[0002] The cotton collector is a rock wool production equipment, which is used to absorb the rock wool filaments thrown out by the centrifuge at high speed into felt on the mesh plate of the cotton collector. The structure of the cotton collector is disclosed in the patent "A New 6-meter Drum Cotton Collector" (Publication No.: CN103553318A), which mainly includes a frame, a cotton collecting box and a drum. The cotton collecting box is composed of two approximately triangular faces (two side faces) and a rectangular face (top face) on the cotton collector. The two triangular faces are completely symmetrical, one side is fixed to the front curtain by bolts, and the other triangular side is fixed to the rectangle by bolts. Each side is made up of several parts with cavities fixed and spliced ​​by bolts. Because the rock wool will be sprayed with glue at the centrifuge during the fiberization process of the centrifuge to cooperate with the subsequent process, and the glue is a thermosetting glue. When the temperature of the cotton collecting box is high, the glue will be cured at high temperature, and the rock wool fibers will be adhered to the side wall of the cotton collecting box, affecting the wind flow, causing uneven cotton distribution on the mesh plate, affecting the uniformity of the cotton felt, and thus affecting the quality of the product.

[0026] Example 1, a cotton collector with water-cooled wall

[0027] like Figure 1As shown, it includes a water-cooled wall inner wall 1, an outer wall 2, and a water pipe interface 3. A cavity 4 is formed between the water-cooled wall inner wall 1 and the outer wall 2. The water pipe interface 3 is connected to the outer wall 2, and cooling water is introduced into the cavity 4. As a typical embodiment, the edge of the outer wall 2 is connected to the water-cooled wall inner wall 1 by welding or bending. In order to avoid bulging of the middle position under water pressure, the water-cooled wall inner wall 1 and the outer wall 2 are fixed by welding around the punching hole 5. The contact area of ​​the water-cooled wall inner wall 1 and the outer wall 2 formed in this way is large, the connection strength is high, the problem of connection point breakage caused by water pressure is avoided, and the service life is long.

[0028] The outer wall 2 is made of 304 stainless steel to reduce the problem of rust and leakage.

[0029] In this embodiment, the thickness of the outer wall 2 is 4 mm.

[0030] The punching holes are evenly arranged on the inner wall and the outer wall of the water-cooled wall. As a typical embodiment, the center distance between adjacent punching holes is about 200 mm.

[0031] Example 2, a cotton collector with water-cooled wall

[0032] As another embodiment, Figure 2 As shown, the water-cooled wall inner wall 1 and outer wall 2 are connected by a plurality of connection columns 6 arranged at intervals. The connection columns can be made of metal and are respectively welded to the water-cooled wall inner wall 1 and the outer wall 2, so that the outer wall 2 is fixed to the outside of the water-cooled wall inner wall 1. The cavity between the water-cooled wall inner wall 1 and the outer wall 2 forms a cooling water passage, which can also achieve a good cooling effect. However, its disadvantage is that the outer wall 2 is very thin and the connection strength with the connection column is not high. Long-term water pressure can easily cause the welding point to break and leak.

[0033] Embodiment 3, cotton collecting machine

[0034] like Figure 3-4 As shown, the wall of the cotton collecting box adopts the water-cooled wall of the cotton collecting machine provided in Example 1, and the water-cooled wall is distributed on the top surface and the side surface of the cotton collecting box. Figure 1 The water-cooled wall shown is Figure 3 Cross section of the top of the cotton collecting box.

[0035] As a typical embodiment, there are two water pipe interfaces 3 located in the same cross-section, which are located at the edge respectively and connected to the water inlet pipe or the water outlet pipe at the same time. There are four water pipe joints located on the same cotton collecting box wall, the lower one is connected to the water inlet pipe, and the upper one is connected to the water outlet pipe. A connection method of lower water inlet and upper water outlet is adopted to ensure that the cooling water fills the entire cavity. When in use, a lower water pipe joint and an upper water pipe joint diagonally thereto are used, and the other two water pipe joints are reserved.

[0036] As a further improvement, the water pipe joint is connected to a metal hose for water supply.

[0037] The edge of the inner wall 1 of the water-cooled wall is bent outward, and the adjacent inner walls 1 of the water-cooled wall are connected by bolts at the bends to form independent water-cooled walls. Each water-cooled wall uses a separate water inlet and return and is equipped with a valve, which can ensure that when a side wall leaks, the water inlet of the side wall can be closed separately for maintenance without affecting the use of other side walls. The circulating water is connected to the chiller to ensure that the water temperature is reduced to achieve a cooling effect. At the same time, the cooling water uses pure water to prevent high temperature from generating water rust to block the pipeline.

[0038] like Figure 3 As shown, a cotton chopped cotton adding port 8 is arranged on the water-cooled wall on the top surface of the cotton collecting box 7, and the cotton chopped cotton of unqualified products is re-crushed and re-laid from the cotton chopped cotton adding port to form new products. A maintenance port 9 is also arranged to be able to open and close to observe the cotton distribution situation inside the cotton collecting chamber, so as to facilitate the observation of the flow state and the cleaning of the side wall of the cotton collecting chamber.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
