Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically a collaborative high-temperature viscous medium storage and conveying device. Background Technology

[0002] Chemical plants need to transfer high-temperature, viscous resins from melting tanks to other processing tanks for further treatment. For materials with high temperature and viscosity, traditional conveying methods (such as pumping and gravity flow) often suffer from low efficiency, equipment blockage, or damage. Especially in high-temperature environments, the viscosity of materials is typically high, making smooth material transport difficult using traditional methods. Therefore, a new material transport method is urgently needed to address the impact of high temperature and viscosity on conveying.

[0003] Patent CN201610152755.9 discloses a material conveying device that combines a mechanical pump and a heating device, aiming to solve the problem of conveying high-temperature viscous materials. This device uses a mechanical pump for material transfer; however, for viscous materials, especially at high temperatures, the conveying efficiency of the mechanical pump is low, and it is prone to blockages or equipment wear. Although the heating device can maintain the temperature of the material, due to the high viscosity of the material, it is still difficult to ensure smooth flow.

[0004] Patent CN202210133889.4 discloses a gas-assisted conveying device that uses compressed air to assist in the conveying of high-temperature materials. It utilizes the pressure difference of the gas to push the material to a receiving tank. Although this solution uses the pressure difference of the gas to propel the material, due to the poor flowability of high-temperature viscous materials, gas flow cannot completely solve the problem of material viscosity. Higher gas pressure may be required for effective conveying, which would increase equipment costs and potentially damage the material.

[0005] Patent CN201710144229.7 discloses a device for extracting high-temperature materials using a vacuum system to reduce material viscosity and improve flowability. The material is drawn into a receiving container via vacuum extraction. While vacuum technology is used, this solution primarily relies on vacuuming for material transport, failing to incorporate a pressurization system to propel the material flow. Vacuum technology alone may not provide sufficient driving force when dealing with high-viscosity materials, leading to unstable transport processes and low efficiency.

[0006] To address the above problems, this application provides a collaborative high-temperature viscous medium storage and conveying device to overcome the shortcomings of existing technologies in the transmission of high-viscosity materials. Utility Model Content

The storage tank is provided with a pressurizing pipe connected to the outlet of an external gas compressor, and the receiving tank is provided with a negative pressure pipe connected to the inlet of an external vacuum pump.

[0010] As a preferred embodiment of this utility model, the side of the sliding sleeve is provided with a cylinder for driving the sealing plunger to move.

[0012] As a preferred embodiment of this utility model, a heater is provided at the lower end of the interior of the storage tank, and a heat-conducting rod is provided on the heater.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a collaborative high-temperature viscous medium storage and conveying device, including a storage tank 3, a connecting pipe 1, and a receiving tank 4. The discharge pipe 31 of the storage tank 3 and the inlet pipe 41 of the receiving tank 4 are connected by the inclined connecting pipe 1, and the discharge port of the discharge pipe 31 is higher than the inlet of the inlet pipe 41. The storage tank 3 is provided with a pressurizing pipe 32 connected to the outlet of an external gas compressor, and the receiving tank 4 is provided with a negative pressure pipe 42 connected to the inlet of an external vacuum pump. The storage tank 3 and the receiving tank 4 are arranged with a gradient position difference, and the fluidity of the medium is improved by combining pressurization and negative pressure with the weight of the medium. The medium can be efficiently and stably conveyed from the storage tank 3 to the receiving tank 4.

A cylinder 71 is provided on the side of the sliding sleeve 7 to drive the sealing plunger 6 to move. The cylinder 71 controls the movement of the sealing plunger 6 and moves the sealing plunger 6 out of the discharge pipe 31. At this time, the medium in the storage tank 3 enters the receiving tank 4 through the connecting pipe 1 under the action of pressurization and negative pressure.

[0025] Furthermore, the lower interior of the storage tank 3 has two symmetrically arranged inclined surfaces, which facilitates the entry of the medium into the guide channel 5, and then discharges it through the discharge pipe 31.

[0026] Furthermore, a heater 8 is provided at the lower end of the storage tank 3. A heat-conducting rod 81 is provided on the heater 8. The heater 8 is controlled by an external switch. The heater 8 heats the medium inside the storage tank 3 through the heat-conducting rod 81 to prevent the medium temperature from dropping and causing the viscosity to increase.

[0027] Furthermore, both the discharge pipe 31 and the feed pipe 41 include a horizontal section and an inclined section. The outer side of the inclined section of the discharge pipe 31 and the outer side of the inclined section of the feed pipe 41 are provided with threads. Both ends of the connecting pipe 1 are rotatably provided with threaded rings 2. The inclined section of the discharge pipe 31 is threadedly connected to the upper threaded ring 2, and the inclined section of the feed pipe 41 is threadedly connected to the lower threaded ring 2. The discharge pipe 31 and the feed pipe 41 are connected to the connecting pipe 1 through the threaded rings 2.

[0028] Furthermore, a pressure valve 33 is provided on the pressure pipe 32 to ensure the sealing of the storage tank 3 during the storage stage.

[0029] Furthermore, a negative pressure valve 43 is provided on the negative pressure pipe 42 to ensure the sealing of the receiving tank 4 during the storage stage.

[0032] When using:

[0033] The storage medium in both storage tank 3 and receiving tank 4 is in the temperature range of 60-300°C.

[0034] An external vacuum pump extracts the vacuum level inside receiving tank 4 to between -0.01 MPa and -0.1 MPa.

[0035] The external gas compressor pressurizes storage tank 3 in the range of 0.01-0.5 MPa;

[0036] The heater 8 is controlled by an external switch. The heater 8 heats the medium inside the storage tank 3 through the heat-conducting rod 81 to prevent the medium temperature from dropping and causing the viscosity to increase.

[0037] The cylinder 71 controls the movement of the sealing plunger 6 and moves the sealing plunger 6 out of the discharge pipe 31. At this time, the medium in the storage tank 3 enters the receiving tank 4 through the connecting pipe 1 under the action of pressurization and negative pressure.

[0038] This invention employs a gradient arrangement of the storage tank 3 and the receiving tank 4, and uses a combination of pressurization and negative pressure in conjunction with the weight of the medium to improve its fluidity, thereby efficiently and stably conveying high-temperature viscous media, and is easy to use.
