Description

A scraper type sand float washing machine

technical field

The invention belongs to the technical field of sand making machinery and equipment, and relates to a scraper type sand floating washing machine.

Background technique

Sand washing machine is a kind of construction machinery equipment used to remove impurities in sand products. It is used for cleaning materials in sand and gravel fields, mines, building materials, transportation, chemical industry, water conservancy and hydropower, concrete mixing stations and other industries. . Existing sand washing machines generally adopt a drum-type structure, and the drums are used to continuously wash sand and gravel in the water tank to achieve the purpose of cleaning. The existing sand washing machines can only clean sand with a small quality, and the cleaning volume is large or the quality is large. When there is too much sand, it is easy to cause the drum to be stuck, and the cleaning effect of the sand washing machine is not ideal. Glue on the attachments.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art , the present invention provides a scraper type sand and gravel floating washing machine with the characteristics of simple structure, convenient operation and maintenance, large output, high efficiency, low energy consumption and large particle size range of treated materials.

The technical solution adopted by the present invention to solve the technical problem is: a scraper type sand float washing machine, including a water tank, a driven wheel with one end wrapped around the bottom of one side of the water tank is arranged in the water tank, and the other end is connected to the bottom of the water tank. The upper drive wheels are connected and capable of reciprocating crawler belts. Holes for sand and gravel to fall down are arranged on the crawler belts, and scrapers are arranged at the lower end of each hole.

The upper end of the side of the water tank and the driven wheel is provided with a feed inlet capable of limiting the falling position of sand and gravel so that the sand and gravel will not fall to the bottom of the water tank.

The drive wheel is fixed on the bottom of the water tank through a limit shaft and bearings on both sides.

The driving wheel is connected with the motor through a transmission device.

A baffle plate for blocking the floating objects from floating upward is provided at the upper end of the crawler belt in the direction of downward transportation, and a floating object outlet is provided at the water tank on the side close to the baffle plate.

The lower end of the crawler belt in the direction of upward transportation is provided with a water tank that is covered with the crawler belt and communicates with the external water tank.

The beneficial effects of the present invention are: the sand enters the water tank through the feed port, the attachments on the sand are separated from the sand by the action of water, the attachments float upward, the sand falls from top to bottom, and falls from the pores in the track. into the water tank at the lower end of the upward moving crawler belt, through the action of the scraper installed on the crawler belt, the scraper continuously scrapes and washes the sand and gravel, and continuously drives the sand and gravel upward while scraping and washing, because the floating objects will be removed by the block The board blocks and flows out directly through the floating object outlet. During the entire scraping and washing process, the trajectory of the attachment and the material is separated. Since the floating washing machine is transported by the crawler belt, the floating washing machine can clean larger stones and can complete The cleaning of sand and gravel below 200mm is very suitable for cleaning materials with a lot of attachments, such as cleaning and recycling of construction waste. It has the advantages of simple structure, clean cleaning, convenient operation and maintenance, large output, high efficiency, and low energy consumption. Wide range of features.

Description of drawings

Fig. 1 is a schematic diagram of the structure of the present invention.

In the figure: 1-feed inlet, 2-driven wheel, 3-drive wheel, 4-track, 5-scraper, 6-motor, 7-baffle plate, 8-float outlet, 9-water tank.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Referring to Fig. 1, a scraper 5-type gravel floating washing machine includes a water tank, and a feeding port 1 that can limit the falling position of the sand and gravel so that the sand and gravel will not fall to the bottom of the water tank is provided at the upper end of the water tank. There is a driven wheel 2 with one end wrapped around the bottom of one side of the water tank and fixed to the bottom of the water tank through the limit shaft and bearings on both sides, and the other end is connected with the driving wheel 3 above one side of the water tank, capable of reciprocating motion The crawler belt 4 is provided with holes for sand and gravel to fall downward on the crawler belt 4, and a scraper 5 is provided at the lower end of each hole. A baffle 7 is provided at the upper end of the direction of downward transportation to block the floating objects from floating upwards, a floating object outlet 8 is provided at the water tank on the side close to the baffle 7, and a cover is provided at the lower end of the crawler belt 4 in the direction of upward transportation. There is a water tank 9 which is synchronized with the crawler belt 4 and communicates with the external water tank.

The sand and gravel enter the water tank through the feed port, and the attachments on the sand and gravel are separated from the sand and gravel by the action of water. The attachment floats upwards, and the sand and gravel fall from top to bottom, and fall from the pores in the track to the bottom of the upward moving track. In the water tank, through the function of the scraper installed on the track, the scraper continuously scrapes and washes the sand and gravel, and continuously drives the sand and gravel upward while scraping and washing, because the floating objects will be blocked by the baffle and directly pass through the floating objects The outlet flows out. During the whole scraping and washing process, the trajectory of attachments and materials is separated. Since the floating washing machine is transported through the crawler belt, the floating washing machine can clean larger stones and complete the cleaning of sand and gravel below 200mm. , very suitable for cleaning materials with a lot of attachments, such as cleaning and recycling of construction waste. It has the characteristics of simple structure, clean cleaning, convenient operation and maintenance, large output, high efficiency, low energy consumption and large particle size range of processing materials.
