Description

Technical Field

[0001] The utility model relates to the field of trenchless pipeline repair, and in particular to a convenient cleaning air compressor and trenchless pipeline repair equipment thereof. Background Art

[0002] As cities grow larger, the layout and transportation capacity requirements of urban pipeline networks are becoming increasingly demanding. Pipeline networks themselves also face numerous problems, such as corrosion, scaling, leakage, and damage, as well as the need for repair and replacement of some pipelines at the end of their expected service life. Pipeline network repair technologies are currently divided into two types: trenchless and excavation. Trenchless repair technology greatly reduces the excavation area and workload during pipeline repair, avoids traffic congestion and environmental pollution caused by frequent excavation, landfill, and laying, and reduces the waste of resources caused by excavation. Trenchless repair technology is also becoming increasingly widely used in urban construction. Underground pressureless trenchless folding repair technology offers high repair efficiency, minimal environmental damage, and virtually no road surface recovery time. The folded lining method is also called the tight-fitting lining method. Its working principle is to use the problem pipe as the main carrier, and to pull the lining pipe that has been compressed or pressed into a "C" shape, "U" shape, or other shapes into the original problem pipe by a directional pulling method. Then, through heating, pressurizing, standing, etc., the compressed cross-sectional area is restored to fit the problem pipe, forming a pipe lining that fits tightly with the original pipe.

[0003] During the trenchless pipeline repair construction process mentioned above, the inner liner thermoplastic repair equipment is required to heat and pressurize the inner liner for restoration, and the equipment will use an air compressor, that is, an air compressor. When the air is input, the air compressor will use a filter to filter out debris in the air to reduce damage to the air compressor.

[0004] However, the existing filter devices are generally located inside the equipment and are inconvenient to disassemble and clean, which reduces the maintenance efficiency of the air compressor. For example, an existing air intake filter mechanism for an air compressor includes a filter. The filter is provided with a storage tank, a filter tank and a pressurizing tank from left to right. The top and bottom ends of the pressurizing tank are slidably embedded with pistons, and the top and bottom ends of the pressurizing tank are fixedly connected with electric telescopic rods. A second one-way valve is provided between the storage tank and the filter tank, and a first one-way valve is provided on the air inlet pipe. Although this filter mechanism improves the filtration speed, the filter element mechanism is still located inside the equipment, which is not convenient for disassembly and cleaning, reducing the maintenance efficiency of the air compressor. It is more practical in dust-free environments such as factories or workshops, but cannot be applied to non-excavation repair projects with poor working conditions. Utility Model Content

[0005] The purpose of the utility model is to overcome the problem that the existing air compressor filter components used for non-pipeline repair are inconvenient to disassemble and clean, and to provide a convenient cleaning air compressor and its non-excavation pipeline repair equipment, so that the filter components of the air compressor can be easily disassembled during non-excavation pipeline repair, thereby improving the maintenance efficiency of the air compressor.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] 18. The air filter assembly of claim 17, wherein the air filter is a filter element and a control element.

The second air filter has a first end and a second end. The first air filter has a first end and a second end. The first air filter has a first end and a second end. The first air filter has a first end and a second end. The first air filter has a first end and a second end. The first air filter has a first end and a second end.

[0008] During the operation of the above solution, the air compressor is moved to the construction area and turned on. The filter first uses the filter screen to filter out larger dust particles in the gas, which are then transported to the intake pipe through the vents on the movable plate and finally enter the air compressor body. The air compressor body then compresses the gas. When too much dust accumulates on the filter screen and needs to be cleaned, the drive device is turned on and pushes the movable plate to slide out of the open end of the air intake housing. At this time, workers can remove the filter screen from the movable plate for flushing. Using the drive device to push the movable plate out of the air intake housing and then remove the filter screen for cleaning, this arrangement facilitates the removal and cleaning of the filter, improves the maintenance efficiency of the air compressor, and is suitable for trenchless repair projects with poor working conditions.

When disassembling the threaded connection, the filter can be removed by simply unscrewing the screws with a screwdriver, which is reliable and easy to disassemble. The center of the vent is aligned with the center of the filter, which can maximize the utilization of the filter area, and the filter can be made smaller, making it more convenient to clean.

[0013] Furthermore, a trenchless pipeline repair device includes a base and a universal wheel, wherein the universal wheel is fixedly installed on the bottom surface of the base, and also includes the above-mentioned convenient cleaning air compressor, wherein the convenient cleaning air compressor is fixedly installed on the top surface of the base; the universal wheel is installed on the base to make the movement of the equipment more convenient.
