DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The following is a further detailed description of an embodiment of a water supply and filtering pipeline and a water supply device of a moisture recovery system of a slice toaster according to the utility model in conjunction with the accompanying drawings.

[0031] On the one hand, if Figure 1As shown, the present application provides a water supply and filtration pipeline of the rehumidification system of a slice baking machine, which is used to be installed on the water supply device of the rehumidification system of the slice baking machine, and the mixed liquid is filtered through the water supply and filtration pipeline, and the mixed liquid that meets the process requirements is then transported to the ultrasonic high-pressure atomization nozzle through a water pump to achieve rehumidification.

[0032] Specifically, the water supply filtration pipeline includes a water outlet main pipeline 2 and a water outlet bypass pipeline 3 connected in parallel with each other. The water outlet main pipeline 2 is provided with a main pipeline filter 21 and a main pipeline stop valve 22 in sequence. The water inlet of the water outlet main pipeline 2 is used to communicate with the water storage tank 5, and the water outlet is used to communicate with the water pump 4; the water outlet bypass pipeline 3 is provided with a bypass pipeline filter 31 and a bypass pipeline stop valve 32 in sequence. The water inlet of the water outlet bypass pipeline 3 is used to communicate with the water storage tank 5, and the water outlet is used to communicate with the water pump 4.

[0033] It can be understood that both the water outlet main line 2 and the water outlet bypass line 3 can filter the mixed liquid flowing out of the water storage tank 5 to avoid insufficient pressure of the water pump 4 due to pipeline blockage. Since two water outlet pipelines connected in parallel are set in this example, only the water outlet main line 2 can be opened in use. When the main line filter 21 needs to be cleaned or replaced, the main line stop valve 22 is closed and the bypass line stop valve 32 is opened, so that the mixed liquid in the water storage tank 5 flows out from the water outlet bypass line 3 to the water pump 4, so that the filter can be replaced while ensuring the continuity of the mixed liquid outflow, solving the problem of discontinuous production operations during the replacement of the filter device.

[0034] Preferably, the connection point where the above-mentioned water outlet main line 2 and the above-mentioned water outlet bypass line 3 are connected in parallel is used to communicate with the above-mentioned water storage tank 5 through the water outlet connecting pipe 1, the above-mentioned main line stop valve 22 and the above-mentioned bypass line stop valve 32 are both close to the water inlet, and the above-mentioned main line filter 21 and the above-mentioned bypass line filter 31 are both close to the water outlet.

[0035] That is, the main line stop valve 22 and the bypass line stop valve 32 are both arranged at the upstream end of the mixed liquid flow direction, and the main line filter 21 and the bypass line filter 31 are both arranged at the downstream end of the mixed liquid flow direction. The advantage of such arrangement is that when the main line filter 21 or the bypass line filter 31 is disassembled, the main line stop valve 22 or the bypass line stop valve 32 is first used to block the outflow of the mixed liquid to avoid the spraying of the mixed liquid.

[0036] Furthermore, a cation exchange resin filter column is provided at the connection point between the outlet connecting pipe 1 and the water storage tank 5 to reduce the Fe content of the mixed liquid flowing out of the water storage tank 5 to the outlet main pipe 2 or the outlet bypass pipe 3. 3+ concentration.

[0037] It is understandable that although the water is softened in the boiler room, the water in the pipe and the iron pipe react with each other to produce a slightly acidic environment, which leads to Fe 3+ If the concentration is too high, the subsequent precipitation will form flocculent basic salts and clog the filter. Therefore, by setting up a cation exchange resin filter column, the Fe concentration in the water body can be reduced while ensuring the rewetting effect, avoiding the formation of sediments to clog the filter.

[0038] In some optional embodiments, the main line filter 21 is used to connect to the water pump 4 and a main line filter post-stop valve 23 is also provided on the pipeline, and the bypass line filter 31 is used to connect to the water pump and a bypass filter post-stop valve 33 is also provided on the pipeline.

[0039] It can be understood that the purpose of setting the main filter rear stop valve 23 and the bypass filter rear stop valve 33 is to prevent the water pump 4 from sucking air by disconnecting the pipeline and causing the mixed liquid to enter the gas when the main line filter 21 or the bypass line filter 31 is disassembled, cleaned or replaced. When in use, when the main line stop valve 22 is closed to replace or clean the main line filter 21, the main line filter rear stop valve 23 near the water pump 4 needs to be closed synchronously; when the bypass line stop valve 32 is closed to replace or clean the bypass line filter 31, the bypass filter rear stop valve 33 near the water pump 4 needs to be closed synchronously.

[0040] On the other hand, the present application also provides a water supply device for the moisture recovery system of a slice toaster, comprising a water storage tank 5, a water injection mechanism 6 and the above-mentioned water supply and filtration pipeline.

[0041] Specifically, the water tank 5 has a cavity for accommodating the mixed liquid; the water injection mechanism 6 is connected to the above-mentioned water tank 5; the water outlet main line 2 is provided with a main line filter 21 and a main line stop valve 22 in sequence, the water inlet of the above-mentioned water outlet main line 2 is connected to the water tank 5, and the water outlet is used to be connected to the water pump 4; the water outlet bypass line 3 is provided with a bypass line filter 31 and a bypass line stop valve 32 in sequence, the water inlet of the above-mentioned water outlet bypass line 3 is used to be connected to the water tank 5, and the water outlet is used to be connected to the water pump 4.

[0042] When in use, the water injection mechanism 6 injects the liquid to be mixed into the water tank 5, and then the liquid is mixed in the water tank 5 and flows out through the main water outlet line 2 or the bypass water outlet line 3, and is transported to the ultrasonic high-pressure atomization nozzle through the water pump 4 to achieve rehumidification.

[0043] Furthermore, if Figure 2 As shown, a filter screen 52 is provided in the water storage tank 5 to separate the cavity into a water inlet cavity and a water outlet cavity. The water injection mechanism 6 is connected to the water inlet cavity, and the water supply filter pipeline is connected to the water outlet cavity.

[0044] It can be understood that after the water injection mechanism 6 injects the liquid to be mixed into the water inlet chamber, it is initially filtered through the filter screen 52 and then flows into the water outlet chamber.

[0045] Preferably, the filter screen 52 is connected to the bottom wall of the water tank 5 through a steel plate, and the steel plate completely isolates the lower part of the water inlet chamber and the water outlet chamber, and the steel plate has a set height, so that after the mixed liquid enters the water inlet chamber, the sediment in the mixed liquid can be blocked by the steel plate and will not flow into the water outlet chamber from the filter holes of the filter screen 52.

[0046] In some optional embodiments, the connection between the water outlet connecting pipe 1 and the water storage tank 5 is located in the middle and lower part of the water outlet cavity. It should be noted that the water outlet connecting pipe 1 cannot be connected to the bottom of the water storage tank 5. The purpose of this arrangement is also to prevent the sediment that may enter the water outlet cavity from flowing out of the water outlet connecting pipe 1.

[0047] Preferably, a water level gauge 7 is also provided on the water storage tank 5, and the water level gauge 7 is signal-connected to the main line stop valve 22 and the bypass line stop valve 32, so as to close the main line stop valve 22 and the bypass line stop valve 32 when the water level in the water outlet chamber is lower than the set water level.

[0048] By setting the water level gauge 7 and connecting the main pipeline stop valve 22 and the bypass pipeline stop valve 32, the water supply filter pipeline will not have the problem of inhaling air. In combination with the above embodiment, the connection between the above water outlet connecting pipe 1 and the water storage tank 5 is located in the middle and lower part of the water outlet cavity, the above set water level should be higher than the height of the connection between the water outlet connecting pipe 1 and the water storage tank 5.

[0049] In some optional embodiments, a sewage pipe 53 is further provided at the bottom of the water storage tank 5, and the sewage pipe 53 is connected to the water inlet cavity.

[0050] It can be understood that the drain pipe 53 is for better discharging the sediment at the bottom of the water inlet chamber of the water storage tank 5. When the water storage tank 5 is cleaned, the drain pipe 53 can be used to discharge the sewage with the bottom sediment.

[0051] In some optional embodiments, one end of the water outlet connecting pipe 1 is connected to the lower part of the above-mentioned water storage tank 5, and the above-mentioned water injection mechanism 6 includes a condensate water inlet pipeline 61 and a soft water inlet pipeline 62, and the water outlets of the above-mentioned condensate water inlet pipeline 61 and the soft water inlet pipeline 62 are both connected to the upper part of the above-mentioned water storage tank 5.

[0052] It can be understood that the mixed liquid required by the present application is a mixture of condensed water and soft water, so the condensed water and soft water are respectively injected from the top of the water storage tank 5 using two independent pipelines. In other embodiments, corresponding pipelines can be installed according to the solution to be mixed, not limited to the two pipelines in the present application. However, it should be noted that in order to ensure that the solution is mixed completely and evenly, the height difference between the water injection mechanism 6 and the water supply and filtration pipeline should be large enough.

[0053] In this example, the water injection mechanism 6 is arranged on the top of the water tank 5 and is located on one side of the water inlet chamber, so that the mixed liquid directly enters the water inlet chamber and is mixed in the water inlet chamber. The mixed liquid enters the water outlet chamber after being filtered through the filter net 52, and flows out from the water outlet connecting pipe 1 after reaching the set water level.

[0054] In some optional embodiments, the condensate inlet pipeline 61 and the soft water inlet pipeline 62 both include a stop valve and a solenoid valve that are connected in sequence.

[0055] That is, the condensate water inlet pipeline 61 is provided with a condensate water stop valve 611 and a condensate water solenoid valve 612, and the soft water inlet pipeline 62 is provided with a soft water stop valve 621 and a soft water solenoid valve 622. The purpose of setting the stop valves is to better control the flow of condensate water and soft water into the water inlet chamber, and the solenoid valve can quickly control the start and stop of the inflow of condensate water and soft water.

[0056] Furthermore, a thermometer 8 is provided on the water tank 5 to measure the temperature in the water tank 5 and monitor the condition of the mixed liquid.

[0057] By means of the signals collected by the thermometer 8 and the water level meter 7, the mixing ratio of the condensed water and the soft water entering the water inlet chamber can be controlled to ensure that the mixed liquid meets the process standards.

[0058] Preferably, the water supply device also includes a control system for adjusting the opening and closing sizes of the condensate stop valve 611 and the soft water stop valve 621 according to the signals collected by the thermometer 8 and the water level meter 7 in combination with the control parameters to control the mixing ratio of the condensate and soft water entering the water inlet chamber.

[0059] In some optional embodiments, part of the top cover 51 of the water storage tank 5 can be flipped over to allow the cavity to communicate with the outside.

[0060] The flipped top cover 51 can be convenient for observing or cleaning the water storage tank 5. When it is necessary to open the top cover 51, it should be ensured that the top cover 51 completely seals the cavity to prevent the mixed liquid from being mixed with impurities.

[0061] In some optional embodiments, the water storage tank 5 is provided with a breathing valve 54 and an anti-overflow pipe 55 .

[0062] It can be understood that the breathing valve 54 is used to balance the pressure in the water storage tank 5. Since the cavity is sealed when the top cover 51 is closed, the pressure in the water storage tank 5 will change when condensed water and soft water are injected, and the pressure will also affect the quality of the mixed liquid. Therefore, the breathing valve 54 is provided. The overflow prevention pipe 55 is to prevent the liquid in the water storage tank 5 from being excessive and exceeding the calibrated volume.

[0063] In this example, the anti-overflow pipe 55 is connected to the side wall of the water tank 5 and is close to the top of the water tank 5; the breathing valve 54 is arranged at the top of the water tank 5 and is away from the flip-over top cover 51.

[0064] The working principle of the embodiment of the present application is as follows: open the main line stop valve 22 of the main water outlet line 2, and adjust the opening and closing degree of the condensed water stop valve 611 and the soft water stop valve 621 according to the ratio of the mixed liquid, and the condensed water and soft water enter the water inlet chamber through the top of the water storage tank 5 until the water level is higher than the set height of the steel plate, and then filter from the filter screen 52 and enter the water outlet chamber, so that the initial sediment of the mixed liquid will not enter the water outlet chamber. According to the signals collected by the thermometer 8 and the water level meter 7, adjust the opening and closing size of the condensed water stop valve 611 and the soft water stop valve 621 to control the mixing ratio of the condensed water and the soft water entering the water inlet chamber. After the mixed liquid rises to the set water level, it flows into the main water outlet line 2 through the water outlet connecting pipe 1, and after being filtered by the filter of the main water outlet line 2, it is transported to the ultrasonic high-pressure atomizing nozzle by the water pump 4 to achieve moisture regeneration. When the main line filter 21 needs to be cleaned or replaced, close the main line stop valve 22 and the main line filter rear stop valve 23, and open the bypass line stop valve 32 and the bypass filter rear stop valve, so that the mixed liquid no longer flows out from the outlet water main line 2, but flows out from the outlet water bypass line, so as to facilitate the replacement of the main line filter 21 and prevent the water pump 4 from sucking in the air in the disconnected line. When the bypass line filter 31 needs to be cleaned or replaced, refer to the above steps, close the outlet bypass line 3, and let the mixed liquid flow out from the outlet water main line 2.

[0065] The utility model discloses a water supply and filtering pipeline and water supply device of a rehumidification system of a slice baking machine. By setting two mutually parallel water outlet main pipelines 2 and water outlet bypass pipelines 3, when it is necessary to clean or replace the filter, there is another pipeline for the outflow of the mixed liquid, ensuring the continuity of the outflow of the mixed liquid, and solving the problem of discontinuous production operation during the replacement of the filter device; the main pipeline stop valve 22 and the bypass pipeline stop valve 32 are both arranged at the upstream end of the mixed liquid flow direction, and the main pipeline filter 21 and the bypass pipeline filter 31 are both arranged at the downstream end of the mixed liquid flow direction, so that when the main pipeline filter 21 or the bypass pipeline filter 31 is disassembled, the main pipeline stop valve 22 or the bypass pipeline filter 31 is first used to remove the main pipeline filter 21 or the bypass pipeline filter 31. The pipeline stop valve 32 blocks the outflow of the mixed liquid to prevent the mixed liquid from being sprayed; the stop valve 23 after the main filter and the stop valve 33 after the bypass filter are set to prevent the water pump 4 from sucking air by disconnecting the pipeline and causing the mixed liquid to enter the gas; by setting the filter mesh 52 and the steel plate with a set height at the bottom of the filter mesh 52, not only can the mixed liquid be filtered, but also the sediment can be prevented from entering the water outlet chamber; by setting the water level meter 7 and connecting it with the main pipeline stop valve 22 and the bypass pipeline stop valve 32 signals, the problem of air inhalation in the water supply filter pipeline can be avoided; by setting the breathing valve 54 and the anti-overflow pipe 55, it is used to balance the pressure in the water storage tank 5 to avoid excessive liquid in the water storage tank 5 exceeding the calibrated volume.
