Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a steel pipe surface sandblasting treatment device. Background Technology

[0002] Sandblasting is a surface treatment process that aims to subject the surface of a material or component to rapid and uniform friction, thereby achieving effects such as surface cleanliness, increased surface friction, uniform and reduced reflectivity, and transformation from transparent to semi-transparent. The process involves selecting quartz sand of suitable particle size and using compressed air at appropriate pressure to spray the sand particles onto the material surface. Steel pipes are widely used steel structural components, and during the production process, they often require sandblasting to remove rust spots, enhance the adhesion between the steel pipe surface and the coating, and facilitate the flow of the coating.

[0003] A search revealed that patent document CN209793498U discloses a steel pipe sandblasting and polishing device, comprising a frame, a housing, a control panel, an observation window, a sand collection bin, a base plate, an upper support, a lower support, a sandblasting mechanism, a polishing mechanism, a carrier plate, and a clamping mechanism. The housing is mounted on the frame; the control panel is located on the upper front side of the housing; the observation window is located in the middle of the housing; a base plate is located on the inner side of the rear panel of the housing; the upper support is fixedly connected to the upper part of the base plate; the lower support is fixedly connected to the lower part of the base plate; the sandblasting mechanism is fixedly connected to the upper support; the polishing mechanism is fixedly connected to the lower support; the carrier plate is located in the middle of the base plate and is horizontally positioned; the clamping mechanism is fixedly mounted on the carrier plate.

[0004] However, this sandblasting device can only sandblast the steel pipe from the top and bottom during use, and the sandblasting effect on the front and back sides of the steel pipe is poor. Because of the clamping mechanism, the processing surface of the steel pipe needs to be frequently adjusted to achieve full sandblasting, resulting in low sandblasting efficiency. Therefore, a steel pipe surface sandblasting treatment device is proposed to solve the problems mentioned above. Utility Model Content

[0012] Furthermore, an observation window is provided on the outer wall of the sandblasting box, and a conical discharge hopper is provided at the bottom of the sandblasting box.

[0013] Furthermore, connecting blocks are fixedly connected to both sides of the mounting plate, and a shaft is fixedly connected to the top of the connecting block.

[0022] 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.

[0023] Please see Figures 1 to 4 This embodiment of a steel pipe surface sandblasting treatment device includes a sandblasting box 1, a sandblasting mechanism 3 on the sandblasting box 1, and a sand blasting mechanism 3 including a sand tank 301 fixedly installed on the top of the sandblasting box 1. A control valve 302 is fixedly installed on the outer wall of the sand tank 301. A connecting pipe 303 extending into the sandblasting box 1 is installed at the output end of the control valve 302. A sand pipe 304 is connected to the end of the connecting pipe 303 away from the control valve 302. A plurality of nozzles 305 are provided at the bottom of the sand pipe 304.

[0024] It should be noted that two mounting plates 306 are fixedly connected to the outer wall of the sandblasting pipe 304, and the mounting plates 306 are fixedly connected to the inner top wall of the sandblasting box 1.

[0025] The sandblasting box 1 has symmetrical openings 2 on both sides. The openings 2 are lower than the nozzle 305. Support components 4 are provided on the lower side of the openings 2 on both sides, and transmission components 6 are provided on the upper side of the openings 2 on both sides.

[0026] In this embodiment, the support assembly 4 includes a support plate 401 fixedly installed on the lower side wall of the sandblasting box 1, and two pulleys 402 arranged side by side are rotatably installed on the top of the support plate 401.

[0027] In this embodiment, the transmission assembly 6 includes a fixing plate 601 fixedly installed on the upper side wall of the sandblasting box 1. A cylinder 602 is fixedly installed on the top of the fixing plate 601. An mounting plate 603 is fixedly installed on the output shaft of the cylinder 602. A motor 604 is fixedly installed on the outer wall of the mounting plate 603. A friction wheel 605 is fixedly installed on the output shaft of the motor 604. The friction wheel 605 can be driven to rotate by the motor 604.

[0028] It is understandable that the height of the mounting plate 603 can be adjusted by driving the cylinder 602, thereby adjusting the height of the friction wheel 605 and ensuring stable contact between the friction wheel 605 and the outer wall of the steel pipe 5.

[0029] It should be noted that connecting blocks 606 are fixedly connected to both symmetrical sides of the mounting plate 603. A shaft 607 is fixedly connected to the top of the connecting blocks 606. The shaft 607 movably passes through the top of the fixing plate 601. A spring 608 is provided between the fixing plate 601 and the connecting blocks 606. The spring 608 is sleeved on the outer wall of the shaft 607. In addition, a slider 609 is fixedly connected to the outer wall of the connecting blocks 606. A guide rail 610 is fixedly installed at the bottom of the fixing plate 601. The slider 609 is slidably installed on the outside of the guide rail 610. Through the cooperation of the shaft 607, the spring 608, the slider 609 and the guide rail 610, the mounting plate 603 can be stably guided, improving the stability of the structure.

[0030] In this case, a steel pipe 5 is installed through two pipe openings 2 inside the sandblasting box 1. The bottom wall of the steel pipe 5 is in contact with the outer wall of the pulley 402. The pulley 402 facilitates the rotational support of the steel pipe 5. The top wall of the steel pipe 5 corresponds to the friction wheel 605. When the friction wheel 605 is in contact with the outer wall of the steel pipe 5, the friction wheel 605 rotates and drives the steel pipe 5 to rotate through friction.

[0031] It should be added that an observation window 7 is provided on the outer wall of the sandblasting box 1 to facilitate the staff to observe the inside of the sandblasting box 1. A conical discharge hopper is also provided at the bottom of the sandblasting box 1, and a collection box can be placed at the bottom of the conical discharge hopper to facilitate the collection of waste materials.

[0032] The working principle of the above embodiments is as follows:

[0033] In use, the steel pipe 5 is inserted into the sandblasting box 1 through the two pipe openings 2. The steel pipe 5 is placed between the two pulleys 402 on the support plate 401. The cylinder 602 is started to drive the mounting plate 603 to move downward, so that the friction wheel 605 comes into contact with the surface of the steel pipe 5. With the cooperation of the friction wheel 605 and the two pulleys 402, the steel pipe 5 is clamped. The control valve 302 is opened, and the sand tank 301 sprays sand particles onto the surface of the steel pipe 5 through the connecting pipe 303, sand pipe 304 and nozzle 305. During the sandblasting process, the motor 604 is started to drive the friction wheel 605 to rotate. The friction wheel 605 drives the steel pipe 5 to rotate through friction, so that the nozzle 305 can sandblast the surface of the steel pipe 5.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
