Description

Technical Field

[0001] The present invention belongs to the technical field of binder production, and particularly relates to an automatic binder preparation system. Background Art

[0002] A binder is a substance that can tightly bond two or more materials through surface adhesion and is widely used in industries, construction, medical treatment, electronics, etc. The main classifications include: inorganic binders (such as cement, ceramic binders, etc.), organic binders (such as starch-based, protein-based binders, epoxy resins, polyurethanes, and acrylics, etc.), and thermoplastic (such as hot melt adhesives) / thermosetting binders (such as phenolic resins).

[0003] Currently, most of the existing automatic binder preparation systems use tanks to prepare organic binders. However, due to the viscosity of the organic binder itself, after the preparation is completed, the residues are easily adhered to the stirring rod and the bottom of the tank, making the cleaning work of the tank more difficult and incomplete, bringing a greater burden to the cleaning personnel. In addition, due to mechanical connection, the sealing performance at the connection part between the tank body and the tank cover may not be ideal after long-term connection and use, resulting in easy leakage during use, and further possibly leading to the leakage of odor gases.

[0004] In summary, the existing automatic binder preparation systems have problems of inconvenient cleaning and easy leakage, polluting the environment. Summary of the Invention

[0005] The present invention provides an automatic binder preparation system, which can solve the problems of inconvenient cleaning and easy leakage, polluting the environment existing in the existing automatic binder preparation systems.

[0006] To achieve the above object, according to an embodiment of the first aspect of the present invention, an automatic binder preparation system is proposed, including a preparation tank;

[0007] A stirring device, arranged on the preparation tank, for stirring and preparing the binder;

[0008] The preparation tank includes an outer tank, an inner tank and a tank cover. A cavity is formed between the outer tank and the inner tank. A notch is opened in the top surface port of the outer tank, and the tank cover is arranged in the notch. A pair of electric lifting rods are fixedly installed in the cavity, and the top surfaces of the rod bodies of the electric lifting rods are fixedly connected to the bottom surface of the tank cover;

[0009] It further includes:

[0010] A sealing assembly, which includes a sealing ring fixedly installed in the notch, a sealing convex ring fixedly installed at the bottom edge of the tank cover, and a sealing cover fixedly installed on the bottom surface of the tank cover.

[0011] A further improvement lies in that the stirring device is arranged on the tank cover. The stirring device includes a mixing rod arranged in the inner tank, mixing blades fixedly sleeved on the mixing rod, and a DC servo motor fixedly installed on the tank cover with the main shaft passing through the tank cover and connected to the mixing rod.

[0012] A further improvement lies in that a pair of cleaning support rods are fixedly sleeved on the mixing rod, and cleaning blades are arranged on each cleaning support rod.

[0013] A further improvement lies in that each cleaning blade and each cleaning support rod are integrally formed, and each cleaning blade contacts the inner wall of the inner tank.

[0014] A further improvement lies in that the sealing convex ring is divided into a ring and a ring body. The ring is sleeved on the ring body, and the surfaces of the ring and the ring body are at the same height.

[0015] A further improvement lies in a heat dissipation component. The heat dissipation component includes a centrifugal fan fixedly installed on the outer tank, an air suction pipe fixedly installed at the input end of the centrifugal fan and connected to the outer tank, a purification filter cylinder arranged on one side outside the outer tank, and a guide pipe fixedly installed at the output end of the centrifugal fan and connected to the purification filter cylinder. An activated carbon adsorption filter element is fixedly installed in the purification filter cylinder.

[0016] A further improvement lies in that the purification filter cylinder is provided with an air inlet and an air outlet, and the guide pipe is connected to the air inlet.

[0017] A further improvement lies in that a plurality of connection ports are equidistantly arranged on the outer tank. The air suction pipe is arranged around the upper edge of the outer tank, and a plurality of branch pipes are arranged on the inner side of the air suction pipe. Each branch pipe is respectively connected to each connection port.

[0018] A further improvement lies in that a pair of electric lifting rods are respectively fixedly installed on the inner side of the outer tank through fixing bolts.

[0019] A further improvement lies in that a feeding port and an injection pipeline are arranged on the tank cover.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) After the binder is prepared in the present invention, under the synchronous rotation of the mixing rod, a pair of each cleaning support rod is driven to rotate, so that the cleaning blades on each cleaning support rod scrape the residues on the inner wall of the inner tank. After the scraping is completed, the rod bodies of a pair of electric lifting rods drive the tank cover and the sealing cover to lift, and the stirring device is lifted out of the inner tank. This design facilitates the later comprehensive cleaning of the inner tank, the mixing rod and the cleaning support rods by the cleaning personnel, without disassembling and assembling the whole stirring device, and the operation and use are very convenient.

[0022] (2) During the preparation process of the adhesive in the present invention, a sealing convex ring is provided at the bottom edge of the can lid. This sealing convex ring is divided into two parts: a ring and a ring body, and the ring is sleeved on the ring body. After the can lid is clamped into the notch on the top surface of the outer can, the ring body contacts the sealing ring in the notch, and the bottom surface of the ring contacts the sealing ring and the top surface of the outer can. This design effectively improves the sealing effect after connection and avoids gas leakage during use.

[0023] (3) In the present invention, by starting the centrifugal fan, its impeller rotates to generate negative pressure. A number of connection ports are equidistantly arranged on the outer can. The suction pipe is arranged around the upper edge of the outer can, and a number of branch pipes are provided on the inner side of the suction pipe. Each branch pipe is respectively connected to each connection port. Utilizing the negative pressure of the centrifugal fan, the heat in the inner can is inhaled and discharged through the branch pipes and the suction pipe, effectively avoiding the influence of too high temperature on the performance of the adhesive, thereby improving the production quality of the adhesive.

[0024] (4) While dissipating heat in the present invention, if leakage occurs, the leaked gas first diffuses in the cavity between the inner can and the outer can, and then under the negative pressure generated by the centrifugal fan, it is inhaled by the gas and filtered and adsorbed by the activated carbon adsorption filter element in the purification filter cylinder, and finally discharged from the exhaust port on the purification filter cylinder. This design of the present invention further effectively prevents a series of consequences caused by the inability to handle gas leakage, and enhances the use effect of the system device.

[0035] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0036] As Figures 1 to 5 shown, an automatic adhesive preparation system includes a preparation tank body 2, the preparation tank body 2 includes an outer tank 22, an inner tank 23 and a tank cover 21. A cavity is formed between the outer tank 22 and the inner tank 23. A notch 201 is opened in the top surface port of the outer tank 22. A pair of electric lifting rods 202 are fixedly installed inside the outer tank 22, and the top surfaces of the rod bodies of the electric lifting rods 202 are fixedly connected to the bottom surface of the tank cover 21;

[0037] It should be noted that a feeding port and an injection pipeline are provided on the tank cover 21 for adding adhesive raw materials. A feeding pipeline is provided at the bottom of the configuration tank body 2, and the feeding pipeline is communicated with the inner tank 23. The raw materials added in this embodiment are based on organic adhesive raw materials; in addition, a pressure relief exhaust pipe is also provided, and the pressure relief exhaust pipe is connected to a pressure relief component in the system, which is configured before implementation and will not be elaborated in this embodiment;

[0038] A stirring device 3 is provided on the tank cover 21 for stirring and preparing the adhesive;

[0039] Specifically, the stirring device 3 includes a mixing rod 32 arranged in the inner tank 23, mixing blades 33 fixedly sleeved on the mixing rod 32, and a DC servo motor 31 fixedly installed on the tank cover 21 and whose main shaft passes through the tank cover 21 and is connected to the mixing rod 32;

[0040] It should be noted that the main shaft end of the DC servo motor 31 is connected to a speed reducer, and the speed reducer is connected to the mixing rod 32 for coordinated use. By starting a pair of electric lifting rods 202 to contract, the tank cover 21 is clamped in the notch 201 on the top surface of the outer tank 22, and the sealing cover 43 is covered on the top surface port of the inner tank 23. Then start the DC servo motor 31 to drive the speed reducer and the mixing rod 32 to rotate, and the mixing blades 33 on the mixing rod 32 stir the raw materials to realize the automatic preparation of the adhesive;

[0041] As a preferred embodiment, a pair of cleaning support rods 34 are fixedly sleeved on the mixing rod 32. Each cleaning support rod 34 is provided with a cleaning blade 35. Each cleaning blade 35 and each cleaning support rod 34 are integrally formed. Each cleaning blade 35 contacts the inner wall of the inner tank 23. Under the synchronous rotation of the mixing rod 32, a pair of each cleaning support rod 34 is driven to rotate, so that the cleaning blades 35 on each cleaning support rod 34 scrape off the residues on the inner wall of the inner tank 23, reducing the cleaning burden of the cleaning personnel;

[0042] Sealing assembly 4, the sealing assembly 4 includes a sealing ring 41 fixedly installed in the notch 201, a sealing convex ring 42 fixedly installed at the bottom edge of the tank cover 21 and a sealing cover 43 fixedly installed on the bottom surface of the tank cover 21;

[0043] Specifically, the sealing convex ring 42 is divided into a ring 421 and a ring body 422. The ring 421 is sleeved on the ring body 422, and the surfaces of the ring 421 and the ring body 422 are at the same height. During the preparation process, a sealing convex ring 42 is provided at the bottom edge of the tank cover 21. The sealing convex ring 42 is divided into two parts, a ring 421 and a ring body 422. The ring 421 is sleeved on the ring body 422. After the tank cover 21 is clamped in the notch 201 on the top surface of the outer tank 22, the ring body 422 contacts the sealing ring 41 in the notch 201, and the bottom surface of the ring 421 contacts the sealing ring 41 and the top surface of the outer tank. This design effectively improves the sealing effect after connection and avoids gas leakage during use;

[0044] Such as Figure 1 、 Figure 3 and Figure 5 As shown, this embodiment also provides another implementation scheme, which is specifically as follows:

[0045] Heat dissipation assembly 1, the heat dissipation assembly 1 includes a centrifugal fan 15 fixedly installed on the outer tank 22, an air suction pipe 16 fixedly installed at the input end of the centrifugal fan 15 and connected to the outer tank 22, a purification filter cylinder 13 arranged on one side outside the outer tank 22 and a guide pipe 14 fixedly installed at the output end of the centrifugal fan 15 and connected to the purification filter cylinder 13. An activated carbon adsorption filter element 131 is fixedly installed in the purification filter cylinder 13;

[0046] Specifically, the purification filter cylinder 13 is provided with an air inlet 11 and an air outlet 12. The guide pipe 14 is connected to the air inlet 11. A plurality of connection ports are equidistantly arranged on the outer tank 22. The air suction pipe 16 is arranged around the upper edge of the outer tank. A plurality of branch pipes 161 are arranged inside the air suction pipe 16. Each branch pipe 161 is respectively connected to each connection port, and the branch pipe 161 communicates with the cavity formed by the outer tank 22 and the inner tank 23;

[0047] In this embodiment, by starting the centrifugal fan 15, the rotation of its impeller generates negative pressure. A number of connecting ports are equidistantly arranged on the outer tank 22. The suction pipe 16 is arranged around the upper edge of the outer tank. A number of branch pipes 161 are arranged inside the suction pipe 16, and each branch pipe 161 is respectively connected to each connecting port. Utilizing the negative pressure effect of the centrifugal fan 15, the heat in the inner tank 23 is inhaled and discharged through the branch pipes 161 and the suction pipe 16, effectively avoiding the influence on the performance of the binder due to excessive temperature, thereby improving the production quality of the binder.

[0048] During heat dissipation, if leakage occurs, the leaked gas first diffuses in the cavity between the inner tank 23 and the outer tank 22, and then under the negative pressure effect generated by the centrifugal fan 15, the inhaled gas is filtered and adsorbed by the activated carbon adsorption filter element 131 in the purification filter cylinder 13, and finally discharged from the exhaust port 12 on the purification filter cylinder 13. This design of the present invention further effectively prevents a series of consequences caused by the inability to handle gas leakage, enhancing the use effect of the system device.

[0049] As Figures 1 to 5 shown, in this embodiment, it should also be noted that the actual sizes of the various components in the application documents are selected and installed before implementation according to the actual on-site requirements; among them, the centrifugal fan 15, the electric lifting rod 202, and the DC servo motor 31 are commercially available products of the prior art, and their working principles have been made public. In addition, it should be reminded that this application document only improves the disadvantages of the existing binder automatic preparation system, such as inconvenient cleaning and easy leakage and environmental pollution, and does not involve other aspects; the working principle of this binder automatic preparation system is introduced as follows:

[0050] When the present invention is in use, during the use process of the present invention, on-site workers add the raw materials for binder production into the inner tank 23 through the feeding port and the injection pipeline on the tank cover 21. Subsequently, start a pair of electric lifting rods 202 to make them contract, clamp the tank cover 21 in the notch 201 on the top surface of the outer tank 22, and make the sealing cover 43 cover the top port of the inner tank 23. Then start the DC servo motor 31 to drive the reducer and the mixing rod 32 to rotate, and the mixing blades 33 on the mixing rod 32 stir the raw materials to achieve automatic preparation of the binder.

[0051] After the binder is prepared, under the synchronous rotation of the mixing rod 32, a pair of each cleaning rack rod 34 is driven to rotate, and the cleaning blades 35 on each cleaning rack rod 34 scrape off the residues on the inner wall of the inner tank 23. After scraping, the rod bodies of a pair of electric lifting rods 202 drive the tank cover 21 and the sealing cover 43 to lift, lifting the stirring device 3 out of the inner tank 23. This design facilitates the later cleaning of the bottom and inner wall of the inner tank 23, as well as the mixing rod 32 and the cleaning rack rod 34 by the cleaning personnel, without the need to disassemble and assemble the entire stirring device 3, and the operation and use are very convenient.

[0052] During the preparation process, a sealing convex ring 42 is provided at the bottom edge of the can lid 21. The sealing convex ring 42 is divided into two parts, a ring 421 and a ring body 422, and the ring 421 is sleeved on the ring body 422. After the can lid 21 is clamped in the top surface notch 201 of the outer can 22, the ring body 422 contacts the sealing ring 41 in the notch 201, and the bottom surface of the ring 421 contacts the sealing ring 41 and the top surface of the outer can. This design effectively improves the sealing effect after connection and avoids gas leakage during use.

[0053] In addition, by starting the centrifugal fan 15, negative pressure is generated by the rotation of its impeller. A number of connection ports are equidistantly arranged on the outer can 22. The suction pipe 16 is arranged around the upper edge of the outer can. A number of branch pipes 161 are provided on the inner side of the suction pipe 16, and each branch pipe 161 is respectively connected to each connection port. Utilizing the negative pressure of the centrifugal fan 15, the heat in the inner can 23 is inhaled and discharged through the branch pipes 161 and the suction pipe 16, effectively avoiding the influence of too high temperature on the performance of the binder, thereby improving the production quality of the binder.

[0054] During heat dissipation, if leakage occurs, the leaked gas first diffuses in the cavity between the inner can 23 and the outer can 22, and then under the action of the negative pressure generated by the centrifugal fan 15, the inhaled gas is filtered and adsorbed by the activated carbon adsorption filter element 131 in the purification filter cylinder 13, and finally discharged from the exhaust port 12 on the purification filter cylinder 13. This design of the present invention further effectively prevents a series of consequences caused by the inability to handle gas leakage after leakage, and enhances the use effect of the system device.

[0055] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
