Description

Technical Field

[0001] The utility model relates to the field of filter presses, in particular to a filtrate automatic diversion and liquid receiving tank. Background Art

[0002] Filter presses are commonly used filtration equipment in the solid-liquid separation industry, widely used in sewage treatment, food, chemical, coal, and other industries. The receiving trough is a liquid receiving device installed on the side of the filter press. During operation, the filtrate extracted from the material is discharged from the filter chamber between the filter plates as an open flow. Specifically, the open flow is discharged directly through the nozzles installed on the side of the filter plates, then enters the receiving trough at the bottom of the side of the filter press, and then enters the next process step through the drainage pipe installed in the receiving trough.

[0003] In reality, filter press operation can cause inconsistencies in filtrate purity or solids content between the initial and later stages of discharge, or changes in filtrate purity or solids content due to turbidity caused by filter cloth damage. Certain industries that require high-purity filtrate often recycle the turbid filtrate for refiltration. To improve filtration efficiency, adding a diversion function to reduce the filtration burden is desirable.

[0004] Patent announcement number CN214913685U discloses a diversion-type liquid receiving tank for a filter press. The liquid receiving tank adopts a partitioned design, and a hose is added to each open-flow liquid nozzle. When diversion is required, each hose is manually placed in the clear liquid chamber and the turbid liquid chamber. Since each filter press is equipped with dozens or even hundreds of open-flow liquid nozzles, it is not only inconvenient to operate in actual application, but also has defects such as low diversion efficiency and labor-intensiveness. Utility Model Content

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A filtrate automatic diversion and receiving trough comprises a trough body, wherein a partition is provided in the trough body to divide the internal space of the trough body into a clear liquid chamber and a turbid liquid chamber in the transverse direction, a movable diverter is provided on the top of the partition, and a driving mechanism that cooperates with the movable diverter is provided on the trough body to drive the movable diverter to move transversely above the clear liquid chamber and the turbid liquid chamber, so that the filtrate is alternately received into the turbid liquid chamber and the clear liquid chamber through the movable diverter.

[0012] Furthermore, a baffle is provided at the bottom of the second longitudinal side of the guide plate, the lower end of the baffle is not higher than the top of the partition, and a notch is left on the baffle for installing a resistance reduction component.

[0013] Furthermore, the cross section of the support member is L-shaped or a right triangle.

[0014] Furthermore, the slide is connected to the support member via an L-shaped fixing seat, and L-shaped supporting ribs are further provided on the support member between adjacent L-shaped fixing seats.

[0015] Furthermore, a top portion of one of the longitudinal side walls of the trough body is higher than a middle portion of the guide plate, and the longitudinal side wall is inclined toward the top portion of the guide plate.

[0016] Furthermore, the driving mechanism includes two telescopic cylinders respectively fixed to the two lateral side walls of the trough body, and the driving end of each telescopic cylinder is connected to a connecting rod through a mounting seat.

DETAILED DESCRIPTION

[0029] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0031] like Figure 1-3 As shown, in this embodiment, the filtrate automatic diversion receiving tank includes a tank body 100, wherein a partition 110 is provided within the tank body 100 to divide the internal space of the tank body into a clear liquid chamber and a turbid liquid chamber in the transverse direction. A movable diverter 200 is provided on the top of the partition 110. The tank body 100 is provided with a driving mechanism 300 that cooperates with the movable diverter 200 to drive the movable diverter 200 to move laterally above the clear liquid chamber and the turbid liquid chamber, so that the filtrate is alternately transferred to the turbid liquid chamber and the clear liquid chamber through the movable diverter 200. The tank body 100 is provided with a liquid outlet 130 that is respectively connected to the turbid liquid chamber and the clear liquid chamber.

[0032] Working principle: This filtrate automatic diversion receiving tank is installed on the side of the filter press, specifically below the open outflow nozzle, when used on the filter press. Figure 7 This is a specific application method. The following application process is explained by taking the clear liquid chamber inside (close to the filter press) and the turbid liquid chamber outside (far away from the filter press) as an example. At this time, the open flow outlet nozzle is set corresponding to the clear liquid chamber.

[0033] When in use, when the driving mechanism 300 moves the movable diverter 200 to the upper side of the turbid liquid chamber, Figure 2 and 7 As shown, the filtrate discharged from the open outflow nozzle will flow directly into the clear liquid chamber below; when the driving mechanism 300 moves with the movable diverter 200 to the top of the inner clear liquid chamber, as shown in FIG. Figure 1 and 8 As shown, the filtrate discharged from the open effluent nozzle first flows onto the movable diverter 200, and then flows from the movable diverter 200 into the outer turbid liquid chamber. The inward and outward lateral movement of the movable diverter 200 realizes the separation of the clear liquid and turbid liquid discharged from the open effluent nozzle at different stages of filtration. The separated turbid liquid can be discharged through the liquid outlet and discharged into the corresponding pipeline for the next process or recycled to the slurry tank for further processing.

[0034] like Figure 1 、 4 As shown in Figure 5, in one specific embodiment, the movable diverter 200 includes a guide plate 210, and the guide plate 210 is tilted so that its first longitudinal side is higher than the second longitudinal side to better play a drainage role. A support member 220 is provided at the bottom of the guide plate 210, and the guide plate 210 moves laterally with the support member 220 to alternately cover the clear liquid chamber and the turbid liquid chamber.

[0035] like Figure 4 As shown, in one specific embodiment, the first longitudinal side and the tops of the two transverse sides of the drainage plate 210 are provided with a surrounding edge 230 to more safely drain the filtrate.

[0036] like Figure 3 As shown in one specific embodiment, a plurality of multifunctional ribs 120 are provided on the top of the partition 100. The multifunctional ribs 120 are spaced apart longitudinally, and the two ends of each multifunctional rib 120 extend transversely and are fixed to the two longitudinal side walls of the trough body 100. The multifunctional ribs 120 can be used as both reinforcement ribs of the trough body and as tracks for the support member to run.

[0037] like Figure 3 As shown, in one specific embodiment, a resistance reducing component 240 is further provided between the support member 220 and each multifunctional rib plate 120 to reduce the running resistance. The resistance reducing component 240 includes a slider 241 fixed to the top of the multifunctional rib plate 120, and a slide 242 fixed to the bottom of the support member 220. At least two slides adopt Π-shaped plates that cooperate with the slider to limit the longitudinal position so that the support member can slide stably in the horizontal direction.

[0038] like Figure 4-5 As shown, in one specific embodiment, a baffle 250 is provided at the bottom of the second longitudinal side of the guide plate 210. The lower end of the baffle 250 is no higher than the top of the partition 110, and a notch is left in the baffle 250 for installing the resistance reduction component 240. The baffle 250 mainly serves a protective function to prevent liquid from splashing into the inner clear liquid chamber through the gap between the support member 220 and the partition 110 when it flows into the outer turbid liquid chamber.

[0039] like Figure 4 As shown in one specific embodiment, the cross-section of the support member 220 is L-shaped or a right triangle. The slide 242 is connected to the support member 220 via an L-shaped fixing seat 260. L-shaped support ribs 270 are also provided on the support member 220 between adjacent L-shaped fixing seats 260. Both the L-shaped fixing seats 260 and the L-shaped support ribs 270 are intended to increase the strength of the support member 220 and improve its stability during movement.

[0040] like Figure 4 As shown, in one specific embodiment, the top of one of the longitudinal side walls of the trough body 100 is higher than the middle of the drain plate 210, and the longitudinal side wall is inclined toward the top of the drain plate 210. Such a configuration can effectively prevent the filtrate fluid from splashing outside the trough body when entering the trough body during the drainage process through the drain plate 210.

[0041] like Figure 6As shown, in one specific embodiment, the driving mechanism 300 includes two telescopic cylinders 310 respectively fixed to the two lateral side walls of the trough body 100, which can be specifically pneumatic cylinders, electric cylinders, etc. The driving end of each telescopic cylinder 310 is connected to a connecting rod 330 through a mounting seat 320. The connecting rod 330 passes through the side wall of the end of the trough body and is fixed to the movable diverter 200. A limiting hole 140 is opened on the lateral side wall of the trough body 100 for the lateral movement of the connecting rod 330.

[0042] Preferably, two connecting rods 330 are provided in parallel above and below, so that the movement is more stable.

[0043] In actual application, a stroke sensing component may be provided on the telescopic cylinder 310 and connected to a PLC controller so as to control the telescopic cylinder to drive the movable diverter to move laterally.

[0044] Special, except Figure 7 and Figure 8 This application mode and the following application modes are also within the scope of protection of the present invention. Specifically, when the open outflow liquid nozzle is located above the outer turbid liquid chamber, Figure 7 The movable diverter needs to be arranged in a mirror image so that the filtrate can be alternately connected to the turbid liquid chamber and the clear liquid chamber.

[0045] The above specific implementation methods cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or transformation made to the implementation methods of the present utility model falls within the protection scope of the present utility model.

[0046] Anything not described in detail in the present invention is well known to those skilled in the art.
