Description

Technical Field

[0001] The invention relates to the technical field of fireproof material spraying, in particular to a fireproof material filling device and a use method thereof. Background Art

[0002] When natural gas pipelines are laid through walls, through holes will be left on the wall surface. When a fire occurs on one side of the wall, the fire will spread to the other side of the wall through the gap between the pipeline and the through hole, thereby expanding the disaster. Therefore, it is necessary to fill the annular gap between the pipeline and the through hole with fireproof materials. The fireproof materials commonly used for filling through holes in walls mainly include organic fireproof materials, inorganic fireproof materials and fireproof bags, among which fireproof coatings are commonly used organic fireproof materials. When the annular gap between the pipeline and the through hole is between 15mm and 50mm, fireproof coatings must be used for filling.

[0003] When filling the annular gap between the pipe and the through hole with fire-retardant coating, a sleeve is first installed inside the through hole, and after the pipe is inserted into the sleeve, the position of the pipe is fixed by a bracket so that the pipe and the sleeve are coaxially arranged, and then the fire-retardant material is filled in the annular gap between the pipe and the sleeve. When spraying the fire-retardant coating on the annular gap, the staff usually fills it with a handheld spray gun. Under the obstruction of the pipe, the staff needs to constantly adjust their position along the circumference of the pipe, resulting in the inability to ensure that the spray gun moves in a fixed trajectory during spraying, thereby affecting the uniformity of the spraying thickness. After the paint layer is dried, the over-thick or over-thin areas need to be polished or scraped, and then re-sprayed until the coating thickness is uniform and meets the requirements, which seriously limits the work efficiency of the staff. In view of the above problems, there are better solutions in the prior art. A circular track is installed on the pipe, and the spray gun is installed on the circular track. Driven by a power source, the spray gun rotates around the pipe during operation, and the staff does not need to adjust their position, which greatly reduces the work intensity during spraying. However, the following problems still exist: thick steel structure fire retardant coating is a special fire retardant coating. Due to the thick coating and large amount of usage, it is easy to precipitate due to factors such as excessive pigment-to-base ratio and high density of pigments and fillers in the formula. After the precipitated fire retardant coating is sprayed into the annular gap between the pipe and the sleeve, it will still affect the uniformity of the coating thickness, thereby affecting the fire retardant effect of the fire retardant coating on the annular gap between the pipe and the sleeve.

[0004] Therefore, in order to solve the problem that the fire retardant coating is precipitated and affects the fire retardant effect of the annular gap between the pipe and the sleeve, a fire retardant material filling device and a method of using the same are proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a fireproof material filling device and a method for using the same, which solves the problem that the fireproof coating precipitates and affects the fireproof effect of the annular gap between the pipe and the sleeve. The fireproof coating is automatically stirred while the nozzle rotates and sprays in a fixed trajectory, which effectively avoids the precipitation of the fireproof coating, ensures the uniformity of the coating, and further ensures the fireproof effect of the fireproof coating.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A fireproof material filling device, comprising a sleeve, a hollow column, a sleeve one, a sleeve two, a feed pipe, a delivery pipe, a discharge pipe and a nozzle, wherein the sleeve and the hollow column are sleeved at both ends of the sleeve one, the sleeve two is sleeved with the sleeve, one end of the sleeve two is sleeved with the sleeve (here the sleeve is fixedly sleeved with the sleeve one, the hollow column and the sleeve one as well as the sleeve and the sleeve two are sleeved with a sealing bearing), the other end of the sleeve two is connected with the hollow column, one end of the feed pipe is penetrated through one side of the hollow column, the two ends of the delivery pipe are respectively plugged with the hollow column and the sleeve two, one end of the discharge pipe is plugged with the sleeve The other end of the discharge pipe is connected to the nozzle, and also includes an arc-shaped clamping plate, a mounting frame, a locking mechanism, a stirring blade, a motor and a stirring filling mechanism. The arc-shaped clamping plates are provided in three and are circumferentially arranged outside the pipeline. The mounting frame is arranged on the hollow column. The locking mechanism is arranged on the mounting frame. When the sleeve is installed, the locking mechanism drives the arc-shaped clamping plate to approach the pipeline. There are multiple stirring blades arranged around the outer wall of the sleeve. The motor is arranged on the mounting frame. When the motor is working, the stirring filling mechanism drives the nozzle to rotate in a uniform circle and drives the stirring blade to rotate inside the hollow column.

[0008] By adopting the above scheme, the nozzle can be ensured to rotate at a constant speed along a fixed trajectory during the spraying process, and manual spraying by the staff is not required. At the same time, the entanglement of the feed pipe, the delivery pipe, and the discharge pipe with the pipeline can be avoided. The fire retardant coating can also be sprayed evenly in the annular gap between the pipeline and the sleeve, and the fire retardant coating can be automatically stirred during the spraying process without stirring in advance. At the same time, in the spraying interval, there is no need to consider the precipitation of the fire retardant coating due to standing, so that the thickness of the fire retardant coating in the annular gap between the pipeline and the sleeve is uniform, which effectively ensures the fire prevention effect.

[0009] Preferably, the locking mechanism includes a worm, a worm wheel, a triangular block, a fixed plate, a connecting rod, a spring, a fixed block one and a fixed block two, the worm being inserted into the mounting frame, the worm wheel being sleeved with a hollow column and meshingly arranged below the worm, the triangular block being arranged on the side wall of the worm wheel, the fixed plate being arranged on the side wall of the hollow column, the connecting rod and the spring being movably inserted into the interior of the fixed plate, one end of the connecting rod being arranged as an arc end face and contacting with the inclined surface of the triangular block, the other end of the connecting rod being connected to an arc-shaped clamping plate, the connecting rod being sleeved with the spring, the fixed block one and the fixed block two being arranged at two ends of the spring, the fixed block one being arranged above the fixed block two and movably sleeved with the connecting rod, the fixed block two being fixedly sleeved with the connecting rod, and a knocking mechanism being arranged on the side wall of the sleeve one, and the knocking mechanism intermittently drives the fixed block one to move upward when the sleeve one rotates.

[0010] By adopting the above scheme, the hollow column and the pipe can be sleeved together, and the axis of the hollow column and the axis of the pipe can be ensured to coincide. During the rotation of the sleeve, the cooperation of the knocking mechanism and the spring can be utilized to achieve continuous knocking on the hollow column. In the process of deformation of the spring, the clamping effect of the three arc-shaped clamping plates on the pipe will not be affected, thereby effectively ensuring the stability of the installation of the hollow column, and then ensuring that the nozzle can rotate along a fixed trajectory, thereby improving work efficiency and effectively ensuring the uniformity of the fire retardant coating spraying thickness.

[0011] Preferably, the knocking mechanism includes a driving rod and an L-shaped plate, wherein the L-shaped plate is movably arranged inside the fixed plate and connected to the bottom of the fixed block 1, the fixed end of the driving rod is connected to the side wall of the sleeve 1, and the free end of the driving rod is provided with a wedge-shaped end surface.

[0012] It can be seen that since the coating at the bubble is thin, it cannot provide uniform fire protection, and at the same time it will cause the strength and durability of the coating to decrease, and there are gaps in the coating at the bubble, and it is impossible to form a uniform protective layer, thus affecting the fireproof effect of the fire retardant coating. In the raw material barrel containing the fire retardant coating, when the liquid level of the fire retardant coating is lower than the input end of the pump, air will enter the interior of the hollow column, resulting in bubbles in the fire retardant coating sprayed from the nozzle, thus affecting the fireproof effect of the coating, so this solution is adopted. It is possible to continuously knock the hollow column during the spraying of the fire retardant coating, so that the bubbles generated by the stirring blades inside the hollow column during the stirring process can float upward quickly due to the vibration caused by the continuous knocking of the hollow column, thereby preventing the bubbles from being sprayed from the nozzle into the annular gap between the pipe and the sleeve, and then effectively ensuring the uniformity of the coating, that is, effectively ensuring the fireproof effect of the fire retardant coating.

[0013] Preferably, the stirring filling mechanism includes a mounting plate, a gear and a gear ring, the mounting plate is arranged on the mounting frame, the motor is arranged on the mounting plate, the output end of the motor is connected to the gear, the gear ring is sleeved with the sleeve, the gear is meshed with the gear ring, and a plurality of stirring rods are arranged in an internal circumferential array of the sleeve.

[0014] It can be seen that the fire retardant coating is contained in the raw material barrel, and a small amount of raw materials are precipitated before use. In the process of extracting the fire retardant coating, the pump can use its own power to achieve preliminary stirring of the fire retardant coating, but it cannot completely avoid the precipitation of the fire retardant coating, so this solution is adopted. During the rotation of the sleeve, the stirring blades and the stirring rod are driven to rotate synchronously, and the fire retardant coating entering the hollow column, sleeve and sleeve 2 is automatically stirred, thereby saving working time and eliminating the need to stir the fire retardant coating before use. And when spraying again after stopping spraying for a long time, the influence caused by the precipitation of the fire retardant coating can also be avoided, effectively ensuring the fire retardant effect of the fire retardant coating.

[0015] Preferably, the stirring rod includes stirring roller 1 and stirring roller 2, and the stirring roller 1 and stirring roller 2 are both arranged inside the sleeve, and the interiors of the stirring roller 1 and stirring roller 2 are both sleeved with rotating rods, and the ends of the rotating rods are connected to the inner wall of the sleeve. The surfaces of the stirring roller 1 and stirring roller 2 are respectively provided with spiral stirring groove 1 and spiral stirring groove 2, the surface of the stirring roller 1 is in contact with the outer wall of the sleeve 1, and the surface of the stirring roller 2 is in contact with the inner wall of the sleeve 2.

[0016] By adopting the above scheme, in the process of the sleeve driving the sleeve one to rotate, multiple stirring rollers one and two can be driven to rotate around the sleeve one, and under the action of the friction between the stirring roller one and the sleeve one and between the stirring roller two and the sleeve two, the stirring roller one and the stirring roller two can rotate autonomously, and at the same time, the spiral stirring grooves one and two opened on their respective surfaces can be used to improve the stirring effect. On the one hand, it can prevent the precipitate of the fire-retardant coating from clogging the nozzle, and on the other hand, it can prevent the precipitate from affecting the fire-retardant effect.

[0017] Preferably, the surface of the stirring roller 1 contacts the surface of the stirring roller 2, and the spiral stirring tank 1 and the spiral stirring tank 2 are in the same direction.

[0018] By adopting the above scheme, since the stirring roller one and the stirring roller two rotate in opposite directions, but the outer diameter of the sleeve one and the inner diameter of the sleeve two are different, the stirring roller one and the stirring roller two can rotate at different speeds during the revolution, so that the fire retardant coating between the stirring roller one and the stirring roller two can be ground during the rotation of the stirring roller one and the stirring roller two, and the stirring roller one and the stirring roller two can stir the fire retardant coating in different directions through the spiral stirring tank one and the spiral stirring tank two respectively during the rotation, so as to effectively avoid the precipitation of the fire retardant coating and affect the subsequent fire prevention effect.

[0019] Preferably, a plurality of stirring holes are provided inside the stirring blade, each of the stirring holes is a conical hole, and a spiral guide groove is provided on the inner wall of each of the stirring holes.

[0020] By adopting the above scheme, the fire-retardant coating inside the hollow column can pass through the stirring hole and rotate under the action of the spiral guide groove as the stirring blade follows the rotation of the sleeve, thereby further improving the stirring effect of the fire-retardant coating entering the hollow column and further avoiding the problem of the fire-retardant coating settling and affecting the filling effect.

[0021] A method for using a fireproof material filling device comprises the following steps:

[0022] S1. After fixing the position of the pipeline, the entire packing device is connected to the pipeline, and the worm is rotated to drive the three arc-shaped clamping plates to clamp on the outer wall of the pipeline through the locking mechanism to fix the position of the entire packing device;

[0023] S2. Start the motor, the output end of the motor drives the sleeve to rotate through the meshing of the gear and the gear ring, and the nozzle is driven to rotate at a fixed speed through the discharge pipe during the rotation of the sleeve. When the sleeve rotates, the stirring blades and stirring rods are driven to stir the fire retardant coating inside the sleeve, the hollow column and the second sleeve;

[0024] S3. During the rotation of the sleeve 1, the plurality of driving rods are driven to continuously squeeze the corresponding fixed block 1, and the fixed block 1 strikes the fixed plate during the process of resetting after being separated from the corresponding fixed plate.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Through the motor and stirring filler mechanism, the sleeve and the discharge pipe can be driven to drive the nozzle to rotate at a fixed speed in a fixed trajectory during the operation of the motor, and the fire retardant coating sprayed from the nozzle can be evenly coated in the annular gap between the pipe and the sleeve, and the thickness of the coating layer at different positions can be guaranteed to be the same after spraying. In the process of sleeve rotation, the fixed sleeve connection between the sleeve and the sleeve one can be used to drive the sleeve one to drive the stirring blade to rotate, and at the same time, the stirring rod set inside the sleeve can be used to achieve double stirring of the fire retardant coating, effectively avoiding the appearance of sediment in the fire retardant coating, and thus ensuring the fire retardant effect of the coating after the fire retardant coating is sprayed.

[0027] 2. By setting the stirring roller one and the stirring roller two, in the process of following the sleeve to revolve around the sleeve one, the stirring roller one and the stirring roller two can utilize the friction between the outer wall of the sleeve one and the inner wall of the sleeve two to rotate, so that the fire retardant coating can be stirred by the spiral stirring tank one and the spiral stirring tank two respectively, further avoiding the precipitation of the fire retardant coating, and at the same time, through the contact between the stirring roller one and the stirring roller two, and the different rotation speeds of the stirring roller one and the stirring roller two, the fire retardant coating can be ground, further ensuring the uniformity of the fire retardant coating, that is, ensuring the uniform thickness of the coating after the fire retardant coating is sprayed out, and thus effectively ensuring the fire retardant effect of the fire retardant coating.

[0028] 3. Through the set knocking mechanism, the hollow column can be continuously knocked when the fire-retardant coating is stirred. The vibration generated during the knocking process can accelerate the floating speed of the bubbles generated when the fire-retardant coating is stirred, thereby preventing the bubbles from being sprayed from the nozzle into the annular gap between the pipe and the sleeve, eliminating the influence of the bubbles generated when the feed pump extracts the fire-retardant coating from the raw material barrel on the coating thickness, further ensuring the uniformity of the coating thickness, thereby ensuring the fire-retardant effect of the fire-retardant coating on the annular gap between the pipe and the sleeve.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 9 The present invention provides a fireproof material filling device and a method for using the same, and the technical solution is as follows:

[0041] For details, please refer to Figure 1 and Figure 2A fireproof material filling device includes a sleeve 1, a hollow column 2, a sleeve 1 3, a sleeve 2 4, a feed pipe 5, a conveying pipe 6, a discharge pipe 7 and a nozzle 8. The sleeve 1 and the hollow column 2 are sleeved at both ends of the sleeve 1 3, the sleeve 2 4 is sleeved with the sleeve 1 3, one end of the sleeve 2 4 is sleeved with the sleeve 1, and the other end of the sleeve 2 4 is connected with the hollow column 2. It also includes an arc-shaped card plate 9, a mounting frame 10, a locking mechanism 11, a stirring blade 12, a motor 13 and a stirring filling mechanism 14. The arc-shaped card plate 9 is provided with Three arc-shaped clamping plates 9 are circumferentially arranged outside the pipe c, and are arranged at equal intervals. Under the clamping action of the three arc-shaped clamping plates 9 and the pipe c, the positions of the sleeve 1, the hollow column 2, the sleeve one 3 and the sleeve two 4 can be fixed, so that the moving trajectory of the nozzle 8 can be fixed. Since the feed pipe 5, the delivery pipe 6 and the discharge pipe 7 are independently arranged, the feed pipe 5, the delivery pipe 6 and the discharge pipe 7 will not be entangled with the pipe c during the rotation of the nozzle 8.

[0042] As an embodiment of the present invention, refer to Figure 3 The mounting frame 10 is arranged on the hollow column 2, and the locking mechanism 11 is arranged on the mounting frame 10. When the sleeve 13 is installed, the locking mechanism 11 drives the arc clamping plate 9 to approach the pipe c. The locking mechanism 11 includes a worm 111, a worm wheel 112, a triangular block 113, a fixing plate 114, a connecting rod 115, a spring 116, a fixing block 117 and a fixing block 2 118. The worm 111 is penetrated on the mounting frame 10, and the worm wheel 112 is sleeved and meshed with the hollow column 2 and is arranged below the worm 111. The triangular block 113 is arranged on the side wall of the worm wheel 112, and the fixing plate 1 14 is arranged on the side wall of the hollow column 2, the connecting rod 115 and the spring 116 are both movably arranged inside the fixing plate 114, one end of the connecting rod 115 is arranged as an arc end face and contacts with the inclined surface of the triangular block 113, the other end of the connecting rod 115 is connected to the arc clamping plate 9, the connecting rod 115 is sleeved with the spring 116, the fixing block 117 and the fixing block 2 118 are arranged at both ends of the spring 116, the fixing block 117 is arranged above the fixing block 2 118 and is movably sleeved with the connecting rod 115, and the fixing block 2 118 is fixedly sleeved with the connecting rod 115.

[0043] During installation, first fix the sleeve b in the through hole inside the wall a, then coaxially pass the pipe c inside the sleeve b and fix it, after the sleeve 3 is sleeved with the pipe c, rotate the worm 111, and the worm 111 is driven to rotate by meshing with the worm wheel 112 during the rotation of the worm 111. Since the side wall of the worm wheel 112 is provided with a triangular block 113, and the inclined surface of the triangular block 113 is in contact with the arc end surface of the connecting rod 115, the triangular block 113 is rotated as the worm wheel 112 rotates. During the rotation of the worm gear 112, the inclined surface of the triangular block 113 will squeeze the connecting rod 115. After being squeezed, the arc end face of the connecting rod 115 will drive the arc clamping plate 9 to approach the outer wall of the pipe c. Therefore, under the joint action of the three triangular blocks 113 and the three arc clamping plates 9, the position of the sleeve 1, the hollow column 2, the sleeve one 3 and the sleeve two 4 can be fixed, and the sleeve 1, the hollow column 2, the sleeve one 3 and the sleeve two 4 can be coaxially connected with the pipe c.

[0044] As an embodiment of the present invention, refer to Figure 3 , Figure 4 Figure 5 and Figure 6 A knocking mechanism 15 is provided on the side wall of the sleeve 3. When the sleeve 3 rotates, the knocking mechanism 15 intermittently drives the fixed block 117 to move upward. The knocking mechanism 15 includes a driving rod 151 and an L-shaped plate 152. The L-shaped plate 152 is movably arranged inside the fixed plate 114 and connected to the bottom of the fixed block 117. The fixed end of the driving rod 151 is connected to the side wall of the sleeve 3, and the free end of the driving rod 151 is provided with a wedge-shaped end surface.

[0045] Since the fixed end of the driving rod 151 is connected to the end of the sleeve 13, the driving rod 151 can be driven to rotate together during the rotation of the sleeve 13, and the free end of the driving rod 151 is provided with a wedge-shaped end surface. During the rotation of the driving rod 151, the wedge-shaped end surface provided at the free end of the driving rod 151 can squeeze the corresponding L-shaped plate 152. After being squeezed, the L-shaped plate 152 drives the fixing block 117 to separate from the fixing plate 114. Since the two ends of the spring 116 are respectively connected to the fixing block 117 and the fixing block 2 118, and the fixing block 2 118 is fixedly sleeved with the connecting rod 115, the arc-shaped clamping plate 9 will be stretched through the connecting rod 115 and the fixing block 2 118 during the clamping of the pipe c. Spring 116, and the fixing block 117 can further stretch the spring 116 during the separation process from the fixing plate 114. When the driving rod 151 continues to rotate, until the free end of the driving rod 151 is separated from the L-shaped plate 152, the spring 116 can pull the fixing block 117 through its own elastic force, so that the fixing block 117 can fit with the fixing plate 114 again, and the fixing block 117 can collide with the fixing plate 114 during the process of fitting again, which has a vibrating effect on the hollow column 2, and then the bubbles inside the hollow column 2 can float up quickly, avoiding the situation where bubbles are sprayed from the nozzle 8 into the annular gap, thereby ensuring the uniformity of the fire retardant coating spraying, that is, ensuring the fire retardant effect of the fire retardant coating.

[0046] As an embodiment of the present invention, refer to Figure 2 , Figure 7 and Figure 8 A plurality of stirring blades 12 are arranged around the outer wall of the sleeve 3, and the motor 13 is arranged on the mounting frame 10. When the motor 13 is working, the stirring filling mechanism 14 drives the nozzle 8 to rotate in a uniform circular motion and drives the stirring blades 12 to rotate inside the hollow column 2. The stirring filling mechanism 14 includes a mounting plate 141, a gear 142 and a gear ring 143. The mounting plate 141 is arranged on the mounting frame 10, and the motor 13 is arranged on the mounting plate 141. The output end of the motor 13 is connected to the gear 142, the gear ring 143 is sleeved with the sleeve 1, and the gear 142 is meshed with the gear ring 143. A plurality of stirring rods 144 are arranged in an inner circumferential array of the sleeve 1.

[0047] Since the gear 142 is arranged at the output end of the motor 13 and meshes with the gear ring 143, when the motor 13 is working, the gear 142 can be driven to drive the gear ring 143 to rotate, and the gear ring 143 is fixedly sleeved with the sleeve 1, and the stirring rod 144 is arranged inside the sleeve 1 and connected to the sleeve 1, so the gear ring 143 can directly drive the stirring rod 144 to rotate during the rotation process, and the sleeve 1 can drive the sleeve 3 to rotate through the fixed sleeve connection with the sleeve 3 during the rotation process. Since the stirring blade 12 is arranged on the tube wall of the sleeve 3, the sleeve 3 can drive the stirring blade 12 to rotate during the rotation process. Through the dual effects of the stirring rod 144 and the stirring blade 12, the fire retardant coating can be effectively stirred, thereby effectively avoiding the precipitation of the fire retardant coating, and further effectively ensuring the fire retardant effect of the fire retardant coating.

[0048] As an embodiment of the present invention, refer to Figure 8 and Fig. 9 The stirring rod 144 includes a stirring roller 1441 and a stirring roller 1442. The stirring roller 1441 and the stirring roller 1442 are both arranged inside the sleeve 1. The stirring roller 1441 and the stirring roller 1442 are both sleeved with a rotating rod 1443. The end of the rotating rod 1443 is connected to the inner wall of the sleeve 1. The surfaces of the stirring roller 1441 and the stirring roller 1442 are respectively provided with a spiral stirring groove 14411 and a spiral stirring groove 2 14421. The surface of the stirring roller 1441 contacts the outer wall of the sleeve 3, and the surface of the stirring roller 1442 contacts the inner wall of the sleeve 4.

[0049] Since stirring roller 1 1441 and stirring roller 2 1442 are respectively connected to sleeve 1 through rotating rod 1443, stirring roller 1 1441 and stirring roller 2 1442 can be driven to rotate around sleeve 1 3 during the rotation of sleeve 1 to achieve preliminary stirring of the fire retardant coating. Since stirring roller 1 1441 is in contact with the outside of sleeve 3 and stirring roller 2 1442 is in contact with the inner wall of sleeve 2 4, stirring roller 1 1441 and stirring roller 2 1442 can respectively revolve around their own axes as rotation axes under the action of their respective friction forces during the revolution of stirring roller 1 1441 and stirring roller 2 1442 around sleeve 3, and at the same time cooperate with spiral stirring tank 1 14411 and spiral stirring tank 2 14421 to achieve re-stirring of the fire retardant coating, thereby further avoiding the precipitation of the fire retardant coating, that is, further ensuring the fire retardant effect of the fire retardant coating.

[0050] As an embodiment of the present invention, refer to Fig. 9 The surface of the stirring roller 1 1441 contacts the surface of the stirring roller 2 1442 , and the directions of the spiral stirring tank 1 14411 and the spiral stirring tank 2 14421 are the same.

[0051] Since the surfaces of stirring roller 1441 and stirring roller 2 1442 are in contact and the rotation directions of stirring roller 1441 and stirring roller 2 1442 are opposite, stirring roller 1441 and stirring roller 2 1442 can grind the fire retardant coating between them during their rotation. Since stirring roller 1441 and stirring roller 2 1442 have different rotation directions, the corresponding spiral stirring tank 1 14411 and spiral stirring tank 2 14421 can be used to drive the fire retardant coating to flow in different directions, thereby further realizing the stirring of the fire retardant coating, and further ensuring the fire retardant effect of the fire retardant coating.

[0052] As an embodiment of the present invention, refer to Figure 8 and 9 A plurality of stirring holes 121 are formed inside the stirring blade 12 . Each stirring hole 121 is a tapered hole. A spiral guide groove 122 is formed on the inner wall of each stirring hole 121 .

[0053] Instructions attached Figure 8 The rotation direction of the sleeve 1 is shown in the figure, and the end of the stirring hole 121 facing the rotation direction of the sleeve 1 has a large aperture. Since the stirring blade 12 rotates with the sleeve 3, after the fire retardant coating enters the interior of the hollow column 2 through the feeding pipe 5, the rotation of the stirring blade 12 can quickly gather the fire retardant coating. During the rotation of the stirring blade 12, when the fire retardant coating passes through the stirring hole 121, it will achieve an acceleration effect through the spiral guide groove 122, thereby accelerating the flow of the fire retardant coating inside the hollow column 2, thereby achieving rapid stirring of the fire retardant coating, and effectively avoiding the precipitation of the fire retardant coating.

[0054] A method for using a fireproof material filling device comprises the following steps:

[0055] S1. After fixing the position of pipe c, the entire packing device is sleeved with pipe c, and the worm 111 is rotated to drive the three arc-shaped card plates 9 to be clamped on the outer wall of pipe c through the locking mechanism 11 to fix the position of the entire packing device;

[0056] S2. Start the motor 13, the output end of the motor 13 drives the sleeve 1 to rotate through the meshing of the gear 142 and the gear ring 143, and the sleeve 1 rotates through the discharge pipe 7 to drive the nozzle 8 to rotate at a fixed speed at a fixed trajectory, and the sleeve 1 rotates to drive the stirring blade 12 and the stirring rod 144 to stir the fire retardant coating inside the sleeve 1, the hollow column 2 and the sleeve 4;

[0057] S3. During the rotation of the sleeve 3, the plurality of driving rods 151 are driven to continuously squeeze the corresponding fixed block 117, and the fixed block 117 is separated from the corresponding fixed plate 114 and knocks on the fixed plate 114 during the reset process.

[0058] Working principle: In order to fix the rotation trajectory of the nozzle 8, the locking mechanism 11 is set up, the self-locking function between the worm wheel 112 and the worm 111 is utilized, and the three arc-shaped clamping plates 9 are cooperated to coaxially fix the hollow column 2 on the pipe c; in order to realize the uniform rotation of the nozzle 8 and to evenly mix the fire-retardant coating before it is sprayed out from the nozzle 8, the stirring filling mechanism 14 is set up, which can drive the nozzle 8 to rotate at a uniform speed on the fixed trajectory, and in the process of rotation, the driving effect of the motor 13 can be used to drive the stirring rod 144 and the stirring blade 12 to rotate, so that the fire-retardant coating is evenly and automatically stirred after entering the interior of the hollow column 2, effectively preventing the fire-retardant coating from settling, thereby ensuring the fire-retardant effect of the fire-retardant coating; and in order to avoid the influence of bubbles generated during the stirring process, the knocking mechanism 15 is set up, and the hollow column 2 can be continuously knocked during the rotation of the sleeve 3, so that the bubbles in the fire-retardant coating can float up quickly, thereby preventing the bubbles from entering the interior of the nozzle 8 and being sprayed out from the nozzle 8.

[0059] Specific:

[0060] The sleeve 1, the hollow column 2, the sleeve 1 3, the sleeve 2 4 are sleeved with the pipe c, and the worm 111 is rotated. The worm 111 drives the worm wheel 112 to rotate during the rotation of the worm 111. The worm wheel 112 drives the triangular block 113 set on the side wall to rotate during the rotation of the triangular block 113. During the rotation of the triangular block 113, the connecting rod 115 is squeezed through its own inclined surface, so that the connecting rod 115 drives the arc clamping plate 9 to approach and finally clamp with the outer wall of the pipe c. The position of the entire device can be fixed by the self-locking function of the worm wheel 112 and the worm 111;

[0061] The motor 13 is started, and the output end of the motor 13 drives the gear 142 to rotate. During the rotation of the gear 142, the gear ring 143 is driven to rotate by meshing with the gear ring 143. During the rotation of the gear ring 143, the sleeve 1 is driven to rotate by sleeve engagement with the sleeve 1. Since the nozzle 8 is connected to the sleeve 1 through the discharge pipe 7, the movement trajectory of the nozzle 8 can be fixed;

[0062] During the rotation of the sleeve 1, the stirring rod 144 is driven to rotate by connecting with the stirring rod 144. Since the sleeve 1 is fixedly sleeved with the sleeve 13, and the tube wall of the sleeve 13 is provided with a stirring blade 12, the stirring rod 144 and the stirring blade 12 can rotate synchronously, thereby achieving a preliminary stirring treatment of the fire retardant coating.

[0063] During the rotation of the sleeve 1, through the friction between the stirring roller 1441 and the sleeve 1 3 and between the stirring roller 2 1442 and the sleeve 2 4, the stirring roller 1441 and the stirring roller 2 1442 can achieve a self-rotation effect during the revolution around the sleeve 1 3, and the self-rotation directions of the stirring roller 1441 and the stirring roller 2 1442 are opposite, so that the fire retardant coating can be further stirred through the spiral stirring tank 1 14411 and the spiral stirring tank 2 14421 respectively, and the contact between the stirring roller 1 1441 and the stirring roller 2 1442 can grind the fire retardant coating between the stirring roller 1 1441 and the stirring roller 2 1442 during the reverse rotation of the stirring roller 1 1441 and the stirring roller 2 1442, thereby further avoiding the precipitation of the fire retardant coating;

[0064] During the rotation of the sleeve 3, the driving rod 151 arranged at the end of the sleeve 3 can rotate with the sleeve 3, and the wedge-shaped end face arranged at the free end of the driving rod 151 can squeeze the corresponding L-shaped plate 152, so that the L-shaped plate 152 drives the fixed block 117 to separate from the corresponding fixed plate 114, and the spring 116 can be stretched during the separation of the fixed block 117 from the fixed plate 114. After the driving rod 151 and the L-shaped plate 152 are misaligned, the spring 116 is reset by its own elastic force, thereby being able to drive the fixed block 117 to collide with the fixed plate 114. The vibration generated during the collision can make the bubbles generated during the stirring of the fire retardant coating quickly float up, thereby preventing the bubbles from following the fire retardant coating and being sprayed out from the nozzle 8 to affect the fire retardant effect of the fire retardant coating.
