[0002] Quartz sand is quartz particles made by crushing quartz stone. It is a silicate mineral with hardness, wear resistance and stable chemical properties. The production process of quartz sand is as follows: crush the quartz stone and process it into quartz sand particles of corresponding specifications according to customer requirements, and then flotation, water washing, acid washing, deacidification water washing, dehydration, drying, cooling, screening and magnetic separation are carried out on the processed quartz sand particles in sequence.

[0003] However, when cooling the quartz sand after drying, the dried quartz sand is usually transported to a silo; currently, the silo used to cool the quartz sand includes a silo body, a feed port is provided at the top of the silo body, a discharge port is provided at the bottom of the silo body, and a control valve is provided at the discharge port. Before the dried quartz sand is transported to the silo body, the control valve is first operated to close the discharge port, and then the dried quartz sand is transported to the silo body through the feed port, so that the quartz sand is naturally cooled in the silo, which results in a slower cooling efficiency of the quartz sand, thereby affecting the production efficiency of the quartz sand. Utility Model Content

[0004] The present application provides a quartz sand cooling silo to improve the cooling efficiency of quartz sand, thereby improving the production efficiency of quartz sand.

[0005] The technical solution adopted in this application is:

[0007] By adopting the above technical scheme, when using the quartz sand cooling silo, the opening and closing door is first moved to the closed position, and then the opening and closing door closes the discharge port, and then the dried quartz sand is transported to the silo through the feed port, and cold air is transported to the cooling pipe at the same time. Since the cooling pipe is penetrated through the silo, the dried quartz sand will contact the cooling pipe after entering the silo, and when the quartz sand is reduced to the set temperature, the opening and closing door is driven toward the open position, so that the opening and closing door opens the discharge port, and the quartz sand in the silo is discharged through the discharge port; when cooling the quartz sand, the cold air introduced into the cooling pipe exchanges heat with the quartz sand through the cooling pipe, so as to shorten the time required for cooling the quartz sand, thereby improving the cooling efficiency of the quartz sand, and then improving the production efficiency of the quartz sand; at the same time, the provision of the cooling pipe can also increase the structural strength of the silo, so as to increase the service life of the quartz sand cooling silo.

[0008] Optionally, the warehouse body has a windward side and a leeward side opposite to the windward side, and the cooling pipe has an air inlet located on the side where the windward side is located and an air outlet located on the side where the leeward side is located.

[0009] By adopting the above technical solution, a ventilation system is usually set up in the factory building for producing quartz sand, and when placing the quartz sand cooling silo, the windward side can be placed on the side that caters to the air flow direction of the factory building, so that the airflow in the factory building automatically enters the cooling pipe through the air inlet pipe, so as to avoid the need to use special equipment to provide cold air for the cooling pipe, thereby reducing the cooling cost of the quartz sand while ensuring the cooling efficiency of the quartz sand.

[0010] Optionally, the air inlet pipe opening is arranged flush with the side surface of the windward side.

[0011] By adopting the above technical solution, since the air inlet pipe opening is arranged flush with the side of the windward side, the airflow generated by the ventilation system can directly enter the cooling pipe through the air inlet pipe opening after hitting the side of the windward side, thereby reducing the difficulty of the airflow in the factory building entering the cooling pipe through the air inlet pipe opening, so that more cold air can enter the cooling pipe, thereby further improving the cooling efficiency of the quartz sand, and further improving the production efficiency of the quartz sand.

[0012] Optionally, the cooling pipe is arranged to be inclined upward along the direction from the windward side to the leeward side.

[0013] By adopting the above technical solution, since the cooling pipe is inclined upward from the windward side to the leeward side, the length of the cooling pipe is increased, thereby increasing the flow path of the cold air in the cooling pipe, thereby increasing the heat exchange time between the cold air and the quartz sand, and then increasing the cooling efficiency of the cold air on the quartz sand, so as to further improve the cooling efficiency of the quartz sand and further improve the production efficiency of the quartz sand.

[0014] Optionally, a plurality of cooling pipes are provided and are divided into multiple layers along the vertical direction, and the cooling pipes of two adjacent layers are staggered.

[0015] By adopting the above technical solution, since multiple cooling pipes are provided and divided into multiple layers in the vertical direction, the cooling points of the quartz sand are increased, and at the same time, the amount of cold air that can exchange heat with the quartz sand is increased to improve the cooling efficiency of the quartz sand, thereby reducing the time required for cooling the quartz sand, and further improving the production efficiency of the quartz sand.

[0016] Optionally, a slide rail is provided at the bottom of the warehouse body, and the opening and closing door is slidably connected to the slide rail, so that when the opening and closing door slides back and forth along the slide rail, the opening and closing door moves between the open position and the closed position.

[0017] By adopting the above technical solution, since the opening and closing door is slidably connected to the slide rail, when opening or closing the material outlet, it is only necessary to slide the opening and closing door, thereby reducing the difficulty of operating the opening and closing door, so as to achieve the effect of facilitating the opening or closing of the material outlet. At the same time, compared with the solution of opening the opening and closing door by rotating, the stability of the opening and closing door when closing the material outlet is increased, so as to increase the closing effect of the opening and closing door on the material outlet.

[0018] Optionally, one end of the slide rail is extended toward the outside away from the warehouse body and forms an opening section, and the opening section is provided with a driving member acting on the opening and closing door.

[0019] By adopting the above technical solution, when the discharge port is opened or closed, the driving component is started, and the driving component drives the opening and closing door to slide along the slide rail, and then the opening and closing door moves from the open position to the closed position or from the closed position to the open position, so as to realize the automatic movement of the opening and closing door. In this process, the need for manual operation is avoided, thereby reducing the workload of the staff and realizing the automatic opening or closing of the discharge port.

[0020] Optionally, the opening and closing door is provided with a sealing sheet corresponding to the slide rail, and when the opening and closing door is in the open position, the sealing sheet is located in the slide rail corresponding to the bottom of the discharge port.

[0021] By adopting the above technical solution, when the opening and closing door moves from the closed position to the open position under the action of the driving member, the opening and closing door drives the sealing plate to move, and then the sealing plate moves to the slide rail corresponding to the bottom of the discharge port, so that the sealing plate seals the gap between the slide rail and the discharge port, so as to avoid the situation where the quartz sand is stuck in the gap between the slide rail and the discharge port when it falls, causing the opening and closing door to be unable to move from the open position to the closed position, so as to ensure the normal closure of the discharge port by the opening and closing door.

[0022] Optionally, the top of the bin body is open to form the feed port, and a sealing cover is provided at the feed port, wherein the sealing cover has a central hole for a conveying pipe to pass through.

[0023] By adopting the above technical scheme, since the top of the silo is open and a feed port is formed to increase the area of ​​the feed port, it is convenient to inspect and repair the quartz sand cooling silo and install the cooling pipe. At the same time, a sealing cover is provided at the feed port, which can seal the feed port to prevent external dirt from entering the silo, thereby ensuring the cleanliness of the quartz sand.

[0024] Optionally, a reinforcing rib is provided on a side of the sealing cover facing away from the discharge port.

[0025] By adopting the above technical solution, reinforcing ribs are provided on the side of the sealing cover facing away from the discharge port to increase the structural strength of the sealing cover, thereby preventing the sealing cover from collapsing downward and occupying the internal space of the bin body. At the same time, the sealing performance of the sealing cover to the feed port is increased to ensure the cleanliness of the quartz sand.

Since the cooling pipe 2 is arranged in the silo body 1, the dried quartz sand will contact the cooling pipe 2 after entering the silo body 1. When the quartz sand is reduced to the set temperature, the opening and closing door 3 is driven toward the open position so that the opening and closing door 3 can discharge the quartz sand. The outlet 12 is opened, and the quartz sand in the silo 1 is discharged through the outlet 12; when the quartz sand is cooled, the cold air passed into the cooling pipe 2 exchanges heat with the quartz sand through the cooling pipe 2, so as to greatly improve the cooling efficiency of the quartz sand, thereby shortening the time required for cooling the quartz sand, thereby improving the cooling efficiency of the quartz sand, and further improving the production efficiency of the quartz sand; at the same time, the setting of the cooling pipe 2 can also increase the structural strength of the silo 1, so as to increase the service life of the quartz sand cooling silo.

[0046] The present application does not specifically limit the manufacturing material of the cooling pipe 2. Preferably, the cooling pipe 2 is made of metal materials, such as iron, stainless steel, etc., to increase the structural strength of the cooling pipe 2, reduce the risk of damage to the cooling pipe 2, and increase the service life of the quartz sand cooling silo.

[0049] A ventilation system is usually installed in a factory building for producing quartz sand, and when placing the quartz sand cooling silo, the windward side 21 can be placed on the side that caters to the air flow direction of the factory building, so that the airflow in the factory building automatically enters the cooling pipe 2 through the air inlet pipe, thereby avoiding the need to use special equipment to provide cold air for the cooling pipe 2, thereby reducing the cooling cost of the quartz sand while ensuring the cooling efficiency of the quartz sand.

[0050] Further, see Figure 1 and Figure 2 The air inlet pipe port is arranged flush with the side of the windward side 21, so that the airflow generated by the ventilation system can directly enter the cooling pipe 2 through the air inlet pipe port after hitting the side of the windward side 21, thereby reducing the difficulty of the airflow in the factory building entering the cooling pipe 2 through the air inlet pipe port, so that more cold air can enter the cooling pipe 2, thereby further improving the cooling efficiency of the quartz sand, and further improving the production efficiency of the quartz sand.

[0051] Further, refer to Figure 1 and Figure 2 The cooling pipe 2 is arranged upwardly and tilted from the windward side 21 to the leeward side 22 to increase the length of the cooling pipe 2, thereby increasing the flow path of the cold air in the cooling pipe 2, thereby increasing the heat exchange time between the cold air and the quartz sand, and further increasing the cooling efficiency of the cold air on the quartz sand, so as to further improve the cooling efficiency of the quartz sand and further improve the production efficiency of the quartz sand.

[0052] In a preferred embodiment, referring to Figure 1 and Figure 2 There are multiple cooling tubes 2 and they are divided into multiple layers in the vertical direction, thereby increasing the cooling points of the quartz sand and increasing the amount of cold air that can exchange heat with the quartz sand, so as to improve the cooling efficiency of the quartz sand, thereby reducing the time required for cooling the quartz sand, and further improving the production efficiency of the quartz sand. The cooling tubes 2 of two adjacent layers are staggered so that the quartz sand can contact with the cooling tubes 2 of different layers during the falling process, so as to further increase the cooling efficiency of the quartz sand and further improve the production efficiency of the quartz sand.

[0053] It can be understood that each layer of cooling tubes 2 has a plurality of cooling tubes 2 , and the cooling tubes 2 in two adjacent layers of cooling tubes 2 are staggered to further increase the heat exchange position of the quartz sand.
