Description

Technical Field

[0001] This application relates to the field of roller mechanism technology, and in particular to a water-cooled roller machine. Background Technology

[0002] When materials are mixed, they may generate significant heat due to chemical reactions. To avoid the impact of high temperatures on the lifespan of the drum machine components, a water cooling system is usually installed on the drum machine. However, existing water cooling systems are mostly combinations of water pumps and radiators, which occupy a large space outside the drum machine, and the uniformity of water cooling driven by external water pumps is not good. Summary of the Invention

[0003] The purpose of this application is to provide a water-cooled drum machine with higher water-cooling effect.

[0004] To achieve the above objectives, this application provides a water-cooled roller mill: including an insulation cylinder, with end caps fixedly connected to both ends of the insulation cylinder, and a rolling assembly rotatably connected to the two end caps. The main body of the rolling assembly is a cylinder body, and the outer surface of the cylinder body has a propeller plate. The end caps have hollow cavities and through holes are provided on the end faces facing the insulation cylinder, suitable for connecting the cavity between the cylinder body and the insulation cylinder with the hollow cavity of the end caps. Each end cap has a pipe connection end on its outer surface, suitable for connecting to an external water pipe to form a complete cooling water circulation channel.

[0005] As a preferred embodiment, the outer side of the cylinder has several propeller plates, which are arranged equidistantly around the axis of the cylinder. Both ends of the cylinder have limiting rings, and each end of the propeller plate is fixedly connected to two limiting rings respectively. The limiting rings are also provided with convection holes that pass through both end faces to ensure normal flow of cooling water.

[0006] As a preferred embodiment, the cylinder has end tubes at both ends, which respectively cooperate with the two end caps to form a rotating pair, thereby restricting the relative degrees of freedom between the roller assembly and the insulation cylinder.

[0007] As a preferred embodiment, one end of the end tube passes through the end cap and is fixedly connected to a pulley, while the other end tube connects the inner cavity of the cylinder to the outside, allowing materials to enter and exit the cylinder.

[0008] As a preferred embodiment, the inner wall of the cylinder has a number of baffles, which are arranged equidistantly around the axis of the cylinder, making the mass distribution of the entire cylinder more uniform.

[0009] As a preferred embodiment, the two end caps are respectively the liquid inlet ring and the liquid outlet ring. The liquid inlet ring, the liquid outlet ring, and the bottom surface of the insulation cylinder are all fixedly connected to a bracket, which is used to suspend the main body of the cooling drum machine at a certain height off the ground, so as to reserve sufficient configuration space for the external pipeline structure.

[0010] As a preferred embodiment, the hollow cavity of the liquid inlet end ring is a liquid injection chamber, the bottom of the liquid inlet end ring has a first pipe connection end, and the through hole opened on the end face of the liquid inlet end ring is a liquid inlet; the hollow cavity of the liquid outlet end ring is a reflux chamber, the bottom of the liquid outlet end ring has a second pipe connection end, and the through hole opened on the end face of the liquid outlet end ring is a liquid outlet, serving as a channel for cooling water to flow through.

[0011] As a preferred embodiment, the side wall of the insulation cylinder has a heat insulation cavity, which makes the insulation cylinder form a double-layer structure with good heat insulation effect, so that the outer surface of the entire water-cooled drum machine has a suitable temperature, effectively reducing the risk of workers being burned.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By configuring a propeller plate structure outside the rotating cylinder to replace the water pump to make the cooling water flow, not only is the space occupied by the water pump outside the cylinder saved, but the cooling water can also be more evenly wrapped around the outside of the cylinder, resulting in better heat absorption uniformity and improved heat absorption effect.

[0014] (2) The design structure is simpler and more compact, with higher work efficiency and smaller space occupation. It is more convenient to use and configure and has higher work stability. Attached Figure Description

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-5The water-cooled roller mill shown includes a cylindrical insulation cylinder 1 with a horizontal axis. The side wall of the insulation cylinder 1 has an insulation cavity 101, which is hollow or filled with a gas with low thermal conductivity, such as carbon dioxide. The insulation cavity 101 creates a double-layer structure for the insulation cylinder 1, providing excellent heat insulation performance. Both ends of the insulation cylinder 1 are fixedly connected to annular end caps 2, each with a through-hole in the center. The two end caps 2 are rotatably connected to a rolling assembly 4. Specifically, the rolling assembly 4 includes... The main body is a cylindrical body 401, which has two end tubes 402 with reduced diameters at both ends. These end tubes 402 cooperate with two end caps 2 to form a rotating pair. All end caps 2 and end tubes 402 are coaxial with the cylindrical body 401. One end tube 402 passes through the end cap 2 and is fixedly connected to a pulley 3 for cooperation with an external belt drive structure. The other end tube 402 connects the inner cavity of the cylindrical body 401 to the outside, making it convenient to put materials into the cylindrical body 401 and also convenient to discharge materials from the cylindrical body 401.

[0026] The outer surface of the cylinder 401 has propeller plates 403. The propeller plates 403 have equal width and uniform pitch at all points. There are several propeller plates 403 on the outer surface of the cylinder 401, each with the same specifications and the same direction of rotation. These propeller plates 403 are equidistantly arranged around the axis of the cylinder 401. Both ends of the cylinder 401 have coaxial limiting rings 405, which protrude from the outer surface of the cylinder 401. Each end of each propeller plate 403 is fixedly connected to two limiting rings 405, effectively improving... To enhance the connection strength of the propeller plates 403, the limiting ring 405 is also provided with convection holes 406 that penetrate both end faces. The convection holes 406 are located between the ends of adjacent propeller plates 403. The inner wall of the cylinder 401 also has a deflector plate 404. The extension direction of the deflector plate 404 is parallel to the axis of the cylinder 401. There are several deflector plates 404. These deflector plates 404 are equidistantly arranged around the axis of the cylinder 401 and are used to deflect the material inside the cylinder 401 when the cylinder 401 rotates, thereby increasing the tumbling amplitude of the material inside the cylinder 401.

[0027] End cap 2 has the same annular hollow cavity, and a through hole is also provided on the end face facing the insulation cylinder 1 to connect the cavity between the cylinder body 401 and the insulation cylinder 1 with the hollow cavity of end cap 2, forming a channel for cooling water circulation. Each end cap 2 has a pipe connection end on its outer side for connecting to an external water pipe. In fact, the two end caps 2 have the same structure, but their functions are different on the water-cooled drum machine, so they are named liquid inlet end ring 210 and liquid outlet end ring 220 respectively. The liquid inlet end ring 210, the liquid outlet end ring 220 and the bottom surface of the insulation cylinder 1 are all fixedly connected to a bracket 5 to suspend the main body of the water-cooled drum machine at a certain height off the ground. The hollow cavity of the liquid inlet end ring 210 The liquid injection chamber 212 has a first pipe connection end 211 at the bottom of the liquid inlet end ring 210, and a through hole on the end face of the liquid inlet end ring 210 is the liquid inlet port 213; the hollow cavity of the liquid discharge end ring 220 is the return chamber 222, the bottom of the liquid discharge end ring 220 has a second pipe connection end 221, and a through hole on the end face of the liquid discharge end ring 220 is the liquid discharge port 223. Cooling water enters the liquid injection chamber 212 from the first pipe connection end 211 through the external pipe, then enters the cavity between the cylinder 401 and the insulation cylinder 1 through the liquid inlet port 213 and the convection hole 406, then enters the return chamber 222 through the convection hole 406 and the liquid discharge port 223, and finally returns to the external pipe through the second pipe connection end 221.

[0028] Working principle: Before operation, the material enters the cylinder 401 through the open end pipe 402. The coaxial pulley 3 drives the cylinder 401 to rotate under the drive of the external belt. The propeller plate 403 rotates synchronously, pushing the cooling water between the cylinder 401 and the insulation cylinder 1. The cooling water flows from one end of the cylinder 401 to the other end under the thrust. Therefore, the external pipe only needs to be connected to the radiator structure. There is no need to connect an additional water pump structure to ensure good heat dissipation efficiency.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
