For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] A sanitary slag discharge device, which can be constructed by Figures 1-3 is shown schematically. In the present embodiment, the sanitary slag discharge device comprises a valve body 1, a first butterfly plate 2, a second butterfly plate 3, a washing assembly and a verification assembly, wherein the valve body 1 is used to provide a containing space for the first butterfly plate 2 and the second butterfly plate 3, the washing assembly is used to perform washing work on the device, and the verification assembly is used to verify the washing effect and sterilization effect of the device.

[0028] Specifically, as shown in Figure 2 , the valve body 1 is internally provided with a sealing sleeve 4, and the first butterfly plate 2 and the second butterfly plate 3 are rotatably arranged in the sealing sleeve 4. The first butterfly plate 2 is located above the second butterfly plate, and a temporary storage cavity is formed between the first butterfly plate 2 and the second butterfly plate 3. When assembling, the staff can detachably install the top end of the valve body 1 to the slag discharge port at the bottom of the filter main body 9 through the flange, and respectively set independent driving devices (such as starting the actuator) for the first butterfly plate 2 and the second butterfly plate 3, so as to independently control the first butterfly plate 2 and the second butterfly plate 3 to act when cleaning, sterilization and verification are performed.

[0029] Optionally, in order to improve the sealing effect of the first butterfly plate 2 and the second butterfly plate 3 after entering the closed state, the outer diameters of the first butterfly plate 2 and the second butterfly plate 3 should be equal to the inner diameter of the sealing sleeve 4. At the same time, in order to avoid the action interference between the first butterfly plate 2 and the second butterfly plate 3, the spacing between the first butterfly plate 2 and the second butterfly plate 3 should be greater than the outer diameter of the first butterfly plate 2, so that the first butterfly plate 2 and the second butterfly plate 3 can be smoothly rotated.

[0030] In order to realize the cleaning work of the device, the cleaning assembly includes a cleaning pipeline 51 and two cleaning balls 52. As shown in Figure 1 and Figure 2 , the two cleaning balls 52 are arranged in the slag discharge port of the filter main body 9, and the two cleaning balls 52 are in communication with the cleaning pipeline 51, and the two cleaning balls 52 are respectively located on both sides of the first butterfly plate 2. When cleaning is needed, since the first butterfly plate 2 will directly contact the inside of the filter main body 1 during use, the staff can first drive the first butterfly plate 2 to enter the open state and make the second butterfly plate 3 enter the closed state, and then send cleaning liquid to the cleaning ball 52 through the cleaning pipeline 51. At this time, the two cleaning balls 52 can flush the two end faces of the first butterfly plate 2 at the same time, so that the first butterfly plate 2 obtains a full range of cleaning effect, avoiding the occurrence of cleaning dead angle on the first butterfly plate 2. After the cleaning work is completed, the staff can drive the second butterfly plate 3 to change to the open state, thereby emptying the cleaning waste liquid in the temporary storage cavity.

[0031] Correspondingly, when the device needs to be sterilized with steam, the staff should also first drive the first butterfly plate 2 to enter the open state and drive the second butterfly plate 3 to enter the closed state, and then send steam into the filter main body 9. At this time, the second butterfly plate 3 can block the steam to avoid the steam from escaping the device, so that the temperature and pressure around the first butterfly plate 2 meet the sterilization requirements, thereby the first butterfly plate 2 obtains good sterilization effect. After the sterilization work is completed, the staff should also drive the second butterfly plate 3 to change to the open state, thereby emptying the sterilization waste gas in the temporary storage cavity.

[0032] To facilitate the verification of the cleaning and sterilization effects of the device, the verification components include: a drainage pipe 6, an exhaust gas pipeline 7 and a waste liquid pipeline 8, wherein the first end of the drainage pipe 6 is connected to the end of the temporary storage cavity close to the second butterfly plate 3, the exhaust gas pipeline 7 and the waste liquid pipeline 8 are both connected to the second end of the drainage pipe 6, and a temperature sensor 71 is provided on the exhaust gas pipeline 7, and a conductivity meter 81 is provided on the waste liquid pipeline 8.

[0033] Optionally, to achieve communication between the drainage pipe 6 and the temporary storage cavity, the device may be provided with a first mounting hole on the side wall of the valve body 1, and a second mounting hole aligned with the first mounting hole may be provided on the side wall of the sealing sleeve 4. During assembly, a worker can insert the first end of the drainage pipe 6 into the temporary storage cavity along the first and second mounting holes, thereby facilitating the entry of waste liquid and waste gas from the temporary storage cavity into the verification assembly.

[0034] In order to improve the sealing effect near the drainage pipe 6, Figure 3 As shown, the drainage pipe 6 may include a threaded section 61 and a sealing section 62, wherein the sealing section 62 is located between the threaded section 61 and the first end of the drainage pipe 6. A locking nut 611 is provided on the threaded section 61, and a sealing ring 63 is also provided on the first end of the drainage pipe 6. It should be noted that the outer diameter of the sealing section 62 should be equal to the inner diameter of the second mounting hole, the outer diameter of the locking nut 611 should be larger than the inner diameter of the first mounting hole, and the outer diameter of the sealing ring 63 should be larger than the inner diameter of the second mounting hole. When the staff tightens the locking nut 611, the sealing ring 63 will fit tightly against the inner wall of the sealing sleeve 4, thereby achieving a good sealing effect between the drainage pipe 6 and the sealing sleeve 4.

[0035] Since the drainage pipe 6 is connected to the temporary storage cavity, during the cleaning process of this device, the cleaning waste liquid inside the temporary storage cavity will enter the waste liquid pipeline 8 along the drainage pipe 6 and eventually be discharged to the waste liquid collection device, thereby avoiding excessive accumulation of waste liquid inside the temporary storage cavity. At the same time, since a conductivity meter 81 is provided on the waste liquid pipeline 8, this device can detect the composition of the waste liquid during the cleaning process, thereby verifying the cleaning effect of the device. When the test results of the conductivity meter 81 meet the process requirements, it can be determined that the cleaning effect of the device meets the use requirements. At this time, the cleaning work can be stopped and the second butterfly plate 3 can be opened to drain the waste liquid.

[0036] Correspondingly, when the steam sterilization work is carried out, the sterilization waste gas in the temporary storage cavity also enters the waste gas pipeline 7 through the drainage connector 6, and is finally discharged to the waste gas collecting device, so as to avoid accidents caused by excessive pressure in the temporary storage cavity. At the same time, since the temperature sensor 71 is arranged on the waste gas pipeline 7, the device can detect the temperature of the waste gas during the sterilization process, so as to judge whether the temperature in the device meets the sterilization temperature requirement, and to verify the sterilization effect. When the detection result of the temperature sensor 71 meets the process requirement, it is determined that the sterilization effect of the device meets the use requirement, at which time the sterilization work can be stopped, and the second butterfly plate 3 is opened to discharge the waste gas.

[0037] In addition, the staff can also add a pressure sensor or other detection components (not shown in the figure) on the waste gas pipeline 7, so as to detect the steam pressure or other process parameters in the device after the detection result of the temperature sensor 71 meets the process requirement, so as to verify the sterilization effect of the device in all directions.

[0038] Optionally, in order to facilitate the flow direction of the waste gas and waste liquid in the verification component, and to facilitate the collection and discharge of the condensed water generated by the steam condensation, the device can be provided with a first control valve 72 and a drain valve 73 on the waste gas pipeline 7, and a second control valve 82 on the waste liquid pipeline 8. Specifically, the first control valve 72 should be located between the drain valve 73 and the second end of the drainage connector 6, the second control valve 82 should be located between the conductivity meter 81 and the second end of the drainage connector 6, and the temperature sensor 71 should be located between the first control valve 72 and the drain valve 73. When cleaning, the first control valve 72 should be closed and the second control valve 82 should be opened, so as to avoid the waste liquid entering the waste gas pipeline 7. Correspondingly, when sterilization is carried out, the second control valve 82 should be closed and the first control valve 72 should be opened, so as to avoid the waste gas entering the waste liquid pipeline 8, and to realize the collection and discharge of the condensed water through the drain valve 73.

[0039] As an optional embodiment of the present embodiment, in order to facilitate the smooth discharge of the residues in the candle filter to the collecting device, the device can also include a residue discharge short section 11. When assembling, the staff can detachably install the residue discharge short section 11 to the bottom end of the valve body 1 through the flange, and connect the residue discharge short section 11 with the collecting device, so as to ensure that the residues smoothly enter the inside of the collecting device.

[0040] The effects of the above scheme are described as follows:

[0041] The embodiment provides a sanitary grade residue discharging device, a cleaning assembly of which can perform omnibearing flushing on the first butterfly plate, and the cleaning effect of the first butterfly plate is improved.

[0042] The above merely describes preferred embodiments of the utility model and is not intended to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
