DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention that does not depart from the spirit and scope of the technical solution of the present invention should be included in the scope of protection of the present invention.

[0021] like Figure 1 As shown, the utility model proposes an automatic feeding and discharging device for quartz sand, which is composed of a feeding mechanism 1, a feeding mechanism 2, a magnetic separation and filtration mechanism 3 and a discharge mechanism 4. The feeding mechanism 1 is arranged on the left side of the feeding mechanism 2, and its feeding port is arranged at the quartz sand storage place, and the discharge port is located above the feeding port of the feeding mechanism 2; the feeding mechanism 2 is arranged on the right side of the feeding mechanism 1, the magnetic separation and filtration mechanism 3 is arranged below the feeding mechanism 2, and the discharge mechanism 4 is arranged below the magnetic separation and filtration mechanism 3. The four are connected in sequence in the form of the discharge port connected to the feeding port. When in use, the quartz sand is transported to the feeding mechanism 2 through the feeding mechanism 1, and then transported to the discharge mechanism 4 after the magnetic separation and filtration mechanism 3 screens out magnetic impurities. The discharge operation is completed by the discharge mechanism 4, realizing a continuous production and processing process.

[0022] Specifically, the feeding mechanism 2 includes a base 14 and a conveyor chain 12. A conveying motor 13 and a frequency converter are fixedly mounted on the base 14. The frequency converter is connected to the conveying motor 13 and is used to control the speed of the conveying motor 13. The conveyor chain 12 is mounted on the base 14 and is inclined at an angle of 30°. It is driven by the conveying motor 13. A closed conveying protective cover 11 is provided above the conveyor chain 12 to realize a closed feeding process to ensure that quartz dust does not leak out.

[0023] The feeding mechanism 2 includes a storage bin 21 and a conical hopper 22. The storage bin 21 is square in shape and is located at the discharge port of the conveyor chain 12. The conical hopper 22 is located below the storage bin 21 and is fixedly connected to the storage bin 21. To ensure airtightness during the entire process, the conical hopper 22 and the storage bin 21 are integrally formed or connected by welding or other methods. An upper limit sensor 23 is provided near the top of the storage bin 21 to sense whether the material in the storage bin 21 is full, so as to adjust the conveying speed of the conveyor chain 12 accordingly to avoid quartz sand overflow. A lower limit sensor 24 is installed near the bottom end face of the storage bin 21. When the quartz sand in the storage bin 21 is lower than the lower limit sensor 24, the information will be transmitted to the sound and light alarm, which will sound to remind the staff to add material to avoid the machine from idling continuously after the quartz sand is used up.

[0024] The magnetic separation and filtration mechanism 3 includes a fixed frame 31, the upper end of which is connected to the discharge port of the conical hopper 22, and the lower end is connected to the discharge mechanism 4, and both connections are sealed. Three layers of filter layers 32 are arranged in sequence from top to bottom in the fixed frame 31, and the three layers of filter layers 32 are arranged at equal intervals; the first layer of filter layer 32 is composed of three magnetic rods, the second layer of filter layer 32 is composed of four magnetic rods, and the third layer of filter layer 32 is composed of three magnetic rods; the magnetic rods in each layer of filter layer 32 are arranged in a horizontal direction, and the distance between each two magnetic rods is set to 10mm. When in use, when the quartz sand material is transported from the conical hopper 22 to the magnetic separation and filtration mechanism 3, it passes through the three layers of filter layers 32 in sequence, so that magnetic impurities such as iron foam in the quartz sand can be separated by multiple magnetic rods, thereby achieving the purpose of removing impurities and purifying.

[0025] The discharge mechanism 4 includes a discharge elbow 41 and a discharge pipe 42. The discharge elbow 41 is located below the magnetic separation and filtration mechanism 3. The upper end of the discharge elbow 41 is sealed with the discharge port of the fixed frame 31, and the lower end is sealed with the discharge pipe 42. One end of the discharge pipe 42 is sealed with the discharge port of the discharge elbow 41. It is arranged in a horizontal direction and is slightly inclined. The inclination angle of the discharge pipe 42 is set between 5 and 15 degrees according to the use environment and the discharge speed requirements during discharge. Two vibration motors 43 are provided at the bottom of the discharge pipe 42. A vibration trough platform is installed on the two vibration motors 43. The discharge pipe 42 is fixedly mounted on the vibration trough platform. A vibration sensor is also fixedly mounted on the vibration trough platform for automatically controlling the vibration frequency of the vibration motor 43 through the control system to control the speed of automatic discharge. Preferably, when the control system is not used, the vibration frequency of the vibration motor 43 and the inclination angle of the discharge pipe 42 can also be manually adjusted to adjust the discharge speed of the discharge pipe 42.

[0026] Working principle:

[0027] During use, the quartz sand is transported to the storage bin 21 by the conveyor chain 12, and then transported to the magnetic separation and filtration mechanism 3 through the conical hopper 22. The heavy magnetic impurities in the quartz sand are screened out through the multi-layer filter layer 32 in the magnetic separation and filtration mechanism 3. The purified quartz sand is then transported to the discharge pipe 42 through the discharge elbow 41, and the discharge is carried out in combination with the vibration motor 43, thereby realizing a continuous and automatic loading and unloading process.

[0028] The present invention combines a feeding mechanism 1 with a discharge mechanism 4, which cooperates with the feeding mechanism 2 to achieve a continuous re-feeding and discharge process of quartz sand, thereby improving processing efficiency. Furthermore, by adding a magnetic separation and filtration mechanism 3 between the feeding mechanism 2 and the discharge mechanism 4, magnetic impurities such as iron foam can be separated from the quartz sand, thereby achieving the purpose of purifying the quartz sand.
