Description

Pressurized compost granulation device {PRESSURIZED GRANILATION DEVICE}

The disclosed technology relates to a pressurized compost granulation apparatus.

In the method of granulating organic compost including livestock manure, a screw or wheel is installed at regular intervals with a die caster, and the compost is forcibly pushed through a groove perforated in the die caster by the compression force of the screw and wheel. A method of transforming into a cylindrical shape is used. This process is called granulation or pelletization of compost. However, in the case of the screw method, when the moisture content of the raw material is around 30%, the shape of the extruded pellet is maintained, so good processing effect can be expected only by using compost with a low moisture content as the raw material. Because the processing effect is good when the moisture content is around 20%, there is a disadvantage that compost with lower moisture than the screw method should be used as a raw material. That is, since the compost used in the two methods must be put into the device in a state in which the moisture content is reduced, a separate process of evaporating the moisture using a dryer or the like is required.

However, since the moisture content of the compost produced at the current composting facility is around 50%, it is necessary to lower the moisture of the produced compost in order to use the above two granulation devices. Therefore, since it undergoes a separate water evaporation process, a lot of time and energy are required to granulate the compost, resulting in high cost.

Referring to Korean Patent Registration No. 10-2000421 (Title of the Invention: Pellet Forming Apparatus), a technology for producing pellet-type compost by pressing the compost disposed on a molding plate with a pressure roller is disclosed. However, since this method is a method using a wheel, there is a disadvantage that the moisture of the compost has to be lowered to about 20%, and there is a problem that the moisture content of the manufactured pellets is not constant.

The disclosed technology is to provide a pressurized compost granulation apparatus for producing a pellet-type compost in which the moisture content is kept constant around 50%.

A first aspect of the disclosed technology in order to achieve the above technical problem is a hopper for supplying a certain amount of compost through an opening formed below, and a molding plate having a plurality of through-holes arranged at regular intervals and into which compost supplied from the hopper is inserted. , A pair of support parts for supporting the compost and the load of the molding plate by sliding the molding plate from one side is formed, and a groove is formed in which both ends of the molding plate are engaged, and is in close contact with the lower surface of the molding plate and the plurality of A pressurized compost granulation device comprising a pedestal for supporting the compost not to flow down to the bottom of the through hole and a pressure cylinder for applying pressure to the compost inserted into the plurality of through holes by lowering the pressure plate located in the air to the upper surface of the forming plate is to provide

1 is a side view of a pressurized compost granulation apparatus according to an embodiment of the disclosed technology; Referring to FIG. 1 , the pressurized compost granulation apparatus includes a hopper 110 , a forming plate 120 , a support 130 , a pedestal 140 , and a pressure cylinder 150 .

The hopper 110 supplies a certain amount of compost through an opening formed below. The hopper 110 is formed in a funnel shape and compost is introduced therein. Then, by opening or closing the lower opening, compost is supplied to the forming plate. In order to more efficiently process the supply of compost, a plurality of hoppers 110 may be provided. For example, a plurality of molded plates are provided at regular intervals according to the size of the molded plate, and compost can be supplied at each location.

The molding plate 120 is arranged at regular intervals to form a plurality of through-holes into which the compost supplied from the hopper 110 is inserted. According to an embodiment of the disclosed technology, the compost supplied from the hopper 110 falls to the upper surface of the forming plate 120 .

On the other hand, the plurality of through-holes formed in the forming plate 120 may maintain a constant distance from each other. The arrangement and number of through-holes may be different depending on the size of the forming plate 120 . However, it is preferable to maintain the same distance so that the compost inserted into each through-hole can receive pressure evenly from each other.

On the other hand, the plurality of through-holes are formed to be narrowed in diameter by a predetermined depth from top to bottom. For example, assuming that the depth of the through hole is 10 cm, a diameter of 5 cm from the top to the center may be gradually narrowed, and a diameter of 5 cm from the center to the bottom may be maintained. This is to make it easier when compost can be easily introduced when the process starts and when the finished pellet-type compost is taken out at the end of the process.

The support part 130 is provided in pairs, one on each left and right of the forming plate 120 . The support 130 has grooves formed at both ends in which the molding plate 120 engages. The groove formed in the support part 130 may vary slightly depending on the thickness and the shape of the edge of the forming plate 120 . For example, when the edge shape of the molding plate 120 is formed in a circular arc, the groove of the support part 130 may be formed in a circular arc resembling the edge of the molding plate. Of course, since both ends of the forming plate 120 are engaged with the groove of the support part 130 , the size of the groove of the support part 130 is formed to be larger.

Meanwhile, the forming plate 120 is slidably coupled from one side of the support 130 . For example, it may be coupled while sliding from one side to the other side based on the direction in which the groove of the support unit 130 is formed. As a result, the forming plate 120 and the support unit 130 maintain a combined state while the compost pelletizing process is in progress and support the load of the compost supplied to the upper surface of the forming plate 120 and the forming plate.

The pedestal 140 is in close contact with the lower surface of the molding plate 120 . And it supports so that compost does not flow out from the plurality of through-holes formed in the forming plate 120 . That is, it serves to prevent the compost from flowing down the plurality of through-holes. Of course, it may also serve to support the load of the forming plate 120 together with the support 130 .

In the conventional case, the compost, in which moisture has evaporated somewhat, is pushed into the through hole and granulated, but the compost passes through the through hole by rotating a screw or rotating a wheel in order to transmit the pushing force. However, in this case, when the moisture content of the inserted compost is rather high, there is a problem that proper granulation does not occur.

In order to solve this problem, when the moisture in the compost is evaporated in the pre-treatment step, a problem in that the load on the motor driving the screw or wheel is increased in order to pass the hardened compost through the narrow through hole also occurred. Therefore, in the disclosed technology, the lower surface of the forming plate 120 is blocked by using the pedestal 140 to properly process the granulation by applying sufficient pressure to the compost inserted into the through hole.

On the other hand, the pedestal 140 may determine the time of removal from the molding plate using various types of sensors. Here, the point of removal from the forming plate means the point at which the pellets are completed. Preferably, it is possible to detect the time when the pellets are completed using a pressure sensor. The pedestal 140 is connected to a driving device capable of combining or detaching the components of the device, and the processor of the driving device may remove the pedestal or maintain the pedestal state by receiving a sensing value from the sensor.

On the other hand, the pedestal 140 may be further connected to a device for generating vibration in order to make the processing state of the pellets more uniform. For example, it is possible to prevent the formation of a non-uniform air layer inside the pellets by constantly generating minute vibrations when the pellets are processed. The pedestal 140 has a fixed shaft connected to one side by a hinge, so that it can be separated and combined from the molding plate 120 .

The pressure cylinder 150 lowers the pressure plate 150b located in the air to the upper surface of the molding plate 120 . The pressure plate 150b is connected to the end of the pressure cylinder 150, and as the pressure cylinder 150 descends, the pressure plate 150b also descends. The pressure cylinder 150 may apply pressure until the lower surface of the pressure plate 150b and the upper surface of the molding plate 120 meet each other. According to this process, it is possible to apply pressure to the compost inserted into the plurality of through-holes of the forming plate 120 .

On the other hand, on the lower surface of the pressing plate (150b), the forming pin (150a) is formed at a position coincident with the plurality of through holes. The forming pin 150a is formed so that pressure can be applied intensively above the through hole, and in order to properly granulate all the compost being manufactured, the forming pin 150a of the same shape for each through hole is formed so that pressure can be applied. . The pressure cylinder 150 may apply pressure to the upper surface of the forming plate 150a according to a preset cycle. For example, it is possible to receive information about the time it takes to produce a pellet-type compost containing about 50% of moisture, the number of times of applying pressure, and the like, and apply pressure to the platen by the number of times. As this process is repeated, the compost inserted into each through hole is granulated in the form of pellets.

On the other hand, it is possible to granulate the pellets even in the process of applying pressure once without applying pressure several times. In this case, it is possible to detect the pressure applied to each pellet by using a sensor that detects a pressure value so that a uniform pressure is applied to the pellets in one pressurization process.

On the other hand, the pressure cylinder 150 may use the forming pin 150a to collect the completed pellet-type compost inserted into the through-hole after the pelletizing process is completed. In one embodiment, when it is determined that the processing of the pellet is completed through the sensor, the lower part of the through hole is in an open state by sliding or opening and closing the pedestal, and the forming pin 150a presses the upper part of the completed pellet once again to make the pellet. can be pushed down. As shown in FIG. 5, the portion protruding from each of the forming pins 150a pushes the completed pellets, thereby effectively separating the pellets from the through-holes.

On the other hand, between the hopper 110 and the molding plate 120 is provided with a distribution device 160 that moves the upper surface of the molding plate left and right in order to evenly distribute the compost to the molding plate. When using the funnel-shaped hopper 110, it is possible to supply compost by cutting a predetermined amount, but it is difficult to insert the compost into all the through holes of the forming plate 120 in a short time. Therefore, it is possible to shorten the time for compost to be inserted into the through hole by using the distribution device 160 . As shown in FIG. 1 , one end of the distribution device 160 is fixed, and the compost can be evenly distributed while rotating left and right based on the fixed part.

On the other hand, on the other side of the fixed end of the dispensing device 160 is provided with a brush device (160a). The brush device 160a may remove unnecessary compost from the process by sweeping away the excess compost from the upper surface of the forming plate 120 . The distribution device 160 rotates left and right about a fixed point on one side of the body as an axis, and the length of the body is sequentially decreased so that the length of the body is sequentially reduced so that the brush device 160a passes the upper surface of the forming plate 120 . can be reduced That is, the compost is evenly spread while the body rotates, and the excess compost remaining thereafter may be operated in such a way that the brush device 160a sweeps it down. The removed compost may be supplied to the hopper 110 again.

Figure 2 is a view showing an apparatus for collecting the completed pellet-type compost. Referring to FIG. 2 , the completed pellet-type compost is introduced into the collection groove 210 . In one embodiment, when the pressure cylinder pushes the pressure plate downward and pressure is applied, a plurality of forming pins formed on the lower surface of the pressure plate apply pressure to each through hole, and in this state, when compost is granulated, provided in the lower part of the forming plate By removing the pedestal and pushing the pressure plate downward once again, the forming pins can push each pellet downward.

On the other hand, the pressure cylinder can control the pressure plate in two ways in performing the pelletizing process. First, you can apply pressure while moving the platen itself from top to bottom. That is, it may be to apply pressure to the compost in the through hole by repeatedly moving in the vertical direction in a state where the pressure plate is fixed at the end of the pressure cylinder.

Second, in a state in which the pressing plate is lowered to the upper surface of the upper platen, only the pressing cylinder may be repeatedly moved in the vertical direction to apply pressure to the pressing plate. In this case, when the pressure cylinder is lowered, the pressure plate connected to the end is separated, and pressure can be evenly applied to the upper surface of the molding plate with the weight of the pressure plate, and by repeatedly pressing the pressure plate in this state, the pressure can be transmitted to the pellets more efficiently.

On the other hand, the suction fan 220 is installed on one side of the collection groove. The suction fan 220 introduces air into the collection groove to remove odors generated from the pellet-type compost or to prevent dust from entering the pellet-type compost. Of course, it is also possible to prevent the compost from being crushed or stuck during movement by evaporating the moisture on the surface of the pellet-type compost.

3 is a view showing a molding plate 120 for molding compost. A plurality of through-holes are formed in the forming plate 120 . It is possible to form a large number of through-holes in the molding plate 120 as much as possible, since manufacturing a plurality of pellet-type compost in one process can improve manufacturing efficiency. Preferably, the through-holes may be formed in a grid shape as shown in FIG. 3 . Of course, the through-holes may be formed in other shapes under the premise that the same pressure is applied.

4 is a view showing the shape of a plurality of through-holes 120a formed in molding. Referring to FIG. 4 , the plurality of through-holes 120a are formed to be narrower in diameter by a predetermined depth from the upper side to the lower side. In FIG. 4 , a portion having a narrower diameter and a diameter maintained with respect to the central portion are illustrated, but a portion having a narrower diameter may have a smaller specific gravity and a portion in which the diameter is maintained may have a smaller specific gravity.

FIG. 5 is a view showing the molding pin 150a formed on the pressing plate 150 . Referring to FIG. 5 , the forming pin 150a is formed to engage with portions in which diameters of the plurality of through-holes are narrowed. Due to this shape, it is possible to efficiently transmit pressure to the compost inserted into the through hole.

On the other hand, the amount of compost inserted into the plurality of through-holes can be adjusted in consideration of the molding pin (150a) is inserted. For example, compost can be filled only in the area where the diameter is maintained, or a slightly larger amount than that.

The pressurized compost granulation apparatus according to an embodiment of the disclosed technology has been described with reference to the embodiment shown in the drawings for better understanding, but this is merely exemplary, and those of ordinary skill in the art can make various modifications therefrom And it will be understood that other equivalent embodiments are possible. Accordingly, the true technical protection scope of the disclosed technology should be defined by the appended claims.
