Description

Technical Field

[0001] This utility model relates to the field of quartz sand production technology, specifically to a high-purity quartz sand cooling device. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral.

[0003] Quartz sand generates high temperatures during processing such as crushing, grinding, calcination, or modification. If these temperatures are not effectively cooled, they may affect subsequent processes and product quality. Currently, after processing, the internal temperature of quartz sand rises, and it is usually allowed to cool naturally by standing still. However, the cooling rate is relatively slow and inconvenient for subsequent work.

[0004] Therefore, in order to solve the above problems, this utility model provides a high-purity quartz sand cooling device. Utility Model Content

[0005] The purpose of this invention is to provide a high-purity quartz sand cooling device. This device has a simple structure and can achieve continuous cooling of high-purity quartz sand, thereby improving cooling efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-purity quartz sand cooling device, characterized in that: it includes a conveying mechanism, the conveying mechanism comprising two parallel fixed frames and several rollers, the several rollers being parallel to each other and longitudinally arranged between the two fixed frames, a conveyor belt being provided on the several rollers, and the quartz sand moving forward along the rollers in a directional manner, characterized in that: a support frame is provided under the two fixed frames, a driving mechanism for driving the conveyor belt forward is provided between the support frame and the fixed frames, a limiting fixed baffle is provided on the two fixed frames, a feed scraper and several air duct assemblies are sequentially arranged between the two limiting fixed baffles, and a discharge port is provided at the tail of the two fixed frames.

[0007] As a further embodiment of this invention: the feed scraper is inclinedly positioned between two limiting and fixing baffles along the forward directional movement direction of the quartz sand. The two limiting and fixing baffles are equipped with slide rails for fixing the feed scraper, and these slide rails are symmetrically arranged on the two limiting and fixing baffles. This slide rail configuration allows for convenient replacement of the feed scraper.

[0008] As a further embodiment of this invention: Two sets of slide rails are provided, inclinedly positioned on the side of the two limiting and fixing baffles near the conveyor belt. The higher end of the slide rail is the entry point for the feed scraper to slide into the slide rail, and the lower end is the height of the feed scraper from the conveyor belt. There is a height difference between the lower ends of the two sets of slide rails. By having two sets of slide rails with a height difference between the lower ends and the conveyor belt, the position of the feed scraper on the slide rail can be adjusted as needed to control the thickness of the quartz sand conveyed on the conveyor belt, adapting to quartz sand at different temperatures.

[0009] As a further embodiment of this invention: the plurality of duct assemblies includes a fixed pipe and a plurality of air inlets. The fixed pipe is disposed between two limiting and fixing baffles, and the plurality of air inlets are evenly distributed below the fixed pipe, with the air outlets of the air inlets aligned with the conveyor belt. The plurality of duct assemblies are evenly distributed side by side between the two limiting and fixing baffles. The arrangement of the plurality of duct assemblies allows for continuous airflow cooling of the quartz sand on the conveyor belt, improving cooling efficiency.

[0010] As a further aspect of this invention: the plurality of duct assemblies are divided into odd-numbered rows and even-numbered rows. A first fan and a second fan are disposed between the support frame and the fixed frame. The fixed pipes in the odd-numbered rows of duct assemblies are connected to the air outlet of the first fan via ventilation ducts, and the fixed pipes in the even-numbered rows of duct assemblies are connected to the air outlet of the second fan via ventilation ducts. By configuring the duct assemblies to connect the first fan and the second fan, the frequency of continuous air blowing for cooling the quartz sand can be adjusted according to the temperature requirements of the quartz sand.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The system has two sets of slide rails, with a height difference between the lower end of each set and the conveyor belt. The thickness of the quartz sand conveyed on the conveyor belt can be controlled by changing the position of the feed scraper on the slide rail as needed, which can adapt to quartz sand at different temperatures.

[0013] By setting up several duct assemblies, continuous air blowing cooling can be achieved for the quartz sand, improving cooling efficiency. The structure connecting the first and second fans to these duct assemblies allows the frequency of continuous air blowing cooling to be adjusted according to the temperature requirements of the quartz sand.

[0018] 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.

[0019] Please see Figures 1-3 As shown, this utility model provides the following technical solution: a high-purity quartz sand cooling device, including a conveying mechanism, the conveying mechanism including two parallel fixed frames and several rollers, the several rollers being parallel to each other and longitudinally arranged between the two fixed frames, a conveyor belt 9 being arranged on the several rollers, and the quartz sand moving forward in a directional direction along the rollers, characterized in that: a support frame 5 is arranged under the two fixed frames, a driving mechanism for driving the conveyor belt 9 forward is arranged between the support frame 5 and the fixed frames, a limiting fixed baffle 1 is arranged on the two fixed frames, a feed scraper 2 and several air duct assemblies are arranged sequentially between the two limiting fixed baffles 1, and a discharge port 6 is arranged at the tail of the two fixed frames.

[0020] The feed scraper 2 is inclined between two limiting and fixing baffles 1 along the forward directional movement direction of the quartz sand. The two limiting and fixing baffles 1 are provided with slide rails 10 for fixing the feed scraper 2. The slide rails 10 are symmetrically arranged on the two limiting and fixing baffles 1. The feed scraper 2 can be easily replaced by the slide rails 10.

[0021] Two sets of slide rails 10 are provided, and the two sets of slide rails 10 are inclinedly set on the side of the two limiting and fixing baffles 1 near the conveyor belt 9. The higher end of the slide rail 10 is the entry end where the feed scraper 2 slides into the slide rail 10, and the lower end is the height of the feed scraper 2 from the conveyor belt 9. There is a height difference between the lower ends of the two sets of slide rails 10. By providing two sets of slide rails 10 with a height difference between the lower ends of the two sets of slide rails 10 and the conveyor belt 9, the position of the feed scraper 2 on the slide rail 10 can be changed as needed to control the thickness of the quartz sand conveyed on the conveyor belt 9, which can adapt to quartz sand at different temperatures.

[0022] The plurality of duct assemblies include a fixed pipe 3 and a plurality of air inlets 4. The fixed pipe 3 is disposed between two limiting and fixing baffles 1, and the plurality of air inlets 4 are evenly distributed below the fixed pipe 3, with the air outlets of the air inlets 4 aligned with the conveyor belt 9. The plurality of duct assemblies are evenly distributed side by side between the two limiting and fixing baffles 1. The arrangement of the plurality of duct assemblies allows for continuous air blowing and cooling of the quartz sand on the conveyor belt 9, improving cooling efficiency.

[0023] The duct assemblies are divided into odd-numbered and even-numbered rows. A first fan 7 and a second fan 8 are arranged between the support frame 5 and the fixed frame. The fixed pipe 3 in the odd-numbered row duct assembly is connected to the air outlet of the first fan 7 through a ventilation duct, and the fixed pipe 3 in the even-numbered row duct assembly is connected to the air outlet of the second fan 8 through a ventilation duct. By connecting the duct assemblies to the first fan 7 and the second fan 8, the frequency of continuous air blowing for cooling the quartz sand can be changed according to the temperature requirements of the quartz sand.

[0024] In use, the quartz sand to be cooled is placed on the conveyor belt 9, and the feed scraper 2 is installed on a set of slide rails 10 as needed. The conveyor belt 9 is driven forward by the drive mechanism, thereby causing the quartz sand to move forward in a directional manner. The first fan 7 and the second fan 8 are turned on, and the quartz sand on the conveyor belt 9 is continuously cooled by air blowing as it passes under the air diffuser 4. The quartz sand that has been continuously cooled is discharged and collected through the discharge port 6.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
