Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of industrial equipment, specifically relates to a pipeline heat preservation device. BACKGROUND

[0002] The pipeline heat preservation device is a device for reducing heat loss in the pipeline or preventing external heat from entering the pipeline, which is widely used in various pipeline systems that need heat preservation, such as heating, refrigeration, petroleum, chemical industry, etc., to prevent heat loss in the pipeline from entering the external environment and ensure that the temperature of the medium in the pipeline is maintained within the required range.

[0003] According to the search, the publication (announcement) No. CN220102495U discloses a pipeline temperature heat preservation device, which discloses "a pipe body, a fixed frame is fixedly connected to the inner side of the middle part of the pipe body, a rotating shaft is rotatably connected inside the fixed frame, a plurality of fan leaves are fixedly connected to the outer end of the rotating shaft, and a scraper frame technical scheme is fixedly connected to the rear end of the rotating shaft, so that the scraper frame can be rotated to scrape off the dirt adhered to the inside of the pipe body, prevent the pipe body from being blocked by a large amount of dirt accumulation, and achieve the effect of ensuring normal flow of desulfurization waste liquid material";

[0004] Although the design can make the scraper frame rotate to scrape off the dirt adhered to the inside of the pipe body, prevent the pipe body from being blocked by a large amount of dirt accumulation, and achieve the effect of ensuring normal flow of desulfurization waste liquid material, the above-mentioned device lacks efficient self-cleaning function, and only one impeller structure is driven, when a large amount of material flows through the pipeline, dirt, sediments and scale are easily accumulated on the inner wall of the pipeline, which not only reduces the flow efficiency of the pipeline, but also may cause corrosion to the pipeline material, shortens the service life of the pipeline, the dirt and sediments on the inner wall form a heat insulation layer, hinder the heat transfer, cause the heat preservation performance to decline, which means that more energy needs to be consumed to maintain the required temperature in the pipeline, increases the operation cost.

[0005] Therefore, a pipeline heat preservation device is designed to solve the above problems. UTILITY MODEL CONTENTS

[0006] (I) The technical problem solved

[0007] To solve the problems raised in the background art, the utility model provides a pipeline heat preservation device, through the cleaning strip of the cleaning assembly, dirt and deposits on the inner wall of the pipeline body are effectively removed, and the formation of an insulating layer by these impurities is avoided, thereby reducing thermal resistance. The reduction of thermal resistance means that the transfer of heat between the inside and outside of the pipeline is more efficient, the heat preservation effect is improved, and the clean inner wall of the pipeline enables the heat preservation layer to better perform its function. The design purpose of the heat preservation layer is to reduce heat transfer, and the clean inner wall of the pipeline body ensures that the heat transfer between the heat preservation layer and the pipeline is more uniform and efficient, thereby improving the efficiency of the entire heat preservation system. Dirt and deposits may cause damage to the heat preservation layer, such as corrosion or wear. By regularly removing these impurities, the heat preservation layer can be protected from damage, thereby prolonging its service life. The clean inner wall of the pipeline body and the efficient heat preservation layer work together to reduce energy consumption. Since heat transfer is more efficient, the temperature required inside the pipeline body can be more easily maintained, thereby reducing the operating time and energy consumption of the heating or cooling system.

[0022] (III) Beneficial Effects

[0023] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application incorporates a cleaning component that effectively removes dirt and deposits from the inner wall of the pipe body via cleaning strips, preventing these impurities from forming an insulation layer and thus reducing thermal resistance. Reduced thermal resistance means more efficient heat transfer between the inside and outside of the pipe, improving insulation performance. A clean inner pipe wall allows the insulation layer to function better. The insulation layer is designed to reduce heat transfer, while a clean inner pipe wall ensures more uniform and efficient heat transfer between the insulation layer and the pipe, thereby improving the overall efficiency of the insulation system. Dirt and deposits can damage the insulation layer, such as causing corrosion or abrasion. Regularly scraping away these impurities protects the insulation layer from damage, extending its service life. The combined effect of a clean inner pipe wall and an efficient insulation layer reduces energy consumption. Because heat transfer is more efficient, the required temperature inside the pipe body can be more easily maintained, thus reducing the operating time and energy consumption of the heating or cooling system.

[0033] like Figure 1 As shown;

[0034] A pipe insulation device includes a pipe body 1.

[0035] In this implementation plan: Although the design enables the scraper frame to remove debris adhering to the inside of the pipe when it rotates, preventing the pipe from clogging due to the accumulation of debris, thereby ensuring the normal flow of desulfurization waste liquid, the above device lacks an efficient self-cleaning function. It is driven by only an impeller structure. When a large amount of material flows through the pipeline, dirt, deposits, and scale easily accumulate on the inner wall of the pipeline. These dirt not only reduce the flow efficiency of the pipeline but may also corrode the pipeline material, shortening the service life of the pipeline. The dirt and deposits on the inner wall will form a heat insulation layer, hindering the transfer of heat and causing a decrease in heat preservation performance. This means that more energy needs to be consumed to maintain the required temperature inside the pipeline, increasing operating costs. To solve this technical problem, a cleaning component 2 is added on this basis.

The reduction of thermal resistance means that the heat transfer between the inside and outside of the pipeline is more efficient, and the heat preservation effect is improved. The clean inner wall of the pipeline body 1 enables the insulation layer to better play its role. The purpose of the design of the insulation layer is to reduce heat transfer, and the clean inner wall of the pipeline body 1 ensures that the heat transfer between the insulation layer and the pipeline is more uniform and efficient, thereby improving the efficiency of the entire insulation system.

[0046] Working principle: when the user uses the device, the device can be placed inside the designated pipeline, at this time the user can move the top plate 210 inside the fixed plate 28, while releasing the spring 29, the end of the top plate 210 outside abuts against the inner wall surface of the pipeline body 1, after the position is appropriate, the user can rotate the nut 212, increase the pressure of the bolt 213 and the nut 212 on the fixed plate 28, and then the position of the connecting plate 21 can be fixed, at this time the chemical liquid in the pipeline body 1 flows under the action of liquid flow force, the impeller 22 rotates, two adjacent impellers 22 in four adjacent impellers 22 are a group, two groups of impellers 22 are oppositely arranged, which can drive the impeller 22 to rotate, the impeller 22 rotates at the same time, which can drive the gear 24 meshing with it to rotate, the gear 24 rotates at the same time, which can drive the scraper 25 to rotate, and the cleaning strip 26 can clean the inner wall surface of the pipeline body 1, the through slot 27 ensures that most of the liquid can pass through the scraper 25, and the cleaning strip 26 of the cleaning assembly 2 can effectively remove the dirt and deposits on the inner wall of the pipeline body 1, so as to avoid the formation of thermal insulation layer, thereby reducing the thermal resistance.

Its unique shape makes the cleaning strip 26 have a larger contact area and stronger scraping force during scraping, thereby ensuring the cleanliness of the inner wall of the pipeline body 1. The anti-skid block 211 has good elasticity and sealing performance, and can tightly fit the surface of the pipeline body 1. This is particularly important for occasions where the liquid pressure in the pipeline needs to be maintained or external impurities need to be prevented from entering.
