Description

Technical Field

[0001] This utility model belongs to the technical field of material conveying devices, and specifically relates to a material conveying device for fireproof coatings. Background Technology

[0002] Fire-retardant coatings are a type of passive fire-retardant material with special functions. They not only provide decorative and anti-corrosion protection, but more importantly, they can actively delay the spread of fire and protect building structures or equipment in the event of a fire, thus buying valuable time for personnel evacuation and fire rescue. The transportation of fire-retardant coatings is an indispensable key link in their production, storage and construction process. This is not just a simple "handling", but a systematic requirement to achieve efficient, safe and high-quality operations.

[0003] Most existing material conveying devices transport paint through conveying pipes. One end of the conveying pipe is equipped with a storage hopper for storing paint, and the other end is equipped with a conveying device for discharging paint. Although this can meet the needs of conveying paint, in this method, the paint to be conveyed is placed inside the storage hopper for a long time. The paint may clump due to the long storage time. The clumps of paint cannot be broken up in time. The clumps are usually hard and can easily cause abrasion or impact on the conveying pipe, increasing equipment wear, shortening service life, and increasing production costs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a conveying device for fire-retardant coatings. Through the continuous up-and-down reciprocating motion of the set dispersing plate inside the storage hopper, the hardened lumps can be completely broken up, restoring fluidity, preventing pipe blockage or pumping failure caused by lumps, and improving conveying efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a conveying device for fireproof coating, including a base plate, a conveying cylinder is provided on the upper end of the base plate through a support column, a discharge pipe is provided on the lower right side of the conveying cylinder, an inlet is provided on the upper left side of the conveying cylinder, a storage hopper is connected to the inlet, a symmetrically arranged feeding hopper is provided on the upper end of the storage hopper, a rotating column is rotatably arranged inside the storage hopper, a sleeve is slidably fitted on the outer side of the rotating column, a uniformly distributed dispersing disc is fixedly fitted on the outer arc surface of the sleeve, and a uniformly distributed perforation is provided on the upper surface of the dispersing disc, and a driving unit is provided on the upper end of the storage hopper for driving the sleeve to slide along the rotating column.

[0006] As a further improvement of this utility model, the drive unit includes a mounting frame set at the upper end of the storage hopper. A slider is symmetrically slidably arranged inside the mounting frame. A rotating seat is symmetrically arranged at the upper end of the sleeve. A rotating plate is rotatably arranged between the slider and the adjacent rotating seat. A drive component for driving the slider to move is set inside the mounting frame. The drive component includes a telescopic push rod set on the side wall of the mounting frame. The telescopic ends of the telescopic push rods are connected to the slider. A synchronous controller is set on the two telescopic push rods.

[0007] As a further improvement of this utility model, the driving component includes a telescopic push rod disposed on the side wall of the mounting bracket. The telescopic ends of the telescopic push rods are all connected to the sliding joint, and a synchronization controller is disposed on the two telescopic push rods.

[0008] As a further improvement of this utility model, the scraper abuts against the inner wall of the storage hopper.

[0009] As a further improvement of this utility model, a spiral conveying roller is rotatably arranged inside the conveying cylinder, and a second motor is arranged on the right end face of the conveying cylinder, with the output end of the second motor connected to the spiral conveying roller.

[0010] As a further improvement of this utility model, a number of casters are evenly arranged at the lower end of the base plate, and each caster is equipped with a brake pad.

[0011] As a further improvement of this utility model, a control panel is provided on the front side of the base plate, and motor one, motor two and telescopic push rod are all electrically connected to the control panel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by setting up a dispersing plate, the slider moves and drives the rotating plate to rotate. The rotation of the rotating plate can drive the sleeve to slide up and down along the rotating column, which in turn drives the dispersing disc to move up and down. Fireproof coatings contain a large amount of inorganic fillers (such as expanded graphite and aluminum hydroxide). If left to stand for a long time, they are very easy to settle, compact, and form hard lumps at the bottom of the storage hopper. The dispersing disc moves up and down continuously under the drive of the transmission mechanism, which can completely break up the hardened lumps, restore fluidity, prevent pipeline blockage or pumping failure caused by lumps, and improve conveying efficiency.

[0013] Secondly, by setting up a scraper, the rotating column drives the fixed plate to rotate, which in turn drives the scraper to rotate. The fire-retardant coating has a high viscosity and easily adheres to the inner wall, bottom and corners of the storage hopper or conveying chamber, forming a thick residual layer. The rotating scraper closely follows the inner wall of the storage hopper, which can continuously scrape off the coating adhering to the wall surface and push it back into the mainstream material, so as to maximize the recovery of raw materials, reduce waste and improve the utilization rate of single batch of materials.

[0014] Thirdly, by installing casters, the equipment can be pushed away from the work area and moved to a dedicated cleaning or maintenance area when the bottom and corners of the equipment need to be cleaned or inspected regularly. This makes it convenient to thoroughly clean or inspect hard-to-reach areas such as the bottom of the equipment and pipe interfaces, avoiding maintenance in critical areas of the production line and reducing interference with normal production.

[0015] Fourth, by installing brake pads, if the equipment is continuously subjected to external forces (such as pipeline pressure) during operation, these forces will be transmitted to the bearings and brackets of the casters. After the brake pads are locked, the weight of the equipment and external forces are mainly borne by the braking mechanism and the ground, rather than the wheel bearings, reducing abnormal wear and fatigue damage to the wheel bearings and extending the service life of the casters and the overall equipment.

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2As shown in Figure 3, a conveying device for fire-retardant coating includes a base plate 101. A conveying cylinder 102 is provided on the upper end of the base plate 101 via a support column. A discharge pipe 103 is provided on the lower right side of the conveying cylinder 102. An inlet is provided on the upper left side of the conveying cylinder 102, and a storage hopper 104 is connected to the inlet. A symmetrically arranged feeding hopper is provided on the upper end of the storage hopper 104. A rotating column 105 is rotatably arranged inside the storage hopper 104. A sleeve 106 is slidably sleeved on the outer side of the rotating column 105. A uniformly distributed dispersing disc 107 is fixedly sleeved on the outer arc surface of the sleeve 106. The upper surface of the dispersing disc 107 is provided with uniformly distributed perforations. A driving unit is provided on the upper end of the storage hopper 104 for driving the sleeve 106 to slide along the rotating column 105.

[0021] like Figure 2 , 3 As shown, the drive unit includes a mounting frame 201 mounted on the upper end of the storage hopper 104. A slider 202 is symmetrically slidably mounted inside the mounting frame 201. Rotating seats 203 are symmetrically mounted on the upper end of the sleeve 106. Rotating plates 204 are rotatably mounted between the slider 202 and the adjacent rotating seats 203. A drive component for moving the slider 202 is mounted inside the mounting frame 201. The drive component includes telescopic push rods 205 mounted on the side wall of the mounting frame 201. The telescopic ends of the telescopic push rods 205 are connected to the slider. A synchronization controller is mounted on each of the two telescopic push rods 205. Activating the synchronization controller controls... The telescopic push rod 205 synchronously pushes the slider 202 to slide relative to the mounting frame 201. The movement of the slider 202 drives the rotating plate 204 to rotate. The rotation of the rotating plate 204 can drive the sleeve 106 to slide up and down along the rotating column 105, thereby driving the dispersing disc 107 to move up and down. The fireproof coating contains a large amount of inorganic fillers (such as expanded graphite and aluminum hydroxide). After a long period of standing, it is easy to settle, compact, and form hard lumps at the bottom of the storage hopper 104. The dispersing disc 107 continuously moves up and down under the drive of the transmission mechanism, which can completely break up the hardened lumps, restore fluidity, prevent pipeline blockage or pumping failure caused by lumps, and improve conveying efficiency.

[0022] like Figure 2 , 3As shown, a motor 206 is installed at the upper end of the storage hopper 104. The output end of the motor 206 is connected to the rotating column 105 via a coupling. A fixing plate 207 is installed at the lower end of the rotating column 105. A scraper 208 is installed at the end of the fixing plate 207 away from the rotating column 105. The scraper 208 abuts against the inner wall of the storage hopper 104. When the motor 206 is started, the output end of the motor 206 can drive the rotating column 105 to rotate. The rotation of the rotating column 105 drives the fixing plate 207 to rotate, which in turn drives the scraper 208 to rotate. The fireproof coating has a high viscosity and easily adheres to the inner wall, bottom and corners of the storage hopper 104 or the conveying chamber, forming a thick residual layer. The rotating scraper 208 rotates closely against the inner wall of the storage hopper 104, which can continuously scrape off the coating adhering to the wall surface and push it back into the mainstream material, so as to maximize the recovery of raw materials, reduce waste and improve the utilization rate of single batch of materials.

[0023] like Figure 1 , 4 As shown, a spiral conveying roller 301 is rotatably installed inside the conveying cylinder 102. A second motor 302 is installed on the right end face of the conveying cylinder 102. The output end of the second motor 302 is connected to the spiral conveying roller 301. When the second motor 302 is started, the output end of the second motor 302 drives the spiral conveying roller 301 to rotate. When the spiral conveying roller 301 rotates, the "screw groove" formed by its pitch is like a series of continuous sealed cavities, pushing the material from the inlet to the outlet, providing a strong and stable thrust, easily overcoming the flow resistance caused by high viscosity, and thus realizing continuous and pulsation-free conveying, ensuring stable flow.

[0024] like Figure 1 As shown, several casters 303 are evenly arranged at the lower end of the base plate 101. The casters 303 can easily move the equipment from the warehouse to the production line or between different workstations, so as to quickly respond to production plan adjustments and shorten the changeover time.

[0025] like Figure 1 As shown, a control panel 305 is provided on the front side of the base plate 101. Motor 1 206, Motor 2 302 and telescopic push rod 205 are all electrically connected to the control panel 305. All control buttons, switches and displays are concentrated on one panel, so that operators can complete all operations in one position. It is clear at a glance, reduces misoperation, and eliminates the need to walk back and forth in different parts of the equipment, thus reducing labor intensity.

[0026] In use, the material to be conveyed is fed into the storage hopper 104 through the feed hopper. Then, motor 206 is started. The output of motor 206 drives the rotating column 105 to rotate. The rotation of the rotating column 105 drives the fixed plate 207 to rotate, which in turn drives the scraper 208 to rotate. The fire-retardant coating has a high viscosity and easily adheres to the inner wall, bottom, and corners of the storage hopper 104 or the conveying chamber, forming a thick residue layer. The rotating scraper 208 rotates closely against the inner wall of the storage hopper 104, continuously scraping off the coating adhering to the wall surface and pushing it back into the mainstream material, so as to maximize the recovery of raw materials, reduce waste, and improve the utilization rate of a single batch of material. Then, through synchronous... The controller activates the synchronous controller, which controls the telescopic push rod 205 to synchronously push the slider 202 to slide relative to the mounting frame 201. The movement of the slider 202 drives the rotating plate 204 to rotate. The rotation of the rotating plate 204 can drive the sleeve 106 to slide up and down along the rotating column 105, thereby driving the dispersing disc 107 to move up and down. The fireproof coating contains a large amount of inorganic fillers (such as expanded graphite and aluminum hydroxide). After a long period of standing, it is very easy to settle, compact, and form hard lumps at the bottom of the storage hopper 104. The dispersing disc 107 continuously moves up and down under the drive of the transmission mechanism, which can completely break up the hardened lumps, restore fluidity, prevent pipeline blockage or pumping failure caused by lumps, and improve conveying efficiency.

[0027] After the material is broken up by the dispersing plate, it falls into the inside of the conveying cylinder 102. Then, the second motor 302 is started. The output end of the second motor 302 drives the spiral conveying roller 301 to rotate. When the spiral conveying roller 301 rotates, the "screw groove" formed by its pitch is like a series of continuous sealed cavities, pushing the material from the inlet to the outlet, providing a strong and stable thrust, easily overcoming the flow resistance caused by high viscosity, thereby achieving continuous and pulsation-free conveying, ensuring stable flow, and then allowing the material to be discharged through the discharge pipe 103.

[0028] According to another embodiment of the present invention, such as Figure 1 As shown, each caster wheel 303 is equipped with a brake pad 304. If the equipment is subjected to external forces (such as pipeline pressure) during operation, these forces will be transmitted to the bearings and brackets of the caster wheel 303. After the brake pad 304 is locked, the weight of the equipment and the external forces are mainly borne by the braking mechanism and the ground, rather than the wheel bearings, which reduces abnormal wear and fatigue damage to the wheel bearings and extends the service life of the caster wheel 303 and the overall equipment.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
