Description

Technical Field

[0001] This utility model relates to the field of cooling spiral machine technology, and in particular to a cover plate cooling spiral machine. Background Technology

[0002] The existing cover plate cooling screw press includes a hollow tube body, a hollow cover plate, and a screw shaft. The hollow cover plate covers the top of the hollow tube body. When the screw press is working, the material to be cooled enters the hollow tube body through the feed port and then cooling water is added through the water inlet of the hollow cover plate. The rotation of the screw shaft drives the material to rotate together. During the rotation, the material comes into contact with the bottom of the hollow cover plate, which accelerates the cooling of the material. The existing hollow cover plate is a hollow cuboid, and the area of ​​the material in contact with the hollow cover plate during rotation is small, resulting in low efficiency of the hollow cover plate in accelerating the cooling of the material.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model discloses a cover plate cooling spiral machine to solve the problem that the area of ​​material in contact with the hollow cover plate during rotation is small, resulting in low efficiency of the hollow cover plate in accelerating material cooling.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A cover plate cooling spiral compressor includes:

[0007] The hollow tube is a semi-frame shape with an opening at the top. The hollow tube has an inlet on the left side and an outlet on the right side.

[0008] A helical body, which is rotatably mounted inside the hollow tube;

[0009] A hollow cover plate is provided on the opening at the top of the hollow tube body. The hollow cover plate has a first water inlet on the left side and a first water outlet on the right side. The bottom end of the hollow cover plate extends into the hollow tube body, and the longitudinal section of the bottom end of the hollow cover plate is a downward-opening arc.

[0010] A further technical solution is that the hollow cover plate includes a top plate, two side plates and a bottom plate. The top ends of the two side plates are respectively connected to the bottom ends of the front and rear sides of the top plate. The longitudinal section of the bottom plate is an arc with an opening facing downwards. The front and rear ends of the bottom plate are respectively connected to the bottom ends of the two side plates. The first water inlet is opened on the left side of the top plate and the first water outlet is opened on the right side of the top plate. The two side plates and the bottom plate extend into the hollow tube body.

[0011] A further technical solution is that two first bends extend symmetrically from the front and rear sides of the top of the hollow tube, and two second bends extend symmetrically from the front and rear sides of the top plate. The second bends and the side plates enclose a snap-fit ​​groove. The top plate covers the opening at the top of the hollow tube, and the two first bends are snapped into the two corresponding snap-fit ​​grooves respectively.

[0012] A further technical solution is that a sealing gasket is provided between the first bent portion and the second bent portion.

[0013] A further technical solution is that the first water inlet is provided with a straight pipe and an elbow, the elbow being a 90° elbow, the straight pipe being horizontally arranged, the rear side of the straight pipe being connected to the front side of the elbow, and the bottom side of the elbow being connected to the interior of the hollow cover plate.

[0014] A further technical solution is that the bottom end of the hollow tube is wrapped with a cooling jacket, the front side and the rear side of the cooling jacket are respectively connected to the front side and the rear side of the hollow tube, the cooling jacket and the outer surface of the hollow tube form a cavity, a second water inlet is opened at the bottom end on the left side of the cooling jacket, and a second water outlet is opened at the rear side on the right side of the cooling jacket.

[0015] A further technical solution is that the cover plate cooling spiral machine also includes a motor, which is mounted on the top of the right side of the hollow tube. The input end of the spiral extends out of the right end of the hollow tube. The input end of the spiral is connected to the output end of the motor through a sprocket and chain transmission device, and the motor drives the spiral to rotate.

[0016] A further technical solution is that the cover plate cooling spiral machine also includes two supports, the tops of which are symmetrically located at the bottom of the left and right sides of the hollow tube body, and the bottoms of which are located on the ground.

[0017] The beneficial effects of this utility model embodiment are as follows:

[0018] (i) A cover plate cooling spiral machine includes a hollow tube body, a spiral body, and a hollow cover plate. The hollow cover plate is located on the opening at the top of the hollow tube body. The material to be cooled enters the hollow tube body through the feed inlet, and cooling water is simultaneously introduced into the hollow cover plate through the first water inlet. The cooling water flows out from the hollow cover plate to the first water outlet. After the cooling water flows inside the hollow cover plate, the spiral body rotates, and the spiral body drives the material to rotate, causing the material to be conveyed from the left side of the hollow tube body to the right side and discharged from the discharge outlet. During the rotation and conveying process, the material contacts the bottom end of the hollow cover plate. The hollow cover plate with internal cooling water cools the material. The longitudinal section of the bottom end of the hollow cover plate is an arc with the opening facing downwards, which increases the contact area between the bottom end of the hollow cover plate and the material, forming a larger heat exchange surface, enhancing the heat transfer efficiency, and improving the cooling efficiency of the device.

[0019] (II) Furthermore, two first bends extend symmetrically from the front and rear sides of the top of the hollow tube, and two second bends extend symmetrically from the front and rear sides of the top plate. The second bends and side plates enclose a locking groove. The top plate covers the opening at the top of the hollow tube, and the two side plates and bottom plate extend into the hollow tube. The two first bends are respectively locked into the two corresponding locking grooves. The design of the first and second bends, combined with the presence of the locking grooves, allows the hollow cover plate to be firmly connected to the opening at the top of the hollow tube. The first bends locking into the locking grooves of the second bends form a stable locking mechanism, ensuring that the connection between the hollow cover plate and the hollow tube is not easily loosened. This effectively prevents the cover plate from falling off or shifting during operation due to vibration or other external forces. It also allows for quick disassembly of the hollow cover plate without the need for additional tools or complex operations. (III) Furthermore, the bottom end of the hollow tube is wrapped with a cooling jacket. The front and rear sides of the cooling jacket are connected to the front and rear sides of the hollow tube, respectively. The cooling jacket and the outer surface of the hollow tube form a cavity. A second water inlet is provided at the bottom left side of the cooling jacket, and a second water outlet is provided at the rear right side of the cooling jacket. The design of the cooling jacket further absorbs and removes the heat transferred from the hollow tube by the flow of cooling water, providing additional heat exchange area, so that the cooling water can efficiently remove more heat and prevent the hollow tube from overheating.

[0028] Example:

[0029] Figure 1 This is a schematic diagram of the main structure of the cover plate cooling spiral machine of this utility model. Figure 1 As shown, a cover plate cooling spiral machine includes a hollow tube body 100, a spiral body 200, and a hollow cover plate 300. The hollow tube body 100 is a semi-frame type with an opening at the top. The left side of the hollow tube body 100 is provided with a feed inlet 101, and the right side of the hollow tube body 100 is provided with a discharge outlet 102.

[0030] like Figure 1As shown, the spiral 200 is rotatably mounted inside the hollow tube 100. For example, the cover plate cooling spiral machine also includes a motor 500, which is mounted at the top right side of the hollow tube 100. The input end of the spiral 200 extends out of the right end of the hollow tube 100, and the input end of the spiral 200 is connected to the output end of the motor 500 via a sprocket and chain drive. The motor 500 drives the spiral 200 to rotate via the sprocket and chain drive.

[0031] Figure 2 This is a side sectional view of the hollow tube body in the cover plate cooling spiral machine of this utility model. Figure 3 This is a side sectional view of the hollow cover plate in the cover plate cooling spiral machine of this utility model. Figure 4 This is a side sectional view of the hollow cover plate installation in the cover plate cooling spiral conveyor of this utility model. Figures 2-4 As shown, a hollow cover plate 300 is provided on the opening at the top of the hollow tube body 100. A first water inlet 340 is provided on the left side of the hollow cover plate 300, and a first water outlet 350 is provided on the right side of the hollow cover plate 300. The bottom end of the hollow cover plate 300 extends into the hollow tube body 100, and the longitudinal section of the bottom end of the hollow cover plate 300 is a downward-opening arc. For example, the hollow cover plate 300 includes a top plate 310, two side plates 320 and a bottom plate 330. The top ends of the two side plates 320 are respectively connected to the bottom ends of the front and rear sides of the top plate 310. The longitudinal section of the bottom plate 330 is an arc with an opening facing downwards. The front and rear ends of the bottom plate 330 are respectively connected to the bottom ends of the two side plates 320. The first water inlet 340 is opened on the left side of the top plate 310 and the first water outlet 350 is opened on the right side of the top plate 310. The two side plates 320 and the bottom plate 330 extend into the hollow tube body 100.

[0032] Figure 5 for Figure 4 A magnified view at point A. (See image below.) Figures 4-5As shown, further, two first bends 103 extend symmetrically from the front and rear sides of the top of the hollow tube 100, and two second bends 360 extend symmetrically from the front and rear sides of the top plate 310. The second bends 360 and the side plate 320 enclose a snap-fit ​​groove 370. The top plate 310 covers the opening at the top of the hollow tube 100, and the two first bends 103 are snapped into the two corresponding snap-fit ​​grooves 370 respectively. The design of the first bending part 103 and the second bending part 360, together with the presence of the snap-fit ​​groove 370, allows the hollow cover plate 300 to be firmly connected to the opening at the top of the hollow tube 100. The first bending part 103 snaps into the snap-fit ​​groove 370 of the second bending part 360, forming a stable locking mechanism. This ensures that the connection between the hollow cover plate 300 and the hollow tube 100 is not easy to loosen, effectively preventing the cover plate from falling off or shifting in position due to vibration or other external forces during operation. At the same time, it enables the hollow cover plate 300 to be quickly disassembled without the need for additional tools or complicated operations.

[0033] like Figure 5 As shown, a sealing gasket 380 is further provided between the first bend 103 and the second bend 360. The sealing gasket 380 can effectively reduce the small gap between the first bend 103 and the second bend 360, increase the sealing performance of the cover plate, and ensure that the material inside the hollow tube 100 will not leak. At the same time, during the operation of the screw conveyor, the sealing gasket 380 can also absorb a certain amount of vibration and impact, reduce the transmission of vibration caused by the rotation of the screw 200 or other mechanical factors, reduce the wear of mechanical parts, and reduce the noise of the equipment during operation.

[0034] like Figure 3 As shown, the first water inlet 340 is further provided with a straight pipe 341 and an elbow 342. The elbow 342 is a 90° bend, and the straight pipe 341 is horizontally arranged. The rear side of the straight pipe 341 connects to the front side of the elbow 342, and the bottom side of the elbow 342 connects to the interior of the hollow cover plate 300. The elbow 342 can effectively avoid excessive water flow impact or poor flow, allowing the water to flow controllably and uniformly within the hollow cover plate 300, thereby improving the reliability of the entire cooling system.

[0035] like Figures 1-2As shown, furthermore, a cooling jacket 600 is wrapped around the bottom end of the hollow tube 100. The front and rear sides of the cooling jacket 600 are connected to the front and rear sides of the hollow tube 100, respectively. The cooling jacket 600 and the outer surface of the hollow tube 100 enclose a cavity. A second water inlet 610 is provided at the bottom left side of the cooling jacket 600, and a second water outlet 620 is provided at the rear right side of the cooling jacket 600. The design of the cooling jacket 600 further absorbs and removes the heat transferred from the hollow tube 100 by the flow of cooling water, providing additional heat exchange area, so that the cooling water can efficiently remove more heat and prevent the hollow tube 100 from overheating.

[0036] Furthermore, the cover plate cooling spiral machine also includes two supports 400, the tops of which are symmetrically located at the bottom of the left and right sides of the hollow tube body 100, and the bottoms of the supports 400 are located on the ground.

[0037] In operation, this embodiment is as follows:

[0038] The material to be cooled enters the hollow tube 100 through the feed inlet 101, while cooling water is simultaneously introduced into the hollow cover plate 300 through the first inlet 340. The cooling water flows from the hollow cover plate 300 to the first outlet 350, allowing the cooling water to circulate within the hollow cover plate 300. Then, cooling water is introduced into the cooling jacket 600 through the second inlet 610, flowing from the cooling jacket 600 to the second outlet 620. After the cooling water circulates within the hollow jacket, the electric motor is activated. The machine 500 and the motor 500 drive the spiral 200 to rotate. The spiral 200 drives the material to rotate and causes the material to be conveyed from the left side to the right side inside the hollow tube 100. During the rotation and conveying process, the material contacts the bottom end of the hollow cover plate 300 and the bottom end of the hollow tube 100. Since the cooling jacket 600 wraps around the bottom end of the hollow tube 100, the hollow cover plate 300 with cooling water flowing inside and the cooling jacket 600 cool the material together. The cooled material is discharged from the outlet 102.

[0039] In this embodiment, the material contacts the bottom of the hollow cover plate 300, and the hollow cover plate 300 with internal cooling water cools the material. The longitudinal section of the bottom of the hollow cover plate 300 is an arc with an opening facing downwards, which increases the contact area between the bottom of the hollow cover plate 300 and the material, forms a larger heat exchange surface, enhances the heat transfer efficiency, and improves the cooling efficiency of the device.

[0040] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
