Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline descaling, in particular to a pipeline dirt cleaning tool. Background Art
[0002] The Venturi effect, also known as the Venturi effect, is a physical phenomenon discovered by Italian physicist Venturi. The principle is that when a confined fluid passes through a reduced flow cross-section, the fluid velocity increases and a partial vacuum phenomenon is generated. This phenomenon is mainly based on Bernoulli's principle, that is, the increase in fluid velocity is accompanied by a decrease in fluid pressure. In practical applications, the Venturi effect can be used to make a Venturi tube to measure flow or provide external suction by controlling the flow velocity and pressure difference.
[0003] The venturi tube is mainly composed of the inlet section, the contraction section, the throat and the diffusion section. This special structure makes the venturi tube in the chemical production process often cause scaling and blockage and safety problems, so the frequency of descaling and cleaning is very high.
[0004] At present, physical cleaning methods are often used to descale the inside of the Venturi tube, but physical descaling has the following problems:
[0005] 1. Physical cleaning (such as repeated knocking) can easily damage the anti-corrosion lining inside the Venturi tube;
[0006] 2. Physical cleaning cannot effectively remove debris from the inner wall of the Venturi tube, and if it is not cleaned thoroughly, the service life will be affected. Utility Model Content

[0039] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.
[0040] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0041] See also Figure 1 and Figure 2 As shown, the utility model provides a pipeline dirt cleaning tool, comprising:
[0042] A liquid storage pot 1, in which descaling liquid is stored;
[0043] The hollow spray rod 2 is sealed and connected to the top outlet of the liquid storage pot 1;
[0044] The nozzle 3 is fixedly connected to the top of the hollow spray rod 2;
[0045] Brushes 4 are evenly distributed around the nozzle 3;
[0046] A liquid guide tube 5, one end of which is arranged at the bottom of the liquid storage pot 1, and the other end of which passes through the hollow spray rod 2 and is connected to the spray head 3; and
[0047] The air pump 6 is fixedly mounted on the outer wall of the liquid storage pot 1;
[0048] Among them, the outlet of the air pump 6 extends into the interior of the liquid storage pot 1 to pump gas into the latter, which is used to increase the pressure inside the liquid storage pot 1 so that the descaling liquid enters the liquid guide tube 5 to achieve liquid filling; a switch valve 21 connected to the liquid guide tube 5 is provided on the hollow spray rod 2 to control the on-off of the liquid guide tube 5.
[0049] During operation, the operator extends the nozzle 3 of the tool into the pipeline, presses the switch valve 21 to open the liquid guide tube 5, and then turns on the air pump 6 to pump gas into the liquid storage pot 1 to increase the pressure inside the liquid storage pot 1. At this time, the descaling liquid enters the liquid guide tube 5 under pressure and flows to the nozzle 3. The nozzle 3 sprays the descaling liquid onto the inner wall of the pipeline (such as the throat of the Venturi tube) to react with the attached dirt with acid and alkali neutralization. At the same time, the liquid storage pot 1 is rotated, and the loose dirt is scraped by the brush 4 to complete the dirt cleaning; after the descaling liquid stored in the liquid storage pot 1 is completely sprayed out, the gas continued to be pumped in by the air pump 6 can be sprayed out from the nozzle 3 to purge and dry the inner wall of the pipeline. That is to say, this tool can efficiently and thoroughly clean the debris on the inner wall of the pipe by combining the chemical reaction of the descaling liquid sprayed out by the nozzle 3 with the dirt and the physical scraping of the brush 4. The brush 4 can also reduce the damage to the anti-corrosion lining inside the pipe, thereby extending the service life of the pipe after the dirt is cleaned.
[0050] See also Figure 2 As shown, the nozzle 3 is cylindrical, and a plurality of nozzles 31 are provided on its circumferential side. The nozzles 31 and the root of the brush 4 are staggered to reduce the obstruction of the descaling liquid. When the pressure inside the liquid storage pot 1 increases, the descaling liquid is sprayed from the plurality of nozzles 31 to the inner wall of the pipe through the liquid guide pipe 5.
[0051] The nozzle 3 is provided with a liquid storage chamber 32 connected to the nozzle 31 and the liquid conduit 5, respectively, for caching part of the descaling liquid. When the pressure inside the liquid storage pot 1 increases, the descaling liquid cached in the liquid storage chamber 32 is squeezed by the descaling liquid from the liquid conduit 5 and ejected from the nozzle 31.
[0052] In this embodiment, the nozzle 3 is made of stainless steel and the surface is sprayed with PTFE coating. Stainless steel has strong corrosion resistance, and the PTFE coating can further improve its corrosion resistance, that is, effectively prolong the service life of the nozzle 3.
[0053] The inlet of the liquid conduit 5 (located at one end of the bottom of the liquid storage pot 1) is provided with a filter screen 51 for removing impurities in the descaling liquid.
[0054] According to the chemical characteristics of the impurities and dirt on the inner wall of the pipeline, a descaling liquid with a relatively high pH value can be selected. In this embodiment, the descaling liquid is weakly acidic.
[0055] In order to prevent the descaling liquid in the liquid storage pot 1 from flowing back into the air pump 6 , a one-way valve 61 is provided at the outlet of the air pump 6 .
[0056] In this embodiment, the switch valve 21 is a handle-type switch valve. During use, repeatedly pressing the switch valve 21 can control the flow of the descaling liquid in the liquid guide tube 5; the liquid guide tube 5 is a pressure-resistant and corrosion-resistant antifreeze rubber tube with a certain elasticity.
[0057] A liquid replenishing pipe 11 with a valve is provided on the outer wall of the liquid storage pot 1 opposite to the air pump 6. The liquid replenishing pipe 11 is connected to the inside of the liquid storage pot 1 and is used to replenish the descaling liquid. When the descaling liquid is used up, the valve on the liquid replenishing pipe 11 and the switch valve 21 are opened to replenish the descaling liquid into the liquid storage pot 1.
[0058] In order to facilitate the operator to rotate the liquid storage pot 1, the outer bottom of the liquid storage pot 1 is provided with a handle 12.
[0059] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
