Technical Field

[0001] The utility model relates to the technical field of mud feeding devices, in particular to a mud feeding device for heating and drying equipment. Background Art

[0002] At present, the disposal of sludge in big cities has become difficult and expensive. Long-distance sludge hauling, rising fuel and transportation costs, sludge landfill consumes a lot of land resources and the cost is rising. The direct incineration of wet sludge is expensive, and citizens oppose the construction of incinerators in the city. Sludge thermal drying is a safe, reliable, fast, efficient and large-scale sludge reduction technology. Sludge drying refers to the process of removing most of the water content from sludge through percolation or evaporation. After sludge is thermally dried, the following effects can be achieved: the sludge is dried from 25% DS to 90% DS, the weight is reduced by about 78%, the product is easy to post-process, and energy and material recycling can be carried out. The possibility of harmful substances returning to the environment is reduced to a minimum. The sludge drying equipment uses the hot air generated by coal or other exhaust gas devices as the drying heat source to dry the sludge in the drying furnace.

[0003] During the sludge treatment process, the sludge needs to be filtered and dried to make a mud cake. The sludge is not removed thoroughly enough and contains solid impurities. For example, riverbed sludge contains stones, broken glass and other impurities. If these impurities are not removed, it will not only damage the equipment but also affect the efficiency of sludge treatment. When the sludge is fed directly, the sludge will form lumps. When it is thick, the inner cavity may not be easy to dry and contain moisture. For this reason, we propose a sludge feeding device for heating and drying equipment. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mud feeding device of a heating and drying equipment, comprising a lifting bracket, a loading trough is installed at the top of the lifting bracket, a column bracket is arranged on the right side of the lifting bracket, a filter screen is installed on the column bracket, a vibrator is installed at the top of the filter screen, a compactor is installed at the lower end of the filter screen, a conveyor belt is installed at the bottom end of the compactor, and a limited layer device is installed in the middle of the top surface of the conveyor belt.

[0006] Preferably, the inner cavity of the charging trough is sloped, a control switch is installed on the side wall of the lifting bracket, and the lifting bracket is hydraulically lifted.

[0007] Preferably, the outlet of the charging trough is connected to the inlet of the filter screen, and the outlet of the compactor is connected to the inlet of the conveyor belt.

[0009] Preferably, the filter screen comprises: a feed bin and a screen, wherein the screen is detachably mounted in the middle of an inner cavity of the feed bin, and a hole is provided on the bottom surface of the feed bin.

[0010] Preferably, a driving motor is installed on the side wall of the compactor, and the output shaft of the driving motor passes through the side wall of the compactor and is connected to a roller shaft, and the other end of the roller shaft is rotatably connected to a base, and the base is installed on the inner cavity side wall of the compactor.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1) When the sludge is fed in, the device is equipped with a filter screen, which can effectively remove impurities in the sludge, thereby improving the efficiency in the later drying process. A vibrator is installed on the filter screen, and when the sludge blocks the screen, the vibrator vibrates, and the sludge in the mesh is shaken off, making the sludge feeding smoother. The device has a simple structure and is easy to use.

[0013] 2) A compactor is set at the lower end of the filter screen. The compactor is squeezed by rollers. Some sludge can be pressed into a flat shape. In the later drying, it is not easy for the sludge to be mixed with water. The compactor can also divert the sludge. When the sludge is fed in, a large amount of sludge will not fall at one time, forming accumulation and causing incomplete drying later.

[0014] 3) When the sludge is fed in, a layer limiting device is installed on the conveyor belt. In order to prevent the internal sludge from being too thick and mixed with water in the inner cavity, the scraper can scrape off the extra-high sludge to limit the thickness.
