Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of catalyst sampling devices, and particularly relates to a catalyst particle sampler. Background Art
[0002] A catalyst generally refers to a substance that increases the reaction rate without changing the total standard Gibbs free energy change of the reaction. It can also be expressed as a substance that can provide the chemical reaction rate in a chemical reaction without changing the chemical equilibrium, and whose own mass and chemical properties do not change before and after the chemical reaction. According to statistics, more than 90% of industrial processes use catalysts, such as chemical engineering, petrochemical, biochemical, environmental protection, etc. There are many types of catalysts. According to the state, they can be divided into liquid catalysts and solid catalysts. Among them, most solid catalysts are made into particles of different shapes. According to the phase state of the reaction system, they are divided into homogeneous catalysts and heterogeneous catalysts. Homogeneous catalysts include acids, bases, soluble transition metal compounds, and peroxide catalysts. In the fields of petroleum and chemical engineering, solid particle catalysts supported by molecular sieves, alumina, diatomite, etc. account for more than 80%. Most of these solid catalyst products are packaged and shipped out in barrels with a capacity of more than 50L or in big bags. Generally, sampling and analysis are required during the factory shipment and the user's receipt and acceptance to check the quality of the catalyst products.
[0003] The existing methods for sampling catalyst particles generally use the plug-in tube method and the tube rotary sampling method. Because the length of the plug-in tube is limited, it is often impossible to collect representative samples from deep layers, and the one-time sampling amount is small. The sampling process needs to be repeated many times, which is very troublesome. In addition, it is impossible to sample quantitatively. The tube rotary sampling method has the following defects: during the process of inserting it into the catalyst particle material, the sharp head of the sampler will cause damage to the catalyst particles, increasing the risk of catalyst pulverization. At the same time, because the powder and ash are carried out with the sampler, it is easy to cause environmental pollution. In addition, this method cannot perform quantitative sampling either. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a catalyst particle sampler, the length of the sampling cylinder can be adjusted telescopically to achieve uniform sampling of catalysts at different longitudinal depths, and while realizing one-time quantitative sampling, it can automatically filter and collect the powder and ash generated during sampling, which is environmentally friendly, easy to operate, and fast.

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the art to which the present utility model pertains.
[0027] The "first", "second" and similar terms used in the description and claims of the patent application of the present utility model do not denote any order, quantity or importance, but are only used to distinguish different components. Similarly, unless the context clearly indicates otherwise, the singular forms such as "a", "an" or "the" do not denote a limitation of quantity, but mean that there is at least one. The terms such as "comprising" or "including" mean that the elements or items appearing before "comprising" or "including" cover the features, wholes, steps, operations, elements and / or components listed after "comprising" or "including", and do not exclude the existence or addition of one or more other features, wholes, steps, operations, elements, components and / or their combinations. The terms such as "upper", "lower", "left" and "right" are only used to indicate relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.
[0028] Based on the problems that the existing catalyst particle sampler cannot collect representative catalyst samples in the deep layer due to the limitation of length, cannot quantitatively sample during sampling, the sharp head of the sampler is prone to cause damage to catalyst particles, and powder and ash are easily carried out during the sampling process, the embodiments of the present utility model provide a catalyst particle sampler.
[0029] As Figure 1 shown, the catalyst particle sampler of the embodiments of the present utility model includes a sampling sleeve 1, a feed tube 2, a sample collection system, a telescopic tube 3, and a fan system. The sampling sleeve 1 includes a connecting tube and a plurality of tooth claws. The plurality of tooth claws are arranged in a conical structure and connected to the front end of the connecting tube. Among them, the front end of the conical structure is wide and the rear end is narrow. In addition, in order to enable the sampling sleeve 1 to evenly suck the surrounding catalyst during sampling, the tooth claws can be arranged at equal intervals, that is, the distance between any two adjacent tooth claws is the same, so as to ensure that the catalyst on the periphery of the sampling sleeve 1 enters the connecting tube through the gaps between the tooth claws with the same probability. The rear end of the connecting tube is detachably connected to the front end of the feed tube 2.
[0030] The sampling sleeve 1 is connected to the front end of the feed cylinder 2 in a detachable connection manner, so that when the catalyst particle sampler is actually used, a sampling sleeve 1 with a suitable specification can be selected according to the diameter of different catalyst particles, especially a connecting cylinder with different inner diameters. In some embodiments of the present invention, the sampling sleeve 1 is made of 316L stainless steel, and the inner diameter of the connecting cylinder is 3 cm - 5 cm, which is applicable to cylindrical or star-shaped catalysts with a particle size of Φ3.5 mm - Φ10 mm.
[0031] The sample collection system includes a collection cylinder 4, a solid powder separation device 5 and a volume adjustment cylinder 6. The front end of the collection cylinder 4 is connected to the rear end of the feed cylinder 2. There is a discharge port (not shown in the figure) on the side wall of the collection cylinder 4, and a sampling bag (not shown in the figure) is detachably connected to the discharge port through a buckle, so that the sampling bag is fixedly hung outside the collection cylinder 4. The front end of the volume adjustment cylinder 6 is movably connected to the inside of the rear end of the collection cylinder 4, so that the volume adjustment cylinder 6 can move along the axial direction of the collection cylinder 4. The solid powder separation device 5 is detachably connected to the front end of the volume adjustment cylinder 6. In a preferred embodiment of the present invention, in order to minimize the dead angle inside the collection cylinder 4 and better control and adjust the volume of the collection cylinder 4, the collection cylinder 4 adopts a hollow cylindrical structure, and the volume of the collection cylinder 4 is adjustable between 20 mL and 500 mL. The specific adjustment method of the collection cylinder 4 is to push the volume adjustment cylinder 6 along the axial direction of the collection cylinder 4 towards its front end, and the volume of the collection cylinder 4 can be compressed; pull the volume adjustment cylinder 6 along the axial direction of the collection cylinder 4 towards its rear end, and the volume of the collection cylinder 4 can be enlarged. When the sampling is completed and calculating the sampling amount of the catalyst, the total amount of the catalyst sample should be the amount of the catalyst existing inside the feed cylinder 2 plus the amount of the catalyst existing inside the collection cylinder 4. Therefore, for the convenience of calculation, the feed cylinder 2 is set with a fixed volume, that is, its inner diameter and length remain unchanged. And in order to obtain a more accurate actual volume of the collection cylinder 4 and facilitate the adjustment of the volume of the collection cylinder 4, a volume scale can also be set on the outer side wall of the volume adjustment cylinder 6, and the accuracy of the volume scale is ±0.1 mL.
[0032] In some preferred embodiments of the present invention, the sample collection system further includes an automatic sealing device (not shown in the figure). After the sampling is completed, the discharge port is opened. After all the catalysts inside the sampler fall into the sampling bag, the sampling bag is sealed through the automatic sealing device, so as to realize automatic packing and sealing. Among them, the automatic sealing device can adopt an existing automatic sealing device for bag packaging sealing, and its specific structure and working principle will not be elaborated here.
[0033] In the embodiment of the present utility model, the solid-powder separation device 5 includes several layers of filter wire meshes. The several filter wire meshes are stacked at the front end of the capacity adjustment cylinder 6, and the diameter of each filter wire mesh is adapted to the inner diameter of the collection cylinder 4. The mesh size of the filter wire mesh is 0.1 mm - 5 mm. Different filter wire meshes with different mesh sizes can be replaced according to actual situations. For example, when it is necessary to filter the dust in the catalyst, a filter wire mesh with a smaller mesh size can be selected; when it is necessary to count the number of fragments of the catalyst sample, a filter wire mesh with a larger mesh size can be selected, so that when sampling, irregular catalysts such as fragments, decapped, and chipped in the catalyst sample can pass through, while the catalysts with a complete shape cannot pass through. In order to obtain a better filtering effect, a combination of different mesh sizes can be adopted, that is, from the front end of the collection cylinder 4 to the rear end of the collection cylinder 4, the first-layer filter wire mesh, the second-layer filter wire mesh... the last-layer filter wire mesh are arranged in sequence. From the first-layer filter wire mesh to the last-layer filter wire mesh, the mesh size of each layer of filter wire mesh decreases continuously, so as to intercept all the dust or irregular catalysts between the filter wire meshes. The specific working principle of the solid-powder separation device 5 is that under the negative pressure suction effect generated by the fan system, the catalyst is sucked into the feed cylinder 2 and the collection cylinder 4. The dust with extremely fine particle size therein is adsorbed on the filter wire mesh, or the irregular catalyst passes through the first-layer filter wire mesh under a larger negative pressure, and then cannot penetrate through the subsequent several layers of filter wire meshes due to the decrease of the mesh size of the subsequent filter wire meshes and is intercepted between two adjacent layers of filter wire meshes, while the catalysts with a complete shape and qualified size are all intercepted in front of the first-layer filter wire mesh.
[0034] The front end of the telescopic cylinder 3 is connected to the rear end of the capacity adjustment cylinder 6, wherein the length dimension of the telescopic cylinder 3 is adjustable between 10 cm and 100 cm to adapt to the sampling of catalysts with different barrel volumes or barrel depths. The fan system is arranged at the rear end of the telescopic cylinder 3.
[0035] In the embodiment of the present utility model, the fan system includes a negative pressure fan 7 and a control handle 8. The air inlet end of the negative pressure fan 7 is connected to the rear end of the telescopic cylinder 3, the control handle 8 is connected to the air outlet end of the negative pressure fan 7, and several control buttons are arranged on the control handle 8. The control buttons are electrically connected to the negative pressure fan 7. Among them, the negative pressure fan 7 adopts a modular design and is assembled in a combined manner, and is equipped with a small solid-state lithium battery as the power supply. Its volume is small and easy to carry, and the charging is convenient and durable. It can be used about 200 times after being fully charged once. In some preferred embodiments, the negative pressure fan 7 is a variable-frequency negative pressure fan, and the frequency is adjustable between -5 KPa and -30 KPa. The larger the frequency, the greater the negative pressure generated when the negative pressure fan 7 works and rotates, and the greater the suction effect on the catalyst.
[0036] In some specific embodiments of the present utility model, there are 4 control buttons on the control handle 8, including the main button, the "+" button, the "-" button, and the "generate" button. Among them, the depth of a single press of the main button determines the magnitude of the suction force. When the main button is continuously pressed twice, the automatic sampling mode is activated according to the suction force during the previous sampling, and the sampling ends after release. Each press of the "+" button increases the suction force by 5 KPa; conversely, each press of the "-" button decreases the suction force by 5 KPa. After the sampling ends, the "generate" button is pressed to obtain the sampling information.
[0037] In some preferred embodiments of the present utility model, a data acquisition recorder 9 is further provided on the control handle 8, and the data acquisition recorder 9 is electrically connected to the negative pressure fan 7. The data acquisition recorder 9 uses an LED screen as the display device, with a screen diameter of 500 mm, having the function of automatically recording information such as the number of sampling times and sampling time, and being able to display the negative pressure value of the negative pressure fan in real time. The data result information of the sampling can be exported through data transmission methods such as Bluetooth, WIFI, or data cable. In addition, the data acquisition recorder can also adopt existing conventional technologies.
[0038] The main body of the sampler device in the embodiments of the present utility model, such as the feeding cylinder 2, the collection cylinder 4, the telescopic cylinder 3, etc., is made of high-density polyethylene (HDPE) material, making it high in strength, wear-resistant, lightweight, and strong in corrosion resistance.
[0039] The specific working process of the embodiments of the present utility model is as follows:
[0040] Open the buckle at the feed inlet, fix the bag mouth of the sampling bag at the feed inlet, select a suitable sampling sleeve 1, check whether the solid-state lithium battery of the negative pressure fan 7 is powered, check whether the mesh size of the solid powder separation device is appropriate, adjust the volume of the collection cylinder 4 to the required sampling volume. After the preparatory work is done, open the lid and the inner lining bag of the catalyst sealed barrel, insert the sampling sleeve 1 of the sampler into the surface layer of the catalyst, gently press the main button on the control handle 8, and the negative pressure fan 7 starts to rotate, making a micro-negative pressure form inside the sampler. At the same time, the current negative pressure value is displayed on the data acquisition recorder 9. As the pressing force of the main button increases, the negative pressure inside the sampler gradually rises. When the catalyst particles start to be sucked into the sampler, keep the pressing force of the main button unchanged, and use the hollow state formed instantaneously after the catalyst particles below the sampling sleeve 1 are sucked away to gradually insert the sampling sleeve 1 into the deep layer of the catalyst. When the length is insufficient, stretch the telescopic cylinder 3 to achieve uniform sampling in the longitudinal depth. When the catalyst fills the feed cylinder 2 and the collection cylinder 4 inside the sampler, release the main button, pull out the sampling sleeve 1, then open the discharge port to make all the catalyst samples fall into the sampling bag. After that, start the automatic sealing device to automatically seal and pack the sampling bag, then loosen the buckle and remove the sampling bag containing the catalyst sample. Finally, press the "Generate" button to obtain the sampling information of this sampling, including parameters such as sampling time, sampling times, sampling volume, and negative pressure value.
[0041] In actual sampling, single-batch multiple sampling and multi-batch multiple sampling methods are often adopted. For these sampling situations, after sampling a sample once, replace it with a new sampling bag. Similarly, insert the sampling sleeve 1 from the surface layer of the catalyst, then continuously press the main button twice, and use the negative pressure memory function of the control handle 8 to gradually insert the sampling sleeve 1 deep into the catalyst to achieve uniform sampling in the longitudinal depth. When all the sample samplings are completed, turn on the data transmission mode such as Bluetooth and export the sampling information to a mobile device in the form of an EXCEL file.
[0042] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Those with ordinary knowledge in the technical field to which the present utility model belongs can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to what is defined by the claims.
