[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0017] like Figure 1 As shown in the figure, one embodiment of this disclosure provides a main material feeding system for an environmentally friendly stone paper making machine. The main material feeding system includes a main material supply device 100, multiple feeding components 200, a material conveying pipe assembly 300, and an air extraction device 400. The main material supply device 100 includes a storage bin 110 with a discharge port 120. The multiple feeding components 200 correspond to multiple paper making machines and are used to feed material to the corresponding paper making machine. Each feeding component 200 includes a buffer bin 210 and a metering bin 220 disposed below the buffer bin 210. The buffer bin 210 and the metering bin 220 are connected by a switching valve 230. The capacity of the buffer bin 210 is smaller than the capacity of the metering bin 220. The material conveying pipe assembly 300 includes a main material conveying pipe 310 and multiple material conveying branch pipes 320 connected to the main material conveying pipe 310. Each of the multiple material conveying branch pipes 320 is correspondingly arranged with a multiple of the feeding assemblies 200. The main material conveying pipe 310 is connected to the discharge port 120, and each material conveying branch pipe 320 is connected to the buffer chamber 210 in its corresponding feeding assembly 200. An air extraction device 400 is connected to the buffer chamber 210 of each feeding assembly 200 to draw the main material from the storage silo 110 into the buffer chamber 210.

[0018] The metering chamber 220 in the feeding assembly 200 is used to supply main material to the environmentally friendly stone paper making machine below the metering chamber 220. When the main material in the metering chamber 220 is low, for example, below the preset height, the switch valve 230 is opened to replenish the main material in the buffer chamber 210 to the metering chamber 220. After the main material in the buffer chamber 210 is replenished to the metering chamber 220, the switch valve 230 is closed, and the vacuum device 400 is started to evacuate the buffer chamber 210, so that the main material in the storage chamber 110 is replenished to the buffer chamber 210 through the main conveying pipe 310 and the conveying branch pipe 320 of the conveying pipe assembly 300.

[0019] In the main material feeding system of the environmentally friendly stone paper making machine provided in this embodiment, the feeding component 200 is equipped with a buffer chamber 210 and a metering chamber 220, and a switch valve 230 is provided between the buffer chamber 210 and the metering chamber 220. The metering chamber 220 is used to supply material to the environmentally friendly stone paper making machine. The vacuum device 400 is connected to the buffer chamber 210. When material needs to be replenished, the switch valve 230 is closed, and the vacuum device 400 vacuums the buffer chamber 210 to draw the main material in the storage chamber 110 into the buffer chamber 210. The capacity of the buffer chamber 210 is smaller than the capacity of the metering chamber 220, so that the vacuum device 400 can provide sufficient suction force to the buffer chamber 210 to realize one-to-many operation.

[0020] In one embodiment, the storage silo 110 includes a first straight cylindrical section 111 and a first conical section 112 connected below the first straight cylindrical section 111, with the discharge port 120 disposed on the first conical section 112. The first conical section 112 guides the main material so that it can be smoothly discharged through the discharge port 120. In another embodiment, the first straight cylindrical section 111 can also be replaced with a cone with a gradually increasing diameter from top to bottom, thereby preventing powder from bridging and affecting the discharge.

[0021] In one embodiment, a support frame 130 is provided above the first straight cylindrical section 111, and a horn structure 140 is provided on the support frame 130 for supporting the material bag. The support frame 130 can be a circumferentially closed structure to prevent dust leakage. In one embodiment, an air suction structure can be provided on the horn structure 140 to suck air from the material bag to ensure that the material bag is flat and to prevent wrinkles from affecting the material feeding.

[0022] In one embodiment, the buffer chamber 210 includes a second straight section 211 and a second conical section 212 connected to the lower part of the second straight section 211. The material conveying branch pipe 320 and the air extraction device 400 are both connected to the second straight section 211. The material conveying branch pipe 320 is connected to the side of the second straight section 211, for example.

[0023] The metering chamber 220 includes a third straight section 221 and a third conical section 222 connected below the third straight section 221. The second conical section 212 is connected to the third straight section 221 via a switching valve 230.

[0024] The inner diameter of the second straight section 211 is smaller than the inner diameter of the third straight section 221, so as to reduce the power consumption of the air extraction device 400.

[0025] In one embodiment, the extraction device 400 includes a fan 410, a filter 420, and an extraction pipe assembly 430. The fan 410 is connected to the extraction pipe assembly 430 via the filter 420. The extraction pipe assembly 430 includes a main extraction pipe 431 and multiple extraction branch pipes 432 connected to the main extraction pipe 431. Each of the multiple extraction branch pipes 432 corresponds to a multiple feeding assembly 200. The main extraction pipe 431 is connected to the filter 420, and each extraction branch pipe 432 is connected to the second straight section 211 of the buffer chamber 210 of the corresponding feeding assembly 200, for example, to the top surface of the second straight section 211. The filter 420 filters dust from the air, thereby optimizing the production environment.

[0026] In one embodiment, the filter 420 includes a support 421, an outer cylinder 422, and a filter element 423. The outer cylinder 422 is disposed on the support 421. The filter element 423 is disposed inside the outer cylinder 422, dividing the outer cylinder 422 into a pre-filter space and a post-filter space. The main exhaust pipe 431 is connected to the outer cylinder 422 and communicates with the pre-filter space. The fan 410 is connected to the outer cylinder 422 via a connecting pipe and communicates with the post-filter space. Thus, the airflow carrying dust enters the pre-filter space, passes through the filter element 423, and enters the post-filter space, while the dust remains in the pre-filter space.

[0027] In one embodiment, a discharge cylinder 424 is included below the outer cylinder 422, and a waste discharge valve 425 is provided at the bottom end of the discharge cylinder 424. By opening the waste discharge valve 425, dust is discharged.

[0028] In one embodiment, the discharge cylinder 424 is conical, which facilitates dust discharge.

[0029] In one embodiment, a control valve 433 is provided on the extraction branch pipe 432, so that each extraction branch pipe 432 can be controlled separately.

[0030] In one embodiment, a Venturi tube is provided on some of the extraction branch pipes 432. For example, a Venturi tube is provided on the longer extraction branch pipes 432 to improve the power of the airflow in the extraction branch pipes 432 and avoid the unevenness of air pressure in different extraction branch pipes 432 due to different lengths.

[0031] In the main material feeding system of the environmentally friendly stone paper making machine provided in this embodiment, the feeding component 200 is equipped with a buffer chamber 210 and a metering chamber 220, and a switch valve 230 is provided between the buffer chamber 210 and the metering chamber 220. The metering chamber 220 is used to supply material to the environmentally friendly stone paper making machine. The vacuum device 400 is connected to the buffer chamber 210. When material needs to be replenished, the switch valve 230 is closed, and the vacuum device 400 vacuums the buffer chamber 210 to draw the main material in the storage chamber 110 into the buffer chamber 210. The capacity of the buffer chamber 210 is smaller than the capacity of the metering chamber 220, so that the vacuum device 400 can provide sufficient suction force to the buffer chamber 210 to realize one-to-many operation.

[0032] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
