Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbide raw material calibration, in particular to a device for accurately calibrating calcium carbide raw materials. Background Art

[0002] Calcium carbide is usually produced by reacting coke with calcium oxide. During the reaction process, the raw materials usually need to be weighed in order to accurately control the ratio of the reaction raw materials.

[0003] Most of the existing weighing methods are to discharge materials from the hopper and store them in the storage frame, and then use a conveying device to slide the materials stored in the storage frame through a roller to the weighing device for weighing. This weighing method has strict requirements on the storage frame. When storage frames of different sizes slide onto the weighing device, they are prone to unstable center of gravity and fall, resulting in weighing failure or inaccurate weighing; at the same time, in the existing weighing device, the baffle on the right is rigid and easy to contact with the storage frame, resulting in inaccurate weighing.

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement.

[0025] See also Figures 1 to 4 The present invention provides a device for accurately weighing calcium carbide raw materials, comprising an obliquely arranged feeding and calibration assembly 10, the feeding and calibration assembly 10 comprising a base frame 101 and a roller 102 mounted on the base frame 101; a calibration frame 104 is symmetrically provided on the roller 102, and the calibration frame 104 is mounted on the base frame 101 by a bidirectional threaded rod 103, which can be centrally clamped and loosened;

[0026] A weighing assembly 20 is provided on the right side of the correction frame 104 . The weighing assembly 20 includes a weighing device 202 . An elastic plate 203 is provided on the right side of the weighing device 202 . The elastic plate 203 is elastically connected to a mounting plate 205 via a spring 204 . The mounting plate 205 is mounted on the table 201 .

[0027] How it works

[0028] When in use, the switch of the conveying device is turned on, and the calcium carbide raw materials can be conveyed to the roller. The calcium carbide raw materials loaded in the storage frame will be rolled onto the weighing device through the obliquely set roller and automatically weighed. If the weighing is qualified, it will be pushed to the discharging device by manpower. If it is unqualified, the feeding device will be stopped and the material will be added or reduced until it is qualified.

[0029] The set correction frame can be adjusted according to the size of the storage frame, so that the storage frame can be automatically corrected and accurately rolled onto the weighing machine;

[0030] The elastic plate can be set to bounce the storage frame to avoid the storage frame and the elastic plate from contacting and causing inaccurate weighing.

[0031] In some embodiments, see Figure 1 As shown, the symmetrically arranged calibration frame 104 is in a V-shape with an opening on the right side, and the weighing device 202 is arranged below the V-shaped opening of the calibration frame 104 .

[0032] This arrangement allows the material storage frame to slide onto the weighing device during weighing. The material storage frame is a frame for storing calcium carbide raw materials and is not the subject of protection of this solution.

[0033] In some embodiments, see Figure 3 As shown, the mounting plate 205 is movably mounted on a U-shaped frame 206 , the U-shaped frame 206 is movably mounted on a bracket 207 , and the bracket 207 is mounted on the table 201 by bolts.

[0034] This makes it easy to adjust the height of the elastic plate and the distance between the elastic plate and the weighing device, ensuring that the elastic plate fits the material storage frame and that the material storage frame can accurately fall on the weighing device.

[0035] In some embodiments, see Figure 1 and 4 As shown, the base frame 101 is provided with auxiliary shafts 105 on both sides of the bidirectional threaded rod 103 , and the correction frame 104 can also be movably mounted on the auxiliary shafts 105 .

[0036] In some embodiments, see Figure 4 As shown, a nut is installed on the correction frame 104, and the correction frame 104 is installed on the bidirectional threaded rod 103 through threaded engagement.

[0037] In some embodiments, see Figure 1 As shown in FIG4 , the bidirectional threaded rod 103 is rotatably mounted on the base frame 101 via a bearing, and an adjustment handle 106 is provided on either side of the bidirectional threaded rod 103 .

[0038] In some embodiments, see Figure 3 As shown, the mounting plate 205 and the U-shaped frame 206 are both provided with fixing knobs.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
