Description

Technical Field

[0001] The utility model relates to the technical field of scraper devices, in particular to a steel wire scraper device with a wear-resistant sleeve. Background Art

[0002] Many filtering equipment such as rubber belt filters, belt filter presses, rotary drum filters, etc. need to remove the filter cake layer left on the filter cloth after completing a series of operations such as feeding, filtering, washing, and dehydration, so as to carry out the next step of filter cloth regeneration and enter a new cycle.

[0003] The traditional method is to use a scraper made of wear-resistant material to fit the surface of the filter cloth layer of the discharge roller. When the discharge roller rotates, the scraper will separate the filter cake from the surface of the filter cloth layer, and under the action of gravity, the filter cake falls to the bottom of the discharge roller to achieve discharge. The disadvantages of this method are:

[0004] In order to protect the filter cloth, most scrapers are made of non-metallic materials, which are relatively soft and easy to wear, requiring frequent adjustment and replacement.

[0005] Under the action of the filter cloth force, the discharge roller is prone to bending and deformation. The parts close to the support points on both sides are smaller, and the parts far from the support points in the center are larger. For large-sized filter equipment, this is more obvious due to the larger span of the support points on both sides. In addition, the plastic scraper itself deforms due to creep, especially when the temperature changes greatly. In this way, it is difficult for the plastic scraper, especially near the center of the discharge roller, to maintain a complete fit with the filter cloth and the roller surface, resulting in an increase in the thickness of the residual layer of the filter cake during discharge. In severe cases, it will affect the effect of filter cloth regeneration and the filtering performance of the equipment.

[0006] Therefore, it is necessary to design a more efficient and durable scraping device in the industry. Utility Model Content

[0007] In view of this, the utility model hopes to provide a steel wire scraper device with a wear-resistant sleeve, which does not require frequent adjustment and replacement of the scraper device, thereby further improving the performance of the filtering equipment.

[0008] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0009] The utility model provides a wire scraper device with a wear-resistant sleeve, comprising a bracket and a plurality of wire scraper assemblies; the wire scraper assembly comprises a spring, a tension adjuster, a wire clamp, and a steel wire; the outer edge of the steel wire is covered with a wear-resistant rubber sleeve, the spring is connected to the tension adjuster, the tension adjuster is connected to the wire clamp, and the wire clamp is connected to the steel wire; the wire scraper assembly is detachably connected to the bracket, each of the wire scraper assemblies is tiltedly installed, and a plurality of the wire scraper assemblies are evenly distributed on the bracket.

[0010] Furthermore, the material of the wear-resistant rubber sleeve is one of PVDF, silicone rubber and cow tendon, and the hardness of the wear-resistant rubber sleeve is 50-70 in Shore A.

[0011] Furthermore, the bracket includes a first cross bar and a second cross bar, the first cross bar is located at the upper part of the bracket, the second cross bar is located at the lower part of the bracket, one end of the wire scraper assembly is detachably connected to the first cross bar, and the other end is detachably connected to the second cross bar.

[0012] The beneficial effects of the utility model are as follows:

[0013] Each steel wire in the plurality of steel wire scraper assemblies of the utility model is appropriately pre-tightened and fits on the discharge roller, so there is no need to frequently adjust and replace parameters such as the position and tightness of the steel wire.

[0014] The utility model provides a spring in the steel wire scraper assembly. When the local filter cake layer is too thick or encounters foreign matter, the spring is stretched, and the fitting gap between the steel wire and the discharge roller is increased, thereby playing the role of buffering and protecting the filter cloth.

[0015] The fitting gap between the steel wire and the roller surface of the utility model varies very little with the bending deformation of the discharge roller, the wear of the steel wire and the ambient temperature. The steel wire scraper device discharges more thoroughly, the filter cloth regeneration effect is better, and the filtering performance of the equipment is improved.

[0016] The utility model has a wear-resistant rubber sleeve on the outer layer of the steel wire, which can prevent acid and alkali corrosion of the steel wire and avoid scratches and burrs caused by direct contact between the steel wire and the filter cloth. After the rubber sleeve is worn out after long-term use, it only needs to be re-inserted from the lower end of the steel wire, which is simple and convenient to operate.

[0020] 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.

[0021] like Figure 1 , Figure 2 As shown, a wire scraper device with a wear-resistant sleeve includes a bracket 7 and a plurality of wire scraper components; the wire scraper component includes a spring 1, a tension adjuster 2, a wire clamp 3, and a steel wire 5. The steel wire 5 is covered with a wear-resistant rubber sleeve 51. The material of the wear-resistant rubber sleeve 51 is one of PVDF, silicone rubber, and cow tendon. The hardness of the wear-resistant rubber sleeve 51 is 50-70 on the Shore scale.

[0022] One end of the spring 1 is connected to the tension adjuster 2. When the local filter cake layer is too thick or encounters foreign matter, the spring 1 is stretched and the fitting gap between the steel wire 5 and the discharge roller 4 increases. The other end of the tension adjuster 2 is connected to the wire clamp 3. The tension adjuster 2 can adjust the fitting gap between the steel wire 5 and the discharge roller 4 according to the different deflections of different parts of the discharge roller 4. The wire clamp 3 is connected to the steel wire 4.

[0023] The bracket 7 includes a first cross bar 71 and a second cross bar 72, the first cross bar 71 is located at the upper part of the bracket 7, and the second cross bar 72 is located at the lower part of the bracket 7. The wire scraper assembly is connected to the bracket 7, and one end of each wire scraper assembly is connected to the first cross bar 71, and the other end is connected to the second cross bar 72. Each wire scraper assembly is installed on the bracket 7 at an angle, and several wire scraper assemblies are evenly distributed on the bracket 7.

[0024] The wear-resistant rubber sleeve 51 on the outer layer of the steel wire 5 can not only prevent acid and alkali corrosion of the steel wire 5, but also avoid scratches and burrs caused by direct contact between the steel wire 5 and the filter cloth 6. After the wear-resistant rubber sleeve 51 is worn out after long-term use, it is only necessary to remove the steel wire scraper assembly from the bracket 7 and re-insert a new wear-resistant rubber sleeve from the lower end of the steel wire 5.

[0025] When the utility model is in use, the steel wire is appropriately pre-tightened and fits on the discharge roller. When the discharge roller rotates, it drives the filter cloth to move, and the steel wire separates the filter cake from the surface of the filter cloth layer. When the local filter cake layer is too thick or encounters foreign matter, the spring is stretched, and the fitting gap between the steel wire and the discharge roller is increased, which plays a role in buffering and protecting the filter cloth.

[0026] 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.
