Description

Technical Field

[0001] The utility model relates to the technical field of mud dewatering, in particular to a sand yard mud dewatering integrated machine. Background Art

[0002] When making sand in a sand yard, the mined sand materials need to be washed by a sand washer to remove impurities and silt on the surface of the sand and gravel. A large amount of muddy water will be generated during the sand washing process. In order to facilitate the treatment and transportation of the muddy water, it is necessary to first dehydrate the muddy water and then perform the next step of treatment. In the prior art, the utility model patent with the patent application number 202121464308.3 discloses a mud dewatering device for sewage treatment, which mainly consists of a sewage treatment tank, a feed hopper, a mud filter screen, a separation inner tank, a separation outer tank, etc. When in use, the mud is filtered through the filter screen and then introduced into the separation inner tank for centrifugal separation, so that the water in the mud is discharged through the separation inner tank, and the silt remains in the separation inner tank. Then, the sealed door on the separation inner tank is opened, and the dehydrated silt in the separation inner tank can be taken out.

[0003] The inventor believes that the following problems exist in the use process: when it is necessary to take out the dehydrated silt, the staff still needs to manually take out the dehydrated silt in the separation inner tank, which not only has a large labor intensity but also is inconvenient. Therefore, a mud dewatering machine with an automatic silt discharge function is needed. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a sand yard mud dewatering integrated machine that can automatically discharge the dehydrated silt in the dewatering barrel, facilitating the discharge of silt, having a low labor intensity and high practicability.

It also includes a dewatering barrel, a connecting frame, a sealing cover, a water inlet pipe, a sludge discharging mechanism and a collecting mechanism. The dewatering barrel is fixedly installed on the dewatering tank through the connecting frame. A cavity is arranged in the dewatering barrel. A plurality of groups of filter holes communicated with the cavity are arranged at the lower part of the dewatering barrel. All the plurality of groups of filter holes are located in the chamber of the dewatering tank. A filter cloth is arranged on the inner side wall of the dewatering barrel. The left end of the dewatering barrel is open. The sealing cover is installed at the opening at the left end of the dewatering barrel through bolts. The sealing cover is located on the left side of the dewatering tank. The sludge discharging mechanism is installed on the dewatering barrel and the dewatering tank.

The collecting mechanism is located below the left end of the dewatering barrel. The water inlet pipe is fixedly installed on the dewatering tank. The lower end of the water inlet pipe is communicated with the cavity of the dewatering barrel. When dewatering the mud after sand washing, the mud is conveyed into the water inlet pipe through an external conveying mechanism. Then the mud enters the cavity of the dewatering barrel through the water inlet pipe. The water in the mud passes through the filter cloth and the filter holes on the dewatering barrel and falls to the lower part of the chamber of the dewatering tank. The sludge in the mud remains in the cavity of the dewatering barrel. When it is necessary to discharge the sludge in the dewatering barrel, stop conveying the mud into the water inlet pipe, open the sealing cover, and then push the sludge in the cavity of the dewatering barrel to the left through the sludge discharging mechanism, so that the sludge automatically falls into the collecting mechanism through the opening at the left end of the dewatering barrel for collection.

The input end of the vacuum pump communicates with the upper part of the chamber of the dewatering tank, and an exhaust pipe is provided at the output end of the vacuum pump. When dewatering the slurry in the dewatering bucket, the vacuum pump is turned on to reduce the pressure in the chamber of the dewatering tank, promoting the discharge of water in the cavity of the dewatering bucket and improving the dewatering efficiency of the slurry. When it is necessary to discharge the water in the chamber of the dewatering tank, the valve on the discharge pipe is opened, and the water in the lower part of the chamber of the dewatering tank can be discharged through the discharge pipe.

[0009] Preferably, it further includes a filter screen, which is fixedly installed on the water inlet pipe. Through the above setting, the slurry entering the water inlet pipe first passes through the filtration of the filter screen, and the large-particle solid impurities in the slurry are filtered out by the filter screen, avoiding the blockage of the filter holes on the dewatering bucket by the large-particle solid impurities.

The left end of the dewatering barrel 4 is an opening. The sealing cover 6 is installed at the opening at the left end of the dewatering barrel 4 through bolts. The sealing cover 6 is located on the left side of the dewatering tank 3. The sludge discharging mechanism is installed on the dewatering barrel 4 and the dewatering tank 3 and has a sludge discharging function. The collection mechanism is installed on the bottom plate 1 and is located below the left end of the dewatering barrel 4. The water inlet pipe 7 is fixedly installed on the dewatering tank 3. The lower end of the water inlet pipe 7 communicates with the cavity of the dewatering barrel 4. When dewatering the mud after sand washing, the mud is transported to the water inlet pipe 7 through an external conveying mechanism, and then the mud enters the cavity of the dewatering barrel 4 through the water inlet pipe 7. The water in the mud passes through the filter cloth and filter holes on the dewatering barrel 4 and falls to the lower part of the chamber of the dewatering tank 3. The sludge in the mud remains in the cavity of the dewatering barrel 4. When it is necessary to discharge the sludge in the dewatering barrel 4, stop transporting the mud to the water inlet pipe 7, open the sealing cover 6, and then push the sludge in the cavity of the dewatering barrel 4 to the left through the sludge discharging mechanism, so that the sludge automatically falls into the collection mechanism through the opening at the left end of the dewatering barrel 4 for collection; it can automatically discharge the dehydrated sludge in the dewatering barrel 4, facilitating the discharge of the sludge, with low labor intensity and high practicability.
