Description

Technical Field

[0001] This utility model relates to the field of filter machines, and specifically to a vertical filter machine. Background Technology

[0002] Existing filter presses typically employ a parallel design with multiple filter plates (filter units), with all filtered material collected in a single main discharge pipe. This centralized discharge structure has revealed significant drawbacks over long-term use: when one or more filter units experience reduced filtration efficiency or failure due to clogging or media wear, it directly impacts the overall discharge efficiency and filtration quality of the equipment. Since the material must be discharged through the main pipe, a single filter unit failure can cause abnormal system resistance, leading to complete equipment malfunction. In such cases, maintenance personnel often need to shut down the machine for a comprehensive inspection and replacement of all filter units, increasing maintenance costs and downtime, and reducing production continuity. Utility Model Content

[0003] This utility model provides a vertical filter to solve the problems of the prior art.

[0004] The objective of this utility model can be achieved through the following technical solution: A vertical filter includes a vertical tank body, with an inlet on one side of the lower end of the vertical tank body that communicates with the interior of the vertical tank body, and several sets of outlets in the middle of the vertical tank body. Several sets of filter units are arranged at intervals inside the vertical tank body. Material entering the interior of the vertical tank body through the inlet passes through the filter units and enters the inner cavity of the filter units. Each set of outlets communicates with the inner cavity of the filter units.

[0005] As a further improvement, the vertical tank body is provided with an overflow port that connects to the interior of the vertical tank body, and the overflow port is located above the discharge port.

[0006] A further improvement is that the top of the vertical tank is provided with a filling cap, and the top side of the filling cap and the bottom side of the vertical tank are provided with internally threaded pressure gauge ports.

[0007] As a further improvement, the bottom of the vertical tank is provided with a slag discharge port.

[0008] As a further improvement, a vent is provided on the other side of the top of the filling cap.

[0009] Compared with existing technologies, the advantages of this vertical filter are as follows: Each filter unit has an independent filter channel and internal cavity structure. When the material flows through the filter unit, impurities are trapped by the filter media, while the qualified filtrate passes through the filter media and enters the internal cavity of the filter unit. Each set of discharge ports is directly connected to the internal cavity of the corresponding filter unit, forming an independent diversion pipeline. The filtrate of each filter unit is discharged through its corresponding discharge port. When a filter unit fails due to blockage, damage, or other reasons, only the valve of the corresponding discharge port needs to be closed. Other filter units can continue to discharge filtrate normally through their respective discharge ports, avoiding the problem of the entire machine shutting down due to the failure of a single unit in the traditional structure.

[0012] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0013] Example 1 A vertical filter includes a vertical tank body 1. The lower end of the vertical tank body 1 is provided with an inlet 11 that communicates with the interior of the vertical tank body 1. The middle part of the vertical tank body 1 is provided with a plurality of discharge ports 12. The interior of the vertical tank body 1 is provided with a plurality of filter units 13 arranged at intervals. The material entering the interior of the vertical tank body 1 through the inlet 11 is filtered by the filter unit 13 and enters the inner cavity 131 of the filter unit 13. Each discharge port 12 is connected to the inner cavity 131 of the filter unit 13.

[0014] like Figures 1-3 As shown, the working principle of this utility model is as follows: The vertical tank body forms a closed filtration space. Material enters the tank through the inlet at the bottom and flows upwards under pressure, contacting several spaced-apart filter units. Each filter unit has an independent filtration channel and internal cavity structure. As the material flows through the filter unit, impurities are trapped by the filter media, while the compliant filtrate passes through the media and enters the internal cavity of the filter unit. Each set of outlets is directly connected to the corresponding filter unit's internal cavity, forming an independent branch pipeline. The filtrate from each filter unit is discharged through its corresponding outlet, without needing to be collected into a main pipeline. Conventional filtration units typically consist of components such as filter frames and filter cloths, representing existing technology. The filter cloth serves as the filtration medium for solid-liquid separation, while the internal space of the filter frame forms a cavity for temporary storage of the filtrate. In this structure, the internal cavity of the filtration unit is connected one-to-one to the discharge port outside the tank via pipes, making each filtration unit an independent filtration subsystem.

[0015] When a filter unit fails due to blockage, damage, or other reasons, only the valve at the corresponding outlet needs to be closed. Other filter units can continue to discharge filtrate normally through their respective outlets, avoiding the problem of a single unit failure causing the entire machine to shut down in traditional structures. Moreover, by observing the flow rate and filtrate quality at each outlet, the unit can be replaced or cleaned selectively without disassembling all filter components, significantly reducing maintenance time. As a further preferred embodiment, the vertical tank body 1 is provided with an overflow port 14 communicating with the interior of the vertical tank body 1, and the overflow port 14 is located above the discharge port 12. The height of the overflow port 14 is higher than the installation position of all filter units, and it is connected to the interior of the tank body through a pipe to form an overpressure protection channel. When the feed rate is too large, or some filter units are blocked, causing the liquid level in the tank to rise to the height of the overflow port, the excess material will be discharged through the overflow port to prevent abnormal pressure rise in the tank.

[0016] As a further preferred embodiment, the vertical tank body 1 is provided with a filling cap 2 at the top, and pressure gauge ports 15 with internal threads are provided on one side of the top of the filling cap 2 and the bottom side of the vertical tank body 1. Both the pressure gauge ports at the top of the filling cap and the bottom of the tank body are designed with internal threads, allowing pressure gauges to be installed to monitor the pressure at different locations inside the tank. The top pressure gauge mainly reflects the pressure in the upper gas phase space of the tank body, while the bottom pressure gauge monitors the pressure at the material inlet. By comparing the pressure difference between the two locations, the degree of blockage of the filter unit can be determined: when the pressure difference exceeds the normal range, it indicates that the resistance of the filter unit has increased, and blockage may exist.

[0017] As a further preferred embodiment, the vertical tank 1 is provided with a slag discharge port 16 at its bottom. The slag discharge port at the bottom is controlled by a valve, and its position corresponds to the lowest point of the tank. During the filtration process, some settling impurities in the material will accumulate at the bottom of the tank due to gravity, while impurities intercepted by the filtration unit may also fall to the bottom of the tank due to backwashing or gravity. When the slag discharge port valve is opened, the accumulated impurities can be discharged out of the tank under pressure or gravity.

[0018] As a further preferred embodiment, a vent 17 is provided on the other side of the top of the filling cap 2. The vent at the top of the filling cap is connected to the atmosphere through a valve, mainly used to release residual pressure inside the tank when the equipment is stopped or maintained. Before the filter is started, air inside the tank can also be discharged through the vent to prevent air from mixing with the material and affecting the filtration effect.

[0019] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
