Description

Technical Field

[0001] The utility model relates to the technical field of filter devices, in particular to a lifting device for a vacuum box of a filter. Background Art

[0002] The horizontal rubber belt filter is a chemical equipment that can achieve rapid and continuous separation of solid and liquid. Under the action of vacuum, the slurry is separated into solid and liquid of filtrate and filter cake. The filtrate passes through the filter cloth and rubber belt and is collected in the vacuum box. The filtrate contains tiny particles. After the equipment has been running for a period of time, there will be scaling in the vacuum box. Increased scaling will affect the filtering effect. At this time, the vacuum box needs to be cleaned. At the same time, the friction belt on the vacuum box needs to be replaced after being worn for a period of time. When the existing lifting device is working, the vacuum hose connected to the vacuum box needs to be removed due to the descent angle problem, and the space for operators to inspect and repair is small after the vacuum box is lowered. Utility Model Content

[0003] In view of this, the utility model hopes to provide a lifting device for the vacuum box of the filter, which can move the vacuum box obliquely and lower it to a certain height, so as to facilitate cleaning and maintenance and reduce the intensity of manual operation and maintenance.

[0004] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0005] The utility model provides a lifting device for a vacuum box of a filter, comprising a cylinder, a connecting rod, a counterweight, a vacuum box support platform, and an intermediate fixed frame; the intermediate fixed frame is fixedly connected to a filter frame, one end of the connecting rod is connected to the vacuum box support platform, and the other end is connected to the counterweight, the connecting rod is respectively connected to the intermediate fixed frame and the cylinder, the vacuum box is detachably connected to the vacuum box support platform, and the vacuum box support platform is detachably connected to the filter frame.

[0006] Furthermore, the connecting rod is a straight rod.

[0007] Furthermore, the vacuum box and the vacuum box support are detachably connected via bolts, and the vacuum box support is detachably connected to the filter frame via bolts.

[0008] The beneficial effects of the utility model are as follows:

[0009] (1) The utility model adopts a cylinder to drive the connecting rod to rotate so as to quickly raise and lower the vacuum box, thereby reducing the intensity of manual operation and maintenance.

[0010] (2) When the vacuum box of the utility model is used to descend, the vacuum box descends obliquely, providing a wider operating space.

[0011] (3) When the utility model descending vacuum box is used for maintenance, there is no need to remove the vacuum hose, thereby improving the maintenance work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Among them: 1 is the cylinder, 2 is the connecting rod, 3 is the counterweight, 4 is the vacuum box support, 5 is the intermediate fixed frame, 6 is the frame, 7 is the vacuum box, and 8 is the vacuum hose. DETAILED DESCRIPTION

[0015] In order to more thoroughly understand the features and technical contents of the present invention, the implementation of the present invention is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not intended to limit the present invention.

[0016] like Figure 1-Figure 2 As shown, the utility model embodiment is a lifting device for the vacuum box of the filter, including a cylinder 1, a connecting rod 2, a counterweight 3, a vacuum box support 4, and an intermediate fixed frame 5; the connecting rod 2 is a straight rod, the intermediate fixed frame 5 is fixedly connected to the filter frame 6, one end of the connecting rod 2 is connected to the vacuum box support 4, and the other end is connected to the counterweight 3, the connecting rod 2 is rotatably connected to the intermediate fixed frame 5, the cylinder 1 is connected to the connecting rod 2 to provide power for the connecting rod 2, the vacuum box 7 is fixed to the vacuum box support 4 by bolts, and the vacuum box 7 is connected to the external main pipeline through a vacuum hose 8. When it is necessary to lift the vacuum box 7 When the vacuum box 7 is removed from the vacuum box support 4, the bolts can be removed. The vacuum box support 4 is detachably connected to the filter frame 6 by bolts. When the vacuum box 7 is working normally, the vacuum box support 4 is fixed to the frame 6 with bolts to increase stability. When the filter equipment needs to be repaired and the vacuum box 7 needs to be lowered, the bolts are removed and the cylinder 1 is started. Under the action of the cylinder 1, the connecting rod 2 swings, and the vacuum box support 4 drives the vacuum box 7 to move obliquely downward, which has a wider operating space, reduces the intensity of manual operation and maintenance, and does not need to remove the vacuum hose 8 when descending for maintenance, thereby improving the maintenance work efficiency.

[0017] One end of the connecting rod 2 of the utility model is connected to the counterweight 3. When the weight of the vacuum box 7 is large, after adding the counterweight 3, the power required to be provided by the cylinder 1 is reduced, and a smaller cylinder 1 can be used, thereby ensuring that the volume of the entire filter equipment is within the specified range.

[0018] Here, the specific models of the above-mentioned devices are not limited or described in detail, and the in-depth connection methods of the above-mentioned devices are not described in detail. As common knowledge, technicians in this field can understand it.

[0019] The embodiments of the utility model are only to introduce its specific implementation methods and are not intended to limit its protection scope. The technicians in this industry can make some modifications inspired by the embodiments, so any equivalent changes or modifications made in accordance with the scope of the utility model patent are within the scope of the claims of the utility model patent.
