During the rust removal process, the steel grit collides with the rust on the surface of the steel pipe, and the rust attached to the surface of the steel pipe turns into powder, and the dust and other impurities attached to the surface of the steel pipe also fall off the steel pipe. At this time, the rust, dust and other impurities exist in the cavity of the rust remover in the form of dust, causing the inner cavity of the rust remover to be filled with various dusts. When the rust removal is completed, if the maintenance personnel need to inspect the inside of the rust remover, various dusts enter the human body with the maintenance personnel's breathing, affecting the respiratory system and lungs; at the same time, the steel grit is reused in the rust removal process. A large amount of dust is mixed in the steel grit after the last rust removal work. When the steel grit is used again for the second rust removal work, the concentration of dust in the rust remover is increased. As time goes on, the dust will slowly settle inside the rust remover, and in severe cases, it will block the steel grit outlet.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0021] Please see Figures 1 to 3 A dust removal device for a rust remover includes a primary dust removal component 10, wherein the primary dust removal component 10 includes a dust extraction pipe 101, an opening and closing member 102, a power member 103 and a water tank 104, one end of the dust extraction pipe 101 is communicated with an internal cavity of the rust remover, the opening and closing member 102 is arranged on the dust extraction pipe 101, and the opening and closing member 102 is in an open or closed state, the power member 103 is arranged on the dust extraction pipe 101, and the other end of the dust extraction pipe 101 is connected to the water tank 104.

[0022] The first-level dust removal component 10 is used to remove dust in the rust remover. When it is used, the opening and closing member 102 is used to connect or close the dust extraction pipe 101 and the internal cavity of the rust remover. In the first state, the opening and closing member 102 is used to close the connection between the dust extraction pipe 101 and the internal cavity of the rust remover, that is, when the rust remover is working, the opening and closing member 102 is in a closed state. In this state, the first-level dust removal component 10 does not perform dust extraction. At this time, the internal cavity of the rust remover is a closed cavity, which avoids affecting the sealing of the internal cavity of the rust remover. The dust extraction pipe 101 is not connected to the internal cavity of the rust remover, which also avoids high-speed moving steel sand from entering the dust extraction pipe 101.

[0023] In the second state, the opening and closing member 102 is used to connect the dust extraction pipe 101 with the internal cavity of the rust remover, that is, when the rust remover is stopped, the opening and closing member 102 is in an open state. In this state, the primary dust removal component 10 performs dust extraction. At this time, the internal cavity of the rust remover is connected with the dust extraction pipe 101 and the internal cavity of the rust remover to extract the dust in the internal cavity of the rust remover, and at the same time, it is avoided that the steel sand at the bottom of the rust remover is sucked out by the suction force when the dust is extracted. under the action of, the dust is sucked into the dust extraction pipe 101, thereby reducing the waste of steel sand; when the dust extraction pipe 101 is extracting dust, the power part 103 increases the power of dust extraction for the dust extraction pipe 101. After the dust inside the rust remover is extracted, the outlet end of the dust extraction pipe 101 is directly connected to the water tank 104. At this time, the extracted dust is adsorbed by the water in the water tank 104 and precipitated into the water, thereby achieving the purpose of removing dust in the rust remover. At the same time, the adsorption of water is utilized to simplify the dust removal steps.

[0024] In another embodiment, one end of the dust extraction pipe 101 extends into the inner cavity of the rust remover, and the opening and closing member 102 is disposed on the dust extraction pipe 101 and is located between the power member 103 and the rust remover.

[0025] At this time, the opening and closing member 102 is arranged on the dust extraction pipe 101 and does not come into contact with the rust remover. At this time, the opening and closing member 102 can be understood as a valve.

[0026] In a specific embodiment, the opening and closing piece 102 is arranged on the side wall of the rust remover and is connected to the internal cavity of the rust remover. One end of the dust extraction pipe 101 is connected to the opening and closing piece 102 , and the opening and closing piece 102 is located at one end of the dust extraction pipe 101 .

[0027] In this embodiment, one end of the opening and closing member 102 is connected to the side wall of the rust remover, and the other end is connected to the dust extraction pipe, that is, the opening and closing member 102 is arranged close to the side wall of the rust remover.

[0028] In a preferred embodiment, the opening and closing member 102 includes a fixed plate 1021, an opening and closing baffle 1022 and a buckle 1023. The fixed plate 1021 is provided with a slide groove and a through hole. The fixed plate 1021 is arranged on one side of the rust remover, and the through hole is communicated with the internal cavity of the rust remover. The buckle 1023 is arranged on the side of the through hole away from the rust remover. One end of the dust extraction pipe 101 is detachably connected to the buckle 1023. The opening and closing baffle 1022 slides with the slide groove. In cooperation, the penetration direction of the through hole is perpendicular to the sliding direction of the opening and closing baffle 1022, and the opening and closing baffle 1022 slides between a first position and a second position. In the first position, the opening and closing baffle 1022 blocks the through hole, and in the second position, the opening and closing baffle 1022 avoids the through hole. The buckle 1023 is arranged between the dust extraction pipe 101 and the fixed plate 1021, and the buckle 1023 can be snapped onto the fixed plate 1021 and communicated with the internal cavity of the rust remover.

[0029] The fixed plate 1021 is arranged on one side of the rust remover, and the fixed plate 1021 is provided with a slide groove, the opening and closing baffle 1022 is slidably matched with the slide groove, and the opening and closing baffle 1022 can move in the slide groove. When it is used in practice, when dust extraction is required, the opening and closing baffle 1022 can move upward along the slide groove to reach the second position, so that the opening and closing member 102 is in an open state, that is, the opening and closing baffle 1022 is moved from the fixed plate 102 1, but not completely, the opening and closing baffle 1022 only needs to avoid the through hole, so that the dust extraction pipe 101 is connected with the internal cavity of the rust remover. When the dust extraction is finished or the rust remover is working, the opening and closing baffle 1022 can move downward along the slide groove to the first position, so that the opening and closing member 102 is in a closed state, that is, the opening and closing baffle 1022 is inserted into the fixed plate 1021, so that the dust extraction pipe 101 is not connected with the internal cavity of the rust remover. It should be noted that the moving direction of the opening and closing baffle 1022 is perpendicular to the direction of the through hole, that is: the setting direction of the slide groove is perpendicular to the setting direction of the through hole; the buckle 1023 connects the dust extraction pipe 101 and the fixed plate 1021, so that the dust extraction pipe 101 and the fixed plate 1021 can be detachably connected, which is convenient for separating the dust extraction pipe 101 from the rust remover.

[0030] Furthermore, the power component 103 is a fan.

[0031] When the fan is in use, it provides dust extraction power for the dust extraction pipe 101, and uses the motor to rotate the impeller to form a strong airflow to form an air flow difference, such as a suction fan, a high-pressure blower, etc., to extract the dust in the rust remover. In specific usage scenarios, the power component 103 can also be composed of a vacuum pump and a piping system. In different usage scenarios, staff in this technical field can choose a suitable method.

[0032] In a specific embodiment, a secondary dust removal component 20 is also included, and the secondary dust removal component 20 includes a first water tank 201 and a second water tank 202. The first water tank 201 is used to hold steel sand, and a leakage hole 2011 is provided at the bottom of the first water tank 201. The second water tank 202 is used to accommodate the first water tank 201, and the first water tank 201 is suspended in the second water tank 202.

[0033] The secondary dust removal component 20 is used to remove dust from the steel sand to prevent the dust from entering the rust remover for the second time. Since the rust remover uses high-speed steel sand to collide with the steel pipe to remove rust, during the rust removal process, the rust on the surface of the steel pipe and the dust and other impurities attached to the surface of the steel pipe fall off the steel pipe and turn into powder. At this time, part of the dust will be mixed with the steel sand. When these steel sands are used again for rust removal, the dust mixed in the steel sand will enter the cavity inside the rust remover. In order to avoid this situation, the secondary dust removal component 20 is set. After the rust removal is completed, the operator transfers the steel sand into the first water storage tank 201, and then places the first water storage tank 201 in the second water storage tank 202. After that, the operator The operator adds water into the first water tank 201 to rinse the steel sand. A part of the water after cleaning overflows along the leakage hole 2011 and flows into the second water tank 202, and another part of the water flows into the second water tank 202 along the edge of the first water tank 201 (if the water flow is too large, the water cannot all flow out of the leakage hole 2011. At this time, the water will overflow from the first water tank 201 and flow into the second water tank 202). After rinsing the steel sand, the dust in the steel sand is removed. At the same time, when the cleaned steel sand is reused for the second time, it is not necessary to humidify the steel sand, which simplifies the use steps of the steel sand.

[0034] In a specific embodiment, a support column 2021 is disposed at the bottom of the second water storage tank 202 , and the first water storage tank 201 is disposed on the support column 2021 .

[0035] If the first water tank 201 is directly placed in the second water tank 202, when cleaning the steel sand, the first water tank 201 and the steel sand in the first water tank 201 will be submerged in water. At this time, the first water tank 201 and the steel sand in the first water tank 201 need to be taken out from the second water tank 202, and the dust floating on the water surface will come into contact with the uppermost steel sand, which is equivalent to not removing the dust from the steel sand. In order to avoid this drawback, the support column 2021 is provided, and the first water tank 201 is suspended in the second water tank 202 to ensure that the water containing dust no longer comes into contact with the steel sand, thereby achieving the purpose of removing the dust from the steel sand.

[0036] In a preferred embodiment, a liquid pipeline 30 is further included, one end of which is connected to the supernatant outlet of the water tank 104 , and the other end of which is located on the first water storage tank 201 .

[0037] The dust extraction pipe 101 passes the extracted dust into the water tank 104 for dust removal. The dust is adsorbed by the water in the water tank 104 and precipitated into the water. At this time, the upper layer of water in the water tank 104 is clear. By utilizing the liquid pipeline 30, the upper layer of clear liquid in the water tank 104 can be passed into the secondary dust removal component 20 in specific usage scenarios to clean the steel sand containing dust, thereby improving the utilization rate of water.

[0038] What is disclosed above is only the preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and making equivalent changes according to the claims of the present application still fall within the scope covered by the application.
