Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a steam driving device for a multi-effect evaporator. Background Technique

[0002] The MVR evaporator is a new type of highly efficient and energy-saving evaporation device mainly applied to the pharmaceutical industry. This device uses low-temperature and low-pressure steam technology and clean energy as the energy to generate steam, separating the water in the medium. It is an internationally advanced evaporation technology and an upgraded product to replace traditional evaporators.

[0003] In the Chinese utility model patent, such as the utility model of CN220213941U, it particularly discloses an MVR multi-effect evaporator, which can enable the water to be distilled to enter the cylinder inside the evaporator shell. And, under the action of the driving device, the cylinder can rotate, so as to throw the water inside the cylinder onto the inner wall of the shell. Since the temperature of the inner wall of the shell is relatively high, the water on the inner wall of the shell will quickly evaporate to form water vapor, thus greatly improving the distillation efficiency of the water inside the shell.

[0004] Due to the fixed position of the cylinder in the above technology, the positions where the cylinder throws water are all at the same position of the shell. As a result, the temperature of this position of the cylinder drops relatively fast. When the subsequent water contacts the cylinder wall at this position again, the temperature cannot reach the evaporation temperature of the water, so it cannot quickly evaporate to form water vapor. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the background technique, and a steam driving device for a multi-effect evaporator is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A steam driving device for a multi-effect evaporator includes a shell. A first input pipe and a second input pipe are respectively communicated with the outside of the shell. A guiding shell is fixedly installed at one end of the second input pipe located inside the shell. A water baffle is fixedly installed inside the guiding shell. A fixed seat is fixedly installed on the outside of the shell. A water storage chamber is rotatably connected inside the shell. A plurality of sieve holes are formed in the water storage chamber. A motor is fixedly installed on the top surface of the fixed seat. The motor drives the water storage chamber to rotate through a telescopic mechanism. A lead screw sleeve is rotatably connected to the outside of the water storage chamber. A reciprocating lead screw is rotatably connected inside the shell, and the reciprocating lead screw is in threaded connection with the lead screw sleeve.

[0008] Preferably, the telescopic mechanism includes a telescopic base, and the telescopic base is connected to the output shaft of the motor. A square chute is provided in the telescopic base. A telescopic rod is slidably connected in the square chute. The shape of the telescopic rod is square, and one end of the telescopic rod is fixedly connected to the bottom of the water storage chamber.

[0009] Preferably, a driving gear is installed on the telescopic base. One end of the reciprocating lead screw penetrates through the housing and is rotatably connected to the top surface of the fixed seat. A transmission gear is installed at one end of the reciprocating lead screw, and the transmission gear meshes with the driving gear.

[0010] Preferably, a baffle is fixedly installed at the top end of the reciprocating lead screw, and the diameter length of the baffle is greater than the diameter length of the reciprocating lead screw.

[0011] Preferably, an upper arc plate and a lower arc plate are respectively fixedly installed on the outside of the water storage chamber, and the lead screw sleeve is rotatably connected between the upper arc plate and the lower arc plate.

[0012] Preferably, the water storage chamber is located directly below the guiding shell, and the diameter length of the water baffle is smaller than the diameter length of the top opening of the guiding shell.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting devices such as a reciprocating lead screw, a telescopic mechanism, a lead screw sleeve, an upper arc plate, and a lower arc plate, the present utility model realizes that the rotation of the reciprocating lead screw drives the lead screw sleeve to reciprocate. Through the limitation of the lead screw sleeve by the upper arc plate and the lower arc plate, the purpose of driving the water storage chamber to rotate and slide up and down at the same time is achieved. Furthermore, the water thrown out by the water storage chamber is evenly distributed on the inner walls of different heights of the housing, so that the water quickly evaporates to form water vapor.

[0015] 2. By setting devices such as a guiding shell and a water baffle, the present utility model realizes blocking the water column in the second input pipe through the water baffle, so that the water column splashes and slides down along the inner wall of the guiding shell, thus turning into a water curtain and falling downward. This can increase the contact area between water and heat, so that more water can evaporate simultaneously, thereby achieving the purpose of improving the evaporation efficiency.

[0016] In summary, when the present utility model is in use, the operation is simple. It can drive the water storage chamber to rotate and slide up and down at the same time, so that the water thrown out by the water storage chamber is evenly distributed on the inner walls of different heights of the housing, so that the water quickly evaporates to form water vapor. At the same time, the input water column can be turned into a water curtain, thereby increasing the contact area between water and heat and improving the evaporation efficiency.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Refer to Figures 1-3 , a steam driving device for a multi-effect evaporator, including a housing 1. The outside of the housing 1 is respectively communicated with a first input pipe 2 and a second input pipe 3. One end of the second input pipe 3 located inside the housing 1 is fixedly installed with a guiding shell 12. A water baffle 13 is fixedly installed inside the guiding shell 12. The position of the water storage chamber 14 is directly below the guiding shell 12. The diameter length of the water baffle 13 is smaller than the diameter length of the top opening of the guiding shell 12. It is worth noting that the first input pipe 2 inputs industrial water steam, and at the same time, the second input pipe 3 distributes water inside the housing 1. At the same time, the water input by the second input pipe 3 is blocked by the water baffle 13, so that the water source is dispersed, and then flows downward along the inner wall of the guiding shell 12, thus forming a water curtain, increasing the contact area between water molecules and heat, so that more water can be evaporated simultaneously, thereby improving the evaporation efficiency;

[0024] A fixed seat 4 is fixedly installed on the outside of the housing 1. A water storage chamber 14 is rotatably connected inside the housing 1. A plurality of sieve holes are opened on the water storage chamber 14. A motor 5 is fixedly installed on the top surface of the fixed seat 4. The water storage chamber 14 throws water onto the inner wall of the housing 1, so as to evaporate quickly;

[0025] The motor 5 drives the water storage chamber 14 to rotate through a telescopic mechanism. The telescopic mechanism includes a telescopic base 9, and the telescopic base 9 is connected to the output shaft of the motor 5. A square chute is provided in the telescopic base 9, and an extension rod 10 is slidably connected in the square chute. The shape of the extension rod 10 is square, and one end of the extension rod 10 is fixedly connected to the bottom of the water storage chamber 14. It should be noted that due to the arrangement of the extension rod 10 and the square chute, when the motor 5 drives the telescopic base 9 to rotate, the extension rod 10 will be driven to rotate synchronously;

[0026] A lead screw sleeve 15 is rotatably connected to the outside of the water storage chamber 14, and a reciprocating lead screw 6 is rotatably connected in the housing 1. The reciprocating lead screw 6 is threadedly connected to the lead screw sleeve 15. An upper arc plate 16 and a lower arc plate 17 are fixedly installed on the outside of the water storage chamber 14, and the lead screw sleeve 15 is rotatably connected between the upper arc plate 16 and the lower arc plate 17. It should be noted that through the threaded connection between the lead screw sleeve 15 and the reciprocating lead screw 6, and at the same time being rotatably connected to the water storage chamber 14, the lead screw sleeve 15 itself cannot rotate. When the reciprocating lead screw 6 rotates, the lead screw sleeve 15 performs reciprocating sliding, and the lead screw sleeve 15 is limited by the upper arc plate 16 and the lower arc plate 17. Therefore, when the lead screw sleeve 15 slides, it drives the water storage chamber 14 to slide up and down without affecting the rotation of the water storage chamber 14;

[0027] A driving gear 8 is installed on the telescopic base 9. One end of the reciprocating lead screw 6 passes through the housing 1 and is rotatably connected to the top surface of the fixed seat 4. A transmission gear 7 is installed at one end of the reciprocating lead screw 6, and the transmission gear 7 is meshed with the driving gear 8. A baffle 11 is fixedly installed at the top end of the reciprocating lead screw 6, and the diameter length of the baffle 11 is greater than the diameter length of the reciprocating lead screw 6. The baffle 11 prevents the lead screw sleeve 15 from pushing the reciprocating lead screw 6. At the same time, the driving gear 8 drives the transmission gear 7 to rotate, which can reduce the number of motors 5 used in the device, thereby reducing the manufacturing cost of the device.

[0028] When the utility model is in use, first, industrial water vapor is input into the housing 1 through the first input pipe 2, so that the inside of the housing 1 is heated. Then, water is distributed into the housing 1 through the second input pipe 3. The water source is blocked by the water baffle 13 and then flows along the inner wall of the guiding shell 12, so that the water column is transformed into a water curtain and falls downward, and finally falls into the water storage chamber 14. During the falling process, the water molecules in the water curtain can increase the contact area with heat compared with the water column, so that more water can evaporate simultaneously, thereby improving the evaporation efficiency;

[0029] Finally, the water falls into the water storage chamber 14. The motor 5 is started to drive the telescopic base 9 to rotate. Since the extension rod 10 is square, the extension rod 10 is driven to rotate, thereby driving the water storage chamber 14 to rotate. At the same time, when the telescopic base 9 rotates, the reciprocating lead screw 6 is driven to rotate through the arrangement of the driving gear 8 and the transmission gear 7. Since the lead screw sleeve 15 rotatably connected to the outside of the water storage chamber 14 is threadedly connected to the reciprocating lead screw 6, the lead screw sleeve 15 is driven to slide reciprocally. The lead screw sleeve 15 is limited by the upper arc-shaped plate 16 and the lower arc-shaped plate 17, thereby driving the water storage chamber 14 to slide up and down, enabling the extension rod 10 to slide within the telescopic base 9. Thus, the water thrown out by the water storage chamber 14 is evenly distributed on the inner walls of different heights of the housing 1, so that the water quickly evaporates to form water vapor.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
