Problems solved by technology

[0004] The purpose of the present invention is to provide a raw material mixing and metering device in the sludge treatment process, which has a simple structure and is easy to install, and can solve the human control error, time-consuming, low efficiency and cost of sewage (silt) sludge treatment existing in the prior art. For advanced problems, through the installation of flow sensors and humidity detectors, real-time control of parameters such as the amount of sewage (silt) sludge, dosing amount, and humidity of sewage (silt) sludge can be realized to ensure the quality of sewage (silt) sludge treatment, and through The return pipe sends the unqualified sludge (silt) back to the mud inlet for reprocessing, which improves the processing efficiency, reduces the burden on workers, and saves costs

Embodiment 1

[0030] A raw material mixing and metering device in the sludge treatment process, comprising a mixing bin 1, a mud inlet pipe 2, a drug dosing pipe 5, and a mud outlet pipe 8, the mud inlet pipe 2 is connected to the mud inlet 3, and the mud inlet 3 is provided with There is a mud inlet valve 4, and the drug feeding pipe 5 is provided with a drug feeding valve 6, which is characterized in that, the mud inlet 3 and the drug feeding pipe 5 are respectively provided with a flow sensor 7; There is a humidity detector 9 and a mud outlet valve 10. The mud outlet pipe 8 is located above the mud outlet valve 10 and communicates with one end of a return pipe 11, and the other end of the return pipe 11 is connected with the mud inlet pipe 2. The return pipe 11 is provided with a return valve 12 and a return pump 13 in sequence; the mud inlet valve 4, the dosing valve 6, the flow sensor 7, the humidity detector 9, the mud outlet valve 10, the return valve 12, the return The pumps 13 are ...

Embodiment 2

[0033] The raw material mixing and metering device in the sludge treatment process of this embodiment is a further improvement of the first embodiment, the difference is that a pre-mixing bin is provided between the mud inlet 3 and the mud inlet pipe 2, and the pre-mixing bin A stirring device is provided, and the mud inlet 3 is located above the mud inlet valve 4 and a humidity detector 15 is provided.

[0034] When in use, if the moisture content of the sludge (silt) at the 8 outlet pipes is greater than 50%, the measurement and control device 14 controls the return valve 12 and the return pump 13 to open successively, and the sludge (silt) whose humidity value does not meet the standard is returned to the pre-mixing bin , and mix the sewage (silt) mud and the return sewage (silt) mud at the mud inlet pipe 2 through the stirring device in the pre-mixing chamber, and after mixing, the humidity detector 15 at the mud inlet 3 measures the mixed dirt (silt) ) mud humidity, the m...

Abstract

The invention discloses a mixed metering device for raw materials in a sludge treatment process. Flow sensors are respectively arranged on a sludge inlet and a dosing pipe of the device; a humidity detector and a sludge outlet valve are sequentially arranged on a sludge outlet pipe; the sludge outlet pipe is positioned above the sludge outlet valve and is communicated with one end of a reflux pipe; the other end of the reflux pipe is communicated with a sludge inlet pipe; a reflux valve and a reflux pump are sequentially arranged on the reflux pipe. The mixed metering device disclosed by the invention has a simple structure and is convenient to operate; the problems of artificial control errors, long consumed time, low efficiency, high cost and the like of sludge treatment in the prior art can be solved; through the arrangement of the flow sensors and the humidity detector, real-time control of parameters such as sludge entrance quantity of the sludge, dosing amount and sludge humidity can be realized, and the treatment quality of the sludge is ensured; through the sludge reflux pipe, sludge which cannot reach the standard is subjected to reflux retreatment, so that the working efficiency is improved, the burden of workers is reduced, the labor force is saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a raw material mixing and metering device in the sludge treatment process. Background technique [0002] At present, in the field of sewage and river and lake bottom sludge treatment, when dewatering sludge or river and lake silt, it is usually dehydrated in batches, that is, a certain amount of sewage (silt) mud with a certain humidity is pumped into the mixing bin, and the chemical is added. After stirring and dehydrating for a certain period of time, the sewage (silt) sludge is discharged and enters the subsequent production and utilization stage. There are the following problems in this sewage (silt) sludge treatment method: 1. To process the sewage (silt) sludge in batches, it is necessary to wait for the treated sewage (silt) sludge in the mixing bin to be completely discharged before carrying out the follow-up process. Sludge (silt) sludge treatment takes a long ...
