Description

Gravity control device of feed molding machine {GRAVITY CONTROL DEVICE OF FISH FARMING FEED FOR MAKING SYSTEM}

The present invention relates to a specific gravity control device of a feed molding machine, and more particularly, to an improved specific gravity control device provided on the barrel side of a feed molding machine for forming fish, pets and livestock feed.

The feed used for fish farming is divided into raw feed and blended feed. Raw feed is a feed that aquaculture companies purchase raw materials (raw meat) and mix them into granular type. Because of the phenomenon of loosening and decomposition, farming in lakes or seas is not suitable because it causes water pollution.

In addition, since it is easily decomposed to moisture, the amount of loss is increased rather than the supply for fish farming and fish farming, and thus the economic loss increases. There are various kinds of harmful bacteria, so they are susceptible to indigestion or disease when feeding.

Formulated feed is cooked and molded by blending raw materials containing various nutrients. It is sterilized and has no deterioration, so it is easy to package, preserve and transport, and is not easily decomposed by moisture. Null is being used.

Conventional feed molding machine 100 for molding the compound feed as described above is as shown in Figure 1 and look at this as follows.

A raw material input part 101 provided in a tank type is provided to form a raw material mixed with various nutrients into a feed, and is connected to the lower part of the raw material input part 101 to be molded from the raw material input part 101. There is provided a fixed-quantity supply part 102 for supplying a suitable amount for receiving the raw material to be molded.

A mixing part 103 is provided which is connected to the discharge port of the fixed quantity supplying part 102 and makes a good state for molding by adding nutritional oil or water to the raw material which is quantitatively supplied, and is connected and mixed with the mixing part 103. Consists of a molding part 104 that receives the raw material and is molded into a granular type.

When forming the sedimentation feed using the feed forming system as described above to maintain a high temperature and high pressure in the interior for sufficient cooking, while maintaining the state as described above to control the specific gravity even if the feed is completed It is difficult to do it, and about 5% of water is often caused by internal pressures varying according to the mixing ratio of the raw materials, the liquid input amount, and the steam input amount, resulting in loss.

In order to solve the above-mentioned injuries, lowering the temperature and pressure during the molding process results in poor cooking, poor binding and poor gelatinization. And cause a decrease in the overall quality of the feed.

In addition, in the production of pet food or livestock feed sufficient cooking while having an optimal degree of swelling is a good feed. The degree of swelling differs according to the type of product and the blending ratio of raw materials. The swelling ratio is determined by the internal pressure of the molding machine. When the swelling ratio is high, the specific gravity of the feed is low, and when the swelling ratio is low, the specific gravity of the feed is high.

In order to solve this problem, the applicant of the present application has received a patent (No. 753763), and the technical contents thereof are described below with reference to FIG. 7.

It is mounted on the molding part 2 of the feed molding system 1 to externally pressurize the internal pressure at the final stage of feed molding so that the molded part 2 pressure is prevented from rising. Specific gravity control device (3) for discharging the furnace is installed.

The specific gravity control device (3) is coupled to the discharge pipe (5) above the connecting pipe (4) drawn out from the forming part (2), the molding part by a motor (6) installed above the discharge pipe (5) Rotate in the direction (2) to prevent the discharge of raw materials, while installing a vertical screw (7) for discharging pressure to the discharge pipe (5).

In the prior art as described above, some of the floating phenomena are eliminated. However, since excessive pressure is generated in the molding machine because the vertical screw is directly connected to the connecting pipe of the molding machine, when the small hole feed is produced, the molding hole is clogged or water If the content is large, the raw material is discharged to the outside through the specific gravity control device.

In the production of small particle feed, when the molding hole is clogged or when the moisture content is high, the raw material is discharged to the outside through the specific gravity control device, and the connection pipe connected to the specific gravity control device is completely exposed at the tip of the molding machine. Because it does not reduce the internal pressure of the molding machine because it is transmitted to the specific gravity control device.

The raw material flowed into the specific gravity control device by the high pressure of the molding machine is not pushed in the molding machine direction by the vertical screw, but is wound on the blade of the vertical screw and rotates together. Accumulated in the block to the discharge pipe eventually stops the motor is impossible to use.

In addition, since the vertical screws have the same blade pitch, the raw materials located between the blades are wound and rotated without being transported down, which causes the above-mentioned inoperable state.

The patent of the present application is effective for the production of large grain feeds with a small size and a small influence on pressure due to the large size of the molding holes, and the production of feeds with less moisture and less internal pressure. Or, if the moisture content is large, there is a disadvantage that does not perform a smooth function.

Accordingly, the present invention is invented to solve the above problems, the raw material input part is provided so as to form the raw material into the feed, and a fixed quantity supply part for supplying a suitable amount to be connected to the lower portion of the raw material input part for molding And a mixing part which is connected to the discharge port of the fixed-quantity supply part to make a good shape and a molding part which is connected to the mixing part and is formed of a molding part which is made of feed and is formed by artificially discharging the internal pressure to the outside.

Aims to increase feed formation by easily discharging only pressure (gas) while suppressing as much as possible. Can be achieved.

The present invention provides a specific gravity control device that can produce a compound feed having an optimum specific gravity by arbitrarily adjusting the pressure inside the molding machine, finely discharged only the pressure (gas) from the molding machine and can suppress the discharge of the raw material during molding as much as possible By simplifying the structure of the specific gravity control device while minimizing its size, it provides ease of installation, operation and use to reduce the cost burden of users and to efficiently control the specific gravity, and to be applied to all feed forming machines.

The pressure control valve 116 is connected to the feed discharge line (L) to facilitate the pressure discharge than in the natural discharge state, the pressure in the screw tube 113 in front of the pressure control valve 116 A pressure gauge 117 for checking the status is provided.

A branch pipe 118 is connected to the opposite position screw tube 113 of the pressure control valve 116, and the branch pipe 118 has a steam valve 119 and a branch pipe 118 for supplying steam when forming a floating feed. And after the end of the work is provided with an air valve 120 for supplying a high pressure air for cleaning the remaining raw material buried in the screw tube 113 inside.

The plug cylinder 112 is provided with a cylindrical cylinder body 121 having a cross-sectional area smaller than the inner cross-sectional area of the molded part 104, the upper portion of the cylinder body 121 is a backflow prevention screw 115 is It is opened so that it can be inserted, and the lower part is left in a state blocked by the blocking plate 122 to prevent excessive pressure of the forming part 104 from flowing.

The blocking plate 122 forms a large number of discharge holes 123 and 124 so that the pressure of the molding part 104 can be discharged, and serves to supply the raw material discharged with the pressure to the molding part 104. Do it.

The discharge holes 123 and 124 may have a diffusion part 125 having a larger diameter at the lower part than the upper part to facilitate the discharge from the upper part to the lower part to facilitate the resupply of raw materials.

The cross-sectional area of the screw tube 113 coupled to the upper portion of the plug cylinder 112 is larger than the plug cylinder 112 so that the pressure on the plug cylinder 112 can be easily dispersed and discharged, the forming part 104 cross-sectional area Much less than the pressure inside the screw tube 113 is less than the pressure inside the forming part 104 to prevent the backflow of the raw material.

The non-return screw 115 is composed of a source screw 126 located in the plug cylinder 112 and a large screw 127 located in the screw tube 113, the plug cylinder 112 and the source screw 126 The spacing between 1.5 mm or less and the spacing between the screw tube 113 and the large screw 127 is 3 mm or less to facilitate the discharge of pressure and to block backflow of raw materials.

The blade pitch of the source crew 126 is formed to be as wide as the volume of the inside of the screw tube 113 containing the large screw 127 to prevent the raw material is trapped between the screw blades.

The inner wall surface of the screw tube 113 has a fine concave groove 130 is disposed radially to form a spiral to prevent the discharged raw material is wound on the backflow prevention screw 115 to rotate together.

Looking at the working relationship of the specific gravity control device 110 of the fish farming and biaxial feed molding machine 100 of the present invention as described above.

When molding the sedimentation type feed or low specific gravity feed, the molding operation is started in a state in which the steam valve 119 connected to the branch pipe 118 of the specific gravity control device 110 is blocked.

While the raw material is pressurized in the discharge direction by the molding part 104, the inside of the molding part 104 is maintained at a high temperature and a pressure state. In the state close to the discharge direction, cooking is almost completed. Because of this to maintain the pressure to the extent that does not affect the normal cooking and the remaining overpressure is to be discharged to the outside through the non-harmonic device (110).

That is, the backflow prevention screw 115 is rotated in the direction of the forming part 104 by the driving means 114 provided on the upper portion of the screw tube 113 connected to the connecting tube 111 provided in the forming part 104. The raw material of the forming part 104 is blocked, and the pressure (gas) is discharged to the upper portion of the screw tube 113 through a minute space between the backflow prevention screw 115 and the inner wall surface of the screw tube 113.

When the pressure of the forming part 104 is discharged to prevent excessive pressure is discharged by the blocking plate 122 provided in the lower portion of the plug cylinder 112 inserted into the connection pipe 111, the blocking plate It is diffused into the screw tube 113 via the plug cylinder 112 through the discharge holes 123 and 124 formed in the 122, and then discharged to the outside through the pressure control valve 116.
