Description

Technical Field

[0001] This invention relates to the technical field of filtration devices, and more particularly to a braising device with filtration function. Background Technology

[0002] With the rapid development of the catering industry, braised food has become increasingly popular among consumers due to its unique flavor and diverse selection. In traditional braising techniques, although the main ingredients can be removed after the braising process is complete, a large amount of spice residue, meat scraps, and other impurities often remain in the braising broth. These residues not only affect the taste of the braised products and reduce their quality, but more seriously, they provide an ideal growth environment for bacteria or mold, increasing the risk of food spoilage.

[0003] Currently, individual vendors generally use manual filtration to address this issue. The method involves scooping out the braising liquid spoonful by spoonful and pouring it onto a filter cloth for filtration. While simple and direct, this method is time-consuming, labor-intensive, and extremely inefficient, failing to meet the demands of increasingly large-scale production. In large-scale production environments, although specialized filtration equipment is available, the filtered braising liquid must be manually transferred back into the braising vessel. This step not only increases workload but also risks secondary contamination due to improper handling. Furthermore, the filtration equipment requires thorough cleaning after each filtration to ensure cleanliness for the next use, further increasing the workload and reducing overall efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a braising device with a filtration function, which can overcome the shortcomings of existing braising broth, which usually requires manual operation when filtering residues. Even when using special filtration equipment, manual transfer of the filtered braising broth is still required, and the filtration equipment needs to be thoroughly cleaned separately, resulting in low work efficiency.

[0005] The technical solution is as follows: A braising device with a filtration function includes: a braising device body; a controller installed on the side of the braising device body; a first bidirectional vane pump installed on the braising device body; a first connecting pipe, with its two ends respectively connected to the inlet of the first bidirectional vane pump and the braising pot of the braising device body and kept in communication; a second connecting pipe connected to the outlet of the first bidirectional vane pump and kept in communication; a fixing frame connected to the braising device body; a mounting cylinder connected to the fixing frame; and a filter cylinder connected to the inner wall of the mounting cylinder, with the end of the second connecting pipe connected to the filter cylinder. Maintain connectivity; electric push rod, mounted on the fixed frame; lifting plate, connected to the telescopic rod of the electric push rod; vertical pipe, symmetrically slidably connected to the top of the mounting cylinder, and fixedly connected to the lifting plate; annular pipe, connected to the lower end of the vertical pipe and maintaining connectivity, the annular pipe is located inside the mounting cylinder and surrounds the outside of the filter cylinder; nozzles, circumferentially spaced and mounted on the annular pipe; water supply assembly, located on the fixed frame, used to deliver hot water to the vertical pipe; sewage discharge assembly, located at the bottom of the mounting cylinder, used to discharge the filtered residue; storage assembly, located on the braising device body, used to store the filtered braising liquid.

[0006] Furthermore, the water supply components include: a water pump, mounted on a mounting bracket; and a hose, connecting the outlet of the water pump to the upper end of the riser and maintaining communication.

[0007] Furthermore, the sewage discharge assembly includes: a sewage discharge pipe connected to the bottom of the mounting cylinder and kept in communication, and a first control valve installed on the sewage discharge pipe.

[0008] Furthermore, the storage assembly includes: a base frame connected to the braising device body; a storage cylinder connected to the base frame; a top cover placed on top of the storage cylinder; a second bidirectional vane pump mounted on the base frame; a third connecting pipe, with its two ends connected to the inlet of the mounting cylinder and the second bidirectional vane pump respectively and kept in communication; a fourth connecting pipe, with its two ends connected to the bottom of the storage cylinder and the outlet of the second bidirectional vane pump respectively and kept in communication; and a waste discharge mechanism located at the bottom of the storage cylinder for discharging the material inside the storage cylinder.

[0009] Furthermore, the waste discharge mechanism includes: a discharge pipe connected to the bottom of the storage cylinder and kept in communication, and a second control valve installed on the discharge pipe.

[0010] Furthermore, it also includes: a fixed pipe connected to the bottom of the storage cylinder, the lower end of the fixed pipe communicating with the discharge pipe, and a first notch on the side of the fixed pipe; a guide rod connected to the outer wall of the fixed pipe; a lifting rod slidably connected to the guide rod; a hollow ring connected to the end of the lifting rod, and the hollow ring having circumferentially spaced circular holes; a float connected to the top of the hollow ring; an oil discharge pipe, the two ends of which are respectively connected to the bottom of the hollow ring and the top of the fixed pipe and kept in communication; a sealing assembly disposed on the inner wall of the storage cylinder for sealing the end of the oil discharge pipe; and a locking assembly disposed on the float for locking the float.

[0011] Furthermore, the sealing assembly includes: an annular frame connected to the inner wall of the storage cylinder; a drive motor mounted on the top of the annular frame; a rotating rod rotatably connected to the annular frame, with its upper end connected to the output shaft of the drive motor, and a flat surface on its surface; and a rotating tube rotatably connected to the inside of the fixed tube, with its top connected to the lower end of the rotating rod, a second notch aligned with the first notch on the side of the rotating tube, and a through hole on the top of the rotating tube.

[0012] Furthermore, the locking assembly includes: a connecting ring, which is connected to the bottom of the hollow ring and the top of the float respectively; a push rod, which is slidably connected inside the connecting ring, and the end of the push rod is aligned with the plane of the rotating rod surface; and a connecting spring, which is connected to the push rod and the connecting ring at both ends respectively.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The present invention, through the cooperation of the first bidirectional vane pump, filter cylinder, electric push rod, lifting plate, vertical pipe, annular pipe and nozzle, can realize automatic filtration of brine and automatic backwashing of filter cylinder. Specifically, during the filtration process, the first bidirectional vane pump pumps the brine in the brine pot to the filter cylinder for filtration. When the filter cylinder needs to be cleaned, the electric push rod drives the lifting plate to move up and down, so that the vertical pipe and annular pipe connected to it move accordingly. At the same time, the water pump supplies water to the vertical pipe through the hose and sprays hot water from the nozzle to thoroughly backwash the filter cylinder. No manual operation is required, which can improve work efficiency.

[0014] 2. This invention utilizes components such as a second bidirectional vane pump, a third connecting pipe, a fourth connecting pipe, and a storage cylinder to construct a highly efficient brine transfer and storage system. After being processed by the filter cylinder, the brine is drawn from the mounting cylinder by the second bidirectional vane pump and transported to the storage cylinder for temporary storage through the fourth connecting pipe. This process can complete the transfer of brine without manual intervention, which not only saves labor costs but also reduces the risk of secondary contamination of the brine due to improper manual operation. In addition, when the brine needs to be reused, the second bidirectional vane pump can also reverse its operation to transport the brine in the storage cylinder back to the braising device, thereby improving work efficiency.

[0015] 3. This invention utilizes a combination of a fixed pipe, guide rod, lifting rod, hollow ring, float, oil drain pipe, and sealing assembly. As the brine level in the storage cylinder rises, the float drives the hollow ring to an appropriate position. The controller then controls the drive motor to rotate the rotating rod and the connected rotating pipe, thereby opening or closing the end of the oil drain pipe. This effectively removes the lighter oil from the surface of the brine, avoiding the problem of difficult oil removal in traditional methods. This improves the quality of the brine and maintains its original flavor and freshness. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example: A braising device with a filtering function, such as Figures 1-4 As shown, the device includes a braising apparatus body 1, a controller 2, a first bidirectional vane pump 3, a first connecting pipe 4, a second connecting pipe 5, a fixing frame 6, an installation cylinder 7, a filter cylinder 8, an electric push rod 9, a lifting plate 10, a vertical pipe 11, an annular pipe 12, a nozzle 13, a water supply assembly, a sewage discharge assembly, and a storage assembly. The controller 2 is installed on the rear left side of the braising apparatus body 1. The first bidirectional vane pump 3 is installed on the lower front side of the braising apparatus body 1. The inlet of the first bidirectional vane pump 3 is connected to the bottom of the braising pot 101 of the braising apparatus body 1 via the first connecting pipe 4, maintaining communication. The outlet of the first bidirectional vane pump 3 is connected to the second connecting pipe 5. The fixing frame 6 is connected to the right front side of the braising apparatus body 1. The installation cylinder 7 is connected to the fixing frame 6. The bottom of the installation cylinder 7 is conical. A filter cylinder 8 is installed inside the installation cylinder 7. The top of the filter cylinder 8 is fixedly connected to the top of the installation cylinder 7, and the bottom of the filter cylinder 8 is fixedly connected to the bottom of the installation cylinder 7. An annular space is formed between the outer wall of the filter cylinder 8 and the inner wall of the mounting cylinder 7. The bottom of the filter cylinder 8 is designed to be open. The right end of the second connecting pipe 5 is connected to the bottom of the mounting cylinder 7 and remains in communication. The right end of the second connecting pipe 5 is located directly below the filter cylinder 8 so that the first bidirectional vane pump 3 can transport the brine to the inside of the filter cylinder 8 through the second connecting pipe 5. An electric push rod 9 is installed on the right side of the fixing frame 6. A lifting plate 10 is connected to the telescopic rod of the electric push rod 9. Vertical pipes 11 are slidably connected to the top left and right sides of the mounting cylinder 7. The upper parts of the two vertical pipes 11 are fixedly connected to the lifting plate 10. An annular pipe 12 is connected between the lower ends of the two vertical pipes 11 and remains in communication. The annular pipe 12 is located inside the mounting cylinder 7 and surrounds the outside of the filter cylinder 8. Multiple nozzles 13 are installed circumferentially on the inner side of the annular pipe 12. The water supply component is used to transport hot water to the inside of the vertical pipe 11. The sewage discharge component is used to discharge the residue filtered out by the filter cylinder 8. The storage component is used to store the filtered brine.

[0027] like Figure 2 As shown, the water supply assembly includes a water pump 14 and a hose 15. The water pump 14 is installed on the lower left side of the mounting bracket 6. The inlet of the water pump 14 is used to connect to external hot water. The outlet of the water pump 14 is connected to the hose 15 and kept in communication. The upper ends of the two vertical pipes 11 are connected to the hose 15 and kept in communication. The sewage discharge assembly includes a sewage pipe 16 and a first control valve 17. The bottom of the mounting cylinder 7 is connected to the sewage pipe 16 and kept in communication. The first control valve 17 is installed on the sewage pipe 16.

[0028] like Figure 1 and Figure 4As shown, the storage assembly includes a base frame 18, a storage cylinder 19, a top cover 20, a second bidirectional vane pump 21, a third connecting pipe 22, a fourth connecting pipe 23, and a waste discharge mechanism. The base frame 18 is connected to the right side of the braising device body 1, and the storage cylinder 19 is connected to the top of the base frame 18. The top cover 20 is placed on the top of the storage cylinder 19. The second bidirectional vane pump 21 is installed on the front left side of the top of the base frame 18. The inlet of the second bidirectional vane pump 21 is connected to the rear side of the mounting cylinder 7 by the third connecting pipe 22 and is kept in communication. The outlet of the second bidirectional vane pump 21 is connected to the bottom of the storage cylinder 19 by the fourth connecting pipe 23 and is kept in communication. The waste discharge mechanism is used to discharge the material inside the storage cylinder 19. The waste discharge mechanism includes a discharge pipe 24 and a second control valve 25. The bottom of the storage cylinder 19 is connected to the discharge pipe 24 and is kept in communication. The second control valve 25 is installed on the discharge pipe 24.

[0029] When it is necessary to filter the braising liquid in the braising pot 101, the main ingredients in the braising pot 101 must first be removed. Then, the controller 2 controls the first bidirectional vane pump 3 and the second bidirectional vane pump 21 to start working. The first bidirectional vane pump 3 can draw the braising liquid in the braising pot 101 through the first connecting pipe 4 and transport the braising liquid to the inside of the filter cylinder 8 through the second connecting pipe 5. The filter cylinder 8 can filter the braising liquid, leaving the residue inside the filter cylinder 8. The filtered braising liquid will then enter the annular space between the mounting cylinder 7 and the filter cylinder 8. At the same time, the second bidirectional vane pump 21... The filtered brine in the annular space can be extracted through the third connecting pipe 22, and transported to the storage cylinder 19 for temporary storage through the fourth connecting pipe 23. After all the brine has been filtered, the controller 2 controls the first bidirectional vane pump 3 and the second bidirectional vane pump 21 to stop working. Then, the controller 2 controls the electric push rod 9 and the water pump 14 to start working. The water pump 14 can deliver hot water to the nozzle 13 through the hose 15, the vertical pipe 11 and the annular pipe 12. The electric push rod 9 can drive the lifting plate 10, the vertical pipe 11, the annular pipe 12 and the nozzle 13 to reciprocate. The nozzle 13 is lowered to allow hot water to spray from the nozzle 13 to thoroughly backwash the filter cartridge 8, preventing residue from adhering to the filter cartridge 8 and causing blockage. Simultaneously, the first control valve 17 is opened to allow all residue inside the filter cartridge 8 to be discharged through the drain pipe 16, thus automatically completing the cleaning of the filter cartridge 8. After cleaning, the controller 2 stops the electric push rod 9 and water pump 14, and closes the first control valve 17. Then, the controller 2 controls the first bidirectional vane pump 3 and the second bidirectional vane pump 21 to operate in reverse. The second bidirectional vane pump 21, through the fourth connecting pipe 23, can clean the material inside the storage cylinder 19. The brine is extracted and transported to the installation cylinder 7 through the third connecting pipe 22. At the same time, the first bidirectional vane pump 3 can transport the brine in the installation cylinder 7 back to the braising pot 101 for reuse through the second connecting pipe 5 and the first connecting pipe 4. There is no need for manual transfer of the brine, which saves time and effort and improves work efficiency. When it is necessary to clean the inside of the storage cylinder 19, the inside of the storage cylinder 19 can be directly rinsed with water spray equipment. At the same time, the second control valve 25 can be opened so that the wastewater in the storage cylinder 19 can be discharged out through the discharge pipe 24. After the wastewater is discharged, the second control valve 25 is closed.

[0030] like Figures 5-8As shown, it also includes a fixed pipe 26, a guide rod 27, a lifting rod 28, a hollow ring 29, a float 30, an oil drain pipe 31, a sealing assembly, and a locking assembly. The fixed pipe 26 is connected to the bottom center of the storage cylinder 19. The top of the fixed pipe 26 is a closed design, and the bottom of the fixed pipe 26 is an open design. The fixed pipe 26 is located directly above the left end of the discharge pipe 24, and the lower end of the fixed pipe 26 is connected to the discharge pipe 24. A first notch 2601 is opened on the right side of the fixed pipe 26. A guide rod 27 is connected to the rear side of the fixed pipe 26. The guide rod 27 slides on... A lifting rod 28 is connected to the front end of the lifting rod 28, and a hollow ring 29 is connected to the front end of the hollow ring 28. Multiple circular holes 2901 are spaced apart circumferentially on the hollow ring 29. A float 30 is connected to the top of the hollow ring 29. An oil drain pipe 31 is connected between the bottom of the hollow ring 29 and the top of the fixed pipe 26 and remains in communication. A sealing assembly is used to seal the end of the oil drain pipe 31, and a locking assembly is used to lock the float 30. The sealing assembly includes a ring frame 32, a drive motor 33, a rotating rod 34, and a rotating pipe 35. The ring frame 32 is connected to the upper part of the inner wall of the storage cylinder 19. A drive motor 33 is installed at the top center of the ring frame 32. A rotating rod 34 is rotatably connected to the middle of the ring frame 32. The rotating rod 34 passes through the hollow ring 29 and the middle of the float 30, and the upper end of the rotating rod 34 is connected to the output shaft of the drive motor 33. A flat surface 3401 is provided on the rear side of the rotating rod 34. A rotating tube 35 is rotatably connected inside the fixed tube 26, and the top of the rotating tube 35 is connected to the lower end of the rotating rod 34. The top of the rotating tube 35 blocks the lower end of the oil drain pipe 31. The outer wall of the rotating tube 35 is tightly attached to the inner wall of the fixed tube 26. A notch is opened on the right side of the rotating tube 35. The second notch 3501 is aligned with the opening 2601. The top of the rotating tube 35 has a through hole 3502. The top of the fixed tube 26 blocks the area above the through hole 3502. The locking assembly includes a connecting ring 36, a push rod 37 and a connecting spring 38. The bottom of the hollow ring 29 and the top of the float 30 are both connected to the connecting ring 36. The push rod 37 is slidably connected inside the two connecting rings 36. The front ends of the two push rods 37 are aligned with the plane 3401 of the rotating rod 34. The rear ends of the two push rods 37 are connected to the connecting rings 36 with the connecting spring 38.

[0031] Initially, the first notch 2601 and the second notch 3501 are aligned. When wastewater needs to be discharged from the storage cylinder 19, it can directly enter the discharge pipe 24 through the first notch 2601 and the second notch 3501 for discharge. When the fourth connecting pipe 23 delivers brine to the storage cylinder 19, the float 30 floats on the surface of the brine. As more and more brine enters the storage cylinder 19, the float 30 continues to rise, driving the hollow ring 29, the lifting rod 28, and the connecting ring 36 upward. When all the brine has entered the storage cylinder 19, the float 30, the hollow ring 29, the lifting rod 28, and the connecting ring 36 stop rising. Since the density of oil is generally less than that of water, the brine... The oil in the soup will naturally float to the top layer. At this time, the controller 2 can control the drive motor 33 to drive the rotating rod 34 to rotate 180 degrees, so that the plane 3401 on the rotating rod 34 moves away from the top rod 37. The protrusion on the surface of the rotating rod 34 will squeeze the top rod 37 to move backward, and the connecting spring 38 will be compressed. At the same time, the rotating rod 34 will drive the rotating tube 35 to rotate 180 degrees, so that the rotating tube 35 blocks the first notch 2601, and the fixed tube 26 blocks the second notch 3501, so that the brine in the storage cylinder 19 cannot enter the discharge pipe 24. The through hole 3502 will be connected to the lower end of the oil discharge pipe 31, so that the height of the brine is higher than the position of the round hole 2901. All the oil can enter the hollow ring 29 through the round hole 2901, and then be discharged into the discharge pipe 24 through the oil discharge pipe 31, through hole 3502, rotating pipe 35, and fixed pipe 26. Under the elastic force of the connecting spring 38, the end of the push rod 37 can be pressed tightly against the surface of the rotating rod 34 to increase the friction between the push rod 37 and the rotating rod 34, locking the hollow ring 29 and the float 30, preventing them from moving downwards due to the drop in the liquid level in the storage cylinder 19. This allows for the metered discharge of oil from the storage cylinder 19, which not only improves the eating experience but also reduces the risk of oxidative rancidity of the braising liquid, maintains the freshness and original flavor of the braising liquid, and ensures metered oil discharge. After discharge, the controller 2 controls the drive motor 33 to drive the rotating rod 34 to rotate 180 degrees to reset, so that the plane 3401 on the rotating rod 34 is aligned with the top rod 37 again. At this time, the connecting spring 38 will return to its original state, driving the top rod 37 to move forward to reset, so that the front end of the top rod 37 is in contact with the plane 3401 but without pressure. At this time, the hollow ring 29 and the float ball 30 will fall to the surface of the brine due to their own weight, and the rotating rod 34 will drive the rotating tube 35 to rotate 180 degrees to reset, so that the rotating tube 35 blocks the lower end of the oil drain pipe 31 again, the through hole 3502 is no longer connected to the lower end of the oil drain pipe 31, and the second notch 3501 is aligned with the first notch 2601 again.

[0032] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
