Large and small cover barrel opening device for chemical production

Abstract

The utility model relates to the technical field of chemical industry, and discloses a large and small cover barrel opening device for chemical industry production, which comprises a tank body, a small cover is arranged on the tank body, and two first iron sheets are fixedly arranged in the small cover. Due to the existence of the abutting block, when the abutting block abuts against the inner wall of the small cover, the inner wall of the small cover can be a stress surface through contact friction generated between the abutting block and the small cover, so that when the small cover is screwed to be opened, the first iron sheet is stressed more uniformly, the inner wall of the small cover can provide an additional stress point, the stress strength of the whole small cover is enhanced, and the service life of the small cover is prolonged. The effect of dispersing the stress of the first iron sheets is achieved, and the problems that due to the lever effect of a copper wrench during cover opening, the two first iron sheets are prone to deformation during recycling, and after long-time use, the small cover deforms and is difficult to tighten and open are solved.

Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a barrel opening device for large and small covered barrels used in chemical production. Background Art

[0002] In the chemical production process, the storage and processing of raw materials is one of the core links. Barreled chemicals are widely used in the chemical industry because of their easy transportation and storage. The products of the polyester polyol industry are usually packaged in open barrels with large and small lids. The barrel has a large lid with a small twistable lid attached to it, and two iron sheets protrude from the groove inside the circular lid.

[0003] In the prior art, workers usually use a copper wrench to open the lid. The wrench adopts a hoe-like structure. One end of the wrench is stuck between the two iron sheets of the barrel cover to form a lever between the wrench and the iron sheet, and then the lid is twisted to open. However, since polyester polyol products are easy to solidify, barreled materials often need to be baked, and there is pressure inside the barrel after baking. At this time, the small cover is pried open by the leverage of the wrench, and the pressure in the barrel bursts out, which can easily blow the small cover away without any obstruction. The material in the barrel is also easy to fly out of the barrel under the action of pressure. In addition, due to the leverage when opening the lid, the two iron sheets on the small cover are easily deformed during cyclic use. After long-term use, the small cover is deformed and difficult to tighten and open. Based on this, the applicant purposefully provides a barrel opening device for large and small barrels for chemical production that can improve the stability of opening the lid. Utility Model Content

[0004] The utility model aims to address the deficiencies of the prior art and to provide a barrel opening device for chemical production with large and small lids that can improve the stability of opening the lid, so as to solve the technical problem in the prior art that using a wrench to open the lid easily causes deformation of the iron sheet, resulting in difficulty in tightening and opening the small lid.

[0014] Beneficial effects of the utility model:

[0015] 1. In the utility model, the slot formed by the fixed block and the semicircular block can make the entire first iron sheet a force-bearing surface, and due to the presence of the abutment block, when the abutment block abuts against the inner wall of the small cover, the contact friction generated between the two can also make the inner wall of the small cover a force-bearing surface, so that when the small cover is twisted to open, the force on the first iron sheet is more uniform, and the inner wall of the small cover can also provide additional force points, which not only strengthens the force strength of the entire small cover, but also has the effect of dispersing the force on the first iron sheet, avoiding the problem that the copper wrench is prone to deformation of the two first iron sheets during cyclic use due to the lever effect when opening the cover, and causing the small cover to be deformed and difficult to tighten and open after long-term use;

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 7 As shown, the utility model is a barrel opening device for large and small covered barrels for chemical production, comprising:

[0029] A can body 1 is provided with a small cover 2, and two first iron sheets 201 are fixedly installed in the small cover 2; and

[0030] A round rod 3, with two semicircular blocks 7 fixedly installed at its bottom, and a fixed block 6 fixedly installed at its bottom, the fixed block 6 and the semicircular block 7 are both slidably matched with the small cover 2, the fixed block 6 is located between the two semicircular blocks 7, and it and the two semicircular blocks 7 respectively form two card grooves 301, the two card grooves 301 are respectively slidably matched with the two first iron sheets 201, a linkage component is provided in each semicircular block 7, and an abutment block 8 is slidably installed therein, when the semicircular block 7 is inserted into the small cover 2, the linkage component pushes the abutment block 8 to abut the inner wall of the small cover 2, and a rotating handle 4 is fixedly installed on the top of the round rod 3.

[0031] In actual application of this embodiment, when it is necessary to open the small cover 2, the round rod 3 is manually held by hand, and the fixed block 6 and the semicircular block 7 at the bottom thereof are inserted into the small cover 2, ensuring that the card slot 301 is inserted along the first iron sheet 201, and under the action of the linkage assembly, the abutment block 8 in the semicircular block 7 will move toward the inner wall of the small cover 2, and finally the abutment block 8 will abut against the inner wall of the small cover 2. At this time, the rotating handle 4 is manually rotated to drive the round rod 3 to rotate, so that the small cover 2 can be screwed off from the tank body 1, and after being screwed off, since the abutment block 8 abuts against the inner wall of the small cover 2, it can be ensured that the small cover 2 is always engaged with the fixed block 6 and the semicircular block 7, avoiding the situation where the pressure in the tank body 1 will cause the small cover 2 to fly off;

[0032] The card slot 301 formed by the fixing block 6 and the semicircular block 7 can make the entire first iron sheet 201 a force-bearing surface, and due to the existence of the abutting block 8, when the abutting block 8 abuts against the inner wall of the small cover 2, the contact friction generated between the two can also make the inner wall of the small cover 2 a force-bearing surface. In this way, when the small cover 2 is twisted to open the cover, the force on the first iron sheet 201 is more uniform, and the inner wall of the small cover 2 can also provide additional force points, which not only strengthens the force strength of the entire small cover 2, but also has the effect of dispersing the force on the first iron sheet 201, avoiding the problem that the copper wrench is easily deformed due to the lever effect when opening the cover during cyclic use, which causes the small cover 2 to be deformed and difficult to tighten and open after long-term use.

[0033] like Figure 1-Figure 6As shown, as a preferred embodiment of the utility model, the linkage assembly includes a circular wheel 801, a transverse groove 701, a U-shaped frame 9 and a guide groove 901, the transverse groove 701 is opened in the semicircular block 7, the U-shaped frame 9 is slidably installed in the semicircular block 7, and its bottom end passes through the bottom of the semicircular block 7, the guide groove 901 is opened on the U-shaped frame 9, and it is arranged obliquely, the horizontal height of the guide groove 901 away from the fixed block 6 is lower than the horizontal height of the end close to the fixed block 6, the circular wheel 801 is fixedly installed on the abutment block 8, it is slidably connected with the transverse groove 701, and it is slidably connected with the guide groove 901.

[0034] In practical application, this embodiment is based on Figure 7 As shown in the figure, the semicircular block 7 is not inserted into the small cover 2. At this time, the bottom end of the U-shaped frame 9 protrudes from the bottom of the semicircular block 7. As the semicircular block 7 is inserted into the small cover 2, the U-shaped frame 9 protruding from its bottom end will first contact the bottom plate of the small cover 2. At this time, the continued insertion of the semicircular block 7 will cause the U-shaped frame 9 to slide upward inside the semicircular block 7, and the position of the circular wheel 801 in the guide groove 901 will change accordingly. Since the circular wheel 801 slides in the transverse groove 701, when the U-shaped frame 9 slides upward, the circular wheel 801 will drive the abutment block 8 to move toward the inner wall of the small cover 2. Finally, when the semicircular block 7 is fully inserted into the small cover 2, the abutment block 8 abuts against the inner wall of the small cover 2, thereby achieving an automatic locking effect, and the locking effect of the abutment block 8 on the small cover 2 still exists until the small cover 2 is unscrewed, but the small cover 2 can be manually pulled out from the bottom of the round rod 3.

[0035] like Figure 3-Figure 7 As shown, as a preferred embodiment of the utility model, a second receiving groove 702 is opened in the semicircular block 7, a first receiving groove 302 is opened at the bottom of the round rod 3, the first receiving groove 302 is connected to the second receiving groove 702, and the top end of the U-shaped frame 9 is slidably connected to the first receiving groove 302 and the second receiving groove 702.

[0036] In actual application of this embodiment, when the semicircular block 7 is not inserted into the small cover 2, the top end of the U-shaped frame 9 is located in the second receiving groove 702, and when the semicircular block 7 is fully inserted into the small cover 2, the top end of the U-shaped frame 9 will slide from the second receiving groove 702 to the first receiving groove 302.

[0037] like Figure 1-Figure 4 As shown, as a preferred embodiment of the utility model, a sliding rod 5 is slidably connected inside the round rod 3, the bottom end of the sliding rod 5 is located in the first receiving groove 302, and the top end thereof passes through the rotating handle 4.

[0038] When the present embodiment is actually applied, a sliding rod 5 is slidably arranged in the round rod 3. When the semicircular block 7 is fully inserted into the small cover 2 and the top end of the U-shaped frame 9 slides into the first receiving groove 302, the U-shaped frame 9 will push the end of the sliding rod 5 located in the first receiving groove 302, so that the top end of the sliding rod 5 is more protruding from the rotating handle 4. When the small cover 2 is unscrewed, the small cover 2 is still locked by the abutment block 8. At this time, it is only necessary to press the sliding rod 5 toward the inside of the round rod 3 so that the sliding rod 5 pushes the U-shaped frame 9 to move the U-shaped frame 9 downward. On the one hand, the downward movement of the U-shaped frame 9 will drive the abutment block 8 to move into the semicircular block 7 to complete the unlocking of the small cover 2. On the other hand, the bottom end of the U-shaped frame 9 will directly push the small cover 2, so that the small cover 2 is away from the fixed block 6 and the semicircular block 7, thereby realizing direct separation without the need for manual removal of the small cover 2.

[0039] like Figure 1-Figure 3 As shown, as a preferred embodiment of the utility model, the outer circumferential surface of the round rod 3 is sleeved with a side fan-shaped baffle 10, and the bottom of the side fan-shaped baffle 10 is provided with a bottom buckle 11, and the bottom buckle 11 is snap-fitted with the edge of the barrel cover of the tank body 1.

[0040] In actual application of this embodiment, the side fan-shaped baffle 10 can prevent the internal pressure of the barrel after the material is baked from spraying out the material when the lid is opened and causing burns to people, and the bottom buckle 11 at the bottom of the side fan-shaped baffle 10 can clamp the barrel hoop at the edge of the tank body 1 to prevent the internal pressure of the barrel from breaking open the side fan-shaped baffle 10.

[0041] like Figure 1-Figure 3 As shown, as a preferred embodiment of the utility model, an upper baffle 12 is fixedly installed on the outer circumferential surface of the round rod 3, and the upper baffle 12 is located above the side fan-shaped baffle 10.

[0042] In actual application of this embodiment, the upper baffle 12 is provided to prevent the material in the barrel from splashing upward and injuring workers, further reducing the risk when opening the lid.

[0043] Working principle of the utility model: the above embodiment of the utility model provides a barrel opening device for large and small covered barrels for chemical production. When the small cover 2 needs to be opened, the round rod 3 is manually held, and the fixed block 6 and the semicircular block 7 at the bottom thereof are inserted into the small cover 2, ensuring that the card slot 301 is inserted along the first iron sheet 201. Under the action of the linkage assembly, the abutment block 8 in the semicircular block 7 will move toward the inner wall of the small cover 2, and finally the abutment block 8 will abut against the inner wall of the small cover 2. At this time, the rotating handle 4 is manually rotated to drive the round rod 3 to rotate, so that the small cover 2 can be unscrewed from the tank body 1. After unscrewing, since the abutment block 8 abuts against the inner wall of the small cover 2, it can be ensured that the small cover 2 is always engaged with the fixed block 6 and the semicircular block 7, avoiding the situation where the pressure in the tank body 1 will spray the small cover 2 away.

[0044] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
