Description

Technical Field

[0001] The utility model relates to the field of plate and frame filter presses, in particular to a plate and frame filter press and a filter cake material self-falling cutting device thereof. Background Art

[0002] A plate and frame filter press, also known as a plate filter press, is a machine that applies mechanical force to one side of the filter medium to achieve filtration. Due to its large filtration area, high flow rate, and wide range of applications, it is widely used in the pharmaceutical, chemical, and food industries.

[0003] In the production of molecular sieve raw powder, water washing and filtration are essential steps. Typically, a large amount of water is squeezed out of the material through the plate and frame filter press, forming a filter cake. This cake is then dried again in other drying equipment to become a qualified product. However, due to the large size of the filter cake removed from the plate and frame filter press, additional labor is required to break the filter cake into small pieces before feeding it into the dryer for drying. This not only wastes labor costs but also increases the workload of workers. Utility Model Content

[0018] To facilitate understanding of the present invention, the present invention is described in more detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0019] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art in the field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0020] An embodiment of a plate and frame filter press of the present utility model is as follows Figure 1-Figure 2 As shown, it includes a housing 1, a filter cake discharge port 2 is provided at the lower end of the housing 1, and a filter cake material self-falling cutting device 4 is provided below the filter cake discharge port 2. In this embodiment, the filter cake material self-falling cutting device includes a device frame, which includes a storage bin 5 with an upward opening, and a discharge port 7 is provided at the lower part of the storage bin 5. A cutting plate 6 is provided inside the storage bin, and the cutting plate is as shown in FIG. Figure 2 As shown, the cutting plate includes a plurality of cutting bars 16, which are cross-arranged to form a grid structure, so that the filter cake is cut into a plurality of small pieces under the impact of its gravity.

[0021] In this embodiment, the cutting plate 6 is a movable plate hinged at one end. Specifically, the cutting plate 6 has a hinged end 8 hinged to the inner wall of the storage bin, and the other end 15 is connected to the driving mechanism 12. A blanking channel 9 is provided on the cutting plate near the hinged end. Figure 2 As shown. The driving mechanism 12 can drive the cutting plate to rotate up and down around the hinged end so that the material on the cutting plate slides along the cutting plate and drops through the blanking channel 9. In this embodiment, the size of the blanking channel is larger than the size of a grid hole in the grid structure. The purpose of this setting is that since the filter cake material 3 falls on the cutting plate 6, there may be larger blocks among the broken blocks, which cannot pass through the grid holes of the cutting plate, resulting in the subsequent cutting of the filter cake material in the scheme. Therefore, it is necessary to lift one end of the cutting plate through the driving mechanism to make the cutting plate in an inclined state. The above-mentioned larger filter cake material blocks will slide along the inclined cutting plate and fall into the discharge bin below through the blanking channel.

[0022] The storage bin wall is provided with a through-hole 10 through which the other end 15 of the cutting plate passes and allows the cutting plate to move up and down. A drive mechanism 12 includes a drive cylinder, which can be an oil cylinder. The piston rod of the drive cylinder is hinged to one end of the cutting plate. A support plate 13 is provided on the outer wall of the storage bin 5, and the end of the cylinder body of the drive cylinder is hinged to the support plate. A soft baffle 11 is provided between the cutting plate 6 and the storage bin 5 at the through-hole 10. The upper end of the soft baffle is connected to the storage bin and the other end is connected to the cutting plate to prevent broken filter cake from splashing out of the through-hole 10. The soft baffle can be a soft rubber sheet that can block the through-hole portion above the cutting plate as the cutting plate rotates. This prevents broken filter cake fragments from falling through the through-hole when the cutting plate is in a horizontal position, ensuring that all broken filter cake fragments fall into the storage bin, avoiding the surrounding filter cake fragments from falling. This not only ensures the safety of surrounding personnel but also allows the broken filter cake to be discharged in a centralized manner.

[0023] In the above description of this specification, unless otherwise expressly specified or limited, terms such as "fixed," "mounted," "connected," or "connected" should be understood broadly. For example, the term "connected" can refer to a fixed connection, a removable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal connection between two components or the interaction between two components. Therefore, unless otherwise expressly defined in this specification, those skilled in the art can understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0024] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "up", "down", "front", "back", "left", "right", "length", "width", "thickness", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "center", "longitudinal", "lateral", "clockwise" or "counterclockwise", etc., which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the drawings of this specification, and are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.

[0025] In addition, the terms "first" or "second" used in this specification to refer to numbers or ordinal numbers are used for descriptive purposes only and should not be understood as explicitly or implicitly indicating relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this specification, "plurality" means at least two, such as two, three or more, etc., unless otherwise clearly specified.

[0026] In other embodiments of the present invention, the soft baffle can also be replaced by a composite plate, which includes multiple baffles connected one by one up and down and can overlap each other. The composite plate is a prior art and its specific structure will not be described in detail here; the oil cylinder can also be replaced by an air cylinder or an electric push rod; the driving mechanism also includes a lifting rope, one end of the lifting rope is connected to the cutting plate and the other end is connected to the winch.

[0027] The embodiment of the filter cake material self-falling cutting device of a plate and frame filter press of the present invention has the same structure as the filter cake material self-falling cutting device in each embodiment of the above-mentioned plate and frame filter press, and will not be described in detail here.
