Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane processing technology, and in particular to a waterproof membrane bitumen extrusion device. Background Technology

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up. According to their main waterproof components, they can be divided into three categories: asphalt waterproof materials, polymer-modified waterproof membranes, and synthetic polymer waterproof membranes. Asphalt waterproof membranes are rolled up sheet waterproof materials made by impregnating asphalt on a base material (such as paper or fiber fabric) and then sprinkling powdered or sheet-like isolation material on the surface. The required asphalt thickness varies in different types and uses of waterproof membranes.

[0003] The patent database discloses a waterproof membrane bitumen extrusion device (application number: 202420980253.9). The technical solution is to transport bitumen to the discharge port by the propelling blade, and then discharge it through the extrusion head. Finally, the cleaning component is used to remove the bitumen adhering to the inner wall of the device.

[0004] However, after the asphalt is extruded, the required thickness of the asphalt varies depending on the type and application of the waterproof membrane. This requires changing the extrusion head to a different size, which is cumbersome and requires the equipment to be shut down, affecting work efficiency.

[0005] Therefore, it is necessary to invent a waterproof membrane bitumen extrusion device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a waterproof membrane asphalt extrusion device. When it is necessary to adjust the asphalt coating thickness on the waterproof membrane, the base tube is moved from the stop block to the rectangular groove by traction. Then, the limit cover is removed and the knob is rotated, causing the rotating rod to drive the gear to rotate, thereby causing the rack to move the scraper up and down, so that the height of the base tube at the bottom of the scraper in the rectangular groove is consistent with the required asphalt thickness. Then, the upper limit cover is installed, and then the asphalt can be fed into the base tube in the storage bin through the discharge chute and discharge port. The base tube moves by traction, which allows the scraper to evenly coat the asphalt on the base tube. This allows the asphalt to be directly and evenly coated on the base tube after processing and extrusion. At the same time, it can control the asphalt thickness required for different types and uses of waterproof membranes without changing parts. This solves the problem mentioned in the background art that after asphalt extrusion, different sizes of extrusion heads need to be changed because the required asphalt thickness of waterproof membranes varies for different types and uses. This makes the operation cumbersome and requires the equipment to be stopped during the process, which affects work efficiency.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a waterproof membrane bitumen extrusion apparatus, comprising:

[0033] like Figures 1-6 As shown, the waterproof membrane bitumen extrusion apparatus disclosed herein may include components such as a feeding assembly 100 and an extrusion assembly 110.

[0034] like Figure 1-6 As shown, this disclosure includes:

[0035] Feeding assembly 100, the feeding assembly 100 includes housing 101;

[0036] Extrusion assembly 110 includes a storage bin 111. The top of the storage bin 111 is fixedly connected to the bottom of the outer shell 101. A discharge port 112 is provided at the top of the storage bin 111. A rectangular groove 113 is provided at the front end of the storage bin 111. A stop block 114 is fixedly installed on the inner wall of the bottom of the rear end of the storage bin 111. A fixing plate 115 is provided at the top of the rectangular groove 113. The top of the fixing plate 115 is fixedly connected to the storage bin 111. A sliding groove 116 is provided at the bottom of the fixing plate 115. The inner wall of the trough 116 is provided with a scraper 117. A rack 118 is fixedly installed on the top of the scraper 117. The rack 118 meshes with a gear 119. A rotating rod 120 is sleeved and fixed to the gear 119. One end of the rotating rod 120 is inserted into the storage bin 111. A knob 121 is fixedly installed on the outer wall of the end of the rotating rod 120 that is inserted into the storage bin 111. A limit cover 122 is inserted into the outer wall of the knob 121. Limit blocks 123 are fixedly installed at both ends of the limit cover 122. A limit opening is provided on one side of the storage bin 111. The limiting block 123 is slidably connected to the limiting groove 124. The storage hopper 111 supports the outer shell 101, and asphalt inside the outer shell 101 can enter the storage hopper 111 through the discharge chute 107 and discharge port 112. A stop block 114 fixed at the rear end of the storage hopper 111 prevents asphalt from flowing out. The scraper 117 and rack 118 can move up and down within the slide groove 116. The rotating rod 120 can be rotated by turning the knob 121, thereby rotating the gear 119. The rack 118 and scraper 117 are moved up and down, thereby adjusting the distance between the bottom of scraper 117 and storage bin 111 to the required asphalt thickness for the waterproof membrane. The limiting cover 122 has a groove inside, which can lock the knob 121. The limiting blocks 123 fixed on both sides of the limiting cover 122 are inserted into the limiting groove 124, which can restrict the rotation of the knob 121, thereby restricting the rotation of the rotating rod 120 and the gear 119, so that the scraper 117 stays at a suitable height.

[0037] Therefore, when it is necessary to adjust the thickness of the asphalt coating on the waterproof membrane, the base tire is moved from the stop 114 to the rectangular groove 113 by traction. Then, the limit cover 122 is removed and the knob 121 is rotated, so that the rotating rod 120 drives the gear 119 to rotate, thereby causing the rack 118 to drive the scraper 117 to move up and down, so that the height of the base tire from the bottom of the scraper 117 to the rectangular groove 113 is consistent with the required asphalt thickness. Then, the limit cover 122 is installed. Then, asphalt can be fed into the base tire in the storage bin 111 through the discharge chute 107 and the discharge port 112. The base tire moves by traction, so that the scraper 117 can evenly coat the asphalt on the base tire. This allows the asphalt to be directly and evenly coated on the base tire after processing and extrusion. At the same time, the required asphalt thickness of the waterproof membrane in different types and applications can be controlled without replacing parts.

[0038] like Figure 2-3 As shown, in a preferred embodiment, a feed pipe 102 is fixedly connected to one side of the outer casing 101, and an exhaust pipe 103 is fixedly connected to the other side of the outer casing 101. A motor 104 is inserted and fixedly connected to the top of the outer casing 101. A stirring rod 105 is fixedly connected to the output end of the motor 104. A propeller blade 106 is fixedly installed at the bottom of the stirring rod 105. A discharge trough 107 is provided at the bottom of the outer casing 101. The discharge trough 107 is the same size as the discharge port 112. The discharge trough 107 and the discharge port 112 are located on the same vertical line. A baffle is provided inside the discharge trough 107. 108. The output end of motor 109 is fixedly connected to the side of baffle 108 near the feed pipe 102. The other end of motor 109 is fixedly connected to storage bin 111. The propeller blade 106 fixed at the bottom of the stirring rod 105 conveys and stirs the asphalt in the outer shell 101 to prevent the asphalt from solidifying. Baffle 108 does not seal the asphalt in the outer shell 101. The operation of motor 109 can drive baffle 108 to rotate, thereby adjusting the gap between baffle 108 and discharge chute 107, and then controlling the flow rate of asphalt to storage bin 111.

[0039] Therefore, when there is too much or too little asphalt in the storage bin 111, the motor 2 109 can be used to rotate the baffle 108, and then the gap between the baffle 108 and the discharge chute 107 can be adjusted to control the flow rate of asphalt to the storage bin 111.

[0040] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0041] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
