Description

Technical Field

[0001] This utility model relates to the technical field of rosin resin production equipment, and in particular to a rosin resin production melting device. Background Technology

[0002] Rosin resin is a light-colored, highly polymerized (dimerized) resin with a high softening point, high viscosity, and better oxidation resistance. It is completely resistant to crystallization in liquid or solution. Its many uses include paints, desiccants, synthetic resins, automotive inks, floor tiles, rubber compounds, fluxes, solder pastes, and various adhesives and protective coatings.

[0003] Rosin resin requires heating and dissolving processes during production. However, most dissolving equipment melts rosin resin inside a melting tank. During melting, the liquid rosin resin adheres to the unmelted rosin resin, causing the liquid to affect the heating effect of the unmelted rosin resin, resulting in slow dissolving efficiency and slow work efficiency.

[0004] Therefore, a melting device for liquid separation during the dissolution of rosin resin has been developed. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] 1. In this utility model, the raw material is heated and melted after being fed into the upper rotating chamber inside the melting box.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] Please see Figures 1-4 This utility model provides a rosin resin production melting device, including a melting box 1. A controller 3 is installed on the outside of the melting box 1. The externally purchased controller 3 facilitates the operation of the electrical components in the device, making its working efficiency simpler. A support plate 2 is installed at the bottom of the melting box 1 to raise the bottom and facilitate the material feeding work at the bottom. The melting box 1 has a cylindrical upper rotating cavity 12 and a lower rotating cavity 13 at its upper and lower ends. A middle filter screen 14 is provided at the connection between the upper rotating cavity 12 and the lower rotating cavity 13. The melted liquid in the upper rotating cavity 12 can be fed into the lower rotating cavity 13 through the middle filter screen 14, thereby realizing solid-liquid separation. This design allows for faster melting, prevents liquid from affecting the melting progress of solid, and improves practicality. Heating tanks 15 are provided on the inner walls of the upper rotating cavity 12 and the lower rotating cavity 13, and heating elements 16 are installed inside the heating tanks 15. The heating elements 16 are used to heat and dissolve the rosin resin inside. Heating elements 16 are also provided in the lower rotating cavity 13 so that the liquid can be heated after entering the cavity, allowing the incompletely dissolved raw materials to continue to dissolve and preventing solidification. The lower rotating cavity 13 has a through bottom drain 110 at the bottom end, and a solenoid valve 111 is installed inside the bottom drain 110 to drain the dissolved rosin resin liquid.

[0026] Preferably, a rotating shaft 17 is rotatably installed inside both the upper rotating cavity 12 and the lower rotating cavity 13. Several stirring rods 18 are installed on the outside of each rotating shaft 17. The rotating shaft 17 passes through the outside of the melting tank 1 and is equipped with a transmission wheel 112. The transmission wheels 112 are connected to each other by a belt 113. A second motor 5 is installed on the other side of the melting tank 1 and is connected to the rotating shaft 17. When the second motor 5 drives one rotating shaft 17 to rotate, the upper and lower rotating shafts 17 can be driven to rotate simultaneously under the transmission of the transmission wheel 112 and the belt 113. This causes the stirring rods 18 to rotate, which in turn drives the rosin resin inside the upper rotating cavity 12 and the lower rotating cavity 13 to rotate. This makes the rosin resin heat more evenly and dissolve better. A scraper 19 is installed on the outside of the stirring rod 18 and contacts the inner wall of the upper rotating cavity 12 and the lower rotating cavity 13. This prevents the raw material from adhering to the inner wall under the rotation of the scraper 19 and prevents the middle filter screen 14 from being blocked, thus making the feeding rate faster.

[0027] Please see Figure 4 A feeding box 4 is installed on one side of the top of the melting box 1. A funnel-shaped discharge port 42 is provided at the bottom of the feeding box 4, which passes through the upper rotating cavity 12. A through-feed port 41 is provided on one side of the top of the feeding box 4. A filter screen 43 is provided at the lower end of the feeding box 4. A transmission rod 44 is rotatably installed inside the feeding box 4. A first motor 45 is installed at the top of the feeding box 4 and connected to the transmission rod 44. A crushing blade 46 is installed at the bottom of the transmission rod 44. The rosin resin raw material is fed into the inside of the feeding box 4 through the discharge port 41. Then, the first motor 45 drives the transmission rod 44 to make the crushing blade 46 at the bottom rotate to crush the rosin resin. After being filtered by the filter screen 43, the reduced rosin resin can flow out to the discharge port 42 for dissolution, thereby accelerating the dissolution rate.

[0028] Please see Figure 3 A filter box 6 is installed on one side of the top of the melting box 1, and an openable door is provided on the outside of the filter box 6 to facilitate the replacement of the internal adsorption layer 114. A suction pipe 8 is provided on one side of the filter box 6, passing through the upper end of the upper rotating cavity 12. The filter box 6 contains an adsorption layer 114. A fan 7 is installed on the top of the melting box 1 at the rear end of the filter box 6, and the suction end of the fan 7 passes through the interior of the filter box 6. A filter screen can be installed at the suction end to prevent the rosin resin from being sucked out. A water tank 9 is installed on the other side of the top of the melting box 1. The exhaust end of the fan 7 passes through the interior of the water tank 9 through a conduit 10. Several air holes 11 are provided at the upper end of the water tank 9, and a water exchange port is provided at the bottom of the water tank 9 to facilitate water replacement. Under the operation of the fan 7, the gas generated during the dissolution process can be adsorbed by the adsorption layer 114 and then input into the water tank 9 for purification under the action of the internal purification liquid, thereby reducing the impact of waste gas.

[0029] Working principle: In use, first connect the first motor 45, the second motor 5, the fan 7, the heating element 16, the solenoid valve 111 and the controller 3, and connect them to an external power supply. Then, rosin resin is fed into the inside of the feeding box 4 through the feed port 41. The first motor 45 drives the transmission rod 44 to rotate the crushing blade 46, which can crush the rosin resin inside the feeding box 4. The crushed raw material is filtered through the filter screen 43 and fed downward into the upper rotating cavity 12 inside the melting box 1 through the discharge port 42. Under the action of the heating element 16 in the internal heating tank 15, it is heated and dissolved. At the same time, the second motor 5 drives the rotating shaft 17 to rotate the stirring rod 18, which can accelerate the dissolution rate. Then, the liquid and solid are separated by the middle filter screen 14, so that the liquid enters the lower rotating cavity 13 and is discharged through the bottom drain 110, thus completing the work.
