具体实施方式detailed description
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
一方面，提供一种水处理格栅，如图3所示，包括边框5、安装在边框5之间的若干可拆卸的耙体6和驱动连接耙体6的驱动装置(未示出)，耙体6包括轴61和固定在轴61上的可拆卸的耙齿62，驱动装置驱动耙体6转动从而将被截留的固体通过耙体6依次递送至水处理格栅的上端。On the one hand, there is provided a water treatment grill, as shown in FIG. 3 , comprising frames 5, several detachable rakes 6 installed between the frames 5, and a driving device (not shown) for driving and connecting the rakes 6, The rake body 6 includes a shaft 61 and detachable rake teeth 62 fixed on the shaft 61 , and the driving device drives the rake body 6 to rotate so as to deliver the trapped solids through the rake body 6 to the upper end of the water treatment grid sequentially.
本发明中，每个耙体上可以较密地设置多组耙齿，从而该水处理格栅可以像现有技术一样能够顺利截留固体污染物。应用时，驱动装置驱动耙体转动，转动的耙体将被截留的固体依次递送至水处理格栅的上部，如图3所示，如果水处理格栅按图中所示方式倾斜设置，则每个耙体均按照图中左侧所示顺时针方向转动。位于下层位置的耙体上的耙齿能够把被截留的固体挑起来，然后递送给上层位置的耙体上的耙齿，从而依次将被截留的固体递送至水处理格栅的上端。In the present invention, multiple sets of rake tines can be arranged densely on each rake body, so that the water treatment grid can successfully trap solid pollutants as in the prior art. In application, the driving device drives the rake body to rotate, and the rotating rake body delivers the intercepted solids to the upper part of the water treatment grid in turn, as shown in Figure 3, if the water treatment grid is inclined as shown in the figure, then Each rake turns clockwise as shown on the left in the illustration. The tines on the rake body at the lower position can pick up the trapped solids, and then deliver them to the tines on the rake body at the upper position, so as to deliver the trapped solids to the upper end of the water treatment grill in turn.
本发明具有以下优点：The present invention has the following advantages:
(1)采用转动的耙体上的耙齿拨动固体的方式，格栅不再需要栅条，大大减轻了格栅的钢材使用量和重量；(1) The rake teeth on the rotating rake body are used to move the solid, so the grille no longer needs bars, which greatly reduces the amount of steel used and the weight of the grille;
(2)耙体可以从格栅上拆卸下来，耙齿可以从耙体轴上拆卸下来，零部件的固定不再依赖焊接，便于格栅及零部件的装卸和搬运；(2) The rake body can be disassembled from the grille, and the rake teeth can be disassembled from the rake body shaft. The fixing of parts no longer depends on welding, which is convenient for loading, unloading and handling of grilles and parts;
(3)耙齿和耙体的轴可以做成系列化的产品，便于批量生产，提高生产效率；(3) The rake teeth and the shaft of the rake body can be made into serialized products, which is convenient for mass production and improves production efficiency;
(4)便于格栅维护。(4) It is convenient for grid maintenance.
本发明中，耙齿可以分组或不分组，分组的耙齿一组齿可能有一个或多个。耙齿可以采用各种形状和安装方式，优选采用以下两种方式：In the present invention, the rake teeth can be grouped or not, and the grouped rake teeth may have one or more teeth. Rake teeth can adopt various shapes and installation methods, and the following two methods are preferred:
方式一：method one:
如图3和图4所示，耙齿62’可以为杆状，耙齿62’插接或通过螺钉连接在轴61’上。耙齿既可以是一端固定在轴上，另一端形成一个齿；也可以是耙齿中间固定在轴上，两端分别形成两个齿。As shown in Fig. 3 and Fig. 4, the rake teeth 62' can be rod-shaped, and the rake teeth 62' are plugged or connected to the shaft 61' by screws. One end of the rake teeth can be fixed on the shaft, and the other end forms a tooth; or the middle of the rake teeth can be fixed on the shaft, and two ends are formed respectively.
图5为图4所示实施例的运转过程示意图，为清楚的表示出对被截留固体进行递送的过程，图中仅示出了相邻两个耙体，且每个耙体上仅示出了一个耙齿。其中位置靠下的耙体上的耙齿从位置a1依次运转至a4，相对应的，位置靠上的耙体上的耙齿从位置b1运转至b4。从图中可以看出，当两个耙体的转速相同时，该两个耙齿所形成的夹角α1不发生变化，在该实施例中始终等于90度。Fig. 5 is a schematic diagram of the operation process of the embodiment shown in Fig. 4. In order to clearly show the process of delivering the trapped solids, only two adjacent rakes are shown in the figure, and each rake only shows a rake tine. The rake teeth on the lower rake body rotate from position a1 to a4 in sequence, and correspondingly, the rake teeth on the upper rake body rotate from position b1 to b4. It can be seen from the figure that when the rotational speeds of the two rake bodies are the same, the angle α1 formed by the two rake teeth does not change, which is always equal to 90 degrees in this embodiment.
如果被截留的固体中有铁丝、木棍等硬物，则固体在上下层耙体的耙齿上传递时可能会发生卡塞，为避免该问题，耙体的布置及转速选择优选使得：运转时在对被截留的固体进行递送的过程中相邻两个耙体上相交叉且起到递送作用的耙齿的夹角α1始终大于等于90度。这样可以使得下耙体上的耙齿所携带的固体能够顺利递送到上耙体上的耙齿，避免硬物卡在上下耙齿之间的情况。If there are hard objects such as iron wires and wooden sticks in the trapped solids, the solids may be jammed when they are passed on the teeth of the upper and lower rake bodies. At this time, in the process of delivering the trapped solid, the angle α1 between the intersecting rake teeth on two adjacent rake bodies and playing the role of delivery is always greater than or equal to 90 degrees. In this way, the solids carried by the tines on the lower rake body can be smoothly delivered to the tines on the upper rake body, avoiding the situation that hard objects are stuck between the upper and lower rake tines.
需要说明的是，当下耙体上的耙齿与上耙体上的耙齿开始交叉直至不再交叉时(参考图5中下耙齿从位置a2移动至a3，上耙齿从位置b2移动至b3)，在该过程中，该两个耙齿才会对被截留的固体起到递送作用。上述角度的限定是对该过程中起到递送作用的该相交叉的两个耙齿所形成的夹角的限定，对该过程以外上下耙体上相交叉的其他耙齿的夹角的情况不作限定。It should be noted that when the rake teeth on the lower rake body and the rake teeth on the upper rake body start to intersect until they no longer intersect (refer to Figure 5 where the lower rake teeth move from position a2 to a3, and the upper rake teeth move from position b2 to b3), in this process, the two rake tines will deliver the trapped solid. The limitation of the above-mentioned angle is the limitation of the angle formed by the two intersecting rake teeth that play a delivery role in this process, and does not make any limitation on the angles of other intersecting rake teeth on the upper and lower rake bodies other than this process. limited.
方式二：Method 2:
如图6所示，耙齿62”可以为三角形，耙齿62”的端部插接或通过螺钉连接在轴61”上。As shown in FIG. 6 , the rake teeth 62 ″ may be triangular in shape, and the ends of the rake teeth 62 ″ are inserted or connected to the shaft 61 ″ by screws.
如果被截留的固体中有铁丝、木棍等硬物，则固体在上下层耙体的耙齿上传递时可能会发生卡塞，为避免该问题，与上述同理，耙体的布置及转速选择优选使得：运转时在对被截留的固体进行递送的过程中相邻两个耙体上相交叉且起到递送作用的耙齿的前边沿所形成的夹角α2始终大于等于90度。If there are hard objects such as iron wires and wooden sticks in the trapped solids, the solids may be jammed when they are passed on the teeth of the upper and lower rake bodies. The selection is preferably such that: during operation, the angle α2 formed by the front edges of the intersecting rake teeth on two adjacent rake bodies that play a delivery role is always greater than or equal to 90 degrees during the delivery of the trapped solid.
本发明中，从图5和图6可以看出，为确保上述夹角大于等于90度，优选的，相邻两个耙体中位置靠上的耙体的转速大于等于位置靠下的耙体的转速。耙体可以本领域中各种可拆卸的方式安装在边框之间，例如手表的可伸缩销轴的方式，等等。In the present invention, it can be seen from Fig. 5 and Fig. 6 that in order to ensure that the above-mentioned included angle is greater than or equal to 90 degrees, preferably, the rotational speed of the upper rake among two adjacent rakes is greater than or equal to that of the lower rake. speed. The rake body can be installed between the bezels in various detachable ways in the art, such as the way of a retractable pin of a watch, and the like.
驱动装置可以为电机等，驱动装置可以设置在耙体的端部；每个耙体可以分别设置一个驱动装置，也可共用一个驱动装置。另外，边框可以为本领域技术人员能够想到的各种结构形式，例如方形框架，再例如一对条形支架(图3所示实施例即为该情况)，等等。The driving device can be a motor, etc., and the driving device can be arranged at the end of the rake body; each rake body can be provided with a driving device respectively, or can share a driving device. In addition, the frame can be in various structural forms that can be imagined by those skilled in the art, such as a square frame, or a pair of bar-shaped brackets (this is the case in the embodiment shown in FIG. 3 ), and so on.
另一方面，提供一种水处理系统，包括上述的水处理格栅，由于结构与上相同，此处不再赘述。On the other hand, a water treatment system is provided, including the above-mentioned water treatment grid. Since the structure is the same as above, it will not be repeated here.
又一方面，提供一种上述水处理格栅进行水处理的方法，使用时，与现有技术相同，水处理格栅倾斜设置；不同的是，本发明的设备启动时，优选使耙体从上至下依次开始转动，停止时，优选使耙体从下至上依次停止转动。这样能够进一步避免被截留的固体在上下层耙体的耙齿上传递时发生卡塞。In yet another aspect, a method for water treatment with the above-mentioned water treatment grid is provided. When in use, the same as the prior art, the water treatment grid is arranged obliquely; the difference is that when the equipment of the present invention is started, it is preferable to make the rake body from Start to rotate from top to bottom sequentially, and when stopping, preferably make the rake body stop rotating from bottom to top sequentially. This can further avoid jamming when the trapped solids are transferred on the tines of the upper and lower rake bodies.
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。The above description is a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
