Description

Technical Field

[0001] This utility model relates to the field of coating dispersion machines, and in particular to a wood oil dispersion machine. Background Technology

[0002] The coating disperser is a component of wood oil production equipment. In order to ensure the performance of wood oil, it is necessary to mix coloring coatings, extender coatings, defoamers, mildew inhibitors, wetting agents, thickeners, etc. evenly. Therefore, the coating disperser is required to shear and impact the materials in the mixing cylinder to achieve the purpose of refining, dispersing, dissolving and mixing the materials.

[0003] In the production process of preservative-treated wood oil, both the mildew inhibitor and the thickener need to be diluted before being added to the mixing drum. This requires simultaneous addition and stirring, with the principle being to add them as dilute as possible and as slowly as possible. The main purpose of this operation is to reduce the formation of gel lumps due to uneven dispersion of the liquid additives during the addition process.

[0004] Existing dispersers use a dispersing device to stir various raw materials in a mixing drum to achieve thorough mixing. The stirring method of this type of disperser is relatively simple. The stirring disc of the dispersing device is located in the lower middle part of the mixing drum and can generate strong shear force, which makes the raw materials in contact with the stirring disc stirred and dispersed. However, the additives added at the top cannot be dispersed in time due to insufficient flowability, which can easily lead to the formation of gel lumps and affect the quality of the final product. Summary of the Invention

[0005] The purpose of this invention is to provide a wood oil disperser. By rotating a switch with a concave-convex structure, the disperser can be opened or closed. A dispersion hole for additives to flow out is provided on the side wall of the dispersion tube. The additives will be dispersed longitudinally in the mixing cylinder along the dispersion hole on the dispersion tube. With the stirring of the mixing disc, the additives will be evenly dispersed in the raw materials, avoiding the phenomenon of excessive additives in some places causing gel lumps.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A wood oil disperser includes a mixing cylinder and a stirring disc suspended in the mixing cylinder by a support frame. The stirring disc is fixedly provided with a dispersion component. The dispersion component includes a dispersion tube with an additive supply unit connected to the upper end and sealed at the lower end, and a switch element with a concave-convex structure arranged along the circumferential direction and coaxially nested inside the dispersion tube.

[0008] The side wall of the dispersion tube is provided with a dispersion hole for the additive to flow out. The dispersion hole can be opened or closed by rotating the switch with the concave-convex structure.

[0009] With the above solution, when additives need to be added, the mixing cylinder and the additive supply unit can be connected by rotating the switch with the concave-convex structure, and the additive pumping mechanism can be started. The additives will be added to each longitudinal section of the raw material along the length of the dispersion component. When the stirring plate rotates, the raw material and additives in the mixing cylinder can be mixed evenly to avoid the formation of gel lumps.

[0010] The present invention further provides that the dispersing holes are arranged in rows along the axial direction of the dispersing tube on the side wall of the dispersing tube, and the number of rows of dispersing holes can be set according to the amount of additive added.

[0011] The above technical solutions can ensure increased production efficiency without the formation of agglomerates.

[0012] The present invention further includes a configuration in which the stirring plate and the dispersing component are connected to the same fixing member, and the fixing member is installed on the support frame via a displacement mechanism.

[0013] The above method can fix the relative position between the stirring plate and the dispersing component.

[0014] This utility model further specifies that the diameter of the stirring plate is D1, the diameter of the mixing cylinder is D2, and the distance from the bottom of the stirring plate to the bottom of the mixing cylinder is H2, wherein the relationship between D2 and D1 is as follows:

[0015] D2 = (2.8 to 4)D1;

[0016] The relationship between H2 and D1 is as follows:

[0017] H2 = (0.5 to 1)D1.

[0018] Through the above technical solutions, an annular chamber effect is easily formed inside the mixing drum. The so-called annular chamber effect means that when viewed from above, a small part of the mixing disc is still visible. This annular chamber effect helps to disperse the raw materials inside the mixing drum under the action of shear force.

[0019] The present invention further includes an adjustment plate fixed to the upper end of the switch component, the adjustment plate being fixed to the connecting seat via a pin hole, and a rotating handle being provided on the upper part of the adjustment plate to drive the switch component to rotate by external force.

[0020] The above technical solutions can quickly locate the position of a switch with a concave-convex structure based on the position of the pin hole, and clearly determine whether the dispersion hole is open or closed.

[0021] The present invention further includes a feature whereby the dispersion tube is riveted to a fixing member via a connecting seat.

[0022] The above technical solutions facilitate the cleaning and replacement of the dispersion tubes.

[0023] The present invention further provides that the dispersion tube is composed of multiple short tubes coaxially and sealed together.

[0024] The above technical solutions allow for the assembly of dispersion tubes of different lengths as needed. This expands the interoperability of dispersion tubes across different models and saves on the cost of replacing damaged dispersion tubes.

[0025] The present invention further includes a shifting mechanism comprising a drive motor, a screw, and a guide rod, wherein a fixed component, which is fixedly connected to a stirring plate and a dispersing assembly, moves up and down along the guide rod under the drive of the drive motor.

[0026] By adopting the above technical solution, the beneficial effects of the present invention are:

[0027] This invention opens or closes by rotating a switch with a concave-convex structure. A dispersion hole for additive outflow is provided on the side wall of the dispersion tube. The additive will be dispersed longitudinally in the mixing cylinder along the dispersion hole on the dispersion tube, satisfying different mixing depths. The additive is uniformly dispersed longitudinally in the raw materials. With the stirring of the stirring plate, the additive will be evenly dispersed in the raw materials, effectively avoiding the phenomenon of excessive additive in local areas causing gel lumps, thus improving product quality.

[0035] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0036] The following is for reference Figures 1 to 6 This embodiment will be described.

[0037] like Figures 1 to 6 The wood oil disperser shown includes a mixing cylinder 2 and a stirring disc 3 suspended in the mixing cylinder 2 by a support frame 1. Dispersion components 4 are fixedly arranged on both sides of the stirring disc 3. The dispersion components 4 include a dispersion tube 11 with an upper end connected to an additive supply unit and a lower end sealed, and a switch element with a circumferentially arranged concave-convex structure 12 coaxially nested inside the dispersion tube 11. The side wall of the dispersion tube 11 has dispersion holes for additive outflow. Rotating the switch element 12 with the concave-convex structure opens or closes the dispersion holes. When additives need to be added, rotating the switch element 12 with the concave-convex structure connects the mixing cylinder 2 to the additive supply unit, activating the additive pumping mechanism. The additive is added along the length of the dispersion component 4 to various longitudinal sections of the raw material. When the stirring disc 3 rotates, the raw material and additives in the mixing cylinder 2 are mixed evenly, preventing the formation of gel lumps. The dispersion holes are arranged in rows along the axial direction of the dispersion tube 11 on its side wall; in this embodiment, two sets of dispersion holes are provided. The number of dispersion holes is primarily determined by the amount of additive added and production efficiency. Longitudinal distribution of the dispersion holes ensures uniform dispersion of the additive across all longitudinal sections. Increasing the number of dispersion hole rows improves production efficiency without causing agglomeration. The mixing disc 3 and the dispersion assembly 4 are connected to the same fixing member 5, which is mounted on the support frame 1 via a shifting mechanism 15. This fixes the relative positions of the mixing disc 3 and the dispersion assembly 4.

[0038] In this embodiment, the wood oil disperser is a single-shaft disperser, and the mixing drum is circular. The dispersion effect is optimal when the following relationship exists in this embodiment:

[0039] D2 = 2.8D1;

[0040] H1=D1;

[0041] H2=0.5D1;

[0042] Dispersed long component degree = depth of mixing pan + H2.

[0043] Where D1 is the diameter of the mixing disc, D2 is the diameter of the mixing cylinder, H1 is the loading height, and H2 is the distance between the bottom of the mixing disc and the bottom of the mixing cylinder. In this case, an annular chamber effect is easily formed inside the mixing cylinder 2. The so-called annular chamber effect means that when viewed from above the mixing cylinder 2, a small part of the mixing disc 3 is still visible. This annular chamber effect is beneficial for dispersing the raw materials inside the mixing cylinder 2 under the action of shear force.

[0044] An adjusting plate 14 is fixed to the upper end of the switch component. The adjusting plate 14 is fixed to the connecting seat 6 through a pin hole. A rotating handle 10 is provided on the upper part of the adjusting plate 14, which is driven to rotate the switch component by external force. When the handle is rotated, the position of the switch component 12 with concave and convex structure can be quickly located according to the position of the pin hole, so as to determine whether the dispersion hole is open or closed.

[0045] The dispersion tube 11 is riveted to the fixing part 5 via the connecting seat 6, which facilitates the cleaning and replacement of the dispersion tube 11.

[0046] The dispersion tube 11 is made of multiple short tubes coaxially sealed together. The short tubes can be made into standard lengths and assembled into dispersion tubes 11 of different lengths as needed. This not only expands the interoperability of dispersion tubes 11 between different models, but also saves the cost of replacing some short tubes after they are damaged.

[0047] The shifting mechanism 15 includes a drive motor 7, a guide rod 8, and a screw 9. The fixing member 5, which is fixedly connected to the mixing plate 3 and the dispersing component 4, moves up and down along the guide rod under the drive of the drive motor 7. This can ensure that the additive is uniformly dispersed longitudinally in the raw materials when the mixing depth is different.

[0048] When additives need to be added, the first step is to activate the shifting mechanism 15 to move the mixing plate 3 and the dispersing component 4 to a suitable position. The second step is to connect the additive supply unit and the dispersing tube through the additive inlet. The third step is to activate the additive supply unit and simultaneously adjust the switch 12 with its concave-convex structure by rotating the handle, so that the mixing cylinder, dispersing tube, and additive supply unit are in a connected state. Under the pressure of the additive supply unit, the additive will be evenly dispersed along the length of the dispersing tube to each longitudinal section of the raw material, avoiding the formation of gel lumps.
