Description

Technical Field

[0001] This utility model relates to the field of plastic machinery technology, specifically a feeding and filtering device that is easy to move and install. Background Technology

[0002] Traditional filtration systems consist of filters and vacuum fans. Due to differing installation requirements, the filters and vacuum fans are installed separately. Furthermore, the filters are quite tall, while the vacuum fans are mounted on the ground or other platforms. This installation presents the following problems: 1. The filters are approximately 2.9 meters tall, posing significant installation challenges and space requirements that are difficult to meet in typical factory buildings; 2. The long vacuum piping required due to the installation positions of the filters and vacuum fans (filters at a high position, vacuum fans at a low position) increases installation costs.

[0003] Due to limitations in customer factory height and installation conditions, and to address these issues, a new structure needs to be designed that can greatly facilitate transportation and installation without reducing the filter area. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides a feeding and filtering device that is easy to move and install. It modifies the traditional structure, making installation and maintenance convenient and improving the installation flexibility of the entire drying system.

[0005] To achieve the above objectives, a material feeding and filtration device that is easy to move and install is designed, including a frame, filters, an electrical control box, and a vacuum fan. The device is characterized by: a vacuum fan installed at the lower part of the frame; several filters installed at the upper part of the frame; and an electrical control box installed on the side of the frame. The filters are connected to each other via one end of a vacuum pipe, and the other end of the vacuum pipe is connected to the vacuum fan. A dust collection bin is connected to the bottom of each filter.

[0006] The vacuum blower has an air inlet and an air outlet on one side, and the air inlet is connected to a vacuum pipe.

[0007] At least two filters are provided.

[0008] One end of the vacuum pipe branches into multiple paths, which are respectively connected to the lower ends of several filters and negative pressure air inlet pipes; the other end of the vacuum pipe is connected to the air inlet of the vacuum blower.

[0009] A pressure relief valve is installed at the branch point of the vacuum pipeline.

[0010] The upper end of the negative pressure air inlet pipe is connected to the material receiver.

[0011] The electrical control box is connected to a vacuum blower, several filters, and a pressure relief valve via wiring.

[0012] Compared with the prior art, this utility model provides a feeding and filtering device that is easy to move and install. It modifies the traditional structure, making installation and maintenance easier and improving the installation flexibility of the entire drying system.

[0013] This utility model integrates the filter and vacuum fan on a dedicated frame, saving on vacuum pipe material. At the same time, multiple filters are connected in parallel and are always in a negative pressure balance state. When one filter filters more dust than another, its pressure will increase and the airflow will be biased towards the other filter, which can improve the flexibility and efficiency of the feeding system.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the old feeding system had separate filters and vacuum blowers connected by pipes. This equipment was usually placed on the customer's platform, which was extremely inconvenient to install. In addition, the overall height of a filter was very high, which was limited by the height of the customer's factory.

[0022] To address these issues, a new feeding and filtration device was designed for easy mobile installation. The new feeding system's filter and vacuum fan are mounted on a single frame, and two filters are designed to reduce the overall height without compromising the filtration area, greatly facilitating transportation and installation.

[0023] like Figures 2 to 5As shown, a vacuum fan 2 is installed at the lower part of the frame 1, several filters 3 are installed at the upper part of the frame 1, and an electrical control box 6 is installed on the side of the frame 1; the filters 3 are connected to each other through one end of a vacuum pipe 5, and the other end of the vacuum pipe 5 is connected to the vacuum fan 2; a dust collection bin 4 is connected to the bottom of the filters 3.

[0024] The vacuum blower 2 has an air inlet 2-1 and an air outlet 2-2 on one side, and the air inlet 2-1 is connected to the vacuum pipe 5.

[0025] At least two filters 3 are provided.

[0026] One end of the vacuum pipe 5 branches into multiple paths, which are respectively connected to the lower ends of several filters 3 and negative pressure air inlet pipes 8; the other end of the vacuum pipe 5 is connected to the air inlet 2-1 of the vacuum fan 2.

[0027] A pressure relief valve 7 is provided at the bifurcation point of the vacuum pipe 5.

[0028] The upper end of the negative pressure air inlet pipe 8 is connected to the material receiver.

[0029] The electrical control box 6 is connected to the vacuum blower 2, several filters 3, and pressure relief valve 7 via wiring.

[0030] When the vacuum blower 2 is started, a negative pressure is formed in the feeding system, creating a pressure difference with the external atmospheric pressure. The material is sucked into the receiver through the suction pipe, and the air enters the filter 3 through the negative pressure air inlet pipe 8. The material is trapped in the hopper, and the dust-laden airflow is filtered through the filter 3. The dust is intercepted and enters the dust collection bucket 4. The clean air enters the vacuum blower 2 and is discharged through the air outlet 2-2.

[0031] Multiple filters are connected in parallel to maintain a negative pressure balance. When one filter filters more dust than another, its pressure increases and the airflow is biased towards the other filter, allowing the feeding system to work continuously and improving work efficiency.
