Leak-proof totally-closed discharging device

Abstract

The invention discloses a leak-proof totally-closed discharging device, belongs to the field of agricultural and animal husbandry equipment accessories, and aims to provide a leak-proof totally-closeddischarging device for reducing dust leakage generated by fine materials or blanking materials thereof, thereby improving environmental safety of a factory. The leak-proof totally-closed dischargingdevice comprises an outer casing, wherein the bottom of the outer casing is provided with a discharge opening; a storage plate is disposed on the inner side wall of the outer casing along the circumferential direction thereof; a lower side of the storage plate is abutted against a discharge gate plate; a storage bin with an opening on the upper end is formed between the storage plate and the discharge gate plate; a driving mechanism is mounted on the outer casing; the discharge gate plate is driven by the driving mechanism to control the storage and discharge of the storage bin. The leak-prooftotally-closed discharging device is suitable for discharging agricultural and livestock feed.

Description

technical field [0001] The invention relates to an accessory of agricultural and animal husbandry equipment, in particular to a leak-proof fully enclosed discharge device. Background technique [0002] The gate valve is the main equipment for the flow control of powder, grain material and small particle material. It is widely used in metallurgy, mining, building materials, grain, chemical industry and other industries. At present, the domestic pneumatic gate valve is mainly composed of cylinder, valve body, It is composed of gate plate and two-position five-way electromagnetic reversing valve. When applied to feed leakage in agriculture and animal husbandry, the ram will first seal the outlet of the silo, and then open the ram when the internal material has accumulated to a certain amount to allow material leakage. [0003] The Chinese patent with the notification number CN202203428U discloses a program-controlled pneumatic gate valve, which includes a housing and a valve p...

AI Technical Summary

Problems solved by technology

However, because the valve plate is often pulled and pulled, the degree of sealing between it and the shell will be reduced due to long-term service in the working state, and when the material falls into the silo for storage, a flowing airflow will be generated inside it, which is easy Make the powdered material leak and generate dust, especially when the entire pneumatic gate valve is installed at a high position, the leaked material will directly fall on the person

And the dust permeates the workshop for a long time. When the concentration reaches a certain level, it will explode when it encounters an open flame, which poses a great safety hazard.
