Description

Technical Field

[0001] The utility model relates to the technical field of cooling and crystallization equipment for engineering resin products, and particularly relates to a multi-layer rotating material receiving and cooling mechanism. Background Art

[0002] When the engineering resin product in chemical production leaves the reaction kettle, it is in a high-temperature molten state and needs to go through a cooling and crystallization process to be transformed into a solid state. When the engineering resin starts to cool, a large amount of smoke will be generated, which needs to be discharged in time through ventilation. After about half an hour of cooling, no more smoke will be generated, but ventilation is still needed to accelerate heat dissipation. During the cooling and crystallization process of the engineering resin, as the temperature decreases, it first forms a high-viscosity fluid from the molten state and finally forms a solid. During the cooling process, the fluidity of the resin becomes poor, and the thermal conductivity will continuously decrease.

[0003] Since the engineering resin will change from the molten state to a high-viscosity fluid and finally to a solid during the cooling and crystallization process, high-efficiency cooling equipment such as heat exchangers or cooling towers cannot be used. The currently used solution is mainly natural cooling in a crystallization tank: install a metal square tank at a fixed position, put the material in the reaction kettle into the tank, and then use a fan to accelerate air circulation and extract the dust generated during cooling. Considering the low thermal conductivity of the engineering resin, to ensure sufficient internal cooling of the resin, the thickness of the resin in the tank is generally about 10 cm. After the cooling and crystallization are completed, workers need to enter the crystallization tank to break and transport the finished resin in the tank. On the basis of this solution, a multi-layer crystallization tank solution has emerged in the industry, that is, multiple layers of crystallization tanks are set vertically to reduce the floor area and improve the space utilization rate in the vertical direction. However, due to the height limitation of the factory building and the need for manual crushing operations, generally only two-layer unit tanks can be set.

[0004] Generally speaking, the current solution has a large floor area. To ensure sufficient internal cooling of the resin, the thickness of the resin in the tank is generally about 10 cm. The current production of engineering resin is relatively high. Even when using a double-layer crystallization tank to process 10 cubic meters of materials, it still needs to occupy an area of 50 square meters; the energy consumption for cooling and crystallization is high. The collection of the finished resin in the crystallization tank requires manual operation, so the internal space height must meet the space for personnel operation. The crystallization tank is large in shape but empty inside, and there is serious waste of resources during ventilation, dust removal, and cooling; the labor intensity of workers is high and the production efficiency is low. Since the area of the crystallization tank is large and the current solution has no automation function, manual collection of the finished resin is required, resulting in high labor intensity and low production efficiency; the cooling time is extremely long. The introduction coefficient of the engineering resin is low. When it enters the crystallization tank for cooling, only the upper surface can conduct convective heat transfer. The current cooling time requires more than 10 hours, which directly leads to the problem of a long production cycle for engineering resin. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a multi-layer rotary material receiving and cooling mechanism, hoping to make up for the deficiencies of the prior art and solve all or part of the problems raised in the above-mentioned background art.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A multi-layer rotary material receiving and cooling mechanism includes an airtight frame, a cooling tank, an air extraction device, a diversion port, a collection device, and an air inlet device. The cooling tank is horizontally arranged inside the airtight frame. The air extraction device is arranged on the top of the airtight frame. The diversion port is arranged on the top of the airtight frame. The collection device is arranged at the lower part of the airtight frame. The air inlet device is arranged at the lower part of the airtight frame.

[0008] The cooling tank includes guide rails, crystallization unit tanks, sprockets, chains, drive shafts, pulleys, and a horizontal drive device. The guide rails are two and are relatively fixed on both sides of the inner wall of the airtight frame. The pulleys are arranged on the guide rails. The ends of the drive shafts are connected to the pulleys and span across the two guide rails. The sprockets are sleeved on the drive shafts. The chains are wound around the sprockets. The crystallization unit tanks are arranged on the outer link sections of the chains. The horizontal drive device is fixed on the airtight frame and is connected to the pulleys. Preferably, there are 4 groups of pulleys, two groups are arranged on the two guide rails respectively. The lower pulley groups can slide back and forth on the rails. A connecting part is arranged on the upper part of the pulleys for fixed connection with the external structure. There are two drive shafts, which respectively span across the two guide rails and are fixed to the connecting parts on the pulleys at the ends. The drive shafts can slide back and forth on the two guide rails along with the pulleys. Further, a rotatable support structure is provided between the two drive shafts to keep the two drive shafts at a constant distance. At least one group of drive shafts is rotated by direct connection with an external driving force, and the rotation drives the chain to rotate. The external driving force can be a motor or other driving devices.

[0009] In an implementation mode that can optimize the foregoing solution, the horizontal drive device includes guide wheels and a towing rope. The guide wheels are arranged on the airtight frame and are in position cooperation with the cooling tank. The towing rope is wound around the guide wheels. The two ends of the towing rope are respectively fixed on the pulleys. There are two groups of guide wheels, which are respectively arranged at the head and tail positions of the airtight frame opposite to the guide rails. The towing rope is wound around the two groups of guide wheels. Further, at least one group of guide wheels is rotated by direct connection with an external driving force. When the guide wheels rotate, they drive the towing rope to rotate around, thereby realizing the reciprocating movement of the chain as a whole and the crystallization unit tanks thereon.

[0010] In an implementation mode that can optimize the foregoing solution, there are several groups of the cooling tanks, which are horizontally arranged inside the airtight frame from top to bottom.

[0011] Further, there are two groups of air inlet devices, which are relatively arranged on both sides of the lower part of the closed frame. The two groups of air inlet devices are relatively arranged to achieve convective air inlet, and are discharged upward through the air extraction device, so as to achieve strong convection in the closed frame, improve the heat exchange efficiency, and further reduce the cooling time.

[0012] In an implementation manner that can optimize the foregoing solution, the collection device includes a belt conveyor mechanism and a collection tank. The collection tank is fixed to the lower side inside the closed frame. The belt conveyor mechanism is arranged below the collection tank and partially penetrates outside the closed frame. The collection tank is funnel-shaped. After the cooled resin is collected through the collection tank, it falls onto the belt conveyor mechanism below and is conveyed outside the equipment.

[0013] Further, the length of the collection tank is greater than the length of the crystallization unit tank. When feeding, it can prevent the raw materials falling from the upper part from falling out of the collection range, increase the subsequent cleaning workload, and further reduce the labor intensity.

[0014] Further, there are four groups of cooling tanks.

[0015] Further, there are seven crystallization unit tanks.

[0016] Further, the vertical projections of the air extraction device and the air inlet device are both within the closed frame and are far away from each other. It can effectively increase the flow path of air circulation, make the temperature inside the equipment drop evenly and quickly, and achieve the purpose of rapid cooling.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] A multi-layer rotating material receiving and cooling mechanism disclosed by the present utility model adopts a multi-layer cooling and crystallization tank structure, divides the large-square crystallization tank into multi-layer crystallization tanks, and reduces the floor area when the thickness of the engineering resin product is not greater than 0.1 m. Each layer of crystallization tank is suspended, so that the upper surface of the engineering resin conducts convective heat dissipation, and the other surfaces conduct heat dissipation through contact with the metal tank, increasing the heat dissipation area and reducing the cooling time. Through blowing air from the bottom and extracting air from the top, air circulates between the multi-layer cooling and crystallization tanks, improving the utilization rate of the vertical space, reasonably arranging the air ducts, and achieving the purpose of energy conservation and environmental protection. Each layer of cooling and crystallization tank is designed as a sprocket rotation mechanism, which can automatically collect the crystallization finished products without the need for operators to enter for collection operations, improving production efficiency, ensuring personnel safety, and reducing labor intensity.

[0042] The cooling tank 2 includes guide rails 21, crystallization unit tanks 22, sprockets 23, chains 24, drive shafts 25, pulleys 26, and a horizontal drive device. The guide rails 21 are two relatively fixed on both sides of the inner wall of the closed frame 1. The pulleys 26 are arranged on the guide rails 21.

[0048] Working principle:

[0049] Taking the cooling mechanism with four layers of cooling tanks as an example:

[0050] Before the engineering resin enters the crystallization unit tank 22, drive each layer of the cooling tank 2 to a predetermined position in advance, and at the same time drive the sprocket 23 to rotate, so that the crystallization unit tank 22 rotates to below the diversion port 4 to make preparations for receiving materials, as Figure 6 shown. When the materials are input, drive the sprocket 23 of the fourth layer to rotate, so that the materials fill all the crystallization unit tanks 22 of the fourth layer in sequence. At this time, pause the input of materials, and drive the crystallization unit tank 22 of the fourth layer to the left position, as Figure 7 shown; then continue to input materials, and drive the sprocket 23 of the third layer to rotate, so that the materials fill all the crystallization unit tanks 22 of the third layer in sequence. Pause the input of materials again, and drive the crystallization unit tank of the third layer to the left position; the second and first layer crystallization unit tanks 22 complete the above feeding work in the same way, as Figure 8 shown.

[0051] After the feeding work is completed, the fans of the air inlet device 6 and the air extraction device 3 start to work, extract the generated soot and waste gas, and accelerate the cooling and crystallization speed of the materials, as Figure 9 shown. After the materials are fully cooled and crystallized, stop the fans and start the collection process.

[0052] The collection process is carried out from bottom to top. Drive the sprocket 23 of the first layer of the cooling tank 2 to rotate, so that the finished materials in the crystallization unit tank 22 are poured into the collection device 5 in sequence, as Figure 10 shown. The collection device 5 is composed of a collection tank 52 and a belt conveyor mechanism 51. The finished materials are transported by the belt conveyor mechanism 51 for packing. After pouring is completed, drive the first layer of the crystallization unit tank 22 to move to the right and return to the original position. At the same time, drive the sprocket 23 to rotate, so that the crystallization unit tank 22 returns to below the diversion port 4, as Figure 11 shown. The second, third, and fourth layer crystallization unit tanks 22 carry out collection and reset in the same way. After the collection work is completed, each layer of mechanism returns to Figure 6 the position, completing a cooling work cycle, and the cooling operation can be carried out again.
