DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 and Figure 2 , 3 The utility model provides a continuous heat treatment and recovery device for regenerated sand, including a furnace body 1, a flame spraying device 2, a loading material cabin assembly 3, a discharging gate assembly 4, and a material spreading mechanism 6 are installed inside the furnace body 1, and a recovery mechanism 5 is fixedly installed at the bottom of the furnace body 1, the loading material cabin assembly 3 is used to store the regenerated sand to be processed, the discharging gate assembly 4 is used to intercept the regenerated sand inside the furnace body 1, and the material spreading mechanism 6 is used to spread the regenerated sand on the top of the discharging gate assembly 4 evenly;

[0025] The recovery mechanism 5 includes four standing feet 51, and the inner walls of the four standing feet 51 are fixedly installed with a primary screening mechanism 52, a secondary screening mechanism 53, and a ramp 54 from top to bottom. The primary screening mechanism 52, the secondary screening mechanism 53, and one side of the unloading gate assembly 4 are connected to three collecting containers through three discharge hoppers 55 respectively.

[0026] Reference Figure 3 The primary screening mechanism 52 and the secondary screening mechanism 53 have the same structure. The primary screening mechanism 52 includes a frame plate 521. The inner wall of the frame plate 521 is fixedly connected with a screen plate 522. The side wall of the frame plate 521 is fixedly installed with a vibration motor 523. The bottom of the frame plate 521 is connected to four feet 51 through four support blocks 524. The screen plate 522 has an inclination of ten to fifteen degrees. The regenerated sand that falls to the top of the screen plate 522 is subjected to primary screening under the vibration effect of the vibration motor 523. The screened regenerated sand passes through the inclination of the screen plate 522 and slides into the discharging hopper 55 for discharging. Since the primary screening mechanism 52 and the secondary screening mechanism 53 have the same structure, the secondary screening mechanism 53 performs secondary screening in the same way.

[0027] Reference Figure 3 A shock-absorbing rubber pad is provided at the connection between the support block 524 and the frame plate 521 to prevent the vibration force from being transmitted to the standing foot 51.

[0028] Reference Figure 4 The unloading gate assembly 4 includes an auxiliary gate 41, a main gate 42, an auxiliary swivel 43, a main swivel 44, a rotary control mechanism 1 45, and a rotary control mechanism 2 46. The outer sides of the auxiliary gate 41 and the main gate 42 are movably connected in the furnace body 1 through the auxiliary swivel 43 and the main swivel 44. The positive ends of the auxiliary swivel 43 and the main swivel 44 penetrate to the front of the furnace body 1 and connect with the rotary control mechanism 1 45 and the rotary control mechanism 2 46. The rotary control mechanism 1 45 and the rotary control mechanism 2 46 are fixedly installed on the front of the furnace body 1. When the auxiliary gate 41 and the main gate 42 are in a horizontal state, their inner sides are closed to intercept the regenerated sand. The main swivel 44 is driven to rotate by the rotary control mechanism 2 46 to make the main gate 42 turn downward by 20 degrees. The auxiliary swivel 43 is driven to rotate by the rotary control mechanism 1 45 to make the auxiliary gate 41 turn downward by 10 degrees. At this time, the regenerated sand intercepted on the top of the auxiliary gate 41 and the main gate 42 slides downward under the influence of the inclination, thereby achieving an automatic unloading effect.

[0029] Reference Figure 4The structures of the rotary control mechanism 1 45 and the rotary control mechanism 2 46 are the same. The rotary control mechanism 1 45 includes two connecting plates 451.

The output shaft of the motor 1 453 penetrates the connecting plate 451 and is connected to the worm 452. The worm 452 is driven to rotate by the output power of the motor 1 453. The rotation effect of the secondary rotating shaft 43 is controlled by the meshing relationship between the worm 452 and the worm wheel 454. The rotary control mechanism 2 46 drives the main rotating shaft 44 to rotate in the same way.

When the furnace body 1 is loaded, the threaded rod 1 33 is driven to rotate by the output power of the motor 2 35, and the shifting plate 34 is moved horizontally under the influence of the threaded structure, and the material cutting plate 32 is driven by the shifting plate 34 so that it does not intercept the regenerated sand, and the material can be automatically unloaded under the influence of gravity.

[0031] Reference Figure 6 The paving mechanism 6 includes a nail plate 61, a positioning shaft 62, a second threaded rod 63, and a third motor 64.

Under the influence of the threaded structure, the nail plate 61 can be moved, and the regenerated sand accumulated on the top of the unloading gate assembly 4 can be pushed by the nail plate 61 to achieve the effect of evenly paving the regenerated sand.

[0032] The working principle of the utility model is as follows: the regenerated sand to be processed is stored through the loading material bin assembly 3 and automatically loaded into the furnace body 1, the regenerated sand entering the furnace body 1 is received through the unloading gate assembly 4, the regenerated sand on the top of the unloading gate assembly 4 can be evenly spread through the paving mechanism 6, and then the flame spraying device 2 is operated to perform flame spraying heat treatment, and when the unloading gate assembly 4 is completed, the unloading is completed through the operation of the unloading gate assembly 4, and the flame spraying device 2 does not need to stop running during the process. After the automatic unloading is completed, the material is discharged again through the loading material bin assembly 3 to perform heat treatment of the next batch of hot regenerated sand, and the equipment does not need to stop running during this process, thereby completing the continuous heat treatment operation;

[0033] The regenerated sand discharged through the unloading gate assembly 4 enters the recovery mechanism 5, and is screened through the primary screening mechanism 52 to select the first-grade coarse and fine regenerated sand. The regenerated sand passing through the primary screening mechanism 52 is screened through the secondary screening mechanism 53 to select the second-grade coarse and fine regenerated sand. The regenerated sand passing through the secondary screening mechanism 53 is the third-grade coarse and fine regenerated sand, which falls to the top of the ramp plate 54. The regenerated sands of different grades of coarse and fine on the primary screening mechanism 52, the secondary screening mechanism 53 and the ramp plate 54 are discharged through three discharge hoppers 55 respectively, and are collected separately through three collecting volumes, thereby completing the screening and recovery effect.
