Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration, in particular to an ultrasonic dehydration screen for sewage treatment. Background Art

[0002] Sludge is a porous medium with high moisture content. The moisture content of untreated sludge is as high as over 95%.

[0003] Publication No. CN110357394A discloses a device for ultrasonic molecular sieve dehydration of urban sludge. The patent sets an air recoil mechanism above the dehydration drum. The air recoil mechanism includes a recoil pipe arranged along the axial direction of the dehydration drum. The recoil pipe is provided with a plurality of air nozzles pointing to the radial side wall of the dehydration drum. The air recoil mechanism sprays air toward the dehydration drum, which can continuously clear the blockage of the molecular sieve, further accelerate the dehydration of the sludge, and improve the dehydration rate. However, the patent still has the following problems in actual use:

[0004] The air recoil mechanism sprays air toward the dewatering drum, which can continuously clear the blockage of the molecular sieve, further accelerate the sludge dehydration and improve the dehydration rate. However, in actual use, in order to ensure that the air recoil mechanism sprays air at a high velocity, the air flow nozzle is set to be small, which makes the range of the air flow spray small and cannot spray the dewatering drum more comprehensively. If the number of air nozzles is directly increased, although the effect of comprehensive jetting can be achieved, the simultaneous jetting of multiple air nozzles requires a higher pressure on the air pump.

[0005] An ultrasonic dewatering screen for sewage treatment is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an ultrasonic dewatering screen for sewage treatment, so as to solve the problem proposed in the above-mentioned background technology that the air recoil mechanism currently sprays air toward the dewatering drum, which can continuously clear the blockage of the molecular sieve, further accelerate the dewatering of the sludge, and improve the dehydration rate. However, in actual use, in order to ensure that the flow rate of the air recoil mechanism is relatively large, the caliber of the air flow spray is set to be relatively small, so that the range of the air flow spray is relatively small, and the dewatering drum cannot be sprayed more comprehensively. If the number of air nozzles is directly increased, although the effect of comprehensive jetting can be achieved, the problem of high pressure requirements on the air pump for multiple air nozzles to spray at the same time is encountered.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultrasonic dewatering screen for sewage treatment, comprising a bracket;

[0008] A rotating shaft is symmetrically installed on the upper inner side of the bracket, and a drum screen is fixedly installed between the two rotating shafts, and a driving motor is fixedly installed on one side of the outer side of the bracket, and the output end of the driving motor passes through the bracket and is fixedly connected to one side of the rotating shaft, and an ultrasonic generator is arranged on the inner side of the bracket below the two rotating shafts;

[0009] Also includes:

[0010] A mud discharge pipe is connected through one side of the drum screen, a feed pipe is connected through the other side of the drum screen, a drainage rack is connected through the inner side of the bracket, and a discharge hopper is connected through one side of the bracket below the mud discharge pipe;

[0011] Among them, a fixing frame is symmetrically installed on the top of the bracket, and a mounting pipe is fixedly installed between the two fixing frames, and an anti-blocking component is arranged on the top and one side of the drum screen;

[0012] Among them, the anti-blocking component includes a first bevel gear fixedly installed on the outside of a rotating shaft on one side, and a positioning frame is symmetrically installed on one side of a fixed frame, and a rotating rod is rotatably connected between the two positioning frames, and a second bevel gear is fixedly installed on the bottom end of the rotating rod, and the second bevel gear is meshingly connected with the first bevel gear.

[0013] Preferably, a cam is fixedly mounted on the top of the rotating rod, and a movable frame is slidably connected to the outside of the mounting tube, and a movable plate is fixedly mounted below the two movable frames, and the cam is slidably connected to one side of the movable frame.

[0014] Preferably, a telescopic spring is sleeved on one side of the two movable frames outside the mounting tube, and one end of the telescopic spring is fixedly connected to the movable frame, and a fixed block is fixedly installed on the other end of the telescopic spring, and the fixed block is fixedly connected to the mounting tube.

[0015] Preferably, a plurality of telescopic hoses are connected through the bottom of the mounting tube, and a movable tube is connected through one end of the telescopic hose away from the mounting tube, and the bottom end of the movable tube is movably connected to an air outlet pipe via a rotating joint, and the plurality of movable tubes are fixedly connected to the movable plate.

[0016] Preferably, mounting brackets are symmetrically mounted on the rear side of the mounting tube, and a support plate is fixedly mounted on one side of the two mounting brackets.

[0017] Preferably, a plurality of teeth are fixedly mounted on one side of the support plate, and a rotating gear is fixedly mounted on the upper part of the outer portion of the air outlet pipe, and the rotating gear is meshingly connected with the teeth.

[0018] Preferably, one end of the mounting pipe passes through a fixing frame on one side and is connected with a connecting pipe.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the ultrasonic dewatering screen for sewage treatment is provided with anti-blocking components above and on one side of the drum screen, so that when the drum screen is blown to prevent blockage, the blowing range can be expanded, the efficiency of inflation can be improved, and the number of air outlet pipes does not need to be increased, thereby improving practicality. The specific contents are as follows:

[0020] 1. Anti-blocking components are set above and on one side of the drum screen. When dehydrating the sludge, the sludge is introduced into the drum screen through the feed pipe, and then the ultrasonic generator emits ultrasonic waves, and the drive motor is started to drive the rotating shaft to rotate, so that the drum screen rotates, and the sludge is turned over, and dehydration is carried out under the action of ultrasonic waves (the mechanical and cavitation effects of ultrasonic waves themselves are used to destroy the floc structure in the sludge and remove the moisture contained therein). The air compression pump is connected through the connecting pipe, so that the compressed air enters the installation pipe, and then enters the air outlet pipe through the telescopic hose and the movable pipe. After that, the compressed air is ejected through the air outlet pipe, and the drum screen can be blown to prevent blocking. During the rotation process, the rotating shaft passes through the first bevel gear and the second bevel gear. The meshing of the wheels drives the rotating rod to rotate, and the rotating rod drives the cam to rotate after the rotation. After the cam rotates continuously, it can push the movable frame to move through the sliding connection with the movable frame on one side, so that the movable plate can move, and the two movable frames can stretch the telescopic spring during the movement. After the cam rotates one circle, it is reset under the action of the telescopic spring, and then with the continuous rotation of the drum screen, the movable plate can reciprocate, and then it can drive a number of movable pipes to reciprocate, so that the jet range of the outlet pipe can be expanded, and the drum screen can be fully jetted. Through the anti-blocking component, when the drum screen is blown to prevent blockage, the blowing range can be expanded, the inflation efficiency is improved, and the number of outlet pipes does not need to be increased, thereby improving practicality;

[0021] 2. When the movable plate drives several movable tubes to move back and forth, the movement of the movable plate drives the air outlet pipe to move. After the air outlet pipe moves, the external rotating gear can rotate by meshing with the teeth on the support plate, thereby causing the air outlet pipe to rotate. The air outlet pipe can rotate back and forth during the reciprocating movement, thereby further expanding the jet range of the air outlet pipe and further improving the anti-blocking efficiency.

[0030] A cam 205 is fixedly installed on the top of the rotating rod 203, and a movable frame 206 is slidably connected to the outside of the mounting tube 110, and a movable plate 209 is fixedly installed below the two movable frames 206, and the cam 205 is slidably connected to the movable frame 206 on one side, so that the rotation of the cam 205 can drive the movable plate 209 to move, and a telescopic spring 207 is sleeved on one side of the two movable frames 206 on the outside of the mounting tube 110, and one end of the telescopic spring 207 is fixedly connected to the movable frame 206, and a fixed block 208 is fixedly installed on the other end of the telescopic spring 207, and the fixed block 208 is fixedly connected to the mounting tube 110, so that the movable frame 206 can automatically reset after moving, and a plurality of telescopic hoses 210 are connected through the bottom of the mounting tube 110, and a movable tube 211 is connected through the end of the telescopic hose 210 away from the mounting tube 110, and The bottom end of the movable pipe 211 is movably connected to the air outlet pipe 212 through a rotating joint, and several movable pipes 211 are fixedly connected to the movable plate 209, so that the drum screen 102 can be blown through the air outlet pipe 212 to prevent blockage, and a mounting frame 213 is symmetrically installed on the rear side of the mounting pipe 110, and a support plate 214 is fixedly installed on one side of the two mounting frames 213, so that the support plate 214 will not move when the movable plate 209 moves, and a plurality of teeth 216 are fixedly installed on one side of the support plate 214, and a rotating gear 215 is fixedly installed on the upper outside of the air outlet pipe 212, and the rotating gear 215 is meshed with the teeth 216, so that the air outlet pipe 212 can rotate while moving, and one end of the mounting pipe 110 passes through a fixed frame 109 on one side and is penetrated by a connecting pipe 111, which is convenient for connecting an external compressed air pump to the mounting pipe 110.

[0031] Working principle: Before using this ultrasonic dewatering screen for sewage treatment, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, an anti-blocking component 2 is arranged above and on one side of the drum screen 102. When dehydrating the sludge, the sludge is introduced into the drum screen 102 through the feed pipe 106, and then the ultrasonic generator 104 emits ultrasonic waves, and the drive motor 103 is started to drive the rotating shaft 101 to rotate, so that the drum screen 102 rotates, and the sludge is turned over, and dehydration is performed under the action of ultrasonic waves (the mechanical and cavitation effects of the ultrasonic waves themselves are used to destroy the floc structure in the sludge and remove the moisture contained therein). The air compression pump is connected through the connecting pipe 111, so that the compressed air enters the installation pipe 110, and then enters the air outlet pipe 212 through the telescopic hose 210 and the movable pipe 211, and then the compressed air is ejected through the air outlet pipe 212, and the drum screen 102 can be blown to prevent blocking.

After the cam 205 rotates one circle, it is reset under the action of the telescopic spring 207, and then with the continuous rotation of the drum screen 102, the movable plate 209 can be reciprocated, and then a plurality of movable pipes 211 can be driven to reciprocate, so that the jet range of the outlet pipe 212 can be expanded, and the drum screen 102 can be fully jetted. Through the anti-blocking component 2, when the drum screen 102 is blown to prevent blocking, the blowing range can be expanded, the inflation efficiency is improved, and the number of outlet pipes 212 does not need to be increased, thereby improving practicality;

[0032] When the movable plate 209 drives several movable tubes 211 to move back and forth, the movement of the movable plate 209 drives the air outlet pipe 212 to move. After the air outlet pipe 212 moves, the external rotating gear 215 can rotate by meshing with the teeth 216 on the support plate 214, thereby causing the air outlet pipe 212 to rotate, so that the air outlet pipe 212 can rotate back and forth during the reciprocating movement, thereby further expanding the jet range of the air outlet pipe 212 and further improving the anti-blocking efficiency.
