Description

Technical Field

[0001] The utility model relates to a raw material conveying system. Background Art

[0002] In the daily production process of mixing glue, a large amount of liquid resin raw materials and various solvents are required for production. For each batch of products produced, various different epoxy resin raw materials are used once or multiple times. At present, the raw materials are stored in storage tanks, and all materials are conveyed by a conveying pump to achieve the raw material conveying in a fully enclosed manner. Due to the nature of the raw materials themselves, they cannot be stored at high temperatures for a long time. When the temperature in the storage tank is too low, the viscosity of the epoxy resin stored in the storage tank becomes larger. When the conveying pump transports the materials to the workshop, the operation of the conveying pump becomes larger, causing the conveying material pipeline to vibrate as a whole, and the large vibration of the pipeline affects the service life of the pipeline welds, thereby affecting the service life of the material pipeline. At the same time, during the use process, the filter bag inside the filter is prone to residual raw materials, resulting in a short service life of the filter and frequent replacement.

[0033] The descriptions of the following embodiments refer to the accompanying drawings to exemplify specific embodiments in which the present utility model can be implemented.

[0034] As Figure 1 shown, this embodiment discloses a raw material conveying system, which includes a raw material storage tank 1, a conveying pump 2, a filter 3, a nitrogen supply device 4, a first metal hose 5, a second metal hose 6, and a third metal hose 7. The filter 3 has a raw material inlet 31, a discharge port 32, and a cleaning inlet 33. The two ends of the first metal hose 5 are respectively connected to the outlet of the raw material storage tank 1 and the inlet of the conveying pump 2, and the two ends of the second metal hose 6 are respectively connected to the outlet of the conveying pump 2 and the raw material inlet 31, so that the raw materials in the raw material storage tank 1 sequentially pass through the first metal hose 5, the conveying pump 2, the second metal hose 6, the filter 3 and are discharged outward through the discharge port 32.

[0035] The raw material storage tank 1 is used to store raw materials, and the transfer pump 2 is used to provide driving force, so that the raw materials in the raw material storage tank 1 pass through the first metal hose 5, the transfer pump 2, the second metal hose 6 and the raw material inlet 31 in sequence and enter the filter 3. After being filtered by the filter 3, it is discharged out through the discharge port 32 to the pipeline ready to enter the workshop for production use. By respectively installing the first metal hose 5 and the second metal hose 6 at the inlet and outlet of the transfer pump 2, even if the transfer pump 2 generates large vibrations during use, the first metal hose 5 and the second metal hose 6 effectively solve the vibration problem of the raw materials during transportation, effectively prevent the vibration from being transmitted to the raw material storage tank 1 and the filter 3, and eliminate the friction between the material pipeline and the pipe support caused by vibration, avoid the accident of pipeline breakage due to pipeline vibration, effectively avoid the direct economic loss and environmental pollution caused by material leakage, reduce the safety hazards existing in the raw material transportation system, and ensure the normal use of production.

[0036] Both ends of the third metal hose 7 are respectively connected to the nitrogen supply device 4 and the cleaning inlet 33. The nitrogen supply device 4 is used to supply nitrogen, and the nitrogen passes through the third metal hose 7 and the cleaning inlet 33 and enters the filter 3 to clean the filter 3. By installing the third metal hose 7 between the nitrogen supply device 4 and the filter 3, the nitrogen supplied by the nitrogen supply device 4 enables the nitrogen to enter the filter 3 through the third metal hose 7 and the cleaning inlet 33. The nitrogen entering the filter 3 can purge the residual resin inside the filter 3, enabling the filter 3 to have a long service life, reducing the replacement frequency, improving the production effect, and reducing costs. At the same time, the third metal hose 7 effectively solves the vibration problem during nitrogen transportation, avoids the accident of pipeline breakage due to pipeline vibration, reduces the safety hazards existing in the raw material transportation system, and ensures the normal use of production.

[0037] The raw material transportation system further includes a first check valve 8. Both ends of the first check valve 8 are respectively connected to the second metal hose 6 and the filter 3. The inlet of the first check valve 8 is communicated with the second metal hose 6, and the outlet of the first check valve 8 is communicated with the filter 3. The raw materials in the raw material storage tank 1 pass through the first metal hose 5, the transfer pump 2, the second metal hose 6, the first check valve 8 and the raw material inlet 31 in sequence and enter the filter 3. By arranging the first check valve 8 between the second metal hose 6 and the filter 3, it effectively prevents the raw materials from flowing back, maintains the pressure stability in the system, and thus improves the safety and stability of the raw material transportation system.

[0038] The raw material conveying system further includes a reflux storage tank 9. The outlets of the first one-way valves 8 are connected to both the reflux storage tank 9 and the raw material inlet 31 and are in communication with the reflux storage tank 9 and the filter 3. The first one-way valves 8 are used to block the reverse-flow raw materials, enabling the reflux storage tank 9 to store the refluxed raw materials, realizing recycling and cost savings.

[0039] The raw material conveying system further includes a detection device, which is connected to the outlet of the second metal hose 6. The conveying pump 2 conveys the raw materials through the outlet of the second metal hose 6 and the first one-way valves 8 in sequence and into the filter 3. The detection device is used to detect the conveyed raw materials in real time, clearly understand the conveying situation, and thus ensure the safety and stability of the raw material conveying system. Among them, the detection device includes a pressure gauge 10, and the internal pressure of the raw material conveying system is detected in real time through the pressure gauge.

[0040] The raw material conveying system further includes an additional filter 11. The inlet and outlet of the additional filter 11 are respectively connected to the first metal hose 5 and the conveying pump 2. The additional filter 11 plays a filtering role. The raw materials in the raw material storage tank 1 are conveyed to the first metal hose 5 and the additional filter 11 in sequence by the driving force provided by the conveying pump 2, and then enter the conveying pump 2. The additional filter 11 filters the raw materials entering the conveying pump 2 first, effectively preventing impurities from entering the conveying pump 2 and causing damage to the conveying pump 2, improving the safety and stability of the raw material conveying system; at the same time, the service life of the conveying pump 2 is prolonged, the replacement frequency is reduced, the production effect is improved, and the cost is reduced.

[0041] The raw material conveying system further includes a second one-way valve 12. The inlet and outlet of the second one-way valve 12 are respectively connected to the nitrogen supply device 4 and the third metal hose 7. The nitrogen provided by the nitrogen supply device 4 enters the filter 3 through the second one-way valve 12, the third metal hose 7 and the cleaning inlet 33 in sequence. The second one-way valve 12 is used to block, preventing the nitrogen and residual resin entering the filter 3 from flowing back and maintaining the pressure stability in the system, thereby improving the safety and stability of the raw material conveying system.

[0042] In this embodiment, flange connection parts are provided at both ends of the first metal hose 5, the second metal hose 6 and the third metal hose 7. The first metal hose 5, the second metal hose 6 and the third metal hose 7 are respectively connected to the flange structures of the raw material storage tank 1, the conveying pump 2, the filter 3 and the nitrogen supply device 4 through the flange connection parts. The first metal hose 5, the second metal hose 6 and the third metal hose 7 are respectively connected to the flange structures of the raw material storage tank 1, the conveying pump 2, the filter 3 and the nitrogen supply device 4 through the flange connection parts. The flange connection method is adopted, making the installation connection very convenient and having high connection stability.

[0043] Among them, the flange connection part and the flange structure are connected by bolts, and a sealing gasket is pressed between the flange connection part and the flange structure. The sealing gasket can effectively enhance the sealing performance between the structures, enabling the raw material conveying system to convey raw materials in a fully enclosed manner, with high stability. At the same time, the flange connection part and the flange structure are connected by bolts, which is very convenient for installation and disassembly. It effectively avoids the loosening of the bolts at the pipe flange connection and the wear of the sealing gasket between the flange connection part and the flange structure, effectively avoiding the direct economic losses and environmental pollution caused by material leakage, and greatly improving the safety and stability of the raw material conveying system.
