Description

Technical Field

[0001] This application relates to the technical field of solid-liquid separation equipment, and particularly to a plate and frame filter press equipment. Background Art

[0002] As a widely used solid-liquid separation technology, the core mechanism of plate and frame filtration is to apply pressure on one side of the filter medium through mechanical force to achieve efficient solid-liquid separation. During filtration, first, a uniform pressure is applied to the filter mechanism through a hydraulic system or a mechanical clamping device to ensure that all components are closely fitted, maintaining the tightness of the filtration chamber and preventing liquid leakage. Subsequently, the feed pump is started, and the feed valve is slowly adjusted to allow the solid-liquid mixture to be treated to enter the filtration chamber under gradually increasing pressure. During this process, the liquid smoothly passes through the filter cloth and enters the channels between the filter plates, while the solids are effectively intercepted by the filter cloth and gradually accumulate into a filter cake. When the liquid discharge volume significantly decreases or almost stops, it indicates that the filter cake has been completely formed. At this time, the feed needs to be paused and the discharge is ready to be carried out.

[0003] Currently, the filter cake discharging method mainly relies on the plate pulling mechanism to separate the filter plates one by one, and then the shaking mechanism is used to shake each separated filter plate individually to promote the shedding of the filter cake.

Detailed Description of the Embodiment

[0018] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0019] The plate and frame filter press device of the embodiment of the present application will be described below in conjunction with the accompanying drawings.

[0020] As Figures 1 to 5 shown, the plate and frame filter press device of the embodiment of the present application may include two support plates 1, a plurality of filter plates 2, a pressing component 3, two separation components 4, two auxiliary blanking components 5, and a cleaning component 6.

[0021] Among them, a plurality of filter plates 2 are suspended between two support plates 1, and a filtering chamber is formed between two adjacent filter plates 2. A water inlet pipe 12 is installed on one support plate 1, and the water inlet pipe 12 communicates with the filtering chamber.

[0022] It should be noted that the filter plate 2 described in this embodiment is a closed filter plate. Fish-tail grooves are provided around the filter plate 2. There are two fish-tail grooves. The outer fish-tail groove is used to install a sealing strip, and the inner fish-tail groove is used to fix the filter cloth. Through holes are provided at the corner positions of the filter plate 2. After the filter plate 2 is pressed, the through holes can form a cleaning channel. It can be understood that the specific structure of the filter plate 2 is common knowledge in the art and will not be elaborated in this application.

[0023] Furthermore, a liquid pump is connected in communication with the water inlet pipe 12. The liquid pump is connected to the wastewater to be treated. Through the liquid pump, the wastewater to be treated can be conveyed to the water inlet pipe 12 and enter the filtering chamber through the water inlet pipe 12.

[0024] Connecting plates 10 are respectively provided on two opposite side walls of each filter plate 2. Bearing rods 11 are provided on both sides of the filter plate 2. The connecting plates 10 are placed on the bearing rods 11. The pressing assembly 3 is provided on one side of the filter plate 2, and the pressing assembly 3 is installed on the other support plate 1.

[0025] It should be noted that a groove matching the bearing rod 11 is provided on the lower surface of the connecting plate 10. The provision of the groove can increase the contact area between the bearing rod 11 and the bearing rod 11, improving the supporting effect on the filter plate 2.

[0026] Furthermore, the pressing assembly 3 can apply a certain pressure to the filter plate 2, so that a plurality of filter plates 2 can be closely attached to form a closed filtering chamber.

[0027] Support frames 13 are respectively provided on both sides of the filter plate 2. Two separating components 4 are respectively connected to the corresponding support frames 13. The separating component 4 includes a ball screw pair 40 and a connecting component 41. Among them, a chute 130 is formed on the upper surface of the support frame 13. The ball screw pair 40 is arranged in the chute 130, and the two ball screw pairs 40 are connected by a first transmission component 9. The connecting component 41 is respectively connected to the ball screw pair 40 and the connecting plate 10.

[0028] It should be noted that the separating component 4 described in this embodiment can quickly separate a plurality of filter plates 2, facilitating the dropping of the filter cake between two adjacent filter plates 2.

[0029] Furthermore, the first transmission component 9 may include two first sprockets 90 and a first chain 91. Among them, the two first sprockets 90 are respectively arranged on the corresponding first ball screws 400, and the two first sprockets 90 are connected by the first chain 91 in a transmission manner.

[0030] In an embodiment of the present application, after the ball screw pair 40 is started, with the cooperation of the connecting component 41, a plurality of filter plates 2 can be quickly separated, thereby facilitating the discharging of the filter cake.

[0031] Two auxiliary discharging components 5 are symmetrically arranged on both sides of the filter plate 2, and the auxiliary discharging component 5 is located below the connecting plate 10.

[0032] In an embodiment of the present application, the auxiliary discharging component 5 can drive the filter plate 2 to vibrate, thereby accelerating the discharging speed of the filter cake.

[0033] A collecting groove 14 is provided at the bottom of the filter plate 2. The cleaning component 6 is rotatably arranged inside the collecting groove 14, and the cleaning component 6 is connected to the auxiliary discharging component 5 through a second transmission component 8. Drain pipes 15 are respectively arranged on both sides of each filter plate 2, and a water tank 16 is installed below the drain pipes 15.

[0034] It should be noted that one side wall of the collecting groove 14 described in this embodiment is provided with an opening. The filter cake falling from the filter plate 2 will directly fall into the collecting groove 14. When the cleaning component 6 is started, the filter cake inside the collecting groove 14 can be pushed towards the opening direction.

[0035] Further, the drain pipe 15 is communicated with the groove on the filter plate. A guiding pipe is provided at the bottom of the water tank 16. The filtered water will enter the drain pipe 15 through the groove and be discharged from the drain pipe 15 into the water tank 16, and finally discharged from the guiding pipe. It can be understood that a control valve (not shown in the figure) can be provided on the drain pipe 15 to control the water flow rate discharged.

[0036] To further clarify the above embodiment, in an embodiment of the present application, as Figure 1 shown, the pressing component 3 may include a hydraulic rod 30 and a push plate 31. Among them, the hydraulic rod 30 is installed on the side wall of the support plate 1 through a support seat 17, and the push plate 31 is arranged at the output end of the hydraulic rod 30.

[0037] In an embodiment of the present application, when the hydraulic rod 30 is started, it can drive the push plate 31 to move towards the filter plate 2, thereby pressing a plurality of filter plates 2.

[0038] In an embodiment of the present application, as Figure 2 shown, the ball screw pair 40 includes a first ball screw 400 and a first slider 401. Among them, the first ball screw 400 is rotatably arranged in the sliding groove 130, and one end of the first ball screw 400 penetrates through the support plate 1, and the first slider 401 is sleeved on the first ball screw 400.

[0039] It should be noted that in this embodiment, the first ball screw 400 is connected to an external driving mechanism (such as a motor). The external driving mechanism can drive the first ball screw 400 to rotate, thereby driving the first slider 401 to move along the direction of the chute 130.

[0040] Further, as Figure 2 shown, the connecting component 41 includes a plurality of second sliders 410, a plurality of springs 411 and a plurality of first connecting rods 412. Among them, the plurality of second sliders 410 are respectively slidably connected to the chute 130, and one of the second sliders 410 is connected to the first slider 401. The plurality of springs 411 are respectively arranged on the corresponding second sliders 410, and the top ends of the springs 411 are connected to the connecting plate 10. Adjacent two second sliders 410 are connected by two first connecting rods 412, and one ends of the two first connecting rods 412 are respectively hinged to the corresponding second sliders 410, and the other ends of the two first connecting rods 412 are hinged to each other.

[0041] It should be noted that the first slider 401 is connected to the outermost second slider 410, and through holes are formed through each second slider 410, and the first ball screw 400 is arranged through the through holes, that is, the second slider 410 is sleeved on the first ball screw 400.

[0042] Further, every two first connecting rods 412 form a group, and each group of first connecting rods 412 is hinged into a "V"-shaped plate, and both ends of the "V"-shaped plate are respectively hinged to adjacent two second sliders 410, so as to connect the plurality of second sliders 410 to each other.

[0043] In an embodiment of the present application, as Figure 1 and Figure 4 shown, the auxiliary blanking component 5 includes a rotating shaft 50 and a plurality of cams 51. Among them, both ends of the rotating shaft 50 are respectively rotatably connected to two support plates 1, and the plurality of cams 51 are evenly distributed on the rotating shaft 50.

[0044] It should be noted that the cams 51 described in this embodiment are correspondingly arranged with the connecting plate 10. Refer to Figure 5 , when adjacent filter plates 2 are separated from each other, the plurality of cams 51 are respectively arranged below the corresponding connecting plate 10. At this time, the rotating shaft 50 is driven to rotate, the rotating shaft 50 drives the cams 51 to rotate, and the protrusions on the cams 51 will push the connecting plate 10 upward, and the springs 411 are stretched. At this time, the filter plate 2 moves upward. When the protrusions on the cams 51 rotate to be separated from the connecting plate 10, the springs 411 drive the connecting plate 10 to reset and drive the filter plate 2 to move downward. In this way, the connecting plate 10 and the filter plate 2 can be driven to vibrate to quickly shake off the filter cake.

[0045] Furthermore, when the two sets of cams 51 on the two rotating shafts 50 in the application contact or separate synchronously with the connecting plate 10, they can drive the filter plate 2 to shake up and down. When the two sets of cams 51 contact or separate asynchronously with the connecting plate 10, that is, when one set of cams 51 contacts the connecting plate 10 and the other set of cams 51 separates from the connecting plate 10, the filter plate 2 can be driven to swing left and right. The two methods can be selected according to actual needs, thereby effectively speeding up the speed and effect of unloading.

[0046] In one embodiment of the present application, Figure 5 As shown, the cleaning assembly 6 includes a second ball screw 60, a third slider 61 and a cleaning plate 62, wherein the two ends of the second ball screw 60 are rotatably connected to the two support plates 1 respectively, the third slider 61 is sleeved on the second ball screw 60, and the cleaning plate 62 is slidably set inside the collection tank 14, and the cleaning plate 62 is connected to the third slider 61.

[0047] It should be noted that the cleaning plate 62 is slidably connected to the collecting tank 14, and the cleaning plate 62 contacts the inner lower wall of the collecting tank 14. When the second ball screw 60 rotates, it can drive the third slider 61 to move along the axial direction of the second ball screw 60, thereby driving the cleaning plate 62 to move. The cleaning plate 62 can be used to remove the filter cake in the collecting tank 14.

[0048] Furthermore, if Figure 1 As shown, the second transmission assembly 8 includes a plurality of second gears 80 and a second toothed chain 81 , wherein the plurality of second gears 80 are respectively arranged on the second ball screw 60 and the rotating shaft 50 , and the plurality of second gears 80 are transmission-connected via the second toothed chain 81 .

[0049] In an embodiment of the present application, the number of the second gears 80 can be set to three. By cooperating with the second gears 80 and the second tooth chain 81, the second ball screw 60 and the rotating shaft 50 can rotate synchronously without adding additional driving equipment, thereby reducing the manufacturing cost of the present application.

[0050] In one embodiment of the present application, Figure 4 As shown, one of the support plates 1 is provided with two grooves 20 on one side adjacent to the filter plate 2 , and two second connecting rods 18 are hinged between the second sliding blocks 410 adjacent to the grooves 20 and the grooves 20 .

[0051] It should be noted that the second connecting rod 18 described in this embodiment has the same structure as the first connecting rod 412. The two second connecting rods 18 are hinged to form a "V"-shaped plate, and the two ends of the "V"-shaped plate are hinged to the adjacent second slider 410 and groove 20 respectively.

[0052] Specifically, when filtering the wastewater by pressure filtration, the relevant personnel control the hydraulic rod 30 to start. The hydraulic rod 30 drives the push plate 31 to move towards the filter plate 2 to press multiple filter plates 2 tightly. A filtration chamber is formed between the multiple filter plates 2. Subsequently, the relevant personnel can convey the wastewater into the water inlet pipe 12 through a liquid pump. After the wastewater enters the filtration chamber, it flows into the groove through the filtration of the filter cloth and is discharged from the drain pipe 15 through the groove. At the same time, the solid particles and suspended substances in the wastewater can be intercepted by the filter cloth, and finally a filter cake is formed.

[0053] After the filtration is completed, the relevant personnel control the hydraulic rod 30 to drive the push plate 31 to move away from the filter plate 2. Subsequently, the relevant personnel control the first ball screw 400 to rotate. The first ball screw 400 drives the first slider 401 to move away from the filter plate 2. At the same time, the first slider 401 drives the outermost second slider 410 to move. With the cooperation of the first connecting rod 412, it drives other second sliders 410 to move synchronously. Finally, multiple filter plates 2 are separated from each other. Refer to Figure 5 , there is a certain gap between adjacent filter plates 2. At this time, some of the filter cake may directly fall into the collection tank 14 under the action of gravity.

[0054] Finally, the relevant personnel control the rotation shaft 50 to rotate. The rotation shaft 50 drives the cam 51 to rotate. During the rotation of the cam 51, it drives the connecting plate 10 and the filter plate 2 to vibrate to shake the filter cake on the filter cloth into the collection tank 14, thereby accelerating the discharging speed of the filter cake and also avoiding the filter cake remaining on the filter plate 2. At the same time, with the cooperation of the second transmission component 8, it can also drive the second ball screw 60 to rotate and move the filter cake in the collection tank 14 out through the cleaning plate 62.

[0055] In summary, the plate and frame pressure filtration equipment of the embodiment of the present application can realize the rapid synchronous separation of multiple tightly fitting filter plates, is easy to operate, and uses the auxiliary blanking component to vibrate them simultaneously, thereby accelerating the peeling process of the filter cake and improving the blanking efficiency and speed of the filter cake.
