Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a self-cleaning epoxy resin addition mixing equipment. Background Technology

[0002] With the development of chemical machinery and automated mixing technology, integrated continuous addition and mixing equipment for epoxy resin production has emerged. This type of equipment typically transports raw materials through fixed pipelines and completes the mixing operation in a single mixing tank, featuring compact structure and continuous production.

[0003] In related technologies, a single mixing tank combined with an external pumping pipeline is typically used. The mixing of epoxy resin and additives is achieved by driving the mixing blades with a motor, and the pipeline is kept clean by manual rinsing or disassembly during production breaks.

[0004] However, the above-mentioned mixing equipment and production method have the following drawbacks:

[0005] First, the pipeline system lacks cleaning capabilities, and residual materials are prone to solidification and accumulation, resulting in high maintenance costs and long downtime.

[0006] Secondly, the lack of a rotation mechanism for long-term continuous operation of a single mixing tank makes mechanical parts prone to fatigue wear due to continuous load, affecting equipment life and production stability. Utility Model Content

[0007] In response to the shortcomings of the existing production technology, the applicant provides a self-cleaning epoxy resin addition and mixing device. After production is completed, all pipelines can be self-cleaned by adding a cleaning agent into the storage tank before being discharged.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A self-cleaning epoxy resin addition and mixing device includes:

[0010] The main agent storage tank and the curing agent storage tank are arranged side by side;

[0011] The outlet of the main agent storage tank is connected to the first gear pump via a pipeline, and the first gear pump is connected to the first mixing tank and the second mixing tank via branch pipelines respectively.

[0012] The outlet of the curing agent storage tank is connected to a second gear pump via a pipeline, and the second gear pump is connected to the first mixing tank and the second mixing tank via branch pipelines respectively.

[0013] The first mixing tank is equipped with a first weighing sensor, and the second mixing tank is equipped with a second weighing sensor;

[0014] The outlet ends of the first and second mixing tanks are both connected to a spray pump, and the outlet end of the spray pump is equipped with a first manual ball valve and a second manual ball valve with selectable passage.

[0015] The first manual ball valve is connected to an external outlet, and the second manual ball valve is connected to the next process equipment via a metal hose;

[0016] The first and second mixing tanks alternately perform mixing operations, and after production is completed, cleaning agent is added to the main agent storage tank and the curing agent storage tank to clean the pipeline.

[0017] As a further improvement to the above technical solution:

[0018] In one embodiment, both the first and second mixing tanks are equipped with a drive motor at their top, and the output end of the drive motor is connected to the mixing element inside the mixing tank via a coupling.

[0019] In one embodiment, the first weighing sensor and the second weighing sensor monitor the weight of the material in the corresponding mixing tank and trigger the next round of metering and mixing operation when the weight reaches zero.

[0020] In one embodiment, the first gear pump and the second gear pump are metering gear pumps used to control the delivery amount of the main agent and the curing agent.

[0021] In one embodiment, the first manual ball valve and the second manual ball valve are three-way ball valves.

[0022] In one embodiment, the metal hose is a flexible stainless steel hose for connection to a downstream mixing pot.

[0023] In one embodiment, the top of the main agent storage tank and the curing agent storage tank is provided with a cleaning agent filling port for adding cleaning agent after production is completed.

[0024] In one embodiment, the first and second mixing tanks have the same volume and are arranged symmetrically.

[0025] In one embodiment, the cleaning agent enters the pipeline system via the main agent storage tank and the curing agent storage tank, flows through the first gear pump, the second gear pump, the first mixing tank and the second mixing tank, and is finally discharged through the first manual ball valve and the external outlet.

[0026] The beneficial effects of this utility model are as follows:

[0027] This utility model has a compact structure and breaks the traditional single-tank production mode by alternating operation of the first and second mixing tanks in parallel. When one mixing tank completes mixing and discharges the material to the next process, the other mixing tank performs metering, mixing and discharge of a new batch of material, eliminating waiting time and enabling the epoxy resin addition and mixing process to achieve truly uninterrupted continuous production, significantly improving overall production efficiency.

[0028] This utility model also has the following advantages:

[0029] During cleaning, this utility model only requires adding cleaning agent to the storage tanks of the main agent and the curing agent. The cleaning agent will then flow through all parts in contact with the material using the equipment's existing delivery pipelines and pumps, and finally be discharged through the external outlet. This eliminates the need for tedious manual disassembly and cleaning, greatly reducing maintenance intensity and time, and minimizing quality risks and production interruptions caused by incomplete cleaning.

[0030] The alternating operation mechanism of the mixing tanks in this invention provides rest time for the equipment. Each mixing tank, its drive motor, and mixing components have an interval after completing one operation, thereby avoiding a single mixing tank from operating under continuous high load for a long time. This effectively reduces fatigue wear of mechanical components, lowers the failure rate, extends the overall service life of the equipment, and ensures the stability of the production process.

[0039] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0040] like Figures 1-2 The accompanying drawing shows a structural schematic diagram of a self-cleaning epoxy resin addition and stirring device according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0041] This application provides a self-cleaning epoxy resin addition and stirring device, including a main agent storage tank 1 and a curing agent storage tank 2 arranged side by side, which are used to store the main agent and curing agent of epoxy resin, respectively.

[0042] In some embodiments, the outlet of the main agent storage tank 1 is connected to the inlet of the first gear pump 3 via a pipeline, and the outlet of the first gear pump 3 is divided into two branch pipelines via a three-way connector, which are respectively connected to the feed inlets at the top of the first mixing tank 5 and the second mixing tank 6.

[0043] Similarly, the outlet of the curing agent storage tank 2 is connected to the inlet of the second gear pump 4 via a pipeline. The outlet of the second gear pump 4 is also divided into two branch pipelines via a tee connector, which are respectively connected to another feed port at the top of the first mixing tank 5 and the second mixing tank 6.

[0044] Furthermore, the first gear pump 3 and the second gear pump 4 are preferably metering gear pumps, which can precisely control the delivery amount of the main agent and the curing agent.

[0045] In some embodiments, the first mixing tank 5 and the second mixing tank 6 are arranged side by side, with symmetrical structure and the same volume; a drive motor (not marked separately in the figure) is fixedly installed on the top of each mixing tank, and the output shaft of the drive motor is connected to the stirring component (such as a paddle or anchor mixer) set in the tank through a coupling, for stirring and mixing the material in the tank.

[0046] Furthermore, a first weighing sensor 7 is installed on the bottom support or support structure of the first mixing tank 5, and a second weighing sensor 8 is installed at the corresponding position of the second mixing tank 6; wherein, the first weighing sensor 7 and the second weighing sensor 8 are used to monitor the total weight of the material in their respective mixing tanks in real time, and provide signals for the measurement and control of alternating operations.

[0047] In some embodiments, the bottom outlets of the first mixing tank 5 and the second mixing tank 6 are respectively connected to the inlet of a spray pump 9 via pipelines, and the outlet end of the spray pump 9 is connected to a three-way valve assembly.

[0048] Specifically, the valve assembly includes a first manual ball valve 10 and a second manual ball valve 12;

[0049] The outlet of the first manual ball valve 10 is connected to an external drain port 11 for discharging cleaning waste liquid.

[0050] The outlet of the second manual ball valve 12 is connected to a metal hose 13, which is preferably a flexible stainless steel hose, for conveying the mixed epoxy resin material to the mixing pot of the next process during production.

[0051] The first manual ball valve 10 and the second manual ball valve 12 together form a selection path. By operating the opening and closing state of the valves, the flow of materials to the next process or the discharge of cleaning waste liquid to the external discharge port 11 can be switched.

[0052] The working process of this utility model is as follows:

[0053] In normal production mode, the first manual ball valve 10 is closed and the second manual ball valve 12 is open;

[0054] Assuming that the first mixing tank 5 is started first, the first gear pump 3 and the second gear pump 4 are started, and the main agent and curing agent are pumped into the first mixing tank 5 in proportion respectively. The first weighing sensor 7 monitors the feeding weight in real time, and stops feeding after the set value is reached.

[0055] The drive motor starts, driving the mixing components to mix and stir.

[0056] At the same time, the second mixing tank 6 can begin receiving the next batch of materials for metering and pre-mixing.

[0057] Once the material in the first mixing tank 5 has been mixed, its corresponding spray pump 9 is started, pumping the material to the next process through the second manual ball valve 12 and the metal hose 13.

[0058] Once the first weighing sensor 7 detects that the material inside the tank has been emptied (weight returns to zero), the first mixing tank 5 can prepare for the next round of metering and mixing.

[0059] At this point, the second mixing tank 6 has completed the addition of materials and can immediately take over the mixing and discharging operation.

[0060] In this way, the first mixing tank 5 and the second mixing tank 6 alternately carry out mixing and discharging operations, realizing continuous production.

[0061] When cleaning is required after production, add an appropriate amount of cleaning agent to the top filling port (not shown in the figure) of the main agent storage tank 1 and the curing agent storage tank 2.

[0062] Then, the first gear pump 3, the second gear pump 4, and the spray pump 9 are started, so that the cleaning agent flows sequentially through the original material conveying pipeline, the first gear pump 3, the second gear pump 4, the first mixing tank 5, the second mixing tank 6, and the spray pump 9.

[0063] At this time, the second manual ball valve 12 is closed and the first manual ball valve 10 is opened. The waste liquid after cleaning is discharged from the external drain port 11 through the first manual ball valve 10, thereby completing the self-cleaning of the entire pipeline system without disassembling any parts.

[0064] In summary, this utility model avoids mechanical fatigue of the equipment by alternating the operation of the first mixing tank 5 and the second mixing tank 6; in addition, it has the function of cleaning pipelines, which effectively improves production efficiency, equipment service life and maintenance convenience.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
