Description

Feed Pellet Double Cooler System

The present invention relates to a feed pellet cooler system, and in particular, to a double cooler system for improving feed pellet productivity.

Feed for livestock feed, fish meal, or compost is produced in various types of pellets of various sizes and shapes. These feed pellets are manufactured through processes such as mixing, gelatinizing and compression molding, cooling and shipping of various materials depending on the intended use, such as livestock feed or fish meal. For example, feed pellets that are gelatinized and compressed through a pellet mill are concerned about moisture generation and deterioration of the product when packaged immediately due to the high heat generated during the gelatinization and compression process, so they are cooled through a cooler before packaging. or shipped via conveyor belt.

However, in the process of producing feed pellet products, when various items of feed pellets (e.g., 10 items, etc.) are cooled through one cooler, the items being cooled must be emptied from the cooling tank and then replaced with other items. It must be put into the cooling tank to ensure that items are not mixed and can be safely shipped.

Therefore, while the feed pellets of the next item to be processed can be put into the cooler, productivity is reduced due to the waiting time until the item currently being cooled is completely cooled and completely discharged from the cooling tank, that is, the item replacement time. There is a problem that arises. For example, if an item replacement time of 13 minutes is required in a cooler that processes about 5 tons per processing time, and there are item replacements 13 times a day, 3 hours of downtime per day may occur.

Patent Application No. 10-2013-0074811 (2013.06.27.) may be referred to as a related document.

Therefore, the present invention was created to solve the above-mentioned problems, and the purpose of the present invention is to use one cooler in the same space without expanding the cooler equipment, but to process two feed pellet items through two paths. The aim is to provide a feed pellet double cooler system that allows simultaneous processing of the next item to be processed without item replacement time and improves productivity.

First, to summarize the features of the present invention, the double cooler system for cooling feed pellets according to one aspect of the present invention for achieving the above object is one of the first and second falling paths of the injected pellets. 2-way damper to select above; A cooling tank that accommodates and cools the pellets falling through the 2-way damper and has a blocking wall to separate the pellet receiving space on the first and second falling paths; Controls the amount of pellets discharged from the cooling tank, and includes a first discharge controller disposed at a position corresponding to the first falling path and a second discharge controller disposed at a position corresponding to the second falling path. discharge control unit; And performing control to select at least one of the first and second falling paths of the 2-way damper, and at least one of the first and second discharge controllers of the discharge control unit. It includes a control device that performs control to adjust the amount of the pellets discharged.

The two-way damper includes first opening and closing means for rotating a first opening and closing plate fixed to a first rotating shaft on the first falling path and a second rotating shaft on the second falling path according to the control of the control device. It includes a second opening and closing means for rotating the fixed second opening and closing plate.

Each of the first and second discharge controllers includes a grid having openings through which pellets exit; an opening/closing element array having opening/closing elements corresponding to the openings, the opening/closing elements being coupled to move simultaneously; and an opening and closing means that closes or opens the openings by moving the opening and closing elements left and right according to the control of the control device.

And, a method of operating a double cooler system including a 2-way damper, a cooling tank, and a discharge control unit on the falling extension line of the injected feed pellet according to another aspect of the present invention is: (A) the first of the 2-way damper While the falling path is blocked and the pellets of the second item are cooled by dropping them into the second pellet receiving space separated by the blocking wall of the cooling tank through the second falling path of the 2-way damper, the second falling path is blocking and dropping pellets of a first item through the first falling path into a first pellet receiving space separated by the blocking wall of the cooling tank; (B) discharging the pellets of the second item cooled in the second pellet receiving space on the second falling path of the cooling tank using the second discharge controller of the discharge control unit under the control of the control device. ; and (C) discharging the pellets of the first item cooled in the first pellet receiving space on the first falling path of the cooling tank using the first discharge controller of the discharge control unit.

The operating method of the double cooler system is (D) after discharging all the pellets of the second item cooled in the second pellet receiving space using the second discharge controller, the first and second items of the two-way damper are Open all of the second falling paths, accommodate the pellets of the first item using both the first and second pellet receiving spaces, and use both the first and second discharge controllers of the discharge control unit to accommodate the pellets of the first item in the cooling tank. It further includes discharging the cooled pellets of the first item from the first and second pellet receiving spaces.

According to the feed pellet double cooler system according to the present invention, one cooler is used in the same space without adding cooler equipment, but it is possible to process two feed pellet items simultaneously through two paths, so that the next product can be processed without time for item replacement. Items to be processed can be processed continuously and productivity can be improved.

In most existing feed factories, facilities are arranged according to the process order from top to bottom within the building, and the surrounding area is narrow, so there is no space to add additional cooler facilities. Considering that the capacity of the cooler is usually 3 tons, 5 tons, etc., it is not easy to expand the space to add such facilities within the space of the existing building. The improved type of cooler of the present invention can be easily installed by modifying existing cooler equipment within an existing space, and it is possible to replace the existing fixed condition of other equipment such as a pellet mill being in operation during the time the product stays in the cooler and cools the product. Breaking away from the concept, it is expected that there will be a productivity improvement of about 20% or more in current facilities that process more than 3 tons.

In the feed pellet double cooler system 100 according to the present invention, one cooler is used in the same space without expanding cooler equipment, but two feed pellet items are processed through two paths, reducing item replacement time. It is possible to improve productivity by enabling continuous processing of the next processing item.

Hereinafter, the operation of the feed pellet double cooler system 100 according to an embodiment of the present invention will be described in more detail with reference to the flowchart of FIG. 4.

Figure 4 is a flowchart for explaining the operation of the feed pellet double cooler system 100 according to an embodiment of the present invention.

The feed pellet double cooler system 100 of the present invention includes a 2-way damper 120, a cooling tank 110, and a discharge control unit 130 provided on the falling extension line of the input feed pellets, which controls Depending on the control of the device 190, it may process a single item of pellets using both the first and second fall paths, may use only one of the two paths, or may operate by blocking both paths. You can also leave it in a stopped state. Here, at the time when processing of one item (second item) is completed, continuous cooling is performed using one cooling tank 110 of the single feed pellet double cooler system 100 without time to replace the item with another item (first item). Explains how the cooling process takes place. In other words, we will look at the process of continuously receiving and cooling other items without stopping the operation of other equipment such as the pellet mill during the time the pellets remain in the cooling tank 110 of the double cooler system 100 and cooled.

Referring to FIG. 4, first, the first pellet receiving space 111 of the first falling path of the cooling tank 110 of the feed pellet double cooler system 100 of the present invention and the second pellet receiving space of the second falling path. It is assumed that the cooling process for the pellets of the second item was performed using all of 112 or only the second pellet receiving space 112.

At this time, for example, when replacement of the item to be cooled (e.g., replacement of the second item with the first item) is required, the amount of remaining cooling treatment of the second item currently being cooled is reduced to the second pellet receiving space (112). ), if it is within the amount (e.g., 1 ton) accepted, under the control of the control device 190, the first opening and closing plate 411 of the 2-way damper 120 is closed to block the first falling path -The second falling path can be opened by opening the second opening/closing plate 412 of the way damper 120 (S110).

Accordingly, the pellets (S111) of the second item being introduced are sent to the second pellet receiving space (112) separated by the blocking wall (115) of the cooling tank (110) through the second falling path of the 2-way damper (120). It can be cooled by dropping (S112).

While the pellets of this second item are all received and cooled in the second pellet receiving space 112, the second opening and closing plate 412 of the 2-way damper 120 is opened under the control of the control device 190. Close it to block the second falling path to prevent it from mixing with the first item to be processed subsequently (S113).

In addition, while the pellets of the second item are cooled in the second pellet receiving space 112, the first opening and closing plate of the 2-way damper 120 is manually or under the control of the control device 190 (S114) 411) is opened to open the first falling path (S210), and the pellets (S211) of the first item introduced accordingly fall through the first falling path of the 2-way damper 120 to the blocking wall of the cooling tank 110. It can be cooled by dropping it into the first pellet receiving space 111 divided by (115) (S212).

Meanwhile, while receiving the pellets of the first item into the first pellet receiving space 111, in the second falling path, after S112 and S113, for example, according to the height signal of the level detection sensor 222, for a suitable period of time (e.g., 10 minutes) at or above a height (e.g., 500 kg height) or for an appropriate period of time (e.g., 10 minutes) after starting to receive pellets into the second pellet receiving space 112, the second pellet receiving space. After the pellets of the second item of 112 are cooled, they are cooled in the second pellet receiving space 112 on the second falling path of the cooling tank 110, either manually or under the control of the control device 190. The pellets of the second item can be discharged using the second discharge controller 132 of the discharge control unit 130 (S115). For example, according to the control of the control device 190, the opening and closing means 138 can close or open the openings 352 by moving the opening and closing elements of the opening and closing element array 322 left and right. This open state can be controlled so that the pellets in the pellet receiving space 112 pass through the openings 352 and fall toward the discharge hopper 140.

Thereafter, similarly, in the first falling path, for example, the pellet is dropped for an appropriate time (e.g., 10 minutes) or above a predetermined height (e.g., 500 kg height) according to the height signal of the level detection sensor 221. 1 After the pellets of the first item in the first pellet receiving space 111 have cooled for a suitable period of time (e.g., 10 minutes) after starting to receive them into the pellet receiving space 111, manually or by using the control device 190. According to the control, the pellets of the first item cooled in the first pellet receiving space 112 on the first falling path of the cooling tank 110 are transferred to the first discharge controller 131 of the discharge control unit 130. It can be discharged using (S213). For example, according to the control of the control device 190, the opening and closing means 136 can close or open the openings 351 by moving the opening and closing elements of the opening and closing element array 312 left and right, and the openings 351 ) can be controlled in an open state so that the pellets in the pellet receiving space 111 pass through the openings 351 and fall toward the discharge hopper 140.

In addition, in step S115, when all of the pellets of the second item are discharged from the second pellet receiving space 112 through the discharge hopper 140, manually or under the control of the control device 190, 2- The second opening and closing plate 412 of the way damper 120 is opened to open the second falling path (S116), and the pellets of the first item (S211) introduced accordingly are dropped through the second falling path of the 2-way damper 120. The pellets of the first item can be further accommodated and cooled by falling into the second pellet receiving space 112 separated by the blocking wall 115 of the cooling tank 110 through the path (S311).

That is, while the first falling path of the 2-way damper 120 is open in step S210, the second falling path of the 2-way damper 120 is also opened in step S116, and the first pellet receiving space 111 ) and the second pellet receiving space 112 to receive the pellets of the first item, thereby using both the first discharge controller 131 and the second discharge controller 132 of the discharge control unit 130 to cool the tank. The pellets of the first item cooled in the first pellet receiving space 111 and the second pellet receiving space 112 of (110) can be discharged through the discharge hopper 140 (S312).

In the process of discharging the pellets in the pellet receiving space 111/112, such as steps S115, S213, and S312, through the discharge hopper 140, for example, a predetermined level is determined according to the height signal of the level detection sensor 221/222. After a predetermined period of time (e.g., 10 minutes) at a height or higher (e.g., 500 kg height) or after starting to receive pellets into the pellet receiving space (111/112), for an appropriate period of time (e.g., 10 minutes) of the pellet receiving space. The pellets may be cooled, and then the control device 190 accumulates the first discharge controller 131 and the second discharge controller 132 in each of the first pellet receiving space 111 and the second pellet receiving space 112. The cooled pellets can be discharged in an appropriate discharge amount and controlled to be discharged through the discharge hopper 140. In addition, this discharge process can be carried out simultaneously with the process of receiving pellets into the corresponding pellet receiving space (111/112), that is, the time of pellet input through the 2-way damper 120 and the pellet receiving space (111) It is also possible that the discharge time from /112) to the discharge hopper 140 overlaps, resulting in a time when both operations are performed simultaneously.

At this time, each of the opening and closing means (136, 138) moves the opening and closing elements of each opening and closing element array (312, 322) left and right according to the control of the control device 190, and opens the openings (351, 351) according to the amount of left and right movement. By closing or opening the opening amount of 352 to an appropriate amount, the discharge amount of pellets in the pellet receiving space 111/112 passing through the

openings

351 and 352 and falling toward the discharge hopper 140 can be adjusted.

As described above, in the feed pellet double cooler system 100 according to the present invention, one cooler is used within the same space without expanding cooler equipment, but two feed pellet items can be processed simultaneously through two paths. By doing so, the next item to be processed can be processed continuously without item replacement time, thereby improving productivity. In most existing feed factories, facilities are arranged according to the process order from top to bottom within the building, and the surrounding area is narrow, so there is no space to add additional cooler facilities. Considering that the capacity of the cooler is usually 3 tons, 5 tons, etc., it is not easy to expand the space to add such facilities within the space of the existing building. The improved type of cooler of the present invention can be easily installed by modifying existing cooler equipment within an existing space, and it is possible to replace the existing fixed condition of other equipment such as a pellet mill being in operation during the time the product stays in the cooler and cools the product. Breaking away from the concept, it is expected that there will be a productivity improvement of about 20% or more in current facilities that process more than 3 tons.

As described above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , those of ordinary skill in the field to which the present invention pertains will be able to make various modifications and variations without departing from the essential characteristics of the present invention. Therefore, the spirit of the present invention should not be limited to the described embodiments, and the scope of the patent claims described later as well as all technical ideas that are equivalent or equivalent to the scope of this patent claim are included in the scope of the rights of the present invention. It should be interpreted as
