Embodiment 1

[0037] like figure 1 As shown, this embodiment provides an automatic cleaning device for a belt sludge dryer. The dryer includes a box body 1, a mesh belt sludge conveyor 2 and a control system (not shown in the figure). The sludge conveyor 2 is installed inside the box 1, the sludge dryer is electrically connected to the control system, and the side wall of the box 1 is provided with a return air outlet 3; the dryer also includes an automatic cleaning machine. Ash device, the automatic dust removal device is electrically connected with the control system, the automatic dust removal device is located above the mesh belt sludge conveyor 2, and is located outside the air return port 3, and the box body 1 is divided into a negative pressure chamber and a positive pressure chamber; the automatic dust removal device includes a filter mechanism, a collection mechanism, a mechanical shaker 15 and an inductor, and the collection mechanism is located below the filter mechanism and loca...

Embodiment 2

[0061] like Figure 8 As shown, the working sequence and process of the automatic dust removal device and components in this embodiment are the same as those in Embodiment 1. The difference is that the duration of action of the mechanical shaker 15 in the control method of this embodiment can be manually set in the control system. , without the control system judging whether the tensile stress value measured by the strain gauge 12 reaches a certain lower threshold before stopping the mechanical shaker 15 .

Abstract

An automatic dust removal device for a belt sludge dryer and its control method. The dryer includes a box body, a mesh belt sludge conveyor and a control system. The side wall of the box body is provided with an air return port. The dryer It also includes an automatic dust removal device. The automatic dust removal device includes a filter mechanism, a collection mechanism, a mechanical shaker and an sensor. The collection mechanism is located below the filter mechanism and is located on the mesh belt sludge conveyor Above, the mechanical shaker is used to drive the filter mechanism to vibrate, and the sensor is used to start or stop the mechanical shaker. The invention monitors the change of the filter mechanism through the sensor, and the control system controls the start or stop of the mechanical vibrator, so that the dust in the filter mechanism is collected by the collection mechanism. The invention greatly reduces the maintenance times of the dust filter device in the drying box, lowers the operation and maintenance cost, and at the same time, the dust concentration in the drying box can be kept at a low level for a long time.

Description

technical field [0001] The invention relates to the field of sludge treatment in environmental protection products, and more specifically relates to an automatic ash cleaning device for a belt sludge dryer and a control method thereof. Background technique [0002] At present, most belt sludge dryers use hot air drying, and the hot air in the drying box is in direct contact with the sludge. When the dehydration reaches a certain level, the properties of the sludge change, the surface cracks and shrinks, and the material originally formed in strips breaks into granules. Coupled with the friction during the conveying process, part of the dry mud particles are further crushed and become slag or powder. With the circulation of the hot air, fine dust particles or powders are carried up and dispersed throughout the drying box, and even overflow outside the machine. When the dust concentration exceeds a certain limit, there is a risk of explosion, and when the dust enters the hea...
