Description

Technical Field

[0001] This utility model relates to the technical field of desulfurizing agent production equipment, specifically to a production mold for calcium-based desulfurizing agent. Background Technology

[0002] Calcium-based desulfurizers are chemical agents used for desulfurization and are widely used in coal-fired power plants and the petrochemical industry. They can effectively remove sulfur dioxide from flue gas, improve flue gas quality, and treat sulfur-containing waste gas, protecting the environment and human health. Molds are required when producing desulfurizers.

[0003] Existing molds used for desulfurizer production experience greater pressure in the center and less pressure around the edges when subjected to extrusion pressing, resulting in greater mold wear and affecting the mold's service life. Utility Model Content

[0004] The purpose of this invention is to provide a production mold for calcium-based desulfurizer, which solves the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0006] A production mold for a calcium-based desulfurizer includes a circular mold body with a plurality of mold holes symmetrically arranged on the circular mold body. Each mold hole is in the shape of a four-leaf clover with different leaf sizes, and the four-leaf clover-shaped mold hole is symmetrical about the cross section of the circular mold body passing through the central axis.

[0007] In a preferred embodiment of this utility model, the number of mold holes is 5.

[0008] In a preferred embodiment of this utility model, the mold hole includes two first arc-shaped holes and two second arc-shaped holes. The radius of the first arc-shaped holes is larger than the radius of the second arc-shaped holes. Both the two first arc-shaped holes and the two second arc-shaped holes are symmetrical about a cross section on the circular mold body. This cross section passes through the central axis of the circular mold body. The two first arc-shaped holes are connected, and the connection point of the two first arc-shaped holes is transitioned through an arc surface. The two second arc-shaped holes are connected, and each first arc-shaped hole is connected to a corresponding second arc-shaped hole.

[0009] As a preferred embodiment of this utility model, the diameter of the circular mold body is 18.95mm and the thickness is 6.00mm.

[0010] As a preferred embodiment of this utility model, the diameter of the first arc-shaped hole is 2.40 mm, the diameter of the second arc-shaped hole is 2.10 mm, and the diameter of the arc surface at the connection of the two first arc-shaped holes is 0.72 mm.

[0011] Using the symmetrical plane of the two first arc-shaped holes as the first reference plane, and the plane on the circular mold body perpendicular to the first reference plane as the second reference plane, and the second reference plane passing through the central axis on the circular mold body, the distance between the center of the first arc-shaped hole and the first reference plane is 1.39 mm, the distance between the center of the second arc-shaped hole and the first reference plane is 0.975 mm, the distance between the first arc-shaped hole and the second reference plane is 3.51 mm, the distance between the second arc-shaped hole and the second reference plane is 4.41 mm, the distance between the center of the arc surface and the first reference plane is 0, and the distance between the center of the arc surface and the second reference plane is 7.0659 mm.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] In this invention, the surface area of ​​the product manufactured by the clover-shaped mold hole is larger than that of the product manufactured by the existing mold of the same size, thereby improving the reaction effect of the product with sulfur dioxide in the flue gas. In addition, the first arc-shaped hole and the second arc-shaped hole have different sizes. Compared with the clover-shaped mold hole of the same size, the mold hole in this invention is subjected to more balanced pressure, which reduces the wear and tear of the mold during use and extends its service life.

[0015] To more clearly illustrate the embodiments of this utility model or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings in the following description are merely exemplary, and those skilled in the art can derive other embodiments based on the provided drawings without creative effort.

[0019] 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.

[0020] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, this utility model provides a production mold for a calcium-based desulfurizer, including a circular mold body 1. Multiple mold holes 2 are symmetrically arranged on the circular mold body 1. Each mold hole 2 is in the shape of a four-leaf clover with different leaf sizes, and the four-leaf clover-shaped mold hole 2 is symmetrical about the cross section of the circular mold body 1.

[0022] The number of mold holes 2 is 5.

[0023] The mold hole 2 includes two first arc-shaped holes 201 and two second arc-shaped holes 202. The radius of the first arc-shaped holes 201 is larger than the radius of the second arc-shaped holes 202. Both the two first arc-shaped holes 201 and the two second arc-shaped holes 202 are symmetrical about the cross section on the circular mold body 1. This cross section passes through the central axis on the circular mold body 1. The two first arc-shaped holes 201 are connected, and the connection point of the two first arc-shaped holes 201 is transitioned through an arc surface. The two second arc-shaped holes 202 are connected, and each first arc-shaped hole 201 is connected to the corresponding second arc-shaped hole 202.

[0024] In practical use, the mold hole 2 is used to fill the raw material and manufacture products of the corresponding shape (i.e., calcium-based desulfurizer). Since the diameters of the first arc-shaped hole 201 and the second arc-shaped hole 202 forming the mold hole 2 in this application are different, and the diameter of the first arc-shaped hole 201 is larger than the diameter of the second arc-shaped hole 202, compared with the existing molds which are subjected to greater pressure in the middle and smaller pressure around the edges when pressed by the extruder, the clover-shaped mold hole 2 of this application can effectively balance the pressure, reduce the wear of the entire mold, extend the service life of the entire mold, and the surface area of ​​the product produced by this application is larger than that of the product produced by the existing molds, which effectively improves the reaction effect of the product with sulfur dioxide in the flue gas, thereby improving the desulfurization effect.

[0025] The diameter of the circular mold body 1 is 18.95mm and the thickness is 6.00mm.

[0026] The diameter of the first arc-shaped hole 201 is 2.40 mm, the diameter of the second arc-shaped hole 202 is 2.10 mm, and the diameter of the arc surface at the connection of the two first arc-shaped holes 201 is 0.72 mm.

[0027] Using the symmetrical plane of the two first arc-shaped holes 201 as the first reference plane, and the plane on the circular mold body 1 perpendicular to the first reference plane as the second reference plane, and the second reference plane passes through the central axis on the circular mold body 1, the distance between the center of the first arc-shaped hole 201 and the first reference plane is 1.39 mm, the distance between the center of the second arc-shaped hole 202 and the first reference plane is 0.975 mm, the distance between the first arc-shaped hole 201 and the second reference plane is 3.51 mm, the distance between the second arc-shaped hole 202 and the second reference plane is 4.41 mm, the distance between the center of the arc surface and the first reference plane is 0, and the distance between the center of the arc surface and the second reference plane is 7.0659 mm.

[0028] The arc length of the first arc-shaped hole 201 projected onto the surface of the circular mold body 1 is 4.0821 rad, the arc length of the second arc-shaped hole 202 projected onto the surface of the circular mold body 1 is 3.8016 rad, and the arc length of the arc surface projected onto the surface of the circular mold body 1 is 2.8696 rad.

[0029] Since the mainstream four-leaf clover-shaped desulfurizer products on the market are between 4.7mm and 5.6mm, the products produced by this mold can better meet market requirements. Furthermore, the maximum diameter of the existing mold is about 5.4mm. Since the size of the mold hole of the existing extrusion machine is fixed, opening five mold holes 2 on the circular mold body 1 can make better use of space.

[0030] Experimental Example

[0031] The experiment used sulfur dioxide as a standard gas with a sulfur dioxide content of 200–250 mg / m³, and employed an SUV-100 flue gas analyzer from Shandong Xinze Instrument Co., Ltd. The experiment used a clover-shaped product produced from a 5.40 mm circular mold body 1 manufactured according to this invention as an example, and a product made from the same raw materials and a 5.56 mm cylindrical mold of the same material specifications as a comparative example to compare the desulfurization effects.

[0032] Table 1. Desulfurization effect tests of the examples and comparative examples.

[0033] — Maximum diameter of product Mass (g) Number of experiments Average desulfurization time Example 5.53mm 100 5 17min33s Comparative Example 5.64mm 100 5 11min29s

[0034] Results and Analysis: According to the data in Table 1, the average desulfurization time of the product made using this application in the embodiment is greater than that of the product in the comparative example, which significantly shows that the product made using the clover-shaped mold hole 2 in this application has a better desulfurization effect.
