Water jacket cooling water system for falling tank and feeding platform of garbage incinerator

Abstract

The invention relates to the technical field of garbage incinerators, and aims to provide a water jacket cooling water system for a falling tank and a feeding platform of a garbage incinerator. The water jacket cooling water system is characterized in that the cooling effect is good, and maintenance is convenient. According to the technical scheme, the water jacket cooling water system for the falling tank and the feeding platform of the garbage incinerator comprises the falling tank, the feeding platform and a circulating mechanism, wherein the falling tank and the feeding platform are arranged in the up-down direction, and the circulating mechanism is used for supplying water to the falling tank and the feeding platform; the system is characterized in that the falling tank comprises twosymmetrically-arranged upper water jacket wall plates, the upper water jacket wall plates are both internally provided with a plurality of horizontally-arranged upper waterflow channels so that cooling water can flow along the upper waterflow channels, and the upper waterflow channels are internally provided with a plurality of upper water boxes which are arranged in the horizontal direction and communicate with one another; and the upper water box at the end of each upper waterflow channel is provided with an upper water outlet, or provided with an upper water inlet, or vertically communicates with the upper water box at end of another upper waterflow channel located above or below the upper waterflow channel.

Description

technical field [0001] The invention relates to the technical field of garbage incinerators, in particular to a water jacket cooling water system for a blanking chute and a feeding platform of a garbage incinerator. Background technique [0002] In the garbage incinerator, the grab grabs the garbage out of the garbage pit, then puts it into the falling chute and falls on the feeding platform, and then enters the incinerator for preheating, drying, burning until it is burned out. The blanking chute is the entrance for the waste to enter the incinerator. The rationality of its design directly determines whether the incinerator operates normally and stably. The feeding platform is connected to the blanking chute and the incinerator, which also plays a very critical role. [0003] The lower part of the blanking chute and the upper part of the feeding platform usually have two forms, one adopts the form of water jacket, and the other adopts the form of heat insulation. The water...

Problems solved by technology

[0004] Chinese patent ZL201010118515.3 discloses a continuous garbage feeding device capable of sealing flue gas and anti-clogging. The lower part of the feeding trough provided is in the form of a water jacket. Feeding platform, the upper part of the feeding platform is in the form of a water jacket, both of which adopt an open structure, although the structure is relatively simple, but there is a problem that the bottom is easy to scale

If the cooling water system with a closed structure is used instead, it is usually necessary to install a temperature sensor and a solenoid valve in the return water pipeline. When the return water temperature exceeds 80°C, an alarm will be issued and the solenoid valve will be opened to enter water, which can avoid scaling at the bottom of the water jacket. , so the structure is relatively complex, and the existing water jacket structure is difficult to apply to the cooling water system of the closed structure
