Organic castoff compost spiral mixer
The utility model relates to compost batch mixer field, particularly relates to organic castoff compost spiral mixer.
In recent years, along with the fast development of China's economy and the continuous reinforcement of Environmental pollution management, drive the raising gradually of wastewater treatment in China efficiency, meanwhile, sewage disposal process produces a large amount of excess sludges to be had pending.Containing abundant organic matter, nitrogen, phosphorus and some other nutriment in excess sludge of municipal sewage plant, there is considerable fertilizer efficiency composition.The process of excess sludge aerobic compost is one of modal mode in Treatment of Sludge.
Conventional composting material washiness, impurity is many, granularity is unequal, needs to add the moisture, C/N etc. that conditioner regulates raw material.Raw material is mixed by batch mixer with conditioner, makes the composting conditions that compound reaches applicable.Conventional batch mixer has horizontal and vertical two kinds, in existing vertical mixer, owing to being subject to the impact of weight of material in vane type batch mixer process, it needs very large driving force being uniformly mixed stirring vane in process, therefore have high requirements to the power of drive motors, production power consumption is high.And the crosswise pushing material of traditional Horizontal type mixer, mixing is even not, affects compost effect.
Utility model content
Technical problem to be solved in the utility model is to provide organic castoff compost batch mixer, to improve compounding effect, reduce energy consumption, to reduce and produce and operating cost.
The utility model solves the problems of the technologies described above with following technical scheme:
The utility model organic castoff compost spiral mixer, comprise housing, in housing, shaft is installed, shaft is fixed with helical blade, shaft drives it to rotate by the transmission device being arranged on hull outside, the top of described housing is provided with conditioner feeding mouth, organic waste feeding mouth and service port side by side, and bottom is provided with discharging opening; Shaft is laterally arrangement, and shaft is provided with circulator, and circulator is positioned at the rear side of two feeding mouths; Conditioner feeding mouth and organic waste feeding mouth are positioned at the side of housing, and discharging opening is positioned at the opposite side of housing.
Described circulator is vertical eccentric plate, is tightly placed on shaft, and the distance of its one end and housing is greater than the distance of the other end and housing.
Described circulator is 2-4, is intervally arranged, and spacing is 800 ~ 1000mm, and first circulator and feeding mouth minimum range are 800mm.
Described conditioner feeding mouth, organic waste feeding mouth and service port all in inverted trapezoidal, and are respectively equipped with quick detachable end cap.
The utility model has that structure is simple, power consumption is little, volume is little, batch mixing speed fast, mud bonding less with advantage easy to maintenance.Owing to having additional circulator, material can be made to form circulation stirring, make mixing of materials evenly, and the end cap that conditioner feeding mouth, organic waste feeding mouth and service port all adopt Quick-disassembling device to be connected, can open end casing fast, clear up easy to maintenance.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, the utility model organic castoff compost batch mixer comprises: housing 1, shaft 8, conditioner feeding mouth 3, organic waste feeding mouth 4, circulator 7, service port 5, discharging opening 6, transmission device 9 and end cap 10.Conditioner feeding mouth 3, organic waste feeding mouth 4, service port 5 are disposed side by side on the top of housing 10, discharging opening 6 is arranged on the bottom of housing 10, conditioner feeding mouth 3 and organic waste feeding mouth 4 are positioned at the side of housing, and discharging opening 6 is positioned at the opposite side of housing.The shaft 8 of laterally arrangement is installed in housing 10, shaft 8 drives it to rotate by the transmission device 9 be arranged on outside housing 10, transmission device 9 comprises motor, reductor, transmission device 9 and shaft 8 are arranged on housing pivotly, and shaft 8 is formed to drive with transmission device 9 by shaft coupling transmission or Chain conveyer and is connected.Circulator 7 and helical blade 2 are arranged on shaft 8, and circulator 7 is positioned at the rear side of organic waste feeding mouth 4.
Circulator 7 described in the utility model is vertical eccentric plate, be tightly placed on shaft 8, the distance of its one end and housing is greater than the distance of the other end and housing, as shown in Figure 2, circulator 7 top exceeds shaft 8 about 100mm, the gap of its bottom and housing bottom is about 20mm, is 20 ~ 50mm with the gap of housing 1 both sides.Circulator can arrange 2-4, is intervally arranged, and spacing is 800 ~ 1000mm, and the minimum range of first circulator and organic waste feeding mouth 4 is 800mm.By arranging circulator, can make material formed circulation stirring, make mixing of materials evenly.
Conditioner feeding mouth described in the utility model, organic waste feeding mouth and service port all in inverted trapezoidal, and are respectively equipped with quick detachable end cap 10, and end cap 10 adopts Quick-disassembling device to connect, and can open end casing fast, clear up easy to maintenance.
The course of work of the utility model organic castoff compost batch mixer is as follows:
Conditioner (such as wood chip) is entered batch mixer from conditioner feeding mouth 3, organic waste (such as Sewage Plant dewatered sludge) is entered batch mixer from organic waste feeding mouth 4, shaft 8 drives it to rotate by transmission device 9, helical blade 2 also rotates thereupon, and conditioner and organic waste is carried out being uniformly mixed and moving right.
When compound moves right in process and encounters circulator 7, circulator 7 stops that compound continues to move right, compound just forms circulation stirring, then piling height is crossed circulator 7 and is continued to move right (as shown in Figure 3) after exceeding circulator 7, when compound moves to second circulator, same formation circulation stirring, make material particular diameter evenly, last compound is got rid of to composting arrangement from discharging opening 6.
The organic waste of the utility model process comprises Sewage Plant dewatered sludge, sewage sludge, paper mill sludge, fowl and animal excrement, septic tank ight soil etc.
The conditioner that the utility model adopts comprises stalk, wood chip, rice husk, straw, leaf, boll hull etc.
