Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sludge moisture content, in particular to a deep dewatered sludge moisture content detection device. BACKGROUND

[0002] Sludge moisture content detection is an important indicator for judging and evaluating sludge dewatering effect. The sludge cake after deep dewatering and pressing is generally hard, and the existing technology generally detects the moisture content by randomly taking a sample from the sludge cake.

[0003] However, both sample taking and detection are manually performed, which requires a large amount of manpower to operate, and the moisture content of sludge at different thicknesses is different, so it is difficult to directly measure the moisture content of sludge at different thicknesses by the existing technology, which can only be completed by manual operation with measuring tools, resulting in poor detection efficiency and effect of sludge. SUMMARY

[0004] In order to improve the detection efficiency and effect, the present application provides a deep dewatered sludge moisture content detection device.

[0005] The deep dewatered sludge moisture content detection device provided by the present application adopts the following technical scheme:

[0007] A detection seat slidingly arranged on the sliding seat;

[0008] A lifting assembly arranged on the sliding seat and used for driving the detection seat to move;

[0009] A connecting pipe arranged on the detection seat;

[0010] A detection head rotatably arranged on the connecting pipe, wherein the detection seat moves to drive the detection head to approach or move away from the sludge and extend into the sludge;

[0011] A protective sleeve arranged on the detection seat, wherein the detection head is located in the protective sleeve, and an inner side wall of the protective sleeve and an outer side wall of the detection head form a feeding cavity in communication with the connecting pipe and for feeding sludge;

[0012] A rotating assembly arranged on the detection seat and used for driving the detection head to rotate;

[0013] An absorption detection assembly is arranged on the detection seat and communicates with the connecting pipe and is used for absorbing sludge for detection.

[0014] By adopting the above technical scheme, the driving assembly drives the sliding seat and the detection mechanism to move, then the lifting assembly drives the detection seat and the detection head to move downward to approach the sludge, and the rotating assembly drives the detection head to rotate, so that the protective sleeve first presses on the sludge, and then the detection head contacts the sludge, the detection head rotates to make the sludge broken and enter the feeding cavity, so that the protective cover and the detection head move downward at the same time, when reaching the specified position, the absorption detection assembly drives the broken sludge to be absorbed for detection, and then continues to move to detect the water content of the sludge at different positions, thereby improving the detection efficiency and effect.

[0015] Meanwhile, the rotation of the detection head breaks the sludge, and also reduces the probability of sludge blockage in the feeding cavity, thereby further improving the detection efficiency and effect; and the protective cover blocks the broken sludge, thereby reducing the pollution of sludge splashing to the environment, so as to realize environmental protection.

[0016] Optionally, the lifting assembly comprises:

[0017] A lifting lead screw is rotationally arranged on the sliding seat and is in threaded connection with the detection seat;

[0018] A lifting motor is arranged on the sliding seat and an output shaft thereof is connected with the lifting lead screw.

[0019] By adopting the above technical scheme, the lifting motor drives the lifting lead screw to rotate, and the lifting lead screw drives the detection seat to move upward and downward.

[0020] Optionally, the rotating assembly comprises:

[0021] A first gear is arranged on the detection head;

[0022] A rotating motor is arranged on the detection seat and extends into the protective sleeve;

[0023] A second gear is arranged on an output shaft of the rotating motor and is in meshing connection with the first gear.

[0024] By adopting the above technical scheme, the rotating motor drives the second gear to rotate, and the second gear drives the first gear and the detection head to rotate, so as to realize that the rotating motor drives the detection head to rotate.

[0025] Optionally, the detection seat is provided with a protective cover, and the first gear and the second gear are located in the protective cover.

[0026] The protective cover blocks the sludge, reduces the probability of the sludge moving to the first gear and the second gear, and improves the stability of the rotating assembly when driving the detection head to rotate.

[0027] Optionally, a spiral shredding piece is fixedly installed on the outer sidewall of the detection head, the shredding piece is used for breaking the sludge and guiding the sludge into the feeding cavity.

[0028] By adopting the above technical scheme, the shredding piece is used for shredding the sludge, thereby reducing the resistance of the detection head moving downward, reducing the stability of the detection device during operation, and saving energy.

[0029] Optionally, an absorption cavity is formed in the protective sleeve and communicates with the connecting pipe, a material suction opening is formed in the protective sleeve and communicates with the absorption cavity and the feeding cavity, and a control assembly is arranged on the absorption cavity and used for controlling the opening and closing of the material suction opening.

[0030] By adopting the above technical scheme, when the detection head and the protective cover move downward, the sludge enters the feeding cavity, and therefore the sludge entering later is located at the bottom end of the protective sleeve. When the detection head and the protective cover move downward to a specified height, the absorption detection assembly opens the suction to absorb the sludge, and the control assembly controls the material suction opening to be opened. The sludge located at the bottom end of the protective sleeve moves to the absorption detection assembly through the material suction opening, the absorption cavity and the connecting pipe for detection. When the absorption detection assembly closes the suction, the control assembly controls the material suction opening to be closed.

[0031] Therefore, the position of the sludge absorbed can be known according to the position of the bottom end of the protective cover, thereby improving the convenience of controlling the position of the sludge. The absorption detection assembly and the control assembly are linked at the same time, thereby further improving the accuracy of the position of the sludge absorbed during detection, improving the detection efficiency and effect.

[0032] Optionally, the control assembly comprises:

[0033] A sliding ring is slidably arranged on the absorption cavity and divides the absorption cavity into a first chamber and a second chamber which are independent of each other, and the second chamber communicates with the material suction opening.

[0034] A material blocking plate is arranged on the sliding ring and used for blocking the material suction opening.

[0035] A spring is arranged on the sliding ring and connected with the absorption cavity to make the material blocking plate block the material suction opening.

[0036] The first pipe body and the second pipe body are arranged on the connecting pipe, the first pipe body is communicated with the first chamber, and the second pipe body extends into the second chamber through the sliding ring and is in sliding connection with the sliding ring.

[0037] By adopting the technical scheme, when the absorption detection assembly starts to absorb sludge, the first pipe body and the second pipe body are subjected to air suction, so that the sliding ring moves under the air suction of the first pipe body, the movement of the sliding ring drives the blocking plate to move and open the material suction opening, and the air suction of the second pipe body causes the sludge to enter the absorption chamber, and then the sludge is moved to the absorption detection assembly through the second pipe body and the connecting pipe for detection. When the absorption detection assembly stops absorbing, the sliding ring moves back under the action of the spring, and the movement of the sliding ring drives the blocking plate to close the material suction opening. Therefore, the opening and closing of the material suction opening are controlled by starting and stopping of the absorption detection assembly, thereby improving the synchronization of the absorption detection assembly and the opening and closing of the material suction opening, further improving the detection accuracy and detection effect, and without the need for other power sources to drive, thereby achieving energy saving and environmental protection.

[0038] Optionally, the absorption detection assembly comprises:

[0040] The moisture sensor is arranged in the connecting pipe and is used for detecting the moisture of the sludge, and the connecting pipe is provided with a collecting assembly through which gas passes and is used for collecting the sludge after detection.

[0041] By adopting the technical scheme, the absorption pump is started to cause the sludge to enter the connecting pipe, so that the sludge is moved to the moisture sensor for detection, then the sludge is moved to the collecting assembly for collection, and then the detection is continuously performed. Therefore, continuous detection of the sludge can be realized, the sludge for the previous detection does not interfere with the sludge for the next detection, and the detection of the next time can be realized immediately after the completion of the previous detection without stopping, thereby improving the detection efficiency and effect.

[0042] Optionally, the sliding seat is provided with a mounting pipe which is communicated with the connecting pipe and is arranged vertically downward, the absorption pump is communicated with the bottom end of the mounting pipe, and the collecting assembly is arranged on the mounting pipe.

[0043] By adopting the technical scheme, the sludge can fall to the collecting assembly for collection under the action of gravity, thereby improving the collection effect of the sludge.

[0044] Optionally, the collecting assembly comprises

[0045] The collecting frame is arranged on the mounting pipe in a sliding manner.

[0046] A collecting plate is arranged on the collecting frame and is abutted on the installation pipe to be positioned, and the moisture sensor is arranged on the collecting plate.

[0047] By adopting the above technical scheme, the sludge is moved to the moisture sensor for detection, and then the sludge falls into the collecting frame under the action of gravity for collection, and the collecting assembly is moved before the sludge at the next position is detected, so that the sludge in the collecting frame tends to be horizontal due to the movement, thereby improving the collection effect of the collecting frame; when cleaning is needed, the collecting plate is pulled to remove the collecting frame for cleaning, and after cleaning, the collecting frame is slid to be installed on the installation pipe, and the collecting plate is abutted on the installation pipe to be positioned, and the moisture sensor can also be replaced after the collecting frame is removed, thereby improving the convenience of replacing the moisture sensor.

[0048] In summary, the present application has at least one of the following beneficial technical effects:
