Description

Technical Field

[0001] The utility model belongs to the technical field of raw material recovery, and in particular relates to a recycling material collection bin for ceiling film production. Background Art

[0002] During the production of ceiling membranes, some raw materials cannot enter the production. In order to save energy, high-pressure wind is used to send these raw materials to the upper collection bin for collection. The collection bin is a conical structure, with a cyclone separation tube connected to the upper part and a recovery bag connected to the lower part, and an air outlet is provided at the top. After the high-pressure wind carrying the raw materials enters the collection bin, the airflow will swirl and overflow upward, but this part of the airflow pressure still carries some raw materials. Due to the small volume of the raw materials, they will inevitably emerge from the top of the collection bin, which not only reduces the recovery rate of the raw materials, but also makes the surrounding environment full of dust. Utility Model Content

[0003] The purpose of the utility model is to provide a return material collection bin for ceiling film production to solve the above technical problems.

[0004] The technical solution adopted by the utility model is that the ceiling film production return material collection bin comprises a bin body, the bin body is in a conical structure, the upper part is connected to a cyclone separation pipe, the lower part is connected to a recovery bag, a return air duct is arranged in the middle of the top of the bin body, the top of the return air duct is connected to a return pipe, the return pipe is arranged obliquely, and a filter bag is tied to the return pipe outlet.

[0005] Preferably, the lower portion of the return air duct extends into the silo body and is located below the cyclone separation tube.

[0006] Preferably, at least two discharge pipes are provided at the bottom of the silo body, and valves are provided on the discharge pipes.

[0007] Preferably, the outlet of the discharge pipe is connected to a recovery bag, a weighing sensor is provided below the recovery bag, the weighing sensor is connected to a controller, the controller is connected to an alarm, and the alarm is mounted on a frame of the silo body.

[0008] Preferably, the height of the lower conical part of the silo body is twice that of the upper cylindrical part.

[0009] Compared with the prior art, the beneficial effect of the utility model is that, by setting a return air duct in the middle of the top of the aggregate bin, the top of the return air duct is connected to the return pipe, and the return pipe is set obliquely. After the high-pressure wind enters the aggregate bin from the cyclone separation pipe, it moves downward along the inner wall of the aggregate bin and then swirls. The upward wind is partially blocked by the inner wall of the top of the aggregate bin, and the raw materials fall to the bottom of the aggregate bin. Part of the wind overflows from the return air duct. Due to the inclined setting of the return pipe, the raw materials are blocked back to the aggregate bin again, preventing the raw materials from overflowing the aggregate bin with the swirling wind, solving the current problem that the raw materials are easy to emerge from the aggregate bin, the recovery rate is low and the surrounding environment is polluted. Among them, the filter bag is tied to the outlet of the return pipe. The filter bag has a larger filtering area than the filter net, which further filters the raw materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION

[0011] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0012] Example 1

[0013] like Figure 1 As shown, the recycling collection bin for ceiling film production includes a bin body 1, which is in a conical structure, connected to a cyclone separation pipe 3 at the top and a recovery bag 8 at the bottom. A return air pipe 2 is provided at the middle of the top of the bin body 1, and the top of the return air pipe 2 is connected to a return pipe 11, which is arranged obliquely, and a filter bag 4 is tied at the outlet of the return pipe 11. After the high-pressure air enters the bin body 1 from the cyclone separation pipe 3, it moves downward along the inner wall of the bin body 1 and then swirls. The upward wind is partially blocked by the inner wall at the top of the bin body 1, and the raw materials fall to the bottom of the bin body 1. Part of the wind overflows from the return air pipe 2. Since the return pipe 11 is arranged obliquely, the raw materials are blocked back to the bin body again, preventing the raw materials from overflowing the bin body 1 with the swirling wind, and solving the current problem that the raw materials are easy to emerge from the collection bin, the recovery rate is low and the surrounding environment is polluted. The filter bag 4 is tied at the outlet of the return pipe 11, and the filter bag 4 has a larger filtering area than the filter net, which further filters the raw materials.

[0014] The lower part of the return air duct 2 extends into the silo body 1 and is located below the cyclone separation tube 3. It combines with the silo body 1 to enhance the effect of raw materials falling in the silo body 1, and concentrates wind force to move toward the return pipe 11, thereby enhancing the reaction force of the return pipe 11 on the raw materials it carries, and blocking the raw materials back to the silo body 1.

[0015] At least two discharge pipes 6 are provided at the bottom of the silo body 1 , and valves 7 are provided on the discharge pipes 6 . The two discharge pipes 6 are used for staggered or simultaneous discharge to prevent the silo body 1 from being filled up.

[0016] The outlet of the discharge pipe 6 is connected to the recovery bag 8, a weighing sensor 10 is provided below the recovery bag 8, the weighing sensor 10 is connected to the controller, the controller is connected to the alarm 9, and the alarm 9 is installed on the frame of the silo body 1. The weighing sensor 10 is used to monitor whether the recovery bag 8 is full, and the controller is used to set a threshold. When a certain threshold is reached, the alarm 9 sounds an alarm and provides a replacement for the recovery bag 8.

[0017] Furthermore, the height of the lower conical part of the silo body 1 is twice that of the upper cylindrical part, providing sufficient space for wind to swirl instead of blowing the raw materials flying around, which is conducive to continuously intercepting the falling materials during the wind swirl, and part of the wind is blown out from the return air duct.

[0018] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
