Description

Technical Field

[0001] This utility model relates to a drying device, specifically a drying device for quartz sand production, and belongs to the field of quartz sand production technology. Background Technology

[0002] Quartz sand is quartz particles produced by processing quartz stone through crushing and screening. Quartz stone is a non-metallic mineral, and its main mineral component is silicon dioxide. When mining quartz sand raw materials, if the moisture content is high, or if moisture is introduced during the crushing and screening process, a dryer is needed to remove the moisture from the raw materials.

[0003] However, when drying quartz sand in a rotary dryer, if the local temperature of the furnace is too high or the material does not tumble sufficiently in the furnace, the material may overheat and stick together to form larger particles. These large particles, when mixed with the dried material, can easily affect the subsequent processing of the quartz sand. Furthermore, the material is too hot when it comes out of the furnace, resulting in low natural cooling efficiency, which is not conducive to improving the processing effect of the quartz sand. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for quartz sand production in order to solve the above-mentioned problems. Cold water is injected into the cooling pipe through the water pipe. When the material frame drives the clamping plate to slide back and forth, the clamping plate moves within the fixed frame and the limiting plate. Thus, while the freshly dried quartz sand is rapidly cooled through the cooling pipe, larger particles of quartz sand can be screened through the screen installed in the material frame, thereby improving the drying effect of quartz sand.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a drying device for quartz sand production, comprising a machine body, a furnace body rotatably mounted inside the machine body, a fixed frame fixedly connected to the machine body, a hopper mounted on the fixed frame, a material frame connected to the bottom end of the hopper, a cooling mechanism slidably mounted on the fixed frame, the cooling mechanism comprising a limiting plate and a clamping plate, two sets of limiting plates symmetrically fixedly connected to the fixed frame, a clamping plate slidably connected to the fixed frame and the limiting plates, the clamping plate being fixedly connected to the material frame, a screen fixedly mounted inside the material frame, a cooling pipe fixedly mounted to the bottom end of the material frame, both ends of the cooling pipe being connected to water pipes, and a driving mechanism installed between the fixed frame and the material frame.

[0006] Preferably, the screen is located at one end of the material frame away from the machine body, and the part of the material frame near the screen is set with an inclined structure.

[0007] Preferably, the cooling mechanism further includes a rotating wheel, and a plurality of rotating wheels are equidistantly rotatably connected within the card plate, and the rotating wheels are rolledly connected to the fixed frame.

[0008] Preferably, the two limiting plates are symmetrically arranged about the card plate, and the limiting plates are arranged in an L-shape.

[0009] Preferably, the driving mechanism includes a fixed plate and a motor. The fixed plate is fixedly connected to the fixed frame near the material frame. The motor is fixedly mounted on the fixed plate. The output shaft of the motor is fixedly connected to a turntable. A limit rod is fixedly mounted on the turntable. A rotating rod is rotatably connected to the limit rod. An installation block is fixedly connected to the material frame. The rotating rod and the installation block are rotatably connected.

[0010] Preferably, the turntable is rotatably connected to the fixed plate, and the rotating rod is inclined.

[0011] Preferably, a number of sets of lifting plates are fixedly connected in a ring at equal intervals inside the furnace body, and the lifting plates are inclined.

[0012] Preferably, the furnace body is rotatably connected to the side of the hopper closest to the machine body, and the hopper is in communication with the interior of the furnace body.

[0013] Preferably, the furnace body is provided with a conical structure at one end near the hopper, the top of the hopper is provided with a sloping structure, and the middle part of the hopper is provided with an arc-shaped structure.

[0014] The beneficial effects of this utility model are as follows: Cold water can be transported to the cooling pipe fixed at the bottom of the material basket through the water pipe. Since the cooling pipe is set with an arc structure, the cooling effect at the bottom of the material basket can be improved. When the dried quartz sand is discharged into the material basket through the hopper, the material basket can be driven to slide back and forth by the drive mechanism. Two clamping plates are fixed on both sides of the material basket. The limiting plates installed on both sides of the fixing frame limit the clamping plates, so that when the material basket slides, it drives the clamping plates to slide within the fixing frame and the limiting plates. The back and forth movement of the material basket can enable the screen installed inside to screen larger particles of quartz sand, thereby improving the drying effect of quartz sand and also rapidly cooling the quartz sand.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-7As shown, a drying device for quartz sand production includes a machine body 1, a furnace body 2 rotatably installed inside the machine body 1, a fixed frame 4 fixedly connected to the machine body 1, a hopper 3 installed on the fixed frame 4, a material frame 5 connected to the bottom of the hopper 3, and a cooling mechanism 6 slidably installed on the fixed frame 4. The cooling mechanism 6 includes a limiting plate 602 and a clamping plate 603. Two sets of limiting plates 602 are symmetrically fixedly connected to the fixed frame 4. The limiting plates 602 are arranged in an L-shape. The clamping plate 603 is slidably connected to the fixed frame 4 and the limiting plates 602. The material frame 5 drives the clamping plate 603 to slide within the fixed frame 4 and the limiting plates 602, allowing the material frame 5 to slide back and forth. The back-and-forth movement of the material frame 5 allows the internal screen 605 to screen larger particles of quartz sand, thereby improving the drying effect of the quartz sand and also rapidly cooling the quartz sand. A plurality of rotating wheels 604 are equidistantly rotatably connected within the pallet 603. The rotating wheels 604 are rolledly connected to the fixed frame 4. The arrangement of the rotating wheels 604 can improve the sliding effect of the pallet 603. The pallet 603 is fixedly connected to the material frame 5. A screen 605 is fixedly installed inside the material frame 5. The screen 605 is located at the end of the material frame 5 away from the machine body 1, and the part of the material frame 5 near the screen 605 is set with an inclined structure. A cooling pipe 606 is fixedly installed at the bottom of the material frame 5. Both ends of the cooling pipe 606 are connected to water pipes 601. Cold water can be transported into the cooling pipe 606 through the water pipes 601. The cooling pipe 606 is set with an arc-shaped structure. Through a circulation pump, the cold water can be circulated in the cooling pipe 606, thereby improving the cooling effect at the bottom of the material frame 5. A drive mechanism 7 is installed between the fixed frame 4 and the material frame 5.

[0025] As a technical optimization of this utility model, the driving mechanism 7 includes a fixed plate 701 and a motor 706. The fixed plate 701 is fixedly connected to the fixed frame 4 near the material frame 5. The motor 706 is fixedly installed on the fixed plate 701. The output shaft of the motor 706 is fixedly connected to a turntable 702. The turntable 702 is rotatably connected to the fixed plate 701. A limit rod 703 is fixedly installed on the turntable 702. A rotating rod 704 is rotatably connected to the limit rod 703. An installation block 705 is fixedly connected to the material frame 5. The rotating rod 704 is rotatably connected to the installation block 705. When the motor 706 is turned on, the motor 706 drives the turntable 702 to rotate on the top of the fixed plate 701. The limit rod 703 drives the rotating rod 704 installed on the side wall to rotate, so that the rotating rod 704 drives the material frame 5 fixed on the installation block 705 to move.

[0026] As a technical optimization of this utility model, several sets of lifting plates 8 are fixedly connected in a ring at equal intervals inside the furnace body 2. The lifting plates 8 are inclined. During the rotation of the furnace body 2, the lifting plates 8 can rotate. When the lifting plates 8 come into contact with the quartz sand, they can lift the material at the bottom of the furnace body 2 to a certain height and then drop it to form a material curtain. This allows the hot air inside the furnace body 2 to fully penetrate the gaps between the materials, thereby improving the drying effect of the materials.

[0027] As a technical optimization of this utility model, the furnace body 2 and the hopper 3 are rotatably connected on the side near the machine body 1, and the hopper 3 is connected to the interior of the furnace body 2. The quartz sand to be dried can be put into the furnace body 2 through the hopper 3. Since the part of the furnace body 2 that contacts the hopper 3 is set with a conical structure, the quartz sand can enter the furnace body 2. The top of the hopper 3 is set with a sloping structure, and the middle part of the hopper 3 is set with an arc structure. After the quartz sand is dried, the material can be discharged into the material frame 5 through the hopper 3.

[0028] In use, this invention first allows the quartz sand to be dried to be fed into the furnace body 2 via the hopper 3. Since the contact area between the furnace body 2 and the hopper 3 is conical, when the quartz sand enters the furnace body 2, the rotation of the furnace body 2 causes several sets of lifting plates 8 to rotate. The lifting plates 8 contact the quartz sand, lifting the material from the bottom of the furnace body 2 to a certain height before dropping it, forming a material curtain. This allows the hot air inside the furnace body 2 to fully penetrate the gaps between the materials, resulting in better drying. After the quartz sand is dried, it is discharged into the material frame 5 via the hopper 3. Cold water is then transported to the cooling pipe 606 fixed at the bottom of the material frame 5 via a water pipe 601 installed on the circulating pump. The cooling pipe 606 is arc-shaped, and the circulating pump allows the cold water to circulate within it, thereby improving the cooling effect at the bottom of the material frame 5. Effect: When processing quartz sand, the motor 706 switch installed on the fixed plate 701 is turned on. The motor 706 drives the turntable 702 to rotate on the top of the fixed plate 701. The turntable 702 is fixed with a limit rod 703. The limit rod 703 drives the rotating rod 704 installed on the side wall to rotate, so that the rotating rod 704 drives the material frame 5 fixed on the mounting block 705 to move. Since the side wall of the material frame 5 is fixed with a clamping plate 603, the clamping plate 603 is limited by the fixed frame 4 and the limit plate 602. When the material frame 5 drives the clamping plate 603 to slide within the fixed frame 4 and the limit plate 602, the material frame 5 can slide back and forth. A screen 605 is installed at the end of the material frame 5 away from the mounting block 705. The back and forth movement of the material frame 5 can make the internal screen 605 screen larger particles of quartz sand, thereby improving the drying effect of quartz sand and also rapidly cooling the quartz sand.
