Description

Technical Field

[0001] This utility model relates to the technical field of boron carbide processing and filtration equipment, specifically a boron carbide slurry filtration device. Background Technology

[0002] Boron carbide is one of the three hardest known materials and is commonly used in industrial products such as tank armor and bulletproof vests. In the boron carbide synthesis process, pickling is used to remove metallic impurities such as iron. After pickling, a filter press is used to separate the pickling slurry from the boron carbide particles.

[0003] Currently available boron carbide slurry filter presses are mainly used for solid-liquid separation and impurity removal in the boron carbide production process. By repeatedly injecting deionized water into the boron carbide slurry and squeezing it, residual acid and ionic impurities are replaced. At the same time, the filter press applies high pressure to the slurry, causing the liquid to pass through the filter medium (filter cloth or filter plate), while the boron carbide particles are trapped to form a filter cake, which can thoroughly remove residual acid ions and other reaction byproducts in the slurry.

[0004] However, in most existing filter press devices, the boron carbide filter cake tends to adhere to the surface of the filter cloth after the boron carbide slurry is filtered. This often requires manual inspection and removal of any remaining filter cake, which is time-consuming and has certain drawbacks. Therefore, we propose a boron carbide slurry filter press device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a boron carbide slurry filter press device to solve the problem mentioned in the background art that, after the existing filter press device filters the boron carbide slurry, the boron carbide filter cake easily adheres to the surface of the filter cloth, which often requires manual inspection and removal of the remaining filter cakes, which is quite time-consuming.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a boron carbide slurry pressure filter device, comprising a frame mechanism and a compression mechanism installed at one end of the frame mechanism, a filter block being fixedly installed on the telescopic end of the compression mechanism, a filter baffle being fixedly installed at the end of the frame mechanism away from the compression mechanism, a filter assembly being movably installed inside the frame mechanism between the compression mechanism and the filter baffle, and a pushing mechanism being provided inside the filter assembly;

[0007] The filter press assembly includes filter frames evenly distributed inside the frame mechanism, and the filter frames have filter cavities inside, and filter cloth is symmetrically fixedly connected inside the filter cavities. The feeding mechanism includes a spring assembly disposed inside the filter cloth.

[0008] As a preferred embodiment of the present invention, the compression mechanism includes a hydraulic cylinder fixedly mounted on the frame mechanism, and one end of the hydraulic cylinder is provided with a hydraulic telescopic rod fixedly connected to the filter block. The filter block and the filter assembly are both movably arranged inside the frame mechanism along the axial direction of the hydraulic telescopic rod.

[0009] As a preferred embodiment of this invention, the filter cavity includes a liquid cavity portion located inside the filter cloth and a filter cake portion located outside the filter cloth.

[0010] As a preferred embodiment of the present invention, the filter press assembly further includes a drain pipe disposed inside the filter frame, and the filter frame is provided with a drain channel that connects the liquid chamber and the drain pipe.

[0011] As a preferred technical solution of this utility model, the filter press assembly further includes a fixed tube disposed inside the filter chamber. The fixed tube is fixedly connected to the filter frame through a support mechanism. A washing liquid inlet pipe is fixedly disposed at the end of the filter press baffle away from the filter press assembly. The fixed tube and the washing liquid inlet pipe are configured in cooperation.

[0012] As a preferred embodiment of this utility model, the pushing mechanism is distributed at equal angles to the axis of the fixed tube inside the filter press assembly, and the pushing mechanism also includes an installation groove opened inside the filter frame, and a spring is provided inside the installation groove.

[0013] As a preferred technical solution of this utility model, the spring plate assembly is symmetrically arranged inside the filter press assembly through the mounting groove, and the spring plate assembly includes a limiting plate fixedly connected to both ends of the spring. The limiting plate is slidably connected to the filter frame through the mounting groove.

[0014] As a preferred technical solution of this utility model, the spring assembly further includes a pressure plate disposed on the inner side of the filter cloth, and a connecting piece that supports the pressure plate is fixedly connected between the pressure plate and the limiting piece.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the boron carbide slurry filter press device can automatically complete the filter cake dropping operation, avoid the boron carbide filter cake from adhering to the surface of the filter cloth, and solve the problem that the existing filter press device requires manual dropping of the filter cake after filtering the boron carbide slurry, which is a relatively time-consuming operation.

[0016] 1. By setting a feeding mechanism inside the filter press assembly, when the filter press is completed and the boron carbide filter cake is discharged, the filter press assembly separates into units. The limiting plate is pushed outward by the elastic force of the spring and drives the pressing plate to move towards the filter cloth side. The pressing plate pushes the filter cloth outward, causing the filter cloth to deform, thereby causing the boron carbide filter cake on the outside of the filter cloth to separate from the filter cloth and fall off, which can play the role of autonomous material discharge.

[0017] 2. The spring plate assembly is supported by a spring and elastically set inside the mounting groove. When the filter press block pushes the filter press assembly to press the filter press assembly against the filter press baffle and perform filter pressing, the limiting plate is squeezed and moves inward to the filter frame and retracts into the mounting groove. At this time, the pressing plate is attached to the inner surface of the filter cloth and does not squeeze the filter cloth, allowing the filter cloth to filter the material. Conversely, when the filter press assembly separates, the spring plate assembly automatically pops out and can automatically lift the boron carbide filter cake on the outside of the filter cloth, which facilitates the automatic material dropping operation without manual operation, saving production costs.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a boron carbide slurry filter press device, including a frame mechanism 100 and a compression mechanism 200 installed at one end of the frame mechanism 100. A filter press block 300 is fixedly installed on the telescopic end of the compression mechanism 200, specifically as follows: Figure 1 and Figure 2 As shown, a filter baffle 400 is fixedly installed at one end of the frame mechanism 100 away from the compression mechanism 200, and a filter assembly 500 is movably installed inside the frame mechanism 100 between the compression mechanism 200 and the filter baffle 400. Meanwhile, the compression mechanism 200 includes a hydraulic cylinder fixedly installed on the frame mechanism 100, and one end of the hydraulic cylinder is provided with a hydraulic telescopic rod fixedly connected to the filter block 300. Since the filter block 300 and the filter assembly 500 are both movably arranged inside the frame mechanism 100 along the axial direction of the hydraulic telescopic rod, the hydraulic cylinder drives the hydraulic telescopic rod to extend, which can push the filter block 300 toward the filter assembly 500, thereby pressing the filter assembly 500 between the filter block 300 and the filter baffle 400.

[0028] Furthermore, the filter press assembly 500 includes filter frames 501 evenly distributed inside the frame mechanism 100, and filter chambers 502 are formed inside the filter frames 501. Filter cloths 503 are symmetrically fixedly connected inside the filter chambers 502. Figure 3 and Figure 4 As shown, the filter press assembly 500 also includes a fixed tube 504 disposed inside the filter chamber 502, and the fixed tube 504 is fixedly connected to the filter frame 501 through a support mechanism. Meanwhile, a washing liquid inlet pipe is fixedly disposed at the end of the filter press baffle 400 facing away from the filter press assembly 500, and the fixed tube 504 is configured to cooperate with the washing liquid inlet pipe, as detailed below. Figure 7 As shown in the figure, the boron carbide washing liquid slurry is fed into the filter press assembly 500 through the washing liquid inlet pipe, and flows from one side of the filter press baffle 400 to the side of the filter press block 300 through the fixed pipe 504, thereby filling the inner side of the filter press assembly 500 with the boron carbide washing liquid slurry.

[0029] Furthermore, the filter chamber 502 includes a liquid chamber portion located inside the filter cloth 503 and a filter cake portion located outside the filter cloth 503, specifically as follows: Figure 3 and Figure 4As shown, the boron carbide washing liquid slurry is filtered through the filter cloth 503. The liquid in the boron carbide washing liquid slurry passes through the filter cloth 503 and enters the liquid chamber. The boron carbide particles are retained in the filter cake part due to their large particle size, forming a boron carbide filter cake. At the same time, the filter press assembly 500 also includes a drain pipe 505 opened inside the filter frame 501. The filter frame 501 is provided with a drain channel that connects the liquid chamber part and the drain pipe 505. The liquid in the liquid chamber part of the filter chamber 502 flows to the drain pipe 505 through the drain channel and is discharged through the drain pipe 505.

[0030] Specific examples Figure 4 and Figure 5 As shown, the filter press assembly 500 is internally provided with a pushing mechanism 600, and the pushing mechanism 600 is distributed at equal angles to the axis of the fixed tube 504 inside the filter press assembly 500. The pushing mechanism 600 also includes a mounting groove 610 formed inside the filter frame 501, and a spring 620 is provided inside the mounting groove 610. Figure 5 and Figure 6 As shown, the feeding mechanism 600 includes a spring plate assembly 630 disposed inside the filter cloth 503, and the spring plate assembly 630 is symmetrically disposed inside the filter press assembly 500 through the mounting groove 610.

[0031] Furthermore, the spring assembly 630 includes limiting pieces 631 fixedly connected to both ends of the spring 620, and the limiting pieces 631 are slidably connected to the filter frame 501 through the mounting groove 610. Simultaneously, the spring assembly 630 also includes a pressing piece 633 disposed inside the filter cloth 503, and a connecting piece 632 fixedly connected between the pressing piece 633 and the limiting pieces 631 to support the pressing piece 633. Figure 5 and Figure 6 As shown, when the filter press block 300 pushes the filter press assembly 500 to press the filter press assembly 500 against the filter press baffle 400 and perform filter pressing, the limiting piece 631 is squeezed and moves towards the inside of the filter frame 501 and compresses the spring 620. The limiting piece 631 retracts into the inside of the mounting groove 610. At this time, the pressing piece 633 is attached to the inner surface of the filter cloth 503 and does not squeeze the filter cloth 503.

[0032] Conversely, when the filter press is completed and the boron carbide filter cake is discharged, the filter press assembly 500 separates into individual units. The limiting plate 631 is pushed outward from the mounting groove 610 by the elastic force of the spring 620, and drives the pressing plate 633 to move towards the filter cloth 503. The pressing plate 633 pushes the filter cloth 503 outward, causing the filter cloth 503 to deform, thereby assisting the boron carbide filter cake on the outside of the filter cloth 503 to separate from the filter cloth 503 and fall off.

[0033] The working principle of this utility model is as follows: When using this boron carbide slurry filter press, the compression mechanism 200 first drives the filter press block 300 to move towards the filter press assembly 500, so that the filter press block 300 presses the filter press assembly 500 against the outside of the filter press baffle 400. Figure 1 and Figure 7 As shown in the figure, boron carbide washing slurry is introduced into the filter press assembly 500 through the washing liquid inlet pipe, so that the boron carbide washing slurry flows from one side of the filter press baffle 400 to one side of the filter press block 300 through the fixed pipe 504, thereby filling the inner side of the filter press assembly 500 with boron carbide washing slurry.

[0034] Combination Figure 3 and Figure 4 As shown, the boron carbide washing liquid slurry is filtered through filter cloth 503. The liquid in the boron carbide washing liquid slurry passes through filter cloth 503 and enters the liquid chamber part, while the boron carbide particles are trapped in the filter cake part due to their large particle size, forming a boron carbide filter cake. At the same time, the liquid in the liquid chamber part of filter chamber 502 flows to the drain pipe 505 through the drain channel and is discharged through the drain pipe 505.

[0035] Specific examples Figure 2 As shown, when the filter press is completed and the boron carbide filter cake is discharged, the filter press assembly 500 separates into individual units, combined with... Figure 5 and Figure 6 As shown, the limiting piece 631 is pushed outward of the mounting groove 610 by the elastic force of the spring 620, and drives the pressing piece 633 to move towards the filter cloth 503. The pressing piece 633 pushes the filter cloth 503 outward, causing the filter cloth 503 to deform, thereby causing the boron carbide filter cake on the outside of the filter cloth 503 to separate from the filter cloth 503 and fall off, assisting in the material falling off and preventing the boron carbide filter cake from adhering to the outside of the filter cloth 503.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
