Description

The present invention dehydrates and dries the food waste quickly and easily regardless of the capacity of the food waste, effectively removes malodors generated from the food waste, and can be used more reliably and stably. The present invention relates to a waste disposal apparatus.

As the city develops and expands, there are fewer places to landfill, and the amount of waste to be landfilled or treated is faster, because the speed at which waste is released is faster than the time it takes to process itself. It is increasing.

In particular, in the case of food waste, there is a problem that the food waste contains a large amount of water and the bulk and weight of the waste is large, thereby increasing the processing cost of food waste.

Therefore, recently, a food waste treatment apparatus for dehydrating and drying food waste has been developed. However, since this food waste treatment device performs dehydration by rotating the inner cylinder at the time of dehydration, a lot of energy is required at the time of treatment of food waste such as for canteens where the capacity of food is large. It cannot be processed.

Moreover, since the conventional food / beverage treatment apparatus does not have a means for separately processing polluting gas and bad odor during food / beverage processing, there is also a problem that bad odor is generated during food / beverage waste processing.

Furthermore, since the conventional food waste processing apparatus has a structure that rotates a long inner cylinder, a large amount of rotational noise is generated when the inner cylinder rotates, and the accumulated food waste is accumulated without change in the position of the food waste stored inside the inner cylinder. Therefore, dehydration and drying cannot be performed uniformly. Accordingly, there is a problem that it takes a lot of time.

In particular, the conventional food waste treatment apparatus winds up an expensive heater wire around the entire outer peripheral surface of the inner cylinder, and the inner cylinder rotates, so that power can be supplied to the heater wire wound around the outer peripheral surface of the inner cylinder. There is also a problem that it is difficult to generate an error even when power is supplied.

Therefore, the object of the present invention devised to solve the above-described problems is to quickly and easily dehydrate and dry food waste, regardless of the capacity of food waste, and to effectively prevent malodors generated from food waste. It is an object to provide a food waste treatment apparatus that can be removed more easily and can be used more reliably and stably.

That is, the inner cylinder 6 is formed in a hopper shape in which the upper diameter is wider than the lower diameter and has the inner surface inclined portion 50. Therefore, although food and beverage waste concentrates on the lower part of the inner cylinder 6 by its own weight, since the shape of the inner cylinder 6 is a hopper shape, the concentration degree becomes larger.

The first heater wire 58 is wound along the outer peripheral surface of the inner cylinder 6 so as to dry the food waste stored in the inner cylinder 6 by applying heat. The first heater wire 58 is a resistance wire using general resistance heat generation, and the resistance invention by the resistance wire can be implemented by the conventional technique, and thus detailed description thereof is omitted. The food waste contained in the inner cylinder 6 is dried by the first heater wire 58.

The drive chamber 20 is provided with an agitation drive motor 32 that provides a drive force for rotating food and drink contained in the inner cylinder 6. The shaft of the agitation drive motor 32 is installed below the case 4, and a speed reducer 34 is mounted on the axis of the agitation drive motor 32 to increase the driving force while reducing the rotational speed.

Further, a shaft 46 is axially coupled to the agitation drive motor 32 and is installed extending through the upper part of the inner cylinder 6 to the lower part of the inner cylinder 6, and rotates according to the drive of the agitation drive motor 32. An agitation screw 48 is provided that agitates the food waste contained in the inner cylinder 6 so as to be inverted up and down. The shaft 46 of the agitation screw 48 is directly coupled to the agitation drive motor 32 when the speed reducer 34 is not present, but is axially coupled to the speed reducer 34 when the speed reducer 34 is present. The stir screw 48 has a smaller horizontal width and a larger vertical length as it goes to the lower end thereof, so that the food waste located inside the inner cylinder 6 can be easily inverted up and down during rotation. The stirring screw 48 is formed such that the angle of the screw at the lowermost end is 45 ° with respect to the ground, and the angle of the screw is gradually reduced toward the upper end so that food can be more easily inverted upside down and stirred, preferable.

In the lower part of the case 4, there is provided a collection box 80 having a collection space 84 in which food and beverage waste processed by the inner cylinder 6 is removed, and a handle 82 is installed in the collection box 80.

A shielding plate 52 is provided so that the space between the inner cylinder 6 and the removal box 80 is closed or opened and food and beverages are processed in the inner cylinder 6, and then removed into the removal box 80.

The shielding plate 52 is installed so as to selectively shield the space between the inner cylinder 6 and the collection box 80, and a plurality of settling waters flowing out from the food waste stored in the inner cylinder 6 pass therethrough. A water passage hole 54 is formed. The precipitated water collection tank 56 is coupled to the lower part of the shielding plate 52 to collect the precipitated water that has passed through the water passage holes 54 of the shielding plate 52. A first discharge pipe 60 connected to the settling water collecting tank 56 is installed so as to discharge the settling water collected in the settling water collecting tank 56 to the outside. The shielding plate 52 and the settling water collecting tank 56 shield the space between the inner cylinder 6 and the collection box 80 so that the food waste thrown in through the inlet 8 is accommodated in the inner cylinder 6 and processed. Next, after the processing of the food waste in the inner cylinder 6 is completed through the dehydration and drying process, the food and drink waste processed by the shielding plate 52 and the settling water collecting tank 56 opened between the inner cylinder 6 and the collection box 80. Is removed from the inner cylinder 6 into the removal box 80. When food and drink are dehydrated and dried by the inner cylinder 6, the precipitated water is collected in the precipitated water collecting tank 56 through the plurality of water holes 54 formed in the shielding plate 52. A first discharge pipe 60 is connected to the precipitation water collection tank 56 so that the precipitation water collected in the precipitation water collection tank 56 is discharged to the outside. A check valve 68 is installed in the first discharge pipe 60 so that the precipitated water does not flow backward and can be easily discharged to the outside.

A driving device for enabling the shielding plate 52 and the sediment water collecting tank 56 to selectively shield the space between the inner cylinder 6 and the collection box 80 is necessary. For this purpose, as shown in FIG. 1, the shielding plate 52 and the settling water collecting tank 56 are slidably installed between the inner cylinder 6 and the collection box 80 and connected to the shielding plate 52.

The temperature sensor 38 and the humidity sensor 36 sense the temperature and humidity inside the inner cylinder 6, and the control unit 106 receives the signals sensed from the temperature sensor 38 and the humidity sensor 36 and reaches the set temperature and humidity. Then, the linear actuator is driven. The temperature sensor 38 and the humidity sensor 36 are installed to sense the temperature and humidity inside the inner cylinder 6. However, as shown in FIG. 1, the electrical connection with the control unit 106 is facilitated. It is preferable to be installed between the drive chamber 20 and the inner cylinder 6. The signals sensed from the temperature sensor 38 and the humidity sensor 36 are the temperature and humidity inside the inner cylinder 6, and the temperature and humidity inside the inner cylinder 6 are determined by food and drink waste. The food waste is dehydrated and dried by the stirring screw 48 and the first heater wire 58, whereby the temperature and humidity of the food waste change. In this case, the set temperature and humidity are the temperature and humidity of the food and drink waste in a state where the food and drink are sufficiently dehydrated and dried and the processing is completed, and the control unit 106 controls the temperature sensor 38 and the humidity sensor 36. When the food and drink waste reaches a temperature and humidity in a state where the food and drink are processed, the linear actuator is driven to automatically remove the processed food and drink from the inner cylinder 6 into the bin 80. Thus, the shielding plate 52 is actuated. The control unit 106 is mounted on the PCB 22, is electrically connected to the PCB 22, and is operated by various switches 24, 26, 28, 30 provided on the operation unit 23 exposed to a predetermined part outside the case 4.

The second discharge pipe 62 is connected to the suction fan 40 to discharge the moisture and bad odor to the outside. That is, the moisture and bad odor evaporated when dewatering and drying the food and drink contained in the inner cylinder 6 are sucked by the suction fan 40, and the sucked water and bad odor are discharged to the outside by the second discharge pipe 62. Thus, the user can comfortably use the food and beverage disposal apparatus. In this case, as shown in FIG. 1, a connection port 64 that joins the first discharge pipe 60 and the second discharge pipe 62 for discharging the precipitated water is installed and connected to the connection port 64 to connect the first discharge pipe 60. A third discharge pipe 66 that discharges the precipitated water, moisture, and bad odor merged from the first discharge pipe 60 and the second discharge pipe 62 can be installed. That is, it is possible to more conveniently use the food and beverage disposal apparatus by discharging various leftovers generated from the food and beverage using a single discharge pipe 66 to the outside. By installing a check valve 68 in at least one of the first discharge pipe 60, the second discharge pipe 62, and the third discharge pipe 66, backflow of precipitated water, moisture, and bad odor is prevented.
