Description

Technical Field

[0001] This utility model relates to the field of chemical machinery technology, specifically to an online block separator. Background Technology

[0002] In the field of synthetic resin particle conveying, pneumatic positive pressure conveying is currently the main method, especially in dilute phase conveying, where gas and particles are uniformly dispersed within the pipeline. Due to the high flow rate, flanges, welds, and other protrusions and edges in the pipeline cause particles to collide at high speed with these locations, generating a large amount of heat. This leads to the softening and adhesion of the material, forming lumps. The formation of these lumps has many adverse effects on subsequent conveying, metering, and processing.

[0003] From the perspective of current technology, although there are facilities on the market for capturing large pieces of material, they have obvious drawbacks. Some facilities have small buffer spaces, requiring frequent cleaning, which can easily cause pipeline blockages and even system shutdowns. Other facilities have screens with large gaps, making it impossible to effectively separate smaller pieces of material, thus causing downstream equipment to jam. Furthermore, the process of cleaning up large pieces of material also leads to a significant loss of product.

[0004] In summary, there is currently a lack of suitable and effective online de-lumping equipment and facilities in the industry and market. This invention employs a slotted filter screen and, through a special structural design, rationally selects the screen gap and adjusts the equipment size according to the particle conveying capacity. The aim is to achieve online removal of lumpy materials on the conveying pipeline, and there are currently no relevant documents or reports on this de-lumping method. Utility Model Content

[0005] This utility model provides an online block material separator, which aims to solve the problem of ineffective separation and removal of block materials generated in pneumatic conveying pipelines, and to solve the problems of unstable system operation and high failure rate, thereby improving the system's operational stability.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An online block separator includes a square vertical body, which is installed on a vertical pipe and close to the end of the air conveying pipeline; the body is provided with an inclined slotted grid and a block collection area in the middle, and the conveyed particles enter from the top of the body and exit from the bottom.

[0008] Furthermore, the grid is made of stainless steel metal strips with a width of 0.5-0.8cm and a gap of 1cm. The grid is tilted at an angle of 20°, and the separated blocks can automatically slide into the block collection area.

[0009] Furthermore, the block material collection area is provided with two layers of partitions, including a vertical partition and a horizontal partition; the vertical partition is used to prevent the conveyed particles and gas from escaping outwards, and the horizontal partition is used to prevent external impurities from entering the conveying system.

[0010] Furthermore, the bottom plate of the block material collection area is tilted at a 45° angle toward the separator so that the particles carried out during the cleaning of the block material can automatically slide into the lower layer of the separator.

[0011] The beneficial effects achieved by this utility model are as follows:

[0012] This utility model discloses an online block separator. As an online block separation device, it can effectively separate and remove lumps of resin particles during pneumatic conveying. It is simple to operate and has significant effects. It avoids the need to stop the pneumatic conveying line to clean up lumps, reducing particle loss and thus improving the stability of the device's operation. When cleaning lumps from the separator, no particles remain, reducing product loss and achieving complete separation of lumps and particles. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, if the word "and / or" appears throughout the text, it means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] This solution uses a slotted filter screen with a special structural design. By selecting an appropriate screen gap and adjusting the equipment size according to the particle conveying capacity, it achieves the purpose of removing lumps online on the conveying pipeline. Currently, there is no relevant literature or report on this lumping removal method.

[0024] like Figure 1 and Figure 2 As shown, this utility model provides an online block separator 7. The online block separator 7 adopts a square, vertical design, with a length and width of 60cm and a height of 90cm. It is installed on a vertical pipe, near the end of the pneumatic conveying pipeline. The conveyed particles enter from the upper inlet 4 and exit from the lower outlet 5. An inclined slotted grid 1 and a block collection area 6 are set in the middle of the separator.

[0025] The grating 1 is made of stainless steel strips, with a strip width of 0.5-0.8cm and a gap of 1cm between the strips. The grating is tilted at a 20° angle, and the separated blocks automatically slide into the collection area.

[0026] The block material collection area 6 is equipped with two layers of partitions. The vertical partition 2 prevents the conveyed particles and gas from escaping outwards; the horizontal partition 3 prevents external impurities, rainwater, etc. from entering the conveying system. The bottom plate of the collection area is inclined at a 45° angle towards the separator, so that the particles brought out during the cleaning of block materials can automatically slide into the lower layer of the separator.

[0027] This solution, as an online block separation device, effectively achieves the online separation and removal of lumps of resin particles during pneumatic conveying. It is simple to operate and yields significant results. It avoids the need to stop the pneumatic conveying line to clean up lumps, reduces particle loss, and thus improves the operational stability of the device.

[0028] The practical effects of applying this technology to ABS devices are as follows:

[0029] 1. When cleaning the block material from the separator, there is no longer any granular material, reducing product loss and achieving complete separation of block and granular materials.

[0030] 2. The particles filtered by the online block separator 7 contain no more than 1cm of block material of the largest size. When they enter the rotary valve and screw conveyor of the next process, the tooth spacing and screw pitch are 5-10cm, which does not affect the normal operation of the particle conveying equipment.

[0031] 3. After the online block separator 7 designed using this invention has been running for several months, the pneumatic conveying system has not experienced any abnormal shutdowns due to the cleaning of block materials.

[0033] Before improvement 2-4 hours 10 Improved More than 8 hours 2.5

[0034] This solution has been implemented on an ABS unit, covering a total of 12 silos. Twelve block separators have been manufactured, achieving online separation of blocks with excellent results. This reduces material loss during cleaning and completely solves the problem of abnormal downtime caused by blocks. Installation locations are as follows... Figure 3 As shown.

[0035] During use, the lumps in the separator are cleaned once per shift. Each operation can be completed within 3 minutes, and the cleaned lumps no longer contain any granular material.

[0036] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
