Pre-dissolving device for flocculating powder

Abstract

The invention discloses a flocculated powder initial dissolving device, which comprises an upper cavity body, a lower cavity body, a medicament catching tray, an upper water pipe spray head and a lower water pipe spray head. The upper cavity body and the lower cavity body are connected into a whole and communicated with each other; an openable cover is arranged at the top part of the upper cavitybody; a blanking port is formed in the middle position of the cover; the edges of the blanking port bend inwards; a ring that is movably inserted into the upper cavity body is arranged below the cover; the medicament catching tray is mounted on the ring and positioned below the blanking port; the upper water pipe spray head is mounted in the upper cavity body and at the same time aligned with themedicament catching tray; the lower water pipe spray head is mounted in the lower cavity body and aligned with the top wall of the lower cavity body; and a lower water port is arranged at the bottom of the lower cavity body. The device prolongs the time and increases the times of contact between the flocculated powder and water, so that the dissolution of the flocculated powder is facilitated, andthe dissolution of the flocculated powder in the initial dissolving device is more complete. Compared with the original design, the parts of the device are easier to produce, save material, simplifythe processing procedure and shorten the time for manufacturing the medicament feeding mechanism.

Description

Technical field: [0001] The invention relates to a flocculation powder dosing system in the sewage treatment process, which belongs to the field of environmental protection equipment, in particular to an initial dissolution device in the flocculation powder dosing system. Background technique: [0002] The flocculation powder dosing system is to add flocculation powder dilution to the muddy water in the water treatment process to achieve the effect of muddy water separation. The dilution process is: the screw at the bottom of the flocculation powder box discharges the flocculation powder and falls into the initial dissolution device of the flocculation powder for initial dissolution, and then is further stirred and dissolved by the liquid medicine tank and then added to the muddy water to be treated. [0003] Among them, the flocculant powder initial dissolving device is a device designed to dissolve as much flocculant powder as possible. Because the flocculant powder has ch...

Problems solved by technology

[0004] The original flocculation powder initial dissolution device such as figure 1 As shown, it mainly includes an upper body 2 and a lower body 6. After the two are assembled, the shell of the flocculation powder primary dissolution device is formed. The upper and lower bodies are sealed by a sealing ring 7 and fixedly connected by nuts 3, bolts 4 and gaskets 5. The upper body The upper cover 1 is installed on the top of the body 2, and the screw rod at the bottom of the flocculation powder box passes through the upper body 2, and the flocculation powder is added into the initial dissolution device through the screw rod, and a flushing nozzle is installed horizontally under the screw rod to rinse and dissolve the falling flocculation powder , the number and time of contact between the flocculation powder and water in this device are less, a large amount of space in the device is not used, and the processing of parts is not only troublesome but also wastes more materials
