Abstract
Description
Technical Field
[0001] This utility model particularly relates to an anti-clogging flow guiding structure used in the production of varnish. Background Technology
[0002] As an important coating additive, varnish primarily enhances the gloss, abrasion resistance, and scratch resistance of products. The production process of varnish typically involves adding granular solid raw materials (such as various resin particles) into a reaction vessel or mixing tank to dissolve and mix with a liquid solvent.
[0003] Existing technologies use simple guide channels or feeding hoppers to introduce granular raw materials into the reaction equipment. However, due to the high coefficient of friction and poor flowability of the granular raw materials, bridging is very likely to occur in the narrow parts of the guide channel during the feeding process, forming a stable arched structure above the outlet, which hinders the fall of subsequent materials and causes feeding interruption. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an anti-clogging flow guiding structure for use in varnish production.
[0005] To solve the aforementioned technical problems, this utility model adopts the following technical solution:
[0006] A clog-preventing flow guiding structure for use in varnish production includes:
[0007] The sleeve has a flow channel formed inside;
[0008] A feeding hopper, located at the upper end of the sleeve, is used to feed granular raw materials into the guide channel;
[0009] A cross-shaped guide frame is provided at the upper edge of the sleeve to receive the granular raw materials from the feeding hopper and perform initial dispersion.
[0010] Multiple guide columns are rotatably disposed on the inner side wall of the sleeve and located below the cross-shaped guide frame; spiral grooves are formed on the surface of the guide columns.
[0011] A drive assembly, connected to each of the guide columns, is used to drive the guide columns to rotate; wherein, the particulate material, after being initially dispersed by the cross-shaped guide frame, falls into the guide channel, and the drive assembly drives the guide columns to rotate, thereby moving the particulate material through the spiral groove.
[0012] Furthermore, the cross-shaped flow guide includes a first flow guide rod and a second flow guide rod disposed on the upper edge of the sleeve. The first flow guide rod and the second flow guide rod are arranged perpendicularly, and the outer surfaces of the first flow guide rod and the second flow guide rod are provided with stirring teeth.
[0013] Furthermore, the driving component includes:
[0014] A rotary motor, which is mounted on the outer wall of the sleeve;
[0015] A drive shaft is rotatably mounted on the outer wall of a sleeve between two adjacent guide columns and is driven by the rotary motor. The upper end of the drive shaft is connected to the upper end of one of the guide columns via a first drive belt. The lower end of the drive shaft is connected to the lower end of another adjacent guide column via a second drive belt. When the rotary motor is working, it drives the drive shaft to rotate, thereby driving the two adjacent guide columns to rotate via the first and second drive belts.
[0016] Furthermore, a first fixing plate and a second fixing plate are spaced apart on the outer wall of the sleeve, and the drive shaft passes through and is rotatably mounted on the first fixing plate and the second fixing plate.
[0017] Furthermore, the guide column is a frustum-shaped structure that is narrow at the top and wide at the bottom, with spiral grooves on its surface extending from the top to the bottom.
[0018] Furthermore, an upper positioning platform and a lower positioning platform are provided at intervals on the inner wall of the sleeve, and the two ends of the guide column are rotatably mounted on the upper positioning platform and the lower positioning platform, respectively.
[0019] The beneficial effects of this utility model are:
[0020] This invention constructs a highly efficient active arch-breaking system through a dual dispersion design of a cross-shaped guide frame and rotating guide columns. The cross-shaped guide frame first intercepts and segments the falling granular raw materials, effectively disrupting the initially formed arch structure. Subsequently, multiple guide columns driven by the drive assembly rotate synchronously, and the spiral grooves on their surfaces exert continuous shearing, grinding, and axial pushing effects on the material. This completely dismantles the stable bridges formed between particles due to friction and mechanical meshing, forcing the material downwards. This mechanism fundamentally prevents blockages and ensures the continuity and stability of production. Attached Figure Description

[0030] A clog-preventing flow guiding structure for use in varnish production includes:
[0031] Sleeve 1, with a flow channel 11 formed inside it;
[0032] Feeding hopper 2, which is located at the upper end of the sleeve 1, is used to feed granular raw materials into the guide channel 11;
[0033] A cross-shaped guide frame is provided at the upper edge of the sleeve 1 to receive the granular raw materials from the feeding hopper 2 and perform initial dispersion.
[0034] Multiple guide columns 4 are rotatably disposed on the inner side wall of the sleeve 1 and located below the cross-shaped guide frame; a spiral groove 41 is formed on the surface of the guide column 4.
[0035] A drive assembly is connected to each of the guide columns 4 and is used to drive the guide columns 4 to rotate; wherein, the particulate raw material after being initially dispersed by the cross-shaped guide frame falls into the guide channel 11, and the drive assembly drives the guide column 4 to rotate, thereby moving the particulate raw material through the spiral groove 41.
[0036] Furthermore, the cross-shaped flow guide includes a first flow guide rod 31 and a second flow guide rod 32 disposed on the upper edge of the sleeve 1. The first flow guide rod 31 and the second flow guide rod 32 are arranged vertically, and the outer surfaces of the first flow guide rod 31 and the second flow guide rod 32 are provided with stirring teeth 33.
[0037] Furthermore, the driving component includes:
[0038] A rotary motor is mounted on the outer wall of the sleeve 1;
[0039] A drive shaft 52 is rotatably mounted on the outer wall of a sleeve 1 between two adjacent guide columns 4 and is driven by the rotary motor. The upper end of the drive shaft 52 is connected to the upper end of one of the guide columns 4 via a first drive belt 53. The lower end of the drive shaft 52 is connected to the lower end of another adjacent guide column 4 via a second drive belt 54. When the rotary motor is working, it drives the drive shaft 52 to rotate, which in turn drives the two adjacent guide columns 4 to rotate via the first drive belt 53 and the second drive belt 54.
[0040] Furthermore, a first fixing plate 55 and a second fixing plate 56 are spaced apart on the outer wall of the sleeve 1, and the transmission shaft 52 passes through and is rotatably mounted on the first fixing plate 55 and the second fixing plate 56.
[0041] Furthermore, the cross-section of the guide column 4 is a frustum-shaped structure that is narrow at the top and wide at the bottom, and the spiral groove 41 on its surface extends from the top to the bottom.
[0042] Furthermore, an upper positioning platform 12 and a lower positioning platform 13 are provided on the inner wall of the sleeve 1 at intervals, and the two ends of the guide column 4 are respectively rotatably disposed on the upper positioning platform 12 and the lower positioning platform 13.
[0043] The working principle of this utility model is as follows:
[0044] like Figure 1-3 As shown, the anti-clogging guide structure includes a sleeve 1, a feeding hopper 2, a cross-shaped guide frame, a guide column 4, and a drive assembly.
[0045] A flow channel 11 is formed inside the sleeve 1, and a feeding hopper 2 is welded to the upper end. The cross-shaped flow guide frame is formed by the perpendicular intersection of the first flow guide rod 31 and the second flow guide rod 32, and is welded to the upper edge of the sleeve 1. The outer surfaces of the two rods are evenly distributed with stirring teeth 33. When the granular raw material is fed into the feeding hopper 2, it is first intercepted and divided by the cross-shaped flow guide frame. Its perpendicular intersection structure can effectively crush the initial material arch that is easy to form during the feeding process, and prevent the core cause of bridging from the source. At the same time, the stirring teeth 33 evenly distributed on the surface of the flow guide rod further enhance this crushing effect, making it impossible for the material to maintain a stable bridging structure. The crushed material is forced to disperse into multiple fine streams under the guidance of the stirring teeth, which significantly increases the fluidity, thereby avoiding secondary bridging that may be caused by concentrated falling at the inlet of the sleeve 1.
[0046] Six guide columns 4 are circumferentially distributed on the inner wall of the sleeve 1, forming a frustum shape that is narrower at the top and wider at the bottom. Spiral grooves 41 are formed on the surface of each guide column 4, and both ends are mounted to the upper positioning platform 12 and the lower positioning platform 13 respectively via bearings. This design effectively overcomes the bridging phenomenon that easily occurs in the guide channel 11 for particulate raw materials. Specifically, the multiple guide columns 4 circumferentially distributed on the inner side of the sleeve 1 adopt a frustum-shaped structure that is narrower at the top and wider at the bottom. Their inclined sides can effectively disrupt the initial stable arch that particles attempt to form, eliminating the mechanical support conditions required for bridging. Simultaneously, the spiral grooves 41 on the surface of the guide columns 4 generate continuous shearing and conveying action on the material during rotation, promptly cutting off any formed small arches and providing a forced downward axial force through spiral propulsion, ensuring the continuity of material flow and fundamentally avoiding material suspension and blockage. In addition, the precise rotational support of the two ends of the guide column 4 by the bearings and the upper and lower positioning platforms ensures the smooth operation of all guide columns 4, so that the above-mentioned anti-bridging effect can be continuously and stably exerted.
[0047] In the drive assembly, the rotary motor is fixed to the outer wall of the sleeve 1; the drive shaft 52 is rotatably mounted on the outer wall of the sleeve 1 via the first fixed plate 55 and the second fixed plate 56 arranged vertically; the upper end of the drive shaft 52 is connected to the upper end of the guide column 4a via the first drive belt 53, and the lower end is connected to the lower end of the guide column 4b via the second drive belt 54; when the rotary motor drives the drive shaft to rotate, the guide columns 4a and 4b are simultaneously driven to rotate via the first drive belt 53 and the second drive belt 54.
[0048] During operation, after the granular raw material is fed into the feeding hopper 2, it is first intercepted and divided by the cross-shaped guide frame. Its vertical cross structure and surface stirring teeth can effectively destroy the initial arching tendency of the material, preventing bridging from the source. After the initial dispersion, the material falls into the guide channel 11. At this time, the rotary motor starts, driving the guide columns 4a and 4b to rotate synchronously through the drive shaft 52, the first drive belt 53 and the second drive belt 54, thereby linking the rotation of the guide column 4. The rotating guide column 4 generates multi-dimensional shearing force and axial pushing force on the material through its surface spiral groove 41: the edge of the spiral groove 41 continuously cuts the small material arch structure that may be formed, destroying the mechanical balance between particles; at the same time, the inclined surface of the spiral groove 41 generates a downward component force, continuously conveying the material downward and preventing the material from stagnating in the channel. The frustum-shaped guide column 4, with its narrow top and wide bottom structure, further expands the dispersion area and works in conjunction with the spiral groove 41 to form a three-dimensional arch-breaking network, ensuring that the material flows through the guide channel 11 in a uniform state, fundamentally solving the blockage problem caused by bridging of particulate raw materials during the varnish production process.
[0049] This invention constructs a highly efficient active arch-breaking system through a dual dispersion design of a cross-shaped guide frame and rotating guide columns 4. The cross-shaped guide frame first intercepts and segments the falling granular raw materials, effectively destroying the initially formed arch structure. Subsequently, multiple guide columns 4 driven by the drive component rotate synchronously, and the spiral grooves 41 on their surfaces exert continuous shearing, grinding, and axial pushing effects on the material, which can completely dismantle the stable bridges formed between particles due to friction and mechanical meshing, and force the material to be conveyed downwards. This mechanism fundamentally eliminates the occurrence of blockages, ensuring the continuity and stability of production.
