Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of conveying equipment for amino mold products, and specifically to a sealed conveying device for amino mold products. Background Technology
[0002] Currently, amino molding compounds are widely used in industries such as electronics, electrical appliances, automobiles, machinery, and daily utensils. Amino molding compound granules are an important thermosetting plastic, mainly prepared from formaldehyde and raw materials such as ammonia or urea through a polycondensation reaction. After preparation, amino molding compound granules need to be conveyed to packaging equipment using conveying equipment. Traditional conveying equipment for amino molding compound granules mostly uses belt conveyors. During the conveying process, amino molding compound granules are prone to spilling from the edge of the conveyor belt, resulting in material loss.
[0003] The attached diagram of the instruction manual Figure 5 The diagram shows a schematic of a sealed conveying device for amino molding compound products in the prior art. It includes a base, a vacuum conveying pump fixedly mounted on top of the base, a conveying pipe fixedly mounted at the inlet end of the vacuum conveying pump, and a discharge pipe fixedly mounted at the outlet end. A vertical discharge pipe is connected to the end of the conveying pipe furthest from the vacuum conveying pump. A storage hopper, connected to the top of the discharge pipe, is fixedly mounted and connected to its interior. The storage hopper is connected to the outlet end of the amino molding compound granule processing equipment. Processed amino molding compound granules fall into the storage hopper and then into the discharge pipe. When conveying the amino molding compound granules, the vacuum conveying pump is activated, drawing air out of the conveying pipe and creating a negative pressure. This draws the amino molding compound granules from the discharge pipe into the conveying pipe, where they are then conveyed by the vacuum conveying pump to the discharge pipe and discharged. This achieves a sealed conveying effect for the amino molding compound granules, effectively preventing them from spilling from the conveyor belt edge and causing material loss. However, in actual use, the following drawbacks still exist:
[0004] Because amino molding compound granules are first extruded into amino molding compound strips during processing, and then the amino molding compound strips are water-cooled and air-cooled to dry before being granulated into amino molding compound granules, although the amino molding compound strips are air-cooled and dried during the granulation process, moisture often remains on the surface of the amino molding compound. This moisture may remain on the surface of the granules, increasing the friction between the amino molding compound granules during the conveying process, making it difficult for the amino molding compound granules to flow freely and reducing the efficiency of the conveying system.
[0005] Therefore, this application proposes a sealed conveying device for amino mold products. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a sealed conveying device for amino mold products, which solves the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A sealed conveying device for amino mold products includes a base, a vacuum conveying pump fixedly installed on the top of the base, a conveying pipe fixedly installed at the inlet end of the vacuum conveying pump and a discharge pipe fixedly installed at the outlet end, and a vertical discharge pipe connected through the end of the conveying pipe away from the vacuum conveying pump, with a storage hopper fixedly installed at the top of the discharge pipe and connected to its interior.

[0011] Furthermore: a slot is provided on the outer wall of the feed pipe and below the conveying pipe. The second filter plate is inserted into the feed pipe along the slot and blocks the air outlet. The second filter plate is fixed to the feed pipe by screws.
[0012] Furthermore: the second filter plate is tightly fitted to the inner wall of the slot, and when the second filter plate is inserted into the feed pipe along the slot, the top of the second filter plate is flush with the bottom wall of the conveying pipe.
[0013] Furthermore: the top of the mounting shell and one side of the electric heating plate are provided with a mounting groove that communicates with the interior of the mounting shell, a filter plate three for sealing the interior of the mounting shell is inserted on the mounting shell and in the mounting groove, and a top plate for sealing the opening end of the mounting groove is hinged on the mounting shell, and the top plate is fixed to the mounting shell by a buckle.

[0016] Furthermore, rubber pads are fixedly installed on both the top plate and the sealing plate. When the top plate and the sealing plate seal the opening end of the mounting groove and the discharge port respectively, both rubber pads come into contact with the mounting shell.
[0017] This utility model provides a sealed conveying device for amino mold products. Compared with the prior art, it has the following advantages:
[0018] 1.

[0020] 3. By setting rubber pads, when the top plate and the sealing plate seal the opening end of the mounting groove and the discharge port respectively, both rubber pads will come into contact with the mounting shell, thereby increasing the fit between the top plate and the sealing plate and the mounting shell, and increasing the sealing effect on the opening end of the mounting groove and the discharge port.

[0029] Example 1
[0030] To address the technical problems in the background art, the following sealed conveying device for amino mold products is provided:
[0031] Combination Figures 1-4 As shown, the sealed conveying device for amino mold products provided by this utility model includes a base 1, a vacuum conveying pump 11 is fixedly installed on the top of the base 1, a conveying pipe 12 is fixedly installed at the inlet end of the vacuum conveying pump 11, a discharge pipe 13 is fixedly installed at the outlet end, and a vertical discharge pipe 14 is connected through the end of the conveying pipe 12 away from the vacuum conveying pump 11. A storage hopper 15 connected to the top of the discharge pipe 14 is fixedly installed.
[0032] A vent hole 141 is provided at the top of the outer wall of the feeding pipe 14. A filter plate 16 is fixedly installed on the feeding pipe 14 and inside the vent hole 141. The filter plate 16 has a side with the largest surface area, which blocks the vent hole 141. Several filter holes, each communicating with the vent hole 141, are provided on the side with the largest surface area of the filter plate 16. A mounting shell 2, communicating with the vent hole 141, is fixedly installed on the outer wall of the feeding pipe 14. A vent hole 142 is provided at the bottom of the feeding pipe 14. A [unclear text - possibly a device or structure] is installed on the feeding pipe 14 and below the conveying pipe 12. A second filter plate 17 is used to block the air outlet 142. The second filter plate 17 has the same structure as the first filter plate 16. A suction mechanism 3 connected to the air outlet 142 is fixedly installed at the bottom of the feed pipe 14. The exhaust end of the suction mechanism 3 is connected to the mounting shell 2. An electric heating plate 4 is fixedly installed inside the mounting shell 2. The electric heating plate 4 has an electric heating wire built into it. When in use, the electric heating wire is energized, and the electric heating wire works to convert electrical energy into heat energy, thereby heating the air inside the mounting shell 2. When this equipment is in use, the storage hopper 15 is connected to the discharge end of the amino molding compound granule processing equipment. The processed amino molding compound granules are then processed. Plastic granules fall into the storage hopper 15 and then into the discharge pipe 14. When conveying the amino molding compound granules, the vacuum pump 11 is activated. The vacuum pump 11 extracts air from the conveying pipe 12, creating a negative pressure within the pipe. This draws the amino molding compound granules from the discharge pipe 14 into the conveying pipe 12, where they are then conveyed by the vacuum pump 11 to the discharge pipe 13 and discharged. This achieves a sealed conveying effect for the amino molding compound granules. By using an electric heating plate 4 and an air extraction mechanism 3, the operation of the electric heating plate 4 and the air extraction mechanism 3 is controlled during the conveying of the amino molding compound granules. The system heats the air inside the mounting housing 2, and the air extraction mechanism 3 draws the air out of the discharge pipe 14 and then transports it into the mounting housing 2. The air inside the mounting housing 2 enters the discharge pipe 14 through the filter holes on the filter plate 16 to allow air circulation. When the air circulates, the hot air inside the mounting housing 2 is transported into the discharge pipe 14, thereby achieving the drying effect on the amino molding compound granules falling into the discharge pipe 14. This effectively avoids the situation where moisture increases the friction between the amino molding compound granules during the conveying process, making it difficult for the amino molding compound granules to flow freely, thus improving the efficiency of the conveying system.
[0033] Example 2
[0034] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:
[0035] In this embodiment, the air extraction mechanism 3 includes a fixed housing 31 fixedly installed at the bottom of the feed pipe 14. The bottom of the fixed housing 31 has a mounting hole 32 that communicates with the air outlet 142. An exhaust fan 33 is fixedly installed on the fixed housing 31 and inside the mounting hole 32. An exhaust pipe 34 that communicates with the mounting hole 32 is fixedly installed at the bottom of the fixed housing 31. The other end of the exhaust pipe 34 is connected to the inside of the mounting housing 2. In use, the exhaust fan 33 is controlled to work, extracting air from the mounting hole 32 and delivering it to the exhaust pipe 34. Air in the mounting housing 2 enters the mounting hole 32 through the air outlet 142. The air circulates into the mounting housing 2 and is then delivered to the feed pipe 14 through the vent hole 141, thereby achieving an internal air circulation effect between the feed pipe 14, the mounting hole 32, the exhaust pipe 34, and the mounting housing 2.
[0036] In this embodiment, a slot 143 is provided on the outer wall of the feed pipe 14 and below the conveying pipe 12. The filter plate 17 is inserted into the feed pipe 14 along the slot 143 and blocks the air outlet 142. The filter plate 17 is fixed to the feed pipe 14 by screws, thereby achieving the effect of fixing the filter plate 17 to the feed pipe 14. By setting the filter plate 17 to be inserted into the feed pipe 14 along the slot 143, it is convenient to install and remove the filter plate 17, and to disassemble and replace the filter plate 17.
[0037] In this embodiment, the filter plate 17 is tightly fitted to the inner wall of the slot 143, increasing the fit between the filter plate 17 and the slot 143. When the filter plate 17 is inserted into the feed pipe 14 along the slot 143, the top of the filter plate 17 is flush with the bottom wall of the conveying pipe 12. By setting the top of the filter plate 17 to be flush with the bottom wall of the conveying pipe 12, it is beneficial for the amino molding compound particles falling on the filter plate 17 to be more completely conveyed to the discharge pipe 13 through the conveying pipe 12.
[0038] Example 3
[0039] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:
[0040] In this embodiment, a mounting groove 21 communicating with the interior of the mounting shell 2 is provided on the top of the mounting shell 2 and on one side of the electric heating plate 4. A filter plate 22 for sealing the interior of the mounting shell 2 is inserted on the mounting shell 2 and in the mounting groove 21. The filter plate 22 is made of high efficiency filter. In use, the exhaust fan 33 works to circulate air in the feeding pipe 14, the fixed shell 31, the exhaust pipe 34 and the mounting shell 2. When the amino molding compound particles falling into the feeding pipe 14 are dried, the moisture on the surface of the amino molding compound particles evaporates, causing some fine particles to fall off and form dust. Some of the dust passes through the filter plate 2. The filter holes on 7 enter the exhaust pipe 34, and then enter the mounting shell 2. When the air flows into the feed pipe 14 inside the mounting shell 2, it comes into contact with the filter plate 22. The filter plate 22 can filter the dust in the air, so that the dust remains in the mounting shell 2, thus achieving the effect of collecting the dust generated during the drying of amino molding compound granules. The mounting shell 2 is hinged with a top plate 23 for sealing the opening end of the mounting groove 21, thus achieving the effect of sealing the opening end of the mounting groove 21. The top plate 23 is fixed to the mounting shell 2 by a buckle, which makes it easy to fix or remove the fixation between the top plate 23 and the mounting shell 2.
[0041] In this embodiment, a discharge port 24 communicating with the interior is provided at the bottom of the mounting shell 2 on the side of the mounting groove 21 away from the discharge pipe 14. A sealing plate 25 for sealing the discharge port 24 is hinged to the mounting shell 2. The sealing plate 25 is fixed to the mounting shell 2 by a second buckle, which facilitates fixing or unfixing the sealing plate 25 to the mounting shell 2. In use, the filter plate 22 filters dust in the air, so that the dust remains in the mounting shell 2 on the side of the filter plate 22 away from the discharge pipe 14. When it is necessary to clean the dust collected in the mounting shell 2, the fastener is removed from fixing the sealing plate 25 to the mounting shell 2, so that the sealing plate 25 can rotate on the mounting shell 2, and the sealing of the discharge port 24 is removed. The dust collected in the mounting shell 2 can then be discharged through the discharge port 24, thereby achieving the cleaning effect of the dust collected in the mounting shell 2. The operation is simple.
[0042] In this embodiment, a solid flow meter 5 is fixedly installed on the end of the conveying pipe 12 near the discharge pipe 14, and a solid flow meter 6 is fixedly installed on the end of the discharge pipe 13 near the vacuum conveying pump 11. Both solid flow meters 5 and 6 are model 3U-DLD / DLM5. Solid flow meters 5 and 6 are communicatively connected to a PLC control system. By setting solid flow meters 5 and 6, when conveying amino molding compound granules, the amino molding compound granules move in the conveying pipe 12 toward the discharge pipe 13 and are discharged through the discharge pipe 13. During this process, solid flow meters 5 and 6 respectively monitor the flow rate of amino molding compound granules in the conveying pipe 12 and the discharge pipe 13 in real time.
[0043] In this embodiment, rubber pads 7 are fixedly installed on both the top plate 23 and the sealing plate 25. When the top plate 23 and the sealing plate 25 seal the opening end of the mounting groove 21 and the discharge port 24 respectively, both rubber pads 7 abut against the mounting shell 2. By setting the rubber pads 7, when the top plate 23 and the sealing plate 25 seal the opening end of the mounting groove 21 and the discharge port 24 respectively, both rubber pads 7 abut against the mounting shell 2, thereby increasing the fit between the top plate 23 and the sealing plate 25 and the mounting shell 2, and increasing the sealing effect on the opening end of the mounting groove 21 and the discharge port 24.
