Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to an oil storage device for processing pet dog and cat food. Background Technology

[0002] With the continuous expansion of the pet market, the demand for pet dog and cat food production continues to grow. In the pet food processing process, oils, as an important nutrient additive, not only improve the palatability of the feed, but also provide pets with essential fatty acids and energy. The core function of oil storage devices is to maintain the stability of the physicochemical properties of oils, prevent oxidation and rancidity, and ensure that oils have appropriate fluidity during transportation and addition to meet the needs of feed production processes.

[0003] Existing pet dog and cat food oil storage devices mostly use heaters to heat the internal oil to maintain its fluidity and prevent it from solidifying due to low temperatures, which would affect subsequent conveying and addition processes. While this continuous heating method can ensure that the oil is within a suitable working temperature range to a certain extent, it is not the only way to achieve this.

[0004] However, continuous heating causes heat to accumulate inside the device, resulting in localized high temperatures. This not only accelerates the oxidation and deterioration of oils, affecting product quality, but also leads to excessive energy consumption. To address this issue, some devices have introduced temperature sensors for precise heating control. When the temperature reaches a set threshold, the heater automatically stops working; it restarts when the temperature drops. However, while this method can reduce unnecessary heating to some extent, the frequent start-stop of the heater to maintain temperature stability exacerbates equipment wear and tear. Furthermore, due to the lack of an effective heat recovery mechanism, the lost heat cannot be reused, further reducing energy efficiency and failing to meet the growing environmental protection and cost control demands of the pet food processing industry. Therefore, a fat storage device for processing pet dog and cat food is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an oil storage device for processing pet dog and cat food, comprising a storage tank 1 and an insulated tank 2. A collection tank 3 is provided at the bottom of the storage tank 1. A heat recovery mechanism 4 is provided on the right side of the outer wall of the storage tank 1 to retain excess heat and avoid waste. A filter mechanism 5 is provided at the bottom of the storage tank 1. A holding mechanism 6 is provided inside the insulated tank 2. A pressure detection mechanism 7 is provided at the top of the insulated tank 2. A stirring mechanism 8 is provided inside the storage tank 1 to fully mix the oil. A connecting pipe 9 is connected to the left side of the outer wall of the collection tank 3.

[0026] The heat recovery mechanism 4 includes an insulation layer 401, which is fixedly connected to the outer wall of the storage tank 1. The insulation layer 401 surrounds the outer wall of the storage tank 1, preventing internal heat loss and improving insulation performance. An air inlet valve 402 is connected to the left side of the outer wall of the insulation layer 401. The right end of the air inlet valve 402 penetrates the outer wall of the insulation layer 401 and is connected to a copper pipe 403. The copper pipe 403 surrounds the insulation layer 401 and the storage tank 1. The right end of the copper pipe 403 penetrates the inner wall of the insulation layer 401 and is connected to a fan 404. One end of the fan 403 is connected to the air inlet valve 402, and the other end is connected to the fan 404. When the fan 404 is started, heat is released through the air inlet valve 402. 2. External air is drawn into the copper pipe 403, which extracts heat from the insulation layer 401 to prevent excessive internal temperature and achieve temperature control. A diversion pipe 405 is connected to the right side of the fan 404. Two air pipes 406 are connected to the outer wall of the diversion pipe 405, with their right ends connected to the outer wall of the insulation tank 2. The fan 404 is connected to the two air pipes 406 at different locations via the diversion pipe 405. The air pipes 406 connect the upper and lower parts of the insulation tank 2. An exhaust valve 407 is connected to the front of the diversion pipe 405. Switch valves 408 are installed on the outer walls of both air pipes 406, allowing hot gas to pass through the air pipes. 406 allows for air intake and exhaust, and vents excess cold air through exhaust valve 407 to prevent cold air from entering the insulation tank 2 and affecting internal heat storage. A heating component 409 is installed inside the insulation layer 401, including a heater 4091 fixedly connected to the left side of the outer wall of the insulation layer 401. Activating the heater 4091 heats the heating wire 4092 inside the insulation layer 401. One end of the heater 4091 penetrates the outer wall of the insulation layer 401 and is fixedly connected to the heating wire 4092, allowing for uniform heating of the storage tank 1 through the heating wire 4092. The holding mechanism 6 includes a holding box 6. 01. The container 601 is fixedly connected to the inner middle of the heat preservation tank 2. The outer wall of the container 601 is provided with air grooves 602 on all four sides. The container 601 is fixed in the heat preservation tank 2. The ethylene glycol solution is stored in the container 601. The ethylene glycol solution can absorb heat and prevent heat loss. The pressure detection mechanism 7 includes an exhaust port 701, which is connected to the top of the heat preservation tank 2. The outer wall of the exhaust port 701 is equipped with a pressure relief valve 702. The pressure in the heat preservation tank 2 is monitored in real time through the pressure relief valve 702. When the internal pressure is too high, the valve is opened to release the excess gas and prevent damage to the device.

[0027] Specifically, the insulation layer 401 is integrally formed with the storage tank 1 to prevent internal heat loss and thus improve the insulation effect. An air inlet valve 402 is connected to the outer wall of the insulation layer 401. A copper pipe 403 surrounds the insulation layer 401 and the storage tank 1. The air inlet valve 402 and the fan 404 are interconnected through the copper pipe 403. When the fan 404 is started, external air is drawn into the copper pipe 403 through the air inlet valve 402. As the air flows through the copper pipe 403, it draws heat from the interior of the insulation layer 401, preventing excessive internal temperature and thus achieving temperature control. The fan 404 is connected to two air pipes 406 at different locations via a diversion pipe 405 to achieve air diversion. The air pipes 406 connect the upper and lower parts of the insulation tank 2, ensuring that air is evenly distributed inside the insulation tank 2. An exhaust valve 407 is connected to the front of the diversion pipe 405, and a switch valve 40 is installed on the outer wall of both air pipes 406. 8. Hot gas enters and exits through gas pipe 406, and excess cold gas is discharged through exhaust valve 407 to prevent cold air from entering the insulation tank 2 and affecting the internal heat storage. Heater 4091 is fixed on the outside of insulation layer 401. When heater 4091 is activated, heating wire 4092 evenly heats storage tank 1 to ensure that the temperature inside storage tank 1 is maintained at a suitable level. In addition, container 601 is fixed in the middle of the inner side of insulation tank 2 to store ethylene glycol solution. Ethylene glycol solution has good heat absorption properties, which improves the insulation effect of the entire device. Exhaust port 701 is connected to the top of insulation tank 2. Pressure relief valve 702 monitors the pressure in insulation tank 2 in real time. When the internal pressure is too high, the pressure relief valve 702 is opened to release excess gas, avoid damage to the device, and ensure the safe and stable operation of the device.

[0028] Reference Figure 1 , Figure 2 and Figure 5The filtration mechanism 5 includes a discharge pipe 501, which is connected to the bottom of the storage tank 1. The discharge pipe 501 is used to discharge the oil stored inside. To avoid the oil containing a large amount of impurities and iron filings, a connecting end 502 is threaded onto the inner wall of the discharge pipe 501. The bottom end of the connecting end 502 is connected to a folding cylinder 503. A disposable folding cylinder 503 is installed in the middle of the connecting end 502. The folding cylinder 503 adopts a fine mesh folding design and has multiple filter holes 50 evenly opened on its outer wall. 4. The outer wall of the folded cylinder 503 is provided with multiple filter holes 504. The filter holes 504 can filter and block impurities and iron filings in the oil. The outer wall of the discharge pipe 501 is provided with a sealing component 505. The sealing component 505 includes a magnetic ring 5051, which is fixedly connected to the top of the outer wall of the discharge pipe 501. A magnetic sealing cover 5052 is slidably connected to the outer wall of the discharge pipe 501. The magnetic sealing cover 5052 works with the collection tank 3 to achieve a sealing treatment during oil transportation and filtration, preventing external dust from entering.

[0029] Specifically, the discharge pipe 501 is connected to the bottom of the storage tank 1. The main function of the discharge pipe 501 is to discharge the oil from the storage tank 1 for use. However, to prevent a large amount of impurities and iron filings from mixing into the oil, the inner wall of the discharge pipe 501 is threaded to facilitate the installation of the connecting end 502. A folding cylinder 503 is installed in the middle of the connecting end 502. The folding cylinder 503 adopts a fine mesh folding design, which can effectively filter out impurities and iron filings in the oil. During installation, the connecting end 502 needs to be rotated into the discharge pipe 501 to ensure a tight connection. The filter holes 504 can effectively block and filter impurities and iron filings in the oil, providing... To ensure airtightness during the filtration process, a sealing component 505 is installed on the outer wall of the discharge pipe 501. The sealing component 505 includes a magnetic ring 5051, which is fixed to the top of the outer wall of the discharge pipe 501. In addition, a magnetic sealing cover 5052 is slidably installed on the outer wall of the discharge pipe 501. The magnetic sealing cover 5052 works in conjunction with the collection tank 3 to achieve sealing treatment during oil transportation and filtration, effectively preventing the entry of external dust. When it is necessary to disassemble the folded cylinder 503, the operator only needs to lift the magnetic sealing cover 5052 upwards so that it is attracted to the magnetic ring 5051, thus completing the disassembly work conveniently and quickly.

[0030] Reference Figure 1 , Figure 2 and Figure 3The stirring mechanism 8 includes a servo motor 801, which is fixedly connected to the top of the storage tank 1. The output end of the servo motor 801 passes through the top of the storage tank 1 and is fixedly connected to a stirring rod 802. The servo motor 801 drives the stirring rod 802 to stir the oil inside to prevent sedimentation and ensure uniform heating and fluidity. A cleaning component 803 is provided on the outer wall of the stirring rod 802. The cleaning component 803 includes two mounting plates 8031, which are fixedly connected to the left and right ends of the stirring rod 802. Scrapers 8032 are fixedly connected to the opposite sides of the two mounting plates 8031. The scrapers 8032 are set at both ends of the stirring rod 802 through the mounting plates 8031. Driven by the servo motor 801, the scrapers 8032 scrape off the grease on the inner wall to prevent grease residue.

[0031] Specifically, the servo motor 801 is installed at the top of the storage tank 1. When the servo motor 801 is started, it drives the stirring rod 802 to rotate inside the storage tank 1, thereby effectively stirring the oil inside. This stirring action can prevent oil sedimentation, ensure that the oil is heated evenly during the heating process, and maintain good fluidity. In order to further improve the stirring effect and clean the inner wall of the storage tank 1, the scraper 8032 is set at both ends of the stirring rod 802 through the mounting plate 8031. Driven by the servo motor 801, the scraper 8032 can effectively scrape off the grease accumulated on the inner wall of the storage tank 1, thereby avoiding grease residue and ensuring the cleanliness of the storage tank 1 and the quality of the oil.

[0032] Working principle: First, the heater 4091 is activated to heat the inside of the insulation layer 401 through the heating wire 4092. When the temperature inside the storage tank 1 is too high or exceeds a specified degree, the fan 404 is activated, drawing outside air into the copper pipe 403 through the air inlet valve 402. The copper pipe 403 then extracts heat from the inside of the insulation layer 401 to prevent the internal temperature from becoming too high. At this time, the top switch valve 408 is closed, while the bottom switch valve 408 is open, allowing heat to smoothly enter the insulation tank 2 through the diversion pipe 405 and the bottom air pipe 406, and sensing that cold air is about to enter the insulation layer. When the heat is in tank 2, the bottom switch valve 408 is closed simultaneously, and the excess cold air is discharged through the exhaust valve 407 to prevent cold air from entering the heat preservation tank 2. The container 601 contains ethylene glycol solution, which can absorb heat and prevent heat loss, greatly improving heat preservation. When excess gas enters the heat preservation tank 2, the excess gas is released through the pressure relief valve 702. When the heat in the storage tank 1 is insufficient, the top switch valve 408 is opened, and the fan 404 sends the heat in the heat preservation tank 2 back to the insulation layer 401, realizing heat utilization and control.

[0033] Furthermore, the oil is discharged through the discharge pipe 501. To avoid the oil containing a large amount of impurities and iron filings, the connecting end 502 is rotated into the discharge pipe 501. The filter hole 504 can filter and block impurities and iron filings in the oil. At the same time, the folding cylinder 503 adopts a folding design, which can improve the storage of debris and avoid blockage. The magnetic sealing cover 5052, together with the collection tank 3, can achieve the sealing treatment during oil transportation and filtration, preventing external dust from entering. At the same time, when disassembling the folding cylinder 503, the magnetic sealing cover 5052 is lifted up and attached to the magnetic ring 5051 for easy disassembly.
