Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to an embedded scraper conveyor for a filter press. Background Art

[0002] In the production process of lithium carbonate, the leaching and purification process is essential. The mother liquor rich in Li+ is separated from solid and liquid by a filter press, and the filter residue needs to be transported to a storage yard by a corresponding conveying device.

[0003] The current common conveying solution is to use a belt conveyor for conveying. Since the filter residue contains a high liquid content, it is difficult to completely clean the belt conveyor during cleaning, and some materials will leak onto the equipment installation platform, often requiring personnel to clean. This working condition not only causes environmental pollution but also increases the labor cost of the enterprise, and there are also potential safety hazards during personnel cleaning. To avoid this situation, an embedded scraper conveyor is also used. Since the residue contains liquid and the liquid contains corrosive substances, it will directly contact the shell of the embedded scraper conveyor, easily causing damage to the shell. To solve this problem, we propose an embedded scraper conveyor for a filter press. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that in the prior art, the liquid contains corrosive substances, which will directly contact the shell of the embedded scraper conveyor and easily cause damage to the shell, and to propose an embedded scraper conveyor for a filter press.

Side plates are fixedly connected to both ends of the bottom plate by T-bolts. Side plate liners are fixedly connected to the relative inner sides of the two side plates by T-bolts;

[0008] A middle connecting steel plate is fixedly connected to the scraper chain. A transition support plate is fixedly connected to the middle connecting steel plate. A scraper liner is fixedly connected to the transition support plate.

[0009] Preferably, the side plate liner, the scraper liner, and the bottom plate liner are all made of polytetrafluoroethylene material.

[0010] Preferably, support rods are fixedly connected to the two side plates, a guide rail support plate is fixedly connected to the support rods, and a return wear-resistant guide rail is arranged on the guide rail support plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Embodiment 1: Refer to Figures 1-3 , an en masse conveyor for a filter press, comprising a head assembly 1, a middle assembly 2 connected to the head assembly 1, and a tail assembly 3 connected to the middle assembly 2. The head assembly 1, the middle assembly 2, and the tail assembly 3 form a conveyor housing. A driving device 5 is fixedly connected to the conveyor housing. A scraper chain 4 is arranged inside the conveyor housing. The scraper chain 4 is a straight plate chain 23, and the scraper chain 4 is driven by the driving device 5.

[0022] The conveyor housing includes a bottom plate 28. A bottom plate lining 27 is fixedly connected to the bottom plate 28 by T-bolts 29. Both ends of the bottom plate 28 are fixedly connected to side plates 22 by T-bolts 29. Lining plates 21 of the side plates are fixedly connected to the relative inner sides of the two side plates 22 by T-bolts 29. The cover plate, the side plates 33, and the bottom plate 28 are all detachable. When replacing the lining plates, the side plates can be removed and replaced separately, which is convenient and fast. At the same time, since the lining plates are used to wrap and protect the conveyor housing, contact between the liquid and the housing is avoided, thereby preventing corrosion of the conveyor housing and being beneficial to extending the service life of the device.

[0023] A middle connecting steel plate 24 is fixedly connected to the scraper chain 4. A transition support plate 25 is fixedly connected to the middle connecting steel plate 24. A scraper lining 26 is fixedly connected to the transition support plate 25. The lining plates 21 of the side plates, the scraper lining 26, and the bottom plate lining 27 are all made of polytetrafluoroethylene material. Polytetrafluoroethylene has good non-stick properties, which is beneficial to preventing the adhesion of materials.

[0024] Support rods 30 are fixedly connected to the two side plates 22. A guide rail support plate 31 is fixedly connected to the support rods 30. A return wear-resistant guide rail 32 is arranged on the guide rail support plate 31. The support rods 30 increase the strength of the upper wear-resistant guide rail 32, and the guide rail support plate 31 and the wear-resistant guide rail 32 are lifted to increase the welding area between the guide rail support plate 31 and the support rods 30.

[0025] A transverse angle steel 33 is arranged at the feeding part of the conveyor housing. The transverse angle steel 33 not only increases the overall strength of the en masse conveyor, but also can break large pieces of materials falling from the upper part into small pieces, reducing the risk of the support guide rail being bent and avoiding the risk of material blockage caused by large pieces of materials.

[0026] The inclination angle of the conveyor housing is 0.3°, so that the moisture in the material can flow along the material conveying direction to the head after being squeezed out during the conveying process, and then be discharged from the head to the downstream equipment, avoiding the accumulation of moisture at the tail of the drag conveyor, thus preventing corrosion of the equipment and extending the service life of the equipment.

[0027] Embodiment 2: Refer to Figure 3 , as another preferred embodiment of the present invention, on the basis of Embodiment 1, the transverse angle steel 33 is made of stainless steel material.

[0028] The transverse angle steel 33 is rotatably connected to the inner wall of the conveyor housing through a pin shaft. A rotating disk 34 is fixedly connected to the pin shaft. A bolt 35 is threadedly penetrated through the rotating disk 34. A threaded hole is provided on the conveyor housing. The bolt 35 is threadedly connected to the threaded hole. Since there is residual material on the transverse angle steel 33, by loosening the bolt 35 and rotating the rotating disk 34, the transverse angle steel 33 can be driven to rotate to dump the material on the transverse angle steel 33.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
