Figure 9As shown, at this time, the outer straight pipe 5, the outer elbow pipe 51 and the self-cleaning assembly 6 are in the cleaning working condition, that is, the direction of the current flowing through the electromagnet 62 is changed, so that the magnetic pole of the electromagnet 62 is reversed, and the repulsive force generated by the same magnetic pole pushes the sliding magnetic block 93 out of the inner ring cavity 53, the transverse stop rods 94 arranged on the sliding magnetic block 93 abut against each other, limiting the sliding magnetic block 93 from completely separating from the side sliding port 92, at this time, when the waterproof concrete material passes through the inner sliding sleeve 9 again, it will impact the sliding magnetic block 93 and the transverse stop rods 94, and the generated thrust will promote the inner sliding sleeve 9 to slide in the outer straight pipe 5 and the outer elbow pipe 51, at this time, due to the arrangement of the shovel head 91, the shovel head 91 will shovel off the waterproof concrete material adhering and blocking in the inner wall of the outer straight pipe 5 and the outer elbow pipe 51, so as to achieve the purpose of unblocking and cleaning.

[0040] Since the waterproof concrete material adhering and blocking in the inner wall of the outer straight pipe 5 and the outer elbow pipe 51 may form a ball, it may still remain in the outer elbow pipe 51, at this time, the elastic shaft 33 is pulled, so that the limiting block 34 gives way to the end pipe 72, the end pipe 72 is sleeved on the outer connecting short pipe 31 and abuts against the rubber ring pad 32, and then the elastic shaft 33 is loosened, the limiting block 34 is reset and clamps the end pipe 72, so as to complete the quick sealing connection of the end pipe 72 and the outer connecting short pipe 31. At this time, the first pump body 3 is started, the inlet end of the first pump body 3 will suck the waterproof concrete material heated by the electric heating frame 2 from the discharge port on the L-shaped partition plate 11 through the third one-way valve 81 and the bottom tee pipe 8, the outlet end of the first pump body 3 will pump out the high-temperature waterproof concrete material and pass through the outer connecting short pipe 31, the end pipe 72, the second one-way valve 73 and the outer tee pipe 7 to reach the outer elbow pipe 51, at this time, since the outer elbow pipe 51 is relatively closer to the outlet end of the first pump body 3, the high-temperature waterproof concrete material will impact the sliding magnetic block 93 and the transverse stop rods 94, drive the inner sliding sleeve 9 to return while wrapping the waterproof concrete material remaining in the outer elbow pipe 51 and passing through the transverse stop rods 94, heat the balled waterproof concrete material, so as to reduce the viscosity of the balled waterproof concrete material, the transverse stop rods 94 will crush the balled waterproof concrete material, and finally the balled waterproof concrete material will flow from the outer elbow pipe 51, the outer straight pipe 5, the inner tee pipe 41, the electromagnetic valve 43 and the inner elbow pipe 42 to the top of the waterproof concrete material in the area surrounded by the L-shaped partition plate 11 and the box body 1, complete the deep cleaning of the outer straight pipe 5 and the outer elbow pipe 51, and no waste of waterproof concrete material is generated, when the inner sliding sleeve 9 moves to the flange 52, it stops, at this time, the magnetic poles of the electromagnet 62 and the sliding magnetic block 93 on the side close to each other are opposite, generating an attractive force to suck the sliding magnetic block 93 back into the inner ring cavity 53, so as to complete the resetting of the inner sliding sleeve 9, in the above process, the shovel head 91 on the inner sliding sleeve 9 again slides and shovels the inner wall of the outer straight pipe 5 and the outer elbow pipe 51, further improving the cleaning degree of the inner wall of the outer straight pipe 5 and the outer elbow pipe 51, so that the spraying efficiency of the device is significantly improved.

[0041] The device utilizes the heating of the cement waterproof material by the electric heating frame 2 to reduce the viscosity, and further reduce the possibility of blockage in the outer straight pipe 5 and the outer elbow pipe 51. Since the outer straight pipe 5 or the outer elbow pipe 51 is relatively long, the high-temperature cement waterproof material sprayed from the second pump body 4 will gradually increase in viscosity and cause adhesion. The device utilizes the first pump body 3 to spray the high-temperature cement waterproof material from the end pipe 72 into the outer elbow pipe 51 and the outer straight pipe 5. Since the outer elbow pipe 51 is closer to the outer short pipe 31, the high-temperature cement waterproof material can increase the temperature of the adhered cement waterproof material, thereby improving its flowability, and finally returning to the area surrounded by the L-shaped partition plate 11 and the box 1, thereby avoiding waste and reducing the accumulation of adhered cement waterproof material, thereby significantly reducing the possibility of blockage of the outer straight pipe 5 and the outer elbow pipe 51 due to their length, and further improving the spraying efficiency of the device. The structure is exquisite and easy to operate.

[0042] The device utilizes the magnetic pole of the electromagnet 62 which can be reversed by changing the direction of the current flowing therethrough, thereby controlling the inner sliding sleeve 9 to be in normal working condition or cleaning working condition. In the normal working condition, the cross bar 94 shears the cement waterproof material passing through, breaks the cement waterproof material with a tendency to form clumps, and reduces the possibility of subsequent blockage, thereby prolonging the time of the device in the normal working condition. In the cleaning working condition, the inner sliding sleeve 9 slides in the outer straight pipe 5 and the outer elbow pipe 51, and the spade head 91 scoops off the adhered and blocked cement waterproof material, thereby successfully achieving the purpose of unblocking and cleaning. The reverse sliding of the inner sliding sleeve 9 again slides and scoops the inner wall of the outer straight pipe 5 and the outer elbow pipe 51, and at the same time, heats, breaks and finally introduces the clumped cement waterproof material accumulated in the outer straight pipe 5 and the outer elbow pipe 51 into the area surrounded by the L-shaped partition plate 11 and the box 1, thereby avoiding waste and deeply cleaning the outer straight pipe 5 and the outer elbow pipe 51, thereby significantly improving the subsequent spraying efficiency of the device, and the operation is simple and convenient, and is suitable for popularization and application.
