Description

Technical Field

[0001] The invention relates to a filtering structure and a glutinous rice slurry filter press, belonging to the technical field of glutinous rice processing. Background Art

[0002] In the processing of glutinous rice slurry, traditional filtration structures and filter presses have many shortcomings. On the one hand, the filter bags often lack sufficient support, which makes it easy for the solid particles to completely adhere to the substrate during the filtration process, resulting in poor slurry flow and greatly reduced filtration efficiency. On the other hand, the communication method between adjacent retention chambers is not reliable enough, which easily leads to slurry mixing and filtration failure. In addition, traditional filter presses often require manual cleaning of solid residues adhering to the filter bags, which is not only inefficient but also increases labor maintenance costs. In order to solve the above problems, a filtration structure and a glutinous rice slurry filter press are proposed. Summary of the invention

[0003] The object of the present invention is to provide a filtering structure and a glutinous rice slurry filter press to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a filtering structure and a glutinous rice slurry filter press, comprising a plurality of box-type filter plates arranged side by side, wherein the box-type filter plates each comprise a frame, a support frame and a filter bag, wherein the support frame is arranged inside the frame, and the filter bag is sleeved on the support frame, wherein the interior of the filter bag is a flow cavity for the flow of glutinous rice slurry, and between the filter bags on two adjacent box-type filter plates is a retention cavity for the retention of glutinous rice solid particles, and each retention cavity is connected through a communicating vessel, and the support frame comprises:

[0005] A frame, the frame being inserted into the interior of the frame;

[0006] A base plate, which is fixed inside the frame, supports the filter bag and divides the flow chamber into two;

[0007] A first channel, the first channel being arranged at a connection between the base plate and the lower end of the frame;

[0008] When the glutinous rice slurry is diverted to each retention chamber through the communicating vessel, the solid particles of the glutinous rice slurry are retained in the retention chamber, and the slurry in the glutinous rice slurry passes through the filter bag and enters the flow chamber;

[0009] When the slurry is filtered by the filter bag into the flow chamber, the slurry is discharged from the first channel;

[0010] Wherein, a plurality of pads for placing filter bags and attaching them to the substrate are distributed on both sides of the substrate, and each pad is arranged horizontally on the substrate.

[0011] Preferably, the pad is rotatably connected to the base plate via a driving assembly, and the driving assembly comprises:

[0012] Gears fixed at both ends of the pad;

[0013] A sliding rod, wherein the sliding rod is slidably connected to both sides of the support frame, the sliding rod is meshed with the gear through teeth, and the upper end of the sliding rod extends upward to the outside of the support frame and is connected to a moving rod;

[0014] When the moving rod moves upward with the sliding rod, the sliding rod drives the gear to rotate, so that the lower side of the pad rotates toward the base plate;

[0015] When the movable rod moves downward with the sliding rod, the sliding rod drives the gear to rotate, causing the lower side of the pad to rotate away from the base plate.

[0016] Preferably, the pad gradually becomes thinner from top to bottom.

[0017] Preferably, the surface of each pad is provided with raised ribs spaced apart from each other, and a liquid flow channel is provided between two adjacent ribs.

[0018] Preferably, a second channel is provided at the upper end of the frame, and a cleaning pipe is provided at the upper end of the frame, the cleaning pipe is connected to the flow cavity on the same support frame through the second channel, and a water inlet for injecting cleaning liquid into the cleaning pipe is provided on the cleaning pipe.

[0019] Preferably, the communicating vessel comprises a hollow stud and a nut, the hollow stud comprises an end head and a threaded column, the end head is fixed to the end of the threaded column, and the end of the threaded column away from the end head penetrates the side walls of the filter bag and the base plate and is engaged with the nut.

[0020] Preferably, a fixing bar is provided at the upper port portion of the filter bag, and the fixing bar is fixedly connected to the side wall of the frame by screws.

[0021] A glutinous rice slurry filter press comprises a frame and the above-mentioned filtering structure.

[0022] Compared with existing technologies:

[0023] The present invention not only provides a solid support for the filter bag through the design of the substrate inside the frame, but also divides the flow cavity into two areas, thereby increasing the filtration area and improving the filtration efficiency. The substrate and the first channel at the lower end of the frame guide the flow direction of the slurry, ensuring that the slurry can be smoothly discharged from the flow cavity, avoiding the reduction of the filtration effect caused by the retention of slurry. In addition, through the combination of the hollow stud and the nut, not only the reliable connection of adjacent retention cavities is achieved, but also the effective separation of the flow cavity and the retention cavity is ensured by pressing the filter bag, avoiding the filtration failure caused by the mixing of slurries, and improving the stability and reliability of the entire filtration system.

[0024] In the process of filter pressing, the backing plate of the present invention can adjust its relative position with the substrate and the filter bag through the precise control of the driving component. When the glutinous rice slurry passes through the filter bag and enters the flow cavity, the backing plate not only provides the necessary support for the filter bag, preventing it from completely fitting the substrate due to the accumulation of solid particles, but also ensures the smoothness of the slurry flow and improves the filter pressing efficiency. At the same time, the liquid flow channel designed on the backing plate further ensures the free flow of the slurry in the flow cavity, avoiding the decrease in filtration efficiency due to the closure of the flow channel. When the filter pressing is completed, the backing plate can automatically unfold and scrape off the solid residue adhered to the filter bag under the drive of the driving component, which greatly simplifies the cleaning process, improves the cleaning efficiency, and reduces the labor maintenance cost.

[0049] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0050] Embodiment 1

[0051] like Figure 1-Figure 11As shown, in this embodiment, a filtering structure and a glutinous rice slurry filter press are provided, including a frame 8 and a plurality of box-type filter plates arranged side by side, the plurality of box-type filter plates are arranged on the frame 8, a left vertical plate 801, a right vertical plate 802 and two cross beams 803 are arranged on the frame 8, the two cross beams 803 are transversely fixedly connected between the left vertical plate 801 and the right vertical plate 802, the frame 1 slides on the cross beam 803 through a slide 104, the slides 104 are respectively fixed on both sides of the frame 1, and an oil cylinder for tightening the plurality of box-type filter plates is arranged on the left vertical plate 801 11; The box-type filter plates all include a frame 1, a support frame 2 and a filter bag 3. The support frame 2 is arranged inside the frame 1, and the filter bag 3 is sleeved on the support frame 2. When the filter bag 3 is sleeved on the support frame 2, the filter bag 3 is in a relaxed state. A fixing strip 301 is arranged on the upper end of the filter bag 3, and the fixing strip 301 is fixedly connected to the side wall of the frame 201 by screws. The interior of the filter bag 3 is a flow cavity for the flow of glutinous rice slurry, and the space between the filter bags 3 on two adjacent box-type filter plates is a retention cavity for the retention of glutinous rice solid particles. A useful The grouting pipe 10 is used to inject the glutinous rice slurry into the retention cavity. Each retention cavity is connected through the communicating vessel 4. The support frame 2 includes a frame 201. The frame 201 is plugged into the inside of the frame 1. The frame 1 is a U-shaped structure with an opening facing upward. Slots 101 are provided on both sides of the frame 1. Insert blocks 2011 are provided on both sides of the frame 201. When installing, the bottom of the frame 201 with the filter bag 3 is aligned with the opening of the frame 1. At this time, the lower end of the insert block 2011 is aligned with the upper end of the slot 101, and then the frame 201 is inserted from the opening of the frame 1. At this time, the plug block 2011 is inserted into the inside of the slot 101, and the lower end of the frame 201 is against the lower end side wall of the frame 1, and the frame 201 is installed. At this time, the plug block 2011 and the groove wall of the slot 101 clamp the two sides of the filter bag 3, and the lower end of the frame 201 and the lower end of the frame 1 clamp the bottom wall of the filter bag 3; a base plate 202 is fixed inside the frame 201, and the base plate 202 supports the filter bag 3 and divides the flow chamber into two; a first channel 203 is provided at the connection between the base plate 202 and the lower end of the frame 201.

[0052] When the glutinous rice slurry is diverted to each retention chamber through the communicating vessel 4, the solid particles of the glutinous rice slurry are retained in the retention chamber, and the slurry in the glutinous rice slurry passes through the filter bag 3 and enters the flow chamber;

[0053] When the slurry is filtered by the filter bag 3 into the flow chamber, the slurry is discharged from the first channel 203. Figure 2 and Figure 3 As shown, a guide groove 102 is provided on the frame 1, and a drainage pipe 103 is provided on one side of the frame 1. When the frame 201 is installed on the frame 1, the first channel 203 is located above the guide groove 102, and the first channel 203 is connected with the guide groove 102. The slurry in the flow cavity can flow from the first channel 203 to the guide groove 102 and be discharged from the drainage pipe 103.

[0054] There are multiple pads 5 on both sides of the base plate 202 for placing the filter bags 3 and attaching them to the base plate 202 , and each pad 5 is arranged horizontally on the base plate 202 .

[0055] The communicating vessel 4 includes a hollow stud 401 and a nut 402. The hollow stud 401 includes an end 4011 and a threaded column 4012. The end 4011 is fixed to the end of the threaded column 4012. The end of the threaded column 4012 away from the end 4011 penetrates the side wall of the filter bag 3 and the base plate 202 and is meshed with the nut 402.

[0056] like Figure 3 As shown, through holes are provided at corresponding positions of the filter bag 3 and the base plate 202. After the filter bag 3 is put on the support frame 2, the through holes on the filter bag 3 are aligned with the through holes on the base plate 202. Then, the threaded column 4012 is inserted into the through hole, and the end 4011 presses one side of the filter bag 3 (the outline of the through hole) against the side wall of the base plate 202. Then, the nut 402 is screwed onto the threaded column 4012. The nut 402 can press the other side of the filter bag 3 against the side wall of the base plate 202. In this way, the flow chamber is separated from the retention chamber. At the same time, the two adjacent retention chambers can be connected using the hollow stud 401.

[0057] Embodiment 2

[0058] like Figure 7-Figure 11 As shown, on the basis of the first embodiment, in this embodiment, the pad 5 is rotatably connected to the base plate 202 through a driving assembly 6, and the driving assembly 6 includes gears 601 fixed at both ends of the pad 5; sliding rods 602 are slidably connected to both sides of the support frame 2, and the sliding rods 602 are meshed with the gears 601 through teeth, and the upper ends of the sliding rods 602 extend upward to the outside of the support frame 2 and are connected to a moving rod 603, and the sliding rods 602 are slidably sleeved on the moving rods 603. When the frame 1 moves on the crossbeam 803, the upper ends of the sliding rods 602 are slidably sleeved on the moving rods 603, so that the position of the sliding rods 602 relative to the frame 1 can be adjusted. At the same time, it does not affect the normal driving of the sliding rods 603 to move the sliding rods 602. Electric push rods 9 for driving the moving rods 603 to slide are fixed on the left vertical plate 801 and the right vertical plate 802, and one moving rod 603 is controlled to move by two electric push rods 9, that is, Fig.11 As shown, both ends of a movable rod 603 are respectively connected to the output shaft of an electric push rod 9;

[0059] When the movable rod 603 moves upward with the sliding rod 602, the sliding rod 602 drives the gear 601 to rotate, so that the lower side of the pad 5 rotates toward the base plate 202;

[0060] When the movable rod 603 moves downward with the sliding rod 602 , the sliding rod 602 drives the gear 601 to rotate, so that the lower side of the pad 5 rotates away from the base plate 202 .

[0061] like Fig. 9 As shown, on the same support frame 2, the gears 601 on the pads 5 on the same side of the base plate 202 are located on the same side of the sliding rod 602, and the pads 5 on different sides of the base plate 202 are symmetrically arranged, and their gears 601 are respectively located on both sides of the sliding rod 602, so that when the sliding rod 602 slides, the pads 5 on the same side of the base plate 202 slide synchronously, and the pads 5 on different sides slide symmetrically and synchronously;

[0062] like Figure 8 As shown, the pad 5 is attached to the substrate 202, and the glutinous rice slurry is in the state of being filtered, and the filtering process is as follows:

[0063] When multiple box-type filter plates are tightly fitted together and then the glutinous rice slurry is introduced into each retention chamber, the solid particles of the glutinous rice slurry are retained in the retention chamber, and the slurry in the glutinous rice slurry passes through the filter bag 3 and enters the flow chamber. At this time, the slurry flows downward along the flow chamber, and finally the slurry is discharged from the first channel 203. As the glutinous rice slurry is continuously introduced into the retention chamber, the solid particles in the retention chamber continue to increase, and the solid particles will support the filter bag 3, causing the filter bag 3 to move toward the substrate 202 and finally fit on the substrate 202. Since a pad 5 is provided between the substrate 202 and the filter bag 3, there is always a gap between the substrate 202 and the filter bag 3 for the slurry to flow, so as to ensure the smooth flow of the slurry in the flow chamber and improve the filtration efficiency.

[0064] like Figure 7 As shown, after a plurality of box-type filter plates are separated, the filter bags 3 on two adjacent box-type filter plates are separated, causing the retention chamber to open. In this state, the pad 5 is reciprocated to make the pad 5 continuously expand. When the pad 5 is rotated and expanded, the lower end of the pad 5 props up the filter bag 3 away from the base plate 202. During the propping-up process, the lower end of the pad 5 slides on the side wall of the filter bag 3, performing a scraping operation. The solid residue (composed of fixed particles) adhered to the filter bag 3 can be quickly scraped off, thereby improving the efficiency of cleaning the solid residue.

[0065] The thickness of the pad 5 gradually decreases from top to bottom. The surface of each pad 5 is provided with raised ribs 501 at intervals. A liquid flow channel is provided between two adjacent ribs 501. When the filter bag 3 is squeezed on the base plate 202 by solid slag, the pad 5 is placed between the filter bag 3 and the base plate 202. The pad 5 is provided with a liquid flow channel formed by the ribs 501. The slurry passing through the filter bag 3 can flow downward along the liquid flow channel. In this way, the liquid flow cavity is prevented from being completely closed, and the flow of the slurry in the liquid flow cavity is ensured.

[0066] The design of the pad 5 gradually becoming thinner from top to bottom and the raised ribs 501 on the surface not only enhance the structural strength of the pad 5 but also optimize the flow path of the slurry.

[0067] Embodiment 3

[0068] like Figure 1-Figure 11 As shown, on the basis of the second embodiment, in this embodiment, a second channel 204 is provided at the upper end of the frame 201, and a cleaning pipe 7 is provided at the upper end of the frame 201. The cleaning pipe 7 is connected to the flow cavity on the same support frame 2 through the second channel 204. A water inlet 701 for injecting cleaning liquid into the cleaning pipe 7 is provided on the cleaning pipe 7. A hose is connected to the water inlet 701, and one end of the hose is connected to a water pump. When the water pump is started, the hose injects cleaning liquid into the cleaning pipe 7 through the water inlet 701, and then the cleaning liquid in the cleaning pipe 7 enters the flow cavity through the second channel 204. While the cleaning liquid is injected, the pad 5 is driven to circulate and expand. The cleaning liquid is guided by the pad 5 to improve the backwashing efficiency of the cleaning liquid on the filter bag 3, so that the solid residue adhering to the surface of the filter bag 3 can be quickly cleaned off.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
