Petrochemical industry, also known as petrochemical industry, refers to the field of chemical industry that uses petroleum as raw materials to produce chemicals. Broadly speaking, it also includes natural gas chemical industry. The varieties of chemicals produced from petroleum and natural gas are extremely numerous and wide-ranging. When processing petrochemical raw materials, it is generally necessary to pretreat the raw materials.

[0003] A Chinese patent discloses a chemical raw material pretreatment device (authorization announcement number CN218741444U). The filter mesh plate set in it can facilitate the filtration treatment of raw materials during use, can remove impurities in the raw materials, and the raw materials of the required specifications can be obtained through filtration, which is convenient for pretreating the raw materials. The specification of the filter mesh plate can be replaced according to needs during use. However, the above only filters the raw materials through a single filter mesh plate. Since the size of the mesh holes on the filter mesh plate is fixed, it cannot filter out finer impurities in the raw materials. Therefore, the fine impurities easily seep out through the mesh holes on the filter mesh plate, and the filtration accuracy needs to be improved. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3 , the present utility model provides an efficient petrochemical raw material pretreatment device, including a treatment tank 1. Four corners at the bottom of the treatment tank 1 are vertically fixedly connected with support legs 11, and a discharge port 12 is fixedly communicated with the center of the bottom of the treatment tank 1. A filter screen 13 is fixedly connected inside the treatment tank 1, and a sponge 14 is installed on the top of the filter screen 13. A first vertical rod 2 and a second vertical rod 3 are respectively fixedly connected to both sides of the treatment tank 1. Guide grooves 4 are longitudinally penetrated inside the first vertical rod 2 and the second vertical rod 3, and a cross bar 5 is fixedly connected between the first vertical rod 2 and the second vertical rod 3.

[0020] A pressing mechanism 6 is installed on the cross bar 5. The pressing mechanism 6 includes a servo motor 61, a first threaded rod 62 and a second threaded rod 63. The driving end of the servo motor 61 penetrates through the cross bar 5 and is fixedly installed with the first threaded rod 62. An external fixed sleeve of the first threaded rod 62 is provided with a first pulley 621, and a first adjusting rod 622 is threadedly sleeved at the bottom of the first threaded rod 62. A second threaded rod 63 is installed on one side of the first threaded rod 62. An external fixed sleeve of the second threaded rod 63 is provided with a second pulley 631, and a second adjusting rod 632 is threadedly sleeved at the bottom of the second threaded rod 63. A transmission belt 64 is connected between the first pulley 621 and the second pulley 631. Guide rods 65 are fixedly connected to both the first adjusting rod 622 and the second adjusting rod 632, and a pressing plate 66 is fixedly connected to the bottom ends of the first adjusting rod 622 and the second adjusting rod 632. The length of the pressing plate 66 is less than the length of the filter screen 13, and the width of the pressing plate 66 is less than the width of the filter screen 13. The pressing plate 66 is slidably connected inside the processing box 1. The top end of the second threaded rod 63 is rotatably connected to the bottom of the cross bar 5 through a bearing. The servo motor 61 is fixedly connected to the top of the cross bar 5. The thread direction of the first threaded rod 62 is the same as that of the second threaded rod 63, and the length of the first threaded rod 62 is equal to the length of the second threaded rod 63. The first adjusting rod 622 and the second adjusting rod 632 are parallel to each other, and both the first adjusting rod 622 and the second adjusting rod 632 are vertically distributed. The guide rod 65 is of a "Z" structure, and the guide rod 65 is slidably connected inside the guide groove 4. By means of the downward pressure of the pressing mechanism 6, the pressing plate 66 can be driven to continuously move downward, so that the petrochemical raw materials adsorbed in the sponge 14 can be squeezed. Compared with the traditional single filtering method, finer impurities in the petrochemical raw materials can be filtered out, the filtering accuracy of the petrochemical raw materials can be improved, and the filtering efficiency is significantly improved by means of mechanical transmission to press and filter the petrochemical raw materials.

[0021] Among them, the model of the servo motor 61 is ACSM110 - G04030LZ.

[0022] Working principle: When using this device, pour petrochemical raw materials into the top of the treatment tank 1. At this time, the petrochemical raw materials can penetrate into the sponge 14. Then, control the servo motor 61 to rotate forward. At this time, the first threaded rod 62 can be driven to rotate forward. Since the first threaded rod 62 and the second threaded rod 63 are connected by the first pulley 621, the transmission belt 64 and the second pulley 631, the second threaded rod 63 can be driven to rotate forward synchronously. Utilizing the limiting effect of the guide rod 65 in the guide groove 4, the first adjusting rod 622, the second adjusting rod 632 and the pressing plate 66 can be driven to move downward continuously. When the pressing plate 66 moves into the treatment tank 1, the sponge 14 can be squeezed. At this time, the impurities in the petrochemical raw materials stay in the sponge 14, while the oil seeps downward through the filter screen 13 and is finally discharged through the discharge port 12. When the sponge 14 is blocked, it can be taken out of the treatment tank 1 and replaced with a new one.
