[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] In order to solve the technical problem that the service life of the weighing system is shortened and the stability is insufficient due to the overall weighing of the filter residue and the filter press, the utility model provides a filter press weighing system that can achieve service life.

[0023] It should be noted that the filter press weighing system described in the present invention is used for but not limited to filter press weighing, etc. For the convenience of explanation, in the present invention, only a filter press weighing system applied to filter press weighing equipment is used as an example for explanation. The principle of applying a filter press weighing system to other types of equipment is essentially the same as the principle applied to filter press weighing equipment, and will not be described in detail here.

[0024] See also Figure 1 - Figure 2 , Figure 1 This is a structural schematic diagram of a filter press weighing system in one embodiment of the present invention, a filter press weighing system, including a base 100, a weighing assembly 200 and a lifting assembly 300; a gravity sensor 400 is provided on one side of the top of the base 100; the weighing assembly 200 and the top of the base 100 are connected by a telescopic part 500, and the gravity sensor 400 is located directly above the bottom of the weighing assembly 200; the lifting assembly 300 is provided on the other side of the top of the base 100, and a discharge port 310 is provided on the outer wall of the lifting assembly 300 facing away from the weighing assembly 200.

[0025] In this embodiment, an independent weighing system is constructed by setting up a weighing component 200, a lifting component 300 and a gravity sensor 400; further, the filter residue can be weighed in advance through the weighing component 200 and the gravity sensor 400, and then sent to the filter press by the lifting component 300, which can effectively avoid weighing the entire filter press and effectively ensure the stable use and normal service life of the weighing system.

[0026] In one embodiment, see Figure 1 The weighing assembly 200 includes a weighing box 210, a flip plate 220 and a first cylinder 230. The flip plate 220 is rotatably connected to the weighing box 210. The first cylinder 230 is arranged at the bottom end of the weighing box 210 and is used to drive one side of the flip plate 220 to flip downward toward the side of the lifting assembly 300. A feed door 240 that can be opened and closed is provided on the outer wall of the weighing box 210 close to the lifting assembly 300.

[0027] In this embodiment, after the filter residue is placed in the weighing box 210 , the weighing box 210 will move downward due to the contraction of the telescopic member 500 until it contacts the gravity sensor 400 to achieve weight sensing and counting.

[0028] In one embodiment, see Figure 1The flip plate 220 extends upward from one side of the lifting assembly 300 and forms a baffle 250 .

[0029] In this embodiment, the baffle 250 can allow the filter residue to move in one direction and accommodate more filter residue.

[0030] In one embodiment, see Figure 1 The top of the baffle 250 is provided with a chamfer 251 .

[0031] In one embodiment, see Figure 1 The gravity sensors 400 are arranged in pairs, and the two gravity sensors 400 are distributed along the two ends of the weighing component 200 respectively.

[0032] In this embodiment, the gravity sensors 400 are distributed along both ends of the weighing assembly 200 , so that the gravity sensors 400 can sense gravity changes in multiple directions, thereby improving the accuracy of detection.

[0033] In one embodiment, see Figure 1 , the gravity sensor 400 is set to a rectangular parallelepiped structure.

[0034] In this embodiment, the gravity sensor 400 is configured as a rectangular parallelepiped structure to increase the contact area with the weighing box 210 , thereby improving detection accuracy.

[0035] In one embodiment, see Figure 1 The lifting assembly 300 includes a lifting box 320 and a second cylinder 330. The second cylinder 330 is disposed at the bottom end of the lifting box 320 and drives the lifting box 320 to move up and down.

[0036] In this embodiment, after the filter residue is poured into the lifting box 320 through the weighing box 210, the lifting box 320 is driven by the second cylinder 330 to rise to the feed port of the filter press and discharge the residue.

[0037] In one embodiment, see Figure 1 The inner bottom of the lifting box 320 is provided with an inclined surface 340.

[0038] In this embodiment, the provision of the inclined surface 340 helps to gather the filter residue and reduce the loss of the filter residue during transportation.

[0039] In one embodiment, see Figure 1 A recess 110 is provided at one end of the top of the base 100 , and the recess 110 is located on the lower side of the weighing assembly 200 .

[0040] In this embodiment, the provision of the clearance groove 110 is mainly to prevent the first cylinder 230 from interfering with the base 100 .

[0041] In one embodiment, see Figure 1 The bottom end of the base 100 is provided with a supporting foot 120.

[0042] In order to better understand the present invention, the following Figures 1 to 2 The technical solution of the utility model is described in detail:

[0043] First, the filter residue is placed in the weighing box 210 and quantitatively tested. Next, the required weight of filter residue is transferred to the lifting box 320 via the feeding gate 240 under the flipping action of the flip plate 220. Next, the lifting box 320 is driven upward by the second cylinder 330 to the filter press's loading port, where the filter residue is discharged through the discharge port 310. This structure effectively avoids weighing the entire filter press, ensuring the stable operation and normal service life of the weighing system.

[0044] The above specific embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
