[0010] In order to more clearly understand the technical scheme of the utility model, the utility model is further explained below in conjunction with the drawings.

[0011] As Figs. 1-2The illustrated automatic monitoring device of a vertical disk filter includes a multifunctional range finder 3 and a vertical disk filter 1, the vertical disk filter 1 includes a vertical disk 2 and a baffle 4, the multifunctional range finder 3 is provided with two, and is fixedly installed at the baffle 4 on both sides of the vertical disk 2, the multifunctional range finder 4 includes an L-shaped bottom plate 6, a distance measuring sensor and a vertical support rod 8, the L-shaped bottom plate 6 is fixed on the baffle 4 through a screw 7, the vertical support rod 8 is fixed on the L-shaped bottom plate through a screw, the distance measuring sensor is integrated in a rectangular shell 9, the shell 9 is also integrated with a wireless signal transmitting device, the shell 9 is provided with a threaded hole at the bottom, the vertical support rod 8 is provided with an external threaded rod at the top, the external threaded rod cooperates with the threaded hole at the bottom of the shell, the multifunctional range finder 3 is connected with a control computer 5 through a wireless network, the control computer 5 includes a wireless receiving module, and an analysis software APP is installed in the control computer 5, the multifunctional range finder 3 collects the distance parameters between the vertical disk surfaces, and transmits the collected information to the control computer, the control computer also receives the parameters such as the negative pressure of the vertical disk and the blowback pressure collected by the vertical disk filter 1, the APP completes data collection and analysis, and establishes a big data model of main technical indexes during normal operation of the vertical disk.

[0012] The system data analysis and alarm working principle is as follows: the system takes the distance between the range finder and the two side vertical disk fan plates collected during daily shutdown as the reference, when the distance decreases by 1CM, it proves that the current filter cake thickness of the vertical disk is 1CM, then the average value of the current filter cake thickness per minute and per hour is obtained according to the average value of the data feedback by the range finder, and the disk surface speed and vacuum degree are adjusted in time according to the production needs, the vertical disk filter cake thickness is improved, the seed adding amount is optimized, and at the same time, according to the numerical value change feedback by the range finder, if the distance action deviation exceeds 5CM, it proves that the whole swing pair of the vertical disk fan plate is large, the system sends an alarm to the operator, the disk surface running condition is inspected in time, the failure rate is reduced, and the stable operation is ensured.

[0013] The economic benefit is calculated in the embodiment under the condition that two production lines have six vertical disk filters, and each line has two running and one standby:

[0014] Cloth changing labor saving:

[0015] Because three people are arranged to change filter cloth in the workshop every day, the labor cost is 260 yuan per person, the total number of filter cloth changing is about 20% of the total number of vertical disk filter cloth changing every year, and the labor cost can be saved by 260*3*365*20%=56940 yuan every year.

[0016] Filter plate saving: 400 filter plates need to be replaced every year from 2018 to 2023 due to filter plate deformation before the installation of the monitoring device, and a total of 30 filter plates are replaced in 2024. The unit price of a filter plate is 964.60 yuan per piece, and the annual filter plate cost can be saved by 370 pieces * 964.60 yuan per piece = 356,902 yuan.

[0017] The applicant uses 6 vertical disc filters, each with a total of 192 filter cloths. The normal replacement cycle of the vertical disc filter cloth is 3 months, and the annual cycle of cloth replacement is 4608 pieces. From 2021 to 2023, the vertical disc filter cloth is replaced by 5574 pieces on average due to filter cloth wear and tear. The number of filter cloths replaced each year is reduced by 966 pieces. After the installation of the device, there is no filter cloth wear and tear caused by large disc surface swing. The annual cost savings are 966 * 34 = 32,844 yuan (cost of filter cloth is 34 yuan per piece).

[0018] Total cost savings: 56940 + 356902 + 32844 = 446686 yuan.

[0019] The above is only a preferred embodiment of the present application, so any equivalent changes or modifications made in accordance with the structure, features and principles described in the patent application range of the present application are included in the patent application range of the present application.
