Description

Technology Field

[0001] The present invention relates to a rice husk compression device, and more specifically, to a rice husk compression device that compresses fed rice husks by applying pressure in the front-back and left-right directions, and allows for convenient adjustment of the amount of fed rice husks through a sensor. Background Technology

[0002] Generally, a large amount of rice husk is generated as a byproduct during the rice milling process. Due to its high recycling value, this husk is utilized for various purposes, including fuel, animal feed, soil conditioners, and adsorbents. However, the large volume and low density of rice husk have posed a problem of poor space efficiency during storage and transportation. Furthermore, consistent product production has been hindered not only by milling equipment but also by differences in density depending on the rice husk variety.

[0003] To address this issue, various compression devices have been proposed to increase the density of rice husks and facilitate storage and transportation. Conventional rice husk compression devices generally utilize screws or rollers to compress the husks in a unidirectional manner. However, this method suffers from low or non-uniform compression efficiency, resulting in inconsistent compression strength and the problem of the compressed rice husks easily disintegrating.

[0004] In addition, existing devices have had problems such as overloading of the compression device due to excessive input or difficulty in obtaining the desired compression strength due to insufficient input, as the amount of rice husk input is not adjusted to reflect the variety and density of the rice husk. To improve this, there is a need for a sensor and control system capable of automatically adjusting the input amount. Prior art literature

[0024] In describing the configuration and operation of the rice husk pressing device (1) of the present invention, the definition of direction is as follows.

[0025] The forward and backward directions are defined based on the movement path of the rice husk leading from the first compression chamber (100) of the rice husk compression device (1) to the second compression chamber (200), and specifically, the direction in which the rice husk is compressed and proceeds through the first compression chamber (100) is defined as the 'forward' direction.

[0026] The left and right directions are defined based on the compression direction applied during the process in which the rice husk is finally compressed in the second compression chamber (200) to form a molded product, and are formed perpendicular to the first compression chamber (100). Specifically, the direction in which the rice husk is compressed and proceeds through the second compression chamber (200) is defined as the 'right direction'.

[0028] Referring to FIGS. 1 to 10, a rice husk compression device (1) according to the first embodiment of the present invention may include an input hopper (10), a first compression chamber (100), a second compression chamber (200), and a control unit (300).

[0029] The input hopper (10) is where the rice husk is input, and it serves to receive the raw material, the rice husk, in the initial stage of the rice husk compression device (1) and transfer it to a subsequent process. Preferably, the upper part has a structure that is wider at the top and narrower at the bottom, allowing the rice husk to be supplied smoothly through a discharge part connected to the first compression chamber (100).

[0030] The first compression chamber (100) is connected through the discharge part of the input hopper (10) to receive rice husks, and may be equipped with a first compression means (120) that moves through the first cylinder (110) and a sensor moving means (130) that moves the touch sensor (140).

[0031] The first cylinder (110) reciprocates the first compression means (120), and the first compression means (120) can compress the fed rice husks in the forward and backward directions while pushing them out.

[0032] The first compression means (120) may include a shielding plate (121) that opens and closes the discharge portion of the input hopper (10) and a compression plate (122) formed vertically downward from the shielding plate (121) to compress the input rice husk.

[0033] Referring to FIGS. 1 to 4, when the first compression means (120) moves backward by the operation of the first cylinder (110), the shielding plate (121) retracts and the discharge part opens and closes. At this time, the degree of opening and closing of the discharge part is adjusted according to the degree of retraction of the shielding plate (121), so that the amount of rice husk discharged can be adjusted.

[0034] Additionally, the rice husk extrusion device (1) includes a touch sensor (140) and a control unit (300) to allow the degree of opening and closing of the discharge unit to be precisely controlled. The touch sensor (140) detects when the first compression means (120) retracts by more than a predetermined distance and transmits a signal to the control unit (300). The control unit (300) controls the first cylinder (110) according to the signal from the touch sensor (140) to stop the retraction of the first compression means (120), thereby controlling the degree of opening and closing of the discharge unit.

[0035] In detail, the signal regarding the retraction distance of the first compression means (120) detected by the touch sensor (140) is used by the control unit (300) to determine whether it has reached an appropriate retraction position according to the amount of rice husk to be discharged. The user can set the amount of rice husk to be discharged through an input device (e.g., touchscreen, keypad, or external terminal) connected to the control unit (300).

[0036] At this time, the touch sensor (140) may be composed of any one of a limit switch, an optical sensor, a micro switch, or a pressure sensing sensor that detects physical contact or pressure of the first compression means (120) and generates an electrical signal. That is, the touch sensor (140) may be placed on the movement path of the first compression means (120) and may provide position information of the first compression means (120) to the control unit (300) through a switching operation that opens and closes the circuit at the moment one side of the first compression means (120) touches it, and preferably, the contact member (1211) of the shielding plate (1211) may be configured to contact the touch sensor (140).

[0037] These touch sensors (140) can be repositioned within the first compression chamber (100) and can be moved in the forward and backward directions by means of a sensor moving means (130).

[0038] The sensor moving means (130) is installed in the first compression chamber (100) and is equipped with a touch sensor (140) so that the position of the touch sensor (140) can be moved back and forth in a straight line in the forward and backward directions. The sensor moving means (130) may include a guide (132) installed on one or more walls of the first compression chamber (100) and a moving member (131) that slides along the guide (132) in the forward and backward directions and has a touch sensor (140) at one end.

[0039] The moving member (131) of the sensor moving means (130) may be configured in a manual manner in which its position is adjusted by pushing and pulling with the user's hand, and may be operated in conjunction with a separate manual operating lever. When configured in an automatic manner, a linear actuator may be applied, and it may be any one of a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or a ball screw driven by an electric motor.

[0040] In addition, the control unit (400) can be electrically linked with the first cylinder (110), second cylinder (210), third cylinder (242), discharge door (230), operating cylinder (530) of the present invention and the fixing means (400) described below to control the operation performed in the rice husk compression.

[0041] Referring to FIGS. 1 and FIGS. 6 to 9, the second compression chamber (200) is formed to be perpendicular to the first compression chamber (100), so that the rice husk, which has been compressed in the front-rear direction in the first compression chamber (100), is molded by receiving additional pressure in the left-right direction, thereby efficiently reducing the volume of the rice husk and performing a compression process to obtain a molded product of uniform density and high quality.

[0042] The second compression chamber (200) is provided with a second compression means (220) that moves through a second cylinder (210) to push out the rice husk compressed by the first compression means (120), a pressurizing part (240) positioned opposite the second compression means (220) to restrict the movement of the rice husk pushed out by the second compression means (200) so that the rice husk is compressed in the left and right directions, and a discharge door (230) through which the compressed rice husk is discharged.

[0043] Referring to FIGS. 1 to 7, the pressurizing unit (240) may include a support frame (241) installed on the upper outer surface of the second compression chamber (200), a third cylinder (242) provided on the support frame (241), and a pressurizing means (243) connected to the third cylinder (242).

[0044] The pressurizing means (243) is connected to the third cylinder (242) and moves in the up and down direction, but when the rice husk compression operation is performed, it moves in the downward direction to restrict the movement of the rice husk being pushed out from the second compression means (220) so that the rice husk is compressed in the left and right directions between the second compression means (220).

[0045] When the compression of rice husks in the left and right directions in the second compression chamber (200) is finished, the pressurizing means (243) is moved upward by the third cylinder (242) to open a movement path so that the rice husks can move toward the discharge door (230).

[0046] Referring to FIGS. 7 to 9, when the discharge door (230) is closed, the second compression means (220) pushes the rice husk toward the discharge door (230) and then retracts briefly, and then, when the discharge door (230) is opened, the second compression means (220) moves again to discharge the rice husk molded product to the outside.

[0047] The discharged rice husk molded material is received in a bag that is pre-placed on the discharge door (230). This bag is mounted in a state of precise alignment with the discharge door (230) to reliably receive the rice husk molded material. After the rice husk molded material is completely received in the bag, the bag is transferred to a separate sealing device that seals the opening by sealing it. This sealing device firmly seals the opening of the bag by heat sealing, adhesive tape, or other sealing methods to prevent the rice husk molded material from being exposed to the outside and to maintain its quality during storage and transportation.

[0048] Meanwhile, in the second compression chamber (200), one or more walls may have air discharge holes (201) formed therein to discharge air between the rice husks when compressing the rice husks. Referring to FIGS. 1 and FIGS. 10, a larger compressed rice husk product can be manufactured by first making compressed rice husks and then making new compressed rice husks in a second step and overlapping them as needed. At this time, while the compressed rice husks made in the first step and the compressed rice husks made in the second step are overlapping, air between the first compressed rice husks and the second compressed rice husks can be discharged through the air discharge holes (201).

[0050] Hereinafter, a rice husk pressing device according to the second embodiment of the present invention will be described in detail.

[0052] FIG. 11 is a perspective view of a rice husk pressing device according to a second embodiment of the present invention, and FIG. 12 is an example of the operation of a rice husk pressing device according to a second embodiment of the present invention.

[0054] Referring to FIGS. 11 and 12, the rice husk pressing device according to the second embodiment of the present invention may be substantially the same as the rice husk pressing device according to the embodiment of the present invention described above, except that it further includes a fixing means (500).

[0055] The fixing means (500) may include a fixing plate (510), a roller member (520), and an operating cylinder (530), and is provided to fix a collection bag (b) mounted on the discharge door (230) side of the second compression chamber (200).

[0056] The fixing plate (510) is formed on at least one outer surface of the second compression chamber (200), and although it is exemplified in FIG. 9 and FIG. 10 as being formed on the upper and lower surfaces of the second compression chamber (200), it may also be formed on the left and right surfaces, or formed on all four surfaces to increase the fixing force of the collection bag.

[0057] The roller member (520) is connected to the fixed plate (510) through a hinge shaft, and the roller (521) allows the collection bag (b) to be attached to the outer surface of the second compression chamber (200) to fix its position, and the roller (521) is made of a material with high friction, such as rubber, to prevent the collection bag (b) from coming off and to fix it stably.

[0058] The operating cylinder (530) is connected to the roller member (520) and, as it contracts or expands, causes the roller (521) to be in close contact with or separated from the outer surface of the second compression chamber (200). Specifically, the part of the operating cylinder (530) that supports the roller member (530) is formed to be slidably movable on the roller member (530) according to the operation of the operating cylinder (530), so that the roller member (530) rotates around a hinge axis according to the contraction or expansion operation of the operating cylinder (530), thereby allowing the roller (521) to be in close contact with or separated from the outer surface of the second compression chamber (200).

[0060] The rice husk pressing device according to the first and second embodiments of the present invention has the advantage of being able to change the position of the touch sensor (140) without stopping the device during operation. Since the density of the material, rice husk, varies by variety, the operator must adjust the amount of rice husk being pressed by frequently changing the position of the touch sensor (140) during the operation of the device, thus improving efficiency in terms of time and cost in manufacturing the pressed rice husk.

[0062] Although embodiments of the present invention have been described above, the spirit of the present invention is not limited to the embodiments presented in this specification. Those skilled in the art who understand the spirit of the present invention may easily propose other embodiments within the scope of the same spirit by adding, changing, deleting, or adding components, and such embodiments shall also be considered to fall within the scope of the spirit of the present invention.
