Embodiment Construction

[0021] The following is further described in detail through specific implementation methods:

[0022] The reference signs in the drawings of the description include: furnace body 1, sealing plate 2, closed box 3, high temperature level gauge 4, sand inlet pipe 5, sand outlet pipe 6, air outlet 7, partition plate 8, air chamber 9, A sand outlet chamber 10, a connecting piece 11, a cover body 12, a connecting pipe 13, and an air duct 14.

[0023] The embodiment is basically as attached figure 1 Shown: a roasting sand inlet and outlet device, including a furnace body 1 and an inlet and outlet sand structure. In this embodiment, the body of furnace 1 is a horizontal roasting furnace, and a sealing plate 2 is arranged in the lateral direction of the body of furnace 1. The sealing plate 2 separates the body of furnace 1 into two parts, that is, the body of furnace 1 is divided into an upper roasting chamber and a baking chamber by the sealing plate 2. The lower roasting chamber is...

Abstract

The invention belongs to the technical field of casting material treatment equipment and particularly discloses an incoming and outgoing sand roasting device which comprises a furnace body and is characterized by further comprising a sand inlet and outlet structure; the sand inlet and outlet structure comprises a sealed tank, a sand level control portion and a discharge portion and is arranged onthe side wall of the furnace body; the upper part of the sealed tank is provided with a sand inlet; the lower part of the sealed tank is provided with a sand outlet; the sealed tank is communicated with the furnace body through the sand inlet; the sand outlet is communicated with the discharge portion; and the sand level control portion can control discharge of the discharge portion. The device can realize sealing and automatic sand incoming and outgoing while sands go in and out.

Description

technical field [0001] The invention belongs to the technical field of mold material processing equipment, and in particular relates to a waste sand roasting system. Background technique [0002] The roasting furnace is the main equipment of the thermal regeneration technology of foundry waste sand. By roasting the waste sand at high temperature, the coating layer on the surface of the waste sand will fall off, and the regeneration and reuse of the waste sand will be realized. [0003] At present, the commonly used roasting furnace is a vertical two-layer roasting furnace. The upper part of the furnace body is connected with a feed pipe, and the inside of the furnace body is provided with a sealing plate. The bottom is connected with a discharge pipe and communicated with a main pipe, and a burner is arranged in the main pipe. The specific process of the roasting furnace is as follows: add waste sand to the upper roasting chamber through the feed pipe, the waste sand flows ...
