Description

Technical Field

[0001] This utility model relates to the field of granulation technology, specifically to an alloy steel shot granulation device. Background Technology

[0002] Alloy steel shot has wide applications in many industrial fields. For example, in the surface strengthening treatment of mechanical parts, shot blasting with alloy steel shot can significantly improve the surface hardness, fatigue strength, and corrosion resistance of the parts. In the cleaning process of metal products, alloy steel shot can effectively remove impurities such as oxide scale and rust from the workpiece surface, enabling the workpiece surface to achieve high cleanliness and roughness requirements, providing a good foundation for subsequent processing and coating processes.

[0003] The reference patent, entitled "An Alloy Steel Shot Granulation Device" (Publication No. CN219881305U, Publication Date 2023-10-24), utilizes functional components to facilitate the screening of alloy steel shot as it is discharged through the discharge pipe. This allows for the separation of larger alloy steel shot particles, eliminating the need for manual sorting and screening. The device boasts excellent functionality and allows for quick replacement of mounting plates with different screen apertures, enhancing its applicability. Furthermore, the designed limiting components provide auxiliary restraint when the lower tank is rotated to connect with the upper tank, preventing the lower tank from shifting when the worker secures the upper and lower tanks using the locking mechanism.

[0004] Based on the above patent, after granulation, the device controls the particle size of the steel shot through screening. However, the screening mechanism of existing alloy steel shot granulation devices is mostly difficult to directly adjust the screening particle size as needed. In practical applications, relevant personnel need to replace the screening tools, which is time-consuming and labor-intensive. Therefore, this utility model provides an alloy steel shot granulation device. Utility Model Content

[0015] Beneficial effects

[0016] This invention provides an alloy steel shot granulation device. Compared with the prior art, it has the following advantages:

[0017] 1. This alloy steel shot granulation device can precisely adjust the relative position between the lower and upper grids by simply rotating the rotating rod, using the combination of gear and screw transmission, according to different production needs.

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: an alloy steel shot granulation device, specifically including the following embodiments:

[0027] Example 1: An alloy steel shot granulation device includes a granulator 1 and a screening mechanism 2 at the upper end of the granulator 1. The screening mechanism 2 includes: a separation component 21, disposed on one side of the granulator 1, comprising a housing 211 slidably mounted on one side of the granulator, an upper grid 212 and a guide rod 215 fixed to the inner wall of the housing 211, a guide plate 214 slidably mounted laterally on the guide rod 215, a lower grid 213 fixed to the upper end of the guide plate 214, and the gaps between the lower grid 213 and the upper grid 21 are staggered; an inclined groove is provided at the lower end of the guide plate 214, and a horizontal block 216 is slidably mounted inside the inclined groove; and an adjustment component 22, disposed at the front end of the housing 211, for pushing the horizontal block 216 along the guide plate 214. The inclined trough on the screen moves; the screening component 23 is set on one side of the granulator 1 and is used to drive the box 211 to move up and down; by rotating the rotating rod 222, the rotating rod 222 drives the small gear 223 to rotate. Since the small gear 223 meshes with the large gear 224, the large gear 224 drives the threaded sleeve 225 to rotate. When the threaded sleeve 225 rotates, the screw 226 connected to it by the thread will move along the thread direction. The screw 226 drives the horizontal block 216 to slide in the inclined trough at the lower end of the guide plate 214. The sliding of the horizontal block 216 will push the guide plate 214 to slide laterally on the guide rod 215, thereby changing the relative position between the lower grid 213 and the upper grid 212, and realizing the adjustment of the screening gap size.

[0028] Example 2: The main difference between this example and the first technical solution is that: an alloy steel shot granulation device, the adjusting component 22 includes a drive box 221 fixedly installed on the outer wall of the front end of the housing 211, a rotating rod 222 and a threaded sleeve 225 rotatably installed on the drive box 221, a small gear 223 fixed on the rotating rod 222, a large gear 224 meshing with the small gear 223 fixed on the threaded sleeve 225, and a screw 226 threadedly connected to one end of the threaded sleeve 225, the end of the screw 226 being fixed to the cross block 216, the screening component 23 includes a mounting plate 231 fixed to one side of the granulator 1, and a motor 232 fixedly installed on the upper part of the mounting plate 231, a transmission shaft 233 connected to one end of the motor 232, and a movable push rod 23 fixed to the end of the transmission shaft 233. 4. The lower end of the movable push rod 234 is rotatably connected to the connecting rod 235, and the connecting rod 235 is connected to the inner wall of the box 211. The outer walls on both sides of the box 211 are fixed with support rod sleeves 3, and the lower end of the support rod sleeves 3 is slidably inserted with support rods 4 fixed to the bottom plate of the granulator 1. By starting the motor 232 of the screening assembly 23, the motor 232 drives the transmission shaft 233 to rotate, and the transmission shaft 233 drives the movable push rod 234 at the end to make a circular motion. The lower end of the movable push rod 234 drives the box 211 to move up and down through the connecting rod 235. With the cooperation of the support rod sleeves 3 and the support rods 4, the box 211 makes a stable up and down reciprocating motion. During the up and down movement of the box 211, alloy steel shot enters the box 211 from the granulator 1 and is screened by the staggered upper grid 212 and lower grid 213.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] During operation, after the alloy steel shot is granulated in the granulator 1, it enters the screening mechanism 2 for particle size screening. Personnel rotate the rotating rod 222 according to the required alloy steel shot particle size specifications. The rotating rod 222 drives the small gear 223 to rotate. Since the small gear 223 meshes with the large gear 224, the large gear 224 drives the threaded sleeve 225 to rotate. When the threaded sleeve 225 rotates, the screw 226 connected to it moves along the thread direction. The screw 226 drives the transverse block 216 to slide in the inclined groove at the lower end of the guide plate 214. The sliding of the transverse block 216 pushes the guide plate 214 to slide laterally on the guide rod 215, thereby changing the relative position between the lower grid 213 and the upper grid 212, achieving... The size of the screening gap is adjusted; then the motor 232 of the screening assembly 23 is started. The motor 232 drives the transmission shaft 233 to rotate. The transmission shaft 233 drives the movable push rod 234 at the end to make a circular motion. The lower end of the movable push rod 234 drives the box 211 to move up and down through the connecting rod 235. With the cooperation of the support sleeve 3 and the support rod 4, the box 211 moves up and down stably. During the up and down movement of the box 211, the alloy steel shot enters the box 211 from the granulator 1 and is screened by the staggered upper grid 212 and lower grid 213. During the dynamic process of moving up and down, the alloy steel shot of different sizes passes through the grids with corresponding gaps, realizing the screening and classification of the alloy steel shot by size.
