Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical and food material production equipment, specifically a material conveying pipeline cleaning device. Background Technology

[0002] In the pharmaceutical and food production industries, pipelines are commonly used to transport materials. These pipelines are called material conveying pipelines, and the materials are transported by the airflow passing through them. During the material transport process, material inevitably remains on the inner walls of the pipeline. Over time, this residue can accumulate into clumps or blocks, affecting transport efficiency, causing blockages, and leading to cross-contamination between different materials. Therefore, regular pipeline cleaning is necessary.

[0003] Typically, material conveying pipelines are designed to slope upwards from the feed side. Taking advantage of this, a cleaning port is usually installed at the end of the pipeline near the feed side, with a removable plug. During material conveying, the plug seals the cleaning port; during cleaning, the plug is removed, and a water gun is used to rinse the inner wall of the pipeline. This cleaning method not only uses a large amount of water, but also has poor cleaning effectiveness for longer pipelines because the water flow rate decreases with increasing pipeline length. Utility Model Content

[0004] The purpose of this invention is to overcome the defects and deficiencies of the existing technology and provide a material conveying pipeline cleaning device. During cleaning, the cleaning mechanism is pushed out from the inside of the extension pipe section and can travel along the inner wall of the conveying pipeline to clean the inner wall of the conveying pipeline, thereby saving water and improving the cleaning effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A material conveying pipeline cleaning device includes a material conveying pipeline, wherein a cleaning interface is provided at one end near the feed side of the conveying pipeline, characterized in that: the cleaning interface is detachably connected to an extension pipe section communicating with the interior of the conveying pipeline, a drain outlet is provided at the rear end of the bottom of the extension pipe section, and a cleaning mechanism is provided inside the extension pipe section. The cleaning mechanism extends out from the interior of the extension pipe section and travels along the inner wall of the material conveying pipeline for cleaning the material conveying pipeline.

[0007] Furthermore, the cleaning mechanism includes a water supply pipe, a nozzle is fixedly connected to the front end of the water supply pipe, a collar is fixedly fitted on the front section of the water supply pipe, and several elastic telescopic rods extending radially along the collar are fixedly connected to the outer wall of the collar, with a roller installed at the end of each elastic telescopic rod.

[0008] Furthermore, the water supply pipe is a semi-flexible pipe.

[0009] Furthermore, a sealing plate is fixedly connected to the rear end of the extended pipe section. The sealing plate has a through hole, through which the rear end of the water supply pipe is led out and connected to an external water pump.

[0010] Furthermore, a guide for forward conveying the water pipe and a hose reel for retracting the water pipe are sequentially provided behind the extended pipe section.

[0011] Furthermore, the guide includes an inverted bracket, on which two guide wheels are rotatably mounted on the upper and lower inner walls. The four guide wheels are arranged in pairs facing each other, and each pair of facing guide wheels is coaxially mounted with a handwheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention allows for the detachable connection of an extension pipe section to the cleaning interface of an existing material conveying pipeline, and the installation of a cleaning mechanism inside the extension pipe section. During cleaning, the cleaning mechanism is pushed out from inside the extension pipe section and can travel along the inner wall of the conveying pipeline to clean the inner wall of the pipeline. This not only saves water consumption but also effectively improves the cleaning effect. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] See Figure 1 ,2 A material conveying pipeline cleaning device includes a material conveying pipeline 1. The conveying pipeline 1 has a cleaning interface 3 at one end near its feed side 2. The cleaning interface 3 is detachably connected to an extension pipe section 5 that communicates with the interior of the conveying pipeline 1 via a quick pipe connector 4. The rear end of the bottom of the extension pipe section 5 has a drain outlet 6. The interior of the extension pipe section 5 has a cleaning mechanism 7. The cleaning mechanism 7 extends out from the interior of the extension pipe section 5 and travels along the inner wall of the material conveying pipeline 1 for cleaning the material conveying pipeline 1.

[0021] In this embodiment, the cleaning mechanism 7 includes a water supply pipe 71, a nozzle 72 is fixedly connected to the front end of the water supply pipe 71, a collar 73 is fixedly fitted on the front section of the water supply pipe 71, and four elastic telescopic rods 74 extending radially along the collar 73 are fixedly connected to the outer wall of the collar 73, and a roller 75 is installed at the end of each elastic telescopic rod 74.

[0022] In this embodiment, the water supply pipe 71 is a semi-flexible pipe.

[0023] It should be noted that, based on existing technology, semi-flexible pipe is a type of pipe that falls between flexible and rigid pipe. It has a certain degree of flexibility and strength, can adapt to deformation such as bends, and also has high resistance to corrosion, high pressure and high temperature.

[0024] Therefore, when the water pipe 71 (semi-flexible pipe) travels along the bend of the material conveying pipeline 1, the water pipe 71 can bend adaptively without getting tangled; at the same time, each elastic telescopic rod 74 can elastically extend and retract adaptively, traveling inside the material conveying pipeline 1, especially when going through bends (passing through bends), so that the water pipe 71 and the nozzle 72 always remain coaxial with the material conveying pipeline 1, which can not only pass smoothly, but also ensure the cleaning effect.

[0025] In this embodiment, a sealing plate 8 is fixedly connected to the rear end of the extension pipe section 5. The sealing plate 8 is provided with a through hole. The rear end of the water supply pipe 71 passes through the through hole and is led out and connected to an external water pump (not shown in the figure) to supply cleaning water with a certain pressure.

[0026] The following description, in conjunction with the accompanying drawings, further illustrates this embodiment:

[0027] When conveying materials, the plug seals the cleaning interface 3 to prevent the normal conveying of materials from being affected.

[0028] During cleaning, first remove the plug, connect the extension pipe section 5 to the cleaning interface 3 through the quick pipe connector 4, and connect it to the inside of the delivery pipe 1.

[0029] Then, with the help of external force, the water pipe 71 is pushed out from the inside of the extension pipe section 5, so that the roller 75 moves along the inner wall of the conveying pipe 1. The water pump pumps the cleaning water into the water pipe 71 under pressure, and finally sprays it out through the nozzle 72 to clean the inner wall of the material conveying pipe 1.

[0030] During the cleaning process, since the material conveying pipe 1 is inclined upward from its feed side, the sewage will flow backward along the inner wall of the material conveying pipe 1 and eventually be discharged through the drain outlet 6.

[0031] After cleaning, first pull back the water supply pipe 71 and let it retract into the extension pipe section 5.

[0032] Then, compressed air is introduced into the water supply pipe 71 and the water supply pipe 71 is moved back and forth. The compressed air is discharged through the nozzle 72 and dries the inner wall of the material conveying pipe 1.

[0033] Then, remove extension pipe section 5 and reinstall the plug.

[0034] Example 2

[0035] See Figure 3 , 4 Behind the extension pipe section 5, there are sequentially arranged a guide 9 for forward transmission of the water pipe 71 and a hose reel 10 for retracting and extending the water pipe 71.

[0036] Specifically, the guide 9 includes an inverted bracket 91, on which two guide wheels 92 are rotatably mounted on the upper and lower inner walls. The four guide wheels 92 are arranged in pairs facing each other, and a handwheel 93 is coaxially mounted on each of the two opposing guide wheels 92.

[0037] This embodiment is mainly applicable to material conveying pipelines 1 that are relatively long.

[0038] During cleaning, the hose reel 10 rotates to unwind the hose, while the handwheel 93 is turned to move the water pipe 71 forward, thus replacing manual pushing of the water pipe 71 and achieving a labor-saving and efficient effect.

[0039] After cleaning, the hose reel 10 rotates in the opposite direction to rewind and pull back the water pipe 71, causing it to retract into the extension pipe section 5.

[0040] The other components and structures in this example are the same as in Example 1, and will not be described again here.

[0041] It should be noted that, in order to accommodate a certain height above the ground for the material conveying pipeline 1, and also to better convey the water pipe 71, the extension pipe section 5 and the guide 9 can be set on the same workbench.

[0042] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0043] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
