Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a dry powder type sludge conditioner dosing device. Background Art

[0002] Sludge is a solid waste generated during sewage treatment. It contains a large amount of organic matter, heavy metals and other harmful substances. If not handled properly, it will cause serious pollution to the environment. Sludge conditioning is an important part of the sludge treatment process. The types of sludge conditioners currently available on the market are mainly dry powder and liquid types. Among them, dry powder conditioners have the advantages of easy storage, convenient packaging and transportation, and low corrosion to dosing equipment. However, dry powder sludge conditioners are usually hygroscopic, easy to agglomerate and cause equipment blockage, or due to production process and raw material problems, there are lumps of different sizes in the dry powder, and it is not easy to disperse during the addition process, which reduces the effect of sludge conditioning.

[0003] In the prior art, dry powder sludge conditioners can be efficiently transported by positive pressure or negative pressure pneumatic force. However, at the end of the conditioner addition, since the inlet is located at the top of the sludge conditioning tank, moisture can easily enter the equipment through the inlet. In addition, the hygroscopicity of the dry powder conditioner can easily cause the conditioner to agglomerate and the equipment inlet to be blocked, affecting the normal production of sludge treatment. In addition, if the dry powder conditioner is added by continuous direct injection or intermittent addition into the sludge conditioning tank through a pipeline, the conditioner will fall onto the sludge surface in a clumping state. In addition, due to the high viscosity of the sludge, and considering factors such as power and tank stability, it is difficult to achieve high-speed rotation of the stirring mechanism in large-scale sludge conditioning mixing tanks (volume greater than 50 cubic meters) in actual production (the designed stirring speed is generally lower than 60 rpm). Under this working condition, it is very easy for the conditioning agent to clump together to form "lumps" and be difficult to mix evenly with the sludge, resulting in a large amount of undissolved conditioning agent "powder clumps" or "lumps" in the conditioned sludge, causing waste and ineffective loss of the conditioning agent, and reducing the sludge conditioning effect.

[0025] The effect achieved by the entire embodiment 1 is that when the device is used to add dry powder conditioner to the sludge conditioning tank, the dry powder conditioner is first transported to the treatment box 1 by wind power, and then the driving motor 201 is started to drive the first pulley 202 and the second pulley 203 to rotate. When the first pulley 202 rotates, it cooperates with the first transmission belt 204 to drive one of the rolling rollers 301 to rotate. At this time, the rolling roller 301 will drive the other rolling roller 301 to rotate in the opposite direction under the action of the two transmission gears 302, so as to roll the dry powder conditioner that passes through and crush the agglomerated conditioner.

[0027] The effect achieved by the entire embodiment 2 is that when the dry powder conditioner is impacted into powder, it will fall out from the bottom of the processing box 1.

By setting the flap 403, the rolled dry powder conditioner is stored in the processing box 1. When it is needed to be added for use, the servo motor 401 is started to drive the rotating shaft 402 to rotate. At this time, the flap 403 on the surface of the rotating shaft 402 will rotate from a horizontal state to a vertical state, so that the dry powder conditioner in the processing box 1 is discharged.

[0028] Working principle: When the device is used to add dry powder conditioner to the sludge conditioning tank, the dry powder conditioner is first transported to the treatment box 1 by wind power. At this time, the driving motor 201 is started to drive the first pulley 202 and the second pulley 203 to rotate. When the first pulley 202 rotates, it cooperates with the first transmission belt 204 to drive one of the rolling rollers 301 to rotate. At this time, the rolling roller 301 will drive the other rolling roller 301 to rotate in the opposite direction under the action of the two transmission gears 302, so as to roll the dry powder conditioner that has passed through and crush the agglomerated conditioner. When the rolled dry powder conditioner falls downward, the second pulley 203 cooperates with the second transmission belt 207 drives the fourth pulley 206 to rotate at high speed, and the fourth pulley 206 will drive the roller 208 to rotate at high speed. When the roller 208 rotates at high speed, the impact rod 209 on its surface cooperates with the fixed rod 15 on the inner wall of the processing box 1 to violently impact the passing dry powder conditioner, and completely break it up and disperse it, thereby avoiding the formation of "powder clumps" or "lumps" of conditioner when the dry powder conditioner falls to the surface of the conditioned sludge and affects the sludge conditioning effect. When the dry powder conditioner is impacted and becomes powdery, it will fall out from the bottom of the processing box 1. At this time, starting the high-speed fan 14 can easily blow the powdered dry powder conditioner into the sludge conditioning tank, which is easy to operate and has high practicality.
