Description

Technical Field

[0001] The utility model relates to the field of curing agent filtering devices, in particular to a curing agent filtering device. Background Art

[0002] Curing agent is a kind of substance that promotes or controls the curing reaction. It is crucial to the curing of resin. It forms a hard polymer through chemical reaction. It is widely used in adhesives, coatings and other fields. There are many types of curing agents. The performance requirements of the cured material must be considered when selecting. At the same time, protective measures must be taken when using curing agents to avoid harm to the body. Curing agent is an indispensable component for resin curing, and its use can significantly improve the performance of the material.

[0003] In the current curing agent filling process, a metering pump is used to accurately meter the curing agent. However, since tiny waste materials are generated during the curing agent processing, a filtering device is usually installed at the front end of the metering pump to filter out these waste materials, thereby improving the protection performance and product quality of the metering pump. However, in actual use, we found a problem: when it is necessary to clean the filter inner cylinder inside the filter device, even if the front and rear ends of the filter are blocked by traditional valves, a part of the curing agent raw material will still remain inside. This will result in the waste of this part of the residual curing agent when the filter is disassembled for cleaning, thereby affecting the cleaning efficiency and convenience of the filter. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a curing agent filtering device to solve the technical problem that curing agent raw materials remain inside the filtering device during cleaning, resulting in curing agent waste.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a curing agent filtering device, comprising a device body, a liquid inlet pipe and a liquid outlet pipe, a cleaning mechanism is arranged on the outer side of the liquid inlet pipe and the liquid outlet pipe, the cleaning mechanism comprises a first connecting pipe and a second connecting pipe, the outer sides of the first connecting pipe and the second connecting pipe are both provided with a second valve, the end of the second connecting pipe is connected to a receiving cylinder, the end of the first connecting pipe is connected to an external air compressor, and one side of the liquid inlet pipe and the liquid outlet pipe is provided with a first valve.

[0006] By adopting the above technical solution, high-pressure airflow is introduced into the first connecting tube, thereby effectively squeezing the curing agent raw material inside the filter device. In this process, the force of the high-pressure airflow can discharge the raw material originally retained inside the device body smoothly through the second connecting tube and be collected by the receiving tube. Such operation greatly reduces the waste of raw materials when cleaning the inner filter tube.

[0007] Furthermore, the first valve is used to intercept the curing agent, and the second valve is used to intercept the high-speed airflow of the external air compressor.

[0008] By adopting the above technical solution, the first valve can intercept the curing agent to prevent it from leaking or wasting when it is not needed to flow. When cleaning or maintaining the filter inner cylinder, closing the first valve can effectively isolate the filter device to ensure that the curing agent does not flow in or out, thereby protecting the operating environment and the safety of the staff.

[0009] Furthermore, one end of the liquid inlet pipe is connected to an external curing agent storage device, and one end of the liquid outlet pipe is connected to an external metering pump.

[0010] By adopting the above technical solution, the direct connection between the liquid inlet pipe and the external curing agent storage device ensures a stable supply of curing agent, simplifies the transportation process, improves work efficiency, and reduces the risk of leakage or contamination that may occur during the transportation process.

[0011] Furthermore, the device body includes a shell, and a first side cover and a second side cover are detachably provided on both sides of the shell.

[0012] By adopting the above technical solution, a convenient maintenance and cleaning method is provided. When the filter inner cylinder or the inside of the device needs to be cleaned and maintained, the first side cover and the second side cover can be conveniently removed to easily access the inside of the device, thereby improving work efficiency.

[0013] Furthermore, a filter inner cylinder is arranged inside the outer shell, and a flow gap is formed between the filter inner cylinder and the outer shell.

[0014] By adopting the above technical solution, it is ensured that the curing agent can be effectively filtered when flowing through the device, and the fine structure of the filter inner cylinder can remove tiny wastes and impurities in the curing agent, thereby improving the purity and quality of the curing agent.

[0015] Furthermore, a clamping ring is provided on the outer side of the filter inner cylinder, and a fixing ring is provided on the inner wall of the outer shell, so as to limit the position of the filter inner cylinder.

[0016] By adopting the above technical solution, the stability of the filter inner cylinder in the device is ensured, and the coordinated use of the clamping ring and the fixing ring can effectively prevent the filter inner cylinder from moving or rotating during operation, thereby ensuring the stability and consistency of the filtering effect.

[0017] Furthermore, an exhaust port is provided on one side of the top of the receiving tube.

[0018] By adopting the above technical solution, the pressure balance inside the receiving cylinder can be ensured. When the high-pressure airflow discharges the curing agent raw material from the filtering device to the receiving cylinder, the exhaust port can discharge the air in the cylinder in time to prevent safety problems caused by excessive air pressure.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model uses a cleaning mechanism to squeeze the curing agent raw material inside the filter device through a high-pressure airflow, so that the raw material retained in the device can be effectively discharged, so that when cleaning the filter inner cylinder, the waste of raw materials can be greatly reduced. At the same time, the use of high-pressure airflow to remove the retained raw materials also makes subsequent disassembly and cleaning work easier, thereby improving the convenience of cleaning. In addition, by arranging a receiving cylinder to collect the discharged raw materials, not only environmental pollution is avoided, but also effective recovery and utilization of resources are achieved.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] Embodiment 1:

[0029] A curing agent filtering device, such as Figure 1-Figure 4 As shown, the device comprises a main body 1, a liquid inlet pipe 201 and a liquid outlet pipe 202, the outer sides of the liquid inlet pipe 201 and the liquid outlet pipe 202 are provided with a cleaning mechanism 3, the cleaning mechanism 3 comprises a first connecting pipe 301 and a second connecting pipe 302, the outer sides of the first connecting pipe 301 and the second connecting pipe 302 are both provided with a second valve 303, the end of the second connecting pipe 302 is connected with a receiving tube 304, the end of the first connecting pipe 301 is connected to an external air compressor, and one side of the liquid inlet pipe 201 and the liquid outlet pipe 202 is provided with a first valve 203, which allows high-pressure air flow to flow into the first connecting pipe 301, thereby effectively squeezing the curing agent raw material inside the filter device. In this process, the high-pressure air flow The force can discharge the raw materials originally retained inside the device body 1 smoothly through the second connecting pipe 302 and be collected by the receiving tube 304. This operation greatly reduces the waste of raw materials when cleaning the filter inner tube 4. At the same time, since the high-pressure airflow effectively removes the retained raw materials in the device, the work becomes easier and more efficient when disassembling the outer shell 101, the first side cover 102 and the second side cover 103 for deeper cleaning and maintenance. This not only improves the convenience of cleaning, but also extends the service life of the device. By setting the receiving tube 304 to centrally collect the discharged raw materials, the cleanliness of the operating environment is further ensured, and convenience is provided for the recycling of resources.

[0030] See also Figure 1 , Figure 2 , Figure 3 The first valve 203 is used to intercept the curing agent, and the second valve 303 is used to intercept the high-speed airflow of the external air compressor. The first valve 203 can intercept the curing agent to prevent it from leaking or wasting when it is not needed to flow. When cleaning or maintaining the filter inner tube 4, closing the first valve 203 can effectively isolate the filter device to ensure that the curing agent does not flow in or out, thereby protecting the operating environment and the safety of the staff. At the same time, the second valve 303 can intercept the high-speed airflow generated by the external air compressor. When it is necessary to use high-pressure airflow to clean the inside of the device, opening the second valve 303 can allow the airflow to pass smoothly; at other times, closing the second valve 303 can prevent the airflow from flowing into the device unnecessarily, avoiding waste of resources and possible safety risks, and making the use of the device more flexible and safe.

[0031] See also Figure 1 , Figure 2 , Figure 3One end of the liquid inlet pipe 201 is connected to an external curing agent storage device, and one end of the liquid outlet pipe 202 is connected to an external metering pump. The direct connection between the liquid inlet pipe 201 and the external curing agent storage device ensures a stable supply of curing agent, simplifies the transportation process, improves work efficiency, and reduces the risk of leakage or contamination that may occur during transportation. At the same time, the connection between the liquid outlet pipe 202 and the external metering pump allows the output of the curing agent to be precisely controlled, which is crucial for application scenarios that require precise proportioning of curing agents, such as coatings, adhesives and other industries. Precisely controlling the amount of curing agent used can not only improve product quality, but also reduce waste and reduce costs.

[0032] Embodiment 2:

[0033] See also Figure 1 , Figure 2 , Figure 3 The device body 1 includes a shell 101, and the two sides of the shell 101 are detachably provided with a first side cover 102 and a second side cover 103, which provide a convenient maintenance and cleaning method. When it is necessary to clean and maintain the filter inner cylinder 4 or the inside of the device, the first side cover 102 and the second side cover 103 can be easily removed, so as to easily access the inside of the device and improve work efficiency. At the same time, the detachable side cover setting also facilitates the replacement or repair of the components of the filter device. If a component fails or wears out, the side cover can be quickly removed to inspect or replace the corresponding component, which reduces downtime and improves the overall availability of the equipment.

[0034] See also Figure 1 , Figure 2 , Figure 3 A filter inner cylinder 4 is arranged inside the outer shell 101, and a flow gap is formed between the filter inner cylinder 4 and the outer shell 101, which ensures that the curing agent can be effectively filtered when flowing through the device. The fine structure of the filter inner cylinder 4 can remove tiny waste and impurities in the curing agent, thereby improving the purity and quality of the curing agent. At the same time, the setting of the flow gap ensures that the curing agent can flow smoothly through the filter inner cylinder 4, reducing the flow resistance and improving the filtering efficiency. This structure also helps to evenly distribute the flow of the curing agent, avoiding the problems of blockage and local overload, thereby extending the service life of the filtering device.

[0035] See also Figure 2 , Figure 3A clamping ring 501 is provided on the outer side of the filter inner cylinder 4, and a fixing ring 502 is provided on the inner wall of the outer shell 101, which are used to limit the position of the filter inner cylinder 4 and ensure the stability of the filter inner cylinder 4 in the device. The coordinated use of the clamping ring 501 and the fixing ring 502 can effectively prevent the filter inner cylinder 4 from moving or rotating during operation, thereby ensuring the stability and consistency of the filtering effect. At the same time, by limiting the position of the filter inner cylinder 4, it can also prevent it from being damaged by flow impact or other external forces, thereby extending the service life of the filter inner cylinder 4. This arrangement also simplifies the installation and disassembly process of the filter inner cylinder 4 and improves the convenience of maintenance.

[0036] See also Figure 4 An exhaust port 305 is provided on one side of the top of the receiving cylinder 304, which can ensure the pressure balance inside the receiving cylinder 304. When the high-pressure airflow discharges the curing agent raw material from the filtering device to the receiving cylinder 304, the exhaust port 305 can discharge the air in the cylinder in time to prevent safety problems caused by excessive air pressure. At the same time, the exhaust port 305 also helps to reduce the gas resistance in the receiving cylinder 304, so that the curing agent raw material can flow into the cylinder more smoothly, thereby improving the collection efficiency of the raw material. In addition, the setting of the exhaust port 305 also facilitates the subsequent cleaning work, and it can be used to discharge the residual gas and volatile curing agent vapor in the cylinder to keep the receiving cylinder 304 clean.

[0037] The implementation principle of the utility model is: when it is necessary to clean the filter inner cylinder 4, first, close the first valve 203 on the outside of the liquid inlet pipe 201 and the liquid outlet pipe 202 to block the two ends of the filter device, then open the second connecting pipe 302 and the second valve 303 on the outside of the first connecting pipe 301 in turn, then control the external air compressor to generate high-pressure airflow, and pass it into the inside of the first connecting pipe 301, and use the high-pressure airflow to squeeze the curing agent raw material inside the filter device, so that the curing agent raw material retained in the device is discharged from the second connecting pipe 302 to the inside of the receiving cylinder 304, completing the collection operation of the retained raw materials inside the device and reducing the waste of raw materials. Afterwards, the device body 1 and the internal filter inner cylinder 4 are disassembled, and subsequent cleaning operations are performed to improve the cleaning convenience of the filter device.
