Abstract
The invention discloses a chemical dosing device used during sludge dewatering. The device is connected with a sludge dewatering stirrer and comprises a chemical guiding pipe installed in the sludge dewatering stirrer, wherein an upper port of the chemical guiding pipe is located above the liquid level of the sludge dewatering stirrer, a chemical dosing pipe is arranged outside the sludge dewatering stirrer, and a chemical outlet of the chemical dosing pipe is located above the upper port of the chemical guiding pipe. According to the device, chemical is added to the sludge dewatering stirrer through the chemical dosing pipe and flows into the corresponding chemical guiding pipe, and the chemical guiding pipe can convey chemical liquid to the bottom of the sludge dewatering stirrer to be mixed with sludge; in this way, even if a sudden halt occurs, sludge and chemical mixing liquid can not be sucked back into the chemical dosing pipe due to the fact that the chemical guiding pipe does not make direct contact with the chemical dosing pipe and a gap preventing reverse sucking is formed between the chemical guiding pipe and the chemical dosing pipe, and then blocking of the chemical dosing pipe is prevented; furthermore, sludge and chemical mixing liquid can also be prevented from being guided into a chemical dosing system, so that the safety of the chemical dosing system is guaranteed.
Description
Technical field
The present invention relates to a kind of device for dehydrating sladge waste technical field, particularly relate to a kind of sludge dewatering chemicals dosing plant.
Background technology
The PAM chemical feed pipe wire system used in sludge dewatering production process is one of important treatment system.This system is provided with the chemical feed pipe extended to bottom sludge agitation pond, because chemical feed pipe extend into the bottom in sludge agitation pond, therefore in process of production once there is power failure phenomenon, because equipment is out of service suddenly, negative pressure can be formed in chemical feed pipe, mud medicine mixed solution near the mouth of pipe of chemical feed pipe will be back in chemical feed pipe, repeatedly have a power failure in long-time power failure or life-time service process, chemical feed pipe just can block by mud medicine mixed solution, after blocking chemical feed pipe, chemical feed pipe flow can be made to reduce, even also can affect the normal operation of PAM chemical feed pipe wire system, because this increasing the parking rate of equipment, reduce the efficiency of sludge dewatering, also add the workload of maintenance personnel simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sludge dewatering chemicals dosing plant that can prevent mud medicine mixed solution from flowing backwards, blocking.
For solving the problems of the technologies described above, technical scheme of the present invention is: sludge dewatering chemicals dosing plant, be connected with sludge dewatering agitator, comprise the medicine-introducing pipe be installed in described sludge dewatering agitator, the upper port of described medicine-introducing pipe is positioned at more than the liquid level of described sludge dewatering agitator, be provided with chemical feed pipe outside described sludge dewatering agitator, the medicine outlet of described chemical feed pipe is positioned at above the upper port of described medicine-introducing pipe.
As preferred technical scheme, the inwall of described sludge dewatering agitator is furnished with fixed support, and described medicine-introducing pipe is connected with described fixed support.
As the improvement to technique scheme, described medicine-introducing pipe is set to standpipe.
Owing to have employed technique scheme, sludge dewatering chemicals dosing plant, be connected with sludge dewatering agitator, comprise the medicine-introducing pipe be installed in described sludge dewatering agitator, the upper port of described medicine-introducing pipe is positioned at more than the liquid level of described sludge dewatering agitator, be provided with chemical feed pipe outside described sludge dewatering agitator, the medicine outlet of described chemical feed pipe is positioned at above the upper port of described medicine-introducing pipe, the invention has the beneficial effects as follows: at the top of sludge dewatering agitator, agitator motor is installed, agitator motor is connected with the stir shaft be arranged in sludge dewatering agitator, when stirring, the mud of sludge dewatering agitator bottom forms centrifugal force, make the mud in medicine-introducing pipe emptying under the effect of stirring, now in sludge dewatering agitator, add medicine by chemical feed pipe, medicine flows in the corresponding medicine-introducing pipe arranged, the bottom that liquid can be conveyed into sludge dewatering agitator by medicine-introducing pipe mixes with mud, like this, even if there is the phenomenon of shutting down suddenly, because medicine-introducing pipe does not directly contact with chemical feed pipe, be formed with the gap of anti-suck between the two, mud medicine mixed solution also can not by suck-back in chemical feed pipe, thus prevent the obstruction of chemical feed pipe, mud medicine mixed solution can also be prevented to be directed in medicine system, thus ensure that the safety of medicine system.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the present invention and explain, not delimit the scope of the invention.Wherein:
Fig. 1 is the structural representation of the embodiment of the present invention;
In figure: 1-sludge dewatering agitator; 2-medicine-introducing pipe; 3-chemical feed pipe; 4-fixed support; 5-agitator motor; 6-stir shaft.
Embodiment
Below in conjunction with drawings and Examples, set forth the present invention further.In the following detailed description, the mode only by illustrating describes some one exemplary embodiment of the present invention.Undoubtedly, those of ordinary skill in the art can recognize, when without departing from the spirit and scope of the present invention, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
As shown in Figure 1, sludge dewatering chemicals dosing plant, be connected with sludge dewatering agitator 1, comprise the medicine-introducing pipe 2 be installed in described sludge dewatering agitator 1, the upper port of described medicine-introducing pipe 2 is positioned at more than the liquid level of described sludge dewatering agitator 1, be provided with chemical feed pipe 3 outside described sludge dewatering agitator 1, the medicine outlet of described chemical feed pipe 3 is positioned at above the upper port of described medicine-introducing pipe 2.
The inwall of described sludge dewatering agitator 1 is furnished with fixed support 4, and described medicine-introducing pipe 2 is connected with described fixed support 4, and described medicine-introducing pipe 2 is set to standpipe, the liquid added directly can be delivered to the bottom of described sludge dewatering agitator 1.Be provided with agitator motor 5 at the top of sludge dewatering agitator 1, agitator motor 5 is connected with the stir shaft 6 be arranged in sludge dewatering agitator 1.
The method of work of embodiment and effect are:
When stirring, due to the effect of described stir shaft 6, make the mud fast rotational of described sludge dewatering agitator 1 bottom and form centrifugal force, make the mud in described medicine-introducing pipe 2 emptying under the effect of stirring, now in described sludge dewatering agitator 1, add medicine by described chemical feed pipe 3, first medicine flows in the corresponding described medicine-introducing pipe 2 arranged, liquid can be directly delivered to the bottom of described sludge dewatering agitator 1 and fully mix with mud by described medicine-introducing pipe 2, like this, even if there is the phenomenon of shutting down suddenly, due to the setting in described anti-suck gap, mud medicine mixed solution also can not by suck-back to described chemical feed pipe 3, thus prevent the obstruction of described chemical feed pipe 3, mud medicine mixed solution can also be prevented to be directed in medicine system, thus ensure that the safety of whole medicine system.
