Technical Field
[0001] The utility model relates to the field of sludge treatment, in particular to a sludge treatment device. Background Art
[0002] Silt is a soft soil with a natural water content greater than the fluidity limit and a porosity greater than 1.5. It is a modern sediment formed under the conditions of slow water flow in bays, lakes or river bays with the participation of microorganisms. It is rich in organic matter, often gray-black in color, with low mechanical strength and strong compressibility.
[0003] When too much silt accumulates in the river, it will cause the water in the river to overflow. Therefore, personnel are needed to clean the river regularly to avoid blockage or water overflow.
[0004] However, in daily life, as the pollution of urban rivers becomes more and more serious, a large amount of domestic garbage will be mixed in the silt in the river. For example, common plastic bags, packaging bags, etc., these domestic garbage will gradually sink under common accumulation and eventually mix with the silt in the river. In addition, there are many heavy metals and metal-like items in the river, which will cause the machine to be damaged easily due to the influence of metal and domestic garbage during the dehydration operation of the silt, such as metal stuck inside the machine, causing the machine to be unable to rotate, or the screw inside the dehydrator is entangled with too much domestic garbage, resulting in a decrease in the dehydration effect.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] As shown in the figure, this embodiment provides a sludge treatment device, including a bottom plate 1, a vertical pole is fixedly installed near the corner of the bottom plate 1, the top of the pole is an L-shaped structure, and a crushing box 2 is fixedly installed on the inner side of the pole, and the pole is fixedly installed on the outer shell of the crushing box 2, so that the crushing box 2 can be located above the bottom plate 1, as shown in FIG. Figure 1 The lower end of the crushing box 2 is fixedly connected to a stacking dehydrator 6 by a pipeline (the model of the stacking dehydrator 6 is specifically referred to as D1-301).
[0024] Two crushing wheels 33 are rotatably installed inside the crushing box 2, wherein one end of the two crushing wheels 33 extends to the outside of the crushing box 2, a driving gear 31 is fixedly installed on one end of the outer side of one crushing wheel 33, and a driven gear 32 is fixedly installed on one end of the other crushing wheel 33.
[0025] The driving gear 31 meshes with the driven gear 32, and the other end of the driving gear 31 is connected to the motor 3 (the output shaft of the motor 3 is fixedly connected to the driving gear 31, and a support plate is fixedly installed on the outer side of one end of the crushing box 2, and the motor 3 is fixedly installed on the support plate, such as Figure 1 As shown in the figure, the output shaft of the motor 3 can rotate with the driving gear 31, and when the driving gear 31 rotates, the driven gear 32 can be driven to rotate in the opposite direction, so that the crushing wheel 33 fixedly connected to the driving gear 31 and the driven gear 32 can move synchronously, so that the two crushing wheels 33 move in different directions, and the crushing wheel 33 can crush the metal entering the crushing box 2, so that the metal can be mixed with the diluted sludge after crushing, so as to prevent the metal from being stuck in the stack dehydrator 6 in the subsequent mixing operation, and to prevent the metal from stopping the machine from working or damaging the machine, as shown in the figure. Figure 2 shown.
[0026] A filter grille 5 is installed inside the crushed material box 2. Hanging buckles are fixedly installed at both ends of the filter grille 5. The top of the hanging buckle is an "L"-shaped structure. The upper end of the crushed material box 2 is open, and a groove is opened on the corresponding side so that the hanging buckle can be inserted into the inside of the groove. Figure 2 As shown. Under the action of the hook and the groove, the filter grille 5 can be prevented from moving. Under the action of the filter grille 5, garbage in life can stay on the filter grille 5, such as plastic bags, packaging bags and other products in life, to prevent plastic bags and packaging bags from entering the inside of the crushing box 2 (because plastic bags, packaging bags and other products are flexible products with extensibility. After entering the inside of the crushing box 2, the crushing wheel 33 may not be able to damage them. Once plastic bags, packaging bags and other products enter the stacked dehydrator 6, the products will entangle or block the filter tank, thereby reducing the efficiency of the stacked dehydrator 6).
[0027] In the process of using the filter grille 5, it can be installed according to the actual situation on site. For example, the filter grille 5 can be tilted to facilitate the removal of domestic garbage.
[0028] A material pipe 4 is installed on the top opening edge of the crushing box 2 , and a plurality of water spray nozzles are fixedly installed on the circumferential surface of the material pipe 4 . The water spray nozzles are in an inclined state and can spray water toward the filter grid 5 .
[0029] One end of the material pipe 4 is fixedly connected to the external flocculant and water source material box, and a water pump is used to transport the water source with the flocculant to the water nozzle. Under the action of the water nozzle, the block sludge can be diluted so that the sludge can flow into the inside of the crushing box 2. Under the action of the flocculant, the diluted sludge can be separated into liquid and soil under the action of the stacked dehydrator 6, thereby realizing the dehydration operation.
[0030] Its working principle is as follows: when in use, the block sludge is placed above the filter grille 5, and then the sludge is diluted under the action of the water nozzle. The diluted reserve will flow into the crushing box 2, and the domestic garbage will remain on the filter grille 5.
[0031] The metal entering the crushing box 2 will be crushed by the crushing wheel 33, and the crushed metal will enter the stacked dehydrator 6 together with the sludge. Under the action of the stacked dehydrator 6, the sludge and the metal are mixed into a cake, thereby completing the treatment of the sludge.
[0032] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments.
