Description

Technical Field

[0001] This utility model belongs to the field of filter technology and relates to filters. Background Technology

[0002] A filter is a device used to achieve solid-liquid separation or impurity removal during chemical reactions or material handling processes.

[0003] Existing filters, such as the filter device for a multifunctional filter dryer disclosed in Chinese patent literature [Patent No.: 201510378358.2; Application Publication No.: CN104922957B], include a filter plate and a filter cloth. The filter plate is provided on the bottom plate, and a first flange is fixed on the outer circle of the bottom plate. A second flange with an annular shape is provided on the first flange. The lower end of the second flange is sealed to the upper end of the first flange. The outer side of the second flange is sealed to the tank body. An annular groove is provided on the second flange. The filter cloth covers the filter plate and the annular groove. A pressure ring is fixed on the annular groove. The pressure ring is provided on the filter cloth, and the filter cloth is fixed to the second flange by the pressure ring.

[0004] This type of filtration device filters materials through the cooperation of filter cloth and filter plate. The solid filter cake is placed on the filter cloth and removed from the discharge assembly at the bottom of the tank's outer perimeter. The filtrate is discharged directly through the discharge port. However, in this type of filtration device, the filtrate is directly delivered to the storage tank through the discharge connector during filtration. When the storage tank is full, the discharge connector must be closed, the full storage tank removed, and the discharge connector connected to an empty storage tank. Then, the discharge connector is opened again to allow the filtrate to flow into the empty storage tank. During this tank replacement process, filtration stops, leaving the equipment idling. This increases filtration time, reduces filtration efficiency, and increases energy consumption. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a filter that solves the technical problem of how to improve the filtration efficiency of the filter.

[0006] The objective of this utility model can be achieved through the following technical solution: a filter, comprising a filter assembly and an upper tank with a through bottom, wherein a discharge assembly is provided at the bottom of the outer peripheral wall of the upper tank, characterized in that the filter further comprises a lower tank with an opening at the top and a support cylinder located in the lower tank, wherein a liquid outlet connector is provided at the bottom of the lower tank, the filter assembly is fixedly connected to the top of the lower tank and blocks the opening, the top of the support cylinder abuts against the filter assembly, the bottom of the support cylinder abuts against the lower tank, and the top of the lower tank and the filter assembly are both sealed and embedded in the bottom of the upper tank.

[0007] During filtration, the material is located in the upper tank and passes through the filter assembly. The filtrate enters the lower tank and then flows to the storage tank through the outlet. When the storage tank is full, the outlet is closed and an empty storage tank is used. During this process, the material continues to pass through the filter assembly, and the filtrate enters the lower tank for temporary storage. This means the filter is always running, and the filter assembly is always filtering; there is no issue of filtration stopping. This improves the filter efficiency, reduces filtration time, and lowers energy consumption. After filtration, the filter cake is discharged through the discharge assembly. The lower tank design suspends the filter assembly, and the support cylinder supports the assembly, preventing deformation under stress, ensuring stability, extending service life, reducing failure rate, and ultimately improving filter efficiency.

[0008] In the aforementioned filter, the outlet connector is located at the center of the bottom of the support cylinder. The bottom of the support cylinder has several spaced-apart notches that connect the interior of the support cylinder to the interior of the lower tank. This structure ensures that the filtrate can flow through the notches to the outlet connector, thus ensuring proper filtration.

[0009] In the aforementioned filter, a number of spaced-apart ribs are fixedly connected to the bottom of the support cylinder, and these ribs are fixedly connected to the lower tank body. The ribs improve the firmness of the support cylinder connection, enhance the stability of the filter, and thus improve the filter's filtration efficiency.

[0010] In the aforementioned filter, a sealing ring is provided on the circumferential outer wall of the filter assembly. The bottom of the inner circumferential wall of the upper tank is a conical surface, with the inner diameter of the top of the conical surface being smaller than the inner diameter of the bottom. The sealing ring abuts against the conical surface to seal the upper tank and the lower tank together. The angle of the conical surface is small, ensuring that the sealing ring can be pressed tightly and sealed when it moves upward, thereby improving the sealing effect.

[0011] In the aforementioned filter, an upper flange is fixedly connected to the outer peripheral wall of the upper tank, and a lower flange is fixedly connected to the outer peripheral wall of the lower tank. The upper flange and the lower flange are fastened together by fasteners, thus connecting the upper tank and the lower tank. This structure facilitates the connection between the upper and lower tanks.

[0012] In the aforementioned filter, the filter assembly includes a filter plate, a first ring, a second ring, and a pressure ring. The filter plate is embedded and fixedly connected to the first ring, the second ring is fixedly connected to the top of the lower tank, and the pressure ring is fitted onto the first ring. The filter assembly is fixedly connected to the top of the lower tank by fasteners passing through and locking the pressure ring, the first ring, and the second ring. This structure is simple and easy to fix. In practical operation, a filter screen or filter cloth can be installed on the filter plate.

[0013] In the aforementioned filter, the bottom wall of the discharge port of the discharge component is flush with the top wall of the filter component. This structure precisely controls the distance between the filter plate and the discharge port, minimizing the amount of filter cake residue during the discharge process and effectively improving material utilization.

[0014] In the aforementioned filter, a jacket, an insulation layer, an inlet pipe, and an outlet pipe are fixedly connected to the bottom of the lower tank. The jacket is located between the lower tank and the insulation layer. The inner end of the inlet pipe passes through the insulation layer and connects to the inlet of the jacket. The inner end of the outlet pipe passes through the insulation layer and connects to the outlet of the jacket. If necessary, a refrigerant or a heating medium can be introduced into the jacket to adjust the temperature of the filtrate, ensuring it meets actual requirements.

[0015] Compared with the prior art, the filter provided by this utility model has the following advantages:

[0016] 1. This filter uses a lower tank to temporarily store the filtrate, ensuring that the filter is always running and the filtration components are always filtering. This eliminates the problem of filtration stopping, improves the filtration efficiency, reduces filtration time, and lowers energy consumption.

[0017] 2. The design of the lower tank of this filter suspends the filter assembly in the air, while the support cylinder supports the filter assembly, preventing it from deforming under stress, ensuring its stability, extending its service life, reducing the failure rate, and thus improving the filter's filtration efficiency.
