Description

Technical Field

[0001] The utility model relates to the technical field of catalyst preparation, in particular to a solid-liquid separation mechanism for catalyst preparation. Background Art

[0002] A catalyst generally refers to a substance that increases the reaction rate without changing the overall standard Gibbs free energy of the reaction. It can also be described as a substance that increases the reaction rate without altering the chemical equilibrium, and whose mass and chemical properties remain unchanged before and after the reaction. According to statistics, catalysts are used in over 90% of industrial processes, including those in the chemical, petrochemical, biochemical, and environmental protection industries.

[0003] like Figure 3 As shown, this is the solid-liquid separation mechanism used on the previous generation of catalyst preparation equipment. Its main function is to perform solid-liquid separation operations on the processed raw materials, so as to facilitate the subsequent processing operations of the catalyst. However, the solid-liquid separation mechanism of this structure has the following shortcomings in actual use: First, the original feed pipe is installed on the box cover, and its tail end is vertically downward toward the middle of the inclined screen plate. The raw materials entering through the feed pipe will be unevenly scattered on the inclined screen plate, causing part of the solid catalyst to continue to adhere to the inclined screen plate and cannot be effectively guided into the collection box. Secondly, the collection box structure is relatively small and is flush with the inclined surface of the inclined screen plate. In actual use, the filtered solid catalyst will be concentrated and accumulated between the inclined screen plate and the collection box. The solid catalyst discharge process is prone to jamming and obstruction. It is necessary to continue to use flushing liquid to flush and discharge the solid catalyst. The actual use is less convenient and the efficiency is low.

[0004] In view of this, it is particularly important to design and manufacture a solid-liquid separation mechanism that can reduce the adhesion of solid catalysts on the inclined screen plate and ensure smooth and stable discharge process, which is used in the catalyst preparation process. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the solid catalyst is easily attached to the inclined screen plate and affects the normal operation of the separation mechanism, and the material is easily stuck during the discharge process in the traditional solid-liquid separation mechanism for catalyst preparation.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A solid-liquid separation mechanism for catalyst preparation comprises a box body, a box cover detachably mounted on the upper end of the box body by quick-release screws, an inclined screen plate mounted on the inner side of the box body, a feed pipe arranged at the left end of the box body, and a liquid outlet pipe connected to the lower end of the box body; a diversion portion is provided between the right end of the feed pipe and the left end of the box body for the raw materials to move from left to right along the inclined surface of the inclined screen plate after entering the box body; and a gathering portion is provided at the right end of the box body for the centralized collection and discharge of solids after separation.

[0008] As a further description of the above technical solution:

[0009] The diversion part includes a distribution hopper which is obliquely fixed on the right end of the feed pipe with the right end facing the inclined screen plate, and a plurality of distribution partitions which are equidistantly fixed on the discharge port at the right end of the distribution hopper.

[0010] As a further description of the above technical solution:

[0011] The distribution hopper is in the shape of an isosceles trapezoidal structure, and the inner cavity of the distribution hopper gradually increases from left to right.

[0012] As a further description of the above technical solution:

[0013] The material collection part includes a material collection box connected to the middle of the right end of the box body and flush with the upper end surface of the inclined screen plate, a discharge valve connected to the middle of the lower end of the material collection box, a valve block rotatably installed in the middle of the discharge valve, a handle installed at the front end of the valve block and a liquid discharge part arranged between the box body and the material collection box.

[0014] As a further description of the above technical solution:

[0015] The liquid discharge portion comprises a return pipe obliquely connected between the right end of the box body and the left end of the collecting box, and a microporous filter installed on the inner side of the right end of the return pipe.

[0016] As a further description of the above technical solution:

[0017] The lower end of the box body is symmetrically fixedly connected to two mounting brackets in an L-shaped structure, and mounting holes are opened on the horizontal ends of the mounting brackets.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] In the utility model, the original solid-liquid separation mechanism is scientifically and rationally improved, and a dividing hopper and a dividing partition are set between the feed pipe and the left end of the inclined screen plate. The raw materials entering through the feed pipe can move evenly downward along the inclined surface of the inclined screen plate under the action of the dividing hopper and multiple dividing partitions. The liquid flowing along the inclined screen plate can flush the solid catalyst downward into the collection box. At the same time, the collection box is enlarged and its structure is improved. The solid catalyst can enter the collection box along the inclined surface of the inclined screen plate, and then fall into the space between the right end of the collection box and the discharge valve. When the discharge valve is opened, the solid catalyst can be discharged vertically downward through the discharge valve under the action of gravity. This structure can guide the solid catalyst attached to the inclined screen plate to be flushed into the dividing hopper, which can reduce the problem of solid catalyst continuously adhering to the inclined screen plate and affecting the normal operation of the separation mechanism. At the same time, the improved collection box structure is not prone to problems of material jamming and obstruction, thereby improving the stability of the solid-liquid separation mechanism.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-3The utility model provides a technical solution: a solid-liquid separation mechanism for catalyst preparation, comprising a box body 1, a box cover 2 detachably mounted on the upper end of the box body 1 by means of quick-release screws 201, an inclined screen plate 3 mounted on the inner side of the box body 1, a feed pipe 4 arranged at the left end of the box body 1 and a liquid outlet pipe 5 connected to the lower end of the box body 1, a diversion portion for the raw material to move from left to right along the inclined surface of the inclined screen plate 3 after entering the box body 1 is provided between the right end of the feed pipe 4 and the left end of the box body 1, and a gathering portion for collecting and discharging solids after separation is provided at the right end of the box body 1.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the diversion part includes a dividing hopper 401 which is obliquely fixed at the right end of the feed pipe 4 and the right end is facing the inclined screen plate 3, and a plurality of dividing partitions 402 which are equidistantly fixed on the discharge port at the right end of the dividing hopper 401. The dividing hopper 401 is shaped as an isosceles trapezoidal structure, and the content cavity of the dividing hopper 401 gradually increases from left to right. This structural setting can divide a single stream of liquid containing a solid catalyst into multiple streams, and then enable the multiple streams of liquid containing a solid catalyst to move downward from left to right along the inclined surface of the inclined screen plate 3 in multiple directions, so that the solid-liquid mixed raw materials can contact the inclined screen plate 3 in multiple directions, thereby ensuring the stability and efficiency of solid-liquid separation, and at the same time, it can generate kinetic energy to flush the solid catalyst into the inside of the collection box 6, to prevent the solid catalyst from continuing to accumulate locally on the inclined screen plate 3.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the collecting part includes a collecting box 6 connected to the middle of the right end of the box body 1 and flush with the upper end surface of the inclined screen plate 3, a discharge valve 7 connected to the middle of the lower end of the collecting box 6, a valve block 701 rotatably installed in the middle of the discharge valve 7, a handle 702 installed at the front end of the valve block 701 and a liquid discharge part arranged between the box body 1 and the collecting box 6.

[0029] Among them, the drainage part includes a reflux pipe 8 obliquely connected between the right end of the box body 1 and the left end of the collection box 6 and a microporous filter 801 installed on the inner side of the right end of the reflux pipe 8, which can filter the liquid entering the collection box 6. The filtered liquid can be returned to the box body 1 through the reflux pipe 8, and the filtered solid catalyst can be collected between the collection box 6 and the discharge valve 7.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, two L-shaped mounting brackets 101 are symmetrically fixedly connected to the lower end of the box body 1, and mounting holes 102 are provided on the horizontal ends of the mounting brackets 101. The arrangement of the mounting brackets 101 and the mounting holes 102 facilitates the installation and fixation of the box body 1 as a whole to the separation station of the catalyst preparation device through fasteners.

[0031] Specifically, such as Figure 1-3 As shown, the collection box 6 is a two-stage structure. The left half of the collection box 6 is tilted and flush with the upper end surface of the inclined screen plate 3, which can ensure that the solid catalyst can stably enter the collection box 6 and prevent the solid catalyst from accumulating between the inclined screen plate 3 and the collection box 6. The right half of the collection box 6 is vertically set, and the lower end is a lock setting. When the discharge valve 7 is opened, the solid catalyst collected between the collection box 6 and the discharge valve 7 can be discharged from the collection box 6 through the discharge valve 7 under the combined action of gravity and contact force. Compared with Figure 3 The oblique setting of the previous generation makes the discharge operation smoother and is less likely to cause material jamming during the discharge process.

[0032] Working principle: When in use, the solid-liquid mixed raw material processed in the previous process can enter the box 1 through the feed pipe 4. The dividing hopper 401 and multiple dividing partitions 402 between the feed pipe 4 and the box 1 can divide a single stream of liquid containing solid catalyst into multiple streams, and then evenly move along the inclined surface of the inclined screen plate 3 from left to right. Since the solid catalyst cannot pass through the inclined screen plate 3, it can be rushed into the collection box 6 along the inclined surface of the inclined screen plate 3 under the action of liquid flow. When the solid catalyst enters the collection box 6, The liquid flows along the inclined surface at the left end of the collecting box 6 into the vertical storage space at the right end. The liquid that rushes into the collecting box 6 can enter the bottom of the box 1 through the reflux pipe 8 after being filtered by the microporous filter 801. When the operator holds and turns the handle 702, the valve block 701 can be driven to move in the discharge valve 7, so that the solid catalyst collected in the collecting box 6 can be discharged vertically downward. The liquid filtered and separated by the inclined sieve plate 3 and the microporous filter 801 can be discharged from the box 1 through the liquid outlet pipe 5.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
