Description

Technical Field

[0001] The utility model provides an iron scrap cleaning device for PC steel bar production, belonging to the technical field of PC steel bar production. Background Art

[0002] PC steel bar is a kind of steel bar used in prestressed concrete structures. PC steel bar has the advantages of high strength, good prestressing effect, material saving, convenient construction, corrosion resistance and environmental sustainability. It is widely used in concrete structures such as bridges, high-rise buildings, and water conservancy projects. The production process of PC steel bar often includes raw material preparation, raw material cutting, steel bar forming, tensile prestressing treatment, and rust prevention treatment.

[0003] During the process of cutting and other processing, the steel rod often produces iron filings, which affects the production quality of the PC steel rod, so the steel rod needs to be cleaned. One of the better ways is to use water flushing. The water combined with the impact force of the water can fully clear the iron filings on the surface of the steel rod, including those embedded in the grooves of the steel rod. However, when flushing the steel rod with water at a higher pressure, although the cleaning effect can be better, the impact force of the water on the steel rod will also affect the stability of the steel rod, causing the steel rod to move and affecting the cleaning effect. Therefore, there is a need for an iron filing cleaning device that is easy to stabilize the position of the steel rod and can achieve a good cleaning effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is that when high-pressure water is used to clean the iron filings of a steel rod, the impact force of the water will affect the stability of the steel rod, causing the steel rod to move, thereby affecting the cleaning effect.

[0005] In order to solve the above-mentioned problems, the utility model proposes the following technical solutions: a chip cleaning device for PC steel rod production, comprising a support seat, a lifting box and a fixed positioning cylinder are fixedly connected to the support seat, a steel rod body is vertically placed in the fixed positioning cylinder; a guide groove is provided on one side of the lifting box, a connecting rod is provided in the guide groove for sliding up and down, a movable positioning ring is fixedly connected to the end of the connecting rod; the movable positioning ring is sleeved on the steel rod body, and an annular cleaning pipe is provided below the movable positioning ring; an annular distributed cleaning nozzle corresponding to the steel rod body is provided below the annular cleaning pipe; a water storage tank is provided in the support seat, a reflux pump is provided in the water storage tank; a water outlet hose is connected to the working end of the reflux pump, and the water outlet hose is connected to the annular cleaning pipe.

[0006] As an improvement, the center of the fixed positioning cylinder corresponds to the center of the movable positioning ring.

[0007] As an improvement, a motor is arranged in the lifting box, and a lead screw is fixedly connected to the output shaft of the motor; a lifting plate is threadedly connected to the lead screw, and the lifting plate is fixedly connected to the connecting rod.

[0008] As an improvement, a water retaining frame is fixedly provided on the support seat, and the fixed positioning cylinder is located in the water retaining frame; a drainage hole connected to the water storage tank is opened at the bottom of the water retaining frame, and the height of the water retaining frame is higher than the height of the fixed positioning cylinder.

[0009] As an improvement, a support plate is fixedly arranged in the water storage tank, a filter screen is arranged above the support plate, and a water permeable hole is opened in the support plate.

[0010] As an improvement, a water-spreading hole is provided at the bottom of the fixed positioning cylinder, and the water-spreading hole is communicated with the water storage tank.

[0011] Beneficial effects of the utility model:

[0012] A fixed positioning cylinder is fixedly connected to the support seat, and a movable positioning ring is fixedly connected to the end of the connecting rod. When installing the steel rod, just put the steel rod in the fixed positioning cylinder, and then put the movable positioning ring on the steel rod. The installation is simple and fast, and the positioning of the steel rod can be quickly completed. When the steel rod is flushed with high-pressure water, it can be ensured that the steel rod will not move.

[0013] The movable positioning ring is set to slide and can be put on steel bars of different heights. The cleaning nozzles distributed in an annular manner can clean the steel bars more comprehensively. At the same time, the cleaning nozzles distributed in an annular manner can generate impact forces in all directions of the steel plate, so that the impact forces offset each other and increase the stability of the steel bars.

[0014] At the same time, an annular cleaning pipe is arranged under the movable positioning ring, which can rise and fall with the movable positioning ring. The annular cleaning pipe can be driven to slide downward by controlling the movable positioning ring to slide downward, so that the annular cleaning pipe can clean the entire steel pipe.

The center of the fixed positioning cylinder 11 corresponds to the center of the movable positioning ring 5.

[0023] The steel rod body 8 is arranged vertically, and the fixed positioning tube 11 and the movable positioning ring 5 are arranged at the same time, so that the steel rod body 8 can be quickly limited conveniently to avoid the movement of the steel rod body 8 under the impact of water.

[0024] A motor 13 is arranged in the lifting box 2 , and a screw rod 14 is fixedly connected to the output shaft of the motor 13 ; a lifting plate 15 is threadedly connected to the screw rod 14 , and the lifting plate 15 is fixedly connected to the connecting rod 4 .

[0025] The setting of the guide groove 3 and the connecting rod 4 can limit the rotation of the lifting plate 15, thereby converting the rotation of the screw rod 14 into the movement of the lifting plate 15, and transmitting the movement to the movable positioning ring 5 through the connecting rod 4, thereby achieving the limitation of steel bars at different heights.

[0026] A water retaining frame 9 is fixedly provided on the support seat 1 , and a fixed positioning cylinder 11 is located in the water retaining frame 9 ; a drainage hole 12 connected to the water storage tank 20 is opened at the bottom of the water retaining frame 9 , and the height of the water retaining frame 9 is higher than that of the fixed positioning cylinder 11 .

[0030] Principle of the utility model

[0031] When using the present application to clean the PC steel bar, start the motor 13, so that the movable positioning ring 5 slides downward under the drive of the lifting plate 15 and the connecting rod 4, until the movable positioning ring 5 is at a position corresponding to the height of the steel bar body 8 to be cleaned; pass the PC steel bar through the movable positioning ring 5 and place it in the fixed positioning cylinder 11. At this time, the steel bar body 8 is completely located in the movable positioning ring 5 and the fixed positioning cylinder 11, which can ensure a good positioning effect, start the reflux pump 18, so that the water in the water tank 20 flows into the annular cleaning pipe 6 through the outlet pipe, and then sprays out from the cleaning nozzle 7 to clean the steel bar. The ring-shaped cleaning nozzle 7 can clean the steel bar body 8 in all aspects, and the ring-shaped cleaning nozzle 7 can generate force around the steel bar body 8, so that the impact force offsets each other, increasing the stability of the steel bar.

[0032] At the same time, the motor 13 can be controlled to move the movable positioning ring 5 and the annular cleaning tube 6 downward, so as to further comprehensively clean the length direction of the steel bar body 8. However, it is necessary to try not to move the movable positioning ring 5 too far downward, so as not to affect the positioning stability of the steel bar body 8. At the same time, for the part where the lower end of the steel bar body 8 is inserted into the fixed positioning cylinder 11, the steel bar body 8 can be turned upside down and rinsed twice to achieve a comprehensive cleaning effect.

[0033] The cleaned waste water enters the water storage tank 20 through the water diffusing holes 21 and the drainage holes 12, and enters the bottom of the water storage tank 20 after being filtered by the filter screen 16, so as to achieve the effect of water recycling and save water resources.
