Description

Technical Field

[0001] This utility model relates to the field of mud-water separation technology, specifically to a mobile mud-water separation and mud cake pressing device. Background Technology

[0002] Sludge-water separation refers to a series of treatment steps that gradually separate water containing impurities such as silt, suspended solids, and organic matter to obtain clean water. This method is commonly used to treat sewage, rivers, lakes, and sludge-water from construction projects. Sludge-water separation can effectively improve water resource utilization and reduce environmental pollution, playing a vital role in protecting water resources and improving the ecological environment.

[0003] The main steps of mud-water separation generally include: 1. Preliminary screening: The water containing impurities is initially filtered using physical methods such as a mesh screen to remove larger particles. 2. Sedimentation: The initially filtered water is allowed to stand for a period of time, allowing heavier impurities to settle to the bottom. 3. Overflow: The upper layer of clear water is slowly allowed to flow out to avoid carrying away impurities from the bottom. 4. Further sedimentation: The above-mentioned clear water is allowed to settle again for a period of time to remove fine suspended solids and organic matter. 5. Filtration: The water is further filtered using equipment such as filters to remove residual impurities. 6. Disinfection: The treated water is disinfected to ensure that it meets safety and hygiene standards.

[0004] In actual production, due to limitations of on-site equipment, the above steps can be simplified to centrifugation and filter press. However, there is currently a lack of equipment that uses centrifugation and filter press as the main means of mud-water separation and mud cake pressing, especially equipment with high mobility.

[0005] CN207276479U provides a mobile automated sludge rapid dewatering device, comprising at least: a coagulation system, a dosing system, a clarifier, and a dewatering system. It highly integrates dosing, flocculation, sludge-water separation, deep sludge dewatering, and water purification processes, achieving a unified effect. Compared to traditional treatment methods and simple mechanical dewatering, it not only achieves rapid sludge-water separation and good dewatering effect, but also has a small footprint and a high degree of automation. Especially with a container as the carrier, the structure is more compact and occupies less space. Flexible selection of vehicle or ship mounting methods allows for mobility tailored to river characteristics. Combined with ultrafiltration membranes for deep purification of effluent, it eliminates secondary pollution of the effluent. However, it lacks a proper disposal method for the sludge cake.

A pressing belt 6 is provided above the second filter cloth 5 and rotated by two third rotating shafts 61.

The front end of the first filter cloth 4 passes through the slot 11 provided on the upper plate 1. A guide plate 7 is provided at the rear end of the first filter cloth 4.

[0029] The upper plate 1 and the lower plate 2 are connected by three sets of symmetrical first fixing rods 9. The inner sides of the latter two sets of first fixing rods 9 are rotatably connected to the second rotating shaft 51 and the third rotating shaft 61, respectively. The first fixing rod 9 in the middle is equipped with a first drive motor 91 and a second drive motor 92 for driving the second rotating shaft 51 and the third rotating shaft 61 to rotate, respectively.

[0030] The first filter cloth 4 is driven to rotate by two first rotating shafts 41. The upper plate 1 has two sets of symmetrical second fixing rods 12 on the front and rear sides. The two sets of second fixing rods 12 are rotatably connected to the two first rotating shafts 41 respectively. A third drive motor 13 for driving the first rotating shaft 41 to rotate is provided on one of the second fixing rods 12 at the front end. The first rotating shaft 41 at the rear end extends 20cm beyond the rear end of the upper plate 1.

[0031] The rear end of the lower plate 2 is fixedly connected to the bottom of the guide plate 7 via a connecting rod 22. The upper surface of the front end of the lower plate 2 is provided with an inclined plate 23 for receiving mud cakes. The inclined plate 23 is aligned with the front end of the second filter cloth 5.

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 is that:

[0036] The upper end of the drainage ditch 8 extends 10cm beyond the upper end of the upper slab 1 and the lower slab 2.

[0037] Example 3

[0039] The first pivot 41, located at the rear end, extends 30cm beyond the rear end of the upper plate 1.

[0040] Working principle:

[0041] The working principle of a mobile mud-water separation and mud cake pressing device of this utility model is briefly described below.

[0042] When in use, the water-containing sludge is first injected into the centrifuge cylinder 3. After centrifugation, the dewatered sludge is separated and introduced above the first filter cloth 4 for gravity sedimentation. The third drive motor 13 is turned on to drive the first rotating shaft 41 to rotate, so that the first filter cloth 4 moves the sludge backward. The filtered water falls on the upper surface of the upper plate 1 and is collected and discharged through the drainage channels 8 on both sides.

[0043] When the sludge moves to the upper end of the first filter cloth 4, it falls and, under the action of the guide pump 7, falls between the second filter cloth 5 and the pressing belt 6. The first drive motor 91 and the second drive motor 92 are turned on, which respectively drive the second rotating shaft 51 and the third rotating shaft 61 to rotate, thereby driving the second filter cloth 5 and the pressing belt 6 to rotate. At this time, the first filter cloth 4 cooperates with the second filter cloth 5 to press and filter the sludge under the action of the pressing belt 6. The filtered water falls on the upper surface of the lower plate 2 and is collected and discharged through the drainage channels 8 on both sides. The pressed sludge cake is discharged from the end of the second filter cloth 5 and discharged through the inclined plate 23 to other equipment for collecting sludge cake.
