Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a shot blasting machine shot recycling and processing device. Background Technology

[0002] Shot blasting machines are commonly used metal surface treatment equipment in the foundry industry. By using shot blasting machines to treat metal surfaces, rust, oxide scale, welding slag, and cast scale can be removed, preparing the metal surface for subsequent coating and plating. On the other hand, shot blasting can also improve the tensile strength and fatigue strength of metal materials, change the stress state of the material surface, enhance its wear resistance and corrosion resistance, and extend the product life.

[0003] After shot blasting, some of the shot will break due to impact and friction, failing to meet the standards for reuse. The discarded metal waste is also mixed in with the shot, making subsequent recycling difficult.

[0004] In the prior art, such as the defective cast steel shot recycling equipment disclosed in patent CN220590670U, the vibration of the screening chute allows the produced cast steel shot to be graded and screened through the fine screen and standard screen in the screening chute. The cast steel shot with a smaller diameter will be discharged through the second chute, thereby screening out the unqualified cast steel shot and recycling it.

[0005] Although the above-mentioned device can realize the recycling and utilization of pellets, a large amount of dust is generated during the screening process due to vibration. Moreover, the screening mechanism is in an exposed state, and this dust will spread to the outside world, causing environmental pollution and endangering the health of workers. Therefore, it needs to be improved. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model discloses a shot recycling and processing device for a shot blasting machine, including a frame, a vibrating screen, a vibrating motor, a buffer spring, a spraying mechanism, and a discharge hopper. The vibrating screen is inclinedly mounted on the frame and is movably connected to the frame at its four corners via buffer springs. The vibrating motor is mounted on both sides of the vibrating screen. The spraying mechanism is mounted above the vibrating screen and near the feeding end via a bracket. The discharge hopper is located at the bottom of the frame, corresponding to the spraying mechanism. The spraying mechanism includes multiple spray pipes arranged side by side on the bracket, and the spray pipes span the vibrating screen. Each spray pipe has multiple spray nozzles spaced apart at its bottom.

[0007] Furthermore, the vibrating screen has several screen holes on the side near the feed end and a planar structure on the side near the discharge end.

[0008] Furthermore, a drying mechanism is provided on the side of the vibrating screen near the discharge end. The drying mechanism includes a machine cover, a fan, and electric heating tubes. The fan is arranged horizontally inside the machine cover, and the electric heating tubes are arranged at intervals inside the machine cover and located at the bottom of the fan.

[0009] Furthermore, an air inlet is provided on the top of the hood.

[0010] Furthermore, a feed hopper is also provided on the frame above the feeding end of the vibrating screen.

[0011] Furthermore, the vibrating screen is provided with a feeding sloping plate at its end.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a spraying mechanism to spray the pellets during the screening process. On the one hand, it can prevent dust from spreading during the screening process, thereby improving the production environment. On the other hand, it can also clean the pellets, making them easier to use later. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0023] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0024] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1 As shown, the shot blasting machine shot recycling device in this embodiment includes a frame 1, a vibrating screen 2, a vibrating motor 3, a buffer spring 4, a spraying mechanism 5, a drying mechanism 6, a discharge hopper 7, a feeding hopper 8, and a discharge inclined plate 9.

[0026] The vibrating screen 2 is inclinedly mounted on the frame 1 and is movably connected to the frame 1 at all four corners by buffer springs 4. The vibrating motor 3 is mounted on both sides of the vibrating screen 2, and the vibrating screen 2 is driven to vibrate by the vibrating motor 3. The buffer springs 4 can block the vibration from being transmitted to the frame 1.

[0027] The spraying mechanism 5 is mounted above the vibrating screen 2 and close to the feeding end via the bracket 10, and the discharge hopper 7 is mounted at the bottom of the frame 1 at a position corresponding to the spraying mechanism 5; the drying mechanism 6 is mounted above the vibrating screen 2 on the side close to the discharge end.

[0028] The feed hopper 8 is set on the frame 1 and above the feeding end of the vibrating screen 2, and is used to transport the pellets to the vibrating screen 2; the discharge sloping plate 9 is set at the end of the vibrating screen 2, and is used to guide the screened pellets out of the device.

[0029] like Figure 2As shown, the spraying mechanism 5 includes multiple spray pipes 51 arranged side by side on the support 10, and the spray pipes 51 are arranged across the vibrating screen 2. Each spray pipe 51 has multiple spray nozzles 52 spaced apart at its bottom. The spray pipes 51 are connected to an external water source and are evenly sprayed onto the pellets on the vibrating screen 2 through the spray nozzles 52.

[0030] like Figure 3 As shown, the vibrating screen 2 has several screen holes 21 on the side near the feed end and a planar structure on the side near the discharge end.

[0031] like Figure 4 As shown, the drying mechanism 6 includes a machine cover 61, a fan 62 and an electric heating tube 63. The fan 62 is arranged horizontally inside the machine cover 61, and the electric heating tube 63 is arranged at intervals inside the machine cover 61 and located at the bottom of the fan 62. An air inlet 64 is provided at the top of the machine cover 61.

[0032] In operation, the used pellets are conveyed to the feed end of the vibrating screen 2 via the feed hopper 8. The vibrating motor 3 drives the vibrating screen 2 to vibrate. Due to the inclined setting of the vibrating screen 2, the pellets will gradually move towards the discharge end under the action of vibration. The size of the screen hole 21 is smaller than the size of normal pellets but larger than the size of waste and residue particles. The waste and residue fall through the screen hole 21 into the discharge hopper 7 below. A receiving box can be placed at the bottom of the discharge hopper 7 to receive waste and residue.

[0033] External water is evenly sprayed onto the pellets through spray nozzle 52. This not only prevents dust from spreading during the screening process, thus improving the production environment, but also cleans the pellets for subsequent use.

[0034] When the normal-sized pellets move to the bottom of the drying mechanism 6, the fan 62 and the electric heating tube 63 start to work. The fan 62 blows the heat generated by the electric heating tube 63 onto the pellets to perform preliminary drying of the cleaned pellets in order to reduce moisture. The dried pellets are finally discharged from the discharge inclined plate 9 at the end of the vibrating screen 2.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
