Specific embodiment

With reference to the accompanying drawings, the function that the structure of this system is described in detail and is realized.

A kind of sludge treatment equipment comprising frozen part, multiple moisture transducers 21, control unit,

The frozen part is made of household freezer 11, cooling component 12 and push rod case 13, in which:

Household freezer 11 includes:

Cabinet 111 is fixed on ground by the bracket of lower section, and the side of cabinet 111 is provided with sludge inlet 115, case The upper surface of body 111 is provided with multiple push-rod holes 116；The box outer surface of the underface of each push-rod hole 116 is provided with one A sludge outlet 117, each sludge outlet 117 is mounted on electric gate valve, for controlling the opening and closing of sludge outlet；Sludge inlet 115 left side is provided with refluxing opening 118, is equipped with electric gate valve on refluxing opening 118, for controlling the opening and closing of refluxing opening, flows back It is connected between mouth and sludge inlet with pipeline；

First partition 112 is placed horizontally in cabinet 111；

Second partition 113 is longitudinally placed in cabinet 111, and cabinet 111 is divided into sludge inlet with first partition 112 Section freezes just section, middle section, four regions of latter end；

Cooling component 12 includes cooling tube 121 and refrigeration machine, and multiple cooling tubes 121 are mounted on the at equal intervals from top to bottom Two partitions, 113 two sides, managing interior circulation has refrigerant；

Push rod case 13 is arranged above household freezer 11, with multiple push rods 131, sets right above each push-rod hole 115 There is a push rod 131, push rod 131 releases the sludge that freezing finishes from corresponding sludge outlet 117 by push-rod hole 116；

After sludge enters sludge inlet 115, flowed by the first path of default, the first path refer to sludge into Enter sludge inlet section, by subsequent sludge promotion along first partition 112 rise to top communication port, into freeze just section, The sludge completed is freezed to be released by the warp of push rod 131 positioned at the sludge outlet 117 for freezing just section,

Multiple moisture transducers 21, are divided into, and lower two rows are set in qually spaced in the inner wall of the cabinet 111 of household freezer 11 On, the water content for sludge in real-time measurement household freezer；

When sludge is by being located at the communication port above partition 112, into subsequent region, it is aqueous that moisture transducer measures sludge The fall of amount is less than system standard value, and when refrigerator operation power is not up to rated power, and control unit controls refrigeration machine Reach rated power, increases the conveying capacity of refrigerant in cooling tube, refrigerant temperature decline, to accelerate the freezing of sludge；

When refrigerator operation power has reached rated power, control unit makes sludge by freezing longer second path in path It is flowed, to increase cooling time of the sludge in household freezer, second path refers to that sludge passes through on second partition 113 The communication port of side enters freezing middle section, then enters freezing latter end by communication port, finally, the sludge that freezing is completed is passed through by push rod 131 It is released positioned at freezing latter end bottom sludge outlet 117.

If the sludge moisture content that moisture transducer 21 measures is still higher than system standard value after sludge enters freezing latter end, The electric gate valve that control unit controls refluxing opening 118 is opened, and is flowed out sludge from refluxing opening 118, is back to sludge by pipeline At entrance 115, reenters in household freezer and freezed.

One skilled in the art would recognize that without departing substantially from the spirit and scope of the invention as generally describing, Various variations and/or modification can be carried out to invention shown in each specific embodiment.Therefore, in terms of all For, embodiment here is considered as illustrative and and non-limiting.Equally, the present invention includes any feature Combination, the combination of any feature especially in Patent right requirement, even if the combination of this feature or feature is not in patent It is explicitely stated in claim or each embodiment here.
