Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sludge combustion treatment equipment, specifically to a sludge material briquetting forming pretreatment device for sludge blending combustion treatment. BACKGROUND

[0002] In the sludge treatment process, sludge incineration is a key link. In this process, the dewatered sludge is heated and dried by the combustion boiler, and the organic matter in the sludge is oxidized by high temperature, and finally it is converted into ash, so as to achieve the purpose of sludge reduction, stabilization and harmlessness. In order to improve the efficiency of sludge incineration, usually before the sludge is put into the combustion boiler, pretreatment will be carried out, that is, the sludge is briquetted. Compared with the sludge in fluid state, the briquetted sludge is more convenient to put into the combustion boiler, which significantly improves the convenience of feeding.

[0003] The feeding pretreatment device for improving the efficiency of sludge combustion boiler in the patent of Chinese patent publication No. CN218409946U, before the sludge is injected into the briquetting box, the cylindrical rod at the bottom of the sealing plate is inserted into the briquetting box. After the briquetting of sludge, a large number of cylindrical rods installed at the bottom of the sealing plate can form a porous structure for the sludge block, so that the high temperature in the combustion boiler can quickly enter the inside of the sludge block during the incineration process, which shortens the time required for incineration and effectively improves the efficiency of sludge incineration.

[0004] However, this device also faces some problems in actual use. First of all, when the push rod pushes the push plate to push the sludge to the briquetting interval, the sludge is easy to adhere to the inner wall of the briquetting box, causing pollution. Secondly, if the amount of sludge in the feeding hopper is not properly controlled, too much sludge may overflow and accumulate on the back of the push plate, affecting the normal movement and use of the push plate. In addition, due to the different water content of different sludge and the different amount of sludge each time, it may also lead to inconsistent specifications of the final treated mud block, thereby affecting the incineration effect and efficiency.
