Description

Technical Field

[0001] This utility model belongs to the field of sand making equipment, and in particular to a humidifier for manufactured sand. Background Technology

[0002] Manufactured sand is sand and gravel produced by crushing raw materials into the required particle size using sand making equipment. Manufactured sand is usually prepared by dry method, which generates a large amount of dry dust during transportation and transfer, making it difficult to meet environmental protection requirements. In addition, when using manufactured sand to prepare concrete, it is necessary to first humidify the manufactured sand to saturate its surface with water content, so as to promote the bonding of manufactured sand with other materials, improve concrete preparation efficiency, and prevent segregation.

[0003] There are various existing humidifiers for manufactured sand. For example, CN202122504196.6 discloses a humidifier for manufactured sand that uses multi-dimensional nozzles to spray water onto the manufactured sand and simultaneously uses a turning wheel to tumble the sand to ensure uniform humidification. However, this equipment is inconvenient to remove the humidified manufactured sand during use. In addition, existing technologies such as CN202421016599.3 - a humidifier for manufactured sand processing and CN202222770105.8 also disclose humidifiers for manufactured sand processing. These existing humidifiers all humidify the manufactured sand by spraying water onto it. The humidification effect depends on the stirring effect. If the stirring is not uniform enough, it is difficult to ensure sufficient humidification, and the humidification efficiency is low. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a machine-made sand humidifier that improves the humidification effect and humidification efficiency.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a machined sand humidifier, including a water tank, an inclined feeding cylinder is provided in the water tank, a spiral conveying mechanism is provided inside the feeding cylinder, the upper end of the feeding cylinder extends outside the water tank and is connected to a discharge mechanism, the lower end of the feeding cylinder is located below the water surface and is connected to a feeding mechanism, and a plurality of radially penetrating water holes are provided on the feeding cylinder.

[0006] Furthermore, the discharge mechanism is an inclined or vertically arranged discharge pipe, and the upper end of the discharge pipe is connected to the feeding cylinder.

[0007] Furthermore, the feeding mechanism includes a feeding hopper, and a feeding pipe is provided at the lower end of the feeding hopper, the lower end of the feeding pipe being connected to the feeding cylinder.

[0008] Furthermore, the bottom cross-section of the water tank is V-shaped, and the feeding cylinder is located above the lowest point of the bottom of the water tank.

[0009] Furthermore, a water pump is installed in the water tank, and the water pump is connected to the upper inner cavity of the feeding cylinder through a water conveying mechanism.

[0010] Furthermore, the feeding cylinder includes a water immersion section, a water retention section, and a water filtration section arranged sequentially from bottom to top, with water holes disposed on the water immersion section and the water filtration section, and the water conveying mechanism communicating with the upper end of the water retention section.

[0011] Furthermore, a vertical filter cylinder is installed inside the water tank, and the water pump is installed inside the filter cylinder.

[0012] Furthermore, a liquid level monitoring mechanism is installed in the water tank, and a water replenishment mechanism is connected to the filter cylinder.

[0013] The beneficial effects of this invention are as follows: When humidifying manufactured sand using this invention, the manufactured sand is added to the lower end of the feeding cylinder through the feeding mechanism. Since the lower end of the feeding cylinder is immersed in water, the manufactured sand can also be immersed in water. The screw conveyor mechanism pushes the manufactured sand in the feeding cylinder upward, and finally discharges it from the discharge mechanism.

[0014] This invention allows for the rapid wetting of manufactured sand by immersing it in water, eliminating the need for prolonged stirring and improving humidification efficiency and effect. Furthermore, this invention enables the continuous addition and discharge of humidified manufactured sand, achieving continuous humidification. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] The mechanical sand humidifier of this utility model, such as Figure 1 and Figure 2As shown, the system includes a water tank 1, which can be made of concrete or metal, and its volume is determined according to the production volume of manufactured sand. The water tank 1 contains water of a certain depth. An inclined feeding cylinder 2 is installed inside the water tank 1. The feeding cylinder 2 is a circular metal cylinder, and a screw conveyor mechanism 3 is installed inside the feeding cylinder 2. The screw conveyor mechanism 3 is used to move the manufactured sand and specifically includes a conveying motor, a rotating shaft, and a screw conveyor plate fixedly mounted on the surface of the rotating shaft. The rotating shaft is coaxial with the feeding cylinder 2. Mounting plates can be installed at the upper and lower ends of the feeding cylinder 2. The rotating shaft is mounted on the mounting plates via bearings. The conveying motor is connected to the upper end of the rotating shaft. When the conveying motor drives the rotating shaft and the screw conveyor plate to rotate, the screw conveyor plate pushes the manufactured sand inside the feeding cylinder 2 upwards. The upper end of the feeding cylinder 2 extends beyond the water tank 1 and is connected to a discharge mechanism 4, which discharges the humidified manufactured sand. The lower end of the feeding cylinder 2 is below the water surface, i.e., the lower end of the feeding cylinder 2 is immersed in water, and the lower end of the feeding cylinder 2 is connected to a feeding mechanism 5, which conveys the dry manufactured sand into the feeding cylinder 2. The feeding cylinder 2 is provided with multiple radially penetrating water holes. The diameter of the water holes is smaller than the particle size of the manufactured sand to prevent the manufactured sand from entering the water holes. The water holes are evenly distributed on the feeding cylinder 2, and water from the water tank 1 can enter the feeding cylinder 2 through the water holes to wet the manufactured sand.

[0020] The operation process of this manufactured sand humidifier is as follows: Dry manufactured sand is continuously and uniformly added to the lower inner cavity of the feeding cylinder 2 through the feeding mechanism 5. Since the lower end of the feeding cylinder 2 is immersed in water, the manufactured sand is also immersed in water, thus wetting the manufactured sand. At the same time, the screw conveyor mechanism 3 pushes the manufactured sand in the feeding cylinder 2 to move upward at a uniform speed, thereby conveying the humidified manufactured sand to the upper end of the feeding cylinder 2, and finally discharging it from the discharge mechanism 4.

[0021] This invention allows for the rapid wetting of manufactured sand by immersing it in water, eliminating the need for prolonged stirring and improving humidification efficiency and effect. Furthermore, this invention enables the continuous addition and discharge of humidified manufactured sand, achieving continuous humidification.

[0022] In this invention, the discharge mechanism 4 is an inclined or vertically arranged discharge pipe, the upper end of which is connected to the feeding cylinder 2. A discharge port is provided at the bottom of the inner hole at the upper end of the feeding cylinder 2. The discharge pipe is made of metal and can be connected to the feeding and discharge ports by bolts or welded to the discharge port.

[0023] In this invention, the feeding mechanism 5 includes a feeding hopper 51, which is frustum-shaped. A feeding pipe 52 is located at the lower end of the feeding hopper 51, and the lower end of the feeding pipe 52 is connected to the feeding cylinder 2. A feeding inlet is located at the top of the inner hole at the lower end of the feeding cylinder 2, and the lower end of the feeding pipe 52 is connected to the feeding inlet. The feeding inlet is located below the water surface, ensuring that the manufactured sand is immersed in water after entering the feeding pipe 52.

[0024] The manufactured sand contains a large number of fine particles, which easily enter the water tank 1 and form sludge. To facilitate the cleaning of this sludge, the bottom cross-section of the water tank 1 is V-shaped, and the feeding cylinder 2 is located above the lowest point of the bottom of the water tank 1. After the small particles carried by the manufactured sand enter the water tank 1, they settle to the bottom of the water tank 1. Because the bottom cross-section of the water tank 1 is V-shaped, that is, the bottom of the water tank 1 is inclined, the particles can move downwards along the bottom of the water tank 1 and eventually accumulate at the lowest position for centralized cleaning.

[0025] To further improve the humidification effect and prevent unsaturated humidification of some manufactured sand, this invention includes a water pump 6 inside the water tank 1. The water pump 6 is connected to the upper inner cavity of the feeding cylinder 2 via a water conveying mechanism 7. Under the action of the water pump 6, water in the water tank 1 flows through the water conveying mechanism 7 to the upper inner cavity of the feeding cylinder 2, and then flows downward along the feeding cylinder 2, contacting the manufactured sand in the opposite direction to further wet it. The water conveying mechanism 7 can be a water pipe.

[0026] To prevent water entering the feeding cylinder 2 through the water conveying mechanism 7 from flowing out of the water holes, the feeding cylinder 2 of this invention includes a water-immersing section 21, a water-retaining section 22, and a water-filtering section 23 arranged sequentially from bottom to top. The water-immersing section 21 is located below the water surface and is submerged in water, while the water-retaining section 22 and the water-filtering section 23 are located above the water surface. Water holes are provided on the water-immersing section 21 and the water-filtering section 23, while no water holes are provided on the water-retaining section 22. The water conveying mechanism 7 is connected to the upper end of the water-retaining section 22. After the water in the water conveying mechanism 7 enters the water-retaining section 22, it flows downward along the water-retaining section 22 to further wet the manufactured sand. When the water in the water-retaining section 22 reaches the water-immersing section 21, it returns to the water pool 1. In the water-filtering section 23, excess water in the manufactured sand can be discharged through the water holes and fall downward into the water pool 1.

[0027] After the particles carried by the manufactured sand enter the water in the pool 1, in order to prevent these particles from clogging the water pump 6 and the water conveying mechanism 7, a vertical filter cylinder 8 is installed in the pool 1, and the water pump 6 is installed inside the filter cylinder 8. The filter cylinder 8 can be made of wire mesh, which serves to filter and prevent large particles in the water from entering the water pump 6 and the water conveying mechanism 7.

[0028] To maintain a stable water level in pool 1, a level monitoring mechanism 9 is installed inside pool 1. This mechanism can utilize various existing level gauges to monitor the water level in pool 1 in real time. When the water level falls below a set value, water can be added to pool 1. The filter cartridge 8 is connected to a water replenishment mechanism 10, which can be a conventional device such as a water replenishment pipe. When adding clean water to the filter cartridge 8, the water pump 6 can draw in more impurity-free clean water, preventing clogging. Furthermore, after a period of operation, the filter holes in the filter cartridge 8 are prone to clogging. By adding water to the filter cartridge 8, excess water flows back into pool 1 through the filter holes, thus backwashing the filter holes and alleviating clogging.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
