Since some artificial sand is made by crushing stones, there is a lot of stone powder mixed in the artificial sand. The market standard for construction sand is relatively high. In order to meet the construction sand standard, the artificial sand generally needs to be cleaned. Utility Model Content

[0003] In order to solve the technical problem of machine-made sand cleaning, the utility model provides a machine-made sand cleaning device.

[0004] The utility model is implemented by the following technical scheme: a machine-made sand cleaning device, comprising an outer guard plate, on which is arranged;

[0007] Cleaning nozzles, a plurality of cleaning nozzles are arranged above the cleaning frame;

[0008] A water return tank is arranged below the cleaning frame, and a water return pipe connected to the cleaning nozzle is arranged on one side of the water return tank.

[0009] Through the above technical solution, firstly, since the cleaning frame is placed at an angle and driven to move back and forth by the driving mechanism, when the machine-made sand to be cleaned is placed at the higher end of the cleaning frame, the machine-made sand moves downward along the inclined cleaning frame in coordination with the movement of the cleaning frame and the gravity of the machine-made sand itself. At this time, the machine-made sand is cleaned in coordination with the cleaning nozzle, and the cleaning water flows into the return water tank and can flow into the nozzle again for cleaning after being filtered. In actual use, a conveyor belt can be set under the cleaning frame to receive the cleaned machine-made sand.

[0010] As a further improvement of the above solution, a plurality of water leakage holes are opened at the bottom of the cleaning frame, and a fixing frame is fixedly connected to the bottom of the cleaning frame, one end of the fixing frame extends out of the outer guard plate and is connected to the driving mechanism.

[0011] Through the above technical solution, most of the cleaning water can leak through the leakage hole and be collected by the return water tank. The setting of the fixed frame makes it convenient to control the movement of the cleaning frame.

[0012] As a further improvement of the above solution, the driving mechanism includes:

[0017] Through the above technical solution, three mounting plates are provided, and a number of cleaning nozzles are installed under each mounting plate, that is, the machine-made sand passing through the cleaning frame must undergo three spray rinses to ensure the cleaning effect.

[0018] As a further improvement of the above solution, a motor is also installed on the top plate, a pulley is connected to the motor, and the pulley is movably connected to the eccentric wheel.

[0019] Through the above technical solution, the motor drives the eccentric wheel to rotate through the pulley. Because the pulley is arranged on the inner side of the outer guard plate, a protective cover (not marked in the figure) can be arranged on the outer side of the pulley.

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0034] Please combine Figure 1 - Figure 5, a machine-made sand cleaning equipment of the present embodiment includes an outer guard plate 1, and a cleaning frame 2 is arranged inside the outer guard plate 1, where the cleaning frame 2 needs to be installed at an angle. First, a fixing frame 4 is fixedly connected to the bottom of the cleaning frame 2, and a through movable hole 5 is opened at the corresponding position of the outer guard plate 1, wherein one end of the fixing frame 4 extends out of the outer guard plate 1 through the movable hole 5. In addition, a limiting plate 14 is fixedly installed on the inner wall of the outer guard plate 1, and limiting plates 14 are arranged on both sides of the cleaning frame 2, and the cleaning frame 2 is slidably installed in the limiting plate 14. Therefore, the cleaning frame 2 can only move along the direction of the movable hole 5. In addition, a plurality of leakage holes 3 are opened at the bottom of the cleaning frame 2 to facilitate the falling of cleaning water from the leakage holes 3. The diameter of the leakage hole 3 should be smaller than that of the machine-made sand to prevent the machine-made sand from falling from the leakage hole 3.

[0035] A top plate 7 is arranged above the cleaning frame 2. First, the top is fixedly connected to the outer guard plate 1. In addition, three mounting plates 8 are fixedly mounted on the top plate 7. Each mounting plate 8 is mounted with a plurality of cleaning nozzles 9. In this embodiment, five cleaning nozzles 9 are mounted on each mounting plate 8. A water inlet pipe 10 is also arranged on the top plate 7, and the water inlet pipe 10 is connected with the cleaning nozzle 9.

[0036] Since the cleaning frame 2 is installed at an angle, when the machine-made sand is placed at the higher end of the cleaning frame 2, the machine-made sand will slide down along the inclined cleaning frame 2 under the action of its own gravity. During the sliding process, the cleaning nozzles 9 installed on the three mounting plates 8 are cooperated to wash the machine-made sand.

[0037] On the basis of the above, in order to disperse the machine-made sand falling into the cleaning frame 2 and make the sandblasting and flushing of the nozzle thorough, a driving mechanism 6 is also provided on the outer guard plate 1, and the driving mechanism 6 is used to drive the cleaning frame 2 to move back and forth along the movable hole 5.

[0038] Specifically, the driving mechanism 6 includes an eccentric wheel 61 and a movable frame 62. First, the eccentric wheel 61 is movably installed on the outer wall of the outer guard plate 1. In order to drive the eccentric wheel 61 to rotate, a motor 63 is installed on the top plate 7. At the same time, the axle of the eccentric wheel 61 (not marked in the figure) passes through the outer guard plate 1. The axle is rotatably connected to the outer guard plate 1 through a bearing, and is connected to the motor 63 through a pulley 64. That is, when the motor 63 is controlled to rotate, the eccentric wheel 61 can be driven to rotate through the pulley 64. Therefore, the pulley 64 is arranged on the inner side of the outer guard plate 1. In order to avoid the machine-made sand being stuck on the pulley 64 in an accidental situation, a protective cover (not marked in the figure) can be arranged on the outer side of the pulley 64, and the protective cover can be fixedly connected to the inner wall of the outer guard plate 1.

[0039] The movable frame 62 is arranged on the outside of the eccentric wheel 61, and the bottom of the movable frame 62 is connected to the fixed frame 4 extending out of the outer guard plate 1. Because the movable frame 62 will be driven to move when the eccentric wheel 61 rotates, a limiting sleeve (not marked in the figure) is fixedly arranged on the outer guard plate 1, and the limiting sleeve provides a limiting effect for the movement of the movable frame 62. That is, when the eccentric wheel 61 rotates, the mounting frame and the cleaning frame 2 will be driven to move back and forth along the direction of the movable hole 5 through the movable frame 62. It is helpful to disperse the machine-made sand that falls into the cleaning frame 2, so that it can be easily flushed by the cleaning nozzle 9.

[0040] A large amount of water will be used in the above-mentioned flushing process. In order to reduce waste and achieve the purpose of circulating water, a return water tank 11 is provided below the cleaning frame 2, that is, part of the cleaning water will directly fall into the return water tank 11 through the water leakage hole 3 of the cleaning frame 2, and part of the water will still flow into the recovery tank from the end of the cleaning frame 2. In addition, because the cleaning water contains dust, it is necessary to install a filter 12 on one side of the recovery tank. One end of the water inlet of the filter 12 is installed in the return water tank 11, and one end of the water outlet is connected to the return water pipe 13, and the upper end of the return water pipe 13 is connected to the water inlet pipe 10 (the return water pump is not drawn in the figure). Therefore, the cleaning water falls into the return water tank 11, and after filtering, it can return to the water inlet pipe 10 to clean the machine-made sand. The purpose of saving water is achieved.

[0041] The implementation process and principle of a machine-made sand cleaning device in the embodiment of the present application are as follows:

[0042] In order to continuously clean the working steps, this embodiment can be used with two sets of feeding belts, that is, one set of feeding belts transports the machine-made sand into the cleaning frame 2, and the other set of feeding belts is arranged under the cleaning frame 2 to receive the cleaned machine-made sand. The feeding belts belong to the prior art and are not shown in this embodiment.

[0043] (I): When the feeding belt conveys the machine-made sand to the higher end of the cleaning frame 2, firstly, due to the inclined installation of the cleaning frame 2, under the action of gravity, the machine-made sand will move downward along the inclined cleaning frame 2. At this time, the cleaning nozzle 9 on the top plate 7 will spray water toward the machine-made sand to wash the machine-made sand.

[0044] At the same time, the eccentric wheel 61 is driven to rotate by the motor 63 and the pulley 64. When the eccentric wheel 61 rotates, it will push the movable frame 62 and the fixed frame 4 to move back and forth along the movable hole 5, so it can also drive the cleaning frame 2 to move back and forth. When the cleaning frame 2 moves back and forth, on the one hand, it can disperse the aggregated machine-made sand, so that the machine-made sand can be cleaned more thoroughly, avoiding the situation where the machine-made sand agglomerates and accumulates, resulting in part of the machine-made sand being unable to be effectively cleaned; on the other hand, it can accelerate the sliding of the machine-made sand from the cleaning frame 2, avoiding the machine-made sand from directly adhering to the cleaning frame 2 after it meets water.

[0045] (ii) Part of the cleaning water will fall directly into the return tank 11 through the leaking hole 3, and part of the water will still flow into the recovery tank from the end of the cleaning frame 2. The cleaning water collected in the return tank 11 can be returned to the water inlet pipe 10 after filtration through the return pipe 13 and reused, thereby achieving the purpose of saving water.

[0046] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
