Description

Technical Field

[0001] The utility model relates to the field of waste paper treatment equipment, especially a material separator. Background Art

[0002] When the production line produces cardboard at high speed, a large amount of scraps will be generated. These scraps are broken by a shredding blower and then recycled. After the shredding blower breaks these scraps, a large amount of dust is generated. Therefore, the dust needs to be treated before processing these waste papers to prevent the dust from floating into the air and polluting the air. For example, the Chinese patent with the publication number CN216631992U discloses a new type of negative pressure dust removal system, including a plate separator and a dust removal device. In the utility model, materials such as waste paper containing dust are transported to the separator body through a pipeline. The exhaust fan sucks air into the separator body through an air duct. The waste paper and other materials are blocked by a partition net, and all the dust brought from the production line is sucked into the dust removal device through the air duct. The waste paper and other materials fall into the feeding port of the baler under the action of gravity due to the blocking of the partition net and the negative pressure state, and are compressed and baled by the baler. The dust enters the body and is filtered by a filter bag. The clean air is discharged to the outside through the air outlet. When the dust on the filter bag accumulates too much, the dust falls into the dust briquetting machine, and the dust briquetting machine presses the dust into a briquette state for recycling. This device can separate the dust on waste paper and other waste materials from the waste paper, and compress and bale the waste paper and the dust respectively, which is convenient for cleaning and recycling. However, this kind of negative pressure dust removal system uses the negative pressure principle to push gas or dust into the dust collector or filter, so as to achieve the effect of dust removal and air purification. If the air damper is opened too large, it will cause the gas flow rate to be too large, which will instead affect the air suction effect of the fan. Therefore, the air suction efficiency of the fan will decrease. This has an adverse impact on industrial production, not only causing the product quality to decline, but also increasing energy consumption. Content of the Utility Model

Detailed Embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] Please refer to Figure 1-6As shown, the material separator of the present utility model is used to be installed on waste paper treatment equipment. In the prior art, in order to facilitate the transportation and storage of waste paper, waste paper in the scattered environment is transported to a packing device by a conveying device for compressing the waste paper. However, a certain amount of dust will be generated when the traditional belt conveying device transfers waste paper and diffuses into the air. In order to avoid the diffusion of dust into the air, the waste paper is now transported in a pipeline. The waste paper moves in the pipeline driven by the air flow in the pipeline. It is ensured that the dust generated during the transfer of the waste paper is taken away together with the waste paper. A dust removal system is provided at the water outlet of the pipeline conveying to treat the dust in the pipeline. Since the paper outlet of the pipeline conveying needs to be connected in a through manner with the feeding port of the packing device 02 to ensure that the waste paper can enter the packing device 02 for compressing and packing the waste paper, a collecting bin 01 is provided above the waste paper feeding port of the packing device 02 (as Figure 1 shown). The paper outlet of the pipeline conveying and the dust inlet of the dust removal device are both connected in a through manner with the bin 01. And in order to take away the dust floating in the bin 01, the dust removal device adopts a negative pressure method to take away the dust. In order to prevent the air (the air outside the bin 01) in the packing device 02 from entering the bin 01 and affecting the working efficiency of the dust suction device, a material separator is provided between the bin 01 and the packing device 02, so that the waste paper in the bin 01 can smoothly enter the packing device 02 and at the same time prevent the packing device 02 (the air outside the bin 01) from entering the bin 01 and affecting the working efficiency of the dust suction device.

[0025] Please refer to Figures 2-3 As shown, the material separator includes a cylindrical sealing pipe 03. The upper and lower ends of the sealing pipe 03 are symmetrically provided with a waste paper feeding pipe 04 and a waste paper discharging pipe 05. The waste paper feeding pipe 04 is connected in a through manner with the bin 01. The waste paper discharging pipe 05 is connected in a through manner with the waste paper feeding port of the packing device 02. A carrying roller 06 for carrying waste paper from the waste paper feeding pipe 04 to the waste paper discharging pipe 05 is rotatably installed in the sealing pipe 03, and the carrying roller 06 is rotatably and sealingly connected with the inner wall of the sealing pipe 03.

[0026] After the waste paper in the bin 01 enters the sealing pipe 03 from the waste paper feeding pipe 04, the carrying roller 06 moves the waste paper towards the waste paper discharging pipe 05. Since the carrying roller 06 is in a sealed state with the inner wall of the sealing pipe 03 during rotation, air will not enter the bin 01 from the gap between the carrying roller 06 and the inside of the sealing pipe 03. Thus, it is avoided that the air flow in the bin 01 is too large, preventing the waste paper in the bin 01 from always floating and unable to fall into the waste paper feeding pipe 04, and at the same time improving the working efficiency of the dust removal device.

[0027] Please refer to Figure 3As shown, the carrying roller 06 includes a rotating shaft 07 horizontally arranged in the sealing tube 03. Both ends of the rotating shaft 07 are equipped with bearing seats 08. The two bearing seats 08 are fixedly installed on both sides of the sealing tube 03 through fasteners and are located outside the sealing tube 03. One end of the rotating shaft 07 is fixedly connected to a reduction motor 09. The reduction motor 09 of the present application is fixedly installed on the sealing tube 03. The rotating shaft 07 is driven by the reduction motor 09 to rotate on the sealing tube 03. Other motors or other existing technologies can also be used to act on the rotating shaft 07 to make it rotate around the bearing seat 08.

[0028] The rotating shaft 07 is provided with a receiving groove 12 for carrying waste paper. A sealing strip 13 is fixedly installed on the outer circumferential surface of the rotating shaft 07 through fasteners. A connecting shaft 10 is integrally formed on the rotating shaft 07. The connecting shaft 10 is coaxially arranged with the rotating shaft 07 and is located inside the sealing tube 03. A number of baffles 11 are evenly distributed on the connecting shaft 10. The receiving groove 12 is located between two adjacent baffles 11. One side of the baffle 11 is fixedly connected to the connecting shaft 10 by welding. A sealing strip 13 is fixedly installed at the outer edge of each baffle 11 through fasteners. The outer surface of the sealing strip 13 abuts against the inner wall of the sealing tube 03. Both ends of the sealing strip 13 abut against the outer surface of the connecting shaft 10. The sealing strip 13 fills the gap between the baffle 11 and the inner wall of the sealing tube 03, thereby preventing air from passing through the gap between the outer edge of the baffle 11 and the inner wall of the sealing tube 03 and entering the bin 01.

[0029] Mounting holes 14 are provided at the side edges of the baffle 11 and the edges of the sealing strip 13 (as Figure 4 shown). During assembly, the sealing strip 13 is stacked on the baffle 11. Fasteners pass through the mounting holes 14 to fixedly connect the baffle 11 and the sealing strip 13.

[0030] Please refer to Figures 5-6 shown. Another fixed connection method between the sealing strip 13 and the baffle 11. An installation groove is provided on the baffle 11. The installation groove and the connecting shaft 10 are located on both sides of the baffle 11. Mounting holes 14 are provided at the side edges of the baffle 11 and the edges of the sealing strip 13. The mounting holes 14 on the side of the baffle 11 are perpendicular and communicate with the installation groove. The sealing strip 13 is provided with an installation part adapted to the installation groove. The installation groove is rectangular or dovetail-shaped. The dovetail-shaped groove is preferably used. Since the carrying roller 06 is rolling. Since the outer edge of the sealing strip 13 abuts against the inner wall of the sealing tube 03. Thus, a frictional force is generated between the sealing strip 13 and the inner wall of the sealing tube 03. Through the setting of the dovetail groove, the frictional force is dispersed to the side wall of the receiving groove 12 and the fasteners, thereby slowing down the deformation of the mounting holes 14 on the sealing strip 13, and thus improving the service life of the sealing strip 13. During assembly, the installation part on the sealing strip 13 is inserted into the installation groove (as Figure 6As shown in the figure, the fastener passes through the mounting hole 14 to fixedly connect the baffle 11 and the sealing strip 13.

[0031] In order to further improve the sealing performance between the carrying roller 06 and the inner wall of the sealing tube 03, receiving holes 15 adapted to the carrying roller 06 are provided on both sides of the sealing tube 03. The receiving holes 15 are located inside the sealing tube 03 and extend outside the sealing tube 03, and both ends of the carrying roller 06 are located inside the receiving holes 15. Since the receiving holes 15 form a complete circle, the sealing strips 13 on each baffle 11 of the carrying roller 06 abut against the side wall and the bottom of the receiving groove 12, and are in a sealed state whether the carrying roller 06 is in a stopped or rotating state.

[0032] In order to prevent waste paper from entering between the sealing strip 13 and the inner wall of the sealing tube 03 and affecting the sealing performance, a waste outlet 16 communicating with the sealing tube 03 is provided at one end of the waste paper feed pipe 04, and a waste inlet 17 is provided at the other end. The diameter of the waste inlet 17 gradually decreases to the diameter of the waste outlet 16. A flange 18 is fixedly installed at the waste inlet 17 by welding. The waste paper feed pipe 04 is fixedly connected to the silo 01 through the flange 18, enabling the waste paper feed pipe 04 to be fixedly connected to any silo 01. Since the waste paper discharge pipe 05 has the same structure as the waste paper feed pipe 04, the waste paper discharge pipe 05 can be connected to any type of external packing equipment 02. At the same time, the width of the waste outlet 16 along the axial direction of the carrying roller 06 is smaller than the axial length of the carrying roller 06, and the width of the waste outlet 16 along the radial direction of the carrying roller 06 is smaller than the diameter of the carrying roller 06. Thus, there is a certain buffer space between the waste inlet 17 and the receiving hole 15. When waste paper enters the receiving groove 12 on the surface of the carrying roller 06 from the waste inlet 17, a part of the waste paper accumulates in the buffer space due to the existence of the buffer space, thereby preventing waste paper from entering between the sealing strip 13 and the inner wall of the sealing tube 03.

[0033] It should be noted that the waste paper discharge pipe 05 and the waste paper feed pipe 04 have the same structure and are symmetrically arranged on the sealing tube 03. Therefore, the waste inlets 17 and the waste outlets 16 on the waste paper discharge pipe 05 are exactly opposite to the waste inlets 17 and the waste outlets 16 on the waste paper feed pipe 04 (as shown in Figure 3 、 5 ).

[0034] When the present utility model is in use, waste paper enters the receiving groove 12 on the carrying roller 06 inside the sealing tube 03 through the waste paper feed pipe 04, and then the carrying roller 06 is driven to rotate inside the sealing tube 03 by the reduction motor 09. The waste paper in the receiving groove 12 is rotated towards the waste paper discharge pipe 05. Since the sealing strip 13 is provided at the outer edge of the baffle 11 on the carrying roller 06, air outside the silo 01 cannot enter the silo 01, thereby improving the working efficiency of the dust collection equipment.

[0035] It should be noted that, for the sake of clear description, the fastener described in this application is any one of screws, bolts, and screws.

If this specific posture changes, then the directional indications will also change accordingly.

[0037] The above embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
