Technical Field
[0001] This utility model relates to the field of chemical raw material storage technology, specifically a sealed iron drum for chemical raw materials with inlet and outlet. Background Technology
[0002] Chemical iron drums refer to iron containers used for storing, transporting, and mixing chemical raw materials and products. The national standard for these drums refers to those conforming to relevant Chinese industry standards. In the prior art, patent publication number CN 212862418U discloses an iron drum that is easy to pour, comprising an iron drum body with a top cover threadedly connected to the top; grooves on both sides of the iron drum body, with fixed rods fixedly connected inside the grooves; mounting blocks welded to both sides of the iron drum body, with rotating blocks movably connected between the mounting blocks; a handle fixedly connected to one side of each rotating block; and a rotating frame movably connected to the other side of the iron drum body. The advantages of this invention are: through the iron drum body, mounting blocks, rotating blocks, handles, grooves, and handles... The design of the lever allows for easier manual emptying of raw materials from the iron drum, solving the problem of inconvenient emptying of existing iron drums containing raw materials. The coordinated design of the iron drum body, rotating frame, pull belt, empty trough, and handle allows for more effortless and continuous emptying of raw materials, eliminating the need to bend over to operate the iron drum body, which is quite strenuous. However, when storing chemical raw materials, the inlet and outlet of the device are sealed by a threaded connection on the top cover, resulting in a relatively simple sealing structure with room for improvement. Therefore, we propose a chemical raw material iron drum with sealed inlet and outlet. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a chemical raw material iron drum with sealed inlet and outlet. The device adopts a multi-stage sealing method. Through the transmission element, during the threaded connection of the sealing cap at the inlet and outlet of the chemical raw material iron drum, it can simultaneously perform double sealing operations on the lower end of the inlet and outlet and the pipe opening, thereby improving the sealing performance at the inlet and outlet of the chemical raw material iron drum and effectively solving the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a chemical raw material iron drum with sealed inlet and outlet, including a chemical drum shell, an inlet and outlet pipe penetrating through the top wall of the chemical drum shell, a sealing cover connected to a threaded groove with an internal thread at the upper outer side of the inlet and outlet pipe, and also including a multi-stage sealing mechanism.
[0005] Multi-stage sealing mechanism: It includes a fixed seat, a telescopic column, a pressure seat, a synchronizing rod, a sealing seat, a conical ring, and a sealing assembly. The fixed seats are respectively set at the left and right ends of the inner wall of the inlet and outlet pipes. A pressure seat is set between the fixed seats through the telescopic end of the telescopic column. A sealing seat is set on the lower side of the pressure seat through the synchronizing rod. A conical ring is set at the lower end of the inner wall of the inlet and outlet pipes. Sealing assemblies are set on the top wall of the conical ring and the outer side of the sealing seat. This device adopts a multi-stage sealing method. Through the transmission element, during the threaded connection of the sealing cap of the inlet and outlet of the chemical raw material iron drum, it can simultaneously perform double sealing operations on the lower end of the inlet and outlet and the pipe opening, thereby improving the sealing performance of the inlet and outlet of the chemical raw material iron drum.
[0006] Furthermore, the upper outer side of the chemical drum shell is provided with two symmetrically distributed connecting seats. The middle of each connecting seat is rotatably connected to a lifting ring through a bearing. The end of the lifting ring away from the center of the chemical drum shell is provided with a rubber sleeve, which facilitates the lifting and moving of the sealed chemical raw material iron drum by the staff.
[0007] Furthermore, the multi-stage sealing mechanism also includes springs, which are respectively sleeved on the outer end of the telescopic column. One end of each spring is fixedly connected to the lower side of the pressure seat, and the other end of each spring is fixedly connected to the upper side of the adjacent fixed seat. The compression and reset force of the springs enables the sealing seat to automatically separate from the conical ring seal when the sealing cover is opened later.
[0008] Furthermore, the multi-stage sealing mechanism also includes an adjustment component, which includes a circular ring and a threaded ring. The circular ring is disposed on the top wall of the sealing cover. A second threaded groove is provided on the outer side of the circular ring. A threaded ring is threadedly connected to the inner side of the second threaded groove. The lower end of the threaded ring contacts the upper side of the pressure seat. The threaded ring adjusts the tightness of the compression seal between the sealing seat and the conical ring through the pressure seat.
[0009] Furthermore, the sealing assembly includes a sealing ring one and a sealing ring two, both of which are disposed on the top wall of the discharge pipe. Both sealing ring one and sealing ring two are installed in conjunction with the inlet and outlet pipes to seal the contact area between the outlet pipe and the sealing cap inside the chemical raw material iron drum.
[0010] Furthermore, the sealing assembly also includes a sealing ring three, which is disposed on the outer side of the sealing seat. The sealing ring three is installed in conjunction with the conical ring to seal the contact area between the sealing seat and the conical ring inside the chemical raw material iron drum for material inlet and outlet sealing.
[0011] Furthermore, the inner wall of the chemical drum shell is coated with polyurethane to improve the corrosion resistance of the inner wall of the sealed chemical raw material iron drum.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This sealed inlet and outlet iron drum for chemical raw materials has the following advantages:
[0013] When using chemical raw material iron drums with sealed inlet and outlet, the device adopts a multi-stage sealing method.

Detailed Implementation
[0017] 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.
[0018] Please see Figure 1-2This embodiment provides a technical solution: a sealed inlet and outlet iron drum for chemical raw materials, including a chemical drum shell 1, an inlet / outlet pipe 5 penetrating through the top wall of the chemical drum shell 1, a threaded groove with an internal thread connecting a sealing cap 6 at the upper outer side of the inlet / outlet pipe 5, two symmetrically distributed connecting seats 2 at the upper outer side of the chemical drum shell 1, a lifting ring 3 rotatably connected to the middle of each connecting seat 2 via a bearing, a rubber sleeve 4 at the end of the lifting ring 3 away from the center of the chemical drum shell 1, and a polyurethane coating on the inner wall of the chemical drum shell 1. When using the chemical raw material iron drum, the lifting ring 3 facilitates the movement of the chemical raw material iron drum by hand, and the rubber sleeve 4 improves the anti-slip ability between the hand and the lifting ring 3 during the hand lifting process. The polyurethane coating on the inner wall of the chemical drum shell 1 has good resistance to media containing chemical oxidants, improving the corrosion resistance of the device for storing chemical raw materials, and also includes a multi-stage sealing mechanism 7.
[0019] The multi-stage sealing mechanism 7 includes a fixed seat 71, a telescopic column 72, a pressure seat 74, a synchronizing rod 75, a sealing seat 76, a conical ring 77, and a sealing assembly 79. The fixed seats 71 are respectively located at the left and right ends of the inner wall of the inlet / outlet pipe 5. A pressure seat 74 is provided between the fixed seats 71 through the telescopic end of the telescopic column 72. A sealing seat 76 is provided on the lower side of the pressure seat 74 through the synchronizing rod 75. A conical ring 77 is provided at the lower end of the inner wall of the inlet / outlet pipe 5. The top wall of the conical ring 77 and the outer side of the sealing seat 76 are both provided with sealing assemblies 79. The multi-stage sealing mechanism 7 also includes springs 73. The springs 73 are respectively sleeved on the outer end of the telescopic column 72. One end of each spring 73 is fixedly connected to the lower side of the pressure seat 74, and the other end of each spring 73 is connected to the upper side of the adjacent fixed seat 71. The side-fixed connection and multi-stage sealing mechanism 7 also include an adjusting component 78, which includes a circular ring 781 and a threaded ring 782. The circular ring 781 is disposed on the top wall of the sealing cover 6, and a second threaded groove is opened on the outer side of the circular ring 781. The threaded ring 782 is threadedly connected to the inner side of the second threaded groove. The lower end of the threaded ring 782 contacts the upper side of the pressure seat 74. The sealing component 79 includes a first sealing ring 791 and a second sealing ring 792, both of which are disposed on the top wall of the discharge pipe 5 and are installed in conjunction with the inlet and outlet pipes 5. The sealing component 79 also includes a third sealing ring 793, which is disposed on the outer side of the sealing seat 76 and is installed in conjunction with the conical ring 77. When sealing the inlet and outlet of the chemical raw material drum, the worker vertically attaches the sealing cap 6 to the upper outer side of the inlet / outlet pipe 5 from top to bottom. Then, the sealing cap 6 is rotated to move vertically downwards through its threaded connection with the threaded groove. The sealing cap 6 causes the lower end of the threaded ring 782 to press against the upper side of the pressure seat 74. The pressure seat 74, under pressure, overcomes the compressive force of the spring 73, thus driving the sealing seat 76 downwards via the synchronizing rod 75. When the sealing cap 6 rotates and moves downwards to a certain extent, the upper end of the inlet / outlet pipe 5 contacts the sealing ring 791 and sealing ring 792 inside the sealing cap 6. During this process, the outer edge of the upper end of the inlet / outlet pipe 5 presses against the inclined surface of sealing ring 791, and the inner edge of the upper end of the inlet / outlet pipe 5 contacts sealing ring 792. The inclined surfaces of the two parts (2 and 2) press against each other, causing the sealing rings 791 and 792 to deform under pressure and adaptively fit into contact with the inlet / outlet pipe 5. The seal between the outer edge of the inlet / outlet pipe 5 and the sealing ring 791, and between the inner edge of the inlet / outlet pipe 5 and the sealing ring 792, gradually transitions from a line seal to a surface seal, resulting in a tighter rubber seal at this location. This improves the sealing effect between the inlet / outlet pipe 5 and the sealing cover 6. Simultaneously, the sealing seat 76 moves downward and contacts and presses against the conical ring 77, causing the sealing ring 793 to deform under pressure. This seals the inside of the inlet / outlet of the chemical raw material drum. By sealing both the inside and outside of the inlet / outlet of the chemical raw material drum, the sealing effect is achieved.This improves the sealing effect of the device at the inlet and outlet of the chemical raw material iron drum. When the sealing cover 6 is rotated in the reverse direction to release the blockage of the inlet and outlet pipe 5, the compression and reset force of the spring 73 causes the sealing seat 76 to automatically move upward and separate from the conical ring 77, thus achieving self-separation of the internal seal of the inlet and outlet pipe 5. Rotating the threaded ring 782 allows it to move vertically downward along the outer side of the ring 781 through its threaded connection with the threaded groove, thereby adjusting the distance between the lower end of the threaded ring 782 and the top wall of the sealing cover 6. This further adjusts the tightness of the compression seal between the sealing seat 76 and the conical ring 77 via the pressure seat 74. This device employs a multi-stage sealing method. Through the transmission element, during the threaded connection of the sealing cover 6 at the inlet and outlet of the chemical raw material iron drum, it can simultaneously perform double sealing operations on the lower internal end of the inlet and outlet and the pipe opening, thereby improving the sealing performance at the inlet and outlet of the chemical raw material iron drum.
[0020] The working principle of the chemical raw material iron drum with inlet and outlet sealing provided by this utility model is as follows: When using the chemical raw material iron drum, the lifting ring 3 facilitates the movement of the chemical raw material iron drum by hand. The rubber sleeve 4 improves the anti-slip ability between the hand and the lifting ring 3 during the process of the worker lifting the lifting ring 3. When sealing the inlet and outlet of the chemical raw material iron drum, the worker puts the sealing cover 6 vertically on the upper outer side of the inlet and outlet pipe 5 from top to bottom, and then rotates the sealing cover 6 so that it moves vertically downward through the threaded connection with the threaded groove. The sealing cover 6 drives the lower end of the threaded ring 782 to press and contact the upper side of the pressure seat 74. 74 is compressed, overcoming the compressive force of spring 73, thereby driving the sealing seat 76 to move downward through the synchronizing rod 75. When the sealing cover 6 rotates and moves downward to a certain extent, the upper end of the inlet / outlet pipe 5 contacts the sealing ring 791 and sealing ring 792 inside the sealing cover 6. During this process, the outer edge of the upper end of the inlet / outlet pipe 5 is pressed against the inclined surface of sealing ring 791, and the inner edge of the upper end of the inlet / outlet pipe 5 is pressed against the inclined surface of sealing ring 792. As the two are pressed together, sealing rings 791 and 792 deform under pressure and adaptively fit against the inlet / outlet pipe 5. The outer edge of the upper end of the inlet / outlet pipe 5 is pressed against the sealing ring 791. The seal between the inner edge of the inlet / outlet pipe 5 and the sealing ring 792 gradually transitions from a line seal to a surface seal, resulting in a tighter rubber seal at this location. This improves the sealing effect between the inlet / outlet pipe 5 and the sealing cover 6. Simultaneously, the sealing seat 76 moves downwards and contacts and presses against the conical ring 77, causing the sealing ring 793 to deform under pressure. This seals the inside of the inlet / outlet of the chemical raw material drum. By sealing both the inside and outside of the inlet / outlet of the chemical raw material drum, the sealing effect of the device is improved. When the sealing cover 6 is rotated in the reverse direction to release the seal on the inlet / outlet pipe 5, the spring 7... The compression and reset elasticity of 3 causes the sealing seat 76 to automatically move upward and separate from the conical ring 77, thereby achieving self-separation of the internal seal of the inlet and outlet pipe 5. Rotating the threaded ring 782 causes it to move vertically downward along the outer side of the ring 781 through the threaded connection with the threaded groove, thereby adjusting the distance between the lower end of the threaded ring 782 and the top wall of the sealing cover 6. This allows for adjustment of the tightness of the compression seal between the sealing seat 76 and the conical ring 77 by the pressure seat 74. The inner wall of the chemical drum shell 1 is coated with polyurethane. The polyurethane coating has good resistance to media containing chemical oxidants, improving the corrosion resistance of the device for storing chemical raw materials.
