采用上述技术方案,储水池内储存有雨水或者工地当中的废水,电机减速机驱动车轮沿循环轨道行进到储水池旁边时,将入水管伸入到储水池的水面下,开启进水泵,将储水池内的水抽到储水箱内,储水箱内的水较为浑浊,为了避免堵塞高压喷头,延长高压喷头的使用寿命,需要把储水箱内的水净化过滤处理,具体净化过滤过程为:开启抽水泵,抽水泵抽取储水箱内储存的浑水先经过过滤网的初步过滤后,再经进水管进入到过滤器内,清水经过过滤板后杂质被过滤掉,过滤板的孔径为0.25mm,净水进入到纯水箱内。当过滤板上附着的杂质较多后,拧下紧固螺栓,把取下压板和垫块,抠出密封条,使用钩子将过滤板从环形槽内抽出,然后更换上新的过滤板,再密封紧固。十字型的支撑架起到防止水压将过滤板压成凹形结构使过滤板脱离出环形槽。 With the above-mentioned technical scheme, rainwater or waste water in the construction site is stored in the storage tank. When the motor reducer drives the wheels to travel along the circular track to the side of the storage tank, the water inlet pipe is inserted into the water surface of the storage tank, and the water inlet pump is turned on. The water in the pool is pumped into the water storage tank, and the water in the water storage tank is relatively turbid. In order to avoid clogging the high-pressure nozzle and prolong the service life of the high-pressure nozzle, it is necessary to purify and filter the water in the water storage tank. The specific purification and filtration process is: open the pump The water pump and the water pump pump the muddy water stored in the water storage tank through the preliminary filtration of the filter, and then enter the filter through the water inlet pipe. After the clean water passes through the filter plate, the impurities are filtered out. The pore size of the filter plate is 0.25mm. into the pure water tank. When there are many impurities attached to the filter plate, unscrew the fastening bolts, take off the pressure plate and pad, pull out the sealing strip, use the hook to pull out the filter plate from the annular groove, and then replace it with a new filter plate, then Seal tight. The cross-shaped support frame prevents water pressure from pressing the filter plate into a concave structure so that the filter plate is separated from the annular groove.
水在净化过滤过程中,喷淋车在循环轨道上行进,同时开启高压水泵,抽取纯水箱内的清水,高压水经供水管进入旋转密封连接装置中的空心旋转轴,再经空心传动轴,最后进入转盘内,通过高压喷头将水雾化喷出高压水;同时驱动电机通过主动齿轮把转动动作传递给从动齿轮,从动齿轮带动空心传动轴转动,空心传动轴与空心旋转轴之间通过连接卡箍密封固定连接,在密封的同时实现转盘的旋转,转盘的旋转为高压喷头喷出的高压水进一步提高惯性,再加上高压喷头的喷射方向倾斜向上设置,这样可使使喷射的半径更大。 During the process of purifying and filtering the water, the spray car travels on the circulating track, and at the same time turns on the high-pressure water pump to extract the clean water in the pure water tank. The high-pressure water enters the hollow rotating shaft in the rotary sealing connection device through the water supply pipe, and then passes through the hollow transmission shaft , and finally into the turntable, the water is atomized and sprayed with high-pressure water through the high-pressure nozzle; at the same time, the driving motor transmits the rotation action to the driven gear through the driving gear, and the driven gear drives the hollow transmission shaft to rotate, and the connection between the hollow transmission shaft and the hollow rotating shaft The connection between them is sealed and fixed by connecting clamps, and the rotation of the turntable is realized while sealing. The rotation of the turntable further improves the inertia of the high-pressure water sprayed by the high-pressure nozzle, and the spray direction of the high-pressure nozzle is set upwards, which can make the spray The radius is larger.
本发明中的旋转密封连接装置的工作原理为:高压水经供水管进入到下接头的入水孔,再依次经过通孔、装配孔、空心旋转轴内进入到空心传动轴内;由于通孔内径小于入水孔内径,在高压水流的作用下,压盖受到高压水流向上的推力,压盖上端对填充密封圈挤压,挤压力传递到第二O型圈上,第二O型圈产生变形从而起到密封作用,第二O型圈是特殊材质所制成;使填充密封圈与空心旋转轴紧配合,高压水流经空心旋转轴流出,空心旋转轴与填充密封圈配合处采用特殊工艺处理,以便减小其与填充密封圈的摩擦力,填充密封圈采用特殊材质制作而成;空心旋转轴通过第三轴承和第四轴承安装在圆筒体内,在外力作用下空心旋转轴可以转动;而第三轴承和第四轴承在使用过程中需要润滑,通过圆筒体上设有的润滑孔添加润滑油可以润滑轴承,第一O型圈和第二密封圈用于阻挡润滑油泄露;轴承压圈上端面压紧第四轴承,轴承压圈内孔与空心旋转轴滑动配合,轴承压圈顶部的支撑套用于支撑填充密封圈,轴承压圈采用特殊材质制作而成,以减小其与空心旋转轴的摩擦力。 The working principle of the rotary sealing connection device in the present invention is: high-pressure water enters the water inlet hole of the lower joint through the water supply pipe, and then enters the hollow transmission shaft through the through hole, the assembly hole, and the hollow rotating shaft in turn; due to the inner diameter of the through hole Smaller than the inner diameter of the water inlet, under the action of high-pressure water flow, the gland is pushed upward by the high-pressure water flow, and the upper end of the gland squeezes the filling sealing ring, and the extrusion force is transmitted to the second O-ring, and the second O-ring deforms So as to play a sealing role, the second O-ring is made of special material; the filling sealing ring is closely matched with the hollow rotating shaft, and the high-pressure water flows out through the hollow rotating shaft, and the joint between the hollow rotating shaft and the filling sealing ring adopts a special process In order to reduce the friction between it and the filling sealing ring, the filling sealing ring is made of special material; the hollow rotating shaft is installed in the cylinder body through the third bearing and the fourth bearing, and the hollow rotating shaft can rotate under the action of external force ; while the third bearing and the fourth bearing need to be lubricated during use, lubricating oil can be added through the lubricating hole provided on the cylinder to lubricate the bearings, and the first O-ring and the second sealing ring are used to prevent the leakage of lubricating oil; The upper end face of the bearing pressure ring presses the fourth bearing. The inner hole of the bearing pressure ring is slidingly fitted with the hollow rotating shaft. The support sleeve on the top of the bearing pressure ring is used to support the filled sealing ring. The bearing pressure ring is made of special materials to reduce Friction with hollow rotating shaft.
当旋转密封连接装置中的可拆卸通水密封结构出现漏水时,即填充密封圈和第二O型圈损坏,高压水会沿着空心旋转轴表面进入到透水腔内,并通过透水通道、环形槽和滴水孔流出圆筒体;高压水或者沿着装配孔内壁渗入到轴承压圈上表面,再经圆筒体内壁流入到滴水孔。倘若滴水孔出水,就需要拆卸下紧固丝套,对填充密封圈和第二O型圈进行更换。第一O型圈起到防止水进入到第三轴承和第四轴承中。 When the detachable water seal structure in the rotary seal connection device leaks, that is, the filling seal ring and the second O-ring are damaged, high-pressure water will enter the water-permeable chamber along the surface of the hollow rotating shaft, and pass through the water-permeable channel, ring The groove and the drip hole flow out of the cylinder; the high-pressure water seeps into the upper surface of the bearing pressure ring along the inner wall of the assembly hole, and then flows into the drip hole through the inner wall of the cylinder. If water comes out of the drip hole, the fastening wire sleeve needs to be disassembled, and the filling sealing ring and the second O-ring are replaced. The first O-ring prevents water from entering the third and fourth bearings.
旋转密封连接装置实现固定的高压水管与高速旋转的空心传动轴之间的连接,并起到良好的密封作用,满足高压状态下的旋转与密封的要求。 The rotary sealing connection device realizes the connection between the fixed high-pressure water pipe and the high-speed rotating hollow transmission shaft, and plays a good sealing role, meeting the requirements of rotation and sealing under high pressure.
由于进水泵将储水池内沉淀的污水或者雨水抽到储水箱内,时间久了就会使储水箱底部产生较多沉淀,因此隔一段时间需要清理储水箱底部的沉淀泥浆。具体清除过程如下:将过滤网拆卸,将进水阀关闭,打开排污阀,开启清除沉淀电机,清除沉淀电机带动搅拌轴旋转,搅拌轴上端通过连接套带动搅动杆旋转,搅动杆旋转将沉淀到储水箱底部的泥浆搅动起来,然后开启抽水泵,将泥浆液从排污管抽出。同时,打开进水泵,向储水箱内再注入水,经过混合,这样使沉淀清除效果更好。 Since the water inlet pump pumps the sewage or rainwater deposited in the storage tank into the water storage tank, more sedimentation will be generated at the bottom of the water storage tank after a long time, so the sedimentation mud at the bottom of the water storage tank needs to be cleaned every once in a while. The specific cleaning process is as follows: disassemble the filter, close the water inlet valve, open the drain valve, turn on the sediment removal motor, the sediment removal motor drives the stirring shaft to rotate, the upper end of the stirring shaft drives the stirring rod to rotate through the connecting sleeve, and the stirring rod rotates to deposit The mud at the bottom of the water storage tank is stirred up, and then the pump is turned on to draw the mud liquid out of the sewage pipe. At the same time, turn on the water inlet pump, inject water into the water storage tank, and mix it, so that the sediment removal effect is better.
搅动杆设置至少两根,保证主轴的平衡稳定性。加强杆起到增强搅动杆强度的作用。可以在底板上表面设置耐磨平滑板,耐磨条与耐磨平滑板表面滑动接触;耐磨条与耐磨滑板接触旋转,尽量降低摩擦力,当耐磨条磨损后,可拧下沉头螺栓对耐磨条进行更换。 There are at least two stirring rods to ensure the balance and stability of the main shaft. The reinforcing rod plays a role in enhancing the strength of the stirring rod. A wear-resistant smooth plate can be set on the upper surface of the bottom plate, and the wear-resistant strip is in sliding contact with the surface of the wear-resistant smooth plate; the wear-resistant strip is in contact with the wear-resistant slide plate to rotate, so as to reduce friction as much as possible. When the wear-resistant strip is worn, the countersunk head can be unscrewed The bolts replace the wear strips.
由于搅拌轴垂直穿过底板,搅拌轴与底板之间具有间隙,因此在搅拌轴外壁设置动态密封结构。动态密封结构通过软密封填料(软密封填料,俗称泥状软填料,是一种新的无石棉高分子材料合成的密封填料,外观如胶泥状具有特殊的可塑性)密封转动的搅拌轴,通过拧动调节螺栓,使下环形滑块通过压缩弹簧向上顶压上环形滑块,上环形滑块向上顶压软密封填料实现搅拌轴在转动过程中的密封。另外可以将上环形滑块上表面设置为内小外大呈圆锥形的凹面结构,这样在向上挤压软密封填料时,对软密封填料的挤压力朝向搅拌轴,提高密封效果。上定位柱和下定位柱起到限定压缩弹簧的轴线保持垂直方向,使压缩弹簧起到良好的弹性状态。压力轴承起到在拧动调节螺栓时,避免下环形滑块也随着调节螺栓转动的作用。在拧动调节螺栓时,要逐个进行拧动,这样才能确保搅拌轴在圆周方向受到的软密封调料压力保持均衡,另外,可以在调节螺栓外螺纹连接与密封压盖下表面顶压配合的锁紧螺母,这样可避免调节螺母在调整到位后自动松弛。 Since the stirring shaft vertically passes through the bottom plate, there is a gap between the stirring shaft and the bottom plate, so a dynamic sealing structure is arranged on the outer wall of the stirring shaft. The dynamic sealing structure seals the rotating agitating shaft through soft sealing packing (soft sealing packing, commonly known as mud-like soft packing, which is a new asbestos-free polymer material synthetic sealing packing, which has a special plasticity in the appearance of clay). Move the adjusting bolt so that the lower annular slider presses the upper annular slider upwards through the compression spring, and the upper annular slider presses the soft sealing packing upwards to realize the sealing of the stirring shaft during rotation. In addition, the upper surface of the upper annular slider can be set as a conical concave structure with a small inside and a large outside, so that when the soft sealing packing is pressed upwards, the extrusion force on the soft sealing packing is directed towards the stirring shaft, thereby improving the sealing effect. The upper positioning post and the lower positioning post can limit the axis of the compression spring to maintain a vertical direction, so that the compression spring can play a good elastic state. The pressure bearing plays a role in preventing the lower annular slide block from rotating with the adjusting bolt when the adjusting bolt is turned. When screwing the adjusting bolts, they should be screwed one by one, so as to ensure that the soft seal seasoning pressure received by the stirring shaft in the circumferential direction remains balanced. Tighten the nut, so as to prevent the adjusting nut from loosening automatically after being adjusted in place.
综上所述,本发明结构紧凑、操作方便、密封性好、安全可靠、自动化程度高,利用废水对建筑工地的扬尘进行喷淋降尘,为工人创造了良好的工作环境,并维护了城市的环境,并能对储水箱内沉淀的泥浆进行清除,具有较高的推广应用价值。 To sum up, the present invention has the advantages of compact structure, convenient operation, good sealing performance, safety and reliability, and high degree of automation. It uses waste water to spray and reduce dust on the construction site, creating a good working environment for workers and maintaining the city's environment. environment, and can remove the mud deposited in the water storage tank, which has a high value of popularization and application.

When the motor reducer 34 drives the wheels 35 to advance to the side of the water storage tank 31 along the circulation track 30, the water inlet pipe 41 is extended into the water storage tank 31. Under the water surface, turn on the water inlet pump 40 to pump the water in the water storage tank 31 into the water storage tank 36. The water in the water storage tank 36 is relatively turbid. The water purification and filtration treatment in 36, the specific purification and filtration process is: open the water pump 38, the water pump 38 extracts the muddy water stored in the water storage tank 36, first passes through the filter screen 43 for preliminary filtration, and then enters the filter 37 through the water inlet pipe 42 Inside, impurities are filtered out after clear water passes through the filter plate 52, the aperture of the filter plate 52 is 0.25mm, and the clean water enters in the pure water tank 39.

The cross-shaped support frame 55 prevents water pressure from pressing the filter plate 52 into a concave structure so that the filter plate 52 is separated from the annular groove 79 .
水在净化过滤过程中,喷淋车102在循环轨道30上行进,同时开启高压水泵48,抽取纯水箱39内的清水,高压水经供水管47进入旋转密封连接装置65中的空心旋转轴72,再经空心传动轴68,最后进入转盘99内,通过高压喷头101将水雾化喷出高压水;同时驱动电机64通过主动齿轮70把转动动作传递给从动齿轮69,从动齿轮69带动空心传动轴68转动,空心传动轴68与空心旋转轴72之间通过连接卡箍84密封固定连接,在密封的同时实现转盘99的旋转,转盘99的旋转为高压喷头101喷出的高压水进一步提高惯性,再加上高压喷头101的喷射方向倾斜向上设置,这样可使使喷射的半径更大。 During the water purification and filtration process, the spray truck 102 travels on the circulating track 30, and at the same time, the high-pressure water pump 48 is turned on to extract the clean water in the pure water tank 39, and the high-pressure water enters the hollow rotating shaft in the rotary sealing connection device 65 through the water supply pipe 47 72, then through the hollow drive shaft 68, finally enters the turntable 99, and sprays the high-pressure water through the high-pressure nozzle 101; at the same time, the driving motor 64 transmits the rotation action to the driven gear 69 through the driving gear 70, and the driven gear 69 Drive the hollow transmission shaft 68 to rotate, the hollow transmission shaft 68 and the hollow rotating shaft 72 are sealed and fixedly connected by the connecting clamp 84, and the rotation of the turntable 99 is realized while sealing, and the rotation of the turntable 99 is the high-pressure water sprayed by the high-pressure nozzle 101. The inertia is further improved, and the injection direction of the high-pressure spray head 101 is arranged obliquely upward, so that the radius of injection can be made larger.
本发明中的旋转密封连接装置65的工作原理为:高压水经供水管47进入到下接头85的入水孔90,再依次经过通孔96、装配孔91、空心旋转轴72内进入到空心传动轴68内;由于通孔96内径小于入水孔90内径,在高压水流的作用下,压盖95受到高压水流向上的推力,压盖95上端对填充密封圈93挤压,挤压力传递到第二O型圈94上,第二O型圈94产生变形从而起到密封作用,第二O型圈94是特殊材质所制成;使填充密封圈93与空心旋转轴72紧配合,高压水流经空心旋转轴72流出,空心旋转轴72与填充密封圈93配合处采用特殊工艺处理,以便减小其与填充密封圈93的摩擦力,填充密封圈93采用特殊材质制作而成;空心旋转轴72通过第三轴承73和第四轴承74安装在圆筒体71内,在外力作用下空心旋转轴72可以转动;而第三轴承73和第四轴承74在使用过程中需要润滑,通过圆筒体71上设有的润滑孔98添加润滑油可以润滑轴承,第一O型圈81和第二密封圈83用于阻挡润滑油泄露;轴承压圈76上端面压紧第四轴承74,轴承压圈76内孔与空心旋转轴72滑动配合,轴承压圈76顶部的支撑套用于支撑填充密封圈93,轴承压圈76采用特殊材质制作而成,以减小其与空心旋转轴72的摩擦力。 The working principle of the rotary sealing connection device 65 in the present invention is: high-pressure water enters the water inlet hole 90 of the lower joint 85 through the water supply pipe 47, and then enters the hollow transmission through the through hole 96, the assembly hole 91, and the hollow rotating shaft 72 in sequence. Inside the shaft 68; because the inner diameter of the through hole 96 is smaller than the inner diameter of the water inlet hole 90, under the action of high-pressure water flow, the gland 95 is pushed upward by the high-pressure water flow, and the upper end of the gland 95 squeezes the filling sealing ring 93, and the extrusion force is transmitted to the first On the second O-ring 94, the second O-ring 94 is deformed to play a sealing role. The second O-ring 94 is made of special material; the filling sealing ring 93 is tightly matched with the hollow rotating shaft 72, and the high-pressure water flows through The hollow rotating shaft 72 flows out, and the joint between the hollow rotating shaft 72 and the filling sealing ring 93 is treated with a special process in order to reduce the friction between it and the filling sealing ring 93. The filling sealing ring 93 is made of special materials; the hollow rotating shaft 72 The third bearing 73 and the fourth bearing 74 are installed in the cylindrical body 71, and the hollow rotating shaft 72 can rotate under the action of an external force; while the third bearing 73 and the fourth bearing 74 need to be lubricated during use, through the cylindrical body The lubricating hole 98 that is provided with on 71 can lubricate the bearing by adding lubricating oil, the first O-ring 81 and the second seal ring 83 are used to stop the lubricating oil from leaking; 76 inner holes are slidably matched with the hollow rotating shaft 72, and the support sleeve at the top of the bearing pressure ring 76 is used to support the filled sealing ring 93. The bearing pressure ring 76 is made of special materials to reduce the friction between it and the hollow rotating shaft 72.
当旋转密封连接装置65中的可拆卸通水密封结构出现漏水时,即填充密封圈93和第二O型圈94损坏,高压水会沿着空心旋转轴72表面进入到透水腔78内,并通过透水通道80、环形槽79和滴水孔97流出圆筒体71;高压水或者沿着装配孔91内壁渗入到轴承压圈76上表面,再经圆筒体71内壁流入到滴水孔97。倘若滴水孔97出水,就需要拆卸下紧固丝套86,对填充密封圈93和第二O型圈94进行更换。第一O型圈81起到防止水进入到第三轴承73和第四轴承74中。 When the detachable water sealing structure in the rotary sealing connection device 65 leaks, that is, the filling sealing ring 93 and the second O-ring 94 are damaged, high-pressure water will enter the water-permeable chamber 78 along the surface of the hollow rotating shaft 72, and The cylinder 71 flows out through the permeable channel 80, the annular groove 79 and the drip hole 97; the high-pressure water penetrates into the upper surface of the bearing pressure ring 76 or along the inner wall of the assembly hole 91, and then flows into the drip hole 97 through the inner wall of the cylinder 71. If water comes out from the drip hole 97, the fastening wire sleeve 86 needs to be disassembled, and the filling sealing ring 93 and the second O-ring 94 are replaced. The first O-ring 81 prevents water from entering the third bearing 73 and the fourth bearing 74 .
由于进水泵38将储水池31内沉淀的污水或者雨水抽到储水箱36内,时间久了就会使储水箱36底部产生较多沉淀,因此隔一段时间需要清理储水箱36底部的沉淀泥浆。具体清除过程如下:将过滤网43拆卸,将进水阀44关闭,打开排污阀29,开启清除沉淀电机7,清除沉淀电机7带动搅拌轴8旋转,搅拌轴8上端通过连接套10带动搅动杆11旋转,搅动杆11旋转将沉淀到储水箱36底部的泥浆搅动起来,然后开启抽水泵38,将泥浆液从排污管28抽出。同时,打开进水泵40,向储水箱36内再注入水,经过混合,这样使沉淀清除效果更好。 Since the sewage or rainwater deposited in the water storage tank 31 is pumped into the water storage tank 36 by the water inlet pump 38, more precipitation will be produced at the bottom of the water storage tank 36 after a long time, so the sedimentation mud at the bottom of the water storage tank 36 needs to be cleaned at intervals. The specific removal process is as follows: disassemble the filter screen 43, close the water inlet valve 44, open the sewage valve 29, open the sediment removal motor 7, the sediment removal motor 7 drives the stirring shaft 8 to rotate, and the upper end of the stirring shaft 8 drives the stirring rod through the connecting sleeve 10 11 rotates, and the stirring rod 11 rotates and stirs up the mud deposited at the bottom of the water storage tank 36, and then the water pump 38 is opened to extract the mud liquid from the blowdown pipe 28. Simultaneously, open the water inlet pump 40, inject water again in the water storage tank 36, through mixing, make the deposit removal effect better like this.
拨动杆11设置至少两根,保证主轴的平衡稳定性。加强杆12起到增强拨动杆11强度的作用。耐磨条13与耐磨滑板接触旋转,尽量降低摩擦力,当耐磨条13磨损后,可拧下沉头螺栓对耐磨条13进行更换。 Toggle lever 11 is provided with at least two, guarantees the balance stability of main shaft. The reinforcing rod 12 plays a role in enhancing the strength of the toggle rod 11 . The wear-resistant strip 13 contacts and rotates with the wear-resistant slide plate to reduce friction as much as possible. When the wear-resistant strip 13 wears out, the countersunk bolt can be unscrewed to replace the wear-resistant strip 13.
由于搅拌轴8垂直穿过底板2,搅拌轴8与底板2之间具有间隙,因此在搅拌轴8外壁设置动态密封结构。动态密封结构通过软密封填料21(软密封填料21,俗称泥状软填料,是一种新的无石棉高分子材料合成的密封填料,外观如胶泥状具有特殊的可塑性)密封转动的搅拌轴8,通过拧动调节螺栓25,使下环形滑块19通过压缩弹簧24向上顶压上环形滑块20,上环形滑块20向上顶压软密封填料21实现搅拌轴8在转动过程中的密封,另外由于上环形滑块20上表面为内小外大呈圆锥形的凹面结构,这样在向上挤压软密封填料21时,对软密封填料21的挤压力朝向搅拌轴8,提高密封效果。上定位柱22和下定位柱23起到限定压缩弹簧24的轴线保持垂直方向,使压缩弹簧24起到良好的弹性状态。压力轴承26起到在拧动调节螺栓25时,避免下环形滑块19也随着调节螺栓25转动的作用。在拧动调节螺栓25时,要逐个进行拧动,这样才能确保搅拌轴8在圆周方向受到的软密封调料压力保持均衡,另外,可以在调节螺栓25外螺纹连接与密封压盖16下表面顶压配合的锁紧螺母,这样可避免调节螺母在调整到位后自动松弛。 Since the stirring shaft 8 passes through the bottom plate 2 vertically, there is a gap between the stirring shaft 8 and the bottom plate 2 , so a dynamic sealing structure is provided on the outer wall of the stirring shaft 8 . The dynamic sealing structure seals the rotating stirring shaft 8 through soft sealing packing 21 (soft sealing packing 21, commonly known as mud-like soft packing, is a new sealing packing made of asbestos-free polymer material, which has a special plasticity in appearance like clay) , by turning the adjusting bolt 25, the lower annular slider 19 presses the upper annular slider 20 upwards through the compression spring 24, and the upper annular slider 20 presses the soft sealing packing 21 upwards to realize the sealing of the stirring shaft 8 during rotation, In addition, since the upper surface of the upper annular slider 20 is a conical concave structure with a small inside and a large outside, when the soft sealing packing 21 is pressed upward, the extrusion force on the soft sealing packing 21 is directed towards the stirring shaft 8, thereby improving the sealing effect. The upper positioning post 22 and the lower positioning post 23 can limit the axis of the compression spring 24 to maintain a vertical direction, so that the compression spring 24 can play a good elastic state. The pressure bearing 26 plays a role in preventing the lower annular slider 19 from rotating with the adjusting bolt 25 when the adjusting bolt 25 is turned. When turning the adjusting bolt 25, it is necessary to turn it one by one, so as to ensure that the soft seal seasoning pressure received by the stirring shaft 8 in the circumferential direction remains balanced. Press-fit lock nut, which prevents the adjusting nut from loosening automatically after being adjusted in place.
