Description

Technical Field

[0001] This utility model relates to the field of pulping enzyme production technology, specifically a multi-stage separation and purification device for pulping enzyme production. Background Technology

[0002] Pulping enzyme is a complex bioenzyme, its main component being endoglucanase. It degrades cellulose in the fiber cell wall, aiding in cell wall separation and promoting fiber fibrillation. By disrupting the outer layers of the primary and secondary fiber walls, it promotes fibrillation of the inner secondary wall and fiber swelling. Simultaneously, it modifies the fiber surface, increasing hydroxyl and carboxyl groups on the fiber surface and at the ends, thereby altering fiber morphology, making it easier to pulp, reducing energy consumption, and improving paper strength. Pulping enzyme production refers to the production of a complex bioenzyme specifically for the pulping process in the papermaking industry. Pulping enzymes are widely used in the papermaking industry, especially in the production of high-grade tissue paper, copy paper, and specialty paper made from long-fiber softwood bleached pulp. Using pulping enzymes can save refining energy consumption, reduce production costs, and improve the tensile, tear, and burst strength of the finished paper. To improve the production efficiency of pulping enzymes, a separation and purification device is needed; however, existing separation and purification devices still have the following shortcomings:

[0003] When using existing separation and purification devices, it is not convenient to quickly and securely install multiple filters inside the device. This makes the installation and removal of filters time-consuming and labor-intensive, which increases the manual labor intensity of subsequent filter maintenance. Consequently, the normal use of the separation and purification device is affected, resulting in a decrease in the practicality and efficiency of the device. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage separation and purification device for pulping enzyme production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage separation and purification device for pulping enzyme production, comprising a main body and an installation assembly. The main body has supporting columns installed at its bottom and an installation top cover at its upper end. A feed pipe is located on the left side of the upper end of the installation top cover. The installation assembly is located outside the main body and includes a limiting cylinder, a limiting rod, a return spring, a first filter screen, a limiting through hole, a second filter screen, and a third filter screen. The limiting cylinder is connected to the limiting rod, and a return spring is located inside the limiting cylinder outside the limiting rod. The main body has a first filter screen inside, with a limiting through hole on its inner outer side. A second filter screen is located below the first filter screen, and a third filter screen is located below the second filter screen. A cleaning assembly is located inside the main body.

[0006] Furthermore, the limiting rod and the limiting cylinder are embedded in each other, and the limiting rod is elastically connected to the limiting cylinder through a return spring.

[0007] Furthermore, the external dimensions of the limiting rod are adapted to the internal dimensions of the limiting through hole, and the limiting rod is connected to the first filter screen through the limiting through hole.

[0008] Furthermore, the external dimensions of the first filter screen are adapted to the internal dimensions of the main body, and the outer side of the first filter screen is tightly fitted to the inner wall of the main body.

[0009] Furthermore, the cleaning assembly includes a servo motor, a support rod, and an upper cleaning brush. The front end of the servo motor is connected to the support rod, and the upper cleaning brush is installed on the outside of the support rod.

[0010] Furthermore, the cleaning assembly also includes a lower cleaning brush, a mounting crossbar, and a scraper, with the lower cleaning brush located below the upper cleaning brush. The mounting crossbar is located on the outer side of the lower end of the support rod, and a scraper is installed at the front end of the mounting crossbar.

[0011] Furthermore, the number of upper cleaning brushes is set to nine, with three upper cleaning brushes forming a group, and each group of upper cleaning brushes being equidistantly distributed on the outside of the support rod.

[0012] Furthermore, the mounting crossbar is perpendicular to the scraper plate, and the mounting crossbar and the scraper plate are fixedly connected by bolts.

[0013] This invention provides a multi-stage separation and purification device for pulping enzyme production, which has the following advantages:

[0014] 1. This utility model, through the setting of the installation components, enables the multi-stage separation and purification device for pulping enzyme production to be used. The limit rod and the limit cylinder are elastically connected by the return spring, and the first filter screen is installed inside the main body.

[0015] 2. By setting up a cleaning component, this utility model enables the multi-stage separation and purification device for pulping enzyme production to be used. The servo motor drives the support rod to rotate, causing the upper and lower cleaning brushes connected to the outside of the support rod to rotate accordingly. The three sets of upper cleaning brushes, in conjunction with the lower cleaning brushes, clean the upper and lower surfaces of the filter screen. At the same time, the crossbar, along with the rotation of the support rod, drives the scraper plate to rotate at the lower end of the main body, thereby scraping the separated and purified pulping enzyme on the inner wall of the main body, avoiding material residue and waste, and improving the overall practicality and efficiency of the separation and purification device.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2As shown, a multi-stage separation and purification device for pulping enzyme production includes a main body 1 and an installation assembly 5. Support legs 2 are installed at the bottom of the main body 1, and an installation top cover 3 is provided at the upper end of the main body 1.

The installation assembly 5 is located outside the main body 1 and includes a limiting cylinder 501, a limiting rod 502, a reset spring 503, a first filter screen 504, a limiting through hole 505, a second filter screen 506, and a third filter screen 507. The limiting rod 502 is connected inside the limiting cylinder 501. Furthermore, a return spring 503 is provided inside the outer limiting cylinder 501 of the limiting rod 502. A first filter screen 504 is provided inside the main body 1, and a limiting through hole 505 is opened on the outer side of the inner side of the first filter screen 504. A second filter screen 506 is provided below the first filter screen 504, and a third filter screen 507 is provided below the second filter screen 506. The limiting rod 502 and the limiting cylinder 501 are embeddedly connected, and the limiting rod 502 is elastically connected to the limiting cylinder 501 through the return spring 503. The outer dimensions of the limiting rod 502 and the limiting through hole 505 are consistent. The internal dimensions of the first filter 504 are compatible, and the limiting rod 502 is connected to the first filter 504 through the limiting through hole 505. The external dimensions of the first filter 504 are compatible with the internal dimensions of the main body 1, and the outer side of the first filter 504 is tightly fitted to the inner wall of the main body 1. The limiting cylinder 501 is fixedly installed on the outside of the main body 1 by fastening bolts. The limiting rod 502 is installed inside the limiting cylinder 501, and the limiting rod 502 is elastically connected to the limiting cylinder 501 by the return spring 503. At the same time, the first filter 504 is installed inside the main body 1. The internal dimensions of the limiting through-hole 505 on the inner and outer sides of the first filter screen 504 are adapted to the external dimensions of the limiting rod 502. Thus, the first filter screen 504 is limited and installed inside the main body 1 by the limiting rod 502 in conjunction with the limiting through-hole 505. Similarly, the second filter screen 506 and the third filter screen 507 are limited and installed inside the main body 1. The first filter screen 504, the second filter screen 506 and the third filter screen 507 are used to perform multi-stage separation and purification of the pulping enzyme, thereby improving the overall practicality and efficiency of the separation and purification device.

[0022] like Figures 1 to 3As shown, the main body 1 is equipped with a cleaning component 6. The cleaning component 6 includes a servo motor 601, a support rod 602, and an upper cleaning brush 603. The front end of the servo motor 601 is connected to the support rod 602, and the upper cleaning brush 603 is installed on the outside of the support rod 602. The cleaning component 6 also includes a lower cleaning brush 604, a mounting crossbar 605, and a scraper 606. The lower cleaning brush 604 is located below the upper cleaning brush 603. The mounting crossbar 605 is located on the outer side of the lower end of the support rod 602, and the scraper 606 is installed at the front end of the mounting crossbar 605. There are nine upper cleaning brushes 603, with three upper cleaning brushes 603 forming a group. Each group of upper cleaning brushes 603 is equidistantly distributed on the outside of the support rod 602. The mounting crossbar 605 and the scraper 606 are perpendicular to each other, and the mounting crossbar 605 and the scraper 606 are fixedly connected by bolts. The servo motor 601 is fixedly mounted on the upper middle part of the mounting top cover 3 with bolts. The output shaft of the servo motor 601 is connected to the support rod 602 through a coupling. The operation of the servo motor 601 drives the support rod 602 to rotate, causing the upper cleaning brush 603 and lower cleaning brush 604 connected to the outside of the support rod 602 to rotate accordingly. The three sets of upper cleaning brushes 603 and lower cleaning brushes 604 are used to clean the upper and lower surfaces of the filter screen. At the same time, the mounting crossbar 605 is fixedly mounted on the lower end of the support rod 602. The scraper 606 is fixedly mounted on the front end of the mounting crossbar 605 with fastening bolts. The mounting crossbar 605 rotates with the support rod 602, causing the scraper 606 to rotate inside the lower end of the main body 1, thereby scraping the purified pulping enzyme separated on the inner wall of the main body 1, avoiding material residue and waste, and improving the overall practicality and efficiency of the separation and purification device.

[0023] In summary, this multi-stage separation and purification device for pulping enzyme production, during use, firstly, enhances the stability of the equipment during operation by using the support column legs 2 installed at the bottom of the main body 1. The mounting top cover 3 is then fixedly installed on the upper part of the main body 1 to increase the overall sealing of the main body 1. The pulping enzyme to be processed is fed into the main body 1 through the feed pipe 4. The limiting rod 502 and the limiting cylinder 501 are elastically connected by the return spring 503. Simultaneously, the first filter screen 504 is installed inside the main body 1, and the first filter screen 504 is limited and installed inside the main body 1 by the limiting rod 502 and the limiting through hole 505. Similarly, the second filter screen 506 and the third filter screen 507 are limited and installed inside the main body. Inside the main body 1, the first filter screen 504, in conjunction with the second filter screen 506 and the third filter screen 507, performs multi-stage separation and purification of the pulping enzyme. Then, the servo motor 601 drives the support rod 602 to rotate, causing the upper cleaning brush 603 and the lower cleaning brush 604 connected to the outside of the support rod 602 to rotate as well. The three sets of upper cleaning brushes 603 and lower cleaning brushes 604 clean the upper and lower surfaces of the filter screens. At the same time, the crossbar 605 rotates with the support rod 602, causing the scraper 606 to rotate at the lower end of the main body 1, thereby scraping the separated and purified pulping enzyme on the inner wall of the main body 1, avoiding material residue and waste, and improving the overall practicality and efficiency of the separation and purification device.
