Description

Technical Field

[0001] This utility model relates to the field of catalyst production technology, and in particular to a catalyst carrier drying and distribution device. Background Technology

[0002] In the petroleum refining process, crude oil must undergo a series of processing steps to obtain various useful petroleum products. Petroleum refining involves cracking crude oil into fuels such as kerosene, gasoline, diesel, and heavy oil suitable for internal combustion engines, and producing chemical raw materials such as olefins and aromatics. Modern refineries are generally combined oil and chemical refineries, and these fuel oils mostly require refining through processes such as hydrogenation. Catalysts have become the core of these technological processes.

[0003] In catalyst production, the carrier production process directly affects the quality of the finished catalyst. Carrier production generally involves extruding alumina dry adhesive powder, binders, and extrusion aids into strips, followed by drying and calcination to obtain the catalyst carrier. Currently, in industrial continuous production equipment, the material extruded from the extruder falls directly into the drying belt, causing material to concentrate in localized areas, resulting in material accumulation, uneven material distribution, and affecting the drying effect. Manually rakeing the material can damage it, affecting the quality of the carrier and increasing labor costs.

[0004] Chinese patent CN203615721U discloses a material distribution device for catalyst drying. This device includes a conveyor belt, a conveyor pulley that drives the conveyor belt, and a drive shaft positioned below the belt, rotating under the drive of a variable frequency motor. A rotating turntable is mounted on the drive shaft, and a connecting rod is hinged to the turntable. The other end of the connecting rod is hinged to the conveyor belt. A belt swing shaft is also mounted on the conveyor belt. Although this type of solution solves the material distribution problem to some extent, the equipment is complex and occupies a large space, and the problem of material stacking and affecting the drying effect still exists.

[0005] Therefore, there is an urgent need for a catalyst carrier dryer that not only minimizes material stacking but also makes full use of the bandwidth of the drying belt, effectively reducing equipment space and cost while ensuring drying effect.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a catalyst carrier drying material distributor. By arranging a double extruder above both sides of the drying mesh belt and using the combination of the material distribution chute and the material distribution slide, the catalyst carrier material to be dried can be evenly guided onto the drying mesh belt, forming a double-zigzag and double-strip material distribution pattern on the mesh belt. This fully utilizes the bandwidth of the drying mesh belt, thereby ensuring the drying effect.

[0008] To achieve the above objectives, this utility model provides a catalyst carrier drying and distributing device for drying and distributing extruded catalyst carriers. It includes at least: a drying mesh belt, which is a conveyor belt structure driven by a mesh belt shaft; two extruders located above the drying mesh belt, with the two extruders positioned near their respective sides; two distributing chutes located between the two extruders and the drying mesh belt, the two chutes facing each other and corresponding to the two extruders respectively, the chutes capable of reciprocating inward from a vertical direction, causing a portion of the material guided by the two distributing chutes and scattered onto the drying mesh belt to form a double-zigzag shape; and two distributing slide plates located between the two extruders and the drying mesh belt, the two slide plates symmetrically arranged and corresponding to the two extruders respectively, each slide plate having an inwardly inclined guide baffle, causing another portion of the material from the two extruders to be diverted into two streams, which then scatter onto the drying mesh belt in a double-strip shape.

[0009] Furthermore, in the above technical solution, a connecting handle may be provided on the back of the fabric chute. The free end of the connecting handle is fixedly connected to the fabric chute, and the driving end of the connecting handle is connected to the drive motor. The drive motor drives the connecting handle and causes the fabric chute to swing.

[0010] Furthermore, in the above technical solution, the guide surfaces of the two fabric chutes can swing back and forth between an angle of 0° with the vertical plane and an inward tilt of 45°.

[0011] Furthermore, in the above technical solution, the fabric slide plate can have a first plate surface and a second plate surface, which can be connected by hinges to form a foldable configuration of two plates. The folding inner angle of the two plates is preferably 150° to 180°, which can be manually adjusted according to the amount of fabric to be dried. A telescopic support rod can be provided on the back of the second plate surface for manually adjusting the folding inner angle of the first and second plates.

[0012] Furthermore, in the above technical solution, the inward tilt angle of the guide baffle is preferably 10° to 45°.

[0013] Furthermore, in the above technical solution, the drive motor is preferably configured to be frequency-adjustable. The drive mechanism of the mesh belt shaft is preferably configured to be frequency-adjustable.

[0014] Furthermore, in the above technical solution, the preferred distance between the discharge ports of the two extruders is 120-180cm; the preferred effective material spreading width of the drying mesh belt is greater than the distance between the discharge ports.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1) This utility model arranges a double extruder on both sides above the drying mesh belt. Through the opposing and oscillating double material feeding chutes, a portion of the catalyst carrier material to be dried is evenly guided onto the drying mesh belt, forming a double-zigzag material distribution pattern. Symmetrically arranged double material feeding slides and guide baffles on the slide surfaces divide the remaining catalyst carrier material into two streams (one near the side of the mesh belt, the other near the center) and evenly guides them onto the drying mesh belt, forming a double-strip material distribution pattern. This double-zigzag + double-strip material distribution pattern maximizes the use of the mesh belt area and ensures full utilization of the mesh belt area and uniform material distribution, thereby guaranteeing the drying effect.

[0017] 2) This utility model can save labor and equipment costs, reduce energy consumption, and has the advantages of uniform fabric distribution, good drying effect and simple equipment.

[0018] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, and to make the above and other objects, technical features and advantages of this utility model easier to understand, one or more preferred embodiments are listed below and described in detail with reference to the accompanying drawings.

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0024] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0025] In this document, for ease of description, spatial relative terms such as “below,” “under,” “down,” “above,” “above,” “upper,” etc., are used to describe the relationship of one element or feature to another element or feature in the accompanying drawings. It should be understood that spatial relative terms are intended to encompass different orientations of an object in use or operation, in addition to those depicted in the figures. For example, if an object in the figure is flipped, an element described as “below” or “under” another element or feature would be oriented “above” that element or feature. Thus, the exemplary term “below” can encompass both the downward and upward orientations. An object may also have other orientations (rotated 90 degrees or other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0026] In this document, the terms "first," "second," etc., are used to distinguish two different elements or parts, and are not used to define specific positions or relative relationships. In other words, in some embodiments, the terms "first," "second," etc., can also be used interchangeably.

[0027] like Figure 1 , 2 As shown, this utility model provides a catalyst carrier drying and distributing device 1, which can be used to dry and distribute extruded catalyst carriers. It includes at least a drying mesh belt 11, a double extruder 12, double distributing chutes 13, and double distributing slides 14. The drying mesh belt 11 is a conveyor belt structure and is driven by a mesh belt shaft 111 (preferably, the drive mechanism of the mesh belt shaft 111 is frequency-adjustable). The double extruder 12 (i.e., two extruders 12) is located above the drying mesh belt 11, and the two extruders 12 are respectively positioned near the two sides of the drying mesh belt 11. The double distributing chutes (i.e., two distributing chutes 13) are located between the double extruders 12 and the drying mesh belt 11, and the two distributing chutes 13 are arranged opposite each other and respectively correspond to the two extruders 12 (located near the two sides of the dry mesh belt 11). Figure 2 Located slightly to the right of the extruder 12, the chute can reciprocate inward from the vertical direction, causing a portion of the material (i.e., material guided by the double fabric chute 13 and scattered onto the drying mesh belt 11) to fall onto the drying mesh belt. Figure 2The material from the right side of the extruder 12 is in a double-zigzag shape. The double feeding slides (i.e., two feeding slides 14) are located between the double extruder 12 and the drying mesh belt 11. The two feeding slides 14 are symmetrically arranged and correspond to the two extruders 12 respectively. Figure 2 (Slightly to the left of the center extruder 12), the two fabric slide plates 14 are each provided with inwardly inclined guide baffles 143 (see reference). Figure 1 This causes another portion of the material from the twin extruder 12 (i.e.) Figure 2 The material from the left side of the extruder 12 is split into two streams and scattered on the drying mesh belt 11 in a double strip shape.

[0028] This invention employs the aforementioned technical solution. By arranging a double extruder above both sides of the drying mesh belt, and using opposing, swingable double material feeding chutes, a portion of the catalyst carrier material to be dried is evenly guided onto the drying mesh belt, forming a double-zigzag material dispersion pattern on the mesh belt. Through symmetrically arranged double material feeding slides and guide baffles on the slide surfaces, another portion of the catalyst carrier material to be dried is divided into two streams (one near the side of the mesh belt, the other near the center) and evenly guided onto the drying mesh belt, forming a double-strip material dispersion pattern on the mesh belt. This double-zigzag + double-strip material pattern maximizes the utilization of the mesh belt area and ensures full utilization of the mesh belt area and uniform material distribution, thereby guaranteeing the drying effect. This invention saves labor and equipment costs, reduces energy consumption, and combines the advantages of uniform material distribution, good drying effect, and simple equipment.

[0029] Further as Figure 1 , 2 As shown, preferably but not limitingly, the fabric chute 13 has a connecting handle 131 on its back. The free end of the connecting handle 131 is fixedly connected to the fabric chute 13, and the driving end of the connecting handle 131 is connected to a drive motor 132. The drive motor 132 can drive the connecting handle 131 and cause the fabric chute 13 to swing. The drive motor is preferably frequency-adjustable. The guide surfaces (i.e., material contact surfaces) of the two fabric chute 13 swing back and forth between an angle of 0° with the vertical plane and an inward tilt of 45°. When the angle between the material contact surface and the vertical plane is 0°, the material falls directly onto the drying mesh belt 11. As the fabric chute 13 swings, the guide surface begins to contact the material and gradually guides the material towards the center of the mesh belt, thus forming a zigzag material shape on the drying mesh belt 11 within one swing cycle.

[0030] Further as Figure 1 , 2As shown, the fabric slide plate 14 has a first plate surface 141 and a second plate surface 142, which are connected by a hinge 144 to form a foldable configuration of the two plates. Preferably, but not limitingly, the folding inner angle of the two plates can be 150° to 180°, which can be manually adjusted according to the amount of dried fabric (i.e., production volume). Further, a telescopic support rod 145 is provided on the back of the second plate surface 142, which can be used to manually adjust the folding inner angle of the first plate surface 141 and the second plate surface 142. The manual adjustment here is to adjust the folding inner angle of the two plates to a suitable position when the production volume is determined. When the production volume is small, the folding inner angle can be adjusted to a larger angle (i.e., close to 180°), and when the production volume is large, the folding inner angle can be adjusted to a smaller angle (i.e., close to 150°). The guide baffle 143 is preferably disposed on the second plate surface 142, and the inward tilt angle of the guide baffle 143 is preferably 10° to 45°.

[0031] This invention allows for the mixing and extrusion of alumina dry adhesive powder, binder, and extrusion aid in a continuous production process using a double extruder 12. A portion of the extruded material 120 falls onto the drying mesh belt 11, forming a double-zigzag material dispersion pattern. The other portion is divided into two streams (one near the side of the mesh belt, the other near the center) and falls back onto the drying mesh belt 11, forming a double-strip material dispersion pattern. Both dispersion patterns fully utilize the area of ​​the drying mesh belt. The mesh belt shaft 111 drives the drying mesh belt 11 to uniformly transport the material into the drying oven for drying.

[0032] In the catalyst carrier production process, this invention employs continuous production equipment, with two extruders sharing a single carrier drying mesh belt, effectively improving production efficiency. The distance between the discharge ports of the two extruders 12 can be 120-180cm, and the effective material spreading width of the drying mesh belt 11 is preferably greater than the distance between the discharge ports, fully utilizing the width of the mesh belt. The combined use of double material spreading chutes and double material spreading slides can form a double-zigzag + double-strip material shape on the drying mesh belt, fully utilizing the width of the drying mesh belt, effectively solving the problem of uneven material spreading, greatly improving drying effect and efficiency, and the design is practical, simple, and reduces energy consumption.

[0033] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical applications, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. Any simple modifications, equivalent changes, and alterations made to the foregoing exemplary embodiments should fall within the protection scope of the present invention.
