Dust-proof gravel production system

Abstract

A dust-proof sand and gravel production system, including a feeder, a jaw crusher, an impact crusher, a vibrating screen, a sand making machine and a sand belt, the feeder is connected to the jaw crusher, and the jaw crusher is connected to the Impact crusher, the impact crusher is connected to the vibrating screen, the vibrating screen is connected to the sand making machine, and the sand making machine is connected to the sand belt; the sand making machine is equipped with a water mist fan, and the water mist fan blows to the sand making machine when the sand making machine is working. The outlet is sprayed with water mist. After the implementation of the present invention, it can effectively reduce the dust generated by factors such as broken stones, transshipment, vibration, etc. in the sand and gravel production process, and the structure is relatively simple. Small-scale sand and gravel plants can also be well applied in large-scale sand and gravel plants. It can not only protect the health of operators, but also reduce pollution and protect the ecological environment around the manufacturer. In addition, the present invention has low layout costs , can be widely promoted.

Description

technical field [0001] The invention belongs to the field of building raw material manufacturing, relates to the manufacture of sand and gravel, in particular to a dust-proof sand and gravel production system. Background technique [0002] At present, in the sand and gravel manufacturing process, a large amount of dust is often generated due to factors such as crushing stones, transfer, vibration, etc., and the existing sand making systems generally do not perform dust removal treatment in the manufacturing process of crushed sand, so that the sand making The environment is extremely deteriorating, endangering the health of on-site workers. In order to prevent the dust from flying, some enterprises seal the conveying mechanisms such as belt conveyors in the screening machine and vibrating screen, and finally collect the dust with filters, etc., but this method has low dust removal efficiency and complicated structure, which makes sand making Equipment costs are higher.

[0002] At present, in the sand and gravel manufacturing process, a large amount of dust is often generated due to factors such as crushing stones, transfer, vibration, etc., and the existing sand making systems generally do not perform dust removal treatment in the manufacturing process of crushed sand, so that the sand making The environment is extremely deteriorating, endangering the health of workers operating on site

In order to prevent the dust from flying, some enterprises seal the conveying mechanisms such as belt conveyors in the screening machine and vibrating screen, and finally collect the dust with filters, etc., but this method has low dust removal efficiency and complicated structure, which makes sand making High equipment cost

[0003] Chinese patent (publication number: CN104549711B) discloses a dust-proof sandstone production system. In order to extract the dust in sandstone manufacturing, each machine is connected through a seal, a special absorption device is set, and a set is set at the discharge port. The corresponding humidifier can prevent the formation of dust, but this system is only suitable for small processing plants, and the sand and gravel output is not large. The machines can be very close to each other, and it is possible to realize it in a sealed form. If it is in Large-scale production sites are not easy to realize. In addition, just installing a humidifier at the discharge port above the sand pile cannot prevent the dust generated during the sand and gravel production process. There will still be a lot of dust in the production and manufacturing environment. Existence, endangering the health of operating workers
