Description

Technical Field

[0001] The utility model relates to the technical field of material conveying equipment, in particular to a material dividing screw conveyor. Background Art

[0002] Currently, in the paper and wood-based panel industries, the capacity of individual production lines is increasing, leading to a growing demand for raw materials. In the raw material processing section, due to the limited processing capacity of a single screening device, multiple screening devices are required to meet the raw material screening needs of large-scale production lines. This often results in the need to evenly distribute large amounts of raw materials across several different screening devices.

[0003] The conventional method of material distribution is to use a multi-stage three-way funnel. The first-stage three-way funnel can achieve a one-to-two split, and the second-stage three-way funnel will continue to split the branch from the first-stage three-way funnel into two, thus finally achieving the one-to-three split. Although this material distribution mode can achieve the design intention of one-to-three, it has obvious disadvantages: first, the entire distribution mechanism uses gravity to transport the material, and its layout takes up a lot of height space and requires a larger drop to achieve; second, it is difficult for the three-way funnel to evenly distribute the material to the three different drop points.

[0004] Therefore, how to avoid the problem of the conveyor taking up too much space is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0040] The utility model aims to provide a material dividing screw conveyor, which can avoid the problem that the conveyor occupies too much space.

[0041] To achieve the above objectives, the present invention provides the following technical solutions:

[0042] See also Figures 1 to 4 , this embodiment provides a material-dividing screw conveyor, including: a silo 100, two material-dividing channels 200 and a material-dividing rotor assembly 300; the silo 100 is used to buffer and store materials to be transported, and the silo 100 is installed above the silo casing 110, and a first discharge port 120 is provided below the silo casing 110; the two material-dividing channels 200 are used to transport the materials in the silo 100 to different positions, and the two material-dividing channels 200 are respectively installed on both sides of the silo casing 110 and are connected to the silo 100; the material-dividing rotor assembly 300 is installed at the first discharge port 120, and is connected to the silo 100, and is used to transport materials downward.

[0043] like Figure 1As shown, the silo 100 in this embodiment is arranged above the silo casing 110, and its internal space is interconnected. The material to be transported will be stored inside the silo 100, and two dividing channels 200 are installed on both sides of the silo casing 110. The dividing channels 200 are connected to the inside of the silo casing 110, and the two dividing channels 200 share one silo casing 110. The dividing channels 200 can divide the material in the silo 100 in the silo casing 110 and transport it to different positions respectively. At the same time, a first discharge port 120 is provided directly below the silo casing 110, and a dividing rotor assembly 300 is provided at the first discharge port 120, which is also used to divide the material in the silo casing 110. In this way, the embodiment of the present application can realize the one-to-three transportation of materials.

[0044] Specifically, the silo 100 is installed directly above the silo casing 110, and materials can be temporarily stored inside. Two distribution channels 200 are respectively installed on both sides of the silo casing 110, and the distribution channels 200 are therefore connected to the silo 100. The two distribution channels 200 point to different positions respectively, and can transport the materials in the silo 100 to different positions. In addition, a distribution rotor assembly 300 is installed at the first discharge port 120 directly below the silo casing 110. The distribution rotor assembly 300 can transport the materials in the silo 100 downward through the first discharge port 120. In this way, the materials in the silo 100 can be transported to three different positions at the same time. The transportation of materials is only achieved by the distribution channels 200 and the distribution rotor assembly 300, which can reduce the space occupied by the conveyor.

[0045] Preferably, the distribution channel 200 includes: a conveying pipe 210, a screw shaft 230 and a first motor 240; the conveying pipe 210 is installed on the side of the silo casing 110, and the end of the conveying pipe 210 away from the silo 100 is provided with a downward-facing second discharge port 220; the screw shaft 230 is rotatably arranged inside the conveying pipe 210, connected to the silo 100, and is used to transport materials; the first motor 240 is installed at the end of the conveying pipe 210 away from the silo 100, and the first motor 240 is connected to the screw shaft 230, and is used to provide conveying power to the screw shaft 230.

[0046] like Figure 2 and Figure 3As shown, the material distribution channel 200 in this embodiment includes a conveying pipe 210, a screw shaft 230 and a first motor 240. The conveying pipe 210 is installed on the left and right sides of the silo 100 and the silo casing 110, and is connected to the interior of the silo casing 110. Of course, the cross-sectional shape of the silo 100 can be adjusted according to actual conditions, as long as it can accommodate other components and does not affect the transportation of materials; a screw shaft 230 is provided through the interior of the conveying pipe 210, one end of the screw shaft 230 extends into the interior of the silo casing 110 and is located below the silo 100, so that the screw shaft 230 can be in direct contact with the material, and the material can be transported along the screw shaft 230 through the conveying pipe 210; in this embodiment, the rotation of the screw shaft 230 is achieved by the first motor 240 arranged at the end away from the silo 100, and the movable end of the first motor 240 is fixedly connected to the screw shaft 230, and the rotation of the screw shaft 230 is driven by the rotation of the first motor 240, thereby transporting the material in the silo casing 110 outward.

[0047] In this way, the material distribution and transportation can be achieved by connecting the distribution channel 200 on the side of the silo housing 110. Compared with the existing technology of distribution and transportation by gravity, the material distribution can be controlled and the layout space occupied by the existing technology can be reduced.

[0048] Preferably, the two material distribution channels 200 are arranged in parallel, and the conveying directions of the material distribution channels 200 are both extended along the length of the conveying pipe 210 and away from the direction of the silo 100.

[0049] like Figure 3 As shown, the two material distribution channels 200 in this embodiment are arranged in parallel, and the materials are distributed and transported to the left and right sides respectively. Since the screw shaft 230 needs to extend into the interior of the silo housing 110, in order to avoid interference between the two screw shafts 230, the two material distribution channels 200 are arranged in parallel. Figure 3 As shown in FIG, the two spiral shafts 230 are respectively arranged on both sides of the silo housing 110. In this arrangement, both spiral shafts 230 can be fully extended into the silo housing 110, thereby separating and transporting the materials. This arrangement can also ensure that the materials distributed into the two distribution channels 200 are roughly the same, ensuring uniform distribution. Among them, the material transportation direction in this embodiment is away from the direction of the silo 100 and is transported along the conveying pipe 210.

[0050] Preferably, spiral blades are provided on the circumference of the spiral shaft 230 , and the spiral blades are full-leaf spiral blades, and the spiral blades are installed on the outer circumference of the spiral shaft 230 by welding.

[0051] In this embodiment, spiral blades with fixed pitch and diameter are provided on the spiral shaft 230, and the spiral blades are preferably full-leaf spiral blades, which can increase the efficiency of material distribution and transportation. In addition, to enhance the overall strength of the spiral blades, the spiral blades are connected to the spiral shaft 230 by welding. It should be noted that the pitch and diameter of the spiral blades can be set according to actual conditions and are not specifically limited herein.

[0052] Preferably, the material distribution rotor assembly 300 includes: a discharging rotor 310 and a second motor 320; the discharging rotor 310 is rotatably mounted at the first discharge port 120, and the discharging rotor 310 is arranged parallel to the spiral shaft 230, and a scraper is provided on the discharging rotor 310; the second motor 320 is installed under the silo casing 110 and connected to the discharging rotor 310, for providing power for the rotation of the discharging rotor 310.

[0053] like Figure 2 As shown, in this embodiment, a discharge rotor 310 is provided at the position of the first discharge port 120 below the silo casing 110, and a scraper is provided on the discharge rotor 310. It can be understood that the material will be distributed in the silo casing 110. In order to enable the material to be distributed to the first discharge port 120 while being transported into the distribution channel 200, a scraper is provided on the discharge rotor 310. When the discharge rotor 310 rotates, the scraper can distribute a part of the material in the silo casing 110 to the first discharge port 120; in this embodiment, the power required for the rotation of the discharge rotor 310 is provided by the second motor 320. Of course, other power devices can also be selected according to actual conditions.

[0054] Preferably, the first motor 240 and the second motor 320 are both connected to a control box, and the control box is used to perform frequency conversion and speed regulation on the motors.

[0055] It can be understood that the rotation of the rotating shaft and the unloading rotor 310 will affect the quality of the material distribution to different discharge ports. Therefore, in order to enable the material distribution screw conveyor to distribute materials evenly to different discharge ports, the first motor 240 and the second motor 320 are both connected to a control box, and the control box can perform frequency conversion and speed regulation on the motors; wherein, in order to be able to more accurately control the rotation speed of the first motor 240 and the second motor 320, pressure sensors are provided on the spiral blades and the scraper blades, which can detect the pressure of the transported materials, thereby roughly knowing the gravity of the transported materials. When the weight of the materials at the discharge ports in different directions is inconsistent, the control box will control the rotation speed of the first motor 240 or the second motor 320, so that the distribution channel 200 with heavier materials reduces the motor speed, and the distribution channel 200 with lighter materials increases the motor speed, so as to try to keep the materials output by the first discharge port 120 and the two second discharge ports 220 uniform; in this embodiment, the two first motors 240 and the one second motor 320 are independently controlled by the control box, so that the discharge of each discharge port can be guaranteed to be uniform according to the pressure sensor.

[0056] Preferably, the discharge rotor 310 is located below the middle of the two spiral shafts 230, and the distance between the axis of the discharge rotor 310 and the axis of the spiral shaft 230 is greater than the sum of the rotation radius of the spiral blade and the rotation radius of the scraper blade.

[0057] like Figure 4 As shown, the two spiral shafts 230 are arranged in parallel and at the same height, and the discharge rotor 310 is arranged at a position slightly below the two. In this way, the material can fall from the gap between the two spiral shafts 230 onto the discharge rotor 310 and then be discharged from the first discharge port 120. Since the spiral shafts 230 and the discharge rotor 310 are respectively provided with spiral blades and scrapers, in order to avoid interference between the spiral blades and the scrapers, the distance between the axis of the discharge rotor 310 and the axis of the spiral shaft 230 is greater than the sum of the rotation radius of the spiral blades and the rotation radius of the scrapers.

[0058] Preferably, the silo 100 is an inverted funnel-shaped structure as a whole, the opening cross-section of the silo 100 is square, and gradually expands in the direction approaching the silo casing 110 .

[0059] like Figure 1 As shown, it can be understood that the inverted funnel-shaped structure with a smaller opening that expands linearly downward can effectively prevent leakage of materials while accommodating more materials.

[0060] Preferably, openable viewing windows 400 are provided on the side of the silo 100 and on the end of the distribution channel 200 facing away from the silo 100 .

[0061] In addition, if Figure 1As shown, in the embodiment of the present application, openable visual windows 400 are provided on the side of the silo 100 and the end of the distribution channel 200 away from the silo 100. The visual windows 400 on the silo 100 can clearly see the remaining material inside, and the visual windows 400 at the end of the distribution channel 200 are all located above the second discharge port 220 for observing the discharge of the material.

[0062] Preferably, a protrusion is provided at the bottom of the silo housing 110 to cooperate with the discharge rotor 310 to slow down the falling of the material.

[0063] like Figure 4 As shown, in order to prevent the material from being discharged from the silo casing 110 without being controlled by the discharge rotor 310, a protrusion is provided at the bottom of the silo casing 110 that cooperates with the discharge rotor 310. In this way, the material can only be discharged through the action of the discharge rotor 310, and the discharge situation of the first discharge port 120 can be controlled, thereby ensuring that the material is discharged evenly from each discharge port.

[0064] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0065] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0066] The above is a detailed introduction to the embodiments provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the method and core concept of the present invention. It should be noted that, for those skilled in the art, without departing from the principles of the present invention, various improvements and modifications may be made to the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
