Description

Technical Field

[0001] This utility model relates to the field of quartz sand processing technology, specifically to a quartz sand raw material pre-drying device. Background Technology

[0002] Quartz sand, as a basic raw material of modern industry, occupies an indispensable position in many fields such as building materials, glass, casting, electronics and photovoltaics. However, freshly mined or processed quartz sand raw materials usually contain a lot of moisture, which will bring many adverse effects to the subsequent production process.

[0003] Chinese utility model patent application number 202223085064.5 provides a drying device for quartz sand processing. On the one hand, it can realize the high-frequency up-and-down vibration of the receiving plate through the cooperation of a vibrating motor and a spring rod, thereby ensuring that the quartz sand raw material falling onto the receiving plate can be dried during the high-frequency up-and-down vibration. The advantage of this drying method is that it can ensure that hot air can fully penetrate the quartz sand particles, thereby effectively shortening the drying time of quartz sand and improving the drying efficiency of the device. On the other hand, the high-frequency vibration of the receiving plate can also realize the automatic falling of the dried quartz sand, thereby realizing the automatic discharge of the device and improving the discharge efficiency of quartz sand after drying.

[0004] However, during the use of the above equipment, it was found that the receiving plate was tilted. When the vibrating motor controlled the receiving plate to vibrate, if the quartz sand particles were small and had a relatively regular shape, their fluidity would be better. Under the action of vibration and gravity, they would fall more quickly, resulting in insufficient drying time and affecting the drying effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pre-drying device for quartz sand raw materials, which solves the problem mentioned in the background technology that if the quartz sand particles are small and have a relatively regular shape, their fluidity will be better, and they will fall more quickly under the action of vibration and gravity, resulting in insufficient drying time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-drying device for quartz sand raw materials, comprising a support frame, a conveyor frame fixedly mounted on the top of the support frame, a first motor mounted on the rear end of the conveyor frame, a conveying component mounted inside the conveyor frame, the conveying component including a rotating shaft, the rotating shaft being rotatably mounted in the conveyor frame and connected to the output end of the first motor, a spiral blade fixedly mounted on the rotating shaft, actuating rods being equidistantly arranged on the surface of the spiral blades, the actuating rods being spirally arranged along the surface of the spiral blades, a feed box mounted on the rear end of the conveyor frame, an output pipe connected to the bottom of the front end of the conveyor frame, and heating elements mounted on the inner walls of both sides of the conveyor frame.

[0007] Preferably, the heating element includes a heating frame, which is bolted to the inner wall of the conveyor frame. The bottom of the heating frame has an arc-shaped surface, and a heating rod is installed in the arc-shaped surface.

[0008] Preferably, aluminum foil is adhered to the curved surface.

[0009] Preferably, the top of the conveyor frame is bolted with a cover plate, and a breathable mesh plate is provided in the middle of the cover plate.

[0010] Preferably, the interior of the feed box consists of a storage chamber and a discharge chamber, and the discharge chamber is connected to the interior of the conveyor frame.

[0011] Preferably, the bottom of the storage chamber is inclined, and a metering roller is rotatably installed on the top of the discharge chamber. The metering roller has a metering groove, and the output end of the second motor is connected to the metering roller.

[0012] This utility model provides a pre-drying device for quartz sand raw materials. It has the following beneficial effects:

[0013] (1) This utility model uses a conveying component inside the conveying frame to transport quartz sand. The spiral blades and actuating rod in the conveying component can make the quartz sand move forward in a spiral shape inside the conveying frame, which can make the quartz sand stay in the drying area for a longer time, thus ensuring sufficient drying time.

[0014] (2) The present invention uses a lever that is equidistantly arranged on the surface of the spiral blade to continuously move the quartz sand during the conveying process, so that the quartz sand can come into full contact with the hot air, thereby improving the drying effect.

[0015] (3) By setting a quantitative roller and a quantitative groove in the feed box, the quantitative groove on the quantitative roller can accurately control the amount of quartz sand raw material entering the conveyor frame each time, so as to avoid the drying effect and production efficiency being affected by too much or too little feed.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Example 1:

[0027] Please see Figure 1-5 This utility model provides a pre-drying device for quartz sand raw materials, including a support 1, a conveyor frame 2 fixedly installed on the top of the support 1, a first motor 21 installed at the rear end of the conveyor frame 2, a conveying component 23 installed inside the conveyor frame 2, the conveyor component 23 including a rotating shaft 232, the rotating shaft 232 being rotatably installed in the conveyor frame 2, and the rotating shaft 232 being connected to the output end of the first motor 21, a spiral blade 231 fixedly installed on the rotating shaft 232, actuating rods 233 being equidistantly arranged on the surface of the spiral blades 231, the actuating rods 233 being spirally arranged along the surface of the spiral blades 231, a feed box 4 installed at the rear end of the conveyor frame 2, an output pipe 22 connected to the bottom of the front end of the conveyor frame 2, and heating elements 24 being arranged on the inner walls of both sides of the conveyor frame 2;

[0028] The heating element 24 includes a heating frame 241, which is bolted to the inner wall of the conveyor frame 2. The bottom of the heating frame 241 is provided with an arc-shaped surface 243, and a heating rod 242 is installed in the arc-shaped surface 243.

[0029] Aluminum foil is attached to the curved surface 243;

[0030] The top of the conveyor frame 2 is bolted with a cover plate 3, and a breathable mesh plate 31 is provided in the middle of the cover plate 3.

[0031] Specifically, during operation, the quartz sand raw material is placed into the feed box 4, which is connected to the conveyor frame 2, allowing the quartz sand to fall into the conveyor frame 2. After the first motor 21 starts, it drives the rotating shaft 232 of the conveyor component 23 to rotate, and the spiral blades 231 fixed on the rotating shaft 232 rotate accordingly. The rotation of the spiral blades 231 pushes the quartz sand forward within the conveyor frame 2, allowing the quartz sand to remain in the drying area for a longer time, thus ensuring sufficient drying time.

[0032] During the quartz sand conveying process, the heating elements 24 on both sides of the inner wall of the conveyor frame 2 begin to work. The heating rods 242 in the arc-shaped surface 243 at the bottom of the heating frame 241 of the heating element 24 are energized and generate heat. The aluminum foil has good reflective properties, which can reflect the heat generated by the heating rods 242 back into the conveyor frame 2, reducing the heat loss to the outside of the conveyor frame 2. This allows more heat to be retained inside the conveyor frame 2 for heating the air, improving the heat utilization rate and helping to create a hot air environment inside the conveyor frame 2 more quickly.

[0033] The spiral blades 231 have spirally arranged actuating rods 233 that continuously agitate the quartz sand, causing it to tumble as it moves forward. This prevents uneven drying caused by excessive local accumulation. Quartz sand that was originally in the lower layer and had difficulty contacting the hot air can also be moved to the upper layer, thus making full contact with the hot air generated by the heating element 24, improving the overall uniformity of drying, and resulting in a more uniform and thorough drying effect.

[0034] During the drying process, the moisture in the quartz sand evaporates, forming water vapor. The permeable mesh plate 31 in the middle of the top cover plate 3 of the conveyor frame 2 allows the water vapor to escape from the conveyor frame 2, preventing water vapor from accumulating inside the conveyor frame 2 and affecting the drying effect. Finally, the dried quartz sand is discharged from the output pipe 22 at the bottom front end of the conveyor frame 2.

[0035] Furthermore, to avoid excessive material entering the conveyor rack 2, please refer to [the relevant documentation / reference]. Figure 1-5 The inside of the feed box 4 is composed of a storage chamber 41 and a discharge chamber 42, and the discharge chamber 42 is connected to the inside of the conveyor frame 2.

[0036] The bottom of the storage chamber 41 is inclined, and a metering roller 43 is rotatably installed on the top of the discharge chamber 42. A metering groove 45 is opened on the metering roller 43, and the output end of the second motor 44 is connected to the metering roller 43.

[0037] Specifically, the quartz sand raw material is first placed into the storage chamber 41 of the feed box 4. Since the bottom of the storage chamber 41 is inclined, the quartz sand will naturally slide towards the discharge chamber 42 under gravity. A metering roller 43 is rotatably mounted on the top of the discharge chamber 42, and a metering groove 45 is opened on the metering roller 43. The metering roller 43 is connected to the output end of the second motor 44. The second motor 44 drives the metering roller 43 to rotate. When the metering groove 45 rotates to align with the bottom of the storage chamber 41, the quartz sand will fall into the metering groove 45. As the metering roller 43 continues to rotate, the metering groove 45 containing quartz sand rotates to a position communicating with the discharge chamber 42 and the conveyor frame 2. At this time, the quartz sand in the metering groove 45 will fall into the conveyor frame 2. Since the volume of the metering groove 45 is fixed, the amount of quartz sand that can be accommodated and conveyed each time it rotates is also fixed. This ensures that the amount of raw material entering the conveyor frame 2 is controllable, avoiding excessive raw material entering the conveyor frame 2 at once.

[0038] By precisely controlling the amount of raw material entering the conveyor frame 2, it can be ensured that the quartz sand has sufficient space within the conveyor frame 2 to contact the heating element 24, allowing hot air to fully surround each quartz sand particle, thus guaranteeing the uniformity and thoroughness of drying. If there is too much raw material, it will cause the quartz sand to accumulate, and some quartz sand will not be able to effectively contact the hot air, affecting the drying effect.

[0039] Working principle: Quartz sand raw material is placed in the storage chamber 41 of the feed box 4. Because the bottom of the storage chamber 41 is inclined, the quartz sand will slide towards the discharge chamber 42 under the action of gravity. The second motor 44 is started, which drives the metering roller 43 at the top of the discharge chamber 42 to rotate. When the metering groove 45 on the metering roller 43 rotates to be aligned with the bottom of the storage chamber 41, the quartz sand falls into the metering groove 45. As the metering roller 43 continues to rotate, the metering groove 45 containing quartz sand rotates to the position where it connects with the discharge chamber 42 and the conveyor frame 2, and the quartz sand in the metering groove 45 falls into the conveyor frame 2.

[0040] The first motor 21 is turned on, which drives the rotating shaft 232 of the conveyor 23 to rotate. The spiral blades 231 fixed on the rotating shaft 232 rotate accordingly, pushing the quartz sand forward in the conveyor frame 2. At the same time, the heating elements 24 on the inner walls of both sides of the conveyor frame 2 start to work. The heating rods 242 in the arc-shaped surface 243 at the bottom of the heating frame 241 are energized and generate heat. The aluminum foil attached to the arc-shaped surface 243 reflects the heat back into the conveyor frame 2, reducing heat loss and quickly creating a hot air environment inside the conveyor frame 2 to dry the quartz sand. The agitator rods 233 on the surface of the spiral blades 231 continuously agitate the quartz sand, causing it to tumble continuously as it moves forward, preventing excessive local accumulation and ensuring that the quartz sand originally in the lower layer can also fully contact the hot air, improving the uniformity of drying.

[0041] During the drying process, the moisture in the quartz sand evaporates to form water vapor. The breathable mesh plate 31 in the middle of the top cover plate 3 of the conveyor frame 2 allows the water vapor to be discharged. The fully dried quartz sand is discharged from the output pipe 22 at the bottom front end of the conveyor frame 2, completing the entire pre-drying process.
