Description

Technical Field

[0001] This application relates to the field of wet-mixed mortar production, and in particular to a raw material drying device for wet-mixed mortar production. Background Technology

[0002] Wet-mixed mortar refers to a mortar product made by mixing cement, fine aggregates, admixtures and additives in a certain proportion, stirring evenly by a professional manufacturer, transporting it to the place of use by a special transport vehicle, and using it within a specified time. In the production process of wet-mixed mortar, the drying of raw materials is one of the key steps, and the raw materials are often dried using drying equipment.

[0003] An existing Chinese patent (publication number: CN220018077U) discloses a raw material drying device for wet-mixed mortar production, including a support frame. A wet-mixed mortar raw material drying box is fixedly installed on the top of the support frame, and a feed hopper is fixedly installed on the left side of the upper surface of the wet-mixed mortar raw material drying box. When the raw materials for wet-mixed mortar production to be processed are spread out, the adjusting screws are rotated using a tool. Under the action of the flywheel and V-belt, multiple adjusting screws are rotated, thereby adjusting the height of the slider seat plate. This allows control over the spreading thickness of the raw materials for wet-mixed mortar production. Furthermore, the guide rod and support spring allow the spreading plate to have a certain vertical movement during the spreading of the raw materials, thereby improving the spreading effect and reducing damage to the spreading plate.

[0004] In actual use, when raw materials are fed into the hopper and then enter the conveying mechanism, the material tends to pile up because the size of the hopper's outlet is fixed. Although the material is subsequently spread out using a spreading plate, when there is a large accumulation, the material tends to pile up on the spreading plate, which may result in some of the material not achieving the desired drying effect due to insufficient heating. Utility Model Content

[0005] The purpose of this application is to solve the problem mentioned in the background art that when raw materials enter the conveying mechanism from the feed hopper, they tend to pile up. Although the raw materials are subsequently spread out using a spreading plate, when there is a large amount of accumulation, the raw materials tend to pile up on the spreading plate, resulting in some raw materials failing to achieve the desired drying effect due to insufficient heating. This application provides a raw material drying device for wet-mixed mortar production.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A raw material drying device for wet-mixed mortar production includes a drying chamber with four symmetrically arranged support legs fixed at the bottom. A conveyor frame is fixed inside the drying chamber, and a conveyor belt is installed on the conveyor frame. A feed hopper is fixed on the drying chamber, and a dispersing mechanism is provided between the feed hopper and the conveyor belt. An auxiliary scraping mechanism is provided on the conveyor belt. A uniformly distributed exhaust grid is provided on the drying chamber, and a maintenance door is installed on one side of the drying chamber.

[0008] By adopting the above technical solution, the raw material enters the drying chamber from the feeding hopper, and then passes through the dispersing mechanism. The dispersing mechanism evenly disperses the raw material onto the conveyor belt on the conveyor frame. Then the conveyor belt drives the raw material to move in the drying chamber, thereby reducing the possibility of the raw material piling up on the conveyor belt when it enters from the feeding hopper, and further improving the drying effect of the raw material.

[0009] Furthermore, the dispersing mechanism includes a conveying pipe disposed on a conveyor belt, a dispersing plate fixed at one end of the conveying pipe, the dispersing plate being fan-shaped, uniformly distributed partitions fixed on the dispersing plate, and a vibration component disposed on the dispersing plate.

[0010] By adopting the above technical solution, the raw materials in the feed hopper are moved from the conveying pipe to the dispersing plate. Under the action of the partition on the dispersing plate, the raw materials are spread out in a fan shape, which allows the raw materials to fall evenly on the conveyor belt, reducing the possibility of raw materials piling up on the conveyor belt and further improving the drying effect of the raw materials.

[0011] Furthermore, the vibration assembly includes a support frame fixed to the dispersion plate, a dispersion motor fixed on the support frame, and an eccentric wheel fixed to the output end of the dispersion motor.

[0012] By adopting the above technical solution, the dispersing motor drives the eccentric wheel to rotate, causing the support frame to vibrate, which in turn causes the dispersing plate to vibrate, allowing the raw materials to move along the dispersing plate.

[0013] Furthermore, a support column 1 is provided on both sides of the conveying pipe, and a support column 2 is provided on both sides of the dispersing plate. A vibrating rod is provided between the two support columns 1 and 2. The two vibrating rods are fixedly connected to the corresponding conveying pipe and dispersing plate, respectively. The support columns 1 and 2 are both fixedly connected to the conveying frame.

[0014] By adopting the above technical solution, the corresponding vibrating rods are supported by support column one and support column two, which makes it convenient to tilt and support the conveying pipe and the dispersion plate.

[0015] Furthermore, support springs are fixed on both support column one and support column two, and the support springs are fixedly connected to the vibration rod.

[0016] By adopting the above technical solution, the vibration rod is supported by the support springs on support column one and support column two, so that the dispersion plate can vibrate normally under the support of the support springs.

[0017] Furthermore, a corrugated pipe is provided between the conveying pipe and the feed hopper, and both ends of the corrugated pipe are fixedly connected to the conveying pipe and the feed hopper.

[0018] By adopting the above technical solution, using a corrugated pipe to connect the feed hopper and the conveying pipe, the possibility of raw materials falling between the feed hopper and the conveying pipe when the conveying pipe vibrates can be reduced.

[0019] Furthermore, the auxiliary scraping mechanism includes two baffles symmetrically fixed on the dispersing plate, a support rod is provided between the two baffles, a scraping plate is fixed on the support rod, and an adjustment component is provided between the support rod and the two baffles.

[0020] By adopting the above technical solution, the raw materials on the conveyor belt are leveled using a scraper plate, thereby further improving the uniformity of the raw material distribution on the conveyor belt.

[0021] Furthermore, the adjustment assembly includes two symmetrically slidingly connected adjustment frames at both ends of the support rod. The two adjustment frames are fixedly connected to corresponding baffles. An adjustment threaded rod is rotatably connected to one of the adjustment frames. The adjustment threaded rod passes through the support rod and is threadedly connected to the support rod.

[0022] By adopting the above technical solution, the adjusting threaded rod can be directly rotated, which in turn drives the support rod, thereby allowing the support rod to easily move the scraper plate up and down between the two baffles.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the raw material enters the drying chamber from the feed hopper, it first enters the corrugated pipe, then the conveying pipe, and then moves to the dispersing plate. At the same time, the dispersing motor drives the eccentric wheel to rotate. Under the action of the eccentric wheel, the support frame drives the dispersing plate. The dispersing plate transmits vibration to the vibrating rod, which in turn transmits it to the support springs on support column one and support column two. The dispersing plate vibrates under the support of the support springs, and the raw material is dispersed along the dispersing plate by the partition, so that the raw material falls evenly on the conveyor belt. This achieves the purpose of ensuring that the raw material falls evenly on the conveyor belt, reducing the possibility of raw material piling up on the conveyor belt, and further improving the drying effect of the raw material.

[0025] 2. In this application, when the raw material falls evenly onto the conveyor belt, the conveyor belt drives the raw material to move. During the movement, the raw material passes through a scraper plate, which scrapes the raw material on the conveyor belt to level it, allowing the raw material to be spread more evenly on the conveyor belt. When it is necessary to adjust the thickness of the scraped raw material, the adjusting threaded rod is directly rotated. The adjusting threaded rod drives the support rod, which moves on two adjusting frames. The support rod drives the scraper plate to rise and fall between two baffles. At the same time, the baffles block the two sides of the dispersing plate, thereby achieving the purpose of further improving the uniformity of the raw material distribution on the conveyor belt and adjusting the scraping thickness.

[0033] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0034] This application discloses a raw material drying device for wet-mixed mortar production.

[0035] Reference Figure 1 , Figure 2 and Figure 3A raw material drying device for wet-mixed mortar production includes a drying chamber 1, four symmetrical support legs 2 fixed at the bottom of the drying chamber 1, a conveyor frame 9 fixed inside the drying chamber 1, a conveyor belt 3 installed on the conveyor frame 9, a feed hopper 4 fixed on the drying chamber 1, a dispersing mechanism 5 between the feed hopper 4 and the conveyor belt 3, an auxiliary scraping mechanism 6 on the conveyor belt 3, a uniformly distributed exhaust grid 7 on the drying chamber 1, and a maintenance door 8 installed on one side of the drying chamber 1.

[0036] When using this raw material drying device, the raw material to be dried is fed into the feed hopper 4, and then the raw material enters the drying chamber 1 from the feed hopper 4. After passing through the dispersion mechanism 5, the dispersion mechanism 5 evenly disperses the raw material onto the conveyor belt 3 on the conveyor frame 9. Then the conveyor belt 3 drives the raw material to move in the drying chamber 1. During the process of the conveyor belt 3 driving the raw material to move, the auxiliary scraping mechanism 6 scrapes the raw material on the conveyor belt 3 to level it. The drying equipment in the drying chamber 1 dries the raw material, and then the raw material comes out from the discharge port of the drying chamber 1, completing the drying of the raw material. By allowing the raw material to be dried to enter the drying chamber 1 from the feed hopper 4 and pass through the dispersion mechanism 5, the dispersion mechanism 5 evenly disperses the raw material onto the conveyor belt 3, thereby reducing the possibility of the raw material piling up on the conveyor belt 3 when it enters from the feed hopper 4, and further improving the drying effect of the raw material.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The dispersing mechanism 5 includes a conveying pipe 51 disposed on the conveyor belt 3, a dispersing plate 52 fixed at one end of the conveying pipe 51, the dispersing plate 52 being fan-shaped, a uniformly distributed partition plate 53 fixed on the dispersing plate 52, and a vibration component 54 disposed on the dispersing plate 52.

[0038] In addition, the vibration assembly 54 includes a support frame 541 fixed on the dispersion plate 52, a dispersion motor 542 fixed on the support frame 541, and an eccentric wheel 543 fixed at the output end of the dispersion motor 542.

[0039] Furthermore, support columns 1 544 are provided on both sides of the conveying pipe 51, and support columns 2 545 are provided on both sides of the dispersing plate 52. Vibration rods 546 are provided between the two support columns 1 544 and the two support columns 2 545. The two vibration rods 546 are fixedly connected to the corresponding conveying pipe 51 and the dispersing plate 52 respectively. Support columns 1 544 and support columns 2 545 are fixedly connected to the conveying frame 9.

[0040] Furthermore, support springs 547 are fixed on both support column 1 544 and support column 2 545, and the support springs 547 are fixedly connected to the vibration rod 546.

[0041] Furthermore, a corrugated pipe 55 is provided between the conveying pipe 51 and the feed hopper 4, and both ends of the corrugated pipe 55 are fixedly connected to the conveying pipe 51 and the feed hopper 4.

[0042] When the raw material enters the drying chamber 1 from the feed hopper 4, it first enters the corrugated pipe 55, then from the corrugated pipe 55 into the conveying pipe 51, and then moves from the conveying pipe 51 to the dispersing plate 52. At the same time, the dispersing motor 542 drives the eccentric wheel 543 to rotate. Under the action of the eccentric wheel 543, the support frame 541 drives the dispersing plate 52. The dispersing plate 52 transmits vibration to the vibrating rod 546, which in turn transmits it to the support springs 547 on the first support column 544 and the second support column 545. The dispersing plate 52 vibrates under the support of the support springs 547, causing the raw material to spread along the dispersing plate 52 under the separation of the partition plate 53, so that the raw material falls evenly onto the conveyor belt 3. By allowing the raw material from the feed hopper 4 to fall onto the conveyor belt 3, the raw material is vibrated on the dispersing plate 52 and dispersed by the partition plate 53, so that the raw material falls evenly onto the conveyor belt 3, reducing the possibility of raw material piling up on the conveyor belt 3, and further improving the drying effect of the raw material.

[0043] Reference Figure 3 and Figure 5 The auxiliary scraping mechanism 6 includes two baffles 61 symmetrically fixed on the dispersing plate 52, a support rod 62 is provided between the two baffles 61, a scraping plate 63 is fixed on the support rod 62, and an adjustment component 64 is provided between the support rod 62 and the two baffles 61.

[0044] In addition, the adjustment assembly 64 includes two symmetrically slidingly connected adjustment frames 641 at both ends of the support rod 62. The two adjustment frames 641 are fixedly connected to the corresponding baffles 61. An adjustment threaded rod 642 is rotatably connected to one of the adjustment frames 641. The adjustment threaded rod 642 passes through the support rod 62 and is threadedly connected to the support rod 62.

[0045] When the raw material falls evenly onto the conveyor belt 3, the conveyor belt 3 moves the raw material. During the movement, the raw material passes through the scraper plate 63, which flattens the raw material on the conveyor belt 3, allowing the raw material to be spread more evenly on the conveyor belt 3. When it is necessary to adjust the thickness of the flattened raw material, simply rotate the adjusting threaded rod 642. The adjusting threaded rod 642 drives the support rod 62, which moves on the two adjusting frames 641. The support rod 62 drives the scraper plate 63 to rise and fall between the two baffles 61. At the same time, the baffles 61 block the two sides of the dispersing plate 52. By allowing the raw material on the dispersing plate 52 to fall onto the conveyor belt 3, the scraper plate 63 flattens the raw material on the conveyor belt 3, thereby further improving the uniformity of the raw material distribution on the conveyor belt 3.

[0046] Working principle: When using this raw material drying device, the raw material to be dried is fed into the feed hopper 4, then enters the drying chamber 1 from the feed hopper 4, and then enters the conveying pipe 51 through the corrugated pipe 55. The material then moves from the conveying pipe 51 to the dispersing plate 52. Simultaneously, the dispersing motor 542 drives the eccentric wheel 543 to rotate. Under the action of the eccentric wheel 543, the support frame 541 drives the dispersing plate 52. The dispersing plate 52 transmits vibration to the vibrating rod 546, which in turn transmits it to the supports on the first support column 544 and the second support column 545. Support spring 547 causes the dispersing plate 52 to vibrate under the support of the support spring 547, causing the raw material to spread along the dispersing plate 52 under the separation of the partition plate 53, so that the raw material falls evenly onto the conveyor belt 3. The conveyor belt 3 drives the raw material to move. During the movement, the raw material passes through the scraper plate 63, which scrapes the raw material on the conveyor belt 3 to flatten it, so that the raw material can be spread more evenly on the conveyor belt 3. Then the conveyor belt 3 drives the raw material to move, and the drying equipment in the drying chamber 1 dries the raw material. Then the raw material comes out from the discharge port of the drying chamber 1, completing the drying of the raw material.
