Description

Technical Field

[0001] The utility model relates to the field of hydrolysis tanks, in particular to a hydrolysis tank for producing feather meal. Background Art

[0002] Farmed poultry often encounter situations of pecking themselves or each other, pecking anus, pecking toes, pecking eggs, and even pecking feces, which are collectively referred to as feather pecking or feather pecking. Feather pecking not only seriously affects its value, but also causes complications such as anemia, dermatitis, fragile and easy-to-break feathers, dull fur color, and sometimes the breeding of parasites. Therefore, feather pecking should be prevented and treated as early as possible. Hydrolyzed feather powder contains about 80% to 85% crude protein, and the content of sulfur-containing amino acids ranks first among all natural feeds. The content of valine, leucine, and isoleucine ranks first, but the content of lysine and tryptophan is not high. Hydrolyzed feather powder has a good therapeutic effect on feather pecking.

[0003] Before turning feathers into powder, they usually need to be hydrolyzed. When hydrolyzing feathers, acid-base hydrolysis is usually used, and the feathers are immersed in an acid or base solution of a certain concentration to destroy the disulfide bonds and sulfide-hydrogen bonds in the feathers. However, existing hydrolysis tanks usually do not have a stirring mechanism. If the acid-base solution is not stirred during hydrolysis, the acid-base solution may not be in sufficient contact with the feathers, resulting in uneven hydrolysis reaction, causing some feathers to be over-hydrolyzed while others are not fully hydrolyzed. In addition, the hydrolysis reaction is usually accompanied by temperature changes. If there is no stirring, a temperature gradient may appear in the reactor, thereby affecting the progress and quality of the hydrolysis reaction. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a feather meal production hydrolysis tank, aiming to improve the problem of lack of stirring treatment mechanism in the existing hydrolysis tank.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a hydrolysis tank for producing feather meal, comprising a hydrolysis tank body, wherein a speed regulating motor is fixedly connected to the outer side wall of the hydrolysis tank body, a transmission rod is fixedly connected to the output end of the speed regulating motor, the transmission rod penetrates into the interior of the hydrolysis tank body, a plurality of driving rings are equidistantly sleeved on the outer side wall of the transmission rod, a plurality of stirring rods are fixedly connected to the outer side walls of the plurality of driving rings, a sliding cavity is opened on the inner side walls of the plurality of stirring rods, a driving member is slidably connected to the inner side wall of the sliding cavity, and a tension spring is fixedly connected to the tail of the driving member.

[0007] Preferably, both upper and lower sides of the inner side wall of the sliding cavity are slidably connected with bubble-making plates, the bubble-making plates are hollowed out, and both sides of the bubble-making plates are fixedly connected with mounting protrusions.

[0008] Preferably, a pressing spring is fixedly connected to the outer side wall of the mounting protrusion, one end of the pressing spring away from the mounting protrusion is fixedly connected to the inner side wall of the sliding cavity, and a push plate is slidably connected to the inner side wall of the sliding cavity.

[0009] Preferably, a cutting blade is fixedly connected to the outer side wall of the push plate, and a return spring is fixedly connected to the outer side wall of the push plate.

[0010] Preferably, the end of the stirring rod is provided with a cutting opening corresponding to the cutting blade.

[0011] Preferably, a feeding pipe and a liquid discharge pipe are respectively connected to the upper and lower ends of the hydrolysis tank body, a supporting leg is provided at the bottom of the hydrolysis tank body, and a flip door is provided at the tail of the hydrolysis tank body.

[0012] The beneficial effects of the utility model are:

[0013] By setting a plurality of stirring rods, when the hydrolysis tank body is hydrolyzing feathers, the operator can turn on the speed regulating motor to drive the plurality of stirring rods to rotate, so as to stir the acid and alkali solution in the hydrolysis tank body. Stirring the acid and alkali solution can help the ions in the solution to be evenly distributed more quickly, thereby ensuring that the acid and alkali solution will not be in insufficient contact with the feathers and that a temperature gradient will not occur.

[0014] In the later stage of stirring, the operator can increase the power of the speed regulating motor to drive the stirring rod to rotate quickly. At this time, under the action of a large centrifugal force, the bubble making plate will be thrown out of the stirring rod to make bubbles. The bubbles can make the acid and alkali solutions contact the feathers more evenly, thereby improving the efficiency of the reaction. The cutting blade will also be thrown out of the stirring rod to cut the feathers in the later stage of hydrolysis. The broken feathers can be surrounded by ions in the solution more quickly, thereby accelerating the chemical reaction. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example

[0024] Reference Figure 1-3 A feather meal production hydrolysis tank comprises a hydrolysis tank body 1, wherein the upper and lower ends of the hydrolysis tank body 1 are connected with a feeding pipe 101 and a liquid discharge pipe 106 respectively, a supporting leg 103 is arranged at the bottom of the hydrolysis tank body 1, a flip door 102 is arranged at the tail of the hydrolysis tank body 1, a speed regulating motor 104 is fixedly connected to the outer wall of the hydrolysis tank body 1, a transmission rod 105 is fixedly connected to the output end of the speed regulating motor 104, the transmission rod 105 penetrates into the interior of the hydrolysis tank body 1, a plurality of driving rings 2 are equidistantly sleeved on the outer wall of the transmission rod 105, a plurality of stirring rods 201 are fixedly connected to the outer walls of the plurality of driving rings 2, a knife outlet 207 corresponding to the cutting blade 205 is opened at the end of the stirring rod 201, and a sliding cavity 202 is opened on the inner wall of the plurality of stirring rods 201;

[0025] It should be noted that the reason why feathers are not cut in the early stage of hydrolysis is that feathers are mainly composed of keratin, which is a hard and elastic protein. In the early stage of acid-base hydrolysis, the chemical substances have not completely destroyed the peptide bonds in the keratin. At this time, the feathers are still relatively tough and cannot be cut by the cutting blade 205. In the late stage of hydrolysis, the peptide bonds in the keratin of the feathers are broken, and the fiber structure of the feathers will be destroyed to a greater extent, making them fragile. At this time, the feathers will be more easily cut or torn by the cutting blade 205.

[0026] Reference Figure 4-5 The upper and lower sides of the inner wall of the sliding cavity 202 are slidably connected with bubble making plates 208, and the bubble making plates 208 are hollowed out. Both sides of the bubble making plates 208 are fixedly connected with mounting protrusions 210, and the outer wall of the mounting protrusions 210 is fixedly connected with a pressing spring 209. The end of the pressing spring 209 away from the mounting protrusion 210 is fixedly connected to the inner wall of the sliding cavity 202. The inner wall of the sliding cavity 202 is slidably connected with a push plate 211, and the outer wall of the push plate 211 is fixedly connected with a cutting blade 205. The outer wall of the push plate 211 is fixedly connected with a return spring 206. The inner wall of the sliding cavity 202 is slidably connected with a driving member 203, and the tail of the driving member 203 is fixedly connected with a tension spring 204.

[0027] It should be noted that the acid-base solution mentioned in the present technical solution is one of an acidic or alkaline solution. The acidic solution may be hydrochloric acid or phosphoric acid, and the alkaline solution may be sodium hydroxide.

[0028] The working principle of the hydrolysis tank for feather meal production:

[0029] When in use, the operator can add feathers to be hydrolyzed into the hydrolysis tank body 1 through the feeding tube 101. After the feathers enter the hydrolysis tank body 1, the operator can turn on the heater in the hydrolysis tank body 1 to heat one of the acid-base solutions in the hydrolysis tank body 1. The heated acid-base solution will destroy the disulfide bonds and other chemical bonds in the feathers, making the structure of the feathers loose until the feathers can be easily broken. In the process of hydrolyzing the feathers with the acid-base solution, in order to ensure more complete hydrolysis, the operator can turn on the speed regulating motor 104 to drive the multiple stirring rods 201 to rotate and stir the acid-base solution through the driving ring 2. When the multiple stirring rods 201 rotate and stir the acid-base solution, the ions in the solution can be distributed more evenly faster, avoiding the phenomenon of insufficient contact between the acid-base solution and the feathers and the occurrence of temperature gradients. When the hydrolysis process enters the later stage, the operator can increase the power of the speed regulating motor 104, so that the transmission rod 105 drives the multiple stirring rods 201 to rotate rapidly. When the multiple stirring rods 201 rotate rapidly, a large centrifugal force will be generated, so that the driving member 203 overcomes the tension of the tension spring 204 and is thrown to the outside of the stirring rod 201. In the process of the driving member 203 being thrown to the outside of the stirring rod 201, the contact slope of the driving member 203 will slowly push the two bubble making plates 208 out of the stirring rod 201. When the bubble making plates 208 pushed out of the stirring rod 201 stir the acid and alkali solution as the stirring rod 201 rotates, the solution passes through the hollow bubble making plates 208 and generates a pressure difference around the small holes, prompting air to escape from the holes, thereby generating bubbles. The generation of bubbles makes the acid and alkali solution contact the feathers more evenly, thereby improving the efficiency of the reaction.

[0030] When the driving member 203 moves outward to push out the two bubble making plates 208, as the driving member 203 continues to move outward, the end of the driving member 203 will contact the push plate 211 and push the cutting blade 205 out of the stirring rod 201 through the blade outlet 207. The cutting blade 205 that leaks out of the stirring rod 201 will cut the feathers in the late stage of hydrolysis as the stirring rod 201 rotates and stirs, and cut the feathers into smaller pieces. Under heating conditions, the broken feathers can be more evenly dispersed in the solution, which helps to maintain the uniform temperature of the entire reaction system and avoid local overheating or failure to reach the reaction temperature, thereby ensuring the smooth progress of the hydrolysis reaction and the hydrolysis effect. When the feathers are hydrolyzed in the hydrolysis tank body 1, After completion, the operator can turn off the speed regulating motor 104 to stop the transmission rod 105 from rotating. At this time, the driving member 203 will return to its original position under the tension of the tension spring 204. Without the push of the driving member 203, the two bubble making plates 208 will also return to their original positions under the elastic force of the pressing spring 209, and the cutting blade 205 will also retract into the stirring rod 201 under the elastic force of the reset spring 206, so as to be convenient for the next use. When the transmission rod 105 stops rotating, the operator can discharge the acid-base solution in the hydrolysis tank body 1 out of the hydrolysis tank body 1 through the drain pipe 106, and then open the flip door 102 to take out the feathers after hydrolysis, and proceed to the next step (this is the prior art and will not be elaborated in detail).

[0031] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
