Problems solved by technology

It is easy to cause deformation of the filter cloth and shorten the service life
[0005] 2. Increased energy consumption: the shrinkage of the filter cloth leads to cracks in the filter cake, and then the atmosphere communicates with the vacuum chamber, and the air is sucked into the vacuum chamber to reduce the vacuum degree, affect the dehydration effect, and increase power consumption

Embodiment Construction

[0016] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] Such as figure 1 with figure 2 As shown, the present invention includes a filter press body 1 and a feed pipe 2 for conveying the finished slurry into the filter body 1. The feed pipe 2 is provided with a heat exchanger 3 that can reduce the temperature of the finished slurry. The heat exchanger 3 includes a heat exchanger body 3a with a cavity inside, the lower end of the heat exchanger body 3a is provided with a finished slurry inlet 301 communicating with the cavity, and the upper end of the heat exchanger body 3a is provided with a cavity The cavity is connected to the finished slurry outlet 302, and a number of interconnected pipes 303 are arranged in the cavity, and the pipes 303 are provided with a cooling water inlet 304 for inflowing cold water and a hot water outlet 305 for outflowing hot water. A centrifugal pump 6 is provid...

Abstract

The invention discloses a filter press. The filter press comprises a filter press body and an inlet pipe used for feeding finished-product slurry into the filter press body. The inlet pipe is provided with a heat exchanger used for cooling the finished-product slurry. According to the filter press, the service lifetimes of filter cloths and filter boards of the press filter are prolonged and energy is saved.

Description

Technical field [0001] The invention relates to a filter press. technical background [0002] At present, the filter press is widely used in industrial production as a solid-liquid separation device. High temperature, high pressure, humid environment, etc. will have a greater impact on the service life of the filter press, directly affecting the production efficiency and economic benefits of the enterprise. [0003] The direct use of filter press to separate high-temperature solid-liquid mixtures has the following disadvantages: [0004] 1. Easy to damage the filter plate of the filter press: higher temperature can cause the spring bridge phenomenon at the contact point of the filter cake and the filter plate ("Quanhua" refers to the shell formed by the precipitation of salts around the mineral). Increase the peeling resistance of the filter cake, which has a greater impact on the service life of the filter cloth and filter plate. At the same time, the commonly used nylon filter c...
