[0030] Example 1

[0031] In this embodiment, an online purification device for water used in the stalk soaking process is disclosed. Figure 1 As shown, it includes a water outlet pipe, a water tank 3 and a water inlet pipe. A centrifuge 2 is arranged on the water outlet pipe. One end of the water outlet pipe is used to be connected with the sewage pipe of the stem soaking machine, and the other end is connected with the water tank 3. One end of the water inlet pipe is connected with the water tank 3, and the other end is used to be connected with the water inlet pipe of the stem soaking machine.

[0032] Specifically, the water outlet pipe includes a first water pipe and a second water pipe, one end of the first water pipe is connected to the water inlet of the centrifuge 2, and the other end is used to be connected to the sewage pipe of the stem soaking machine, one end of the second water pipe is connected to the water tank 3, and the other end is connected to the water outlet of the centrifuge 2, and the centrifuge 2 has the function of centrifugal impurity removal and purification of sewage, so that the water in the sewage pipe of the stem soaking machine can enter the water outlet pipe, and enter the water tank 3 for temporary storage after centrifugal purification by the centrifuge 2, and the water in the water tank 3 can enter the water inlet pipe of the stem soaking machine through the water inlet pipe, and then re-enter the stem soaking machine for soaking, and the water evolved from the centrifuge 2 is temporarily stored by the water tank 3, and the water flow in the buffer device is ensured to ensure that the water flow in the stem soaking machine and the device disclosed in this embodiment are in a state of dynamic balance.

[0033] In order to control the on-off of the water outlet pipe, a water outlet valve 1 is arranged on the water outlet pipe in this embodiment, and the on-off of the water outlet pipe is controlled by the water outlet valve 1. The water outlet valve 1 is in a normally open state when the stem soaking machine is working, and is closed when the stem soaking machine stops production.

[0034] Preferably, the water outlet valve 1 is connected to the first water pipe.

[0035] In order to allow the water in the water tank to enter the stem soaker through the water inlet pipe, the present embodiment is also connected to a water pump 11 on the water inlet pipe. When the stem soaker needs water for production, the water pump 11 is turned on to pump the water in the water tank 3 into the stem soaker through the water inlet pipe.

[0036] Since the soaking of tobacco stems will take away moisture, the total amount of water in the stem soaking machine and the water tank will gradually decrease. In order to ensure that the water in the stem soaking machine can meet the demand for soaking the stems, the present embodiment also arranges the water tank 3 to be connected with the water replenishment pipe 10, and connects the water replenishment valve 9 on the water replenishment pipe 10, so that water is replenished into the water tank 3 through the water replenishment pipe 10, and the replenished water meets the process requirements for water for soaking the stems.

[0037] In order to realize automatic water replenishment of the water tank 3, the present embodiment further provides a liquid level sensor in the water tank 3 for detecting the water level in the water tank 3. When the water level in the water tank 3 reaches the lower limit, the water replenishment valve 9 is automatically connected, and water is replenished into the water tank 3 through the water replenishment pipe 10. When the water level in the water tank 3 reaches the upper limit, the water replenishment valve 9 is automatically closed, and the water replenishment pipe 10 stops replenishing water into the water tank 3.

[0038] Preferably, the water supply valve 9 is a solenoid valve, and the lower limit of the water level is determined by the water level required when the stem soaker is working.

[0039] The liquid level sensor provided in the water tank 3 of this embodiment includes an upper liquid level gauge 6 and a lower liquid level gauge 7. The upper liquid level gauge 6 is used to detect whether the water level in the water tank 3 has reached the upper limit of the water level, and the lower liquid level gauge 7 is used to detect whether the water level in the water tank 3 has reached the lower limit of the water level. According to the water level status of the water tank 3, the on and off of the water supply valve 9 is controlled by the control system.

[0040] This embodiment detects the water level in the water tank by means of a liquid level sensor, and automatically replenishes the water tank according to the water level detection result, thereby ensuring that the water level in the water tank is always sufficient and that the problem of insufficient water in the stem soaking machine will not occur due to the tobacco stems soaking and taking away moisture.

[0041] The water tank of this embodiment adopts a double-layer water tank, and a steam chamber is arranged between the two layers of the water tank. The steam chamber is connected to the steam pipe. Steam is introduced into the steam chamber through the steam pipe, and then the steam is used to heat the water in the water tank, so that the water temperature in the water tank meets the use requirements of the stem soaking machine.

[0042] The steam chamber of this embodiment is also connected to a condenser, and the condensed water in the steam chamber is discharged through the condenser.

[0043] In this embodiment, a first valve 4 is provided on the steam pipe, and a second valve 8 is provided on the condenser pipe. The first valve 4 is used to control the on-off of the steam pipe, and the second valve is used to control the on-off of the condenser pipe.

[0044] Preferably, the first valve 4 is a solenoid valve, and the second valve 8 can be a rotary valve.

[0045] Specifically, the water tank includes an outer layer and an inner layer, a steam chamber is formed between the outer layer and the inner layer, the inner layer is used to hold water after centrifugation of the centrifuge 2, the outer layer is coated with an insulation layer, a steam inlet and a condensed water outlet are arranged on the steam chamber, the steam inlet is connected to the steam pipe, and the condensed water outlet is connected to the condensation pipe.

[0046] In order to realize automatic control of the water temperature in the water tank, the present embodiment further provides a temperature sensor 5 in the water tank, and the temperature sensor 5 is used to obtain the water temperature in the water tank. When the water temperature in the water tank is lower than the lower limit of the water temperature, the first valve 4 is opened, the steam pipe is connected, and high-temperature steam is introduced into the steam chamber of the water tank to heat the water in the water tank. When the water temperature in the water tank is greater than or equal to the upper limit of the water temperature, the first valve 4 is closed, the steam pipe is turned off, and the high-temperature steam is stopped from being introduced into the steam chamber of the water tank to stop heating the water in the water tank.

[0047] At the end of each day's production, the second valve 8 is opened to discharge the condensed water in the steam chamber, and then closed immediately after the condensed water is discharged.

[0048] Among them, the upper and lower limits of the water temperature are determined according to the process requirements of the stem soaking machine. By using steam to heat the water in the water tank in a timely manner, it can be ensured that the water temperature in the stem soaking machine will not fluctuate greatly due to the addition of lower or higher temperature purified water, thereby ensuring that the water temperature of the stem soaking machine always meets the process requirements and ensures product quality.

[0049] The present embodiment discloses an online purification device for water used in a stem soaking process, and the working process is as follows: after the stem soaking machine is started, the outlet valve 1 is opened, and the control system detects the temperature in the water tank 3 through the temperature sensor 5. If the temperature is lower than the lower limit of the water temperature, the first valve 4 is first started to heat the water in the water tank 3. When the water temperature meets the process requirements, the centrifuge 2 and the water pump 11 are started in sequence. The sewage pipe of the stem soaking machine is at the lower end of the stem soaking machine. The sewage in the stem soaking machine enters the centrifuge 2 from the sewage pipe through the outlet valve 1. The centrifuge 2 performs centrifugal purification and impurity removal on the sewage. The purified water flows into the water tank 3. The water temperature in the water tank 3 is controlled by the first valve 4, the temperature sensor 5 and the control system. Under the joint action of the control system, the water temperature is always within the required range of the stem soaking process water. The purified water in the water tank 3 is pumped away by the water pump 11 and flows back into the stem soaking machine. Since the tobacco stems absorb part of the water during the cleaning process in the stem soaking machine, the water levels in the stem soaking machine and the water tank 3 will continue to drop. When the water level in the water tank 3 drops to the position of the lower liquid level gauge 7, the control system opens the water supply valve 9, and the supplementary purified water enters the water tank 3 through the water supply pipe 10. When the water level in the water tank 3 reaches the position of the upper liquid level gauge 6, the control system closes the water supply valve 9, and repeats this process until the end of production. After the production is completed, the second valve 8 is opened to discharge the condensed water, and then closed after the discharge is completed.

[0050] The present embodiment discloses an online purification device for stem soaking process water, which removes impurities in the stem soaking process water by a centrifuge, thereby improving the water's permeability and further improving the water absorption and re-permeation effect of the tobacco stems; removing impurities in the stem soaking process water by a centrifuge can prevent sediment and other impurities from being deposited on the heating coil of the stem soaking machine, thereby improving the heating effect and reducing energy consumption; through the continuous purification, recycling and quantitative water replenishment of the stem soaking water, all the water in the system only needs to be replaced when the production is stopped for a long time, and the replacement frequency is greatly reduced, thereby achieving the effects of saving water, energy and improving production efficiency.
