Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production, in particular to a cleaning device. Background Art

[0002] The rehumidifier is an important mechanism for loosening and rehumidifying tobacco blocks, which can moisten and heat up the tobacco blocks to achieve the effect of softening and loosening. The heater is an important component of the rehumidifier, which is used to increase the temperature of the rehumidification cylinder. However, in the actual production process, tobacco block fragments, dust and other substances are easily adsorbed on the surface of the heater. Over time, these adhesions accumulate thicker and thicker on the surface of the heater, which directly affects the heat transfer efficiency of the heater, making the temperature of the tobacco leaves fail to meet the requirements.

[0003] Currently, the heater is mainly cleaned manually, that is, after production is completed, the heater is disassembled, cleaned with a brush, and then installed again after cleaning. However, this method is inefficient and wastes manpower. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of low efficiency and waste of manpower in the manual cleaning of the heater in the prior art. The utility model provides a cleaning device that can automatically clean the heater after production is completed, and the cleaning process does not require the heater to be removed additionally, which simplifies the cleaning process, saves manpower, and improves the cleaning efficiency.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a cleaning device for cleaning the heater of the rehumidification machine, and the cleaning device comprises:

[0006] A water tank, which is provided with a water inlet and a water outlet;

[0007] A heating pipe is used to heat the water in the water tank. The heating pipe comprises an inner pipe and an outer pipe. The outer pipe is sleeved on the outside of the inner pipe. Both ends of the outer pipe and one end of the inner pipe are closed. A plurality of first silencer holes are provided on the circumferential surface of the inner pipe, and a plurality of second silencer holes are provided on the circumferential surface of the outer pipe.

[0008] A steam supply mechanism is connected to the other end of the inner tube and is used to supply steam into the inner tube;

[0009] The spray assembly comprises a water outlet pipe and at least one nozzle facing the heater, and two ends of the water outlet pipe are respectively connected with the water outlet and the nozzle.

[0010] By adopting the above technical scheme, after the production is completed, the water in the water tank is heated to a preset temperature by steam, and then the water outlet pipe delivers the water heated to the preset temperature to the nozzle to spray the heater to wash away the dirt on the surface of the heater. Compared with the manual cleaning method, the present application can not only save manpower and improve the cleaning efficiency, but also improve the cleaning effect by using hot water compared with cold water cleaning, thereby ensuring the heat transfer efficiency of the heater and making the temperature of the tobacco leaves meet the process requirements. At the same time, since one end of the inner tube is closed, after the steam enters the inner tube, the steam can only enter the outer tube from multiple first silencer holes, and then enter the water from the second silencer hole on the outer tube. In this way, the steam can be dispersed after passing through the first silencer hole and the second silencer hole successively, thereby reducing the amount of steam in each silencer hole, so as to reduce the volume of bubbles, prevent water splashing, and protect personal safety. In addition, the inner tube and the outer tube in the present application can play a role of blocking and dispersing the steam output outward twice, thereby reducing the propagation speed of the steam in the water and achieving the effect of reducing noise.

[0017] The first float valve includes a first float and a first valve body connected to each other. The first float is arranged in the water tank, and the first valve body is arranged on the water inlet pipe. The first float is used to detect whether the height of the water in the water tank is higher than a first preset height. When the height of the water in the water tank is equal to or higher than the first preset height, the first float drives the first valve body to close.

[0018] Optionally, a second float valve is further included, including a second float and a second valve body connected to each other, the second float is arranged in the water tank, the second valve body is arranged on the water inlet pipe, and the second float is arranged below the first float. The second float is used to detect whether the water level in the water tank is lower than a second preset height. When the water level in the water tank is lower than the second preset height, the second float drives the second valve body to open, wherein the second preset height is lower than the first preset height.

[0019] Optionally, a water pump is provided on the water outlet pipe, and the water pump is used to pump the water in the water tank to each nozzle.

[0037] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1As shown, the embodiment of the utility model discloses a cleaning device for cleaning the heater 24 of the dehumidification machine, and the cleaning device includes: a water tank 1, a heating tube 2, a steam supply mechanism 7 and a spray assembly 9. Among them, the water tank 1 is provided with a water inlet 25 and a water outlet 26, and the water tank 1 is used to hold cleaning water. Among them, the water inlet 25 is arranged above the water tank 1, and the water outlet 26 is arranged below the water tank 1. The heating tube 2 is used to heat the water in the water tank 1, and the heating tube 2 includes an inner tube 3 and an outer tube 4, and the outer tube 4 is sleeved on the outside of the inner tube 3, and both ends of the outer tube 4 and one end of the inner tube 3 are closed, and a plurality of first silencer holes 5 are provided on the circumferential surface of the inner tube 3, and a plurality of second silencer holes 6 are provided on the circumferential surface of the outer tube 4. The steam supply mechanism 7 is connected to the other end of the inner tube 3, and is used to pass steam into the inner tube 3. Specifically, a steam delivery pipe 8 is further provided between the steam supply mechanism 7 and the inner tube 3. A steam control valve 11 is provided on the steam delivery pipe 8. The steam control valve 11 is used to control the opening and closing of the steam delivery pipe 8. The steam is delivered to the inner tube 3 via the steam delivery pipe 8, and then the steam is discharged into the water tank 1 through the first silencer hole 5 and the second silencer hole 6 in sequence to heat the water in the water tank 1. The steam temperature provided by the steam supply mechanism 7 is 100°C. After a certain period of heating, the water in the water tank 1 can reach 70°C, so that the water in the water tank 1 can be used to clean the heater 24 of the rehumidifier. The spray assembly 9 includes a water outlet pipe 10 and at least one nozzle 27 facing the heater 24. The two ends of the water outlet pipe 10 are respectively connected to the water outlet 26 and the nozzle 27. When the production is completed, the cleaning water passes through the nozzle 27 to clean the surface of the heater 24 to flush away the dirt on the surface of the heater 24. Specifically, there are multiple nozzles 27, and the multiple nozzles 27 are arranged along the extension direction of the heater 24 (such as Figure 1 The two electrodes are arranged at equal intervals (as shown in the X direction in FIG).

[0039] By adopting the above technical solution, after the production is completed, the water in the water tank 1 is heated to a preset temperature by steam, and then the water outlet pipe 10 delivers the water heated to the preset temperature to the nozzle 27 to spray the heater 24 to remove the dirt attached to the heater 24. Compared with the manual cleaning method, the present application can not only save manpower and improve the cleaning efficiency, but also improve the cleaning effect by using hot water compared with cold water cleaning, thereby ensuring the heating efficiency of the heater 24. At the same time, since one end of the inner tube 3 is closed, after the steam enters the inner tube 3, the steam can only enter the outer tube 4 from the multiple first silencer holes 5, and then enter the water from the second silencer hole 6 on the outer tube 4. In this way, the steam can be dispersed after passing through the first silencer hole 5 and the second silencer hole 6 successively, thereby reducing the amount of steam in each silencer hole, so as to reduce the volume of bubbles, prevent water splashing, and protect personal safety. In addition, the inner tube 3 and the outer tube 4 in the present application can play a role of blocking and dispersing the steam output outward twice, thereby reducing the propagation speed of the steam in the water, and achieving the effect of reducing noise.

[0040] Alternatively, if Figure 1 As shown, it also includes a temperature sensor 12 and a control system (not shown in the figure). Among them, the temperature sensor 12 is arranged in the water tank 1, and the temperature sensor 12 is used to detect the temperature of the water in the water tank 1; the control system is electrically connected to the temperature sensor 12 and the steam control valve 11 respectively, and the control system is used to control the opening and closing of the steam control valve 11 according to the temperature detected by the temperature sensor 12. Specifically, when the temperature sensor 12 detects that the temperature of the water in the water tank 1 is equal to or higher than 70°C, the control system controls the steam control valve 11 to close; when the temperature sensor 12 detects that the temperature of the water in the water tank 1 is lower than 70°C, the control system controls the steam control valve 11 to open, so that steam continues to flow into the water tank 1 to heat the water in the water tank 1 until it is heated to 70°C to ensure the cleaning effect.

[0041] Alternatively, if Figure 1 As shown, the cleaning device disclosed in the present application also includes a water inlet pipe 23 and a first float valve. One end of the water inlet pipe 23 is connected to the water inlet 25, and the other end is connected to the cleaning water source. The first float valve includes a first float 13 and a first valve body 14 connected to each other. The first float 13 is arranged in the water tank 1, and the first valve body 14 is arranged on the water inlet pipe 23. The first float 13 is used to detect whether the height of the water in the water tank 1 is higher than the first preset height. When the height of the water in the water tank 1 is equal to or higher than the first preset height, the first float 13 drives the first valve body 14 to close to stop water inlet.

[0042] By adopting the above technical solution, a first float valve is provided to prevent the water in the water tank from being higher than a first preset height, thereby preventing the water level in the water tank 1 from being too high and overflowing, causing scalding to the operator.

[0043] Alternatively, if Figure 1 As shown, the second float valve is also included, including a second float 15 and a second valve body 16 connected to each other. The second float 15 is arranged in the water tank 1, and the second valve body 16 is arranged on the water inlet pipe 23. The second float 15 is arranged below the first float 13. The second float 15 is used to detect whether the height of the water in the water tank 1 is lower than the second preset height, wherein the second preset height is lower than the first preset height. When the height of the water in the water tank 1 is lower than the second preset height, the second float 15 drives the second valve body 16 to open to allow water to enter the water tank 1.

[0044] By adopting the above technical solution and setting a second float valve, the water in the water tank 1 can be prevented from being lower than the second preset height, thereby ensuring that there is always water in the water tank 1 and preventing the heating tube 2 from drying out.

[0045] Alternatively, if Figure 1As shown, a water pump 17 is provided on the water outlet pipe 10, and the water pump 17 is used to deliver the water in the water tank 1 to each nozzle 27 to increase the spraying pressure of the nozzle 27, thereby improving the spraying effect.

[0046] Alternatively, if Figure 1 As shown, the spray assembly 9 also includes an overflow pipe 18 and an overflow valve 19. The two ends of the overflow pipe 18 are respectively connected to the water inlet 25 and the water outlet pipe 10; the overflow valve 19 is arranged on the overflow pipe 18 to control the opening and closing of the overflow pipe 18. Specifically, when the water pressure in the cleaning water pipeline is too high, the overflow valve 19 opens, and the excess cleaning water returns to the water tank 1 through the overflow pipe 18 to protect the water pump 17 and the water outlet pipe 10.

[0047] Alternatively, if Figure 1 As shown, the heater 24 to be cleaned is arranged in the shell of the rehumidifier, and a sewage outlet 20 is provided at the bottom of the shell. The cleaning device also includes a sewage outlet 21 connected to the sewage outlet 20, and the sewage after cleaning is output through the sewage outlet 21.

[0048] Alternatively, if Figure 2 As shown, the inner tube 3 is provided with a plurality of axially extending inner tube 3 (such as Figure 2 The first muffler hole groups are arranged in equal intervals along the Y direction (as shown in FIG. 1 ), and each first muffler hole group includes a plurality of muffler holes arranged along the circumference of the inner tube 3 (as shown in FIG. 1 ). Figure 3 The outer tube 4 is provided with a plurality of second silencer hole groups which are arranged at equal intervals along the axial direction of the outer tube 4, and each second silencer hole group includes a plurality of second silencer holes 6 which are arranged at equal intervals along the circumference of the outer tube 4.

[0049] Specifically, Figure 2 As shown, the number of the first muffler hole group is equal to the number of the second muffler hole group and the positions correspond one to one, that is, the axes of the muffler holes in the first muffler hole group and the second muffler hole group corresponding to each other (for example Figure 2 Preferably, the number of second silencer holes 6 in a single second silencer hole group is greater than the number of first silencer holes 5 in a single first silencer hole group, so as to ensure that steam can enter the plurality of second silencer holes 6 close to the first silencer hole 5 after exiting the first silencer hole 5, so as to reduce the amount of steam entering the single second silencer hole 6, so that the steam can be dispersed again, thereby ensuring the silencer effect.

[0050] The cleaning device provided by the utility model can automatically clean the heater 24 after production is completed, and the heater 24 does not need to be removed during the cleaning process, which simplifies the cleaning process and improves the cleaning efficiency, thereby ensuring the normal operation of the heater 24.
