Description

Technical Field

[0001] The utility model relates to the field of sludge recovery and treatment technology, in particular to a portable sludge feeding frame. Background Art

[0002] Sludge is generally the sediment discharged from sewage treatment facilities. The sediment with organic matter as the main component is called sludge, which is easy to decompose and stink, has fine particles, small specific gravity (about 1.02-1.006), high water content and is not easy to dehydrate. It is a hydrophilic substance with a colloidal structure. According to the source of sludge, it can be divided into: water supply plant sludge, domestic sewage sludge, industrial sludge, and urban water body dredging sludge; according to the sewage treatment process of the sewage plant, sludge can be divided into: primary sedimentation tank sludge, activated sludge, humus sludge, chemical sludge; according to the stage of sludge production, it can be divided into: raw sludge, digested sludge, concentrated sludge, dehydrated sludge, and dried sludge.

[0003] In existing sludge treatment plants, ordinary material frames filled with sludge need to be manually poured into the sludge bin after transportation, which is inefficient. In addition, the drying effect of the sludge placed in the ordinary material frames is not ideal, thus affecting the overall production progress. Utility Model Content

When the two bottom plates are closed from both sides to the middle, the lower opening of the frame is closed, and the sludge is accommodated inside the frame and the louver baffles. When the two bottom plates are opened from the middle to both sides, the lower opening of the frame is opened for the sludge to be discharged; driven plates are installed near the bottom position on both sides of the frame, and a slide groove is provided on each driven plate. Fixed bolts are installed in the slide groove to connect the transmission plate so that the transmission plate slides along the slide groove, one end of the transmission plate is matched with the two bottom plates in a slot-type manner, and the other end of the transmission plate is rotatably connected with a striker assembly. When the striker assembly is subjected to a vertical upward force, the transmission plate is pushed to slide upward along the slide groove, so that the two bottom plates are separated from the transmission plate and open to both sides.

[0006] As a further technical solution, the impact rod assembly includes a U-shaped rod, connecting plates are arranged at both ends of the U-shaped rod and are rotatably connected to the corresponding transmission plate through connecting bolts; a sleeve is installed on the U-shaped rod, and a stabilizing plate is fixed on the outer wall of the sleeve for contacting and supporting the ground.

[0007] As a further technical solution, pin holes are provided at corresponding positions on the sleeve and the U-shaped rod for installing a latch pin to position the sleeve on the U-shaped rod.

[0008] As a further technical solution, two fixed plates are spaced apart at positions on the frame that are staggered from the sleeve, and pin holes are penetrated through the fixed plates. When the U-shaped rod rotates to enter between the two fixed plates, a pin is inserted into the pin holes of the two fixed plates to lock the U-shaped rod and the fixed plates.

[0009] As a further technical solution, two grooves are provided on the transmission plate, and a fixing pin is installed on each base plate for fitting into the grooves.

DETAILED DESCRIPTION

[0024] The utility model will be described in detail below with reference to the accompanying drawings:

[0025] Example: As shown in the attached Figures 1 to 6 As shown, the portable sludge feeding frame includes a louver baffle 1, a fixed plate 2, a driven plate 3, a fixing bolt 4, a striker assembly 5, a transmission plate 6, a fixing pin 7, a base plate 8, a frame 9, a lifting ear 10, a forklift ear 11, a U-shaped rod 12, a latch 13, a sleeve 14, a stabilizing plate 15, a connecting plate 16, a pin hole 17, a groove 18, a partition 19, a slide 20, a vent 21 and a connecting bolt 22.

[0026] Reference Figure 1 The upper and lower ends of the frame 9 are open, and shutter baffles 1 are installed around them. At the same time, a bottom plate 8 is hinged on both sides of the bottom of the frame 9. Figure 1 As shown, when the two bottom plates 8 are closed from both sides to the middle, the lower opening of the frame 9 is closed, and the sludge can be contained inside the frame 9 and the shutter baffle 1. Figure 3 As shown, when the two bottom plates 8 are opened from the middle to both sides, the lower opening of the frame 9 is opened for sludge discharge. Further, driven plates 3 are installed near the bottom of both sides of the frame 9, and each driven plate 3 is provided with a chute 20, which is arranged obliquely from the lower left to the upper right (such as Figure 4 As shown). A fixing bolt 4 is installed in the slide groove 20 to connect the transmission plate 6 so that the transmission plate 6 can slide along the slide groove 20. The transmission plate 6 is located above the bottom plate 8, as shown. Figure 4 As shown, the left end of the transmission plate 6 is slot-matched with the two bottom plates 8. Preferably, two grooves 18 are opened on the transmission plate 6, and a fixing pin 7 is installed on each bottom plate 8. When the two bottom plates 8 are in a closed state, the fixing pin 7 can be fitted into the groove 18.

[0027] like Figure 1 , 2As shown in Figure 3, the right end of the transmission plate 6 is rotatably connected with a striker assembly 5, and the striker assembly 5 includes a U-shaped rod 12, and a connecting plate 16 is arranged at both ends of the U-shaped rod 12, and the connecting plate 16 is rotatably connected to the corresponding transmission plate 6 through a connecting bolt 22. In addition, two sleeves 14 are first installed in the middle of the U-shaped rod 12, and then a stabilizing plate 15 is welded and fixed on the outer wall of each sleeve 14, and the stabilizing plate 15 can contact and support the ground. When the striker assembly 5 (stabilizing plate 5) is subjected to a vertical upward force, the U-shaped rod 12 pushes the transmission plate 6 to slide upward along the slide groove 20, so that the two bottom plates 8 are separated from the transmission plate 6 (the fixing pin rod 7 is separated from the groove 18) and then open to both sides. Preferably, the stabilizing plate 15 is made of 8mm thick steel plate material.

[0028] Reference Figure 5 , 6 Preferably, pin holes 17 are provided at corresponding positions on the sleeve 14 and the U-shaped rod 12, and the pin holes 17 are used to install the pins 13, so as to position the sleeve 14 on the U-shaped rod 12. Further, as Figure 2 , 3 As shown in FIG. 4, two fixing plates 2 are arranged at intervals at positions staggered from the sleeve 14 on the frame 9, and pin holes 17 are provided through the two fixing plates 2. When the U-shaped rod 12 rotates to enter between the two fixing plates 2, the latch 13 can be inserted into the pin holes 17 of the two fixing plates 2 to lock the U-shaped rod 12 and the fixing plates 2, preventing the striker assembly 5 from rotating downward, so as to facilitate the loading of sludge. The latch 13 of the sleeve 14 and the latch 13 of the fixing plate 2 can be used interchangeably.

[0029] like Figure 1 , 3 As shown, two partitions 19 are arranged at intervals on the inner wall of the frame 9, and two rows of vents 21 are provided on the shutter baffle 1 at positions corresponding to the partitions 19, so as to achieve a better sludge drying effect and facilitate the sludge feeding frame loaded with sludge to be pushed into the drying kiln for drying. Preferably, lifting ears 10 are provided on the four corners of the top of the frame 9, and forklift ears 11 are provided on both sides of the top of the frame 9, so as to facilitate the lifting of the feeding frame.

[0030] Working process of the utility model: When using the portable sludge feeding frame, the sludge transferred from the sludge plant and the sludge through the sludge scraper will enter the frame composed of the frame 9, the shutter baffle 1 and the bottom plate 8 from the entrance of the upper frame. The sludge enters the frame and passes through two shutter baffles 19, and the sludge in the frame is divided into three parts, and then the sludge feeding frame loaded with sludge is pushed into the drying kiln for drying. After drying, the material frame is pushed out, the U-shaped rod 12 is put down, and the material frame is lifted above the sludge bin and then hung down. When the stabilizing plate 15 contacts and sinks at the sludge bin feeding place, the supporting force of the stabilizing plate 15 is transmitted to the U-shaped rod 12. Since the U-shaped rod 12 is connected to the transmission plate 6 through the connecting plate 16 and the fixing bolt 4, the transmission plate 6 moves along the slide groove 20 of the driven plate 3, the fixing bolt 4 moves upward in the slide groove 20, and the other end of the transmission plate 6 moves downward, so that the fixing pin rod 7 of the bottom plate 8 is separated from the groove 18 of the transmission plate 6. At this time, the bottom plate 8 has no supporting force. Under the action of gravity, the sludge in the frame body knocks the bottom plate 8 open and discharges the sludge downward into the sludge bin.

[0031] The portable sludge loading frame loads sludge through the frame body. Since the louver baffle is provided with vents and two louver partitions are provided in the frame body, the drying speed of the sludge in the drying kiln is accelerated. During the loading process, the U-shaped impact rod assembly, the transmission plate and the bottom plate are used to realize that the sludge is discharged from the lower part of the frame body into the sludge bin during the falling process of the frame. There is no need for manual pouring, the efficiency of sludge loading is improved, and labor is saved, thereby reducing the operating cost for sludge treatment.

[0032] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
