Description

Technical Field

[0001] The utility model relates to the technical field of filter press equipment, in particular to a filter press equipment. Background Art

[0002] The filter press uses a special filter medium to apply a certain pressure to the object, causing the liquid to seep out. It is a commonly used solid-liquid separation equipment and is widely used in chemical, pharmaceutical, metallurgy, dye, food, brewing, ceramics and environmental protection industries.

[0003] The working principle of the filter press is mainly based on pressure difference. The filtered liquid enters the mixture to be treated and is added to the filter chamber or filter of the filter press. The accumulation of solid particles As the liquid passes through the filter, the solid particles gradually accumulate on the filter until a certain thickness is reached. The liquid is discharged. When the solid particles on the filter reach a certain thickness, the liquid passage speed slows down. At this time, the liquid supply is stopped and the filtered liquid is discharged. After the filtered liquid is discharged, the solid particles remain on the filter to form a retentate, which can be further processed or recycled.

[0004] The existing filter press equipment collects the generated wastewater into a designated wastewater pool after treatment, removes large suspended particles, and removes large suspended particles and debris in the wastewater through natural sedimentation, screening and other methods. The mud cakes fall directly on the ground and need to be transported manually, which has low work efficiency. Due to the gaps between solid particles and the limitations of filter media such as filter cloth, the water inside the mud cake is often unable to be completely removed, so a certain amount of water will remain, which needs to be squeezed again to facilitate subsequent processing operations.

The No. 1 grid chamber 10 and the No. 2 grid chamber are used for dry and wet separation of mud cakes, which is convenient for subsequent processing operations by the staff. Example 2

[0025] Reference Figure 1-4 , which is the second embodiment of the present utility model, which is different from the first embodiment in that: a hydraulic rod 11 is installed at the output end of the hydraulic press 2, and the bottom end of the hydraulic rod 11 is fixedly connected to a pressing plate 12 that is lifted and slidably installed in the body 1. The pressing plate 12 is used to squeeze the mud cake and squeeze out the water in the mud cake. A feeding port 13 is opened on one side of the body 1 and is connected to the inner cavity of the body 1. A guide plate 14 is rotatably connected to the inner side wall of the body 1. The guide plate 14 is used to pour the material into the body 1. The bottom of the guide plate 14 is fixedly connected to a spring 15. The other end of the spring 15 is fixedly connected to the inner side wall of the body 1. The spring 15 can flip the guide plate 14 during the movement of the pressing plate 12. The spring 15 has an elastic force that can play a role in resetting. The inner side wall of the body 1 is fixedly connected to a slide plate 16. The slide plate 16 facilitates the staff to subsequently remove the filter plate 17 and clean the filter plate 17 for subsequent use. The inner side wall of the slide plate 16 is plugged with a filter plate 17, which is used to filter the wastewater in the mud cake.

[0026] A connected discharge pipe 18 is installed at the bottom of the body 1, and the discharge pipe 18 is used to discharge the mud cake. A valve 19 is installed in the discharge pipe 18, and the valve 19 can open, close or adjust the fluid channel in the body 1. Water tanks 20 are installed on both sides of the body 1, and the water tank 20 and the inner side wall of the body 1 are both provided with a No. 2 water outlet 21. The No. 2 water outlet 21 is used to discharge the waste water in the body 1 through the water tank 20. A visual window is installed on the side of the water tank 20 away from the body 1, and the visual window is convenient for the staff to observe the discharge of the waste water in the water tank 20. A round cover is installed on the other side of the water tank 20 away from the visual window. The surface hinge of the body 1 is connected to the box door 22, and the box door 22 is used for the staff to open it later to repair the parts in the body 1. A warning sign is pasted on the surface of the box door 22, and the warning sign is used to warn the staff not to approach when the body 1 is working.

[0027] The working process of this utility model is as follows:

[0028] The staff pours the material into the material port 13, and then pours the material into the machine body 1 through the guide plate 14. The spring 15 has elastic force and can play a reset role, facilitating the movement of the pressing plate 12 in the machine body 1. The guide plate 14 will not block the operation path of the pressing plate 12. Then the staff starts the hydraulic press 2, and the hydraulic rod 11 drives the pressing plate 12 to press the material in the machine body 1, so as to squeeze out the wastewater in the material.

[0029] After the material is pressed, a mud cake is formed, and in the process of pressing, the water in the material is filtered through the filter plate 17, and finally the waste water is discharged from the No. 2 water outlet 21 into the water storage tank 20. The staff then opens the switch of the valve 19, and the mud cake is discharged through the discharge pipe 18, and finally transported by the conveyor belt 4. Then the mud cake is moved along with the conveyor belt 4 to drive the extrusion wheel 7 to be squeezed again, so as to squeeze out the excess water in the mud cake. At the same time, it can play a shaping function, which is convenient for subsequent storage of the mud cake, avoiding occupying excess space in the storage box 9 and wasting too much storage box 9 to store mud cakes. The water squeezed out of the mud cake is discharged through the No. 1 water outlet 5, and the aperture of the No. 1 water outlet 5 is smaller than the outer diameter of the particles of the mud cake, so the mud cake will not fall from the No. 1 water outlet 5 into the No. 1 cell, and the No. 1 cell 10 in the storage box 9 can store wastewater, and the No. 2 cell can store mud cakes;
