Abstract

The utility model relates to a catalyst dryer with protection pins, mainly aiming at solving the problem that the service life of a graphite gasket is shortened because the sealing cover of the dryer in the prior art is frequently closed and lifted up. The catalyst dryer with protection pins is characterized in that lower ends of four to six protection pins (2) are evenly fixed on a side surface where the upper part of a dryer body (1) and a sealing cover (3) are hermetically butted and the upper ends of the protection pins (2) tilt outwards. The catalyst dryer with protection pins has the advantages that the placing times of the sealing cover can be reduced and the service life of the graphite gasket is prolonged.

Description

Install the catalyst drier of guard pins additional

Technical field

The utility model relates to a kind of catalyst drier in the petrochemical industry, particularly a kind of catalyst drier that installs guard pins additional.

Background technology

Petrochemical plant Catalyst Production unit is often used drier and is come dry catalyst.In the existing phosphoric acid catalyst production unit; In the process of silica gel filling, discharging and catalyst filling, discharging, need the frequent end socket that hangs on, hangs down on the drier with the sky to cover, the white steel Graphite pad of 1.3 meters of diameters is housed between end socket lid and the drier opening; Every of white steel Graphite pad is worth 800-1000 unit; When being placed in the lifting of end socket lid on the drier, each orientation all must align just and can lay successfully up and down at every turn, reaches good sealing effectiveness.Therefore need the repeatedly lifting could success, heavy 0.5 ton because end socket covers, frequent hangs on end socket, particularly moves horizontally the Graphite pad destructive power greatlyyer, directly shortens life-span of Graphite pad.

Summary of the invention

The utility model technical problem to be solved is to overcome frequent the covering, sling and the problem that shortens the service life of Graphite pad of the drier end socket lid that exists in the background technology; And a kind of catalyst drier that installs guard pins additional is provided; This installs the catalyst drier of guard pins additional; Can reduce the number of times of laying of end socket lid, prolong the service life of Graphite pad.

The utility model solves its problem and can reach through following technical scheme: this catalyst drier that installs guard pins additional comprises the drier body; Drier upper part of body opening part is equipped with the end socket lid; End socket covers the center suspension hook is housed; Be equipped with Graphite pad between drier upper part of body opening and end socket lid, the side of described drier body top and end socket lid Butt sealing evenly is fixed with the lower end of 4 to 6 guard pins, and the guard pins upper end is outward-dipping.

Described guard pins upper end is 30 degree with the inclination angle of drier body axis.

The utility model and above-mentioned background compared with techniques can have following beneficial effect: this installs the catalyst drier of guard pins additional owing to adopt said structure, and used end socket lid is slipped to the normotopia place along the gradient of guard pins, lays at every turn and all guarantees once success.Improve operator's labour intensity greatly, prolonged the service life of Graphite pad simultaneously.Graphite pad becomes a slice every two years by annual a slice, and the life-span doubles.This catalyst dryer configuration is simple, easy to operate.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model;

Accompanying drawing 2 is vertical views of drier body among Fig. 1.

Among the figure: 1-drier body, 2-guard pins, 3-end socket lid, 4-suspension hook, 5-Graphite pad.

The specific embodiment:

To be described further the utility model below in conjunction with accompanying drawing:

Accompanying drawing 1 combines shown in Figure 2; This catalyst drier that installs guard pins additional comprises drier body 1; The upper opening place of drier body 1 is equipped with end socket lid 3, and suspension hook 4 is equipped with in the center on the end socket lid 3, and the upper opening of

drier body

1 and 3 on end socket lid are equipped with Graphite pad 5; The side of described drier body 1 top and end socket lid Butt sealing evenly is welded with the lower end of 4 to 6 guard pins 2, and guard pins 2 upper ends are outward-dipping; The inclination angle of described guard pins 2 upper ends and drier body 1 axis is 30 degree.

The guard pins of welding on the drier body, each guard pins is processed by circular high strength cast iron, is welded on the side of drier body top and end socket lid Butt sealing uniformly.Guard pins length can not be long, and as long, then anti-crushing strength is not enough.Even end socket lid is laid inaccurately like this, slightly deflect away from, as long as in the scope of guard pins, can lay, the end socket lid is slipped to the normotopia place along the gradient of guard pins, lays all to guarantee once successfully at every turn.

Claims

1. catalyst drier that installs guard pins additional; Comprise drier body (1); The upper opening place of drier body (1) is equipped with end socket lid (3); End socket lid (3) is gone up the center suspension hook (4) is housed; Be equipped with Graphite pad (5) between the upper opening of drier body (1) and end socket lid (3), it is characterized in that: the side of described drier body (1) top and end socket lid (3) Butt sealing evenly is fixed with the lower end of 4 to 6 guard pins (2), and guard pins (2) upper end is outward-dipping.

2. the catalyst drier that installs guard pins additional according to claim 1 is characterized in that: described guard pins (2) upper end is 30 degree with the inclination angle of drier body (1) axis.
