By setting the stirring rod on the rotating sleeve, when the rotating sleeve is rotating, the stirring rod is not only driven to follow the rotation of the rotating sleeve, but also to rotate itself, and then break up the sludge agglomeration entering the inlet of the screw pump to prevent it from clogging Progressive cavity pump.

2、通过在转动套上设置带轨道槽的旋转筒,通过齿轮配合方式,使得在转动套转动时,旋转筒自转,由于凸起和轨道槽配合,进而在旋转筒自转时带动连接杆上下往复移动,同时通过伸缩杆和第二弹簧的带动,以及移动环与推料板之间的配合,再加上定位机构的配合,使得连接杆下降时能带动移动环和推料板下降,故而在伸缩杆的作用下,推动推料板向移动环内移动直至推料板移动到进料管正下方,当连接杆向上移动时,通过移动环带动推料板向上移动,将置于进料管下方的污油泥推向进料管的进口处,从而避免吸空,而在移动环和进料口触碰时,定位机构解除限定,在第二弹簧的作用下推动伸缩杆伸出,使推料板离开进料管,进而避免阻挡物料进入,在转动套不断转动过程中,不断完成退料工作,防止吸空,保证螺杆泵正常工作。2. By setting a rotating cylinder with track grooves on the rotating sleeve, and through gear cooperation, when the rotating sleeve rotates, the rotating cylinder rotates on its own. Due to the cooperation between the protrusion and the orbital groove, the connecting rod is driven to reciprocate up and down when the rotating cylinder rotates At the same time, it is driven by the telescopic rod and the second spring, and the cooperation between the moving ring and the pushing plate, plus the cooperation of the positioning mechanism, so that when the connecting rod is lowered, the moving ring and the pushing plate can be driven down, so in Under the action of the telescopic rod, push the pusher plate to move into the moving ring until the pusher plate moves directly below the feeding pipe. When the connecting rod moves upwards, the moving ring drives the pushing plate to move upwards, and it will be placed in the feeding pipe. The sludge at the bottom is pushed to the inlet of the feed pipe, so as to avoid air suction, and when the moving ring touches the feed inlet, the positioning mechanism releases the restriction, and the telescopic rod is pushed out under the action of the second spring, so that the pusher The material plate leaves the feed pipe to avoid blocking the material from entering. During the continuous rotation of the rotating sleeve, the material return work is continuously completed to prevent air suction and ensure the normal operation of the screw pump.

3、通过在搅拌棒内设置流道,使得在搅拌棒转动时,通过流道向污油泥内通水,并利用搅拌棒的搅拌使得污油泥和水进行混合,提高污油泥的流动性,而通过大量出水孔向外出水,使得水和污油泥的混合面积加大,进而水能和污油泥进行充分混合,避免水资源的浪费。3. By setting a flow channel in the stirring rod, when the stirring rod rotates, water is passed into the sludge through the flow channel, and the stirring of the stirring rod is used to mix the sludge and water to improve the fluidity of the sludge, and The water flows out through a large number of water outlet holes, so that the mixing area of water and sludge is enlarged, and then the water energy and sludge are fully mixed to avoid waste of water resources.

4、通过齿轮配合传动方式,使得在转动套进行转动时,能够带动泵体以料槽的轴线为轴进行转动,进而带动进料管部分转动,不仅能对料斗内的污油泥进行更充分搅拌,而且还能对将料槽内各个位置的污油泥进行吸取,可将污油泥全部输送。4. Through the gear and the transmission mode, when the rotating sleeve is rotating, it can drive the pump body to rotate around the axis of the trough, and then drive the feeding pipe part to rotate, which can not only fully stir the sludge in the hopper , and can also absorb the sludge at various positions in the trough, and can transport all the sludge.

工作原理;working principle;

先将需要排出的污油泥放入料槽21内,启动电机15带动第一齿轮13和第一螺杆11转动,第一齿轮13转动带动第二齿轮14转动,进而带动第二螺杆12同步转动,故而利用第一螺杆11和第二螺杆12的配合,使得螺杆泵进行工作,将污油泥从进料管18吸入,并从出料管19排出,同时电机15转动,带动主动锥齿轮16转动,进而通过从动锥齿轮17带动第一皮带轮31转动,在皮带32的配合下带动第二皮带轮33转动,从而使得转动套41转动,由于第三齿轮42和转动套41固定连接,且第三齿轮42和内齿圈23啮合,使得泵体1绕料槽21轴线进行转动,不仅通过进料管18将污油泥进行充分搅拌,而且通过进料管18的位置移动避免污油泥因流动性不高而不能被吸走。Put the sludge that needs to be discharged into the material tank 21 first, start the motor 15 to drive the first gear 13 and the first screw 11 to rotate, the first gear 13 rotates to drive the second gear 14 to rotate, and then drives the second screw 12 to rotate synchronously, Therefore, utilize the cooperation of the first screw 11 and the second screw 12 to make the screw pump work, suck the sludge from the feed pipe 18, and discharge it from the discharge pipe 19. At the same time, the motor 15 rotates to drive the driving bevel gear 16 to rotate. And then drive the first belt pulley 31 to rotate by the driven bevel gear 17, drive the second belt pulley 33 to rotate under the cooperation of the belt 32, thereby make the rotation sleeve 41 rotate, because the 3rd gear 42 is fixedly connected with the rotation sleeve 41, and the 3rd gear 42 meshes with the inner ring gear 23, so that the pump body 1 rotates around the axis of the trough 21, not only through the feed pipe 18 to fully stir the sludge, but also through the position movement of the feed pipe 18 to avoid the sludge due to low fluidity rather than being sucked away.

同时旋转套41转动带动搅拌棒43跟随转动,使得第五齿轮441、第六齿轮442、第七齿轮443跟随转动,进而带动三个搅拌棒43跟随自转,故而带动搅拌杆431对即将进入进料管18的污油泥进行搅拌,以便将结块打碎,避免出现堵塞现象,同时通过流道432向污油泥内通入适量的水,使水和污油泥能更充分混和,提高污油泥的流动性,并且能够减少水的浪费。At the same time, the rotation of the rotating sleeve 41 drives the stirring rod 43 to follow the rotation, so that the fifth gear 441, the sixth gear 442, and the seventh gear 443 follow the rotation, and then drive the three stirring rods 43 to follow the rotation, so the driven stirring rod 431 is about to enter the feed Stir the sludge in the pipe 18 to break up the agglomerates and avoid clogging. At the same time, pass an appropriate amount of water into the sludge through the flow channel 432, so that the water and the sludge can be more fully mixed, and the flow of the sludge can be improved. performance and reduce water waste.

由于第八齿轮444和第四齿轮181啮合,使得在旋转套41转动时带动旋转筒5转动,因滑杆4613和连接环45滑动配合,连接杆4611与旋转筒5滑动配合,伸缩缸61和伸缩杆62滑动配合,伸缩缸61和旋转套41铰接,伸缩杆62和推料板462铰接,推料板462在移动环461内滑动配合,使得在旋转套41转动时,带动推料板462跟随转动,由于凸起4612与旋转筒5内的轨道槽滑动配合,故而在旋转筒5转动时,凸起4612从第二凹槽53内进入第一螺旋槽52中,带动连接杆4611上升,此时定位销712在定位槽4621内以使推料板462和移动环461定位,推料板462处于进料管18的正下方,推料板462跟随向上移动,推动伸缩杆62克服第二弹簧63收缩进伸缩缸61内,同时推料板462将进料管18下方污油泥推入进料管18的进口内,避免出现吸空现象,当凸起4612进入第一凹槽51时,控制杆711和连接环45触碰,克服第三弹簧72推动定位销71向下移动,使定位块712退出定位槽4621,进而在第二弹簧63作用下推动伸缩杆62伸出,从而推动推料板462沿移动环461的轴向向外移动,将推料板462从进料管18的正下方移走,避免影响其进料,当凸起4612从第一凹槽51内进入第二螺旋槽54时,带动连接杆4611下降,进而推动移动环461下降,由于滑块621在滑槽611内滑动,使得伸缩杆62在移动环461下降时拉动推料板462沿移动环461滑动,当凸起4612重新回到第二凹槽53时,在定位块712的斜面作用下,定位块712进入定位槽4621内形成定位,推料板462重新返回进料管18的正下方,即形成循环,使得通过旋转套41不停转动,就能通过推料板462移动以辅助污油泥进料,避免吸空。Because the eighth gear 444 is meshed with the fourth gear 181, the rotating sleeve 41 rotates to drive the rotating cylinder 5 to rotate. Because the sliding rod 4613 and the connecting ring 45 slide and fit, the connecting rod 4611 slides and fits with the rotating cylinder 5, and the telescopic cylinder 61 and The telescopic rod 62 is slidingly fitted, the telescopic cylinder 61 is hinged with the rotary sleeve 41, the telescopic rod 62 is hinged with the pusher plate 462, and the pusher plate 462 is slidably fitted in the moving ring 461, so that when the rotary sleeve 41 rotates, the pusher plate 462 is driven. Following the rotation, since the protrusion 4612 slides and fits with the track groove in the rotating cylinder 5, when the rotating cylinder 5 rotates, the protrusion 4612 enters the first spiral groove 52 from the second groove 53, driving the connecting rod 4611 to rise, At this time, the positioning pin 712 is in the positioning groove 4621 so that the pushing plate 462 and the moving ring 461 are positioned. The pushing plate 462 is directly below the feed pipe 18, and the pushing plate 462 follows and moves upwards, pushing the telescopic rod 62 to overcome the second The spring 63 shrinks into the telescopic cylinder 61, and at the same time, the pusher plate 462 pushes the dirty oil sludge under the feed pipe 18 into the inlet of the feed pipe 18 to avoid the phenomenon of air suction. When the protrusion 4612 enters the first groove 51, The control rod 711 touches the connecting ring 45, overcomes the third spring 72 and pushes the positioning pin 71 to move downward, so that the positioning block 712 withdraws from the positioning groove 4621, and then pushes the telescopic rod 62 to extend under the action of the second spring 63, thereby pushing the pushing The material plate 462 moves outwards along the axial direction of the moving ring 461, and the pushing plate 462 is removed from directly below the feed pipe 18 to avoid affecting its feeding. When the protrusion 4612 enters the second groove 51 from the first When the spiral groove 54, it drives the connecting rod 4611 to descend, and then pushes the moving ring 461 to descend. Since the slide block 621 slides in the chute 611, the telescopic rod 62 pulls the pushing plate 462 to slide along the moving ring 461 when the moving ring 461 descends. When the protrusion 4612 returns to the second groove 53, under the action of the slope of the positioning block 712, the positioning block 712 enters the positioning groove 4621 to form a positioning, and the pushing plate 462 returns directly below the feeding pipe 18, that is, forming Circulation, so that through the continuous rotation of the rotating sleeve 41, the pushing plate 462 can be moved to assist the feeding of the sludge and avoid air suction.
