Description

Technical Field

[0001] The present application relates to the technical field of beverage filtration, and specifically discloses a real-time back-flushing filtration device. Background Art

[0002] During the processing of wine and beverages, there may be some suspended matter and sediments in the wine and beverages, such as raw material residues, proteins, polysaccharides, minerals, etc. These substances will affect the transparency and taste of the product. They can be removed by filtering to improve the appearance quality and taste of the product. For example, during the fermentation process of wine, impurities such as lees and yeast metabolites will be produced. Filtration can remove these impurities and make the wine clearer and more transparent. Moreover, in the production process, filtration is a prerequisite for subsequent processing procedures. For example, in the blending and deployment process of wine, the original wine needs to be filtered first to remove impurities and insoluble substances, and then blending and deployment are carried out to ensure the quality and consistency of the product.

[0003] The filtration device is an indispensable equipment in the processing of wine and beverages. Its main function is to remove impurities, microorganisms and other unnecessary components in beverages and wines. According to its different principles and filtration functions, it can be divided into microporous membrane core filters, plate and frame filters and bag filters.

[0004] However, during the use of the existing filtering device, after the filter element has been filtering for a long time, suspended matter and sediment are easy to adhere and accumulate on the surface of the filter element, and a filter cake layer will be formed on the surface of the filter hole, resulting in increased filtration resistance and reduced filtration efficiency, which seriously affects the normal filtration effect. The current effective way to deal with this is to remove the filter element when the filter device is shut down, and then backflush the filter element with gas or liquid. This method requires the filter device to be shut down, affecting the normal production process, and requires the filter element to be disassembled. The overall process is complicated and cumbersome, and frequent disassembly and installation of the filter element will also cause certain damage to its installation components and connecting components, thereby affecting the service life of the filter element. Therefore, in view of this, the inventor provides a real-time backflush filter device to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that in a traditional filtering device, the filter element needs to be disassembled for back-blowing cleaning, the cleaning is complicated and tedious and affects the production process.

[0006] In order to achieve the above object, the basic scheme of the present invention provides a real-time backwash filtering device, comprising:

[0007] frame;

[0008] The filter chamber is arranged on the frame, the side walls of the filter chamber are respectively provided with a feed pipe and a slag discharge trough, and the bottom of the filter chamber is provided with a discharge pipe;

[0009] A filter element rotatably connected to the filter chamber and a driving mechanism for driving the filter element to rotate;

[0010] A cleaning groove arranged in the filter bin and capable of contacting the surface of the filter element to form a closed environment, and a sliding plate slidably and sealingly connected in the cleaning groove, wherein a plurality of first springs are arranged between the sliding plate and the cleaning groove;

[0011] a collection tank located within the filter element, directly below the cleaning tank and connected to the slag discharge tank;

[0012] During the rotation of the filter element, the filter element presses the sliding plate to compress the first spring, and when a sealed environment is formed between the filter element and the cleaning tank, the elastic potential energy of the first spring drives the sliding plate to move toward the filter element.

[0013] The principles and effects of this basic solution are:

[0014] The present invention utilizes a driving mechanism to drive the filter element to rotate to avoid the continuous accumulation of suspended matter and sediment on one surface of the filter element, and at the same time utilizes the reciprocating squeezing of the sliding plate and then the first spring during the rotation of the filter element, and cooperates with the elastic potential energy of the first spring to release the sliding plate, so that when the sliding plate moves toward the filter element, the air is squeezed through the filter element to achieve the effect of real-time backblowing of the filter element, and the backblowing form is adopted, so that the air in the filter bin can be circulated internally, avoiding the process of disinfection and purification required by external air backblowing; and by adopting real-time backblowing cleaning, the adhesion between the suspended matter and sediment and the filter element is smaller, and the required backblowing force is also smaller. The purpose of uninterrupted cleaning of the filter element can be achieved by continuously acting on the surface of the filter element with a smaller backblowing force. The present invention can ensure that the filter element always maintains good filtering performance, thereby ensuring the quality of the product and the stability of production, and solves the problem that in traditional filtering devices, the filter element needs to be disassembled for backblowing cleaning, and the cleaning is complicated and cumbersome and affects the production process.

[0015] Furthermore, the filter element includes a plurality of filter plates connected in sequence, the cross section of the filter element is a regular polygon, and the end of the cleaning groove is provided with an arc surface adapted to the circumscribed circle of the cross section of the filter element. Through this arrangement, when the regular polygon filter element rotates, the end foot of the filter element can contact the end of the sliding plate or the cleaning groove, and when the end foot of the filter element contacts the sliding plate, the sliding plate can be squeezed, and when the end foot of the filter element is connected to the end of the cleaning groove, the contact surface of the filter element and the cleaning groove can form a relatively closed connection relationship, avoiding air from directly flowing out from the end of the filter element and the cleaning groove, and after the end foot of the filter element is disconnected from the end of the cleaning groove, a gap is formed between the filter element and the end of the cleaning groove to allow air to enter between the sliding plate and the filter element.

[0016] Furthermore, the end feet of the adjacent filter plates are provided with transition surfaces adapted to the arc surface, so as to improve the sealing performance between the filter plate and the end of the cleaning tank.

[0017] Furthermore, the driving mechanism comprises:

[0018] A power part, arranged on the frame;

[0019] A main shaft, rotatably connected to the filter bin and driven to rotate by the power member;

[0020] A rotating disk, rotatably connected to the inner wall of the filter bin away from the feed pipe, and respectively connected to the outer wall of the main shaft and one end of the filter element;

[0021] The rotating ring is rotatably connected to the inner wall of the filter bin close to the feed pipe and is connected to the other side of the filter element.

[0022] Providing a rotating disk and a rotating ring to connect the filter element can improve the sealing between the filter element and the filter bin, and at the same time provide an avoidance space for the installation of structures such as a collecting tank, a slag discharge tank, and a feed pipe.

[0023] Furthermore, the outer diameter of the rotating ring is larger than the circumscribed circle of the cross section of the filter element, and the inner diameter of the rotating ring is smaller than the inscribed circle of the cross section of the filter element, so as to avoid leakage of wine and beverages between the ends of the filter element during the rotation of the filter element, and further improve the sealing performance between the filter element and the filter chamber.

[0024] Furthermore, it also includes:

[0025] A snap-fit ​​mechanism capable of snapping the sliding plate to the side wall of the cleaning tank;

[0026] A release mechanism for releasing the sliding plate engaged to the side wall of the cleaning tank.

[0027] A locking mechanism and a releasing mechanism are provided to store the elastic potential energy of the first spring so that the sliding plate is locked to the side wall of the cleaning groove after squeezing the first spring. Even if the filter element is out of contact with the sliding plate, the sliding plate will not be reset. When a closed space is formed between the filter element and the cleaning groove, the releasing mechanism releases the sliding plate, thereby improving the back-blowing effect on the surface of the filter element.

[0028] Furthermore, the engaging mechanism includes a block slidably connected to the side wall of the cleaning groove and a second spring driving the block to reset, and one end of the block is provided with an inclined surface that can extend into the cleaning groove, and when the sliding plate slides along the inclined surface, the second spring is squeezed. By providing the inclined surface, when the sliding plate is pushed by the filter element, the block is squeezed, and then the second spring is squeezed, and after the sliding plate is out of contact with the inclined surface, the elastic potential energy of the second spring drives the block to reset, so that the sliding plate and the side wall of one end of the block located in the cleaning groove are mutually engaged.

[0029] Furthermore, the clamping mechanism further comprises a guide rod connected to the clamping block, a retaining ring arranged on the side wall of the guide rod and a connecting plate arranged in the filter bin, and the second spring is arranged between the guide rod and the retaining ring. The guide rod, retaining ring and connecting plate are arranged so as to facilitate the use of the elastic potential energy of the second spring to drive the clamping block to reset.

[0030] Furthermore, a sleeve is provided on one side of the connecting plate close to the guide rod, and one end of the guide rod is slidably connected in the sleeve. The sleeve cooperates with the guide rod to limit and guide the sliding of the block.

[0031] Furthermore, the release mechanism comprises a push rod slidably connected to the cleaning groove, a push block provided at the top of the push rod and adapted to the inclined surface, and a push head provided at the bottom of the push rod and capable of being squeezed by the filter element. By providing the push rod, the push block and the push head, when the transition surface of the filter element moves to the side wall of the cleaning groove, the transition surface of the filter element squeezes the push head, causing the push rod to move, thereby causing the push block to push the inclined surface of the block, thereby releasing the sliding plate.

[0044] The filter bin 4 is welded to the frame 1 by steel plates, a cover plate 5 is provided on the top of the filter bin 4 for sealing, a slag discharge trough 7 located above the axis and a feed pipe 8 located below the axis are provided on the left side wall of the filter bin 4, and a discharge pipe 6 is connected to the bottom of the filter bin 4 through multiple branch pipes.

[0045] like Figure 3 and Figure 4 As shown, the filter element 9 is composed of six filter plates connected in sequence, so that the cross-section of the filter element 9 is a regular hexagon, and the end feet of the adjacent filter plates are provided with a transition surface adapted to the circumscribed circle of the regular hexagon, the feed pipe 8 and the slag discharge trough 7 are connected to the interior of the filter element 9, and a collecting trough connected to the slag discharge trough 7 is provided between the left and right sides of the filter bin 4.

[0046] A sealing plate 11 is provided at the top of the filter bin 4, and two vertical plates 12 are symmetrically provided below the sealing plate 11. A cleaning groove is formed between the two vertical plates 12, the sealing plate 11 and the surface of the filter element. The cleaning groove is located directly above the collecting groove. An arc surface that matches the circumscribed circle of the cross section of the filter element 9 is provided at the bottom of the two vertical plates 12, and the arc surface is also matched with the filter surface at the connection between adjacent filter plates.

[0047] A sliding plate 13 is connected by a sliding seal in the cleaning groove, and a plurality of first springs 14 are arranged between the sliding plate 13 and the sealing plate 11.

[0050] like Figure 3 and 5As shown, during the rotation of the filter element 9, the transition surface of the filter element 9 squeezes the sliding plate 13, causing the sliding plate 13 to move upward. During this process, the sliding plate 13 squeezes the block 22, thereby squeezing the second spring 23. After the sliding plate 13 is out of contact with the inclined surface, the elastic potential energy of the second spring 23 drives the block 22 to reset, so that the sliding plate 13 and the side wall of one end of the block 22 located in the cleaning groove are engaged with each other; the filter element 9 continues to move, resulting in the transition surface of the filter element 9 being out of contact with the sliding plate 13, but the sliding plate 13 remains stationary due to the action of the block 22 until the transition surface of the filter element 9 rotates to the bottom of the vertical plate 12 and squeezes the push head 17, causing the push rod 16 to move upward, thereby causing the push block to push the inclined surface of the block 22, thereby releasing the sliding plate 13, and the sliding plate 13 moves downward quickly, squeezing the air to pass through the filter element 9, so as to achieve the effect of real-time backblowing of the filter element 9.

The power member 2 adopts a stepping motor, which drives the main shaft 10 to rotate intermittently at an angle of 60° through the reducer 3. The two ends of the main shaft 10 are rotatably connected to the two sides of the filter chamber 4 respectively. The rotating disk 24 is rotatably connected to the inner wall of the filter chamber 4 away from the feed pipe 8, and is respectively connected to the outer wall of the main shaft 10 and one end of the filter element 9; the rotating ring 25 is rotatably connected to the inner wall of the filter chamber 4 close to the feed pipe 8, and is connected to the other side of the filter element 9.

The rotating disk 24 and the rotating ring 25 are both embedded in the side wall of the filter chamber 4.

[0052] In the present embodiment, the filter element 9 is driven to rotate by the driving mechanism, which can not only prevent the suspended matter and the sediment from being continuously accumulated on one surface of the filter element 9, but also prevent the suspended matter and the sediment from being accumulated; at the same time, the sliding plate 13 is reciprocated and squeezed during the rotation of the filter element 9, and then the first spring 14 is squeezed, and the locking mechanism is used for locking and the releasing mechanism is used for releasing, and the sliding plate 13 is released with the elastic potential energy of the first spring 14, so that when the sliding plate 13 moves toward the filter element 9, the air is squeezed to pass through the filter element 9, so as to achieve the effect of real-time backblowing of the filter element 9, and the backblowing form is used to make the filter element 9 The air in the filter bin 4 can be circulated internally, avoiding the need for disinfection and purification processes using external air backblowing; and by using real-time backblowing cleaning, the adhesion between suspended matter and sediment and the filter element 9 is relatively small, and the required backblowing force is also smaller. The purpose of uninterrupted cleaning of the filter element 9 can be achieved by continuously acting on the surface of the filter element 9 with a smaller backblowing force. The present invention can ensure that the filter element 9 always maintains good filtering performance, thereby ensuring product quality and production stability, and solves the problem that in traditional filtering devices, the filter element 9 needs to be disassembled for backblowing cleaning, and the cleaning is complicated and cumbersome and affects the production process.
