no. 1 Embodiment approach 〕

[0031] (crusher with screen)

[0032] figure 1 It is a schematic explanatory drawing which shows the structure of the crusher with a filter provided with the filter device for crushers which concerns on 1st Embodiment of this invention.

[0033] The filter-equipped crusher 100 according to the first embodiment of the present invention is used to crush inclusions G contained in the water to be treated flowing through the water channel R. As shown in FIG. The filter-equipped crusher 100 of the present embodiment includes: a crusher 1 for crushing impurities G contained in the water to be treated flowing through the water channel R; and a filter device 2A for transferring the impurities G to the crusher 1 . The crusher 1 is arranged on one side of the screen device 2A. In addition, the crusher 1 and the screen device 2A are installed close to each other so as to straddle the water channel R. As shown in FIG.

[0034] The crusher 1 is used for crushing the inclusions G in the ...

no. 2 Embodiment approach 〕

[0088] Figure 5 It is a schematic explanatory drawing which shows the structure of the screen device for crushers concerning 2nd Embodiment of this invention.

[0089] In the screen device 2B for a crusher of the second embodiment, the rake 61 of the screen device 2A for a crusher of the first embodiment is replaced with a rake 65 including a first inclined surface 66a and a second inclined surface 66b. In addition, the description is abbreviate|omitted about the structure of the screen device 2B for crushers in this embodiment the same as the structure of the screen device 2A for crushers of 1st Embodiment.

[0090] When the rotary rake unit 6 is rotated in reverse, when the rake 65 is housed inside the screen 5 , foreign matter G may be caught by the rake 65 and brought into the screen unit 3 .

[0091] Therefore, if Figure 5 As shown, it is preferable to set the shape of the rake 65 as follows, that is, a first inclined surface 66a intersecting the outer peripheral surf...

no. 3 Embodiment approach 〕

[0102] Figure 7 It is a schematic explanatory drawing which shows the structure of the screen device for crushers concerning 3rd Embodiment of this invention.

[0103] In the filter screen device 2C for a crusher according to the third embodiment, as the screen part 30, a screen 7 having a long straight line part and a curved arc part arranged obliquely in the downstream direction; and a surrounding rake part 8, It has the chain 82 to which the rake 83 was attached, the two sprockets 81a and 81b for driving the chain 82, and the drive part 84. Note that, among the configurations of the screen device 2C for crushers according to the present embodiment, the description will be omitted for the same configuration as that of the screen device 2A for crushers according to the first embodiment.

[0104] The crusher 100 with a filter provided with the filter device 2C (the filter device 2C has the surrounding rake part 8 using a chain and a plurality of sprockets as the filter part ...

Abstract

The present invention addresses the problem of providing a screen device for a crusher and a method for operating the screen device for the crusher, whereby it is possible to detect the load of the screen device in a short time and to take appropriate measures for the overload state in the screen device for the crusher that transports inclusions such as residues in water to be treated to crush theinclusions. In order to solve the above problem, the present invention provides the screen device for the crusher and the method for operating the screen device for the crusher. The screen device forthe crusher transfers inclusions in a canal to the crusher for crushing inclusions, and comprises a screen unit for transferring inclusions; and a detection unit for detecting the current value of the drive unit for driving the screen unit. By detecting the current value of the driving part of the filter screen part, the overload state of the filter screen part can be judged instantly, so that itis possible to quickly take appropriate measures such as eliminating the overload state of the screen part.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2019-002986 filed on January 10, 2019. The entire contents of this Japanese application are incorporated herein by reference. technical field [0002] The present invention relates to a filter device installed in a water channel of a sewage treatment plant, etc., and transfers inclusions such as residues floating in the water to a crusher for crushing the inclusions, and an operating method of the filter device. More specifically, the present invention relates to a filter device and a filter device that uses a screen member to catch impurities such as residues floating in water, and uses a rotating rake to scrape the foreign matter captured by the screen member to a crusher. The method of operation of the network device. Background technique [0003] A crusher with a filter is installed in a water channel of a sewage treatment plant to crush impurities such as residues floating in the water. T...
