Description

Technical Field

[0001] This application relates to the technical field of sodium hypochlorite collection equipment, and in particular to an on-site sampling device for sodium hypochlorite transported by a tank truck. Background Technique

[0002] At present, the recognition degree of sodium hypochlorite disinfection in water treatment plants in China is continuously increasing. Many newly built or rebuilt water treatment plants in many places have begun to use sodium hypochlorite disinfection. Sodium hypochlorite disinfection is an important development direction for future drinking water disinfection. The most practical and efficient way to supply sodium hypochlorite to water treatment plants is to transport it into the plant by tank truck. Therefore, it is necessary to consider on-site sampling of the sodium hypochlorite transported by the tank truck for quality inspection.

[0003] Sodium hypochlorite is a corrosive substance. It decomposes under high heat to produce toxic corrosive fumes and decomposes when exposed to light. It is obviously not feasible to unload sodium hypochlorite from the tank truck and then sample and detect it (it is difficult to trace the origin after unloading. The supplier may not recognize the detected batch as the supply from the supplier. Even if the inspection is unqualified and the goods are returned, it needs to be reloaded, and the operation is complicated). Therefore, on-site sampling of sodium hypochlorite in the tank truck is the most feasible.

[0004] At the same time, the national standard GB19106-2013 stipulates that when sampling sodium hypochlorite in a tank truck, equal amounts of samples should be taken from three places with different depths, namely the upper, middle, and lower parts. Since sodium hypochlorite is corrosive, the method of on-site sampling by manual operation is likely to cause harm to the occupational health of operators. Therefore, there is an urgent need for a device for on-site sampling of sodium hypochlorite in a tank truck. Utility Model Content

[0005] The purpose of this application is to provide an on-site sampling device for sodium hypochlorite transported by a tank truck to solve the problem that the method of on-site sampling by manual operation is likely to cause harm to the occupational health of operators due to the corrosiveness of sodium hypochlorite.

[0006] An on-site sampling device for sodium hypochlorite transported by a tank truck provided by this application adopts the following technical solution:

[0007] An on-site sampling device for sodium hypochlorite transported by a tank truck includes a frame. A lifting mechanism is arranged on the frame. The output end of the lifting mechanism is provided with a lifting cable. One end of the lifting cable is connected with a sampler. The sampler includes a sampling bottle body connected to one end of the lifting cable through a balancing component. A bottle stopper is covered at the bottle mouth of the sampling bottle body through a sliding limiting mechanism.

[0008] Further, the sliding limit mechanism includes a plurality of limit rods arranged at the mouth of the sampling bottle body. A limit plate is slidably arranged on the plurality of limit rods. The bottle stopper is arranged on one side of the limit plate. Blocking blocks are arranged at the tops of the plurality of limit rods. An airbag assembly is further arranged on the limit plate.

[0009] Further, the airbag assembly includes an airbag arranged on the limit plate. The airbag is connected with an air delivery pipe, and the air delivery pipe is connected with an external inflation device.

[0010] Further, weight hanging rings are arranged on both sides of the limit plate.

[0011] Further, the balance assembly includes a balance plate connected to one end of the lifting cable. A plurality of lifting plates are arranged on the outer side surface of the sampling bottle body. Lifting ropes are respectively connected between the plurality of lifting plates and the balance plate.

[0012] Further, the lifting mechanism includes a lifting motor arranged between the rack and the ground. A winding wheel is arranged at the output end of the lifting motor. One end of the lifting cable is wound inside the winding wheel. A plurality of driving wheels cooperating with the lifting cable are also rotatably arranged on the rack.

[0013] Further, a distance scale is arranged on the surface of the lifting cable.

[0014] Further, a collection bucket is arranged between the lifting cable and the driving wheel at the lowest position.

[0015] Compared with the prior art, the beneficial effects of the present application are as follows: Under the combined action of the lifting mechanism and the balance assembly, the sampling bottle body on the sampler can be driven to move smoothly up and down inside the tank truck. Then, through the arrangement of the sliding limit mechanism, the bottle stopper can be displaced upward from the mouth of the sampling bottle body, so that the bottle stopper does not close with the mouth of the sampling bottle body. At this time, sodium hypochlorite at the sampling depth surges into the sampling bottle body, thereby realizing the effect of instant sampling of sodium hypochlorite.

[0016] Meanwhile, the instant sampling device of the present application can accurately sample at the upper, middle, and lower parts of the tank truck. And due to the corrosiveness of sodium hypochlorite, the structure of the sampler of the present application is simple and reliable. Moreover, the lifting mechanism is far away from sodium hypochlorite. And because of the design of the lifting mechanism, the operator can be far away from the contact with sodium hypochlorite, thereby ensuring occupational health and safety.

[0021] The following will Figure 1-2 make a further detailed description of the present application in conjunction with the appended

[0022] The embodiment of the present application discloses an instant sampling device for transporting sodium hypochlorite by a tank truck. Referring to Figure 1 , in this embodiment, the instant sampling device includes a frame 1, a lifting mechanism, a lifting cable 2 and a sampler 3. Among them, the frame 1 is installed at the position where sodium hypochlorite needs to be collected; the lifting mechanism is installed on the frame 1; one end of the lifting cable 2 is connected to the output end of the lifting mechanism, and one end of the sampler 3 is installed at the end of the lifting cable 2 away from the lifting mechanism.

[0023] At the same time, both the lifting cable 2 and the sampler 3 are made of corrosion-resistant materials. When the lifting cable 2 and the sampler 3 are placed in sodium hypochlorite for collection, they will not be corroded by sodium hypochlorite and cause damage, so as to effectively protect the lifting cable 2 and the sampler 3 and facilitate improving the service life of the lifting cable 2 and the sampler 3.

[0024] When the tank truck loaded with sodium hypochlorite is transported to one side of the frame 1, by starting the lifting mechanism on the frame 1, the lifting mechanism drives the sampler 3 to descend into the tank truck through the lifting cable 2, and the sampler 3 is used to achieve equal amount of collection of sodium hypochlorite at different depths in the tank truck.

[0025] The structures of the sampler 3 and the lifting mechanism will be described in detail below:

[0026] Specifically, referring to Figure 1 and Figure 2 , in this embodiment, the sampler 3 includes a sampling bottle body 31, a balance assembly, a bottle stopper 33 and a sliding limit mechanism. Among them, the sampling bottle body 31 is a wide-mouth bottle, and the sampling bottle body 31 is fixedly connected to the end of the lifting cable 2 away from the lifting mechanism through the balance assembly; through the setting of the balance assembly, the sampling bottle body 31 is more stable under the lifting drive of the lifting cable 2.

[0027] More specifically, the balance assembly includes a balance plate 4, a lifting plate 5, and a lifting rope 6. Among them, the top center of the balance plate 4 is fixedly connected to one end of the lifting cable 2 away from the lifting mechanism; multiple lifting plates 5 are provided, and one side of each of the multiple lifting plates 5 is respectively installed on the outer side surface of the sampling bottle body 31; multiple lifting ropes 6 are provided, and one end of each of the multiple lifting ropes 6 is respectively fixedly connected to the top of one side of these lifting plates 5, and the other end of each of the multiple lifting ropes 6 is respectively fixedly connected to the outer side walls around the balance plate 4.

[0028] When the lifting cable 2 drives the balance plate 4 to lift, the balance plate 4 lifts and pulls the lifting plate 5 through these lifting ropes 6, so as to effectively balance the lifting of the sampling bottle body 31, and further stably collect an equal amount of sodium hypochlorite.

[0029] At the same time, referring to Figure 2 , in this embodiment, the bottle stopper 33 is covered in the bottle mouth of the sampling bottle body 31, and the bottle mouth of the sampling bottle body 31 is mutually matched with the bottle stopper 33 through a sliding limit mechanism; when the bottle stopper 33 is closed on the bottle mouth of the sampling bottle body 31, by using the sliding limit mechanism, the sodium hypochlorite liquid can be used to make the bottle stopper 33 move in and out of the bottle mouth of the sampling bottle body 31 within the limited position, so as to achieve the effect of the bottle stopper 33 detaching from the bottle mouth of the sampling bottle body 31.

[0030] Specifically, in this embodiment, the sliding limit mechanism includes a limit rod 32, a limit plate 34, a blocking block 321, and an airbag 35 assembly. Among them, multiple limit rods 32 are provided, and the bottom ends of the multiple limit rods 32 are respectively fixedly installed at the bottle mouth of the sampling bottle body 31, and these limit rods 32 are perpendicular to the bottle mouth; multiple sliding holes are formed in the limit plate 34, and these sliding holes are respectively mutually matched with these limit rods 32, and the bottle stopper 33 is fixedly installed on the side of the limit plate 34 facing the sampling bottle body 31, so that the limit plate 34 drives the bottle stopper 33 to slide on these limit rods 32 through these sliding holes; and multiple blocking blocks 321 are provided, and the multiple blocking blocks 321 are respectively installed at one end of these limit rods 32 away from the sampling bottle body 31 to block the limit plate 34, so as to prevent the limit plate 34 from detaching from the outside of the limit rod 32.

[0031] At the same time, the airbag 35 assembly is arranged on the side of the limit plate 34 facing away from the bottle stopper 33; specifically, referring to Figure 1 , in this embodiment, the airbag 35 assembly includes an airbag 35 and an air delivery pipe 36. Among them, one side of the airbag 35 is fixedly installed on the side of the limit plate 34 facing away from the bottle stopper 33; the air outlet end of the air delivery pipe 36 is connected to the airbag 35, and the air inlet end of the air delivery pipe 36 is connected to an external inflation device 37.

[0032] When the sampling bottle body 31 is lowered into the tank truck to collect an equal amount of sodium hypochlorite, the airbag 35 is inflated by using an external inflating device 37 and an air pipe 36. Then, the buoyancy of the airbag 35 drives the limiting plate 34 and the bottle stopper 33 to move upward, so that the bottle stopper 33 disengages from the bottle mouth of the sampling bottle body 31, and the sodium hypochlorite at this sampling depth then surges into the sampling bottle body 31, thus completing the collection of sodium hypochlorite.

[0033] Preferably, referring to Figure 2 , in this embodiment, weight hanging rings 341 are installed on both sides of the limiting plate 34. By setting the weight hanging rings 341, the weights of the limiting plate 34 and the bottle stopper 33 can be adjusted, so that the bottle stopper 33 can close the bottle mouth of the sampling bottle body 31 when the airbag 35 is not inflated, and is not closed with the bottle mouth of the sampling bottle body 31 after the airbag 35 is inflated.

[0034] In addition, referring to Figure 1 and Figure 2 , in this embodiment, the lifting mechanism includes a lifting motor 7, a winding wheel 71 and a transmission wheel 8. Among them, the lifting motor 7 is installed between the frame 1 and the ground; the winding wheel 71 is installed at the output end of the lifting motor 7, and one end of the lifting cable 2 away from the sampler is wound in the winding wheel 71; there are two transmission wheels 8, and the two transmission wheels 8 are respectively installed at the top and bottom of the frame 1, and the two transmission wheels 8 are respectively in tight contact with the lifting cable 2 to realize guiding and limiting of the lifting cable 2.

[0035] When the lifting motor 7 is started, the output end of the lifting motor 7 drives the winding wheel 71 to rotate, and the winding wheel 71 pays out the lifting cable 2. Then, under the action of the transmission wheel 8, the lifting cable 2 submerges the sampler 3 below the liquid level of sodium hypochlorite to reach the sampling depth, so as to collect sodium hypochlorite by using the sampler 3.

[0036] Preferably, in this embodiment, distance scales are provided on the surface of the lifting cable 2. By setting the distance scales, the descending depth of the sampler 3 can be estimated by observing the distance scales, so that the sampler 3 can accurately blind-drop to the required sampling depth, and then realize the collection of sodium hypochlorite at the corresponding depth.

[0037] At the same time, a collection bucket 9 is placed between the lifting cable 2 and the transmission wheel 8 at the lowest position. The collection bucket 9 is placed on the ground to effectively collect the sodium hypochlorite flowing to the lifting motor 7 through the lifting cable 2, so that under the action of the transmission wheel 8 at the lowest position, the sodium hypochlorite flowing to the lifting motor 7 and the outside through the lifting cable 2 can be reduced.

[0038] The implementation principle of the instant sampling device for transporting sodium hypochlorite in a tank truck in the embodiment of the present application is:

[0039] When the sodium hypochlorite in the tank truck is to be sampled immediately, the airbag 35 is not inflated at this time, the bottle plug 33 on the limit plate 34 is closed to the bottle mouth of the sampling bottle body 31, and then the lifting motor 7 is started, and the output end of the lifting motor 7 drives the winding wheel 71 to rotate, and the winding wheel 71 unwinds the lifting cable 2, and then under the guiding cooperation of multiple transmission wheels 8, the lifting cable 2 lowers the sampler 3 to immerse it below the sodium hypochlorite liquid surface.

[0040] When the sampling depth is reached, the air bag 35 is inflated by the air supply pipe 36 through the inflation mechanism, so that the air bag 35 drives the limit plate 34 and the bottle plug 33 to move upward along the limit rod 32 through the buoyancy, so that the bottle plug 33 is separated from the outside of the bottle mouth of the sampling bottle body 31, that is, the bottle plug 33 is not closed with the bottle mouth, and then the sodium hypochlorite at the sampling depth flows into the sampling bottle body 31, so as to realize the instant sampling of the sodium hypochlorite at the sampling depth.

[0041] After the sampling bottle body 31 has collected sodium hypochlorite, the output end of the lifting motor 7 drives the winding wheel 71 to wind it up, and under the action of multiple transmission wheels 8 and the lifting cable 2, the sampler 3 is quickly pulled up. The bottle plug 33 on the limit plate 34 moves upward with lag due to inertia and liquid resistance, and the bottle mouth of the sampling bottle body 31 is pressed against the bottle plug 33 and quickly pulled up, thereby completing the closure of the bottle plug 33 and the bottle mouth of the sampling bottle body 31, thereby completing the sampling at the required sampling depth.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
