The farmland is irrigated by using water with salt content and chloride ions which seriously exceed the standard for a long time, so that the secondary salinization of soil is more and more serious, the yield of crops is reduced, and the benefit is reduced year by year. The conductivity of the yellow river for detecting the water quality salt content index in the Qinghai origin is only 200 mu S/cm, when reaching the toe cap of the middle stream of the yellow river, the conductivity is increased to 800-1000 mu S/cm, and when reaching the Jinan and Dongying of the lower stream of the yellow river, the conductivity is as high as 1000-1500 mu S/cm. The increase of the hardness of the high-salinity underground water has certain harm to human health, and can also corrode industrial equipment and shorten the service life of the equipment. When the hardness of water is required to be reduced in industry, the water is softened with high cost, calcium chloride and magnesium softening waste liquid is discharged and then permeates into the ground to further pollute the ground water, so that the chloride and the hardness of the ground water are increased, and a vicious circle is formed.

In consideration of the requirement of environmental protection, the traditional mine drainage in the coal industry cannot continuously adopt a direct drainage mode because the salt content exceeds the standard, and the salt in water needs to be removed so as to be discharged. The treatment process commonly used by enterprises at present is membrane method + evaporation, and has the defects of large energy consumption, large maintenance amount, unstable operation and the like, and in addition, the equipment is easy to generate the problems of scaling, blockage, corrosion and the like.

Similarly, when the material coming out from the lower outlet of the lower cavity 38 needs to be discharged into the ice-melting recovery tank 21, the material distribution plate 43 is inclined towards the ice-melting recovery tank 21 only by rotating the motor 51 in the reverse direction, so that the material coming out from the lower cavity 38 falls onto the material distribution plate 43 and slides into the ice-melting recovery tank 21 along the material distribution plate 43. After the material in the lower cavity 38 is discharged, the material distributing plate 43 is driven by the motor 51 to return to the horizontal state.

When the material distributing plate 43 is in an inclined state to discharge the materials from the lower cavity 38 into the brine tank 29 or the ice-melting recovery tank 21, the downward inclined end of the material distributing plate 43 bears most of the weight of the materials, so that the whole material distributing plate 43 is unevenly stressed, and the material distributor 19 is easily damaged. In order to avoid that the dispenser 19 is damaged during use and also to make the operation of the dispenser 19 more smooth, a telescopic device is arranged in the dispenser 19. When the material distributing plate 43 is driven by the motor 51 to incline, the expansion device at one end of the material distributing plate 43 rotating downwards contracts, and the expansion device at one end of the material distributing plate 43 rotating upwards expands, so that the expansion device can support the material distributing plate 43 in an inclined state, the material distributing plate is not easy to damage due to uneven stress when in use, and the operation is more stable.

In the first embodiment of the distributor 19, the telescopic device is an air cylinder 49 or a hydraulic cylinder 49, the cylinder of the air cylinder 49 or the hydraulic cylinder 49 is hinged on the base 45, and the piston rod of the air cylinder 49 or the hydraulic cylinder 49 is hinged on the material distributing plate 43. The concrete mode that the cylinder barrel of the air cylinder 49 or the hydraulic cylinder 49 is hinged on the base 45 is as follows: the cylinder 49 or the cylinder barrel of the hydraulic cylinder 49 is hinged between two oppositely arranged first lugs 50, and the two first lugs 50 are fixedly arranged on the base 45. The concrete mode that the piston rod of the air cylinder 49 or the hydraulic cylinder 49 is hinged on the material distributing plate 43 is as follows: the piston rod of the cylinder 49 or the hydraulic cylinder 49 is hinged between two oppositely arranged second lugs 48, and the two second lugs 48 are fixedly arranged on the material distributing plate 43. The air cylinder 49 or the hydraulic cylinder 49 can also be used as a backup power source for the rotation of the material distributing plate 43 in addition to the above-mentioned function of supporting the material distributing plate 43, that is, when the motor 51 fails, the material distributing plate 43 is rotated by controlling the air cylinder 49 or the hydraulic cylinder 49, that is, when the air cylinder 49 or the hydraulic cylinder 49 at one end of the material distributing plate 43 contracts and the air cylinder 49 or the hydraulic cylinder 49 at the other end of the material distributing plate 43 expands, the material distributing plate 43 rotates to be in an inclined state, and conversely, when the air cylinder 49 or the hydraulic cylinder 49 at one end of the material distributing plate 43 changes from contracting to expanding and the air cylinder 49 or the hydraulic cylinder 49 at the other end of the material distributing plate 43 changes from expanding to contracting, the material distributing plate 43 returns to a horizontal state. Retraction of the cylinder 49 or cylinder 49 means retraction of the piston rod into the cylinder and extension of the cylinder 49 or cylinder 49 means extension of the piston rod out of the cylinder. Two air cylinders 49 or hydraulic cylinders 49 are respectively arranged at two ends of the material separating plate 43.

As shown in fig. 11, the specific manner of the transmission shaft 47 rotatably mounted on the base 45 is as follows: two vertical plates 44 which are oppositely arranged are fixedly arranged on the base 45, and the transmission shaft 47 is rotatably arranged on the two vertical plates 44 through a bearing.

As shown in fig. 10 and 13, the supporting frame 46 is V-shaped, the middle of the supporting frame 46 is fixedly connected to the transmission shaft 47, and both ends of the supporting frame 46 are fixedly connected to the material distributing plate 43. The support frame 46 is designed to be V-shaped, so that the support frame can support the material distributing plate 43 more stably.

As shown in fig. 10 to 13, a material containing groove 52 is provided between the two ends of the top surface of the material distributing plate 43, that is, the material containing groove 52 extends between the two ends of the material distributing plate 43, and after the material falls on the top surface of the material distributing plate 43, when the material distributing plate 43 is inclined, the material can only slide off from the two ends of the material distributing plate 43. The depth of the material containing groove 52 is gradually reduced from the middle to the two ends, that is, the material containing groove 52 is designed into an arc-shaped groove structure. When the material from the lower cavity 38 falls on the top surface of the material distributing plate 43, the material slides down the material containing groove 52 into the brine tank 29 or the ice melting recovery tank 21. As shown in fig. 13, when the material slides down from the left end of the material containing groove 52, due to the design of the arc-shaped groove, the height of the right end of the material containing groove 52 is higher, so that the material falling on the material distributing plate 43 is not easy to slide down from the right end, but only can slide down from the left end of the material distributing plate 43, that is, the material containing groove 52 is designed into the arc-shaped groove to protect the material.

Fig. 14 shows a second embodiment of the distributor 19, which differs from the first embodiment in the structure of the telescopic device, namely: the telescopic device in the embodiment comprises an outer sleeve barrel 56 and an inner rod 53, wherein one end of the bottom of the outer sleeve barrel 56 is hinged to the base 45, the lower end of the inner rod 53 is hermetically sleeved at one end of the opening of the outer sleeve barrel 56, the upper end of the inner rod 53 is hinged to the material distributing plate 43, a first spring 58 is arranged in a barrel cavity of the outer sleeve barrel 56, and the first spring 58 is connected between the lower end of the inner rod 53 and the bottom of the inner barrel of the outer sleeve barrel 56.

In order to enhance the sealing performance between the inner rod 53 and the outer sleeve barrel 56, a sealing ring 54 is arranged between the opening of the outer sleeve barrel 56 and the inner rod 53, and the sealing ring 54 is fixedly arranged on the opening of the outer sleeve barrel 56. In order to prevent the inner rod 53 from slipping off the outer sleeve barrel 56, an annular baffle 55 is arranged at the barrel opening of the outer sleeve barrel 56, the inner rod 53 is inserted into the annular baffle 55, the sealing ring 54 is fixedly arranged on the annular baffle 55, and a radial flange 57 is arranged at the lower end of the inner rod 53, so that when the inner rod 53 extends out of the outer sleeve barrel 56, the radial flange 57 at the lower end of the inner rod 53 can abut against the annular baffle 55 along with the continuation of the extending action, and therefore, under the blocking of the annular baffle 55, the lower end of the inner rod 53 cannot be separated from the outer sleeve barrel 56, and the inner rod 53 and the outer sleeve barrel 56 are prevented from slipping off each other in the movement process.

Under the drive of the motor 51, when the material distributing plate 43 inclines, the expansion device at the downward-inclined end of the material distributing plate 43 contracts (at the moment, the inner rod 53 moves downwards to compress the first spring 58), the expansion device at the upward-inclined end of the material distributing plate 43 expands (at the moment, the inner rod 53 moves upwards to stretch the first spring 58), otherwise, when the motor 51 rotates reversely, the expansion device at the downward-inclined end of the material distributing plate 43 changes from contracting to expanding (at the moment, the inner rod 53 moves upwards, the first spring 58 changes from a compressed state to a natural state), the expansion device at the upward-inclined end of the material distributing plate 43 changes from expanding to contracting (at the moment, the inner rod 53 moves downwards, the first spring 58 changes from a stretched state to a natural state), and the material distributing plate 43 returns to a horizontal state.

As shown in fig. 15 and with reference to fig. 16 to 19, the cleaning nozzle 35 includes a nozzle body 60 in a barrel shape, an inner diameter of the nozzle body 60 gradually decreases from a bottom of the barrel to a top of the barrel, a support plate 63 is fixedly disposed at the top of the nozzle body 60, an overflowing hole 62 is disposed at an edge of the support plate 63, a blocking plate 67 is disposed in a barrel cavity of the nozzle body 60, the blocking plate 67 is located below the support plate 63, a second spring 66 is connected between the blocking plate 67 and the support plate 63, a nozzle hole 64 is disposed at the bottom of the nozzle body 60, and the top of the nozzle body 60 is fixedly connected to one end of the cleaning pipeline 32, that is, the end of the cleaning pipeline 32 located in the ice filter 37.

As shown in fig. 18 and 19, when the cleaning nozzle 35 is not used, the second spring 66 has a pre-tightening tension, and under the tension of the second spring 66, the blocking plate 67 is tightly attached to the inner wall of the barrel cavity of the nozzle body 60, so that the barrel cavity is divided into an upper space and a lower space which are sealed and isolated from each other. When the cleaning nozzle 35 is used, water enters the barrel cavity of the nozzle body 60 from the overflowing hole 62 of the supporting plate 63, then under the action of water pressure, the water pushes the blocking plate 67 to move downwards (at the moment, the second spring 66 stretches), because the inner diameter of the barrel cavity is gradually increased from top to bottom, when the blocking plate 67 moves downwards, an annular gap is formed between the blocking plate 67 and the barrel cavity, the annular gap is communicated with the upper space and the lower space of the barrel cavity, and then the water enters the lower space from the upper space of the barrel cavity through the annular gap and is sprayed out from the spraying hole 64 at the bottom of the barrel. After the water spraying is finished, the water source is closed, the water pressure disappears, and the blocking plate 67 moves upwards under the action of the pulling force of the second spring 66 until the blocking plate is tightly attached to the inner wall of the barrel cavity again (at the moment, the second spring 66 is restored). Thus, foreign materials such as dust can be prevented from entering the pipe through the cleaning nozzle 35 to cause clogging.

As shown in fig. 18 and 19, the upper end of the second spring 66 is fixedly connected to the middle of the bottom surface of the supporting plate 63, the lower end of the second spring 66 is fixedly connected to the middle of the top surface of the blocking plate 67, a sleeve 65 is arranged on the periphery of the second spring 66, the upper end of the sleeve 65 is fixedly connected to the middle of the bottom surface of the supporting plate 63, the lower end of the sleeve 65 is fixedly connected to the middle of the top surface of the blocking plate 67, and the sleeve 65 is made of elastic waterproof material. Because the upper end of the sleeve 65 is fixedly connected to the middle of the bottom surface of the support plate 63, and the overflowing hole 62 is arranged at the edge of the support plate 63, the water flow entering the barrel cavity from the overflowing hole 62 only flows outside the sleeve 65, so that under the protection of the sleeve 65, the second spring 66 cannot be in contact with the water flow, the second spring 66 can be prevented from being corroded by the water flow, and the service life of the second spring 66 is prolonged.

As shown in fig. 18 and 19, a sealing ring 68 is provided at an edge of the blocking plate 67, which can further enhance the sealing performance between the blocking plate 67 and the inner wall of the barrel cavity of the nozzle body 60.

As shown in fig. 18 and 19, a threaded cylinder 61 is fixedly connected to the spout of the nozzle body 60, and the threaded cylinder 61 is screwed to one end of the cleaning pipeline 32, that is, the end of the cleaning pipeline 32 located in the ice filter cylinder 37. Of course, the nozzle body 60 may be connected to the end of the cleaning pipe 32 by other connection methods, such as welding, interference fit, etc.
