Description

TECHNICAL FIELD

[0001] The utility model belongs to sewage treatment equipment field, especially relate to a filter plate subassembly for sewage treatment. BACKGROUND

[0002] The filter plate is an important component in the sewage treatment equipment, and after a long time of filtering work, the filter plate on the equipment often needs to be disassembled for cleaning or replacement. When the filter plate is disassembled and assembled, the equipment needs to be stopped, so the disassembly and assembly speed of the filter plate will directly affect the working efficiency of the equipment. The Chinese utility model patent with the authorization number CN220834407U discloses a sewage filtering and treatment equipment with a quick-assembly filter plate. The equipment includes a filter chamber and a filter plate body arranged in the filter chamber. The four corners of the filter plate are provided with limiting grooves. Four groups of mounting blocks are arranged in the filter chamber, and the filter plate body is located on one side of the mounting blocks. A reserved groove is formed in the mounting block. A pull rod passes through the reserved groove. A limiting block matched with the limiting groove is arranged on the end of the pull rod close to the filter plate body. A pressing plate is arranged in the reserved groove. One end of the pressing plate is connected with the pull rod. A reset spring is also arranged in the reserved groove. One end of the reset spring is connected with the reserved groove, and the other end is connected with the pressing plate.

[0003] When the filter plate body is installed, the pull rod on the mounting block is pulled first, so that the pressing plate presses the reset spring, the limiting block is stored in the reserved groove, then the filter plate body is placed on one side of the mounting block, and finally the pull rod is loosened, so that the limiting block is reset and inserted into the limiting groove under the action of the reset spring, thereby fixing the filter plate body in the filter treatment equipment body.

[0004] Compared with the traditional bolt fixing method, the operation method of the equipment disclosed in the above patent is relatively simple and fast, but there are still some deficiencies in actual application. Since the four groups of mounting blocks in the above patent are independently arranged, four pull rods need to be pulled at the same time to completely disconnect the limiting groove and the limiting block when disassembling and assembling the filter plate, and multiple people need to cooperate to operate. At the same time, since the four groups of mounting blocks correspond to the four corners of the filter plate respectively, the sewage in the equipment needs to be discharged before the filter plate is disassembled and assembled, so as to facilitate the operation of the pull rod at the bottom. The replacement efficiency of the filter plate is still relatively low. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of those skilled in the art, the utility model is described in further detail below in combination with the drawings and specific embodiments.

[0025] As Figure 1 , 2 , 3 shows, a filter plate assembly for sewage treatment, including filter plate 100 and two connecting strips 200 for connecting with sewage treatment equipment, two connecting strips 200 as the basis component of filter plate 100 installation, one side of connecting strip 200 is also provided with mounting portion 240, it is convenient for connecting strip 200 through the welding and bolt connection mode fixed in sewage treatment equipment. Two connecting strips 200 are located at the back of filter plate 100 two sides respectively, sealing strip 120 is arranged between filter plate 100 and connecting strip 200, sealing strip 120 is used to ensure the closed property of filter plate 100 two sides when filter plate 100 is connected with connecting strip 200, prevents impurities from passing through the gap between filter plate 100 and connecting strip 200. The back of filter plate 100 is provided with anti-drop groove 110, sealing strip 120 is installed in anti-drop groove 110, and anti-drop groove 110 can prevent sealing strip 120 from falling off, to avoid the influence on the installation and closed property of filter plate 100.

[0026] As Figure 2 ,4 The connecting strip 200 is provided with a through slot 201, and the through slot 201 is provided with a limiting block 220 sliding along the through slot 201. The back surface of the filter plate 100 is provided with a connecting plate 130 on both sides. The connecting plate 130 is provided with a limiting groove 131 matched with the limiting block 220. The limiting block 220 and the limiting groove 131 cooperate to fix the filter plate 100. One side of the connecting strip 200 is provided with a side plate 210, and the connecting strip 200 and the side plate 210 are provided with a hole channel 202. The hole channel 202 is provided with a rotating rod 230. One side of the limiting block 220 is provided with a rack 221, and the rotating rod 230 is provided with a gear 231. The hole channel 202 is expanded to have a containing cavity 203. The gear 231 is located in the containing cavity 203. The containing cavity 203 is communicated with the through slot 201. The gear 231 and the rack 221 are engaged at the communication position of the containing cavity 203 and the through slot 201. When the rotating rod 230 is installed, the side plate 210 is first opened, and then the rotating rod 230 is placed in the hole channel 202 between the connecting strip 200 and the side plate 210. The containing cavity 203 provides a placing space for the gear 231 and limits the axial movement of the gear 231, thereby preventing the axial movement of the rotating rod 230 and enabling the rotating rod 230 to stably rotate.

[0027] As shown in Figure 1 , 4 , 5, 6, the top end of the rotating rod 230 is provided with a rotating wheel 232. The rotating wheel 232 facilitates the rotation of the rotating rod 230 by the operator. The rotation of the rotating rod 230 can drive the displacement of the limiting block 220, thereby controlling the connection between the limiting block 220 and the limiting groove 131, achieving the purpose of quickly disassembling and assembling the filter plate 100. The inner wall of the bottom of the containing cavity 203 is provided with a locking protrusion 204 matched with the gear 231. When the rotating rod 230 is not rotated, the gear 231 is connected with the locking protrusion 204. At this time, the rotating rod 230 cannot be rotated. When the rotating rod 230 needs to be rotated, the rotating rod 230 is lifted upward to make the gear 231 and the locking protrusion 204 disengaged, so that the rotating rod 230 can be rotated. The cooperation between the locking protrusion 204 and the gear 231 can prevent the displacement of the limiting block 220 caused by the random rotation of the rotating rod 230, thereby improving the stability of the filter plate 100 after installation.

[0028] As shown in Figure 4 , 5As shown, the limiting groove 131 and the limiting block 220 are parallel to the filter plate 100, the distance between the limiting groove 131 and the filter plate 100 is less than the distance between the limiting block 220 and the filter plate 100, the end of the limiting block 220 and the notch of the limiting groove 131 are both provided with a matched abutting surface 222, the abutting surface 222 can make the limiting groove 131 smoothly inserted into the limiting groove 131. When the limiting block 220 is inserted into the limiting groove 131, the filter plate 100 will be displaced to the direction of the connecting strip 200, and then the sealing strip 120 between the filter plate 100 and the connecting strip 200 is extruded, the closing effect of the side edge of the filter plate 100 after installation is improved, the impurities are prevented from passing through the gap between the two sides of the filter plate 100, and the connecting stability of the filter plate 100 and the connecting strip 200 is improved. The connecting plate 130 is provided with a groove 132, the connecting strip 200 is provided with a convex strip 205 corresponding to the groove 132, the groove 132 and the convex strip 205 are matched, and the filter plate 100 is prevented from tilting to one side after the limiting block 220 and the limiting groove 131 are separated.

[0029] The above embodiments are the preferred implementation manners of the utility model, and are not the limitation of the utility model, and any obvious replacement without departing from the utility model concept of the utility model is within the protection scope of the utility model.
