Domestic refuse dewatering machine
Technical field
The utility model relates to a kind of refuse disposal installation, particularly relates to a kind of house refuse dewater unit.
Background technology
The method that domestic waste is handled generally has four kinds both at home and abroad, be landfill, compost, pyrolysis and burning, wherein burning disposal can reach the resultant effect of innoxious, minimizing, resource, effectively prevents the propagation of germ, helps the comprehensive utilization of heat energy.But because house refuse moisture height, caloric value is low, and the single rubbish difficulty of directly burning is big, and especially the content of combustible component is less relatively in the house refuse of small and medium-sized cities, and the difficulty of directly burning is bigger; In order to make rubbish smooth combustion, it is combustion-supporting often to need to add some auxiliary fuels, has so just strengthened operating cost.Show that as calculated to the house refuse of small and medium-sized cities, moisture content reduces to 40% by 53%, the caloric value of rubbish is brought up to 6200KJ/kg by 4300KJ/kg, theoretical temperature combustion can improve nearly 250 ℃, and this is to smooth combustion, and the degree fully that improves incineration firing is very favorable.Therefore need seek a kind ofly can make water content in the rubbish can reduce to high effective dehydration device below 40%.
The utility model content
The purpose of this utility model is to provide a kind of domestic refuse dewatering machine, and this dewaterer is simple in structure, and the dewatering efficiency height can make in the rubbish water content reduce to below 40%.
The utility model is achieved through the following technical solutions for solving the problems of the technologies described above, described domestic refuse dewatering machine, comprise hopper, hopper, pushing block, push rod, above-mentioned pushing block places in the hopper, and links with push rod, and above-mentioned hopper is divided into feed zone, binder section, discharging section.
Above-mentioned hopper is the flat cylindrical shell.
The binder section outer wall of above-mentioned hopper is equipped with reinforcement.
Be equipped with osculum on the binder section outer wall of above-mentioned hopper.
The feed zone of above-mentioned hopper, discharging section are uiform section, and above-mentioned binder section cross section dwindles gradually.
Match with the feed zone cross section in above-mentioned pushing block cross section.
The utility model compared with prior art has following advantage:
This domestic refuse dewatering machine can make rubbish before burning, the preliminary treatment of dewatering earlier, can get rid of the part moisture in the rubbish on the one hand, solid matter on the other hand can broken rubbish, so not only can improve the caloric value of rubbish, and can quicken the evaporation of residual moisture, help the smooth combustion of rubbish, simple in structure, the dewatering efficiency height.
Description of drawings
Fig. 1 is the structural representation of the utility model domestic refuse dewatering machine;
Fig. 2 is the I partial enlarged drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing domestic refuse dewatering machine embodiment of the present utility model is described further.
As shown in Figure 1 and Figure 2, described domestic refuse dewatering machine, comprise hopper 1, hopper 2, pushing block 3, push rod 4, above-mentioned hopper is divided into feed zone 11, binder section 12, discharging section 13, above-mentioned pushing block 3 places in the hopper 1, and link with push rod 4, above-mentioned hopper 1 is the flat cylindrical shell, binder section 12 outer walls of above-mentioned hopper 1 are equipped with reinforcement 121, be equipped with osculum 122 on binder section 12 outer walls of above-mentioned hopper 1, the feed zone 11 of above-mentioned hopper 1, discharging section 13 are uiform section, and above-mentioned binder section 12 cross sections dwindle gradually, match with feed zone 11 cross sections in above-mentioned pushing block 4 cross sections.
During work, rubbish is delivered in the hopper 2 by preposition transporting equipment, enters the feed zone 11 of hopper 1, under the promotion of push rod 4, make pushing block 3 make front-rear reciprocation movement, the rubbish that will drop in the hopper 1 when pushing block 3 travels forward is passed forward, in the process that rubbish moves forward, owing to be subjected to the effect of frictional force, the cross section dwindles gradually in addition, and the rubbish volume constantly reduces, and makes it to be squeezed, part moisture overflows from the osculum 122 on hopper 1 outer wall, and rubbish is from discharging section 13 dischargings of hopper 1.
