Description

Technical Field

[0001] The utility model belongs to the field of engineering resin product processing in the chemical industry, and in particular relates to a multi-layer cooling crystallization device. Background Art

[0002] Engineering resin products are pure liquid at high temperatures, and as the temperature gradually decreases, they become high-viscosity pastes. When the temperature continues to drop to a certain temperature, they will become brittle solids. When the liquid state changes to a paste state, a large amount of smoke will be generated and needs to be evacuated. In the liquid state, its thermal conductivity is close to 1 / 2 of that of water, and when cooled to a solid state, the thermal conductivity decreases to 1 / 10, so its heat dissipation performance is extremely poor and the crystallization time is long.

[0003] As the output of engineering resin products continues to increase, there is an urgent need for a cooling crystallization tank that can cool quickly and is more energy-saving and environmentally friendly. The characteristics of engineering resin products determine that the current crystallization tanks all adopt the traditional fixed square tank structure. The reactor discharges the material directly into the square tank. Due to the low thermal conductivity, the thickness of the engineering resin product cannot exceed 0.1m, so the area of ​​the metal tank is basically more than 50 square meters. Due to the large floor area, the fan power required for the early exhaust and later cooling is relatively large, and the static cooling and curing time of the discharged engineering resin product is 10-12 hours, resulting in a great waste of data.

[0004] At present, there is only one crystallization tank for engineering resin products. A metal fixed tank with an area of ​​50 to 100 square meters is manufactured and sealed with steel plates so that it can be slowly cooled in this metal tank. A smoke exhaust port is added at the top of the enclosed space of the metal tank, and a ventilator is used to discharge smoke and dust. An air outlet is added on the side to ventilate and cool the engineering resin products. After waiting for cooling to solidify, personnel enter the metal tank through the door to crush and collect, which causes a lot of waste of manpower, material resources and time.

[0005] Existing metal fixing channels have several disadvantages:

[0006] 1. It occupies a large area. In order to meet the needs of heat dissipation and smoke exhaust, 10 cubic meters of engineering resin products require nearly 100 square meters of metal troughs to ensure that the product thickness is no more than 0.1m. It is time-consuming and laborious for workers to carry materials inside, and there are certain safety hazards.

[0007] 2. Cooling crystallization consumes a lot of energy. The cleaning of engineering resin products in the crystallization tank requires human operation. Therefore, the internal space height must meet the operating space of personnel, resulting in a lot of useless work during smoke exhaust, ventilation and cooling, resulting in a waste of resources.

[0008] 3. The cooling time is extremely long. Since it is a fixed groove, only one side has a heat dissipation effect after the product is laid flat. At the same time, the heat dissipation coefficient of the product itself is poor, so the cooling time is basically around 10-12 hours. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0049] like Figure 1-4 As shown, a multi-layer cooling crystallization device includes a steel frame sealed cooling room composed of multi-layer cooling trough guide rails, a roller cooling plate, and a moving mechanism.

[0050] The engineering resin product enters the uppermost cooling tank 61 through the guide tank 4 of the sealed cooling room, and gradually flows into the lower cooling tank 61 after passing through the overflow baffle 62 in the cooling tank 61. After being cooled and solidified through exhaust and ventilation processes, the product is dragged to the outside one by one through the opening and closing door 5 of the sealed cooling room to unload the solidified engineering resin product. The cooling plate 6 is implemented by a moving mechanism, and the lifting platform 96 can meet the needs of dragging and installing multiple cooling plates 6.

[0051] The exhaust port 3 is used to extract smoke and dust in the early stage of the engineering resin product to ensure that the smoke and dust will not enter the atmosphere to pollute the environment. The vent 1 is used for heat exchange and cooling in the later stage to ensure that the cooling and curing of the engineering resin product is completed within the set time, and cooperates with the overflow hole 64 of the cooling plate 6 to form a ring-shaped cooling air duct, which greatly increases the heat dissipation area and improves the heat dissipation efficiency.

[0052] The cooling trough guide rail 2 is used to support the cooling plate 6 and to allow the cooling plate to flexibly operate in the cooling trough guide rail 2 and to allow the cooling plate 6 to be replaced. An upper and lower layer arrangement is adopted to meet the process quantity requirements.

[0053] The opening and closing door 5 is used to seal when exhausting smoke and as an outlet for unloading engineering resin products. Figure 1 As shown, the direction of the cooling air is exactly opposite to the overflow direction of the engineering resin product. The actual production at the bottom level is combined with the design calculation and no overflow occurs.

[0054] The design size of the cooling trough 61 is calculated based on the discharge volume, and the standard is that multiple cooling troughs 61 can accommodate all engineering resin products. Each cooling trough 61 is designed with an overflow baffle 62 to control the thickness of each layer of engineering resin products, which is generally less than 0.1m. Since the engineering resin product is a fluid before cooling, it will automatically flow into the next cooling trough 61 when the thickness exceeds the overflow baffle 62. The rollers 63 are evenly installed on the bottom or side of the cooling plate 6, and can slide freely along the cooling trough guide rail 2 to ensure that the cooling plate 6 can smoothly enter and exit the closed cooling room.

[0055] like Figure 5 As shown, the moving mechanism includes a lifting platform 96 that can be lifted and lowered in a direction parallel to the arrangement direction of the multi-layer cooling plates 6, a connecting rod assembly 93 is slidably installed on the side of the lifting platform 96, and a driving roller 95 is installed on the upper end of the lifting platform 96;

[0056] The connecting rod assembly 93 is a four-link structure, two adjacent connecting rods are connected by a rotating shaft, one of the connecting rods is a first connecting rod 931, and the hinge points of the first connecting rod 931 and the adjacent connecting rod are respectively arranged at one end and the middle, and the automatic end is equipped with a hook shaft 94 that can cooperate with the hook 7;

[0057] Another connecting rod hinged to the end of the first connecting rod 931 is connected to the piston of the hook cylinder 92; the connecting rod assembly 93 is powered by the hook cylinder 92 to swing, and the hook shaft 94 swings with the first connecting rod 931 to generate a trajectory that can intersect with the position of the hook 7;

[0058] Through the power provided by the hook cylinder 92, an extreme position of the connecting rod assembly 93 makes the entire connecting rod assembly 93 located below the plane where the driving roller 95 is located.

[0059] The movable platform 8 can be moved laterally by the guide rails to meet the needs of conveying the cooling plates 6 and switching between the sealed cooling rooms. The lifting platform 96 can be lifted and lowered according to the number of cooling slots 61 at different heights in the sealed room, and after being lifted and lowered to the corresponding height of a cooling plate 6, a relatively horizontal working surface is formed.

[0060] After the cooling plate 6 and the lifting platform reach the same horizontal plane, a hook operation is performed, and a dragging or pushing operation is performed according to the instruction. Through these two operations, the switching between the full cooling plate 6 and the empty cooling plate 6 is completed.

[0061] like Figure 6-8 As shown, the working order of the mobile mechanism 8 to drag the cooling plate 6 is: the lifting platform 96 is lifted and lowered → the connecting rod assembly 93 and the pushing cylinder 91 cooperate to realize the hook operation → drag the cooling plate 6 to the middle position of the lifting platform 96 → unhook to avoid the cooling plate 6 → drive the roller 95 to drive the cooling plate 6 to a stable position → go to the next sequence.

[0062] After the hook cylinder 92 is extended, the hook shaft 94 can reach a height matching the hook 7 through the rotation of the connecting rod assembly 93, and the stroke and lifting height are adjustable.

[0063] After the connecting rod assembly 93 is raised, the propulsion cylinder 91 is extended and pushed to the state where the hook 7 of the cooling plate 6 is engaged with the hook shaft 94. Through the connecting rod clearance characteristic, the hook operation can directly perform the engagement operation.

[0064] After the hook is completed, the push cylinder 91 is restored to drag the cooling plate 6 to the middle position of the lifting platform 96. Due to the presence of the driving roller 95, the push cylinder 91 can be synchronously operated with the power source of the driving roller 95, so that the cooling plate 6 can be moved smoothly.

[0065] After the propulsion cylinder 91 retracts and stops, the driving roller 95 stops driving synchronously, and the hook cylinder 92 retracts to complete the unhooking action of the hook 7. After the hook cylinder 92 retracts to the starting position, the next sequence can be avoided.

[0066] A plurality of driving rollers 95 are installed side by side, and the driving rollers 95 are linked by chains. After the first driving roller 95 is driven, all driving rollers 95 can become driving rollers for moving the cooling plate 6. Driven by the friction force of the driving rollers 95, the cooling plate 6 is gradually moved to the middle position of the lifting platform 96 to prepare for the next process.

[0067] After the engineering resin products in the cooling tank 61 are unloaded, the first step can be repeated to drag out all the cooling plates 6 at once and unload them.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
