Description

Technical Field

[0001] The present application relates to the technical field of steel shot recovery and processing, and specifically discloses a steel shot recovery device. Background Art

[0002] Steel shot is a small spherical product made of carbon steel material with high density, hardness and good wear resistance. It is widely used in many industries, such as construction engineering, manufacturing, aerospace, automotive industry, etc.

[0003] Steel shot recycling is the process of recycling used steel shots and applying them again to equipment with relatively low precision requirements after processing. Compared with new steel shots, recycled steel shots have obvious price advantages.

[0004] In the recycling of steel shots, process flows such as steel shot collection, impurity separation, and heat treatment are usually involved. For the impurity separation, since the dust content of the steel shots after use is relatively high, the vibration cleaning method will lead to a relatively harsh working environment. Therefore, it is currently more common to use a negative pressure fan to adsorb impurities. However, due to the small size and overall mass of the steel shots themselves, the impurity cleaning effect is poor when a low-power negative pressure fan is used. When a high-power negative pressure fan is used to remove impurities from the steel shots, the steel shots themselves are easily attached to the filter surface by suction, thereby affecting the normal conduction of air and impurities, and further resulting in the need to frequently clean the filter when separating impurities from the steel shots. Therefore, in view of this, the inventor provides a steel shot recycling device to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that in the traditional recycling of steel shots, when a negative pressure fan is used to separate impurities from steel shots, the steel shots themselves are easily attached to the surface of the filter due to suction, affecting the normal conduction of air and impurities and causing frequent cleaning of the filter.

[0006] In order to achieve the above object, the basic scheme of the present invention provides a steel shot recovery device, comprising:

[0007] Dust removal box, with a feed hopper on the top and a discharge port at the bottom;

[0008] A material tray rotates in the dust removal box and is connected to the feed hopper and the discharge pipe, and a plurality of through holes are provided at the peripheral end of the material tray;

[0009] The driving assembly comprises an air guide ring cavity provided at the top of the dust removal box, a rotating ring rotatably connected in the rotating ring cavity and connected to the material tray, blades provided on the rotating ring, and an air flow duct connected to the air guide ring cavity, wherein the bottom of the air guide ring cavity on one side away from the air flow duct is connected to the inside of the material tray, and the side wall of the material tray is connected to an air outlet duct;

[0010] A plurality of scrapers are arranged in the dust removal box and are rotatably connected to the inner wall of the material tray.

[0011] The principles and effects of this basic solution are:

[0012] Compared with the prior art, the present invention not only uses airflow to adsorb impurities such as dust on the steel shots, but also utilizes the flow of airflow in the air guide ring cavity. Through the contact between the airflow and the blades, the rotating ring rotates and drives the material tray to rotate as a whole, which not only improves the adsorption effect of impurities, but also enables the steel shots adsorbed on the inner wall of the material tray to interact with the scraper, and the scraper is used to scrape the steel shots off, thereby preventing the steel shots from continuously clogging the through holes on the material tray.

[0013] Furthermore, a guide rod is provided in the dust removal box, the guide rod is rotatably connected to the material tray, and one end of the guide rod extends into the material tray and is provided with a connecting rod for installing the scraper. This method facilitates the installation of the scraper, so that the scraper is used to scrape off the steel shot adsorbed on the inner wall of the material tray.

[0014] Further, a material guide channel connected to the material outlet is provided inside the guide rod, a plurality of material guide holes connected to the material guide channel are provided on the side wall of the rod body of the guide rod located in the material tray, a sleeve sleeved on the peripheral end of the guide rod is provided in the material tray, a material guide groove which can be connected to the material guide hole is provided on the side wall of the sleeve, and an adjustment component for driving the guide rod to move vertically is provided on the dust removal box;

[0015] In the process of removing impurities from the steel shot, the sleeve blocks the material guide hole;

[0016] After the steel shot is decontaminated, the material guide groove is communicated with the material guide hole.

[0017] With this arrangement, the steel shots can stay in the material tray during the steel shot cleaning process, and after the steel shot cleaning is completed, the discharge of the steel shots can be conveniently controlled.

[0018] Furthermore, an inclined surface is provided at the bottom of the material tray, and the material guide trough is connected to the bottom of the inclined surface, so as to discharge the steel shot from the material tray and avoid the steel shot from accumulating in the dead corner of the material tray.

[0019] Furthermore, a feed port connected to the bottom of the feed hopper is provided on the top of the material tray, and a sealing plate capable of sealing the feed port is provided on the top of the guide rod. During the impurity removal process of the steel shot, the sealing plate seals the feed port. The sealing plate is used to seal the feed port to prevent air containing impurities from being discharged from the feed port during the impurity removal process of the steel shot, thereby affecting the working environment.

[0020] Further, the adjustment component comprises:

[0021] An air box is provided at the bottom of the dust removal box and is connected to the air flow duct, and the guide rod vertically penetrates the air box;

[0022] An adjusting block is arranged on the guide rod and located in the air box, wherein the bottom of the adjusting block is a flat surface and the top of the adjusting block is an arc-shaped surface.

[0023] Through this arrangement, when the airflow in the airflow duct passes through the air box, the airflow flows from the top and bottom of the adjusting block respectively and produces a flow velocity difference. The effect of the flow velocity difference causes a pressure difference between the top and bottom of the adjusting block, thereby generating an upward force on the adjusting block to drive the adjusting block and the guide rod to move vertically, so that the position of the guide rod can be controlled by controlling the flow velocity of the airflow channel.

[0024] Furthermore, the airflow duct includes an air inlet duct connected to the air box and an intermediate duct arranged between the air box and the air guide ring cavity. This arrangement enables the gas in the airflow duct to not only drive the material tray to rotate and clean the dust and impurities in the steel shot, but also to adjust the position of the guide rod.

[0025] Furthermore, a discharge pipe is provided at the bottom of the dust removal box, the guide rod is slidably connected in the discharge pipe, a retaining ring is provided on the rod body of the guide rod located in the discharge pipe, a baffle is provided at the bottom of the discharge pipe, and a return spring is provided between the baffle and the retaining ring. Through this arrangement, the return spring supports the guide rod, so that the overall gravity of the guide rod, the return spring and the vertical force acting on the adjustment block are balanced.

[0026] Furthermore, the baffle is provided with a sleeve slidably connected to the outer wall of the guide rod, and the height of the sleeve is higher than the vertical stroke of the guide rod. The provision of the sleeve can prevent a gap from forming between the bottom of the guide rod and the discharge pipe, which may cause the steel shot to get stuck between the guide rod and the discharge pipe.

[0027] Furthermore, the top of the dust removal box is provided with an annular raised surface, and the air guide ring cavity is located inside the raised surface, so as to maintain the airtightness of the air guide ring cavity and ensure the unity of the overall structure of the dust removal box.

[0035] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0037] A steel shot recovery device, for example Figures 1 to 3 As shown: it includes a dust removal box 1, a material tray 11 arranged inside the dust removal box 1, and a driving component for driving the material tray 11 to rotate.

[0038] The bottom of the dust removal box 1 is supported and fixed by three legs 2, the upper surface of the dust removal box 1 is provided with an annular raised surface 7, a feed hopper 3 is provided at the top center of the dust removal box 1, a discharge pipe 4 is provided at the bottom of the dust removal box 1, a baffle is provided at the bottom of the discharge pipe 4, and a discharge port is provided on the baffle.

[0039] The material tray 11 rotates in the dust removal box 1 , a feed port connected to the bottom of the feed hopper 3 is provided at the top of the material tray 11 , a plurality of through holes are provided on the circumference and the top of the material tray 11 , and an inclined surface is provided at the bottom of the material tray 11 .

[0040] The driving assembly includes an air guide ring cavity provided in the raised surface 7 of the dust removal box 1, a rotating ring 16 rotatably connected in the rotating ring 16 cavity, a plurality of blades 17 evenly provided on the rotating ring 16, and an air flow duct connected to the air guide ring cavity. The bottom of the rotating ring 16 passes through the dust removal box 1 and is connected to the top of the material tray 11. The end of the air flow duct is tangent to the air guide ring cavity. The side wall of the dust removal box 1 is provided with an air outlet duct 10 connected to the material tray 11.

[0041] like Figure 3 and 4 As shown, the bottom of the side of the air guide ring cavity away from the air flow duct is connected to the inside of the material tray 11 through a plurality of air guide holes 19 opened on the dust removal box 1, and a guide rod 12 is provided in the dust removal box 1, and the guide rod 12 extends into the material tray 11 and is rotatably connected to the material tray 11, and a sealing plate 13 that can seal the feed port is provided on the top of the guide rod 12, and a plurality of connecting rods 14 are provided on the side wall of the rod body of the guide rod 12 located in the material tray 11, and a scraper 15 rotatably connected to the inner wall of the material tray 11 is provided at the end of each connecting rod 14.

[0042] like Figure 3 and Figure 5 As shown, a material guide channel 22 connected to the material outlet is provided inside the guide rod 12, and a plurality of material guide holes 23 connected to the material guide channel 22 are provided on the side wall of the rod body of the guide rod 12 located in the material tray 11. A sleeve 20 is provided inside the material tray 11 and is sleeved on the peripheral end of the guide rod 12. A material guide groove 21 which can be connected to the material guide hole 23 is provided on the side wall of the sleeve 20. The material guide groove 21 is connected to the bottom of the inclined surface of the material tray 11, and an adjustment component for driving the guide rod 12 to move vertically is provided on the dust removal box 1.

[0043] like Figure 3As shown, the adjustment component includes an air box 5 arranged at the bottom of the dust removal box 1 and connected to the air flow duct, and an adjustment block 18 arranged on the guide rod 12 and located in the air box 5. The guide rod 12 vertically penetrates the air box 5. The bottom of the adjustment block 18 is a flat surface, and the top of the adjustment block 18 is an arc-shaped surface, so that when the airflow in the air flow duct passes through the air box 5, the airflow flows from the top and bottom of the adjustment block 18 respectively and generates a flow velocity difference. The effect of the flow velocity difference causes a pressure difference between the top and bottom of the adjustment block 18, thereby generating an upward force on the adjustment block 18 to drive the adjustment block 18 and the guide rod 12 to move vertically.

[0044] Due to the division of the air box 5, the air flow duct includes an intake duct 8 connected to the air box 5 and an intermediate duct 9 arranged between the air box 5 and the air guide ring cavity. The ends of the intake duct 8 and the intermediate duct 9 are respectively connected to the air box 5 through a rectangular connecting box 6.

[0045] like Figure 6 As shown, a baffle ring 24 is provided on the rod body of the guide rod 12 located in the discharge pipe 4, a baffle plate is provided at the bottom of the discharge pipe 4, a return spring 25 is provided between the baffle plate and the baffle ring 24, and a sleeve 26 is provided on the baffle plate that is slidably connected to the outer wall of the guide rod 12, and the height of the sleeve 26 is higher than the vertical stroke of the guide rod 12.

[0046] In this embodiment, the air flow duct is connected to the fan, and the fan has at least three gears. The wind speeds of the three gears drive the guide rod 12 to be located at different vertical heights respectively. The first gear is the lowest wind speed. At this time, the guide rod 12 is at the bottom, and the guide groove 21 is connected to the guide hole 23, which is used to discharge the steel shots after impurity removal; the second gear is the intermediate wind speed. At this time, the guide rod 12 is at the middle position, and the sleeve 20 blocks the guide hole 23, so that the guide groove 21 is not connected to the guide hole 23, and a gap for steel shots to pass through is formed between the sealing plate 13 and the guide hole 23, which is used to pass steel shots that need to be removed from impurities into the material tray 11; the third gear is the highest wind speed. At this time, the guide rod 12 is at the top, the sleeve 20 blocks the guide hole 23, so that the guide groove 21 is not connected to the guide hole 23, and the sealing plate 13 blocks the feed port, which is used to remove impurities from the steel shots.

[0047] When removing impurities from the steel shots, first adjust the fan to the second gear and feed the steel shots to be removed into the material tray 11; then adjust the fan to the third gear to remove impurities from the steel shots, and then adjust the fan to the first gear to discharge the steel shots after the impurities are removed.

[0048] In this embodiment, not only the flow velocity of the air flow channel is controlled to control the position of the guide rod 12, but also the flow of air in the air guide ring cavity is utilized to make the rotating ring 16 rotate through the contact between the air flow and the blades 17, and drive the material tray 11 to rotate as a whole, which can not only improve the adsorption effect of impurities, but also make the steel shots adsorbed on the inner wall of the material tray 11 interact with the scraper 15, and use the scraper 15 to scrape the steel shots off, so as to avoid the steel shots continuously clogging the through holes on the material tray 11, and solve the problem that in the traditional steel shot recycling, when a negative pressure fan is used to separate impurities from the steel shots, the steel shots themselves are easily attached to the surface of the filter screen by the suction force, which affects the normal conduction of air and impurities and leads to the frequent cleaning of the filter screen.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
