Description

Technical Field

[0001] The present disclosure belongs to the technical field of equipment cleaning, and particularly relates to a production equipment cleaning device. Background Art

[0002] Cigarette industrial enterprises are equipped with production equipment that requires circulating water cooling. Compressors and motors are installed in the production equipment. The above-mentioned equipment generates mechanical heat and requires cooling water to lower the temperature. After the cooling water absorbs heat, it enters the cooling tower and contacts the air to cool down. The hot cooling water dissipates heat into the air through the cooling tower. The cooled water can be reused. After long-term operation, the cooling water will absorb a large amount of dust in the air. The pipelines in the cooler of the production equipment are relatively thin, and impurities are likely to accumulate in the cooler. If the cooler is blocked, it will lead to insufficient water supply, and the heat generated by the compressor and motor cannot be taken away by the cooling water up to the standard, resulting in high temperature of the production equipment, leading to failures of the production equipment and affecting the production order. Summary of the Invention

[0003] The present disclosure proposes a production equipment cleaning device to solve the above technical problems.

[0005] In some embodiments, the ninth pipeline and the tenth pipeline are respectively connected to a sedimentation tank through fourth flange interfaces.

[0006] In some embodiments, a sewage discharge pipeline is connected to the bottom of the sedimentation tank, and a sewage discharge valve is arranged on the sewage discharge pipeline.

[0007] In some embodiments, the sedimentation tank is further connected to the eleventh pipeline, and a make-up water pump is arranged on the connecting pipeline between the sedimentation tank and the eleventh pipeline.

[0009] In some embodiments, the production equipment cleaning device is further provided with a standby flange interface.

[0010] Beneficial effects of the present disclosure: In the present disclosure, the controller determines whether the pressure difference exceeds the pressure difference threshold based on the pressure difference obtained from the pressure difference transmitter. If it exceeds, multiple electric valves are controlled to act in coordination to ensure that the cooling water in the cooling tower flushes the impurities in the cooler in the production equipment. Under normal circumstances, the electric valve opening may be smaller, but if it is found that the pressure difference threshold is exceeded, the opening of the electric valve will be increased to achieve the purpose of flushing the impurities in the cooler. The flushed impurities are finally transported to the sedimentation water tank, and the impurities are discharged from the drain valve. The cleaner cooling water in the sedimentation water tank is powered by the make-up pump and can be used again.

[0011] By flushing away the impurities in the cooler, it can further ensure that the cooling water flows smoothly in the cooler, taking away the heat that meets the standards, avoiding high temperature in the production equipment, and ensuring normal production order.

DETAILED DESCRIPTION

[0015] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0016] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0017] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be considered as part of the specification.

[0018] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0019] As Figure 1 shown, the controller first ensures that the production equipment is in a stopped state. After obtaining the stop signal and when it also obtains from the differential pressure transmitter 15 that the current differential pressure has exceeded the differential pressure threshold, it will then control the coordinated operation of each electric valve to ensure that the impurities in the cooler within the production equipment can be washed away. The differential pressure transmitter calculates the differential pressure through the first pressure sensor 8 and the second pressure sensor 14 and transmits the differential pressure to the controller. The specific description is as follows:

[0020] First, there are two ways to flush the production equipment. One is a forward flush, that is, in a clockwise manner, and the other is a reverse flush, that is, in a counterclockwise manner.

[0021] First, the forward flush method: The controller controls the second electric valve 5, the third electric valve 19, and the fifth electric valve 24 to close, and opens the first electric valve 4 and the fourth electric valve 20.

[0022] Cooling water flows out from the cooling water tower 31, passes through the first flange interface 2, and flows to the second pipeline 3. The cooling water in the second pipeline 3 flows into the first three-way valve 7 through the first electric valve 4. The first three-way valve 7 flows into the cooler within the production equipment through the fourth pipeline 9, the second flange interface 10, and the fifth pipeline 11, flushing the impurities in the cooler clean. The cooling water with impurities flows from the sixth pipeline 12 through the third flange interface 13 and the seventh pipeline 17 into the second three-way valve 16. The cooling water flows from the second three-way valve 16 into the fourth electric valve 20. The cooling water flows from the ninth pipeline 21 through the fourth flange interface 23 into the sedimentation tank 28. The impurities in the sedimentation tank 28 are discharged from the sewage valve 29. The relatively clean cooling water in the sedimentation tank 28 can enter the cooling tower 31 again for reuse.

[0023] Second, the reverse flush method: Close the first electric valve 4, open the second electric valve 5, open the fifth electric valve 24, open the third electric valve 19, and close the fourth electric valve 20. Please note that the cooling water going to the fifth flange interface 25 should be blocked. Therefore, there should be a sixth electric valve (not shown in the figure) on this branch, and the sixth electric valve should be closed.

[0024] The cooling water in the first pipeline 1 passes through the first flange interface 2, is transported through the second pipeline 3 to the twelfth pipeline 30, flows through the fifth electric valve 24 on the twelfth pipeline, passes through the eighth pipeline 18, flows through the third electric valve 19, then flows into the second three-way valve 16, passes through the seventh pipeline 17, and continues to pass through the third flange interface 13, passes through the sixth pipeline 12. The cooling water flows into the cooler in the production equipment, flushes the impurities in the cooler, and the cooling water with impurities flows out from the fifth pipeline 11, passes through the second flange interface 10, passes through the first three-way valve 7, the third pipeline 6, the second electric valve 5, the tenth pipeline 22, the fourth flange interface 23, and the sedimentation tank 28. Finally, the impurities are discharged from the sewage valve 29.

[0025] It should be supplemented that if the pressure difference does not exceed the standard, the cooling water can flow at the normal water flow rate. Specifically, it cannot reach the flushing speed and can ensure the normal operation speed of the cooler. The final cooling water flows into the cooling tower 31 from the fifth flange interface 25 and the eleventh pipeline 26.

[0026] The relatively clean water in the sedimentation tank 28 can, through the action of the make-up water pump 27, re-enter the cooling tower 31, thereby achieving the purpose of saving water.

[0027] With the production equipment cleaning device of the present disclosure, the impurities in the cooler in the production equipment are flushed by using forward and reverse flushing methods, flushing more cleanly, further ensuring that the cooling water can normally pass through the cooler, taking away the qualified heat, and ensuring the normal production order.

[0028] Please note that the present device is also provided with a standby flange interface, which can be used to connect with a tap water supply device, and the tap water is used to blow the impurities in the cooler in the production equipment.

[0029] It should be noted that in some embodiments of the present disclosure, by controlling the opening degree of the electric valve, the flow rate of the cooling water is ensured, so as to ensure that there is enough water to wash away the impurities. In addition, the flow rate of the cooling water can also be controlled by controlling the rotation speed of the water pump. Theoretically, both methods are feasible, and in some embodiments of the present disclosure, no specific limitation is made.

[0030] Although some specific embodiments of the present disclosure have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for the purpose of illustration and not for the purpose of limiting the scope of the present disclosure. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
