[0002] Wood vinegar is a mixed liquid byproduct produced during the dry distillation of biomass materials, which contains a variety of organic matter, inorganic salts, and suspended particles. The raw liquid of wood vinegar production needs to be processed after collection. During the dry distillation process, wood vinegar will contain a certain amount of solid particles and suspended matter, such as tar, carbon black, plant fiber, etc. Through filtration, these suspended matter and particles can be effectively removed to improve the clarity of wood vinegar;

[0003] The traditional technology of collecting wood vinegar uses a filter for filtration. When cleaning the filter screen, the machine needs to be stopped. The replacement method of the filter cartridge will increase maintenance costs and time, affect production efficiency, and have the problem of low production efficiency. Frequent shutdowns are required to replace and clean the filter cartridge, which affects production progress and costs. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a raw liquid collecting device for producing wood vinegar.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A raw liquid collecting device for wood vinegar production comprises a collecting tank and a switchable filter element, wherein a discharge pipe is arranged at the bottom of the collecting tank; the switchable filter element comprises a square structured shell, a circular through hole A opened at the center of the shell, two rectangular slots opened at both sides of the shell and connected to the circular through hole A in an up-down staggered arrangement, a screen changing plate respectively plugged in with the two rectangular slots, and a hydraulic cylinder respectively pushing the screen changing plate to switch between a working station and a non-working station; an upper flange pipe and a lower flange pipe are respectively arranged at the upper and lower ends of the shell, the upper flange pipe is flange-jointed with the discharge pipe, and the lower flange pipe is flange-jointed with the liquid discharge pipe.

[0007] The collecting tank is used to collect the raw liquid in the wood vinegar. After the raw liquid is collected in the collecting tank, it flows to the switchable filter element through the discharge pipe, and is discharged through the lower flange pipe and the drain pipe after being filtered by the screen changing plate on the switchable filter element. The switchable filter element is provided with two staggered screen changing plates which are pushed by hydraulic cylinders respectively. Any screen changing plate can be pushed into the working station to filter the raw liquid, and the other screen changing plate can be in the non-working position to clean and replace the filter plate.

[0008] Preferably, the discharge pipe is provided with a valve which can control the flow of the discharge pipe by adjusting the switch.

[0009] Preferably, rectangular grooves located outside the rectangular slot are formed on both sides of the shell.

[0010] Preferably, a rectangular sealing plate for blocking the rectangular groove is fixedly connected to the outer side of the screen changing plate, a connecting block A is provided on the outer side of the rectangular sealing plate, and a connecting block B fixedly arranged at the end of the hydraulic cylinder is fixedly connected to the connecting block A by bolts.

[0011] The cooperation of the rectangular groove and the rectangular sealing plate can effectively seal the groove on the shell, facilitate the stable flow of the raw liquid, avoid leakage and overflow of the raw liquid, and improve production efficiency and product quality.

[0012] Preferably, a circular through hole B is provided on the screen changing plate, and a supporting ring is provided at the lower end of the circular through hole B for fixing the screen changing plate. A filter cylinder located in the circular through hole B is placed on the supporting ring, and an externally threaded pressing ring is connected to the internal thread of the circular through hole B for pressing and fixing the filter cylinder on the supporting ring. The externally threaded pressing ring can be installed on or removed from the screen changing plate by applying force to a handle rod fixed on the externally threaded pressing ring.

[0013] The design of the support ring and the external threaded pressure ring ensures the fixation of the filter cartridge in the circular through hole B, prevents the filter cartridge from shifting during operation, and facilitates the disassembly and replacement of the filter cartridge.

[0014] Preferably, after the external thread pressing ring is threadably connected to the screen changing plate, the upper surface of the external thread pressing ring is flush with the upper surface of the screen changing plate, so that the screen changing plate can be easily inserted into or pulled out of the rectangular slot.

[0015] The outer diameter of the filter cylinder is smaller than the diameter of the circular through hole B. The support ring is provided with a plurality of leakage holes arranged in an annular pattern at equal distances. The filter cylinder is designed as a concave groove structure. The concave groove helps to improve the flow distribution of the original liquid in the filter cylinder, making the filtration more uniform and further improving the filtration effect.

[0016] Preferably, a funnel-shaped liquid guide nozzle is provided in the upper flange tube, so as to facilitate the concentrated discharge of the original liquid in the center and facilitate the filtration and discharge of the original liquid.

[0017] Preferably, when the hydraulic cylinder pushes the screen changing plate to a non-working position, the screen changing plate blocks the rectangular slot and does not affect the normal filtering process.

[0018] Compared with the prior art, the technical effects and advantages of the utility model are:

[0019] The raw liquid collection device for wood vinegar production has the raw liquid flowing into the collection tank through the discharge pipe at the bottom of the collection tank. By opening the valve, the raw liquid flows from the collection tank through the discharge pipe to the switchable filter element. After the raw liquid enters the switchable filter element, the screen plate can be pushed by the hydraulic cylinder, and the filter cylinder with a concave groove structure is installed on the working station. The raw liquid passes through the filter cylinder, and impurities and solid particles are effectively filtered, thereby improving the quality and purity of the product. The filtered liquid flows out from the outer side of the filter cylinder through the leakage hole, or is filtered out from the bottom of the filter cylinder. The discharged liquid is discharged from the system through the lower flange pipe and the drain pipe.

[0020] The screen changer can be cleaned and replaced in the non-working position. The hydraulic cylinder pushes the screen changer to the non-working position, while the other screen changer is pushed to the working position to keep the filtration going continuously. This can reduce downtime and improve production efficiency. When the filter cartridge needs to be replaced, the external threaded pressing ring that fixes the filter cartridge can be loosened and the filter cartridge can be removed or installed through the handle. This makes it easy to maintain and replace the filter cartridge, reducing maintenance costs and time.

[0021] The switchable filter element uses two screen changing plates, so that the filtration process can be carried out continuously, improving the filtration efficiency and production capacity. The design of the concave groove structure of the filter cylinder and the setting of the leakage hole make the filtration more uniform, which can effectively remove impurities and solid particles in the wood vinegar liquid and improve the quality and purity of the product. The hydraulic cylinder drives the switching of the screen changing plate, and the valve controls the flow of the discharge pipe, making the operation simple and convenient, reducing the difficulty of operation and the risk of error. The combination of the rectangular groove and the rectangular sealing plate on the outer shell, as well as the liquid guide nozzle in the upper flange pipe, ensure that the raw liquid flows stably to the switchable filter element to avoid leakage and impurities from entering the system again.

[0022] In general, this raw liquid collection device for wood vinegar production ensures the filtration quality and production efficiency of the raw liquid through efficient filtration and convenient operation, thereby improving the quality and purity of the product.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The following is combined with Figure 1-7 To further explain this application in detail,

[0033] The embodiment of the present application discloses a raw liquid collecting device for wood vinegar production, comprising a collecting tank 1 and a switchable filter element 3, wherein a discharge pipe 2 is provided at the bottom of the collecting tank 1; the switchable filter element 3 comprises a square structured shell 31, a circular through hole A32 opened at the center of the shell 31, two rectangular slots 33 opened on both sides of the shell 31 and connected to the circular through hole A32 and staggered in an upper and lower position, a screen changing plate 34 respectively plugged in with the two rectangular slots 33, and a hydraulic cylinder 35 respectively pushing the screen changing plate 34 to switch between a working station and a non-working station; a funnel-shaped liquid guiding nozzle 38 is provided in the upper flange tube 36, so as to facilitate the concentrated discharge of raw liquid in the center and facilitate the filtration and discharge of raw liquid, and an upper flange tube 36 and a lower flange tube 37 are respectively provided at the upper and lower ends of the shell 31, the upper flange tube 36 is flange-connected to the discharge pipe 2, and the lower flange tube 37 is flange-connected to the drain pipe 4.

[0034] The collecting tank 1 is used to collect the raw liquid in the wood vinegar. After the raw liquid is collected in the collecting tank 1, it flows to the switchable filter element 3 through the discharge pipe 2, and is filtered by the screen changing plate 34 on the switchable filter element 3 and discharged through the lower flange pipe 37 and the drain pipe 4. Two staggered screen changing plates 34 are arranged on the switchable filter element 3 and are pushed by hydraulic cylinders 35 respectively. Any screen changing plate 34 can be pushed into the working position to filter the raw liquid, and the other screen changing plate 34 can be in a non-working position to clean and replace the filter plate.

[0035] The screen changing plate 34 on the switchable filter element 3 can filter the raw liquid efficiently, ensuring that the impurities and solid particles in the wood vinegar are effectively removed, thereby improving the quality and purity of the product. Since two screen changing plates 34 are provided on the switchable filter element 3, they can be used in turn, one as a working station for filtering, and the other as a non-working station for cleaning and replacement. This can reduce downtime and production costs, and improve production efficiency. The hydraulic cylinder 35 can easily push the screen changing plate 34 to switch between the working station and the non-working station, and the operation is simple and convenient. The discharge pipe 2 at the bottom of the collection tank 1 is docked with the upper flange pipe 36, and the drain pipe 4 is docked with the lower flange pipe 37, which effectively ensures the stability and continuity of the raw liquid flowing to the switchable filter element 3, and avoids leakage and the re-entry of impurities.

[0036] The discharge pipe 2 is provided with a valve 5. The valve 5 can control the flow of the discharge pipe 2 by adjusting the switch, so that the flow of the raw liquid between the collection tank 1 and the switchable filter 3 can be adjusted as needed. This can avoid the flow being too large or too small to affect the production effect. The switch design of the valve 5 can make the operation more convenient, and the flow of the discharge pipe 2 can be opened or closed at any time as needed. This can conveniently control the flow direction and stop of the raw liquid.

[0037] Rectangular grooves 39 located outside the rectangular slots 33 are opened on both sides of the shell 31, and a rectangular sealing plate 310 for blocking the rectangular grooves 39 is fixedly connected to the outside of the screen changing plate 34. A connecting block A311 is provided on the outer side of the rectangular sealing plate 310, and a connecting block B312 fixedly arranged at the end of the hydraulic cylinder 35 is fixedly connected to the connecting block A311 by bolts 313.

[0038] The cooperation between the rectangular groove 39 and the rectangular sealing plate 310 can effectively block the groove on the shell 31, facilitate the stable flow of the raw liquid, avoid leakage and overflow of the raw liquid, and improve production efficiency and product quality.

[0039] A circular through hole B314 is provided on the screen changing plate 34, and a supporting ring 315 fixedly connected to the screen changing plate 34 is provided at the lower end of the circular through hole B314. A filter cylinder 316 located in the circular through hole B314 is placed on the supporting ring 315. The internal thread of the circular through hole B314 is connected to an external thread pressing ring 317 which presses and fixes the filter cylinder 316 on the supporting ring 315. The external thread pressing ring 317 is installed on or removed from the screen changing plate 34 by applying force to a handle rod 318 fixed on the external thread pressing ring 317. When the hydraulic cylinder 35 pushes the screen changing plate 34 to a non-working position, the screen changing plate 34 blocks the rectangular slot 33 without affecting the normal filtering process.

[0040] The design of the support ring 315 and the external threaded pressing ring 317 ensures that the filter cartridge 316 is fixed in the circular through hole B314, and prevents the filter cartridge 316 from shifting during operation;

[0041] The handle bar 318 is located at the inner side of both ends of the external thread pressing ring 317, which does not affect the flow direction of the raw liquid and facilitates the disassembly of the external thread pressing ring 317, maintaining the compactness of the structure of the entire switchable filter element 3. The external thread pressing ring 317 can be disassembled by rotating it, which is convenient for the disassembly and replacement of the filter cartridge 316, and also convenient for the installation and fixation of the filter cartridge 316, which reduces downtime and improves production efficiency. The filter cartridge 316 can be replaced without special tools, reducing maintenance costs and time.

[0042] After the external thread pressing ring 317 is threadedly connected to the screen changing plate 34 , the upper surface of the external thread pressing ring 317 is flush with the upper surface of the screen changing plate 34 , which facilitates the screen changing plate 34 to be inserted into the rectangular slot 33 or pulled out from the rectangular slot 33 .

[0043] The outer diameter of the filter cylinder 316 is smaller than the diameter of the circular through hole B314. The support ring 315 is provided with a plurality of leakage holes 319 arranged in a circular pattern at equal distances. The filter cylinder 316 is designed as a concave groove structure. The concave groove helps to improve the flow distribution of the raw liquid in the filter cylinder 316, making the filtration more uniform and further improving the filtration effect. Due to the concave groove structure of the filter cylinder 316, solid particles are more difficult to clog on the filter because the flow path is longer and the particles are more easily intercepted in the groove. Compared with the flat filter of traditional technology, a larger filtration area is provided. The raw liquid can flow out from the outer side of the filter cylinder 316 through the leakage holes 319 or be filtered out from the bottom of the filter cylinder 316, which can improve the filtration effect and efficiency.

[0044] The raw liquid in the wood vinegar is collected in the collection tank 1 during the production process, and the raw liquid flows to the switchable filter element 3 through the discharge pipe 2 at the bottom of the collection tank 1. After the raw liquid enters the switchable filter element 3, the hydraulic cylinder 35 is pushed as needed to push one of the screen changing plates 34 into the working station to start the filtering operation. The raw liquid is filtered through the filter cylinder 316 on the screen changing plate 34 through the circular through hole A32 and the rectangular slot 33 connected thereto. The concave groove structure of the filter cylinder 316 and the setting of the leakage hole 319 can improve the filtering effect and efficiency. The filtered liquid flows out from the outer side or bottom of the filter cylinder 316 and is discharged through the lower flange pipe 37 and the drain pipe 4.

[0045] During the filtering process, the hydraulic cylinder 35 can push the screen changing plate 34 to switch between the working position and the non-working position. After completing a working cycle, the screen changing plate 34 in the working position can be pushed back to the non-working position, and then the screen changing plate 34 in the non-working position can be pushed into the working position for the next round of filtering operation. When the filter cartridge 316 needs to be replaced, the handle rod 318 can be used to apply force to the external thread pressing ring 317 to remove or install the external thread pressing ring 317, so as to facilitate the replacement of the filter cartridge 316.

[0046] In general, the device can collect raw liquid, filter raw liquid and discharge filtered liquid, and maintain continuous filtering operation by switching the screen plate 34 and replacing the filter cylinder 316. This can improve production efficiency and product quality.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
