Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a continuous spiral water-cooled conveyor. Background Technology

[0002] In industrial production fields such as lithium battery materials and chemical raw materials, materials often require rapid and uniform cooling after processing. Currently, existing equipment in the industry generally suffers from the following technical deficiencies in practical applications, making it difficult to meet the demands of modern industrial production for efficient, precise, and low-energy-consumption cooling. Firstly, traditional spiral coolers only have a single cooling channel inside the spiral blades or main shaft, or only a single-layer cooling jacket outside the conveying cavity. The flow path of the cooling medium is short and the contact area with the material is small, which means that the material can only achieve surface cooling during the conveying process, resulting in low internal temperature cooling efficiency and difficulty in achieving rapid and uniform cooling of the material. Secondly, some traditional cooling equipment occupies a large area, increasing the cost and difficulty of production layout, as well as the initial investment and operating costs.

[0003] Therefore, it is necessary to develop a continuous cooling conveying equipment with a small footprint and high cooling efficiency to solve the above problems. Utility Model Content

[0004] To address the above problems, this utility model proposes a continuous spiral water-cooled conveyor, and the technical solution used is as follows: A continuous spiral water-cooled conveyor includes a cooling outer casing, a material conveying plate, a spiral shaft, a water conveying shaft, a power system, a water outlet system, and a water inlet system. The cooling outer casing is provided with a material inlet and a material outlet. The cooling outer casing has at least one conveying space, and each conveying space is provided with a material conveying plate, which divides its conveying space into a material conveying space and an external cooling space. Each material conveying space is provided with at least one spiral shaft, which is driven to rotate by the power system. The spiral shaft has an internal cooling space inside, and the water conveying shaft is set inside the internal cooling space and fixedly connected to the spiral shaft; the water conveying shaft is hollow inside, and one end of it is provided with a connecting pipe 1 that communicates with the internal cooling space and a connecting pipe 2 that communicates with the inside of the water conveying shaft, and the other end is provided with a connecting pipe 3 that communicates with the inside of the water conveying shaft and the internal cooling space. The water inlet system includes a main water inlet pipe, and an outer water inlet pipe and an inner water inlet pipe connected to the main water inlet pipe; the outer water inlet pipe is connected to the outer cooling space, and the inner water inlet pipe is connected to a connecting pipe. The water outlet system includes a main water outlet pipe, and an outer water outlet pipe and an inner water outlet pipe connected to the main water outlet pipe; the outer water outlet pipe is connected to the outer cooling space, and the inner water outlet pipe is connected to a connecting pipe.

[0005] Furthermore, it also includes a rotary joint; the rotary joint includes a rotating shaft and a housing; the housing is fixed by an external fixing rod, the rotating shaft is sealed and rotatably installed inside the housing and fixedly installed on a spiral shaft; the rotating shaft is provided with an inner connecting water inlet pipe communicating with a connecting pipe one, and an inner connecting water outlet pipe communicating with a connecting pipe two; the inner wall of the housing is provided with an annular transition cavity one and an annular transition cavity two corresponding to the positions of the inner connecting water inlet pipe and the inner connecting water outlet pipe respectively; the housing is provided with an outer connecting water inlet pipe communicating with the inner water inlet pipe corresponding to an annular transition cavity one, and an outer connecting water outlet pipe communicating with the inner water outlet pipe corresponding to an annular transition cavity two.

[0006] Furthermore, the cooling outer casing is provided with an exhaust port that communicates with the material transport space.

[0007] Furthermore, the internal cooling space is spiral-shaped.

[0008] Furthermore, the external cooling space is provided with several baffles that are not connected to the top.

[0009] Furthermore, the external cooling space is provided with several support plates at intervals; the support plates are installed in a completely enclosed manner and have through holes.

[0010] Furthermore, a drain pipe is connected and installed in connection with the external cooling space.

[0011] Furthermore, the bottom of the cooling outer box is provided with a guide rail, which drives the sliding motion, and the slider of the guide rail is provided with a positioning pin.

[0012] Furthermore, the main outlet pipe and the main inlet pipe are connected to an external circulation system.

[0013] Furthermore, when the number of conveying space layers is greater than a certain value, the material transport spaces of adjacent conveying spaces are connected vertically at one end.

[0014] Because this utility model adopts the above-described technical solution, it has the following advantages: 1. This utility model adopts a method of simultaneous internal and external cooling. Cooling water circulates in the cooling cavity inside the spiral shaft, cooling the material from the inside out. Cooling water also flows in the space between the material conveying plate and the cooling outer box, cooling the material from the outside in, thus expanding the cooling area and ensuring that the material is cooled evenly in all directions while being conveyed and moved, effectively improving cooling efficiency. 2. By adjusting the rotational speed of the screw shaft, this utility model can precisely control the material conveying speed and cooling time, while adjusting the cooling water flow rate, thereby ensuring the accuracy and consistency of the cooling curve of each batch of material, and maximizing the consistency of the quality of each batch of material. 3. This utility model can reduce the floor space occupied by setting up multi-layer transportation space, effectively freeing up workshop space, avoiding the compression of other production facilities layout due to excessive equipment footprint, and reducing costs.

[0037] like Figures 11-13 As shown, spiral blades are fixedly installed inside the spiral shaft 3, making the inner cooling space Ⅲ spiral-shaped; the inner shaft 4 of the water conveying system is hollow, and one end of it connected to the rotary joint 8 is provided with a connecting pipe 401 and a connecting pipe 402. The connecting pipe 401 is connected to the inner cooling space Ⅲ, and the connecting pipe 402 is connected to the inside of the water conveying shaft 4; the other end of the water conveying shaft 4 is provided with a connecting pipe 403, and the two ends of the connecting pipe 403 are connected to the inside of the water conveying shaft 4 and the inner cooling space Ⅲ, respectively; the cooling water flowing into the rotary joint 8 enters the inner cooling space Ⅲ from the connecting pipe 401, moves along the inner cooling space Ⅲ to the other end, enters the inside of the water conveying shaft 4 from the connecting pipe 403, moves along the water conveying shaft 4 to one end of the rotary joint 8, and then flows into the rotary joint 8 from the connecting pipe 402, thus cooling the material from the inside out.

[0038] like Figure 14As shown, the rotary joint 8 includes a rotating shaft 801 and a housing 807; the housing 807 is fixed by an external fixing rod, and the rotating shaft 801 is sealed and rotatably installed inside the housing 807 and fixedly installed on the spiral shaft 3; the rotating shaft 801 is provided with an inner connecting water inlet pipe 803 and an inner connecting water outlet pipe 804, the inner connecting water inlet pipe 803 is connected to the first connecting pipe 401, and the inner connecting water outlet pipe 804 is connected to the second connecting pipe 402; the inner wall of the housing 807 has openings respectively connected to...

Cooling water enters the first connecting pipe 401 through the inner water inlet pipe of the water inlet system 7, the outer water inlet pipe 805, the first annular transition cavity 802a and the inner water inlet pipe 803. Cooling water flowing out of the second connecting pipe 402 enters the outer connecting water outlet pipe 806 through the inner water outlet pipe 804 and the second annular transition cavity 802b, and flows into the inner water outlet pipe of the water outlet system 6.

[0039] This embodiment uses a two-layer conveying space, with each layer of material transport space II equipped with two spiral shafts 3, as an example for specific explanation.

[0040] like Figures 6-10 As shown, the inlet 101 and outlet 102 are located at the same end of the cooling outer box 1, and the connection between the two material transport spaces II is located at the other end; the two spiral shafts 3 of the same layer are arranged side by side and rotate in opposite directions; the material enters the upper material transport space II from the inlet 101, is driven by the upper spiral shaft 3 to be transported to the other end and enters the lower material transport space II through the connection, and is then driven by the lower spiral shaft 3 to be transported to the outlet 102.

[0041] like Figure 5As shown, the pipeline arrangement at the rotary joint 8 is illustrated by taking the inner outlet pipe 603 and inner inlet pipe 703 used by the rotary joint 8 on one of the spiral shafts 3 as an example. One end of the inner outlet pipe 603 is connected to the corresponding outer outlet pipe 806 of the rotary joint 8, and the other end is connected to the main outlet pipe 601. One end of the inner inlet pipe 703 is connected to the corresponding outer inlet pipe 805 of the rotary joint 8, and the other end is connected to the main inlet pipe 701. The housings 807 of the two rotary joints 8 in the same conveying space are connected and fixed relative to each other by an outer fixing rod.

[0042] like Figures 6-7 and Figures 15-16 As shown, to ensure the flow efficiency of cooling water in the external cooling space I, the external cooling space I of each layer of the conveying space is divided into several external cooling sub-spaces, each of which is independent. In this embodiment, each layer of external cooling space I is divided into two parts. The pipeline layout is illustrated by taking the external water pipe 602 and the external water inlet pipe 702 used in one of the external cooling sub-spaces as an example. The external water inlet pipe 702 is located in the lower left corner of the external cooling sub-space and is connected to the main water inlet pipe 701. The external water pipe 602 is located in the upper right corner of the external cooling sub-space and is connected to the main water outlet pipe 601. Cooling water flows from the external water inlet pipe 702 to the external water pipe 601, cooling the material from the outside to the inside.

[0043] As a specific implementation of this embodiment, a plurality of baffles 12 and support plates 13 are provided at intervals in the external cooling space I. The baffles 12 and support plates 13 are fixedly installed inside the cooling water tank 1. The top of the baffles 12 is not connected to the top, while the support plates 13 are installed in a completely closed manner and have through holes, so that when the water flow injected by the external water inlet pipe moves, it can cross the baffles 12 from bottom to top and pass through the through holes of the support plates 13, thereby improving the cooling water circulation efficiency.

[0044] like Figure 2 , Figure 4 , Figure 7 and Figure 15 As shown, a drain pipe 9 connected to the external cooling space I is installed on the cooling outer box 1.

[0045] like Figure 4 As shown, in a specific implementation of this embodiment, the power system 5 includes a motor 501 and a transmission mechanism 502. The motor 501 drives the screw shaft 3 to rotate through the transmission mechanism 502. The transmission mechanism 502 can be a transmission wheel, a transmission chain, or a transmission gear.

[0046] like Figures 1-3As shown, the bottom of the cooling outer box 1 is provided with a guide rail 10, which drives the sliding mechanism. The slider of the guide rail is provided with a positioning pin 11 for positioning. The guide rail 10 can be an electric guide rail or a regular guide rail, which is manually pushed. When cooling is required, the guide rail moves the cooling outer box 1 to the working location, and the positioning pin 11 is inserted into the corresponding hole for positioning, and then the work can begin. When maintenance is required, the positioning pin 11 is pulled out and the cooling outer box 1 is pulled out for maintenance.

[0047] The main outlet pipe 601 and the main inlet pipe 701 are connected to an external circulation system for cooling water circulation. The circulation system is an existing technology and will not be described in detail here.

[0048] Temperature sensors are installed on both the feed inlet 101 and the discharge outlet 102 to monitor the material temperature. When the temperature change is not up to standard, the material movement speed can be controlled by adjusting the rotation speed of the screw shaft 3, thereby achieving the effect of controlling the material temperature.

[0049] The exhaust port 103 is connected to the material transport space II, which is suitable for the need for material protection and can effectively control the generation of condensate on the inner and outer walls.
