[0001] The present application relates to the technical field of wet slag removal process of a rotary kiln device in a hazardous waste incineration line, and in particular to a scraper for a slag remover. Background Art

[0002] The composition of industrial hazardous waste is complex and changeable. When incinerated, large pieces of slag and fine particles will be produced. When fine particles of slag accumulate, the scraper and the bottom plate of the slag remover will be stuck. When the material on the bottom plate is stuck with the scraper, it will cause scratches on the bottom plate, deformation of the scraper, and breaking of the connecting bolts of the transmission wheel. Eventually, the slag remover needs to be shut down for repair, which will affect the incineration production.

[0003] The existing scraper blade of the slag remover is an integral rigid structure. Due to errors in processing and assembly, the scraper blade cannot fully meet the requirement of close fit between the scraper blade and the bottom plate. In actual use, there will be a gap of about 3-5mm between the scraper blade and the bottom plate. At present, during operation, the slag remover may have an uneven bottom plate. The existing rigid structure scraper cannot fully fit with the bottom plate of the slag remover. The large pieces of slag and the volume difference of fine particles generated during incineration will affect the fit between the rigid scraper blade and the bottom plate. Due to the gap, materials will be stuck between the scraper blade and the bottom plate during operation, causing the incineration line to stop operating or operate at reduced load, affecting the processing capacity.

[0004] Based on this, a new technical solution is needed. Utility Model Content

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0022] It should be noted that various aspects of the embodiments within the scope of the appended claims are described below. It should be apparent that the aspects described herein can be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on the present application, it should be understood by those skilled in the art that an aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number and aspect described herein can be used to implement the device and / or practice the method. In addition, other structures and / or functionalities other than one or more of the aspects described herein can be used to implement this device and / or practice this method.

[0023] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0024] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0025] The existing scraper scraper is an integral rigid structure. Due to the errors in processing and assembly, the scraper cannot completely meet the requirements of close fit between the scraper and the bottom plate. In actual use, there will be a gap of about 3-5mm between the scraper and the bottom plate. Due to the gap, materials will be stuck between the scraper and the bottom plate during operation, causing the incineration line to stop operating or reduce load, affecting the processing capacity.

[0026] The design idea of ​​this scheme is to change the rigid scraper into a combination of a rigid scraper and a floating steel plate, and install the rigid scraper and the floating scraper together through spring pressure rods. The rigid scraper meets the strength requirements during operation, and the elastic scraper is basically in contact with or lifted up the bottom plate by floating, which can enhance the stability of equipment operation.

[0027] Based on this, this specification embodiment proposes a processing solution: Figure 1 and Figure 2 As shown, the embodiment of the present specification provides a scraper for a slag remover, including a rigid scraper 1 and a floating scraper 2. The floating scraper 2 is movably connected to the rigid scraper 1 through a spring pressure rod. A support guide plate group is provided on one side of the rigid scraper 1. The support guide plate group is provided with a through hole. The spring pressure rod includes a spindle 31, a nut 32, and a spring 33. The spring 33 is sleeved on the spindle 31. The spindle 31 passes through the through hole and is fixed to the nut 32. The floating scraper 2 is installed on the spindle 31 by bolts 7. The floating scraper 2 is pre-pressed to fit the bottom of the slag remover through the spring 33.

[0028] In some embodiments, the support guide plate group includes a first support guide plate 5 and a second support guide plate 6 , the first support guide plate 5 is provided with a threaded hole, and the second support guide plate 6 is provided with a through hole.

[0029] In some embodiments, the mandrel 31 is provided with an upper section and a lower section, the diameter of the lower section is larger than the diameter of the upper section, and the lower end of the mandrel 31 needs to bear the force received by the floating scraper 2 when working, so it needs to be larger than the diameter of the upper section to ensure the strength of the mandrel 31 and prevent deformation. The upper section of the mandrel 31 is provided with threads for installing the nut 32, and the spring 33 is placed between the gland 4 and the shaft shoulder.

[0030] In some embodiments, a gland 4 is fixed on the first support guide plate 5, and the upper section of the mandrel 31 passes through the gland 4 and is fixed with a nut 32. The gland 4 is provided with an external thread and a through hole, and the external thread is used to install the gland 4 on the first support guide plate 5. The gland 4 and its through hole play a guiding and limiting role, preventing the mandrel 31 from shifting in position during the floating process, and the mandrel 31 always keeps moving in the vertical direction.

[0031] In some embodiments, a groove is provided at the bottom of the core shaft 31, and the floating scraper 2 is fixedly installed in the groove and fixed by bolts 7. The floating scraper 2 can be assembled in pieces, which is convenient for disassembly and maintenance. When part of the floating scraper 2 is worn, only the floating scraper 2 at the corresponding position needs to be replaced, which can reduce the loss.

[0032] In some embodiments, the floating scraper 2 is installed on the rigid scraper through three groups of spring pressure rods, so as to improve the stability of the floating scraper 2 during operation.

[0033] In some embodiments, at least two groups of floating scrapers are provided on the rigid scraper, and the two adjacent groups of floating scrapers are staggered, which can be applicable to slag removers of more sizes.

[0034] In some embodiments, the inner wall of the slag scraper may have depressions or protrusions, and the total width of the rigid scraper 1 may be 50 to 55 mm smaller than the total width of the slag scraper to prevent the rigid scraper 1 from colliding with the inner wall of the slag scraper, causing deformation of the rigid scraper 1 or machine shutdown.

[0035] like Figure 3 As shown, in some embodiments, the gland 4 and the nut pre-press the floating scraper 2 to fit the bottom plate of the slag picker by 0 to 3 mm. Before the slag picker works, the initial position of the floating scraper 2 needs to be manually adjusted according to different bottom plate heights. The initial height of the floating scraper 2 can be adjusted by the nut 32. Generally, the distance between the floating scraper 2 and the bottom plate is most suitable between 0 and 3 mm. It should be noted that since the floating scraper 2 relies on the pressure applied by the spring 33 to achieve fit with the bottom plate, the spring 33 needs to be in a compressed state at all times. It may be necessary to select the corresponding spring 33 according to the size of the slag picker. The floating stroke of the floating scraper 2 can be within 5 mm.

[0036] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the product embodiment described later, since it corresponds to the method, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiment.
