Description

Technical Field

[0001] The present invention belongs to the technical field of feed cooling, and relates to a cooling device, in particular to an efficient cooling device for liquid feed and a cooling method thereof. Background Art

[0002] Feed is the general term for the food of all animals raised. Narrowly speaking, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than a dozen varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils and fats, meat and bone meal, grains, and feed additives. Nowadays, in the production process of feed on the market, automated production is required in the processing workshop according to different production volumes. During the production process in the feed processing workshop, especially in the hot summer months from July to September, the temperature in the feed processing workshop is high, resulting in high temperature and slow cooling of the feed after production, which will cause problems such as feed mildew and low feed moisture, greatly shortening the shelf life of the feed and reducing the input-output ratio of production.

Application No.: 202310642002.X; Publication No.: CN 116892814 A

[0004] Although this patent cools and humidifies the feed in the tank body, however, carbohydrates and proteins in the feed will undergo chemical reactions during storage, generating gases such as carbon dioxide and nitrogen. In addition, microbial activities will also cause the generation of gases. If these gases are not processed in time, it will cause feed caking and mildew, affecting the quality and nutritional value of the feed. Summary of the Invention

A plurality of impellers are rotatably connected in the water channel. Each impeller is coaxially fixedly connected to the corresponding auxiliary plate. An endothermic pipeline is wound around the cooling cylinder. A first conveying interface is fixed on the water supply tank. A first infusion pump is fixed on the first conveying interface. The input end of the first infusion pump is connected to the first conveying interface, and the output end of the first infusion pump is fixed with a first infusion pipeline.

[0008] The working principle of the present invention is as follows: Different types of feeds can be dispensed through multiple feed dispensing tanks to prevent different feeds from contacting each other. Since the storage conditions and shelf lives of different feeds are different, premature contact is likely to cause mildew or mutual contamination. Then, the various feeds are mixed by a mixing assembly, and the gas entrained in the feeds is dissipated during the mixing process to prevent the feeds from caking and mildewing and maintain the feeds in good condition. After mixing, the feed mixture can be transported to the material gathering tank through a conveying assembly. The feed mixture flows into the feed cooling channel through the material gathering tank, and the water liquid in the water liquid channel and the heat absorption pipe absorbs the heat entrained in the feed mixture to achieve the effect of cooling the feed. Moreover, since the feed mixture is thick, its flow rate in the feed cooling channel is too slow. The rotation of the impeller is driven by the flow of the water liquid in the water liquid channel. After the impeller rotates, it drives the auxiliary plate to rotate. After the auxiliary plate in the feed cooling channel rotates, it will assist in stirring the liquid feed, increasing the flow rate of the liquid feed in the feed cooling channel and increasing the contact area between the liquid feed and the air, improving the heat dissipation effect. After the liquid feed is cooled, it flows into the discharge cavity to complete the work of cooling and discharging.

[0009] The mixing assembly includes a stirring rod rotatably connected in the mixing cavity and a servo motor 1 fixed to the feed mixing tank. The output shaft of the servo motor 1 is coaxially and fixedly connected to the stirring rod. The stirring rod is divided into a main rod and a plurality of support rods fixed on the main rod. A driving assembly is arranged in the main rod. One end of each support rod is rotatably connected with a scraping rubber strip, and the rotation angles between adjacent scraping rubber strips differ by 90°. The scraping surface of each scraping rubber strip contacts the cavity wall of the mixing cavity. A plurality of vibrating rods are fixed on each support rod, and a metal hollow ball is fixed on each vibrating rod. A knocking assembly for knocking the metal hollow ball is arranged in each vibrating rod. A transmission assembly is arranged in each support rod. Each transmission assembly is connected to the driving assembly, and each transmission assembly is connected to the corresponding scraping rubber strip. Each knocking assembly is connected to the corresponding transmission assembly.

[0010] With the above structure, the servo motor 1 can drive the stirring rod to rotate. After the stirring rod rotates, the mixing of the feed can be achieved. Then, the driving assembly is used to control the scraping rubber strip to clean the cavity wall of the mixing cavity during the mixing process to prevent the feed from adhering to the cavity wall of the mixing cavity. Then, the driving assembly drives the transmission assembly to operate, and the transmission assembly further drives the knocking assembly to knock the metal hollow ball, causing the metal hollow ball and the knocking assembly to resonate and dissipating the gas entrained in the feed.

[0011] The conveying assembly includes a conveying screw rotatably connected in the feeding channel and a servo motor 2 fixed in the feed cooling tank. The output shaft of the servo motor 2 is coaxially and fixedly connected to the conveying screw.

[0012] With the above structure, the conveying screw can be driven by the second servo motor to rotate. After the conveying screw rotates, it will convey the liquid feed into the material gathering tank, and further shear and extrude the feed mixture during the conveying process to improve the mixing degree.

[0013] The driving assembly includes a mounting rack inside the feed stirring tank and a driving main rod fixed on the mounting rack. A driving cavity is formed inside the main rod part of the stirring rod. The bottom end of the driving main rod is rotatably connected to the driving cavity.

Each driving bevel gear I meshes with the corresponding driving bevel gear II, and each driving bevel gear II is connected to the corresponding transmission assembly.

[0014] With the above structure, the whole stirring rod can be rotated, while the driving main rod remains stationary. The plurality of driving bevel gears II rotatably connected inside the driving cavity are driven to rotate by meshing with the corresponding driving bevel gears I. After each driving bevel gear II rotates, it will drive each transmission assembly to rotate.

[0015] The transmission assembly includes a transmission rotating rod rotatably connected inside the branch rod part of each stirring rod, and a plurality of transmission bevel gears I coaxially fixed on each transmission rotating rod. A transmission bevel gear II is rotatably connected inside the branch rod part of each stirring rod. Each corresponding transmission rotating rod is coaxially and fixedly connected to the corresponding driving bevel gear II, and each transmission bevel gear II is connected to the corresponding knocking assembly.

[0016] With the above structure, the transmission rotating rod can be driven to rotate by the driving bevel gear II. After the transmission rotating rod rotates, it will drive the transmission bevel gear I to rotate. After the transmission bevel gear I rotates, it will drive the transmission bevel gear II to rotate, and the transmission bevel gear II will then drive the knocking assembly to operate.

[0017] The knocking assembly includes a driving seat arranged inside each vibrating rod and a mounting groove formed on each driving seat. Each driving seat is coaxially and fixedly connected to the corresponding transmission bevel gear II. Each mounting groove is filled with a knocking block. A wavy annular groove is formed at the bottom of each knocking block. And a sliding block I is fixed inside each mounting groove. Each sliding block I is in sliding fit with the corresponding annular groove. And a guiding ring is fixed inside each vibrating rod. Each guiding ring sleeves the corresponding knocking block. And a guiding chute is formed on each knocking block. A guiding slider is fixed inside each guiding ring. Each guiding chute is in sliding fit with the corresponding guiding slider. And one end of each knocking block is in knocking fit with the corresponding metal hollow ball.

[0018] With the above structure, the driving seat can be driven to rotate by the second transmission bevel gear. After the driving seat rotates, the sliding block one and the annular groove are in sliding fit to drive the knocking block to move up and down reciprocally. The knocking block realizes the knocking action on the metal hollow ball through this up and down reciprocating motion.

[0019] A ventilation and heat dissipation fan facing the top of the material collecting tank is fixed to the top of the feed cooling tank. An infusion pump two is fixed to the top of the water liquid supply tank. A water pumping pipeline is fixed to the input end of the infusion pump two. The water pumping pipeline communicates with the inside of the water liquid supply tank. A water conveying pipeline is fixed to the output end of the infusion pump two. One end of the water conveying pipeline communicates with the conveying channel.

[0020] With the above structure, the liquid feed on the material collecting tank can be cooled by wind by the ventilation and heat dissipation fan, and the water liquid is conveyed into the conveying pipeline by the infusion pump two, so that the water liquid can enter the stirring cavity and be mixed with the feed to form liquid feed.

[0021] A second feed conveying pump and a third feed conveying pump are fixed inside the feed cooling tank. A feed outlet is opened on the feed cooling tank. And the discharging cavity is connected with the bottom end of the feed conveying channel through the second feed conveying pump. The feed outlet is connected with the discharging cavity through the third feed conveying pump.

[0022] With the above structure, if the temperature of the liquid feed still does not reach the standard when flowing into the discharging cavity, the liquid feed can be re-injected into the feed conveying channel through the second feed conveying pump and cooled again, so as to reach the cooling standard, and then the cooled liquid feed is conveyed through the third feed conveying pump.

[0023] A feeding trough is fixed on the fixed bottom plate. A water outlet is opened on the water liquid supply tank. A water stop valve is fixed inside the water outlet. And the output ends of the water outlet and the feed outlet are both facing the upper part of the feeding trough.

[0024] With the above structure, the cooled liquid feed can be injected into the feeding trough for animals to eat, and the water liquid supply tank supplies water to the feeding trough to facilitate animals to drink.

[0025] The present invention also provides an efficient cooling method for liquid feed, including:

[0026] S1. Clean the equipment: Remove sundries, dust and waste materials in the equipment to ensure the cleanliness of the equipment;

[0027] S2. Disinfect the equipment: Use a disinfectant to thoroughly disinfect the cooling equipment, kill pathogens and bacteria, and prevent the spread of diseases;

[0028] S3. Prepare the feed: According to the age, breed and growth stage of the animals to be raised, select appropriate feed types and formulas to ensure that the animals can obtain sufficient nutrition.

[0029] S4. Store feed: According to the feed formula, different types of feed are separately packed in each feed packing tank to prevent different types of feed from coming into contact, reducing the occurrence of mildew or mutual contamination;

[0030] S5. Mix feed: According to the formula, different types of feed flow into the mixing chamber. Through mixing treatment, the uniformity of feed mixing is improved, and the gas entrained in the feed is dissipated during the mixing process to prevent feed caking and mildew and maintain the good state of the feed;

[0031] S6. Feed cooling: After the feed is mixed, it flows into the feeding channel. During the transportation by the conveying screw in the feeding channel, the feed mixture is further sheared and extruded to improve the mixing degree until the feed mixture is transported into the cooling cylinder for cooling. The feed mixture flows in the spiral flow holes. Since the outer wall of the cooling cylinder is wound with heat absorption pipes and the water liquid channel is opened inside the cooling cylinder, both inside and outside the cooling cylinder have the ability of heat absorption and heat dissipation to quickly dissipate the heat of the feed mixture;

[0032] S7. Inspect temperature: After the liquid feed is cooled, a small amount of sample is extracted from the discharge cavity by the third feed pump. Personnel use temperature measuring equipment such as a thermometer to measure the temperature of the sample. When it is found that the temperature does not meet the standard, the remaining liquid feed in the discharge cavity is extracted by the second feed pump and extracted into the feeding channel for further cooling until the liquid feed reaches the desired temperature.

[0033] Compared with the prior art, the high-efficiency cooling device for liquid feed and its cooling method have the following advantages:

[0034] 1. Different types of feed are separately packed by multiple feed packing tanks to prevent different feeds from coming into contact with each other. Since the storage conditions and shelf life of different feeds are different, premature contact is likely to cause mildew or mutual contamination.

[0035] 2. Various feeds are mixed by the mixing component, and the gas entrained in the feed is dissipated during the mixing process to prevent feed caking and mildew and maintain the good state of the feed.

[0036] 3. The heat entrained in the feed mixture is absorbed by the water liquid in the water liquid channel and the heat absorption pipe to achieve the effect of feed cooling. Moreover, since the feed mixture is thick, the flow rate in the feed cooling channel is too slow. The rotation of the impeller is driven by the flow of the water liquid in the water liquid channel. After the impeller rotates, it will drive the auxiliary plate to rotate. After the auxiliary plate in the feed cooling channel rotates, it will assist in stirring the liquid feed, increasing the flow rate of the liquid feed in the feed cooling channel and increasing the contact area between the liquid feed and the air, improving the heat dissipation effect.

[0067] With the above structure, the cooled liquid feed can be injected into the feeding trough 56 for animals to eat, and the feeding trough 56 can be supplied with water through the water supply tank 4 to facilitate animals to drink.

[0068] Working principle of the present invention: Different types of feeds are divided and packaged through multiple feed packaging tanks 7 to prevent contact between different feeds. Since the storage conditions and shelf lives of different feeds are different, premature contact is likely to cause mildew or mutual contamination. According to the formula, different types of feeds flow into the mixing chamber 5, and the stirring rod 27 is driven to rotate by the first servo motor 28. After the stirring rod 27 rotates, the mixing of the feeds can be achieved. The entire stirring rod 27 rotates, while the driving main rod 35 remains stationary. A plurality of second driving bevel gears 38 rotatably connected in the driving chamber 36 are driven to rotate by meshing with the corresponding first driving bevel gears 37. The transmission rotating rod 39 is driven to rotate by the second driving bevel gear 38. After the transmission rotating rod 39 rotates, the first transmission bevel gear 40 is driven to rotate. After the first transmission bevel gear 40 rotates, the second transmission bevel gear 41 is driven to rotate. The driving seat 42 is driven to rotate by the second transmission bevel gear 41. After the driving seat 42 rotates, the knocking block 44 is driven to perform reciprocating up and down motion through the sliding fit between the first sliding block 46 and the annular groove 45. The knocking block 44 performs a knocking action on the metal hollow ball 31 through this reciprocating up and down motion, so as to dissipate the gas entrained in the feed during the mixing process, prevent the feed from caking and mildewing, and maintain the good state of the feed. After mixing is completed, it can be transported to the feed conveying channel 11 through the first feed pump 12. Then, the conveying screw 32 is driven to rotate by the second servo motor 33. After the conveying screw 32 rotates, the liquid feed is transported into the material gathering tank 14, and the feed mixture is further sheared and extruded during the transportation process to improve the mixing degree. The feed mixture is transported into the material gathering tank 14, and the feed mixture flows into the feed cooling channel 17 through the material gathering tank 14. The water liquid in the water liquid channel 16 and the heat absorption pipeline 21 absorbs the heat entrained in the feed mixture to achieve the effect of cooling the feed. Moreover, since the feed mixture is thick, the flow rate in the feed cooling channel 17 is too slow. The water liquid flowing in the water liquid channel 16 drives the impeller 20 to rotate. After the impeller 20 rotates, the auxiliary plate 18 is driven to rotate. After the auxiliary plate 18 in the feed cooling channel 17 rotates, it will assist in stirring the liquid feed, improve the flow rate of the liquid feed in the feed cooling channel 17, and increase the contact area between the liquid feed and the air to improve the heat dissipation effect. After the liquid feed is cooled, it flows into the discharge chamber 15. If the temperature of the liquid feed still does not reach the standard when it flows into the discharge chamber 15, the liquid feed can be re-injected into the feed conveying channel 11 through the second feed pump 58 and cooled again to reach the cooling standard. Then, the cooled liquid feed is transported through the third feed pump 48. The cooled liquid feed is injected into the feeding trough 56 for animals to eat, and the feeding trough 56 is supplied with water through the water liquid supply tank 4 to facilitate the animals to drink.

[0069] In summary, different types of feeds are dispensed through multiple feed dispensing tanks 7 to prevent different feeds from contacting each other. Since the storage conditions and shelf lives of different feeds are different, premature contact can easily lead to mildew or cross-contamination. Then, the various feeds are mixed by the mixing assembly, and the gas entrained in the feeds is dissipated during the mixing process to prevent the feeds from caking and mildewing, maintaining the good state of the feeds. After mixing, the feed mixture can be conveyed into the material gathering tank 14 through the conveying assembly. The feed mixture flows into the feed cooling channel 17 through the material gathering tank 14, and the water liquid in the water liquid channel 16 and the heat absorption pipe 21 absorbs the heat entrained in the feed mixture to achieve the effect of cooling the feed. Moreover, since the feed mixture is thick, the flow rate in the feed cooling channel 17 is too slow. The water liquid flowing in the water liquid channel 16 drives the impeller 20 to rotate. After the impeller 20 rotates, it drives the auxiliary plate 18 to rotate. After the auxiliary plate 18 in the feed cooling channel 17 rotates, it will assist in stirring the liquid feed, increasing the flow rate of the liquid feed in the feed cooling channel 17, and increasing the contact area between the liquid feed and the air, improving the heat dissipation effect. After the liquid feed is cooled, it flows into the discharge cavity 15 to complete the work of cooling and discharging the material.

[0070] The present invention also provides an efficient cooling method for liquid feeds, including:

[0071] S1. Cleaning the equipment: Remove the sundries, dust, and waste materials in the equipment to ensure the cleanliness of the equipment;

[0072] S2. Disinfecting the equipment: Use a disinfectant to thoroughly disinfect the cooling equipment to kill pathogens and bacteria and prevent the spread of diseases;

[0073] S3. Matching the feeds: According to the age, breed, and growth stage of the animals to be raised, select the appropriate types and formulas of feeds to ensure that the animals can obtain sufficient nutrition.

[0074] S4. Storing the feeds: According to the feed formula, different types of feeds are dispensed into each feed dispensing tank 7 to prevent different types of feeds from contacting each other and reduce the occurrence of mildew or cross-contamination;

[0075] S5. Mixing the feeds: According to the formula, different types of feeds flow into the mixing chamber 5. Through the mixing process, the degree of uniform mixing of the feeds is improved, and the gas entrained in the feeds is dissipated during the mixing process to prevent the feeds from caking and mildewing, maintaining the good state of the feeds;

[0076] S6. Feed Cooling: After the feed is mixed, it flows into the feeding channel 11. During the conveying process by the conveying screw 32 in the feeding channel 11, the feed mixture is further sheared and extruded to improve the mixing degree until the feed mixture is conveyed into the cooling cylinder 13 for cooling. The feed mixture flows in the spiral flow holes 19. Since the heat absorption pipe 21 is wound around the outer wall of the cooling cylinder 13 and the water liquid channel 16 is provided inside the cooling cylinder 13, both the inside and outside of the cooling cylinder 13 have the ability to absorb and dissipate heat, so as to quickly dissipate the heat of the feed mixture.

[0077] S7. Temperature Inspection: After the liquid feed is cooled, a small amount of sample is extracted from the discharge chamber 15 by the third feed pump 48. Personnel use temperature measuring equipment such as a thermometer to measure the temperature of the sample. When it is found that the temperature does not meet the standard, the remaining liquid feed in the discharge chamber 15 is extracted by the second feed pump 58 and pumped into the feeding channel 11 for cooling again until the liquid feed reaches the desired temperature.
