DETAILED DESCRIPTION
[0030] The utility model will be further explained in detail below in combination with the drawings and specific embodiments.
[0031] Example one
[0032] The embodiment discloses an organic silicon safety storage tank, and the overall structure of the safety storage tank is arranged as shown in the figure, comprising a horizontally arranged storage tank body 1 which can be supported and fixed on a supporting leg seat. Figure 1
[0033] At the same time, considering that liquid organic silicon is also sensitive to temperature, too high temperature can cause decomposition of organic silicon and reduce its performance; low temperature can cause hardening and embrittlement of organic silicon and affect its service life. Therefore, the organic silicon safety storage tank disclosed by the embodiment adopts a double-layer tank wall structure, and the double-layer tank wall has better performance in resisting changes of ambient temperature, so that a relatively stable environment can be provided for storage of liquid organic silicon.
[0034] Further, a liquid inlet 4 and a liquid outlet 6 are arranged on the storage tank body 1 and are respectively used for passing in and discharging liquid organic silicon. The liquid inlet 4 is located at the top position of the storage tank body 1 and is in communication with the inner cavity of the inner layer tank wall; the liquid outlet 6 is located at the bottom position of the storage tank body 1 and is in communication with the inner cavity of the inner layer tank wall.
[0035] In the dry state of the inner cavity of the storage tank body 1, liquid organic silicon is passed in at the liquid inlet 4, so that the liquid organic silicon enters the storage tank body for storage; when liquid organic silicon needs to be used, the liquid organic silicon is discharged at the liquid outlet 6 for use. In order to facilitate the opening and closing operation of the liquid inlet and the liquid outlet, and at the same time, the liquid inlet and the liquid outlet are not exposed, control valves are arranged at the liquid inlet and the liquid outlet respectively.
[0036] Further, for the storage tank body 1, it is provided with a manhole which needs to be communicated with the inner tank of the storage tank body 1. Considering that the sealing performance of the manhole of the existing chemical storage tank is poor, the sealing type manhole 3 with enhanced sealing performance is arranged at the top of the storage tank body 1.
[0037] As shown in Figure 2 and Figure 3 , the sealing type manhole 3 comprises a main seat 30 which is welded and fixed on the storage tank body 1 and communicated with the inner tank.
[0038] Further, the main seat 30 is hingedly connected with an upper cover 31 which has the performance of being flipped to open or close. In order to lock and fix the upper cover 31 with the main seat 30 when the upper cover 31 is closed, a lock catch assembly is further arranged between the main seat 30 and the upper cover 31.
[0039] Meanwhile, the main seat 30 and the upper cover 31 are both provided with a sealing gasket structure, specifically, a lower sealing gasket 39 is fixedly arranged along the circumferential edge of the top opening of the main seat 30, as shown in Figure 5 , the lower sealing gasket 39 is formed with an outer protruding ring 39a; and an upper sealing gasket 38 is fixedly arranged along the circumferential edge of the upper cover 31, as shown in Figure 6 , the lower sealing gasket 39 is formed with an inner protruding ring 38a.
[0040] The outer diameter of the inner protruding ring 38a is nearly consistent with the inner diameter of the outer protruding ring 39a (usually the outer diameter of the inner protruding ring 38a is slightly smaller than the inner diameter of the outer protruding ring 39a), when the upper cover 31 is closed on the main seat 30, the inner protruding ring 38a will be clamped into the outer protruding ring 39a, so that the protruding ring structure is extruded, and then the outer protruding ring 39a and the inner protruding ring 38a are in sealing contact, which provides good sealing performance for the sealing type manhole 3.
[0041] Therefore, for the organic silicon safety storage tank disclosed in the embodiment, the main seat 30 and the upper cover 31 are both provided with a sealing gasket structure, compared with a single layer sealing structure, the double-sided sealing structure has better sealing stability. Further, the sealing gasket is formed with a protruding ring structure, which is an inner protruding ring and an outer protruding ring respectively, when the upper cover is closed, the inner protruding ring is clamped into the outer protruding ring, with the protruding ring structure being extruded, the inner and outer protruding rings can be tightly contacted, realizing sealing, thereby improving the sealing performance of the sealing type manhole 3 of the embodiment, greatly reducing the probability of external humid gas or liquid penetrating into the storage tank body through the manhole, and then reducing the occurrence of liquid organic silicon hydrolysis, realizing more safe protection storage of liquid organic silicon.
[0042] Embodiment two
[0043] The embodiment discloses an organic silicon safety storage tank, which further discloses a hinged assembly and a lock catch assembly of the sealing type manhole 3 on the basis of the structure disclosed in the embodiment one.
[0044] The hinge assembly is used for the hinged connection of the upper cover 31 and the main body seat 30. As shown in Figure 4 The hinge assembly 32 comprises a hinge lug seat 321, a rotating shaft 322, a locking nut 323 and a connecting frame 324.
[0045] The hinge lug seat 321 is fixed on the main body seat 30 and has two lug structures, and a through hole is formed at the lug structure.
[0046] The connecting frame 324 is used for fixed connection with the upper cover 31, and the connecting frame 324 is hingedly connected with the hinge lug seat 321 to meet the use requirement of the flip opening or closing of the upper cover 31.
[0047] The connecting frame 324 and the hinge lug seat 321 are assembled and connected through the rotating shaft 322. A hole body structure matching the through hole of the hinge lug seat 321 is formed on the connecting frame 324, and the through hole of the hinge lug seat 321 and the connecting frame 324 is passed through by the rotating shaft 322, and then the end is locked and connected with the locking nut 323. Thus, taking the rotating shaft as the rotating point, the flip action of the upper cover 31 relative to the main body seat 30 is realized.
[0048] The lock catch assembly is used for the locking connection of the upper cover 31 and the main body seat 30, as shown in Figure 2 and Figure 3 The lock catch assembly comprises a lock hook 34, a lock plate seat 35 and a lock rod 37.
[0049] The lock hook 34 is fixed on the upper cover 31, and the bottom end of the lock hook 34 is extended downward to form an L-shaped hook tip. When the upper cover 31 is closed, the L-shaped hook tip is used for hooking the lock rod 37.
[0050] The lock plate seat 35 is fixed on the main body seat 30 and is symmetrically provided with two groups, and a locking hole is formed on the lock plate seat 35.
[0051] The lock rod is installed and arranged based on the lock plate seat and the locking hole, and the lock rod 37 is arranged between the two groups of lock plate seats 35, and the two ends of the lock rod 37 are respectively inserted into the locking holes.
[0052] The locking hole is designed to have a specific shape, specifically: the locking hole is composed of a translation part 35a and a locking circular hole part 35b which are integrally connected.
[0053] The depth of the locking circular hole part 35b is greater than that of the translation part 35a, and the translation part 35a provides guidance for the sliding of the lock rod 37.
[0054] Before the top cover 31 is closed, the locking rod 37 is located inside the translation section 35a. When the top cover 31 is closed, the locking hook 34 is lowered between the two locking plate seats. At this time, the locking rod 37 is pushed from the translation section 35a into the locking hole section 35b, so that the locking rod 37 presses against the locking hook 34, thereby achieving locking. Similarly, pushing the locking rod 37 from the locking hole section 35b back to the translation section 35a releases the pressure of the locking rod on the locking hook 34, thus enabling the opening operation of the top cover 31.
[0055] Preferably, in order to enable the lock hook to descend smoothly and disengage easily from the lock bar, the front end of the L-shaped hook tip of the lock hook 34 is set as an inclined surface 34a.
[0056] Furthermore, to facilitate the pushing operation of the locking rod 37, a locking rod handle 36 is provided on the locking rod 37, and the locking rod handle 36 can also prevent the locking rod 37 from disengaging from the locking hole under the limiting effect; correspondingly, to facilitate the opening and closing flipping operation of the upper cover 31, an upper cover handle 33 is provided on the upper cover 31.
[0057] In addition, a safety relief valve 2 is installed on the top of the storage tank 1. The safety relief valve 2 is a one-way valve, which plays a role in improving the safety of the storage tank 1.
[0058] like Figure 1 As shown, a climbing ladder 5 is provided on one side of the storage tank 1. The climbing ladder 5 leads to the location of the sealed maintenance manhole 3. Maintenance personnel can climb the climbing ladder 5 to carry out maintenance operations at the sealed maintenance manhole 3.
[0059] In summary, the organosilicon safety storage tank disclosed in this utility model improves the sealing performance of the maintenance manhole by utilizing a suitable upper and lower sealing gasket structure, providing a safer and more reliable sealed environment for the storage of organosilicon liquid. Simultaneously, the locking assembly is a self-locking structure; through the cooperation of the locking rod and the locking hook, the locking or opening operation of the top cover and the main body can be completed, offering the advantage of simple operation.
[0060] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
