A discharge valve device and concrete mixing equipment having the same

Abstract

The present invention proposes a discharge valve device and concrete mixing equipment with it, wherein the discharge valve device is used to connect the aggregate hopper and the mixing main engine, and it includes: a bucket valve assembly and a material guide groove assembly, a bucket valve The assembly is movably connected with the chute assembly, and the discharge valve device also includes: a sealing elastic gasket for sealing the side of the hopper valve assembly and the side of the chute assembly, and the elastic deformation of the sealing elastic gasket is reserved. The invention can prevent cracking, prevent water penetration and dust leakage, and improve environmental performance.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a discharge valve device and a concrete mixing device provided with it. Background technique [0002] With the rapid development of concrete mixing plants (buildings), customers are more and more pursuing product quality, and at the same time pursuing better environmental performance. When the concrete mixing plant is working normally to produce concrete, aggregates (sand, stone, water and powder, etc.) need to be poured into the mixing main engine. When the main engine starts mixing concrete, the aggregate (sand, stone) is temporarily stored in the aggregate waiting hopper , when starting to deliver the aggregate into the main machine, the aggregate passes through the discharge valve device set at the bottom of the aggregate waiting hopper, once the valve door is opened, the aggregate stored in the waiting hopper is put into the mixing main machine. The side of the existing...

Problems solved by technology

The side of the existing unloading valve device is generally installed and closed with 4 flat steel plates. Due to the main building frame of the steel structure of the mixing equipment and the aggregate hopper, the amount of deformation produced is not large when the aggregate is stored and put in. Similarly, the coaming installed on the side of the unloading valve device bears the alternating stress of tension and compression. After many times of operation, some coamings crack and even are severely cut off.

Since the aggregate sand and stone generally contain a certain amount of water, if the mixing equipment is operated in rainy days, the water content in the sand and stone will be greater. water will seep out from the side, causing water leakage in the discharge valve unit

On the other hand, there is a water distribution pipe on the top of the main machine cover, and several nozzles are arranged on the water distribution pipe. The water sprayed by the nozzles is scattered, and part of the water splashes onto the side plate of the discharge valve device. When there are cracks in the board or there is a gap in the coaming, the water will seep out from the side and flow directly to the main engine cover. Because the concrete aggregate is added with liquid additives and is corrosive, it will pollute the environment.
