Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 4, a kitchen waste treatment apparatus includes an upper housing 1, a lower housing 2, a crushing chamber 3, a sewage inlet 4, a sealing cover 12, a crushing cutter group, and a motor.

Lower casing 2 and last casing 1 connect into an organic whole and accomodate the chamber, smash chamber 3 and motor and install and accomodate the intracavity, and motor seal installation smashes 3 bottoms in chamber. The sewage inlet 4 is arranged at the opening at the top of the upper shell 1 and is hermetically arranged with the top of the crushing cavity 3. The sewage inlet 4 is used as a sewage inlet and is also used as a water tank connecting and fixing piece to be arranged below a water outlet of the water tank. The crushing cutter set is arranged in the crushing cavity 3, and the main shaft of the motor is connected with the crushing cutter set. The crushing cavity 3 is provided with a water inlet 32, the water inlet 32 is connected with a water tap, the sealing cover 12 is provided with a sewage outlet 54, and the sewage outlet 54 is connected with a sewer. The upper shell 1 and the lower shell 2 are both provided with avoidance holes for water pipes to pass through.

The crushing cutter set comprises a worm driving shaft 7, a worm wheel rotating shaft 8 and a worm wheel 13, the worm driving shaft 7 is vertically connected with a main shaft of a motor, and the worm wheel rotating shafts 8 are horizontally installed on two sides of the worm driving shaft 7 in an opposite mode. The worm wheel rotation shafts 8 are rotatably installed, and worm wheels 13 are respectively installed on the worm wheel rotation shafts 8 and engaged with the worm drive shaft 7. The worm wheel rotating shaft 8 is provided with a plurality of cutter teeth 81, the cutter teeth 81 are arranged in a spiral line form, and the cutter teeth 81 on the two worm wheel rotating shafts 8 are overlapped in a staggered manner. The kitchen garbage entering the crushing cavity 3 from the sewage inlet 4 firstly falls onto the rotating worm wheel rotating shaft 8, then is cut by the cutter teeth 81 to form small-volume fragments, and then continuously falls below for secondary crushing. Therefore, the high-speed blade is prevented from directly cutting hard or large objects to aggravate abrasion, and meanwhile, the noise generated when the high-speed blade is crushed is also reduced.

In order to realize the secondary crushing, the crushing cutter group also comprises a crushing cutter head 6, a plurality of blades are installed at the edge of the crushing cutter head 6, and a plurality of through holes are formed in the disk surface and used for blanking. The shredder disk 6 is mounted on a worm drive shaft 7 and is located below a worm gear rotating shaft 8. The rotation speed ratio of the worm driving shaft 7 to the worm gear rotating shaft 8 is 2-3: 1, so that the rotation speed of the crushing cutter disc 6 is larger than that of the worm gear rotating shaft 8, and crushing of small-volume objects is achieved. Therefore, the pressure of the crushing cutter head is greatly reduced, and the service life is greatly prolonged.

In order to improve the secondary crushing effect, a plurality of fixed cutter teeth 31 which are distributed circumferentially are arranged on the inner wall of the crushing cavity 3 corresponding to the crushing cutter head 6. The blades generate cutting force with the fixed cutter teeth 31 when rotating, thereby improving the crushing effect.

Because the kitchen garbage contains a large amount of grease, grease lumps are not easy to clean when the temperature is low. Meanwhile, the normal operation of the motor is affected by heat generated during the operation of the motor. Therefore, the motor is improved as follows:

the motor includes motor casing 5, and motor casing 5 is provided with 8 circumference evenly distributed and along the cooling water course 51, first mouth of a river 52 and the second mouth of a river 55 of axis extension. The first water gap 52 is connected at the one end that the cooling water channel 51 is close to sealed lid 12, and the second water gap 55 is connected at the other end that sealed lid 12 was kept away from to the cooling water channel 51, and one of them first water gap 52 is as external water source entry, and another first water gap 52 is as the return water export of water inlet 32, and remaining first water gap 52 is two liang of connections through first connecting pipe 3 respectively, and all second water gaps 55 are two liang of connections through second connecting pipe 9 respectively, and all cooling water channels 51 all end to end form a complete water route like this. The water flowing out from the water tap firstly enters the cooling water channel 51 to cool the motor casing, and then the water is heated by the motor casing and then returns to the crushing cavity 3 to flush the crushed garbage into a sewer. Because the water temperature is higher, the grease removing capacity is greatly improved, and the oil stain residue is avoided.

In order to better cooperate with heat dissipation, the heat dissipation device also comprises a water inlet pipe 10, and an electromagnetic valve 11 is installed on the water inlet pipe 10. The water inlet pipe 10 is connected with the water inlet 32, the water inlet pipe 10 is provided with a water outlet 101 positioned on the water inlet side of the electromagnetic valve 11 and a water return port 102 positioned on the water outlet side of the electromagnetic valve 11, the water outlet 101 is connected with the first water inlet 52 serving as an inlet of an external water source through a water pipe, and the water return port 102 is connected with the first water inlet 52 serving as a water return outlet of the water inlet 32 through a water pipe. When the water-saving type crushing device is used normally, the electromagnetic valve is in an open state, and water flowing out of the water faucet directly enters the crushing cavity 3 through the water inlet pipe 10 to be washed. When the motor needs to be cooled, the electromagnetic valve is closed, at the moment, water flows out of the water outlet 101 and flows into the cooling water channel 51 for cooling, and then enters the crushing cavity 3 through the water return port 102.

The return port 102 is disposed downward due to a possibility of being restricted by a space on site at the time of installation, and a check valve is further connected to a pipe between the return port 102 and the first water port 52 as a return outlet of the water inlet 32 in order to prevent the garbage in the pulverization chamber 3 from flowing backward into the cooling water passage 51.
