Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a sand washing machine for concrete production. Background Technology

[0002] Concrete production is the process of mixing raw materials such as cement, aggregates (such as sand and stone), and water in a certain proportion, and then using processes such as stirring and curing to make artificial stone. Sand washing machines are mechanical equipment used to clean sand and gravel, remove surface impurities, and dehydrate them. They are one of the indispensable pieces of equipment in concrete production.

[0003] Patent CN221209152U discloses a sand washing machine for concrete production, which includes a base; a washing chamber detachably connected to the base, one end of which is connected to multiple drain pipes through a sealing sleeve, and the drain pipes are equipped with regulating valves; and four sets of electro-hydraulic actuators, which are arranged in pairs. The overall structure of this device is relatively simple, which facilitates the washing of sand and gravel. Moreover, compared with the prior art, it saves more water resources, has better water-saving performance, and is more practical and conducive to widespread use.

[0004] However, the existing device involves guiding sand and gravel into a screening bucket and then using an electric push rod and mounting plate to send it into the washing chamber. In this way, the surface of the sand and gravel washed out will inevitably be covered with mud. At the same time, the sand and gravel washing process must be stopped during the removal of the sand and gravel, which affects the washing efficiency. Therefore, a sand washing machine for concrete production is proposed to solve the problem that existing sand washing machines are difficult to clean and discharge sand and gravel conveniently.

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.

[0023] Example: Please refer to Figure 1-4 A sand washing machine for concrete production includes a machine body 1, with a washing chamber 2 inclined inside the machine body 1. A feed inlet 3 is located at the top of the machine body 1. A fixed plate 4 is symmetrically and fixedly connected to one side of the machine body 1. Rotary rollers 5 are installed between the inner cavity of the washing chamber 2 and the fixed plate 4. A perforated conveyor belt 6 is installed around the outer ring of each roller 5. The rollers 5 are positioned between the washing chamber 2 and the fixed plate 4 via a first rotating shaft 7. A scraping mechanism 8 is installed between the fixed plates 4. The inner cavity of the sand washing machine 1 is equipped with three cams 9. The cams 9 are set in the inner cavity of the washing chamber 2 through the second rotating shaft 10. One end of the sand washing machine body 1 is fixedly connected to the motor 11. The other end of the sand washing machine body 1 is equipped with a first large sprocket 12 and a first small sprocket 13. The first large sprocket 12 and the first small sprocket 13 are connected by a first chain 14. The top of the inner cavity of the washing chamber 2 is equipped with a water spraying mechanism 15. The bottom of the fixed plate 4 is equipped with a collection box 16. The top of the washing chamber 2 is fixedly connected with a guide plate 19.

[0024] Furthermore, the first rotating shaft 7 passes through the sand washing machine body 1 and is fixedly connected to the first large sprocket 12, the second rotating shaft 10 passes through the sand washing machine body 1 and is fixedly connected to the first small sprocket 13, the output shaft of the motor 11 is fixedly connected to the first rotating shaft 7 that passes through the cleaning chamber 2, the cam 9 contacts the inner surface of the perforated conveyor belt 6, the perforated conveyor belt 6 is inclinedly arranged in the inner cavity of the cleaning chamber 2, the rotation of the cam 9 that contacts the inner surface of the perforated conveyor belt 6 generates a periodic pushing force, thereby causing the perforated conveyor belt 6 to vibrate, and at the same time, without affecting the conveying of sand and gravel, the inclined arrangement of the perforated conveyor belt 6 is also conducive to the discharge of washing water.

[0025] Furthermore, the cleaning mechanism 8 includes a scraper 801 fixedly connected between the fixed plates 4. The top of the scraper 801 contacts the perforated conveyor belt 6. The surface of the scraper 801 is smooth and a roller brush 802 is provided on the side facing the sand washing machine body 1. The roller brush 802 is arranged between the fixed plates 4 through a third rotating shaft 803 and is in contact with the perforated conveyor belt 6.

[0026] Furthermore, a second large sprocket 804 is provided at one end of the sand washing machine body 1, and a second small sprocket 805 is provided at one end of the fixed plate 4. The second large sprocket 804 and the second small sprocket 805 are connected by a second chain 806. A second rotating shaft 10 passes through the sand washing machine body 1 and is connected to the second large sprocket 804. A third rotating shaft 803 passes through the fixed plate 4 and is connected to the second small sprocket 805. The sand and gravel on the perforated conveyor belt 6 are spread evenly, and the washed sand and gravel will eventually fall into the collection box at the bottom of the fixed plate 4. In section 16, the sand and gravel are collected and, in conjunction with scraper 801, can be scraped off the sand and gravel adhering to the bottom side of the perforated conveyor belt 6. Under the action of the second large sprocket 804, the second small sprocket 805, and the second chain 806, the third rotating shaft 803 is driven to rotate rapidly, which in turn drives the roller brush 802, which is in contact with the bottom of the perforated conveyor belt 6, to rotate rapidly as well, thereby further scraping off the sand and gravel adhering to the perforated conveyor belt 6, ensuring that all the sand and gravel after washing is discharged and avoiding waste.

[0027] Furthermore, the water spraying mechanism 15 includes water spraying pipes 151 symmetrically arranged at the top of the inner cavity of the cleaning chamber 2, a nozzle 152 is provided at the bottom of the water spraying pipes 151, and a water inlet pipe 153 is provided at the top of the sand washing machine body 1.

The water pipe is connected to the water inlet pipe 153, and then the water is introduced into the spray pipe 151. Then, the water is sprayed out from the nozzle 152 onto the sand and gravel laid flat on the perforated conveyor belt 6. The mud and water generated by washing passes through the perforated conveyor belt 6 and finally flows into the bottom of the washing chamber 2 for unified collection. Then, the valve 18 is opened to discharge the collected mud and water from the drain pipe 17 for recycling and treatment, thereby improving the water resource utilization rate.

[0029] Working principle: When using this concrete production sand washing machine, the sand and gravel to be washed are introduced into the feed inlet 3, and the guide plate 19 is used to make the sand and gravel slide onto the perforated conveyor belt 6. At the same time, the water spraying mechanism 15 sprays water into the washing chamber 2, and the motor 11 is turned on to use the rotating roller 5 and the first rotating shaft 7 to transport the sand and gravel to the right. During the process, the first large sprocket 12, the first small sprocket 13 and the first chain 14 are used to drive the cam 9 on the second rotating shaft 10 to rotate quickly, thereby making the perforated conveyor belt 6 vibrate, so as to spread the sand and gravel evenly on the perforated conveyor belt 6 for washing and discharge, which solves the problem that existing sand washing machines are difficult to clean and discharge sand and gravel conveniently.
