Technical Field

[0001] This invention relates to the field of material distribution equipment technology, specifically to a layered slurry proportional material distribution equipment. Background Technology

[0002] Paint, traditionally known as varnish in China, is a type of coating applied to the surface of an object to be protected or decorated, forming a continuous, firmly adhering film. It is typically a viscous liquid made primarily of resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, formulated with organic solvents or water. During paint production, raw materials are prepared into slurries of varying densities. After preparation, these slurries need to be mixed in specific proportions before further processing. However, due to the different densities of the slurries, stratification can occur during transport. Large quantities of slurries of different densities stratifying make it difficult to control the output in the same proportions, affecting subsequent production processes, reducing efficiency, and impacting paint quality. Summary of the Invention

[0006] Optionally, it also includes A sealing element is disposed on the material distribution plate, and one side of the sealing element abuts against the inner wall of the material distribution cylinder; A support ring is disposed on one of the multiple material distribution plates.

[0007] Optionally, the hopper has a first cylinder, a second cylinder, and a transition section. The first cylinder and the second cylinder are both cylindrical. The diameter of the first cylinder is larger than the diameter of the second cylinder. The transition section is used to connect the first cylinder and the second cylinder. The first cylinder, the transition section, and the second cylinder are connected sequentially from top to bottom.

[0008] Optionally, the transition portion is a frustum, the upper diameter of the frustum is larger than the lower diameter of the frustum, the upper end of the frustum is connected to the first cylinder, and the lower end of the frustum is connected to the second cylinder.

[0009] Optionally, it also includes A guide block is disposed inside the second cylinder. The inner wall of the guide block abuts against the distribution cylinder, and the outer wall of the guide block abuts against the hopper. The upper end of the guide block has a guide slope, and the lowest point of the guide slope is located at the feed inlet.

[0010] Optionally, the guide block is a split structure, and there are multiple guide blocks. Two guide blocks form a group, the lowest points of the two guide slopes of a group of guide blocks abut against each other, and the ends of a group of guide blocks that are far apart from each other abut against one end of another group of guide blocks.

[0011] Optionally, the feed inlets are distributed obliquely on the side wall of the distribution cylinder, and the openings of the feed inlets increase in size from top to bottom.

[0012] Optionally, the feed inlet has a first opening and a second opening, the first opening being at the same height as the first cylinder and the transition section, and the second opening being at the same height as the second cylinder.

[0013] Optionally, it also includes A discharge cylinder is provided at the bottom of the second cylinder, and the discharge port is connected to the discharge cylinder. The lower end of the discharge cylinder is conical. The discharge pipe is connected to the discharge cylinder.

[0014] The working principle and beneficial effects of this invention are as follows: In this invention, to address the problem in related technologies where it is inconvenient to control the proportional discharge of large quantities of slurry of different densities after stratification, a distribution cylinder is installed inside the silo. Distribution plates on the rotating shaft divide the silo into multiple equally sized receiving chambers, with at least four distribution plates, ensuring at least one receiving chamber separates the inlet and outlet. The receiving chambers have equal volumes, facilitating control of the discharge rate through the outlet. As the rotating shaft drives the multiple distribution plates to rotate, the slurry in the silo can enter one of the receiving chambers through the inlet. Because the outlet and inlet are separated by the distance of one receiving chamber, a situation where one receiving chamber is simultaneously connected to both the inlet and outlet is avoided, thus facilitating control of the amount of slurry entering each receiving chamber. Different densities of slurry naturally stratify upon entering the silo. As the distribution plate rotates, they simultaneously enter the receiving silo through the inlet. By controlling the feed rate of different densities within the silo, the stratified slurry can be discharged proportionally, allowing large quantities of slurry of varying densities to be discharged in the same quantitative proportion according to production needs. This facilitates the simultaneous entry of different densities of slurry into the next production process. During the distribution process, the rotating shaft remains at a low speed to ensure that each receiving silo receives slurry of different densities evenly when connected to the inlet. The proportional discharge rate of stratified slurry can be controlled by adjusting the shaft speed. Increasing the shaft speed increases the number of times each receiving silo connects to the inlet within the same time frame, resulting in a corresponding increase in the amount of slurry discharged through the outlet. Furthermore, increasing the number of distribution plates, thus increasing the number of receiving silos, and simultaneously increasing the number of inlets and outlets, can also control the amount of slurry entering the receiving silos. When the number of receiving silos is sufficiently large... It can also achieve the premixing effect of layered slurry during quantitative and proportional discharge. For every four additional material distribution plates, one additional inlet and one additional outlet are required. During the arrangement, the distance between adjacent outlets and inlets should be one storage bin to facilitate the calculation of the discharge amount based on the rotation speed of the shaft.

[0015] The working principle of this invention is as follows: First, according to production needs, different slurries are quantitatively added into the silo. Due to their density differences, the slurries naturally separate into layers, with the denser slurry located at the bottom of the silo and the less dense slurry at the top. The bottom of the inlet is flush with the bottom of the silo, while the top is higher than the height of all the slurries in the silo. As the rotating shaft drives the distribution plate to rotate, the layered slurries simultaneously enter the receiving silo through the inlet. When the receiving silo rotates to the outlet position, the corresponding slurry is discharged through the outlet, thus completing the simultaneous discharge of the layered slurries. The operation is simple and easy to control. Attached Figure Description

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Reference Figures 1-5 As the first embodiment of the present invention, a layered slurry proportional distribution device is proposed, including a silo 1 for holding slurries of different densities; a distribution cylinder 2 is disposed inside the silo 1, the axis of the distribution cylinder 2 coincides with the axis of the silo 1, and the side wall of the distribution cylinder 2 has a feed inlet 201; a rotating shaft 3 is rotatably disposed inside the distribution cylinder 2; at least four distribution plates 4 are provided, and multiple distribution plates 4 are circumferentially spaced on the rotating shaft 3, and the distribution plates 4 are used to divide the distribution cylinder 2 into multiple independent receiving chambers 401; a discharge port 202 is disposed at the bottom of the distribution cylinder 2, and at least one receiving chamber 401 is distributed between the discharge port 202 and the feed inlet 201.

[0022] In this embodiment, to address the problem in related technologies where it is inconvenient to control the proportional discharge of large quantities of slurry of different densities after stratification, a distribution cylinder 2 is installed inside the silo 1. Distribution plates 4 on the rotating shaft 3 divide the silo 1 into multiple equally sized receiving chambers 401. There are at least four distribution plates 4, ensuring that at least one receiving chamber 401 separates the inlet 201 from the outlet 202. The receiving chambers 401 have equal volumes, facilitating control of the discharge amount through the outlet 202. During the rotation of the multiple distribution plates 4 by the rotating shaft 3, the slurry in the silo 1 can enter one of the receiving chambers 401 through the inlet 201. Since the outlet 202 and the inlet 201 are separated by a receiving chamber 401, a situation where one receiving chamber 401 is simultaneously connected to both the inlet 201 and the outlet 202 is avoided, thus facilitating control of the amount of slurry entering each receiving chamber 401. Different densities of slurry enter silo 1 and naturally stratify. As the distribution plate 4 rotates, they simultaneously enter the receiving silo 401 through the inlet 201. By controlling the feed rate of different densities of slurry in silo 1, the proportional discharge of stratified slurry can be achieved. This allows a large quantity of slurry of different densities to be discharged quantitatively in the same proportion according to production needs, facilitating the simultaneous entry of slurry of different densities into the next production process. During the distribution process, the rotating shaft 3 remains at a low speed to ensure that when each receiving silo 401 is connected to the inlet 201, slurry of different densities enters the receiving silo 401 evenly. The proportional discharge rate of stratified slurry can be controlled by controlling the rotation speed of the rotating shaft 3. Increasing the rotation speed of the rotating shaft 3 increases the number of times each receiving silo connects to the inlet within the same time period, resulting in a corresponding increase in the amount of slurry discharged through the outlet 202. Based on this, the number of distribution plates 4 is increased, thereby increasing the number of receiving chambers 401. Simultaneously, the number of inlet ports 201 and outlet ports 202 is also increased, which can control the amount of slurry entering the receiving chambers 401. When the number of receiving chambers 401 is sufficient, it is also possible to achieve the premixing effect of stratified slurry during quantitative proportional discharge. For every four additional distribution plates 4, one additional inlet port 201 and one additional outlet port 202 are required. During the arrangement, adjacent outlet ports 202 and inlet ports 201 are spaced one receiving chamber 401 apart to facilitate the calculation of the proportional discharge amount based on the rotational speed of the shaft 3.

[0023] Specifically, firstly, according to production needs, different slurries are quantitatively added into silo 1. The different slurries will naturally stratify due to their density differences, with the denser slurry located at the bottom of silo 1 and the less dense slurry at the top. The lower end of the inlet 201 is flush with the bottom of silo 1, while the upper end of the inlet 201 is higher than the height of all the slurries in silo 1. As the rotating shaft 3 drives the distribution plate 4 to rotate, the stratified slurries can simultaneously enter the receiving silo 401 through the inlet 201. When the receiving silo 401 rotates to the outlet 202 position, the corresponding slurry is discharged through the outlet 202, thus completing the simultaneous discharge of the stratified slurries. The operation is simple and easy to control.

[0024] Furthermore, the material distribution plate 4 has eight parts, with two inlets 201 and two outlets 202, and the two inlets 201 and two outlets 202 are distributed sequentially and alternately on the material distribution cylinder 2.

[0025] This embodiment discloses the arrangement of the discharge port 202 and the inlet port 201 when the number of material distribution plates 4 is eight, such as... Figure 2 As shown. By increasing the number of material distribution plates 4, the number of inlet ports 201 and outlet ports 202 also increases accordingly, enabling the two inlet ports 201 and the two outlet ports 202 to feed and discharge simultaneously, thereby improving the speed and efficiency of the same-phase discharge of the stratified slurry.

[0026] Furthermore, it also includes a sealing element 5, which is disposed on the material distribution plate 4, with one side of the sealing element 5 abutting against the inner wall of the material distribution cylinder 2; and a support ring 6 is disposed on multiple material distribution plates 4.

[0027] In this embodiment, a sealing element 5 is also provided on the distribution plate 4. The sealing element 5 further improves the sealing performance of the receiving chamber 401, making the multiple receiving chambers 401 independent of each other and preventing material from mixing between adjacent receiving chambers 401. This makes the proportion of stratified slurry discharged more accurate. Slurry can only enter the receiving chamber 401 through the inlet 201 and exit the receiving chamber 401 through the outlet 202. This prevents the situation where material already in one receiving chamber 401 mixes with material in other receiving chambers 401 during feeding, which would make it difficult to control the discharge ratio.

[0028] Furthermore, the hopper 1 has a first cylinder 101, a second cylinder 102, and a transition section 103. Both the first cylinder 101 and the second cylinder 102 are cylindrical. The diameter of the first cylinder 101 is larger than the diameter of the second cylinder 102. The transition section 103 is used to connect the first cylinder 101 and the second cylinder 102. The first cylinder 101, the transition section 103, and the second cylinder 102 are connected sequentially from top to bottom.

[0029] In this embodiment, the hopper 1 is composed of a first cylindrical body 101 and a second cylindrical body 102 with different diameters, and they are connected together by a transition portion 103, such as Figure 1 As shown. The denser slurry is located at the lower end of silo 1, while the less dense material is located at the upper end. The denser slurry typically has poorer flowability. When the diameter of the first cylinder 101 is larger than the diameter of the second cylinder 102, the slurry in the upper layer can exert a squeezing effect on the denser slurry in the lower layer, improving the flowability of the lower slurry and facilitating its entry into the receiving silo 401 through the feed inlet 201.

[0030] Furthermore, the transition section 103 is a frustum, with the upper diameter of the frustum being larger than the lower diameter of the frustum. The upper end of the frustum is connected to the first cylinder 101, and the lower end of the frustum is connected to the second cylinder 102.

[0031] In this embodiment, the transition part 103 is conical in shape, which serves as both a transition and a guide. The transition surface is smooth, and the slurry is not easy to stick to the wall. There are no dead corners at the connection between the transition part 103 and the first cylinder 101 and the second cylinder 102, making cleaning convenient.

[0032] Furthermore, it also includes a guide block 7, which is disposed inside the second cylinder 102. The inner wall of the guide block 7 abuts against the distribution cylinder 2, and the outer wall of the guide block 7 abuts against the hopper 1. The upper end of the guide block 7 has a guide slope 701, and the lowest point of the guide slope 701 is located at the feed inlet 201.

[0033] In this embodiment, a flow guide block 7 is provided inside the second cylinder 102, such as... Figure 3 and Figure 4 As shown, the lowest point of the guide slope 701 is located at the opening of the feed inlet 201, so that under the action of the guide block 7, all the slurry in the hopper 1 can enter the receiving hopper 401. At the same time, through the guidance of the guide block 7, the slurry at the bottom has better fluidity, which further facilitates the flow of the slurry to the receiving hopper 401.

[0034] Furthermore, the guide block 7 has a split structure, with multiple guide blocks 7. Two guide blocks 7 form a group, and the lowest points of the two guide slopes 701 of a group of guide blocks 7 abut against each other. The ends of a group of guide blocks 7 that are far apart from each other abut against one end of another group of guide blocks 7.

[0035] In this embodiment, to facilitate the assembly of the flow guide block 7 into the hopper 1, the flow guide block 7 adopts a split structure, such as... Figure 4 As shown. The number of guide blocks 7 is twice the number of feed inlets 201, and two guide blocks 7 work together to guide the flow of slurry through one feed inlet 201. All the guide blocks 7 abut against each other, forming a ring, so that the slurry is all above the guide blocks 7.

[0036] Furthermore, the feed inlets 201 are inclinedly distributed on the side wall of the distribution cylinder 2, and the openings of the feed inlets 201 increase in size from top to bottom.

[0037] In this embodiment, since the slurry with higher density has poorer fluidity than the slurry with lower density, the shape of the inlet 201 is set to be smaller at the top and larger at the bottom, such as... Figure 4 As shown. The difference in the size of the feed inlet 201 compensates for the difference in slurry flowability.

[0038] Furthermore, the feed inlet 201 has a first opening 2011 and a second opening 2012. The first opening 2011 is at the same height as the first cylinder 101 and the transition section 103, and the second opening 2012 is at the same height as the second cylinder 102.

[0039] In this embodiment, the feed inlet 201 consists of two parts: a first opening 2011 and a second opening 2012. The first opening 2011 is mainly for slurry with low density to pass through, and the second opening 2012 is mainly for slurry with high density to pass through. Since the height of the slurry gradually decreases during the discharge process, the shapes of the first opening 2011 and the second opening 2012 are still gradually increasing from top to bottom.

[0040] Furthermore, it also includes a discharge cylinder 8, which is located at the bottom of the second cylinder 102. The discharge port 202 is connected to the discharge cylinder 8, and the lower end of the discharge cylinder 8 is conical. The discharge pipe 9 is connected to the discharge cylinder 8.

[0041] In this embodiment, the slurry discharged through the discharge port 202 will enter the discharge cylinder 8. The discharge cylinder 8 is conical in shape and also serves as a guide, so that the stratified slurry can enter the next process after passing through the discharge cylinder 8.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
