Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically to a metering and conveying device for preventing pipeline blockage. Background Technology

[0002] In the existing cable insulation material production process, the conveying and metering of additives and other materials are involved. The existing related equipment generally includes a hopper, and the discharge port at the bottom of the hopper is connected to the conveying pump body through a pipe or flexible connection, and then the conveying pump body conveys the material out.

[0003] However, existing conveying and metering devices still have certain drawbacks. For example, because the discharge port is at the bottom of the hopper, bottom discharge will convey all the sediment or other impurities in the hopper, easily clogging the pipes and spray guns. Furthermore, the device involves multiple flexible connections, which are inconvenient to install and prone to damage. Clearly, these drawbacks will lead to more abnormal downtime, increasing manual workload and costs. Utility Model Content

[0004] To address the technical problems of existing conveying devices, this utility model provides a metering and conveying device to prevent pipe blockage. It consists of a pump body, a first check valve, and a second check valve, forming a suction device that achieves the effect of suctioning fluid from the top of the hopper. It also ensures that there is a gap between the end of the first pipe located in the hopper and the bottom of the hopper, so that the first pipe only sucks in the fluid and does not suck in the sediment and contaminants at the bottom of the hopper, thereby avoiding spray gun blockage and ensuring product quality.

[0005] The technical solution provided by this utility model is as follows: a metering and conveying device for preventing pipe blockage, comprising a base, a hopper, a weighing sensor, a pump body, a first one-way valve, a second one-way valve, a first pipe, a second pipe, and a spray gun; the weighing sensor is fixed on the base, the hopper is fixed on the weighing sensor, the top of the hopper is provided with an opening, one end of the first pipe is inserted into the hopper through the opening and there is a gap between it and the bottom of the hopper; the other end of the first pipe is connected to the inlet of the pump body through the first one-way valve, one end of the second pipe is connected to the outlet of the pump body through the second one-way valve, and the other end of the second pipe is connected to the spray gun.

[0006] Optionally, the distance between the end of the first pipe located inside the hopper and the bottom of the hopper is 1 / 3 to 1 / 4 of the height of the hopper.

[0007] Optionally, the height of the spray gun is higher than the height of the end of the first pipe located inside the hopper.

[0008] Optionally, a filter is provided on the second pipe.

[0011] Optionally, a support frame is provided on the base, and the drive unit is fixedly mounted on the support frame.

[0012] Optionally, a filter element is provided at the end of the first pipe located inside the hopper.

[0013] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: Addressing the technical problems of defects in existing conveying devices, this utility model utilizes a pump body, a first one-way valve, and a second one-way valve to form a suction device, achieving the effect of suctioning fluid from the top of the hopper while ensuring a gap between the end of the first pipe located inside the hopper and the bottom of the hopper. Therefore, the first pipe only suctions the fluid, without suctioning sediment and contaminants from the bottom of the hopper, thereby preventing nozzle clogging and ensuring product quality.

[0018] Example 1

[0019] Combined with appendix Figure 1 This embodiment proposes a metering and conveying device to prevent pipe blockage, including a base 1, a hopper 2, a weighing sensor 3, a pump body 4, a first one-way valve 5, a second one-way valve 6, a first pipe 7, a second pipe 8, and a spray gun 9. The weighing sensor 3 is fixed to the base 1, and the hopper 2 is fixed to the weighing sensor 3. The top of the hopper 2 has an opening. One end of the first pipe 7 is inserted into the hopper 2 through the opening, with a gap between it and the bottom of the hopper 2. The other end of the first pipe 7 is connected to the inlet of the pump body 4 through the first one-way valve 5. One end of the second pipe 8 is connected to the outlet of the pump body 4 through the second one-way valve 6, and the other end of the second pipe 8 is connected to the spray gun 9.

[0020] The metering and conveying device for preventing pipe blockage in this embodiment works as follows: During the production of high-voltage insulating materials, when it is necessary to convey additives to the main unit for mixing, the pump body 4 is activated. The fluid in the hopper 2 passes through the first pipe 7, first through the first one-way valve 5, and then into the pump body 4. Subsequently, it is sent to the spray gun 9 through the second pipe 8. In this embodiment, the first one-way valve 5 and the second one-way valve 6 are both open from the first pipe 7 to the second pipe 8, but not in the opposite direction. During the additive absorption process, the weighing sensor 3 can monitor the weight change in real time, thus allowing the operator to accurately know the amount of additive absorbed. After the material is supplied to the spray gun 9, it can be discharged through the spray gun 9 for subsequent processing.

[0021] The pump body 4 is preferably a combination of a diaphragm pump 40 and a drive unit 41. The diaphragm inside the diaphragm pump 40 is driven by the drive unit 41 to achieve a push-suction cycle. During suction, the second one-way valve 6 is closed, the first one-way valve 5 is open, and the fluid enters the diaphragm cavity from the hopper 2 through the first pipe 7. During push, the diaphragm pushes forward, the first one-way valve 5 closes, and the second one-way valve 6 opens, delivering the fluid out.

[0022] The drive unit 41 can be selected according to the model of the diaphragm pump 40. For example, when a mechanical diaphragm pump 40 is used, the drive unit 41 can be an electric drive device such as a motor. When a hydraulic diaphragm pump 40 is used, the drive unit 41 can be a suitable hydraulic drive device or system. The configuration of the diaphragm pump 40 can be directly referred to the application of existing diaphragm pump 40 products, and will not be elaborated here.

[0023] In a preferred embodiment, a support frame 13 is provided on the base 1, and the drive unit 41 is fixedly mounted on the support frame 13. As a result, the pump body 4, which is connected to the output end of the drive unit 41, is also naturally raised to a higher position, which helps to ensure that the pump body 4 can meet the requirement that its height is higher than that of the hopper 2.

[0024] To address the technical problems of existing conveying devices, this embodiment utilizes a pump body 4, a first one-way valve 5, and a second one-way valve 6 to form a suction device. This achieves the effect of suctioning fluid from the top of the hopper 2 while ensuring a gap between the end of the first pipe 7 located inside the hopper 2 and the bottom of the hopper 2. Therefore, the first pipe 7 only suctions the fluid, without suctioning sediment and contaminants from the bottom of the hopper 2, thus preventing clogging of the spray gun 9 and ensuring product quality.

[0025] Furthermore, the top discharge method allows the device to directly add a weighing sensor 3 at the bottom of the hopper 2, thereby accurately measuring the discharge amount during the suction process, ensuring the accuracy of weighing and measurement, and avoiding losses caused by incorrect material proportions.

[0026] In a preferred embodiment, the distance between the end of the first pipe 7 located inside the hopper 2 and the bottom of the hopper 2 is 1 / 3 to 1 / 4 of the height of the hopper 2. This embodiment designs the height of the suction inlet of the first pipe 7 to ensure that the material sucked into the first pipe 7 is fluid rather than sediment or other solid impurities, and this height design allows it to be as close as possible to the bottom of the hopper 2 to fully absorb the fluid portion above the sediment.

[0027] In another embodiment, the height of the spray gun 9 is higher than the height of the end of the first pipe 7 located inside the hopper 2, in order to create a potential difference and avoid excessive pressure on the spray gun 9 from affecting the performance.

[0028] In other embodiments, a filter 10 may be provided on the second pipe 8. The filter 10 can further filter solid deposits or other impurities in the pipe, and further prevent these deposits or impurities from clogging the spray gun 9.

[0029] In addition, similarly, a filter element can be provided at the end of the first pipe 7 located in the hopper 2, which can further prevent the intake of solid sediments or other solid impurities at the source.

[0030] Preferably, there is a gap between the opening at the top of the hopper 2 and the first pipe 7, in order to ensure that the inside of the hopper 2 is connected to the outside atmosphere, so as to avoid the formation of negative pressure during the process of the pump body 4 sucking up materials, or the excessive pressure inside the hopper 2 during the process of adding materials into the hopper 2.

[0031] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
