Background
Wet garbage such as kitchen garbage and the like has high water content and high fluidity and is easy to leak, so that secondary pollution is caused by surface water and underground water pollution; moreover, a large amount of water in the wet garbage is not favorable for garbage transportation and is not favorable for garbage incineration treatment, so that the wet garbage needs to be dehydrated and dried.
The existing wet garbage squeezing machine adopts a screw thrust physical squeezing mode for dehydration, generally adopts a single-shaft single-line screw or a double-shaft single-line screw, and obtains a certain compression ratio by means of reducing, variable pitch and the like. However, the lead angle of the wire spiral is small, the friction force is large when the wire spiral pushes materials, and the forward thrust is small, so in order to further improve the dehydration effect of the wet garbage squeezing machine, a means of increasing the back pressure (namely the reverse pressure) is adopted. The back pressure is increased by means of matching the reverse push disc and the spring gland, and the pressure of the spring is regulated by means of nut, oil cylinder or air cylinder. This adjustment is required at shutdown and does not facilitate the adjustment of the spring pressure at any time. And because the acting force adjusted by the oil cylinder and the air cylinder is not on the axis of the extrusion screw, the pressure is inconvenient to be uniformly adjusted.
In addition, even though the conventional wet garbage squeezing machine increases the dehydration rate by increasing the back pressure, the moisture content of the basic residue is still high, and is usually about 60%.

As shown in fig. 1-6, the conventional wringing machine for dewatering wet garbage comprises a housing 1 provided with a feed inlet 11, a spiral wringing device 2 arranged in the housing 1, and a driving device 3 for driving the spiral wringing device 2 to rotate so as to push the wet garbage to move towards a discharge outlet. When the squeezing machine is used for dehydrating wet garbage, such as kitchen garbage, a user starts the driving device 3, and puts the wet garbage into the machine shell 1 from the feeding hole 11, the wet garbage entering the machine shell 1 rubs with the spiral squeezing device 2 under the rotation action of the spiral squeezing device 2 to generate heat so as to dehydrate the wet garbage for the first time, the wet garbage is pushed to the discharging hole at the same time, the wet garbage finally dehydrated for the first time flows out from the discharging hole, and the generated wastewater flows into the wastewater tank 5 arranged on the machine shell 1.
In order to prevent the wet garbage from scattering out when the wet garbage is added into the cabinet 1, a feed hopper is further installed at the feed port 11 of the cabinet 1. Wherein the drive means 3 comprise a motor. An output shaft of the motor is connected with the tail end of the spiral drying device 2 through a coupler so as to drive the spiral drying device 2 to rotate. In addition, the motor is preferably a reduction motor in order to reduce the rotation speed of the motor.
However, only the wet garbage is dehydrated once through the above manner, the moisture content of the wet garbage flowing out of the discharge port is still high, generally reaching about 60%, and in order to improve the dehydration rate, the embodiment provides a kitchen garbage wringing machine, which includes, in addition to the above components, a wringing device 4 for squeezing the wet garbage at the discharge port; this wringing device 4 is parallel with the axis of spiral wringing device 2 to the effort of the wet rubbish of discharge gate department, and the even adjustment of being convenient for like this improves extrusion efficiency to the effort of the wet rubbish of discharge gate department, and then realizes the secondary dehydration drying to exporting the residue from the discharge gate, improves the dehydration rate.
Preferably, the acting force of the squeezing device 4 on the wet garbage at the discharge port coincides with the central axis of the spiral squeezing device 2.
As shown in fig. 1-6, the screw wringing device 2 comprises a double-screw shaft 21 and a water filtering shell 22 which are rotationally connected with the driving device 3; the front end of the double-screw shaft 21 axially penetrates through the water filtering shell 2 to be connected with the squeezing device 4.
At present, a single-shaft single-line screw shaft or a double-shaft single-line screw shaft is generally adopted in the existing squeezing machine for dehydrating wet garbage, and a certain compression ratio is obtained by means of reducing, torque changing and the like so as to realize the pressure dehydration and conveying of the wet garbage. However, because the helix angle of the single-line screw shaft is smaller, the friction force is larger when pushing materials, and the forward thrust force is smaller, the double-line screw shaft is adopted to replace the single-line screw shaft in the prior art, the friction force is smaller when the double-line screw shaft is adopted to push wet garbage, and the conveying speed and the forward thrust force of the double-line screw shaft to the wet garbage are far greater than those of the single-line screw shaft, so that the treatment capacity of the wet garbage in unit time can be improved. In addition, because the resistance of the double-screw shaft is small, the same power can obtain higher rotating speed, so that the friction force between the double-screw shaft and materials is increased to generate higher temperature, the dehydration and drying of wet garbage are facilitated, and the dehydration effect is improved.
The front end of the double-line spiral shaft 21 axially penetrates through the water filtering shell 22 to be connected with the squeezing device 4, and the squeezing device 4 is used for squeezing out wet garbage at the material outlet 12, so that the squeezing device 4 can squeeze the wet garbage to a certain degree, namely, the wet garbage is dehydrated for the second time, and the dehydrating efficiency of the wet garbage is further improved.
As shown in fig. 7-10, the lead L of the twin-screw axis 21 is greater than the major diameter D of the screw, and the lead angle is 30 ° to 40 °. Preferably, the lead L of the twin-screw shaft 21 is twice the major diameter D of the screw, and the lead angle is 35 °. The lead and the lead angle of the twin-screw shaft 21 are limited to reduce the resistance of the twin-screw shaft to the maximum extent, so that higher rotating speed can be obtained under the condition of the same power, the friction force between the twin-screw shaft and materials is increased to generate higher temperature, the dehydration and drying of wet garbage are facilitated, and the dehydration effect is improved.
In order to make up for the lack of friction force when pushing wet garbage and to make the friction force and the forward thrust reach a certain balance, in this embodiment, a wear-resistant protrusion is further disposed on the surface of the helical blade of the double-line helical shaft 21, preferably, the wear-resistant protrusion is formed by overlaying a wear-resistant material on the surface of the helical blade, and the wear-resistant protrusion has a tearing and crushing effect on the wet garbage, so that the wet garbage does not need to be thrown in a broken bag and manually sorted.
Wherein the wear resistant material may be a metallic material such as stainless steel, iron, NM500 wear resistant steel, etc.
The "lead" in this embodiment refers to the "thread lead", and specifically the axial distance that any point on a thread moves along one thread revolution.
The "lead angle" in this embodiment is also referred to as the "lead angle" or "lead angle", and the angle of the tangent to the helix to a plane perpendicular to the axis of the thread is on the cylinder or cone of the medium diameter. In worm and gear transmission, the lead angle of the worm is the included angle between the tangent line of the spiral line on the indexing cylinder of the worm and the end surface of the worm.
As shown in fig. 11 to 13, the water filtering casing 22 includes a casing 221, and a plurality of stoppers 222 are detachably provided on an inner wall of the casing 221. The blocking part 222 has a certain blocking effect on the wet garbage pushed by the double-line spiral shaft, so that the wet garbage forms complex motion states such as tearing, crushing, kneading, extruding, wringing and the like in the shell 221, the purpose of powerful dehydration is achieved, and the dehydration rate is further improved.
The blocking portions 222 are elongated, and the blocking portions 222 are axially and detachably disposed on the inner wall of the housing 221 at intervals. Preferably, the blocking portion 222 is a wear-resistant blocking strip uniformly and axially detachably distributed on the inner wall of the shell 221, and the material thereof is preferably NM500 wear-resistant steel. The blocking part 222 and the shell 221 are detachably mounted, so that the installation and maintenance are convenient, and the service life of the equipment is prolonged.
In a specific embodiment, the inner sidewall of the casing 221 is provided with a plurality of grooves at intervals in the axial direction, the blocking portion 222 is axially inserted and clamped in the grooves, and the blocking portion 222 is radially and threadedly mounted on the casing 221 by using screws. To ensure the blocking effect, the blocking portion 222 protrudes from the inner surface of the housing 221.
As shown in fig. 1 to 6, the wringing device 4 includes a reverse pusher 41 and a reverse wringing member 42;
the reverse wringing component 42 is arranged at the front end of the double-line screw shaft 21, the reverse pushing component 41 is connected with the water filtering shell 22, and a gap is reserved between the reverse pushing component and the end surface of the water filtering shell 22, and the gap is a discharge hole; the reverse wringing component 42 also interfaces with the reverse pusher 41 for applying a force to the reverse pusher 41 to maintain, expand or reduce the size of the spout.
Because the discharge gate is formed by the preceding terminal surface of straining water shell 22 and the gap between the backstepping piece 41, so the discharge gate is less than straining water shell 22 far away, and the wet rubbish of so following the discharge gate output must be extruded, has realized the secondary dehydration to wet rubbish like this, improves the dehydration effect.
The size of the discharge port can be adjusted through the reverse wringing component 42 according to actual needs. The method specifically comprises the following steps: if the size of the discharge port needs to be maintained, the urging force of the reverse wringing member 42 to the reverse pusher 41 may be kept constant, and the moisture content of the residue extruded from the discharge port may be kept constant. If the size of the discharge port needs to be increased, the force applied to the reaction member 41 by the reverse wringing member 42 is reduced, and the moisture content of the residue extruded from the discharge port is increased. If the size of the discharge port needs to be reduced, the force applied by the reverse wringing component 42 to the reverse thrust piece 41 is increased, and the moisture content of the residue extruded from the discharge port is reduced.
As shown in fig. 1, the thrust reverser 41 has a disc-shaped structure, and the thrust reverser 41 is sleeved on the twin-screw shaft 21 and rotates along with the twin-screw shaft 21. Since the extruded wet garbage has a high temperature, the reverse thrust member 41 rotating with the twin screw shaft 21 is provided with a scattering portion; the scattering part is arranged in the discharge port and used for scattering the extruded wet garbage, so that the further evaporation of water is facilitated, and the dehydration effect is improved.
Preferably, the reverse pushing piece is welded with the alloy blade in an inlaid mode, the function of scattering extruded wet garbage is achieved, further evaporation of water is facilitated, and the dehydration effect is improved.
As shown in fig. 5 and 6, the reverse wringing component 42 includes a resilient component 421 and a thrust component 422; one end of the elastic component 421 is connected with the reverse pushing component 41, and the other end is connected with the reverse pushing component 422; the reaction assembly 422 applies force to the reaction member 41 by pressing the elastic assembly 421 to maintain, expand or reduce the size of the discharge hole. Wherein the resilient member 421 acts as a buffer to allow the discharge of hard, uncrushable material. The water content of the residue extruded from the discharge port is adjusted by adjusting the size of the discharge port.
The elastic component 421 comprises an elastic body 4211, and an elastic piece gland 4212 arranged at the end part of the elastic body 4211; one end of the elastic body 4211 is connected with the thrust reverser 41, and the other end is connected with the thrust reverser assembly 422 through an elastic body gland 4212. Among them, the elastic member 4211 is preferably a spring, and the spring is sleeved on the twin-screw shaft 21.
