Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, specifically to a plastic track adhesive circulating grinding device. Background Technology

[0002] Reactors are commonly used equipment in the adhesive production process. In the traditional production of adhesives for plastic running tracks, the reactor needs to be placed at a high position, and the material is discharged from the first discharge port at the bottom by gravity. In order to improve the performance of the adhesive, various additives need to be added to the adhesive during production. The reactor is used to stir the compounds to make them evenly mixed or react fully. The adhesives and various additives in the reactor will contain insoluble impurities. Some of these impurities are difficult to remove in the later filtration device, which will reduce the quality of the adhesive.

[0003] In summary, the existing technology has the following drawbacks: 1. Impurity filtration requires additional equipment and is cumbersome to operate; 2. The presence of numerous insoluble impurities negatively impacts the quality of the adhesive. 3. Using only a mixer results in insufficient mixing and low mixing efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide an integrated system for the delivery and filtration of adhesive liquid in the production process of plastic running track adhesive.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a circulating grinding device for plastic running track adhesives, including a reaction vessel and a stirring device. The stirring device is installed inside the reaction vessel. The reaction vessel has an inlet at the top and a first outlet and a second outlet at the bottom. The first outlet is connected to the first liquid inlet of a filter device via a pipe, and the first liquid outlet of the filter device is connected to one end of a gear pump assembly via a pipe. The other end of the gear pump assembly is connected to the reaction vessel via a return liquid pipe. After the liquid in the reaction vessel is stirred, it is filtered by the filter device, and its internal insoluble impurities and clumps are filtered out. The return liquid pipe can transport the adhesive after filtration and grinding by the gear pump back to the reaction vessel, and realize the circulation of the adhesive under the stirring of the stirring device, thereby improving the stirring efficiency and reducing the content of insoluble impurities.

[0006] Furthermore, the gear pump assembly includes a motor, a coupling, and a gear pump. The motor and gear pump are connected by a coupling shaft. The second inlet of the gear pump is connected to the first outlet of the filter device via a pipe. The gear pump includes a pump housing, a driving gear, and a driven gear. The driving gear and driven gear are disposed within the pump housing and cooperate with each other. After the liquid is filtered by the filter device, there may be fine particles that have not been filtered. During the pumping process, the driving gear and driven gear mesh with each other, grinding the remaining fine particles, thereby further improving the quality of the adhesive. Because the impurities in the adhesive are mostly insoluble impurities and some agglomerated adhesive with low hardness, these impurities will not affect the gears themselves during the meshing process of the driving gear and driven gear.

[0007] Furthermore, the filtration device includes a filter housing, a filter screen, and an end cap, with the filter screen placed inside the filter housing and the end cap connected to the top of the filter housing.

[0008] Specifically, the end cap and the filter housing are connected by a quick-opening clamp, bolt flange, or rotary locking ring, which facilitates quick opening for replacement or cleaning of the filter screen.

[0009] Specifically, the top surface of the filter screen is inclined, and a sealing lip is provided at the circumference of the top surface. The sealing lip ensures a sealed contact between the filter screen and the filter housing, thereby ensuring that liquid can only be discharged through the filter screen.

[0010] Preferably, a support column is provided at the bottom of the filter housing, and the filter screen is placed on the support column. The support column can support the filter screen and prevent the filter screen from contacting the bottom surface of the filter housing, thus affecting the filtration effect.

[0011] Furthermore, a drain port is provided on the outside of the filter housing, and a drain valve is provided at the drain port. The drain port can discharge the liquid remaining inside the filter housing during cleaning.

[0012] Furthermore, the filtration devices are multiple sets connected in parallel, and each set of filtration devices has a filter valve installed in its pre-pipeline. The multiple sets of filtration devices allow for filter screen replacement or cleaning of the corresponding filter device by closing a specific filter valve without shutting down the system, thereby improving overall transfer efficiency.

[0013] Furthermore, a discharge valve is provided at the second discharge port. The second discharge port is the discharge port for the adhesive to flow to other storage devices after it has been thoroughly mixed.

[0014] Preferably, the drain valve, filter valve, and discharge valve are solenoid valves electrically connected to the controller, but ordinary valves may also be used.

[0015] The advantages and beneficial effects of this utility model are as follows: 1. A filtration device is installed to effectively filter insoluble impurities in the adhesive; 2. During the process of pumping out adhesive, the driving gear and driven gear mesh with each other, which can further grind some tiny impurities and improve the quality of the adhesive; 3. Using a gear pump to circulate the adhesive, along with a stirring device, can make the adhesive more thoroughly mixed. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] according to Figures 1-3 As shown, this utility model is a plastic track adhesive circulation grinding device, including a reaction vessel 1 and a stirring device 2. The stirring device 2 is set inside the reaction vessel 1. The top of the reaction vessel 1 is provided with a feed inlet 11, and the bottom is provided with a first discharge outlet 12 and a second discharge outlet 13. The first discharge outlet 12 is connected to the first liquid inlet 41 of the filter device 4 through a pipe 3. The first liquid outlet 42 of the filter device 4 is connected to one end of the gear pump assembly 5 through a pipe 3. The other end of the gear pump assembly 5 is connected to the reaction vessel 1 through a return liquid pipe 31.

[0020] The gear pump assembly 5 includes a motor 51, a coupling 52, and a gear pump 53. The motor 51 and the gear pump 53 are axially connected through the coupling 52. The second inlet 54 of the gear pump 53 is connected to the first outlet 42 of the filter device 4 through a pipe 3. The gear pump 53 includes a pump housing 531, a driving gear 532, and a driven gear 533. The driving gear 532 and the driven gear 533 are disposed inside the pump housing 531 and cooperate with each other.

[0021] The filter device 4 includes a filter housing 43, a filter screen 44, and an end cap 45. The filter screen 44 is placed inside the filter housing 43, and the end cap 45 is connected to the top of the filter housing 43.

[0022] A discharge valve 131 is provided at the second discharge port 13.

[0023] The specific working principle is as follows: Raw materials are poured into reactor 1 sequentially through the feed inlet 11 at the top of reactor 1. The stirring device 2 is started, and the stirring device 2 inside reactor 1 continuously stirs the raw materials to ensure uniform mixing and prevent the adhesive from clumping inside reactor 1. When the adhesive in reactor 1 is mixed to the required consistency, the gear pump assembly 5 is started. At this time, the motor 51 of the gear pump assembly 5 rotates, which drives the drive gear 532 of the gear pump 53 to rotate through the coupling 52. The driven gear 533 also rotates accordingly. At this time, the adhesive in reactor 1 flows out through the first discharge outlet 12 and reaches the first inlet 41 of the filter device 4 through the pipeline 3. The adhesive then flows into the filter housing 43 and is filtered by the filter screen 44. It then flows from the first outlet 42 into the gear pump assembly 5 connected by the pipe 3. At this point, after filtration by the filter device 4, only small particles remain, and the impurities in the adhesive are mostly insoluble impurities and some clumps of adhesive with low hardness. When passing through the gear pump 53, the impurities in the adhesive are further ground by the meshing of the driving gear 532 and driven gear 533, thereby reducing the amount of impurities in the adhesive. The treated adhesive is returned to the reactor 1 through the outlet of the gear pump 53 and the return pipe 31, achieving cyclic grinding. After the adhesive is thoroughly mixed, the discharge valve 131 at the second outlet 13 is opened, and the adhesive flows from the discharge valve 131 into other containers for later use.

[0024] like Figure 2 As shown, the top surface of the filter screen 44 is inclined, and a sealing lip 441 is provided at the circumference of the top surface.

[0025] like Figure 2 As shown, a support column 431 is provided at the bottom of the filter housing 43, and the filter screen 44 is placed on the support column 431.

[0026] like Figure 2As shown, a drain port 432 is provided on the outside of the filter housing 43, and a drain valve 433 is provided at the drain port 432. When the transfer work is completed or the filter screen 44 needs to be cleaned, the drain valve 433 can be opened when the machine is stopped to drain the residual adhesive from the drain port 432. Then, water or cleaning solution can be used for thorough cleaning to prevent internal clumping.

[0027] like Figure 1 As shown, the filter devices 4 are multiple sets connected in parallel, and each set of filter devices 4 has a filter valve 40 installed in the pre-pipeline 3. The multiple sets of filter devices 4 allow for the replacement or cleaning of the filter screen 44 of the filter device 4 corresponding to the filter valve 40 without stopping the machine, by closing a certain filter valve 40, thereby improving the overall transfer efficiency.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
