Description

Technical Field

[0001] This application relates to the field of plastic pellet processing technology, and particularly to a water tank of a granulating dehydrator. Background Art

[0002] A granulator is an industrial device used to form solid pellets from powdery or granular materials, and is widely used in fields such as chemical industry, petrochemical industry, pharmaceutical industry, and food industry. The working principle of the granulator varies according to different types, and common ones include pressure granulators, extrusion granulators, and rotary granulators.

[0003] During the production process of plastic pellets, in order to achieve rapid cooling and dehydration of the pellets, the pellets output from the granulator are usually input into the water tank of the granulating dehydrator, and cooling water is passed into the water tank. Heat exchange occurs between the pellets and the cooling water during the movement of the pellets along with the cooling water.

[0004] However, most of the existing water tanks are strip-shaped tanks. With the flow of the cooling water in the water tank, the flow rate of the pellets is relatively fast, which is not conducive to the rapid cooling of the pellets and easily leads to the situation of agglomeration of the plastic pellet material due to insufficient cooling in the next process. Utility Model Content

[0005] In order to improve the cooling effect of the pellet material in the water tank and reduce the situation of agglomeration of the plastic pellet material due to insufficient cooling in the next process, this application provides a water tank of a granulating dehydrator.

[0006] The water tank of the granulating dehydrator provided by this application adopts the following technical solutions:

[0007] A water tank of a granulating dehydrator includes a cooling tank body. A plurality of folding blocking parts are arranged on the inner wall of the cooling tank body. The folding blocking parts have folding blocking surfaces, and the folding blocking surfaces are arranged in a zigzag manner and are connected to the inner wall of the cooling tank body. The plurality of folding blocking parts are arranged at intervals along the length direction of the cooling tank body.

[0008] By adopting the above technical solutions, the plastic pellet material output from the granulator enters the water tank of the dehydrator and moves together with the cooling water in the water tank. During the movement, the folding blocking parts are used to block the pellet material to a certain extent, prolong the residence time of the pellet material in the cooling water tank, improve the cooling effect of the pellet material in the water tank, and further reduce the situation of agglomeration of the pellet material due to insufficient cooling in the next process.

[0009] Optionally, the cooling tank body includes two tank side walls and a tank bottom wall. The two tank side walls are respectively connected to both sides of the tank bottom wall. The tank side wall includes a plurality of arc-shaped plates, and the plurality of arc-shaped plates are connected end to end. The concave parts of any two adjacent arc-shaped plates corresponding to one tank side wall all point to the other tank side wall.

[0010] By adopting the above technical solution, during the movement of the granular material, under the guiding action of the arc-shaped folding baffle surface corresponding to one side wall of the trough, the granular material moves along the tangent direction of the guiding surface, moves to the folding baffle surface corresponding to the opposite side wall of the trough, and then returns to the next folding baffle surface corresponding to the side wall of the trough under the guiding action of the opposite folding baffle surface. The arc-shaped surface has a certain guiding effect. Therefore, even if the folding baffle part forms a certain blockage to the granular material, it can ensure the smooth flow of the granular material in the cooling trough body.

[0011] Optionally, the arc-shaped plates corresponding to the two side walls of the trough are arranged staggeredly.

[0012] By adopting the above technical solution, although the cooling trough body has a certain width change, the width change is small, ensuring that the flow rate of the cooling water in the cooling water trough is relatively uniform, thereby ensuring that the moving speed of the granular material in the cooling water trough is relatively uniform, and reducing the situation where multiple granular materials gather and agglomerate at a certain place in the cooling water trough before the cooling is completed.

[0013] Optionally, the cooling trough body includes two side walls and a bottom wall, and the two side walls are respectively connected to both sides of the bottom wall; the side wall includes a plurality of flat plates, and the plurality of flat plates are arranged end to end along the length direction of the bottom wall, and the dihedral angle formed between the plate surfaces of adjacent flat plates is an obtuse angle.

[0014] Optionally, the folding baffle part is arranged on the inner bottom wall of the cooling trough body.

[0015] Optionally, the folding baffle part is arranged in a wavy shape.

[0016] By adopting the above technical solution, the folding baffle surface is arranged in an arc shape, reducing the folding angle and ensuring the smooth movement of the granular material.

[0017] Optionally, it further includes an aggregate trough body, which is arranged at one end of the cooling trough body far from the threshing machine and is communicated with the cooling trough body. The trough wall of the aggregate trough body is provided with dehydration holes, and the aperture of the dehydration holes is smaller than the diameter of the granular material.

[0018] Optionally, the cooling trough body includes two side walls and a bottom wall, and a plurality of movable rods are hinged to both of the two side walls; the direction in which the movable rods rotate relative to the cooling trough body is along the length direction of the cooling trough body, and the plurality of movable rods are arranged at intervals along the length direction of the cooling trough body; the end of the movable rod located above the cooling trough body is connected with a knocking piece, and the end of the movable rod located outside the cooling trough body is hinged to the output end of the driving cylinder.

[0019] By adopting the above technical solution, when the granular material moves in the cooling water tank, multiple driving cylinders are started. The driving cylinders drive the movable rods to rotate, and the movable rods drive the knocking parts to knock the granular material in the cooling water tank, pushing the floating granular material to the bottom of the cooling water tank, increasing the contact between the granular material and the cooling water, and improving the cooling effect.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. By arranging the folding and blocking part in the cooling water tank, the granular material stays in the cooling tank body for a longer time, improving the cooling effect of the granular material in the water tank, and thus reducing the situation of agglomeration of the granular material due to insufficient cooling in the next process;

[0022] 2. The tank side wall of the cooling water tank includes multiple arc-shaped plates, and the adjacent arc-shaped plates are arranged end to end, so that even if the folding and blocking part forms a certain block on the granular material, it can ensure the smooth flow of the granular material in the cooling tank body;

[0023] 3. The arc-shaped plates corresponding to the two tank side walls are arranged staggeredly, ensuring that the flow rate of the cooling water in the cooling water tank is relatively uniform, so as to ensure that the moving speed of the granular material in the cooling water tank is relatively uniform, and reducing the situation of multiple granular materials aggregating and agglomerating at a certain place in the cooling water tank before the cooling is completed.

[0031] The following is combined with the attached Figures 1-6A further detailed description of the present application is provided.

[0032] An embodiment of the present application discloses a water tank of a granulating dehydrator.

[0033] Embodiment 1

[0034] Referring to Figure 1 , a water tank of a granulating dehydrator includes a cooling tank body 1 and an aggregate tank body 2. The cooling tank body 1 is used to receive the granular material output from the granulator. The aggregate tank body 2 is connected to one end of the cooling tank body 1 away from the thresher, and the aggregate tank bottom is used to collect the granular material after cooling and dehydration.

[0035] The cooling tank body 1 includes two tank side walls 11 and a tank bottom wall 12. The two tank side walls 11 are respectively connected to both sides of the tank bottom wall 12, and the two tank side walls 11 are arranged opposite to each other.

[0036] In this embodiment, the tank side wall 11 includes a plurality of arc-shaped plates 13. The plurality of arc-shaped plates 13 are arranged end to end along the length direction of the cooling tank body 1. The concave portions of any two adjacent arc-shaped plates 13 corresponding to one tank side wall 11 all point to the other tank side wall 11. After the adjacent arc-shaped plates 13 are connected to each other, a plurality of folding blocking portions 15 are formed and arranged at intervals along the length direction of the cooling tank body 1. The folding blocking portion 15 has a folding blocking surface arranged in a zigzag manner.

[0037] The plastic granular material output from the granulator enters the water tank of the dehydrator and moves together with the cooling water in the water tank. During the moving process, under the guiding action of the arc-shaped folding blocking surface corresponding to one tank side wall 11, the granular material moves along the tangent direction of the guiding surface, moves to the folding blocking surface corresponding to the tank side wall 11 opposite to this tank side wall 11, and then returns to the next folding blocking surface corresponding to this tank side wall 11 under the guiding action of the folding blocking surface on the opposite side. As a result, the granular material stays in the cooling tank body 1 for a longer time, improving the cooling effect of the granular material in the water tank, and further reducing the situation that the granular material agglomerates due to insufficient cooling in the next process.

[0038] Moreover, in this embodiment, since the folding blocking surface is arranged in an arc shape and the arc surface has a certain guiding effect, even if the folding blocking portion 15 forms a certain blockage to the granular material, it can still ensure the smooth flow of the granular material in the cooling tank body 1.

[0039] Furthermore, in this embodiment, the arc-shaped plates 13 corresponding to the two tank side walls 11 are arranged in a staggered manner, so that although the cooling tank body 1 has a certain width change, the width change is small, ensuring that the flow rate of the cooling water in the cooling water tank is relatively uniform, and thus ensuring that the moving speed of the granular material in the cooling water tank is relatively uniform, reducing the situation that multiple granular materials agglomerate at a certain place in the cooling water tank before the cooling is completed.

[0040] It is understandable that in other embodiments, the arc-shaped plates 13 of the two groove side walls 11 can also be arranged opposite to each other in pairs.

[0041] A plurality of dehydration holes 21 are formed through the bottom wall of the aggregate water tank. The plurality of dehydration holes 21 are evenly distributed on the bottom wall of the aggregate water tank, and the aperture of the dehydration holes 21 is smaller than the diameter of the granular material. A water collecting tank can be placed below the aggregate water tank. After the granular material and the cooling water move into the aggregate water tank, the cooling water falls into the water collecting tank below through the dehydration holes 21, and the granular material remains in the aggregate water tank to facilitate the next process.

[0042] The implementation principle of Embodiment 1 is as follows: The plastic granular material output from the granulator enters the water tank of the dehydrator and moves together with the cooling water in the water tank. During the movement, under the guiding action of the arc-shaped folding surface corresponding to one of the groove side walls 11, the granular material moves along the tangent direction of the guiding surface and moves to the folding surface corresponding to the groove side wall 11 opposite to this groove side wall 11. Then, under the guiding action of the opposite folding surface, it returns to the next folding surface corresponding to this groove side wall 11.

[0043] After the granular material and the cooling water move into the aggregate water tank, the cooling water falls into the water collecting tank below through the dehydration holes 21, and the granular material remains in the aggregate water tank to facilitate the next process.

[0044] Embodiment 2

[0045] Referring to Figure 2 , the difference between this embodiment and Embodiment 1 is that the cooling tank body 1 is arranged in a straight strip shape, and the folding part 15 is connected to the inner wall of the cooling tank body 1. The folding part 15 and the inner wall of the cooling tank body 1 can be fixedly connected or detachably connected.

[0046] In this embodiment, the folding part 15 is arranged in a hemispherical shape so that the folding surface is in an arc shape to facilitate guiding the granular material.

[0047] In other embodiments, the folding part 15 can also be other polyhedrons or semi-polyhedrons.

[0048] Embodiment 3

[0049] Referring to Figure 3 , the difference between this embodiment and Embodiment 1 is that the groove side wall 11 includes a plurality of flat plates 14, and the plurality of flat plates 14 are arranged end to end along the length direction of the groove bottom wall 12, and the dihedral angle formed between the plate surfaces of adjacent flat plates 14 is an obtuse angle.

[0050] In this embodiment, the flat plates 14 corresponding to the two groove side walls 11 are arranged in an interlaced manner.

[0051] Referring to Figure 4, in other embodiments, the flat plates 14 corresponding to the two groove side walls 11 can also be arranged opposite to each other one by one.

[0052] Embodiment 4

[0053] Refer to Figure 5 , the difference between this embodiment and Embodiment 1 is that the folding baffle 15 is arranged on the bottom inner wall of the cooling tank 1. In this embodiment, the baffle plate is arranged in a wavy shape.

[0054] Embodiment 5

[0055] Refer to Figure 6 , the difference between this embodiment and Embodiment 1 is that a plurality of movable rods 3 are hinged to both groove side walls 11; the direction in which the movable rods 3 rotate relative to the cooling tank 1 is along the length direction of the cooling tank 1, and the plurality of movable rods 3 are arranged at intervals along the length direction of the cooling tank 1; a knocking member 31 is connected to the end of the movable rod 3 located above the cooling tank 1, and the end of the movable rod 3 located outside the cooling tank 1 is hinged to the output end of the driving cylinder 4.

[0056] When the granular material moves in the cooling water tank, start a plurality of driving cylinders 4, use the driving cylinders 4 to drive the movable rods 3 to rotate, and the movable rods 3 drive the knocking members 31 to knock the granular material in the cooling water tank, and push the floating granular material to the bottom of the cooling water tank, increasing the contact between the granular material and the cooling water and improving the cooling effect.

[0057] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
