Description

Can promote filter-pressing system of red gypsum solid content

Technical Field

The utility model relates to a filter-pressing system, concretely relates to can promote filter-pressing system of red gypsum solid content.

Background

The plate-frame filter press is widely used for machines for separating solid and liquid in the chemical field, and has the characteristics of lightness, flexibility, reliability and the like. In the production process of the red gypsum, the liquid flowing out of the concentration tower enters a plate-and-frame filter press for filter pressing to obtain a filter cake of the red gypsum. However, in the actual production process, on one hand, the solid content of the red gypsum obtained by the plate-and-frame filter press is low due to the low pressure of the dewatering pump, and on the other hand, the overflow of the first flow pipeline of the concentration tower is slow, so that the red gypsum is easy to overflow the pool and further cause accidents, and the red gypsum is stopped.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a promote red gypsum content's filter-pressing system, this system simple structure, convenient operation can be safely, fast, filter-pressing red gypsum effectively, and the solid content of the red gypsum that obtains has promoted 4-5% moreover.

The utility model discloses a realize through following technical scheme:

the utility model provides a can promote filter-pressing system of red gypsum solid content, includes concentration tower and plate and frame filter press, first plate and frame filter press, second plate and frame filter press and third plate and frame filter press have connected gradually behind the concentration tower.

And a pump body is arranged on the first plate frame filter press, the second plate frame filter press and the third plate frame filter press which are sequentially connected behind the concentration tower. The pump body is a high-pressure pump.

And the side surfaces of the first plate-and-frame filter press, the second plate-and-frame filter press and the third plate-and-frame filter press are sequentially connected with the back of the concentration tower, and blowing devices are arranged.

An overflow pipe is arranged on the concentration tower. The overflow pipe is one, two or more.

The beneficial effects of the utility model

The utility model discloses equipment is simple, can effectively improve the solid content of red gypsum, reduces the subsequent processing's of red gypsum pressure and cost. And the overflow pipeline is newly added to the overflow pipeline of the concentration tower, so that the overflow of the supernatant is smooth, the concentration of the feed liquid entering the plate and frame at the bottom is improved, the number of the plate and frame filter presses is reduced due to the starting of the overflow pipeline, the energy consumption is reduced to a certain extent, and the occurrence of overflow tank accidents is greatly reduced.

Detailed Description

For ease of description, spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Fig. 1 is a drawing of the device of the present invention.

The utility model provides a can promote filter-pressing system of red gypsum solid content, includes concentration tower and plate and frame filter press, first plate and frame filter press 2, second plate and frame filter press 3 and third plate and frame filter press 4 have connected gradually behind the concentration tower 1.

A pump body 201 is arranged on the first plate-and-frame filter press 2, the second plate-and-frame filter press 3 and the third plate-and-frame filter press 4 which are connected in sequence behind the concentration tower 1. Pump body 201 is a high-pressure pump.

The side surfaces of the first plate-and-frame filter press 2, the second plate-and-frame filter press 3 and the third plate-and-frame filter press 4 are sequentially connected with the rear part of the concentration tower 1, and a blowing device 202 is arranged.

The concentration column 1 is provided with an overflow pipe 101. The overflow pipe 101 may be one, two or more.

By using the filter pressing system, the first plate frame filter is started to reach a certain pressure, then the second plate frame filter is started to reach the maximum pressure, and meanwhile, the plate frame unloading time and the plate frame unloading process are well controlled; starting a first plate frame machine blowing device simultaneously, debugging a plate frame filter pressing program for multiple times, and searching data through whole touch; the pump body of the third plate frame filter press is a high-pressure pump, so that the material beating pressure is increased to 0.8 Mpa;

the overflow pipeline of the concentration tower is added with an overflow pipeline, so that the overflow of the supernatant is smooth, and the concentration of the feed liquid of the bottom plate feeding frame is increased.

Through plate-and-frame filter pressing program control, increase of an overflow pipeline of the concentration tower and data monitoring experiments, the solid content of a filter cake is improved by 4-5%.

The above detailed description of the embodiments of the present invention is only used as an example, and the present invention is not limited to the above described embodiments, and the modifications of the present invention are also within the scope of the present invention.
